7 Electrical connection

Wiring diagram → 10 Technical data
► Disconnect power. Also disconnect any independently supplied relay load
circuits.
► Supply voltage: connect L+ to pin 1 and L- to pin 3 of the connector.
The nominal voltage is 24 V DC. This voltage may vary between 19.2 V and
30 V incl. 5 % residual ripple to EN 61131-2.
In case of one fault the supply voltage must not exceed 60 V DC for more
than 0.2 s up to a max. value of 120 V DC. (This requires the safe separa-
tion between power supply and transformer.)

8 Set-up

8.1 Setting aid

For easy and reliable installation the sensor features an optical setting aid to
visualise the enable zone.

The setting aid is activated by
placing a metal object in front of the
fail-safe sensor (close range).
After approx. 5 s the yellow LED
starts to flash: the setting aid is
active.
