功能描述

WCS

Description of function of the WCS

Description of function

The WCS position encoding system comprises in

the main two components: the code rail, which is

the information carrier for the absolute code, and

the reading head, which scans the code rail opto-

electronically.

The code rail is installed parallel to the runway of

the vehicle and thus assigns a clear position to

each point on the runway. It is possible to install

the code rail only where positioning is required.

The system permits the code rail to be installed in

bends and branches to be constructed.

The code rail is manufactured individually for each

order and is supplied in a coil. Unless ordered

otherwise, the code rail always begins with a posi-

tional value of 0. The maximum length of the code

rail is 327 m. Numerous fitting aids are available

for speedy installation of the code rail.

The code rail is scanned with a U-shaped reading

head. The reading head detects a new positional

value every 0.8 mm (WCS3) or 0.833 mm (WCS2).

After being placed onto the code rail, the reading

head calculates the positional value without refe-

rence points and without delays.

Scanning the code rail is reproducible, reliable and

independent of temperature fluctuations even at

very high velocities The positional value can be

transmitted directly from the reading head to the

control via a serial RS 485 interface or an SSI in-

terface.

Various interface modules are available for con-

nection to standard interfaces,

such as:

-Parallel

-Profibus DP

-DeviceNet

-InterBus-S

-CANopen

-SSI

Up to four reading heads can be connected simul-

taneously to all the interface modules apart from

the SSI interface.

WCS

Areas of application and application examples

Areas of application of the WCS

The WCS can be used wherever vehicles are to be

positioned automatically with millimetre accuracy.

The principle of functioning of the WCS permits the

most varied applications, e. g.

-Breaks in the code rail

(change of aisle, switch points)

-Applications with curved and circular runways

-Use of several vehicles behind one another

The increased tolerances of the reading head to

the code rail permit the WCS3 system to be used

for most applications. However in some cases it

may be of advantage to use the WCS2 in con-

junction with the aluminium profile system (p. 16ff).

Here are some examples from the wide range of

possible applications:

Storage and retrieval machines

(high bay warehouses)

Carriages, lifting and lowering stations and traver-

sing carriages are positioned by one reading head

each. The positioning is always absolutely repro-

ducible independent of the length of the code rail.

We recommend the WCS3 system for new high

bay warehouses.

For retrofitting older warehouses, it may be of ad-

vantage to use the WCS2 in conjunction with the

aluminium profile system (p. 16ff):

-simple retrofitting

-high mechanical tolerances possible between

measuring system and carriage

-isolation from travel vibrations

Automatic cranes

Automatic cranes are a typical application case for

the WCS2 in conjunction with the aluminium profile

system. The crane is positioned by a reading head

for both crane and cross travel. The guide trolley

ensures the optimum position of the reading head

to the code rail at any point and isolates it from any

vibrations on the crane runway.

As an option, brushes for cleaning the code rail

can be fitted to the guide trolley. The WCS2 can

then also be used in very dusty ambiences, e. g. in

cement plants or foundries.

Lifts and lifting/lowering stations

The WCS3 offers the optimum solution for these

applications. The WCS3 reading head scans the

code rail without contact. This has several advan-

tages:

-silent

-no mechanical wear

-long service life

Acceleration and braking ramps can be optimised

by means of the continuous positional measure-

ment. The mounting brackets for the code rail

(p. 14f) permit quick and easy installation of the

code rail in the lift shaft.

WCS

Areas of application and application examples

Galvanising plants

One or more carriages travel behind one another

on a straight runway. The carriages transport the

material to be galvanised automatically to the rele-

vant bath. The WCS has proven itself to be parti-

cularly successful for this application. The WCSA

reading heads are distinguished by a higher lumi-

nous efficiency. Thanks to this, the maintenance

intervals (cleaning the gap in the reading head) are

perceptibly lengthened.

Apart from the WCS3 system, the WCS2 with alu-

minium profile system which is also available with

powder coating, can be used.

Overhead conveyors

A large number of trolleys must be positioned on a

circular runway - the WCS offers the optimum solu-

tion. Branches (switch points) and bends are pos-

sible. The WCS3 is particularly suitable for this

application.

After a power cut, the current position of the trolley

is transmitted to the control without delay, the trol-

ley need not be moved.

The WCS can also be used for routes longer than

327 m. We would be pleased to assist you in wor-

king out a solution for your particular application.

Please contact us.

WCS3

Studio and theatre equipment

In addition to numerous applications in material

handling, the WCS3 has also proven itself in televi-

sion studios and theatres. Here the WCS is used

for positioning studio/stage lighting and revolving

stages (application with circular runway). Its cha-

racteristics such as silent operation, long service

life and reliability offer the user many advantages.

Particular emphasis must be placed on the mainte-

nance-friendliness of the WCS. If it should be ne-

cessary to replace a reading head, it can be dis-

mantled and refitted within a few seconds. Adjust-

ment is not necessary.

WCS

WCS3

Vehicle identification

This, apart from positioning conveying

vehicles, is an additional application for the WCS

system. A short (clearly defined) section of code

rail is attached to each vehicle, the reading head is

fixed. With a length of code rail of 20 cm on each

vehicle, over 1,500 vehicles can be differently co-

ded.

The positional values, i. e. the vehicle code, are

reliably recognised independent of the vehicle mo-

tions (vibrations, forwarding and reversing). The

WCS3 is used for this application.

The housing of the reading head is made of tough

plastic (protection class IP54). The mounting plate

for attaching the reading head and the mating part

of the plug connector for electrical connection are

part of the supply.

On the inside of the reading head (see also dra-

wings on next page) there are easily replaceable,

transparent plastic liners to protect the reading

area from dirt and damage. There are identification

notches on these liners. These serve to set the

zero point for vertical play (z-axis) of the reading

head. The reference point is the top edge of the

code rail. The reading head can move around the

reference point within the specified tolerances:

WCS2: ±5 mm, WCS3: ±10 mm. If the vertical play

is exceeded, the reading head signals "OUT" (rea-

ding head outside code rail) to the control.

The tolerances for lateral play (y-axis) are given by

the width of the gap in the reading head. Based on

a central position of the reading head above the

code rail, the free play is:

WCS2: ±5 mm, WCS3: ±12.5 mm.

WCS3: ±10 mm

WCS2: ±5 mm,

"OUT"

WCS2: ±5 mm,

WCS3: ±12.5 mm

b: ±5°

The positions are reliably detected in both vertical

(a: ±10°) and horizontal (b: ±5°) inclined positions,

and in bends down to a minimum of 500 mm. If the

positional value cannot be detected, e.g. because

the optical elements are soiled, the reading head

transmits a clear error code.

WCS2A/WCS3A

The hardware and software has been redeveloped

on the basis of the existing WCS reading heads,

utilising new technologies. This can also be seen

from the name - WCS3A. The additional "A" stands

for "advanced technology." The A types are com-

patible with previously supplied reading heads and

have improved characteristics:

-Automatic adustment of light output dependent

upon the degree of dirt accumulation on the op-

tics. This further increases the robustness of rea-

ding heads when dirt builds up.

-Detection of dirt accumulation during operation

(= warning signal)

-Higher ambient temperature up to 60 °C

In addition, the following characteristics of the

WCS3A reading head are new:

-Reliable reading in real time up to a velocity of

12.5 m/s (WCS3: 5.0 m/s)

-Optional 7 segment display integrated into rea-

ding head

-Optional digital output when adjustable limit

velocity is exceeded

WCS reading head

Installation of reading head

The reading head is generally fitted to the vehicle. Howe-

ver it is also possible to install the reading head in a

stationary position and attach a section of code rail to

the vehicle (vehicle identification, see also p. 7).

A special mounting plate is part of the supply of the rea-

ding head. This is attached to the vehicle. If the WCS2

is used with the aluminium profile system and guide

trolley, the mounting plate is already integrated into the

guide trolley. There are dovetail guides with a quick-

action lock on three sides of the reading head housing.

