1) Values at a switching current of 4 A without taking into account the cable lengths.
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.
3) The fault detection time is the time for the detection of an internal fault in the device. At least one of the switching elements on each safety output is opened during this process.
4) After the operating voltage is switched on, the semiconductor outputs are switched off during the ready delay.
5) The dwell time of an actuator inside and outside the operating distance must be at least 0.5 s to ensure reliable detection of internal faults in the evaluation unit (self-monitoring).
