1) Without taking into account the load currents on the monitoring outputs.
2) If a switching current > 300 mA in conjunction with a switching voltage > 15 V or an inductive or capacitive load is switched once using the relay outputs, it is no longer possible to reliably switch small currents
(< 15 mA) due to the contact erosion on the gold contacts.
3) Corresponds to the risk time according to EN60947-5-3. 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 EN60947-5-3, 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 followed immediately by further actuation.
4) 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 ashes at a frequency of approx. 15Hz.
5) The dwell time is the time that the actuator must be inside or outside the operating distance.
6) In case of monitoring with feedback loop, the actuators must remain outside the operating distance, e.g. with a door open, until the feedback loop is closed.
