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� The outputs definitely 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� With the LED going out the
outputs are maintained in the safe state ("0")� Thus, switching on again in the
enable zone is not possible� Enabling is done by undamping (> 45 mm) of more
than 2 s or by interrupting the voltage (→ 5�2 Protection against simple defeating)�

If the target was away from the
sensor for more than approx� 2 s
(> 45 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�
