Along with the bus module MBM, the system consists of at least one interlocking module MGB2-I... and one handle module
MGB2-H…
The safety system MGB2-I... is an interlocking device without guard locking (type4). Devices with unicode evaluation possess
a high coding level, devices with multicode evaluation possess a low coding level.
In combination with a movable guard and the machine control, this safety component prevents dangerous machine functions
from occurring while the guard is open. A stop command is triggered if the guard is opened during the dangerous machine
function.
This means:
Ì Starting commands that cause a dangerous machine function must become active only when the guard is closed.
Ì Opening the guard triggers a stop command.
Ì Closing a guard must not cause automatic starting of a dangerous machine function. A separate start command must
be issued. For exceptions, refer to ENISO12100 or relevant C-standards.
For the MGB2-L... the following applies:
Along with the bus module MBM, the system consists of at least one locking module MGB2-L... and one handle module
MGB2-H…
The safety system MGB2-L... is an interlocking device with guard locking (type4). Devices with unicode evaluation possess
a high coding level, devices with multicode evaluation possess a low coding level.
In combination with a movable guard and the machine control, this safety component prevents the guard from being opened
while a dangerous machine function is being performed.
This means:
Ì The unlocking of the guard locking by the control system triggers a stop command.
Ì Starting commands that cause a dangerous machine function must become active only when the guard is closed and
locked.
Ì The guard locking device must not be unlocked until the dangerous machine function has ended.
Ì Closing and locking a guard must not cause automatic starting of a dangerous machine function. A separate start com-
mand must be issued. For exceptions, refer to ENISO12100 or relevant C-standards.

4. Exclusion of liability and warranty
In case of failure to comply with the conditions for correct use stated above, or if the safety instructions are not followed,
or if any servicing is not performed as required, liability will be excluded and the warranty void.
5. General safety precautions
Safety switches fulll personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the guard and, if necessary, other safety functions particularly
Ì after any setup work
Ì each time after replacement of a component relevant to safety
Ì after an extended period without use
Ì after every fault
Ì after any change to the DIP switch settings
Independent of these checks, the safe function of the guard should be checked at suitable intervals as part of the maintenance schedule.
WARNING
Danger to life due to improper installation or due to bypassing (tampering). Safety components perform
a personnel protection function.
Ì Safety components must not be bypassed, turned away, removed or otherwise rendered ineffec-
tive. On this topic pay attention in particular to the measures for reducing the possibility of bypassing according to ENISO14119:2013, section 7.
Ì The switching operation is allowed to be triggered only by the intended handle module MGB2-H…
that is positively fastened to the guard.
Ì Prevent bypassing by means of replacement actuators (only for multicode evaluation). For this
purpose, restrict access to actuators and to keys for releases, for example.
Ì Mounting, electrical connection and setup only by authorized personnel possessing the following
knowledge:
- specialist knowledge in handling safety components
- knowledge about the applicable EMC regulations
- knowledge about the applicable regulations on occupational safety and accident prevention.
Important!
Prior to use, read the operating instructions and keep these in a safe place. Ensure the operating
instructions are always available during mounting, setup and servicing. For this reason you should
archive a printed copy of the operating instructions. You can download the operating instructions from

6. Function
6.1. Interlocking module MGB2-I... (or a correspondingly congured MGB2-L2)
Together with a handle module, the interlocking module makes it possible to interlock movable guards. The combination
also serves as a mechanical door stop at the same time.
The following switch-on conditions apply to safety bit LM.FI_SK (SK):
Ì Guard closed
Ì Bolt tongue inserted in the interlocking module
See also chapter 16.2. System indications during setup, teach-in and normal operation on page 34 and the operating
instructions for bus module MBM.
The interlocking module detects the position of the 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.
6.2. Locking module MGB2-L...
Together with a handle module, the locking module makes it possible to lock movable guards. The combination also serves
as a mechanical door stop at the same time. There are various congurations for the control of the guard locking (see
section 6.3. Control of guard locking MGB2-L1 and MGB2-L2). The following descriptions in 6.2.1 and 6.2.2 describe the
function of the guard locking with the factory setting.
Important!
To operate the device as guard locking for personnel protection according to ENISO14119, the safety
bit LM.FI_UK (ÜK) must be evaluated.
The following switch-on conditions apply to the safety bit LM.FI_UK (ÜK):
Ì Guard closed
Ì Bolt tongue inserted in the locking module
Ì Guard locking in locking position (guard locking monitoring)
See also chapter 16.2. System indications during setup, teach-in and normal operation on page 34 and the operating
instructions for bus module MBM.
The locking module detects the position of the 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.
If the bolt tongue is fully inserted into the locking module, the guard locking can lock the bolt tongue in this position. Depending on the version, this locking is by spring force or solenoid force.
6.2.1. Guard locking for version MGB2-L1
(Guard locking actuated by spring force and released by power-ON)
Guard locking: Close guard; no voltage at the solenoid
(with factory setting: safety bit LM.FO_CL =0.)
Releasing guard locking: Apply voltage to the solenoid (with factory setting: safety bit LM.FO_CL =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 guard locking is closed, the bolt tongue cannot be pulled out of the locking module and the guard is locked.
If voltage is applied to the guard locking solenoid, the guard locking is opened and bolt tongue is released. The guard can
be opened.
6.2.2. Guard locking for version MGB2-L2

Important!
Use as guard locking for personnel protection is possible only in special cases, after strict assessment
of the accident risk (see ENISO14119:2013, section 5.7.1)!
Guard locking: Apply voltage to the solenoid (with factory setting: safety bit LM.FO_CL =0.).
Releasing guard locking: Disconnect voltage from the solenoid (with factory setting: safety bit LM.FO_CL =1.).
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.
If voltage is present at the guard locking solenoid, the guard locking is held in locked position and the guard is locked.
6.3. Control of guard locking MGB2-L1 and MGB2-L2
By changing the parameters in the conguration tool for your control system, you can set which bit combinations are to
be used to control the guard locking. You will nd an overview of the parameters in the operating instructions for the bus
module MBM.
On the use of the guard locking for personnel protection, as standard the guard locking must be controlled from the safe
control area.
On use as guard locking for process protection, the guard locking can also be controlled using a non-safe bit.
The following table shows the possible congurations.
