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 switch-off delay for the safety outputs following removal of the actuator. In case of EMC interference in excess of
the requirements in accordance with EN 60947-5-3, the switch-off delay can increase to max. 430 ms. After a brief actuation < 0.4 s, the switch-on delay can increase to max. 3 s if this is fol-
lowed immediately by further actuation.
3) After the operating voltage is switched on, the relay outputs are switched off and the monitoring outputs are set HIGH during the ready delay. For the visual indication of the delay, the green
STATE LED flashes at a frequency of approx. 15 Hz.
4) The dwell time is the time that the actuator must be inside or outside the operating distance.
5) In case of monitoring with feedback loop, the actuators must remain outside the operating distance, e.g. with a door open, until the feedback circuit is closed.