Using one of these guides as required, the reading head

is snapped into place on the guide bar. Thanks to this

quick-action lock, the reading head can be installed very

simply without any adjustment, and replaced quickly if

required.

The reading head can be installed in any position. It is

tough and will function reliably even in a rugged industrial

environment. The reading head is not vulnerable to exter-

nal light sources. However strong sunlight must be pre-

vented from shining directly into the gap in the reading

head.

To ensure long-term fault-free functioning, we recom-

mend ensuring during installation that the gap in the rea-

ding head is protected from dirt and any vapours. The

reading head must be fitted so that the electric connec-

tor plug points in the direction of the ascending positional

values on the code rail.

Mounting plate

The mounting plate is attached to the vehicle with M4

screws. When designing the system, we recommend

providing oblong holes to enable the position of the

mounting plate and thus the reading head to be correc-

ted. For installation, the dovetail groove of the reading

head is pushed over the bar on the mounting plate until

the spring tongue snaps into place. To remove the rea-

ding head, the spring tongue is released by turning slight-

ly with a screwdriver and the reading head pushed out of

the guide. The mounting plate is for all reading head

types identical.

Replacement of plastic liners

The plastic liners of the reading head can be replaced

quickly if they are damaged or soiled. Unscrew the two

cross-head screws on each liner and pull off the liner. Fit

in reverse order. The cross-head screws must be tighte-

ned with a max. torque of 0.5 Nm.

We recommend always replacing both liners and also

replacing the seal.

The plastic liners are available as a spare part.

WCS2/WCS3 code rail

The code rail, which carries the absolute code, differs

for the WCS2 and the WCS3 and thus cannot be inter-

changed between the two systems. In the case of the

WCS3, the height of the code rail is always 70 mm, for

the WCS2 the code rail can be supplied 55 mm or

70 mm high. Two different materials which have pro-

ven their suitability in practice are available for the

code rail: plastic laminate and stainless steel.

The code rail is supplied in a coil. Unless ordered

otherwise, the code rail always begins with a positional

value of 0.

The black plastic laminate code rail is made of a spe-

cial polyester laminate. It is distinguished by excellent

physical and chemical characteristics with a low dead-

weight. It is extremely elastic and resistant to tearing and

tear growth stresses. The material is neutral vis-à-vis

oils, greases and solvents. Thanks to its resistance to

acids, lyes and aggressive gases, this material is also

suitable for use in galvanising plants.

The laminate code rail is supplied as standard with holes

for mounting (WCS3-CS70-L1, see also drawing below).

When you use a bracket system to install the code rail,

e. g. as shown on page 14, we recommend using the

code rail without holes for mounting (WCS3-CS70-L0).

The laminate code rail can be used within a temperature

range of -40 °C ... 60 °C. Temperatures above 70 °C

lead to material deformation. The specific thermal expan-

sion coefficient is about 2.8 x 10

-5

1/K. Due to the mate-

rial characteristics, the laminate code rail must not be

installed at temperatures below 10 °C. For applications

with high temperature fluctuations (> 50 K) we recom-

mend using the stainless steel code rail.

WCS2/WCS3

WCS2/WCS3 code rail

The stainless steel code rail is manufactured in cor-

rosion-resistant spring steel. It is rust-proof and dis-

plays high mechanical stability and low thermal expan-

sion. The stainless steel code rail can be used within a

temperature range of -40 °C ... 100 °C.

The specific thermal expansion coefficient is

1.6 x 10

-5

1/K.

Protective gloves must be worn when installing the

stainless steel code rail.

Intalling the code rail

If the positional measurement of a section is to be

uninterrupted, the rail must be fitted in one piece. Basi-

cally there are many methods of fixing the code rail

dependent on the conditions of the application. The

simplest method of installing the code rail is screwing it

down to suitable brackets. When fitting, care must be

taken that the vertical and horizontal tolerances speci-

fied for the relevant reading head are observed.

Grounding of the WCS code rail

We have recommended the grounding of the WCS

code rail up to now. From now on, we regulate the

connection of the code rail with the system ground. The

laminate code rail has to be grounded, too, as the

surface of the laminate code rail is conductive. You will

find the detailed information for the shielding of the

code rail in the Internet version of the WCS catalogue –

beginning with version 10/2006 (file

tdoct0771d_). The description is included in the

chapters of the different installation systems.

Installation of the code rail in the mounting bracket

system：

When using the mounting bracket system, please note

that the code rail is grounded via the brackets

(WCS-MB*). If the brackets have no connection with the

system potential, at least one bracket has to be

grounded at a maximum distance of 40 meters. The

code rail also has to be grounded in circle applications

by using the bended brackets and the stabilizing profile

(WCS-MB*-B and WCS-SP2).

Tensioning device for the stainless steel code rail

Using the tensioning device prevents the stainless

steel code rail buckling due to temperature fluctuations

after installation. It also facilitates installation. Three

holes are punched at the beginning and at the end of

the stainless steel rail and can be used to attach the

tensioning device.

There are two possibilities when using the tensioning

device:

code rail is fixed at one end and tensioned at the

other end using the tensioning device.

code rail is fixed in the middle and tensioned at

both ends using the tensioning device. This method

is of advantage for longer sections (> 50 m).

Mounting bracket system for code rail

Installing code rail with mounting

bracket system

( 30 mm x 32 mm )

A new bracket system has been developed for

rapid installation of the WCS code rail.

It consists of brackets for installing straight sec-

tions (Fig. 1) of the code rail, and brackets for in-

stalling the code rail in bends and on circular run-

ways (Fig. 5). The brackets are made of galva-

nised steel plate and supplied pre-assembled.

The mounting brackets can be supplied in two

different designs: a screw-on bracket (Fig. 2) is

bolted onto the substructure, the bracket for instal-

lation in C profile (Fig. 3, 6) is intended for installa-

tion in a C profile rail (30 mm x 32 mm). The brak-

ket system can be used for installing both the lami-

nate and the stainless steel code rails.

Straight section

The mounting brackets for installing straight sec-

tions are fitted to the substructure at intervals of

max. 1.25 m along the runway. The code rail is

pushed into the bracket until it makes contact.

Then the code rail is tensioned and clamped in the

bracket by screwing down the two spanner bolts

(M6 x 12). Tensioning is by pulling on the free end

of the code rail. The counternuts of the bolts are

pressed into the plate of the bracket, i. e. it is not

necessary to hold the nuts down.

When installed correctly, the clamping force on the

brackets is sufficient to prevent the code rail being

pulled out of the bracket.

In addition to clamping, the code rail can be bolted to

the bracket. The two upper unused holes of the

bracket are used for this (M6). Bolting produces a

fixed point between code rail and substructure.

The bolts for the fixed point are not part of the sup-

ply. We recommend at least one fixed point in the

middle of the runway.

It is of advantage to use C profiles for installing the

brackets. They are arranged lengthwise or at right

angles to the travel path. The brackets for installa-

tion in C profile can easily be fixed and aligned in

the profiles.

Mounting bracket system for code rail

Bend

To produce bends, the mounting brackets for

bends (bend brackets, Figs. 5 and 6) are used

together with a special stabilising profile

(WCS-SP2). The stabilising profile is supplied as a

coil of the length ordered.

The bend brackets are so designed that no vertical

or horizontal offset of the code rail occurs when

moving from the straight section to the bend.

The bend brackets are mounted tangentially along

the arc of the circle or bend (max. support distance

0.7 m, recommended 0.5 m). Then the stabilising

profile is cut to the length of the bend and fitted

into the bend brackets. The code rail is now pu-

shed completely into the groove of the stabilising

profile. Finally the code rail together with the stabi-

lising profile is clamped onto the bend brackets by

means of the clamping screws (M4; allen screws)

and locked with the self-tapping screw supplied.

Circular runway

The following must be observed in the case of a

closed runway (circular runway, oval, ...). Due to

the method of functioning of the WCS, a gap of at

least one reading head length (85 mm) must be

left between the end and the beginning of the code

rail (see also p. 64). At this point, the control recei-

ves the value "OUT"-reading head outside code

rail. If continuous position information is necessary,

two reading heads behind one another must be

used.

