Adjustment Instructions MTC 2 5 Feed axes

12/2007 Edition 5.5 Light barriers

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.

5.5.4 Checking and setting the WTC safety queries

NOTE

The WTC safety queries each comprise a light barrier which is interrupted by the front edge of the

WTC or the WTC XL. Two LEDs indicate the switching status of the sensor.

NOTE

Make the settings for the feed axis of tower 1 first and then the feed axis of tower 2.

The light barrier holder in the middle accepts the light barriers for both axes but cannot be set

separately. When making settings, both the holder for the sender and the holder for the receiver

of the light barrier pairs must be moved.
