- Guard locking pin right
- Closed-circuit current principle
Ismertetés
Guard locking principle
closed-circuit current (power to unlock): In a safety guard with guard locking according to the closed-circuit current principle, the guard is locked by spring force until the guard locking solenoid is supplied with current. The guard is unlocked by means of magnetic force. This is also referred to as mechanical guard locking.
Switching element
528 | Slow-action switching contact |
Contacts for guard locking: 1 positively driven, positively driven contact |
Auxiliary release with triangular wedge
The auxiliary release on the switch head allows access to the machine in the event of a malfunction, e.g. a power failure. It is unlocked using a tool or a key. The auxiliary release must be secured against misuse (sealing, laking).
Contact separation
When actuated, the contacts 
are opened. The guard locking is not completely released. To prevent tampering, the contact separation must be sealed (e.g. with sealing lacquer).
Without prevention of inadvertent locking position (faulty closure protection)
The TK safety switch does not have a prevention of inadvertent locking position (faulty closure protection). This must be implemented separately.