Installation position of code rail

The code rail can be installed in any position desi-

red (see Fig. 7). When installing the code rail, care

must be taken that all the mounting brackets are

installed at the same level, i. e. the surface on

which the brackets are installed must be flat.

Powder-coated version

The mounting bracket for straight sections is also

available in a powder-coated version. In this versi-

on, the fixing screws are stainless steel (4VA).

A special aluminium profile system has been de-

veloped for the rapid installation of the 55 mm high

WCS2 code rail in plastic laminate or stainless steel.

The aluminium profile rail is designed to take the code

rail and a guide trolley. The guide trolley always ensu-

res the optimum position of the reading head in relati-

on to the code rail and compensates for tolerances

between the vehicle and the WCS system. At the

same time, the reading head is isolated from the vehic-

le vibrations. The aluminium profile system can be

fitted in any position. The profile rails are supplied in

5 m sections and the ends are mitred to 45°.

On request, the aluminium profile rail can also be sup-

plied powder-coated and in curved sections.

Installing the aluminium profile rail

Rail holders, into which the profile rail is clipped, are

available for rapid installation of the aluminium profile

rail. The rail holders are available in two different versi-

ons: the screw-on holder is bolted to the substructure,

the holder for fitting in a C profile is designed for instal-

lation in a C profile rail (30 mm x 32 mm). The suspen-

sion distance for the aluminium profile rail must not

exceed 1.5 m (min. 3 rail holders per 5 m section) for

both upright and suspended mounting. If it is mounted

horizontally, we recommend a suspension distance of

1.25 m (4 rail holders per 5 m rail).

Connectors for aluminium profile rails

Connectors are necessary for joining the aluminium

profile rails. Each connector (WCS-MC1) consists of two

flat aluminium pieces and four self tapping screws

(3 mm x 4.5 mm). The flat pieces are pushed into the

bottom grooves in the two profile rails to be joined, with

drillholes ahead. Then the screws will screwed into the

holes of the flat pieces (see drawing at left side). The tips

of the screwes will pressed into the aluminium profile and

fix the flat pieces in the grooves.

Stainless steel connectors are used for joining the pow-

der-coated aluminium profile rails (WCS-MC2).

Notes on installing the aluminium profile rail

When assembling the aluminium profile rails with the

connectors, it is important to leave a gap to compensa-

te for thermal expansion in case the temperature maxi-

mum operating temperature possible should be higher

than the temperature during installation. The gap width

necessary is calculated as follows:

Gap width in mm = 0,11 * Δϑ

Δϑ = max. ϑ

Examples:

Δϑ = 10 K, Gap width = 1,1 mm

Δϑ = 20 K, Gap width = 2,2 mm

Δϑ = 30 K, Gap width = 3,3 mm

Installing the code rail in the profile rail

First of all, the aluminium profile rail is attached to the

substructure using the rail holders and aligned. The

joints must be produced as described. Then the code

rail can be laid fully in the groove of the profile rail. The

code rail is ultimately fixed by means of a plastic cord

which is pressed into the groove of the profile rail. To

do so, the cord is pressed into the groove while simul-

taneously pressing down the code rail. Pressing it in

correctly is extremely important for reliable operation,

in particular if the aluminium profile system is suspen-

ded.

Installation of WCS2 code rail with aluminium profile system

Fitting tool

A special fitting tool is available for speedy and safe

installation of the code rail. The fitting tool is to be re-

commended particularly if the aluminium profile sy-

stem is suspended. The tool consists of a housing with

wheels similar to the guide trolley. The trolley is pulled

along the profile rail. The code rail is held in position

by the guide roller and pressure roller and the fixing

cord pressed into the groove of the aluminium profile

by the pressing wheel. Moving the trolley back and

forth ensures that the plastic cord sits in the groove

correctly (Fig. 10). If it is installed correctly, the pressu-

re of the fixing cord is only sufficient to prevent the

code rail slipping out of the aluminium profile even if it

is in a suspended position.

The seating of the plastic cord and the code rail should

be checked during maintenance, in particular if the

aluminium profile is suspended.

Fixed points

To prevent the aluminium profile rails slipping in the rail

holders when installed horizontally, a locking bracket is

necessary. The locking bracket (Fig. 11) is fitted

around a rail holder in the middle of the runway. Du-

ring installation, bracket and aluminium profile are

joined with the screw supplied. To do this, the alumini-

um profile must be drilled through at one point (drill

7 mm). If installed vertically, we recommend locking

the aluminium profile with a suitable support bracket

(by customer). To prevent the code rail slipping in the

aluminium profile, it can be fixed in the centre of the

runway by inserting a spring dowel pin or self-tapping

screw (Fig. 12).

Guide trolley

The guide trolley (Fig. 13 and 14) for the reading head

always ensures the optimum position of the reading

head in relation to the code rail. The mounting plate for

the reading head is already prefitted on the trolley so

that it only needs to be pushed on. By means of the

towing arm moving freely in the oblong hole of the

guide trolley (8 mm in diameter), on the one hand the

movement between vehicle and reading head is isola-

ted, and on the other hand mechanical tolerances are

equalised. When fitting the towing arm installed on the

conveyor vehicle, take care that no forces are exerted

(no rigid connection between towing arm and guide

trolley!) On the guide trolley holes are provided for

fitting the cleaning brushes for the code rail (WCS2-GT-

BR). The cleaning brushes (optional extra) are only ne-

cessary in extremely dusty ambiences (cement plants,

foundries) and can be retrofitted.

In such applications the use of the guide trolley with

steel wheels (WCS2-GT09-M1) is recommended. The

maximum velocity for the reading head with guide trolley

is 8 m/sec. The guide trolley is also available powder-

coated (WCS2-GT09-P1-C).

Grounding the aluminium profile system

We recommend making a low-ohm connection bet-

the beginning and end of the runway (Fig. 15)

Further information

Stainless steel or laminate code rails can be used with

the aluminium profile system. The laminate code rail

has proved to be suitable for normal industrial applica-

tions. In addition to cost advantages, the plastic lami-

nate code rail is of advantage during installation, in

particular on long runways, due to its lighter weight.

For extreme operating conditions, e. g. sparking in a

welding shop, severe dirt accumulation during operati-

on (e. g. waste incineration) or if cleaning brushes are

used on the guide trolley, we recommend using the

stainless steel code rail.

Pre-tensioning the code rail is not necessary for the

system functions. It is merely useful if high tempera-

ture fluctuations may occur within short periods of

time.

A special aluminium profile system has been developed

for the rapid installation of the 70 mm high WCS3 code

rail in plastic laminate or stainless steel. The aluminium

profile rail is designed to take the code rail. It has been

designed to provide optimum flexural strength in all direc-

tions in spite of its low weight. The aluminium profile

system can be fitted in any position. The profile rails are

supplied in 6 m sections. On request, the aluminium

profile rail can also be supplied powder-coated and in

curved sections.

Installing the aluminium profile rail

Rail holders, into which the profile rail is clipped, are

available for rapid installation of the aluminium profile rail.

The rail holders are available in two different versions:

the screw-on holder is bolted to the substructure, the

holder for installation in a C profile is designed for moun-

ting in a C profile rail (30 mm x 32 mm). The recom-

mended suspension distance for the aluminium profile

rail is 2.00 m (min. 3 rail holders per 6 m section), the

max. suspension distance is 2.50 m.

Connectors for aluminium profile rails

Connectors are necessary for joining the aluminium profi-

le rails. Each connector (WCS3-MC1) consists of a

170 mm long aluminium extruded section and two self-

tapping screws M3 x 4.5 mm. The connector is pushed

into the bottom grooves in the two profile rails to be joi-

ned. Then the screws are screwed into the holes

(1.8 mm in diameter). The tips of the screws are pres-

sed into the aluminium profile and hold the connector

down.

