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�

Power
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�
While this mode is active, the output
remains in the safe state ("0")�
1: close zone
2: enable zone
8.2 Determine the enable zone
When the setting aid is active, the enable zone can be determined by moving the
target (or the sensor if the target is fixed)�
