Fixing the sensor
When all the settings are done, secure the sensor by tightening
the red screws on the mounting brackets.
The operating voltage (terminals 1+2) and the relay output
(terminals 3, 4 and 5) need only be connected once to any sensor.
Note:
The NC or NO (Terminal 10 and 12) contact can be selected and led
to the door control.
It is not necessary to provide a separate power supply for the
external sensor (verify transformer capacity to support devices).
Several sensors can be connected to one another using the flat-ribbon connections.

Power for an external sensor
The voltage corresponds to the supply voltage
at terminal 1 and 2.
An external sensor is connected via the plug-in screw terminal 7–12.

Affix the end caps after attaching the cover. Affix the end caps
with
alignment pins on the profile side. Optional: Affix the end caps with screws
for reinforced fixation. Therefore pierce through the drill-hole.
