Indications in the operating mode

When an actuating object enters the enable zone, the
yellow signal LED illuminates either immediately or with
a time delay depending on the duration of the prior
removal of activation.
The output always switches with normal response
times (see section 9.1 on page 86) without an addi-
tional delay, independent of the behavior of the yellow
LED.
• If the actuating element is in the enable zone (cf.
Tab. 1 on page 61) when the supply voltage is
switched on, the yellow signal LED switches with a
time delay of 5 s.
• If the actuating element was at the safe switch off
distance from the sensor for ≥ 2 s (cf. Tab. 1 on
page 61) and is then brought back into the enable
zone, the yellow signal LED switches with a time
delay of 3 s.
