Description

Solenoid operating voltage

  • AC/DC 24 V +10%, -15%

Pushbuttons

  • Green pushbutton, illuminated
  • Pushbutton blue, illuminated

Guard locking type

STP3

Closed-circuit current principle, guard locking by spring force. Release by applying voltage to the guard locking solenoid.

Switching element

4141

Slow-action switching contact 2 NC + 2 NC (door monitoring contact)

Auxiliary release

This is used for releasing the guard locking with the aid of a tool. To protect against tampering, the auxiliary release is sealed with sealing lacquer.

Escape release

This is used for manual release of guard locking from the danger zone without tools.
