1)
In accordance with EN 60947-5-3 corresponds to the risk time. It is the
maximum off delay after the removal of the actuator.
2)
The discrepancy time is the time difference between the switching points
of the two relays.
3)
When the operating voltage is switched on, the relay outputs are switched
off and the door signal contact set to LOW potential during the start-up
delay.
4)
The actuator dwell time inside and outside the response range must be at
least 0.5 s to ensure safe detection of internal errors in the evaluation
device (self-monitoring).
5)
At a current load > 100 mA, a switching frequency of 0.1 Hz should not be
exceeded due to the service life of the relay contacts.