Notes on installing the aluminium profile rail

When assembling the aluminium profile rails with the

connectors, it is important to leave a gap to compensa-

te for thermal expansion. This is necessary if the maxi-

mum operating temperature possible should be grea-

ter than the temperature during installation. The gap

Δϑ = max. ϑ

installation

Examples:

Δϑ = 10 K, gap width = 1.2 mm

Δϑ = 20 K, gap width = 2.4 mm

Δϑ = 30 K, gap width = 3.6 mm

Installing the code rail in the profile rail

First of all, the aluminium profile rail is attached to the

substructure using the rail holders and aligned. The

joints must be produced as described. Then the code

rail can be laid fully in the groove of the profile rail. The

code rail is ultimately fixed by means of a plastic cord

which is pressed into the groove of the profile rail. To

do so, the cord is pressed into the groove while simul-

taneously pressing down the code rail. Pressing it in

correctly is extremely important for reliable operation,

in particular if the aluminium profile system is suspen-

ded.

Mounting tool

A special mounting tool is available for secure and

speedy attachment of the code rail. It is particularly

recommended if the aluminium profile system is sus-

pended. The tool consists of a wheeled housing. The

trolley is pulled over the profile rail, the code rail being

held in position by the guide roller and the fixing cord

pressed into the groove of the aluminium profile by the

pressing wheel. Moving the mounting trolley back and

forth ensures that the fixing cord lies correctly in the

groove of the aluminium profile (fig. 7). If fitted correct-

ly, the pressure from the fixing cord is sufficient to pre-

vent the code rail slipping out of the aluminium profile

even when suspended.

The seating of the fixing cord and cord rail must be

checked during maintenance, particularly if the alumi-

nium profile is suspended.

WCS3

Installation of WCS3 code rail with aluminium profile system

Fixed points

To prevent the aluminium profile rails slipping in the rail

holders when installed horizontally, the profile must be

firmly connected to the substructure. A rail holder in the

centre of the runway is rough-drilled on both sides with a

drilling 1.8 mm in diameter (fig. 8). Self-tapping screws

(3 x 6 mm) are screwed into these drillings. The self-

tapping screws are not supplied. The screws press into

the aluminium profile forming a keyed connection (fig. 9)

between rail holder and aluminium profile.

It is also possible to fix the aluminium profile as descri-

bed at several points along a runway. An adequate ex-

pansion joint between the aluminium profiles must be

ensured (see also page 21).

For vertical installation, we recommend securing the

aluminium profile with a suitable support bracket (to be

supplied by customer).

Vertical Bend

Beside horizontal bends, also vertical bends are needed,

to realize upward/downward gradients. With the help of

the aluminiumprofile rail, together with the laminate code

rail, vertical bends up to a minimum radius of 4 m can be

made very simply. For this, the aluminium profiles bent

with the appropriate radius are clipped into the rail hol-

ders. To ensure that the code rail can follow the vertical

course of the bend, a cut is made from the start of the

bend up to its end, in the distance of approx. 50 mm.

The cuts are always made from below, i. e. from the

wider side of the code rail until into the code windows

(see fig. 10). In addition, a small triangle is cut off with

every cut (see fig. 11). This prevents the code rail from

overlapping in the aluminium profile.

If the code rail was cut as described, it is inserted toge-

ther with the fixing cord and by means of the fitting tool

into the pre-curved aluminium profile.

Breaks in aluminium profile

For some applications, it may be necessary to interrupt

the code rail, e.g. for crane crossovers, fire doors or

large expansion joints in buildings. The break in the code

rail must be at least the length of a reading head (85 mm)

and the two code rail sections must be aligned. The ma-

ximum clearance between the end of an aluminium profile

rail and the next rail holder must not exceed 0.5 m.

Integrating WCS3 code rail into Vahle VKS 10 conductor line

Suspension of stainless steel code rail

When the stainless steel code rail is suspended, in

particular if there are frequent temperature fluctuati-

ons, it must be secured against falling. Using the ten-

sioning device is sufficient for lengths up to approx.

25 m. Above this, we recommend securing the stain-

less steel code rail in the aluminium profile every 12 m

with a self-tapping screw or a spring dowel pin. The

aluminium profile and the code rail are through-drilled

from the side (see fig. 13). Then the self-tapping screw

is screwed into this drilling (or the dowel pin pressed

in). The self-tapping screw or dowel pin are not supp-

lied.

Further information

The stainless steel or laminate code rails can both be

used with the WCS3 aluminium profile system. The

laminate code rail has proved to be suitable for normal

industrial applications. In addition to cost advantages,

the plastic laminate code rail is of advantage during

installation, in particular on long runways, due to its

lighter weight. With regard to operating conditions, the

same applies as for the WCS2 profile system (see

p. 16f.), with one exception: a guide trolley is not used

in conjunction with the WCS3 aluminium profile sy-

stem.

You will find further information and installation hints in

"WCS3 special aluminium profile system". This docu-

ment can be requested from us or downloaded from

our Internet home page.

Integrating WCS code rail into conductor lines

In many applications, energy is transmitted to a vehicle

by means of conductor lines. Users often request an

integrated solution for energy transmission and positio-

nal measurement. This demand has been taken into

account in developing the new Vahle VKS 10 conduc-

tor line. The VKS 10 is flexible as regards the number

and cross-sections of conductors and enables the

WCS code rail to be integrated economically into the

plastic base of the conductor line. It is preferable to

use the 70 mm high WCS3 laminate code rail. Special

holes for mounting, and thus a special code rail, is ne-

cessary for installing the WCS3 code rail in the VKS10

system (WCS3-CS70-L2).

The laminate code rail is characterised by high flexibility

and tear resistance. Reproducibility of location coordina-

tes is guaranteed by the use of the code rail, indepen-

dent of the ambient conditions. Reliable system

functions even in extremely harsh industrial ambiences

is guaranteed by the transmitted light process used on

the WCS.

You can obtain further information on the VKS 10 con-

ductor line system from the Vahle sales organisation.

RS 485 reading head

The reading head can be connected directly

to the control via a serial RS 485 interface. Various

data protocols and data transmission rates are

available. Up to four WCS2 and/or WCS3 reading

heads can be connected together in an RS 485

bus line. In this case, the reading heads must have

different bus addresses. The bus address for the

reading head, if it differs from the standard address

of 0, must be stated when ordering. The bus

address is included in the type designation of the

reading head (rating plate on reading head).

See also type summary page 70.

Response times

The minimum response time of the reading head

(start transmission of 1st data byte of response

telegram) is dependent on the internal time se-

quence of the reading head and is 10 ... 180 μsec

for data protocols 1 and 2.

For data protocol 3, the response time is one byte

time + 10 ... 100 μsec. The byte time is dependent

on the baud rate and is calculated from 1/baud

rate * 10,000 in μsec.

Example: 38.4 kBaud

byte time = 1/38.4 * 10,000 = 260.4 μsec.

In contrast to previous WCS reading heads, the A

types have no connection facility for the cable

shield, either on the plug connector or on the rea-

ding head housing. A low-resistance (wide area)

connection between the cable shield and the sy-

stem potential is made in the control panel. In the

case of high electromagnetic interference radiati-

on, it is recommended to make a low-resistance

connection between the shield of the data cable

and the system potential by an earthing clamp in

the direct vicinity of the reading head.

SSI data format

The reading head with SSI interface corresponds as

to its data format to a 25 bit absolute value encoder

with 4096 revolutions and 4096 increments per revo-

lution. The WCS reading head effectively supplies a

maximum of 512 revolutions and 1024 increments

per revolution.

col. See also page 30, Detection of dirt accumulati-

on.

Note

Due to the edge-triggered data transmission the SSI

interface is more vulnerable than asynchronous data

transmission procedures. In the case of festoon

cables or long cable lengths (> 12 m) between SSI

reading head and control, we therefore recommend

using the SSI interface module. In this case the

data are transmitted asynchronously from the rea-

ding head to the interface module via the RS 485

interface and converted to the SSI protocol directly

next to the control. Further advantages of the inter-

face module with SSI interface are the positional

value display and the possibility of reading head

diagnosis (see also p. 36f).

