Setup and function
The safety locking device is an interlocking device consisting of a mechanically-actu‐
ated position switch and a coded actuator. The actuator has a lower coding level. The
position switch contains a rotating switching cylinder which the actuator grips during
closing. The switching cylinder is locked electromagnetically
When inserting and removing the actuator, switching contacts for door monitoring are
opened and closed. When locking and unlocking the locking device, switching contacts
for locking device monitoring are opened and closed.
If the locking device is locked, the actuator cannot be removed from the actuating head.
The locking device can only be locked when the protective device is closed.

Product characteristics
4.2.1
Locking principle
Operating current locking principle
•
Locking locking device: apply voltage to magnet
•
Unlocking locking device: disconnect voltage from magnet
If voltage is disconnected at the magnet, the locking device is unlocked and the protec‐
tive device can be opened immediately.
DANGER
Hazard due to lack of effectiveness of the protective device
In the event of a voltage drop, the safety locking device unlocks regardless of whether
the dangerous state of the machine has ended.
b
Assess the risk of accident. Use for protecting people requires correct project plan‐
ning.
4.2.2
Door monitoring
The safety locking device features 2 positive opening normally closed contacts for door
monitoring. The output state changes when opening or closing the protective device.
The safety locking device is recommended for process protection.
4.2.3
