Ismertetés
Guard locking principle
Power to unlock: On a guard with guard locking based on the closed-circuit current principle, the guard is locked by spring force until the guard locking solenoid is supplied with power. Unlocking is by solenoid force. The term mechanical guard locking is also used.
Multicode evaluation
The system checks whether the actuator type is one that can be recognized by the system (multicode evaluation). The system has a low coding level. Every suitable actuator is recognized by the switch.
Safety characteristics
Thanks to two redundant safety outputs (semiconductor outputs) with internal monitoring, the device is suitable for:
- Category 4 /PL e according to EN 13849-1
- SIL 3 according to EN IEC 62061 Table 4
The OSSD outputs used check their function for short circuits and short circuits with test pulses.
