dard cable with round wire cross-section can be
used. Cable diameter 4.5 ... 7 mm, protection
IP65.
The M12 x 1 plug connection requires a ready-
made cable with plug.

5 Setup
5.1 Indication of the switching
status
The switching status of the electronics can be
checked via the signal lamp integrated in the
upper part of the housing.
5.2 Simulation
The LFV 200 has an integrated function for

simulation of the output signal which can be ac-
tivated magnetically. Please proceed as follows:
→
Hold the test magnet (accessory) against
the circle symbol with the label "TEST" on
the instrument housing
Abb. 19: Simulation of the output signal
The test magnet changes the current switching
condition of the instrument. You can check the
change on the signal lamp. Please note that
all connected device are activated during the
simulation.
Caution:
It is absolutely necessary that you remo-
ve the test magnet from the instrument
housing after the simulation.
