5.5 Light barriers
WARNING
You may only check and calibrate the light barriers of the feed axis with the correct zero positions,
transfer positions and removal positions of the lifting and feed axes.

5.5.1 Tools and accessories
– Adjustment gauge, order no. 03021679-01
– 1 set of hexagon socket wrenches
NOTE
The Adjustment gauge for the light barriers are used differently for tower 1 and tower 2.:
At tower 2 the gauge is put onto the feed axis:
at gauge level 11.5 mm the light barrier must be activated,
at gauge level 11.4 mm the light barrier must not be activated.
at tower 1 the gauge is turned by 90 degrees and put onto the tray:
at gauge level 9.85 mm the light barrier must be activated,
at gauge level 9.75 mm the light barrier must not be activated
5.5.2 Preparatory measures
Move the feed axis into the zero position (see section 5.2.3 "Checking and setting the zero
offset").

5.5.3 Checking and setting the handle sensors
NOTE
The handle sensors each comprise a reflecting light barrier which can detect the handle of the
WTC or the side of the handle of the WTC XL. An LED indicates the switching status of the sensor.
Fig. 5.5 - 2 Checking and setting the handle sensors
Key
1. Reflecting light barriers of the handle sensors
2. Mounting plates with clamping screws
3. LEDs
Unscrew the clamping screws of the mounting plate.
Move the mounting plate in the direction of the WTC until the reflecting light barrier responds
(the LED will change its status). Fix the plate in place there.
Ensure that the status of the LED remains the same when you move the locked WTC. If ne-
cessary, move the mounting plate a little further in the direction of the WTC.
Firmly tighten the clamping screws.
