1) Tested by BG up to 75 V.
2) Values at a switching current of 50 mA without taking into account the cable lengths.
3) 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.
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 operating distance must be at least 0.5 s to ensure reliable detection of internal faults in the evaluation unit (self-monitoring).
6) Applying the limit value from EN ISO 13849-1:2008, section 4.5.2 (MTTF

5) Category 4 according to EN 13849-1 for monitoring short circuits of safety outputs. A short circuit between LA and LB must be detected by external pulsing or must be excluded by laying
the cable with protection.
