1) Without taking into account the load currents on the monitoring outputs.
2) Corresponds to the risk time according to EN 60947-5-3. This is the maximum OFF time for the safety outputs following removal of the actuator.
3) After the operating voltage is switched on, the relay outputs are switched off and the door monitoring output is set to LOW potential during the ready delay.
4) The dwell time of an actuator inside and outside the actuating range must be at least 0.5 s to ensure reliable detection of internal faults in the evaluation unit (self-monitoring).
5) If the current load is > 100 mA, a switching frequency of 0.1 Hz should not be exceeded as this will affect the mechanical life of the relay contacts.
6) Not short circuit-proof.
