Removal / Installation
LB Type 2
➢ Remove the two screws (1) of the respective sensor (transmitter or receiver) to the mounting
bracket (2).
➢ Loosen the screws on the cable clamp (3) and unthread the fibre optic cable.
➢ Remove the black plastic guide from the left side of the feed axis, so that the connectors and
cables can be threaded in and out.
➢ Remove the cover from the feed axis .
The control units of the three light sensors are located under this cover (4), snapped on a
DIN rail.
In the control units there are 2 different part numbers.
If several of these units used, as always a master unit must be present:
"Fiber-optic sensor WLL180T-M vorprog Sxa" [03093294-01]
The "Follow-units" are plugged into the master unit and each "Follow-unit" can turn another
are infected.
"Fiber-optic sensor WLL180T-F vorprog Sxa" [03093295-01]
➢ The 2 pieces " Fiber-optic sensor WLL180T for the LS TYPE 2 in the NSM module are
located in the control rack of the WPC , snapped on a newly added top hat rail.
➢ From the control unit, the connecting cable is going down to the terminal block on the
backplane of the control slot, via a round plug.
NOTICE
Change of a control unit
The default setting of a new control unit is set to "D on" (Dark on), means active with an interrupted light beam.
However, for the WPC "L on" (Light on), means active with non-interrupted light beam, is required. .
When replacing a controller, therefore, the following settings must be made:
➢ Press Mode button for 3 sec.,
➢ Press Mode again, „d on“ is flashing,
➢ Switch to „L on“ with right cursor,
➢ Press Mode again,
➢ Restart the WPC.

➢ Connect the optical fiber at the corresponding control unit.
With the accompanying cutting tool in the spare part „Fibre optic cable LL3-TV05 2m“
[03092407-xx] you can cut the light guide to the required length.
➢ Mount the new fbre optic cable onto the mounting bracket (2 on 3).
➢ Align the sensor parallel to the mounting bracket (2).
➢ Move the „Jig for WPC4-6 base plate“ [03073064-01] with the corresponding mounting aid to
the position, where the Light barrier has to be made on.
➢ Place the sensor only slightly to the mounting aid and tighten the screw for mounting the
angle at the WPC manually first, so that they can adjust as the adjustments even then.
NOTICE
Labeling
The fibre optic cables are equipped from the factory with a label.
Take this labeling from the old fibre optic cable and put it onto the new one!
The labeling is about:
LA-h and LA-m for the Loading Axis; FA-n, FA-m, FA-h for the Feed Axis.
NOTICE
Use of the mounting aids
Place the corresponding light barrier from the top onto the corresponding step of the aid.
Take care, that the mounting aid is laying flat on the base plate.
The ”mounting aid WPC6 HC cpl.”
[03110969-xx] has pins on one side for
positioning on the base plate.
It can be placed thus, in 2 different
orientations on the base plate.
The different heights are labeled directly
beside the corresponding step on the jig

Settings
➢ Set the crash light barriers. See "3.7.7
Adjusting the Crash Light Barriers for Component height
"
[➙ 3-91].
NOTICE
Notice the direction of the light beam in the NSM module
In NSM module (at the loading axis) for the standard BE-height (15mm), a light barrier LS TYPE 1 is used.
The recipient of this photocell is on the left side (as seen in the direction to the feed axis).
When mounting the other two BE-heights (32 and 35, or 45mm) from the LS TYPE 2, attention must be paid to
the direction of the light beam. The light output has to be on the left side as well, so that the light beam can not
interfere with the recipient of the BE-height 15mm (LS TYPE 1).
You can simply swap the two fibre optic cables on the control unit if you need to change the light’s direction.
