Description

Guard locking principle

Open-circuit current (power on to lock): On a guard with guard locking based on the open-circuit current principle, the guard is locked until the power supply to the guard locking solenoid is interrupted. Unlocking is by spring force. The term electrical guard locking is also used.

Guard locking for process protection

The safety switch meets the requirements for interlocking devices with guard locking for process protection. It does not possess safe guard lock monitoring.

Switching function

The safety outputs are switched on when guard locking is active.

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.
