Guard locking type
| STA3 | Closed-circuit current principle, guard locking by spring force. Release by applying voltage to the guard locking solenoid. |
Switching element
| 2131 | Slow-action switching contact 2 NC + 1 NO + 1 NC (door monitoring contact) |
Auxiliary releaseIs 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 releaseThis is used for manual release of guard locking from within the danger area without tools. With identification of On/Off position.