Features and options

WCS2AWCS3A

Detection of dirt accumulation

The new generation reading heads, WCS2A and

WCS3A, continuously check the condition of the

optics. If the light output of the infrared transmitter

is reduced, e. g. due to dirt accumulation on the

transparent liners, the reading head automatically

increases the light intensity. If too much dirt accu-

mulates, a warning signal is transmitted to the pri-

mary control (diagnosis bit DB=1). The automatic

light adjustment in the reading head provides ade-

quate time to clean the reading head during the

next maintenance.

The condition "dirt accumulation detected" is also

signalled optically on the WCS3A reading head -

the yellow and red LEDs on the face of the reading

head flash alternately.

In order to clean the optics, the reading head must

be removed from the code rail (pulled off the

mounting plate). After cleaning the transparent

liners, the dirt accumulation signal is automatically

deleted by the reading head. If the signal is not

deleted in spite of careful cleaning or replacement

of the plastic liners, the optoelectronics may be

damaged. In this case the reading head must be

sent for inspection.

be equipped optionally with space heating. The

heating is powered by the voltage supply of the

reading head, i. e. no additional plug connection is

necessary for the space heating. The cross-section

of the supply cable to the reading head must be

suitably dimensioned (see also data cable, page 66).

The space heating is switched on immediately when

the voltage is connected to the reading head, the po-

wer consumption is 7 VA. The space heating option

permits the reading head to be used in temperature

range from -40 °C ... 60 °C.

Option S - velocity output

(WCS3A only), S

On the WCS3A reading head with velocity output,

exceeding a limit velocity is signalled via an addi-

tional 24 V DC output. The limit velocity can be

configured on the 4-fold DIP switch in the reading

head. Unless ordered differently, the limit velocity

is set to 0.7 m/sec on delivery.

The digital output, protected against open circuit, is

via Pin 4 (s. Fig. 1) of the 9-pole Sub-D plug con-

nector:

Operating voltage of interface module

The operating voltage (24 V DC ± 10%) for the

interface module is connected to terminals UB+

and GND.

Connection of reading heads

The voltage supply for the reading heads is con-

nected to the terminals SUB and GND lying on a

terminal strip. The output for the supply voltage of

the reading heads corresponds to the supply volta-

ge, however it is protected in the device by a fuse

(short-circuit protection for reading head). The

miniature fuse (5 mm x 20 mm, 1 A quick-blow) is

designed for a connected load of max. 20 VA. If

more than two WCS2 reading heads with the hea-

ting option (9 VA load) are connected, the supply

voltage for the reading heads must be tapped from

the operating voltage terminal of the interface mo-

dule.

The RS 485 data cable to the reading heads is

connected to terminals SDA and SDB.

Connection to control

The positional value is transmitted to the control

via 19 digital outputs (P00 ... P18).

The 24 V DC outputs of the interface module

function as a push-pull output stage (driver capaci-

ty 15 mA) and are connected directly to a corre-

sponding I/O unit in the control. P00 is the least

significant bit (LSB) and P18 the most significant

bit (MSB) of the output word. The maximum posi-

tional value in the individual application depends

on the length and coding of the code rail.

Example: The code rail begins at position 0 (stan-

dard) and is 50 m long. Then the highest positional

value is for

WCS2: 50 m x 1,200 Pos/m = 60,000

WCS3: 50 m x 1,250 Pos/m = 62,500

In this example, only 16 outputs P00 ... P15

(= max. 65535) are required.

50 m

WCS2: 50 m x 1,200 Pos/m = 60,000

WCS3: 50 m x 1,250 Pos/m = 62,500

= max. 65535

WCS-IP110 - parallel interface

Error bit (ERR)

If an error is detected in the WCS system, it is

transmitted to the control as follows:

ERR=1

P00 ... P04=error code (see p. 61)

The error is present at the outputs for at least

50 ms. With a module set to Gray code (WCS-

IP1.1), the error code is also output in Gray code.

Reading head outside code rail

If the reading head leaves the code rail, the control

receives a specified bit pattern.

ERR=0

P00 ... P18=1 (positional value = 524287)

With a module set to Gray code, this positional

value is also output in Gray code.

Address lines (A01 and A00)

If several reading heads are operated on one inter-

face module, the reading head whose data are to

be transmitted to the outputs must be selected via

the two address inputs. If only one reading head

(with address 0) is connected to the interface mou-

le the address inputs are not connected. After the

address lines have been activated, the interface

module requires a maximum of 1.5 ms until the

positional value for the reading head selected is

present at the interface.

Store bit (STO)

Input for storing the outputs of the interface modu-

le. A "1" means that the outputs are no longer

being changed, "0" means that the outputs are

actualised in a 1 ms-cycle. The store signal is acti-

ve immediately, i. e. the outputs are no longer ac-

tualised after the interface module has detected

the signal at the input. Data exchange with the

primary control can be synchronised by means of

the store signal.

Notes on programming an SPC

In order to ensure that the WCS positional values

are read in without errors, take note of the follo-

wing:

several reading heads are connected)

Display and diagnosis function of the interface

module

The interface module is equipped with a 6-digit 7-

segment display (LED) for visual display of the

reading head data. The 16-digit rotary switch (on

the right of the display) is used to select the rea-

ding head whose data are to be displayed. The

output via the interface is independent of this. A

further 7-segment display (to the right of the

switch) shows the current position of the switch

(function number). If the function is unknown, "----"

appears in the left-hand display.

Error code

If the interface module detects a misfunction of the

reading head or an internal fault, an error code is

transmitted on the display (e. g. "Err 13") and si-

multaneously transmitted to the control via the

interface. With the aid of the error code, the cause

of the fault can be speedily ascertained and elimi-

nated. (See also p. 61).

Reading head diagnosis

The WCS3A reading heads continuously perform a

self-diagnosis. If dirt accumulation on the reading

head is detected, '-bad-' is shown cyclically on the

display, the relevant reading head address (0 ... 3)

is shown on the right next to the rotary switch on

the display. In addition, the reading head can be

requested to perform a diagnosis (see table abo-

ve).

During the diagnosis, the reading head must be

outside the code rail, for this period an error signal

is output at the parallel interface for the correspon-

ding reading head. The diagnosis result is shown

on the display.

WCS-PG210 - Profibus DP

1.5 mm

WCS-PG210 - Profibus DP interface

The device has two cable lugs for connecting the

protective earth. The protective earth must be con-

nected to these cable lugs with a wire cross-sec-

tion of at least 1.5 mm

Operating voltage of interface module

The operating voltage (24 V DC ± 10%) for the

interface module is connected to terminals 1 and 2

of the 5-pole push-lock terminal. When the opera-

ting voltage is connected correctly, the green "Po-

wer" LED must be illuminated.

Connection of reading heads

The voltage supply for the reading heads is con-

nected to screw terminals 1 and 2 of the plug con-

nector (same terminals as for connection of opera-

ting voltage).

The RS 485 data lines to the reading heads are

connected to terminals 3 and 4. The "Interface"

sliding switch must always be set to position "485".

If the module is at the beginning or end of the data

line to the reading heads, the RS 485 terminating

resistor must be activated. To do so, set the sliding

switch "RS485-Termination" to "On". If only one

reading head is connected to the PG210, this

switch must always be set to "On".

Connection to control

The connection to the Profibus DP is via a 9-pole

plug connector as per Profibus norm. For this, a 9-

pole Sub-D plug is required which is plugged into

the 9-pole Sub-D socket on the device. This plug is

not part of the supply of the interface module. The

Profibus address (in hex code) is set with the two

rotary switches "Profibus-ID" "High" and "Low".

Example: Address 19 (=13h): High = 1, Low = 3.

The terminating resistor in the Profibus can be

switched on ("On") or off ("Off") with the "Terminati-

on" sliding switch.

Profibus diagnosis

In addition to the standard diagnosis data (6 by-

tes), a device-specific diagnosis of the PG210 is

supported. The length of the specific diagnosis

data is 1 byte, giving a maximum length of the

diagnosis data of 8 bytes. If an error or warning is

present, the corresponding code is transmitted via

the diagnosis byte. This code is also shown via the

4 LEDs "Error No/Select ID" when the red state

LED is illuminated, i. e. the content of the diagno-

sis byte is a replica of the LED display.

