Special instructions for the on-site setting (version TESF.../U)
We recommend a setting including the following steps:
1. Open the safety guard up to the maximum authorised opening angle.
2. Open the enclosure cover of the hinge switch.
3. Wire both NC contacts parallel, connect terminal 11 with 31 and
terminal 12 with 32 (Fig. 5).
4. Connect the continuity tester to the terminals 11/12 of the NC con-
tacts or use the test handles at the terminals (Fig. 5).
5. 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.
6. After the switch is set, the compliance of the switch with the safe-
ty-technical requirements of the application must be checked.
7. 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 set-
ting option imperatively must be sealed with a blanking plug.
This measure prevents tampering at the set switching point
within the meaning of ISO 14119 paragraph 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
blanking 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.
