Operating Mode; Delayed Switching Of The Led - Reer PI SQ F-NF Manual De Instrucciones

9.2 Operating mode

The length of the preceding undamping determines whether the yellow LED
comes on with a delay (→ 9.2.1) or without delay (→ 9.2.2) when a target moves
into the enable zone. In any case, the outputs switch on without delay.
In case of undamping the outputs switch off and the yellow LED goes out without
delay.
In case of damping in the close range the outputs switch off immediately whereas
the yellow LED goes out with a delay of approx. 2 s. When the LED goes out the
outputs are maintained in the safe state ("0"). Thus, switching on again in the en-
able zone is not possible. Enabling is done by undamping (> 30 mm) of more than
2 s or by interrupting the voltage (→ 5.2 Protection against simple defeating).

Power
If the target was away from the
sensor for more than approx. 2 s
(> 30 mm), the yellow LED goes on
with a delay of approx. 3 s in case of
damping in the enable zone.
This is also the case if the target is in
the enable zone when the voltage is
switched on.
