1)  Tested by employers’ liability insurance association up to 75 V.

2)  Values at a switching current of 50 mA without taking into account the cable length.

3)  Maximum OFF time for the safety outputs following removal of the actuator.

4)  After the operating voltage is switched on, the semiconductor outputs are switched off and the monitoring outputs are set LOW during the ready delay.

5)   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).
