• PLe/category 4 for all safety functions
• Handle, bolt and guard locking in one
• Integrated PROFINET-RT switch
• Profisafe integrated

Seamless integration by means of bus connection

In the PROFINET version we now also make the wiring easier for you. You define which element is to be integrated and the related function. The MGB supplies the protocol frame with the necessary PROFINET input and output bytes required. Comprehensive diagnostic information in the form of PROFINET messages makes troubleshooting quick and specific. Due the typical ease with which parameters can be set in PROFINET, even the replacement of the system in case of service is a simple matter and can be undertaken in a few minutes.

Interlocking or guard locking? Functions of the versions MGB-L0, MGB-L1 and MGB-L2 compared

Interlocking (MGB-L0, without guard locking)

Together with a handle module, the interlocking module makes it possible to interlock the control of movable safety guards. The combination also serves as a mechanical door stop at the same time.

The following switch-on condition applies to the safety outputs OA and OB:

• Safety guard closed (but can be opened at any time)
• Bolt tongue inserted in the interlocking module

The interlocking module detects the position of the safety guard and the position of the bolt tongue. The bolt tongue in the handle module is moved into and out of the interlocking module by actuating the door handle.

Guard locking (MGB-L1 and MGB-L2)

Together with a handle module, the locking module makes it possible to lock movable safety guards. The combination also serves as a mechanical door stop at the same time.

The following switch-on condition applies to the safety outputs OA and OB:

• Safety guard closed
• Bolt tongue inserted in the locking module
• Locking arm in locking position (the door cannot be opened)

The locking module detects the position of the safety guard and the position of the bolt tongue. The position of the guard locking is also monitored. The bolt tongue in the handle module is moved into and out of the locking module by actuating the door handle. When the bolt tongue is fully inserted in the locking module, the locking arm locks the bolt tongue in this position. Depending on the version, this locking is by spring force or solenoid force.

• Version MGB-L1: The locking arm is kept in locked position by spring force and is unlocked by solenoid force (closed-circuit current principle, mechanically locked).
• Version MGB-L2: The locking arm is kept in locked position by solenoid force and unlocked by spring force when the solenoid is switched off (open-circuit current principle, electrically locked).
