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 230 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
