Set Up; Indication Of The Switching Status; Function Test - SICK LFV200 Instrucciones De Operación

Set up

If the input of the PLC is high-impedance, you have
to connect a load resistor (R
according to the following illustrations in parallel to
the input of the PLC.
For the plug version valve plug DIN 43650, standard
cable with round wire cross-section can be used.
Cable diameter 4.5 ... 7 mm, protection IP 65.
The M12 x 1 plug connection requires a complete
confectioned cable with plug.

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 Function test

LFV200 has an integrated test switch which can be
activated magnetically. Proceed as follows to test
the instrument:
à
Hold the test magnet (accessory) to the magnet
symbol on the instrument housing
Fig. 18: Function test
The test magnet changes the current switching
condition of the instrument. You can check the
change on the signal lamp. Please note that the
connected instruments are activated during the test.
Caution:
It is absolutely necessary that you remove
the test magnet after the test from the
instrument housing.
