If a common voltage supply is used, all of the
inductive and capacitive loads (e.g. contactors)
connected to the voltage supply must be
connected to suitable suppressors.
The door signal output OUT must not be used as a
safety output.
It is not permitted to increase the length of the
sensor connecting cable.
The screen of the sensor cable (3 cm max. to be
stripped) must be connected to the earth of the
evaluation unit.
The signal outputs ERR and OUT and the
connection terminals for the read head H1/H2 are
not short-circuit proof.
Should the device not function after the operating
voltage has been connected (e.g. green STATE-
LED does not light); please return the unit
unopened to the manufacturer.
Only copper with a temperature resistance of
75 °C may be used for the wiring.
The screws for the connecting terminal must be
tightened to a tightening torque of 0.6 to 0.8 Nm.
