Information
If not operated, the plunger of the locking plungers GN 816.1 is retracted. To move out, move against the spring force and hold in the end position by turning by 90°.
The shape of the cam curve secures the plunger against accidental operation.
For the execution with operation with key (Type B / BK) a key is required to move the plunger. In this execution, a cover sleeve provides additional security and safety from unauthorized removal of the locking plunger. The cover sleeve also provides additional protection against malfunction caused by dirt.
