6.3. 

Guard locking for version MGB-L1

(guard locking actuated by spring force and released by power-ON)

Activating guard locking:

 close guard, no voltage at the solenoid (safety bit 

SO 1

 = 0).

Releasing guard locking:

 apply voltage to the solenoid (safety bit 

SO 1

 = 1).

The spring-operated guard locking functions in accordance with the closed-circuit current principle. If the voltage is interrupted 

at the solenoid, the guard locking remains active and the guard cannot be opened directly.

Important!

If the guard is open when the power supply is interrupted and is then closed, guard locking is activated. 

This can lead to persons being locked in unintentionally.

As long as the locking arm is closed, the bolt tongue cannot be pulled out of the locking module and the guard is locked.
When voltage is applied to the guard locking solenoid, the locking arm is opened and bolt tongue is released. The guard 

can be opened.

6.4. 

Guard locking for version MGB-L2

(guard locking actuated by power-ON and released by spring force)

Important!

Use as guard locking for personnel protection is possible only in special cases, after strict assessment 

of the accident risk (see EN ISO 14119:2013, section 5.7.1)!

Activating guard locking:

 apply voltage to the solenoid (safety bit 

SO 1

 = 1).

Releasing guard locking:

 disconnect voltage from the solenoid (safety bit 

SO 1

 = 0).

The magnetically actuated guard locking operates in accordance with the open-circuit current principle. If the voltage is 

interrupted at the solenoid, the guard locking is released and the guard can be opened directly! 
The guard can be opened as long as no voltage is applied to the guard locking solenoid.
When voltage is applied to the guard locking solenoid, the locking arm is held in the locked position and the guard is locked.
