3.2 Adjustment and inspection of the switching angle
After the switch has been fitted, the switching function and the opening
angle of the safety guard must be checked. The switching angle of the
NC contacts set in factory is approximately 3°.
Caution: for the TESK...-U version, the following paragraph
"Special instructions for the on-site setting" imperatively must
be observed!
Special instructions for the on-site setting (version TESK...-U)
We recommend a setting including the following steps:
1. Open the safety guard up to the maximum authorised opening angle.
2. Use the adjustment tool to set the NC contacts so that their opening
is ensured at the maximum authorised safety guard opening angle.
Turn clockwise to decrease the switching angle, turn counterclock-
wise to increase the switching angle (Fig. 6); when mounted inside
accordingly reversed.The positive break angle is 7° larger than the
set switching angle.
3. After the switch is set, the compliance of the switch with the safety-
technical requirements of the application must be checked. (See
Section 7.2 Door gap calculation)
4. After the switching angle has been set and checked, the blanking
plug for the adjustment opening located at the rear of the adjustment
tool must be inserted in the adjustment opening (1) and torn down by
making lateral movements (2) with the tool (Fig. 7).

After the desired switching point is set, the opening of the
setting option imperatively must be sealed with a blanking plug.
This measure prevents tampering at the set switching point
within the meaning of EN 14119 paragraph 5.7 and therefore
avoids any loss of the safety function of the device.
The blanking plug is injected to the special adjustment tool with
a predetermined breaking point.
We recommend an additional painting or glueing of the blan-
king plug.
Securing the setting screw by means of the blanking plug is a
mandatory instruction for the user, which must be oberved in
order to maintain the CE-Conformity of the component.
