Product description
2.4.1
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 2.6) without an additional delay,
independent of the behaviour of the yellow LED.
If the actuating element is in the enable area (cf.
Tab. 1) when the voltage supply 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 (cf. Tab. 1) from the sensor for more than
2 s and is then brought back into the enable zone,
the yellow signal LED switches with a time delay of
3 s.
If the actuating element was at the safe switch off
distance (cf. Tab. 1) from the sensor for less than
2 s and is then brought back into the enable zone,
the yellow signal LED switches without a time delay.
If the actuating element is placed at the safe switch
off distance (cf. Tab. 1) from the sensor, the yellow
signal LED extinguishes without a delay.
If the actuating element is placed in the near range
(cf. Tab. 1), the yellow signal LED extinguishes with
a delay of 2 s.
2.4.2
Indications in the adjustment mode
In the adjustment mode (cf. section 4.2)
the yellow signal LED flashes when the actuating
element is outside the enable zone
the yellow signal LED extinguishes when the
actuating element is within the enable zone or in
the safe switch off range
