9 Circuit symbol and interlocking
Mechanische Funktion:
I Actuator inserted
and locked
II Actuator inserted
and unlocked
III Actuator withdrawn
Switching function 1: Safety device
Schaltfunktion 2: Latching device
(magnet)
Locking principle: Spring force (closed-circuit current)
The safety guard is locked automatically when the actuator is
inserted to its end position. The power supply to the electromagnet
releases the lock and the safety guard can then be opened.

11 Maintenance / Servicing

The switching device is maintenance-free.
For long and trouble-free operation, regular checks should be carried
out to ensure that:
• all components are seated securely
• the switching function operates reliably
• all sealing elements are in proper condition
• there are no signs of wear and tear
If any defects are found, the complete switching device must be
replaced.

I
Locking principle: Magnetic force (working current)
The lock (latching device) is deactivated when the electromagnet is
de-energised, in the event of fault in actuation or power failure. The
safety guard can then be opened.
1. Undo lock screw
2. Turn release element by 90° with hexagon socket
The actuator can now be withdrawn
Turn release element back to original position
3. Screw in lock screw and seal with screw locking compound (M = 0.5 Nm).
The auxiliary release should only be operated by means of the WAF 3
hexagon socket if the latching device fails.
The access point must be sealed after installation (e.g. with locking
compound).