Operating voltage of interface module

The operating voltage (24 V DC ± 10%) for the

interface module is connected to terminals 1 and 2

of the 5-pole push-lock terminal X1. When the ope-

rating voltage is connected correctly, the green

"Power" LED is illuminated.

Connection of reading heads

The voltage supply for the reading heads is con-

nected to screw terminals 1 and 2 of the 5-pole

necting the operating voltage).

The RS 485 data lines to the reading heads are

connected to terminals X1-3 and X1-4.

The sliding switch "Interface" must always be set

to position "485".

If the module is at the beginning or end of the data

line to the reading heads, the RS 485 terminating

resistor must be activated. To do so, set the sliding

switch "RS485-Termination" to "On". If only one

reading head is connected to the DG210, this

switch must always be set to "On".

The number of reading heads connected is set

Data exchange in the DeviceNet

The DG210 acts as "Group 2 Only Slave" in the

DeviceNet. The access procedures "Polling," "Bit-

Strobe" and "Change of state" are supported. If

more than two reading heads are connected to the

DG210, the data can only be interrogated via pol-

ling access. Transmitting a function byte also is

only possible in polling mode.

Polling

In polling, a function byte is transmitted to the

DG210 by the master. The DG210 then returns 16

data bytes. The 16 bytes contain the data of the 4

reading heads (4 x 4 bytes). If less than 4 reading

heads are configured (via rotary switch S4), the

four data bytes for the unconfigured reading heads

contain the value 0x00.

Bit-strobe

With bit-strobe access, the command "bit-strobe" is

transmitted by the master without any further data.

The master then always receives 8 data bytes as a

response from the interface module. The 8 data

bytes contain the data of the reading heads with

address 0 and 1 (2 x 4 bytes). If the reading head

with address 1 is not connected (rotary switch S4

is in position 1), the 4 dta bytes for this reading

head are 0x00.

Change of state

In this procedure, the DG210 transmits 8 data by-

tes to the master without being requested as soon

as the content of the data is changed. The data

format corresponds to that for bit-strobe access.

If the data of the reading heads change constantly,

e. g. if the reading head is travelling fast, the data

are transmitted every 5 ms. In this case the rest

time is necessary to avoid overloading the Device-

Net bus.

WCS-CG210 - CANopen interface

Interface module with CANopen interface

The WCS-CG210 acts as interface between the

WCS reading head and the CAN-Bus. The data

are transmitted between the reading head(s) and

the CG210 via the RS 485 interface and from the

CG210 to the control via the CANopen protocol. A

maximum of four WCS2 and/or WCS3 reading

heads of type LS221 (or LS121) can be connec-

ted. If several reading heads are connected, they

must have different addresses. The interface mo-

dule CG210 functions as CANopen slave in the

"predefined connection set" and permits data

transmission rates up to 1 MBaud.

WCS-CG210 - CANopen

± 10%

24 V DC

WCS-CG210 - CANopen interface

Operating voltage of interface module

The operating voltage (24 V DC ± 10%) for the

interface module is connected to terminals 1 and 2

of the 5-pole push-lock terminal. When the opera-

ting voltage is connected correctly, the green "Po-

wer" LED is illuminated.

Connection of reading heads

The voltage supply for the reading heads is con-

nected to screw terminals 1 and 2 of the 5-pole

push-lock terminal (same terminals as for connec-

ting the operating voltage).

The RS 485 data lines to the reading heads are

connected to terminals 3 and 4.

The number of reading heads connected is set

with the rotary switch S4. The position of the

switch simultaneously presets the baud rates:

1:1 head(addr.0)-BD-Set A

2:2 heads(addr. 0,1)-BD-Set A

3:3 heads(addr. 0,1,2)-BD-Set A

4:4 heads(addr. 0,1,2,3)-BD-Set A

5:1 head(addr. 0)-BD-Set B

6:2 heads(addr. 0, 1)-BD-Set B

7:3 heads(addr. 0, 1, 2)-BD-Set B

8:4 heads(addr. 0,1,2,3)-BD-Set B

The sliding switch "Interface" must always be set

to the position "485".

If the module is at the beginning or end of the data

line to the reading heads, the RS 485 terminating

resistor must be activated. To do so, set the sliding

switch "RS485-Termination" to "On". If only one

reading head is connected to the CG210, this

switch must always be set to "On".

Transmission type

As per CANopen specification, the transmission

type can be configured in the CG210. After swit-

ching on the device the following transmission type

is preconfigured:

S5 = 0...B, E and F: asynchronous

In this mode the CG210 transmits data automati-

cally if the data of the reading head change, howe-

ver minimum every 3 ... 250 ms (can bei set with

rotary switch S5, see table). This prevents the CA-

Nopen Bus being overloaded in the case of conti-

nuous changes in the WCS data. With asynchro-

nous transmission, if there is no change in the

reading head data, i.e. vehicle is stopped, no furt-

her data are transmitted. By selecting S5=E / F the

data will be transmitted max. every 3ms / 5ms,

however minimum every 50 ms / 20 ms. Thus the

control receives data even when the vehicle is at a

standstill.

S5 = D: cyclic synchronous

The CG210 transmits data after receiving the

SYNC command. If one or two reading heads are

connected PDO1 is transmitted, if more then two

reading heads PDO1 and PDO2. The typical re-

sponse time after SYNC is 2 ms, the maximum

response time is 5 ms.

required which is plugged into the 9-pole Sub-D

plug in the device. This socket is not part of the

supply of the interface module. The module ID of

the CANopen address is set via the 6-pole DIP

switch "Node ID" (the most significant bit of the 7-

digit module ID is "0").

Node-ID "0" is not permissible.

The terminating resistor in the CANopen bus can

be switched on ("On") or off ("Off") with the sliding

switch "Termination".

Data exchange in the CANopen bus

The CG210 functions as CANopen slave in the

"predefined connection set". 5 objects are defined

WCS IG110 - InterBus-S interface

Interface module with InterBus-S interface

The interface module acts as interface between

the WCS reading head and the InterBus-S (Inter-

bus-S remote bus). The data are transmitted bet-

ween the reading head(s) and the interface modu-

le serially (with RS 485 interface) and from the

interface module to the control via InterBus-S pro-

tocol.

One or two reading heads type LS221 (or LS121)

can be connected.

Connecting more than two reading heads (max. 4)

is possible on request. The data can be transmit-

ted in binary or Gray code.

The data are transmitted with 500 kBaud in Inter-

Bus-S. The data communication with 2 MBaud is

possible on request.

WCS-DDM1

WCS-DDM1 Display and diagnosis module

Function

The display module is used for the display and

extended diagnosis of WCS reading head data. It

is connected to the reading head(s) and passively

logs the data communication between the reading

head(s) and the control or the interface module. In

addition to the current positional value of the rea-

ding head(s) other diagnostic data can be display-

ed on the six-figure seven-segment display. The

data are called up by means of the hex rotary

switch next to the display.

Connection to reading head data line

Normally voltage (24 VDC ±10%) is supplied to the

display module via terminals UB+ and GND. The

module is protected against short circuits by an

internal miniature fuse (F 500 mA), its power input

is 2 VA.

The data signal from/to the reading heads is con-

nected to terminals SDA and SDB. Alternatively

the display module can be connected to the volta-

ge supply of the reading heads via terminals SUB

and GND. However the module is then not protec-

ted against short circuits.

Display functions

The display module has three display modes which

can be selected automatically dependent upon

number and type of reading heads connected:

•Display mode 1:

4 reading heads with 3 diagnostic values each

•Display mode 2:

max. 3 reading heads with 4 diagnostic values

each (standard mode)

•Display mode 3:

only if reading heads (max. 2) with extended

data protocol 3 are connected

The individual diagnostic values such as current

position, highest priority error, time of error signal

and last valid position when error occurred (not in

display mode 1) can be called up for each reading

head connected. When the display module is swit-

ched on, first a functional test is performed (all

segments illuminated), then the reading head type

(e. g. ‘LS211’) and finally the device code are dis-

played. Then the display changes to the value set

by the rotary switch. The current switch position is

shown on the seven-segment display to the right of

the rotary switch.

