Description

Guard locking type

MGB2-L1...

Guard locking by spring force. Release by applying voltage to the guard locking solenoid. (closed-circuit current principle)

Door hinge

On the locking modules, the door stop can be changed from right to left and vice versa at any time with little effort.

New test function

new text update 2026.1

Flexible adaptation through configuration

The evaluation module can be configured with the aid of DIP switches. Depending on the setting, the evaluation module behaves like an MGB2-BP or an MGB2-BR device.

In addition, guard lock monitoring can be switched on or off on devices with guard locking. When guard lock monitoring is switched on, the safe outputs are switched on if the guard is safely locked. When guard lock monitoring is switched off, the safe outputs are switched on if the guard is closed and the bolt tongue is inserted into the MGB2.

Release monitoring can be activated when guard lock monitoring is switched on. This signals whether the auxiliary release or escape release was actuated.

Factor reset permits resetting to the factory setting.
