Description

BiState (bistable guard locking)

The device has a function that prevents

  • people from accidentally becoming trapped in the event of a power failure or when the machine is switched off and the safety door is open


  • the activated guard locking is deactivated in the event of a power failure.

Approach direction

Horizontal and vertical

Can be adjusted in 90° steps

Increased overtravel with horizontal approach direction

If increased play is required when the door is closed, an actuator with overtravel is available. This actuator allows the door to move slightly in the actuating direction when closed. This is important, for example, if safety doors have a rubber buffer as an end stop. An actuator with overtravel can reduce the permanent pressure of the compressed rubber buffer. This reduces the load on both the switch head and the door mechanism.

Switching element

2131

Slow-action switching contact

Contacts for guard locking: 2 positively driven, positively driven contacts 1 NO contact

Contacts for door monitoring: 1 NC contact

Auxiliary release

The auxiliary release on the front 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).

Required accessories

Actuator is not included in the scope of delivery.