Display modes

-Display mode 2 is selected as standard when

module is switched on

-As soon as a reading head with address 3 is

detected, module switches over to display mode

1 which is maintained until it is rebooted

-Display mode 3 is only activated if a reading

head with extended data protocol 3 is detected

„OUT“

„BAD“

Significance of displays

-Data:

If the reading head is on the code rail and no

error occurs, the current positional value is dis-

played, otherwise „OUT“ or the error number.

If the module detects that a reading head’s optics

are dirty, the signal „BAD“ flashes cyclically in the

display with a full stop after the displayed value.

„OUT“

-Error:

If an error occurs, the error with the lowest error

number is stored and displayed, i. e. if for ex-

ample error 13 should occur after error 1, error 1

will continue to be displayed with the correspon-

ding time and position (no position in mode 1)

and error 13 is ignored. Conversely error 13 is

overwritten by a subsequent error 1 (also time

and position if applicable). The „OUT“ signal has

the lowest priority.

- System error:

If a system error has occurred in the display mo-

dule, its error number and the time of its occur-

rence are stored and output. System errors have

error numbers > 20.

WCS-DDM1 Display and diagnosis module

-Toogle Info:

The display alternates (every 3 sec) between

reading head type (e. g. „LS221“) and time, first

in format „hh:mm:ss“ and then

in format „dd:hh:mm:“.

The highest bus address detected is displayed in

the single-figure seven-segment display to the

right of the rotary switch. If bus address 3 is dis-

played, 4 reading heads are connected and the

display module is in mode 1.

-Speed:

In display mode 3, the current speed of the rea-

ding heads is output in addition to the diagnostic

values mentioned above. The display range co-

vers 0.0 to 12.5 m/s. Value „12.7“ signifies:

„unknown speed“. If the value displayed is prece-

ded by an „L“, the last valid speed of the reading

head is output, as the current value is unknown

(e. g. reading head outside code rail).

-Delete error memory (switch position F):

The display flashes for 5 sec, then the error me-

mory is deleted.

Supplementary function error counters

The error counters for reading heads with address

0 and 1 can be called up by connecting inputs A00,

A01. The error counter for the reading head with

address 0 is called up by applying the operating

voltage (+24 V DC) to A00, and the error counter

for the reading head with address 1 by applying

the operating voltage to A01. Inputs A00 and A01

have higher priority than the rotary switch, i.e. if

the operating voltage is applied to input A00 the

display changes to the error counter of the reading

head with address 0. Input A00 has highest priority

and asserts its display even if operating voltage is

present at A01. The maximum value of the error

counters is 65535. An existing error is only counted

once. If the „OUT“ signal is interpreted as an error

(see page 59 - DIP switch S3) it is included in the

count. The error counters are reset when the error

memory is deleted.

Functions of internal DIP switches

The WCS-DDM1 display module is adapted to the

reading heads to be monitored by means of the

internal DIP switches. The display module must be

opened to do so. Unscrew the outer four screws

(Fig. 1A) on the box terminal blocks and remove

the terminal blocks. Then unlock the housing cover

with the display board at the side with the aid of a

screwdriver and remove it (see Fig. 1B). Now the

boards can be removed. The DIP switches are on

DIP switch S3 - selection of reading head type

The display module must be set to the correct

baud rate and data protocol to permit a certain

reading head type to be monitored.

The baud rate is set by means of switches 1 ... 3

and the data protocol by switches 4 ... 6. Switch 7

determines whether the OUT signal (reading head

outside code rail) is regarded as an error or not.

Switch 8 is without function.

Example:

SwitchS3 - 1 = ON, 2 = ON, 3 = OFF, 4 = ON,

5 = OFF, 6 = OFF,7 = ON, 8 = OFF,

signifies that the display module is set to baud rate

19.2 kbaud and protocol 3 (reading head type

LS246 or LS146). „OUT“ is not treated as an error.

The possible settings are described in detail in the

following tables.

The reading head can be requested to perform a

request byte. The reading head must be outside

the code rail. On the new generation reading head

types (WCS2A, WCS3A), the degree of dirt accu-

mulation on the optical unit is monitored automati-

cally during operation and the diagnosis bit (DB)

set if dirt accumulation is too high. Thus the speci-

fic request for diagnosis to the reading head via F0

in the request byte is no longer necessary. Howe-

ver for reasons of downwards compatibility this

function is also supported by the new reading

heads.

ERR and OUT signal

OUT signal

The "OUT" signal may be desired and correct,

e. g. if the code rail is interrupted and the WCS (or

the reading head) transmits this information bet-

ween the separate rail sections to the control.

However if the "OUT" signal should not appear, the

following test steps must be carried out:

Remedy

- Align code rail exactly

- Align reading head

- Use guide system for reading head

- Clean optical unit

- Use cleaning system for reading head

- Replace plastic linings

- Protect reading head from external light

WCS

Connection of RS 485 reading heads to inter-

face moule/control

The RS 485 interface which permits several end-

of-line devices to be interconnected via a bus line

has proven extremely successful in practice. Due

to its reliability, it is used with many bus systems

such as Profibus. In the WCS system, the RS 485

interface is used for data communication between

reading head and control. Also when Stahltronic

interface modules are used, data transmission

between the reading heads and the interface mo-

dule takes place via an RS 485 interface.

Reading head addresses

If several devices are interconnected in a bus, the

bus users must have different addresses. The data

in the bus can then be clearly assigned by means

of the relevant bus address. The WCS bus is desi-

gned in such a way that the control or interface

module functions as a master. The WCS reading

heads are slave users and are interrogated (pol-

led) cyclically by the master.

If only one reading head is connected to the con-

trol or interface module, this reading head always

receives the address 0. A maximum of four WCS

reading heads (addresses 0 ... 3) can be connec-

ted to an interface module or an RS 485 interface

of the control via an RS 485 bus line.

The reading head is available with four different

addresses. The reading head address is included

in the type designation (see also p. 70). WCS2 and

WCS3 reading heads can be connected in one bus

line.

Example:

LS221-0: Reading head with address 0

LS221-1: Reading head with address 1

If the address is not clearly stated, e. g. LS221,

this is synonymous with address 0. The master

does not require an address of its own, however it

must know the number of reading heads connec-

ted. On this point, see the description of the rele-

vant interface module.

Information and installation hints for configuration of

the reading head address can be requested from us

or downloaded from our Internet home page.

Cable routing in the RS 485 bus

The data cable must be installed in such a way

that an in-line connection always results between

the first and the last bus user. This in-line connec-

tion must be terminated at the beginning and the

end by a terminating resistor (resistance value:

120 ... 150 Ohm).

The RS 485 terminating resistors are integrated

into the WCS reading heads and the WCS inter-

face modules and can be activated or deactivated.

In the case of interface modules with field bus in-

terface (Profibus, DeviceNet, CANopen), the termi-

nating resistor can be activated or deactivated

from outside. This is not possible in the case of the

interface module with parallel interface and the

WCS reading heads due to the type of housing

and protection class. Thus when ordering, it must

be stated whether the device is to be supplied with

or without RS 485 terminating resistor.

In the simplest case, only one reading head is

connected to the control or the interface module. In

this case, there is one device at the beginning and

one device at the end of the data line. The RS 485

terminating resistor is activated on both devices.

If two reading heads are connected to a serial

communication channel or interface module, two

wiring versions are possible:

a)The RS 485 terminating resistor is activated on

both reading heads. In this case there is a rea-

ding head both at the beginning and the end of

the data line, the interface module is in bet-

ween. It has no terminating resistor. In this versi-

on, each reading head is connected to the inter-

face module with a separate data cable.

b)The interface module is at the beginning of the

data line, with the RS 485 terminating resistor

activated. The RS 485 terminating resistor is

also activated on the reading head at the end of

the data line. The second reading head has no

terminating resistor. It is connected to the in-line

connection between the interface module and

the first reading head with a short spur line

(length <1 m). The BT111 bus terminal is used

to connect the spur line (see p. 65).

