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. In case of EMC interference in excess of the requirements
in accordance with EN 60947-5-3, the OFF time 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 followed immediately by further actuation.
3) After the operating voltage is switched on, the relay outputs are switched off and the monitoring outputs are set to LOW potential 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 outside the actuating range.
5) In case of monitoring with feedback loop, the actuators must remain outside the actuating range, e.g. with a door open, until the feedback loop is closed.
