1) Values at a switching current of 50 mA 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) After the operating voltage is switched on, the safety outputs are switched off during the ready delay. The state of the data outputs is undefined during this time.
4) 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).
5) Applying the limit value from EN ISO 13849-1:2008, section 4.5.2 (MTTF
d
= max. 100 years), BG certifies a PFH