The decision as to which of the wiring versions is

more suitable must be taken dependent on the

individual application.

If three or four reading heads are used on the

same interface module, they must be connected

nection via spur lines (as in version b).

Example

RS 485

1)The longitudinal and vertical travel of a transport

vehicle is to be measured.

The control and the interface module are on the

vehicle, i. e. the control travels together with the

vehicle. The length of the data cable between

the reading heads and the interface module is

relatively short. In this case it is an advantage to

connect each reading head to the interface mo-

dule with a separate data cable. Both reading

heads are equipped with RS 485 terminating

resistors, the interface module has no resistor

(version a).

2)On a crane, the travel along the crane runway

and the crane bridge is to be measured. The

control and the interface module are in a control

centre, i. e. the control is stationary. The di-

stance between the interface module and the

reading heads is great. In this application, it is

advisable to connect both reading heads to the

interface module with one data cable. The rea-

ding head on the crane bridge and the interface

module are equipped with the RS 485 termina-

ting resistor. The second reading head on the

crane runway has no terminating resistor. It is

connected to the data cable via a short spur line

(version b).

BT111 bus terminal

The bus terminal is used as terminal connection

when a reading head is connected to the RS 485

data line via a spur line (see also p. 63).

It can also be used to reduce the cross-section of

data cables, e. g. if due to the diameter of a cable

(festoon cable) it is not possible to connect the

reading head directly to the incoming data cable.

The bus terminal provides an optimum connection

of the data lines and the shielding so that reliable

data transmission is always ensured.

The PG glands on the bus terminal are suitable for

cable diameters of 5 ... 9 mm.

Data cables

RS 485

RS 485 data cable

A 4-wire paired shielded data cable must be used

for the RS 485 data transmission. One pair of wi-

res is used for the supply voltage and one pair for

the RS 485 data connection.

The maximum length of the cable depends on the

one hand on the capacity of the data cable (wire to

wire) for data transmission, on the other hand on

the cross-section of the cables for the voltage sup-

ply of the reading heads.

A small wire cross-section and thus a low cable

capacity is an advantage for data transmission,

however for the voltage supply as great a cross-

section as possible is desirable. The table below

illustrates the cable lengths possible dependent on

the cable cross-section.

The calculations are based on the most unfavoura-

ble case: All the reading heads are at the end of

the data line. In the case of long cable lengths and

if several WCS2 reading heads with heating facility

are connected, 6-wire data cables (3 x 2) can be

used. In this case, two pairs are used for voltage

supply (doubling the cable cross-section) and one

pair for the RS 485 data line.

The table on the left shows the cable lengths pos-

sible dependent on the cable capacity (wire to

wire). The number of reading heads connected is

immaterial.

SSI data cable

A 6-wire shielded data cable (3 x 2, paired) must

be used for SSI data transmission. One pair of

wires is used for the supply voltage, one pair for

the CLK and one pair for the DATA data line. The

cable lengths technically possible can be seen

from the table. In the case of long cable lengths

(above 12 m) between SSI reading head and con-

trol, we recommend using the SSI interface modu-

le. In this case the data are transmitted asynchro-

nously via the RS 485 interface from the reading

head to the interface module, conversion to SSI

protocol takes place immediately adjacent to the

control (see also p. 36f.)

Cable installation

The precondition for trouble-free data transmission

is that the data cables are installed in such a way

as to prevent interference from electromagnetic

fields and other disturbances. In order to install the

cables to ensure EMC, it is necessary to divide

them into groups and install these groups separa-

tely.

Shielding cables

Shielding is a means of reducing electromagnetic

interference. To prevent these error currents them-

selves becoming a source of interference, a low-

ohm or low-impedance connection to the protecti-

ve earth is particularly important. Use only cables

with a braided shield (avoid foil shields). The shield

is brought into contact on both sides, i. e. in the

panel box and on the reading head (via the cable

lug on the reading head housing).

In exceptional cases, connecting the shield on one

side only may be better, if

-no equipotential cable is or can be installed

and/or

-a foil shield is used.

The following points must also be observed for

shielding:

-Use metal cable clips which enclose the shield

over a large area.

-Bring the cable shield into contact with the earth

bar immediately after its entry into the panel box.

-Lead protective earth connections to a point in

star form

-Use the largest cable cross-sections possible for

grounding.

Notes for use

Break in code rail

The WCS principle permits a break in the code rail.

A minimum gap of 85 mm between two code rail

sections must be observed.

The reading head recognises that it is leaving the

code rail and signals "OUT" to the control.

Due to the length of the reading head, the total

width of the OUT window is:

B = A + 160 mm

Replacing a code rail

If a code rail is bent or destroyed, it can be reme-

died as follows: Try to bend the code rail back into

shape. Make sure that the reading head does not

brush against the code rail when travelling over

this section.

If it is not possible to bend the code rail back into

shape, the complete rail or a section of it must be

replaced. On short runways, it is preferable to re-

place the complete code rail, on longer runways it

is possible to replace the damaged section only.

Calculate the beginning and end position of the

code rail to be replaced. The section of code rail is

ordered stating these two positional values and the

type of code rail (WCS2, WCS3, stainless steel,

laminate, height).

Replacing the complete code rail

The method of replacing the code rail is analogous

to that for initial installation. To avoid having to

reprogram the stopping positions in the control, the

following sequence is to be recommended:

reading head to a defined position, fix it in

position and read positional value

code rail

code rail and move it until the reading

head signals the same position to the control as

for the old code rail.

the code rail in position

Replacing a section

If a section is replaced, the replacement section

must overlap the installed code rail at the begin-

ning and the end by approx. 10 cm. This additional

length at the beginning and the end must be taken

into account when calculating the beginning and

end position of the code rail to be replaced.

Cut out the faulty section of code rail. Place the

replacement section onto the code rail so that the

code pattern of both rails matches.

Join the replacement section to the existing code

rail.

Recommended method of joining the code rails:

Stainless steel:spot welding, riveting

Laminate:riveting, stapling

Notes for use

WCS

WCS2

Difficult ambient conditions

The WCS scans the code rail opto-electronically.

The optical system prevents use in paint cabins or

in installations with water vapour or spray. Howe-

ver the WCS2 has proved successful in dusty am-

biences (e. g. foundries). In these ambiences, we

recommend using the WCS2 reading head with

the aluminium profile system (see p. 18ff.). The

WCS2 reading head is less sensitive to dirt than

the WCS3 reading head due to the smaller reading

gap. The WCS2 reading head will receive additio-

nal protection from being installed in a guide trol-

ley. As an option, brushes for cleaning the code rail

may also be attached to the guide trolley.

Cleaning the reading head

The quick-action lock on the mounting plate ena-

bles the reading head to be removed within a few

seconds. After removal, the transparent protective

liners which protect the reading area of the reading

head are cleaned using a clean cotton rag. If they

are very soiled, the liners can also be easily remo-

ved and cleaned with warm water

(if necessary with the addition of washing-up li-

quid). If the surface is scratched, the protective

liners must be replaced (see also page 11).

Outdoor use

For WCS applications in the open air we recom-

mend the WCS2 system:

-Use of the WCS2 reading head with space hea-

ting facility

-Installing code rail with aluminium profile system

(see p. 16ff.)

-Aluminium profile system suspended, i. e. code

rail points downwards (any dirt falls downwards)

-Use of stainless steel code rail (increased tempe-

rature range of stainless steel code rail)

-Guide trolley with cleaning brush option (additio-

nal enclosure for reading head and code rail cle-

aned if it should become soiled) and steel wheels

-Instal WCS system in a sheltered position or

protect with a suitable roof (do not instal on wea-

ther side, rain or snow must not enter gap in rea-

ding head)
