2. Correct use
The system consists of at least one locking module MGB2-L1-…/MGB2-L2--… 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.
The locking module can be congured with the aid of DIP switches. Depending on the setting, the locking module behaves
like a BP or BR device (see chapter 2.1. Main differences, MGB2-BP and MGB2-BR on page 8). In addition the guard
locking monitoring can be switched on or off. More detailed information about the possible settings is available in the chapter
13.7. Changing device conguration (using DIP switches) on page 32.
ON
With active guard locking monitoring the following applies:
OFF
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 Starting commands that cause a dangerous machine function must become active only when the guard is
closed and locked.
Ì The guard locking 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 command must be issued. For exceptions, refer to ENISO12100 or relevant C-standards.
With inactive guard locking monitoring the following applies:
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. With inactive guard locking monitoring, guard locking must be used only for process
protection.
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.
Before the device is used, a risk assessment must be performed on the machine, e.g. in accordance with the following
standards:
Ì ENISO13849-1
Ì ENISO12100
Ì ENIEC62061
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
Ì ENISO13849-1
Ì ENISO14119
Ì ENIEC60204-1
The safety system MGB2 can be combined only with the intended modules in the MGB2 system family.
On the modication of system components, EUCHNER provides no warranty for function.
Locking modules with the conguration MGB2-BR can be integrated into a BR switch chain.

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.
Guard locking monitoring can be deactivated using DIP switches (see chapter 13.7. Changing device conguration (using
DIP switches) on page 32).
Important!
For use as guard locking for personnel protection in accordance with ENISO14119, guard locking
monitoring must be active.
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 into 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.

6.2. Guard locking for version MGB2-L1
(Guard locking actuated by spring force and released by power-ON)
Activating guard locking: close guard; no voltage at the solenoid.
Releasing guard locking: apply voltage to the solenoid.
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.
6.3. Guard locking for version MGB2-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 ENISO14119:2013, section 5.7.1)!
Activating guard locking: apply voltage to the solenoid.
Releasing guard locking: disconnect voltage from the solenoid.
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 the locked position and the guard is locked.

8. Manual release
Some situations require the guard locking to be released manually (e.g. malfunctions or an emergency). A function test
should be performed after release.
More information on this topic can be found in the standard ENISO14119:2013, section 5.7.5.1. The device can feature
the following release functions:
8.1. Auxiliary release and auxiliary key release (can be retrotted)
In the event of malfunctions, the guard locking can be released with the auxiliary release irrespective of the state of the
solenoid.
The safety outputs are switched off when the auxiliary release is actuated. Use the safety outputs to generate a stop
command.
The monitoring output OL is switched off; OD indicates the current state of the guard. Open the guard and close it again
after resetting the auxiliary release. The device will then operate normally again.
8.1.1. Actuating auxiliary release
1. Remove seal label or make a hole.
2. Undo locking screw.
3. Using a screwdriver, turn the auxiliary release to in the direction of the arrow.
¨ Guard locking is released.
ON
OFF
Ì When release monitoring is active, the system enters into a latching fault when the auxiliary release is actuated.
See System status table, signal sequence incorrect status (DIA red, Lock ashes 1 time).
Ì The system might not enter into a latching fault if the auxiliary release is actuated very slowly.
Important!
Ì The auxiliary release must be reset at the control system level, e.g. by means of a plausibility
check (status of the safety outputs does not match the guard locking activation signal). See
ENISO14119:2013, sec. 5.7.5.4.
Ì The auxiliary release is not a safety function.
Ì The machine manufacturer must select and use a suitable release (escape release, emergency
unlocking, etc.) for a specic application. A hazard assessment is required for this purpose. It may
be necessary to take specications from a product standard into account.
Ì The correct function must be checked at regular intervals.
Ì Loss of the release function due to mounting errors or damage during mounting. Check the re-
lease function every time after mounting.
Ì Please observe the notes on any enclosed data sheets.
8.1.2. Actuating auxiliary key release
On devices with auxiliary key release (can be retrotted), simply turn the key to release. Function as for auxiliary release.
For mounting, see the auxiliary key release supplement.

Permits opening of a locked guard from outside the danger zone without tools. For mounting, see the mounting supplement.
Important!
Ì It must be possible to operate the emergency unlocking manually from outside the protected area
without tools.
Ì The emergency unlocking must possess a marking indicating that it may be used only in an emer-
gency.
Ì The actuator must not be under tensile stress during manual release.
Ì The unlocking function meets all other requirements from ENISO14119.
Ì The emergency unlocking meets the requirements of Category B according to
ENISO13849-1:2015.
Ì Loss of the release function due to mounting errors or damage during mounting.
Ì Check the release function every time after mounting.
Ì Please observe the notes on any enclosed data sheets.
8.2.1. Actuating emergency unlocking
Ì Turn emergency unlocking clockwise until it clicks into place.
¨ Guard locking is released.
To reset, press the snap-in bolt inward using a small screwdriver or similar tool and turn the emergency unlocking back.
The safety outputs are switched off when the emergency unlocking is actuated. Use the safety outputs to generate
a stop command.
The monitoring output OL is switched off; OD indicates the current state of the guard. Open the guard and close it again
after resetting the emergency unlocking. The device will then operate normally again.
8.3. Lockout mechanism
If the lockout mechanism is pivoted out, the bolt tongue cannot be extended. The lockout mechanism can be secured with
padlocks (see Figure 7). This is intended to prevent people from being locked in unintentionally. The lockout mechanism
does not fulll any safety function.
¨ To pivot out, press the grooved part (possible only with bolt tongue retracted).

8.4. Escape release (optional)
The escape release is used to open a locked guard from the inside without tools.
ON
When release monitoring is active, the system enters into a latching fault when the escape release is actuated.
OFF
See System status table, signal sequence incorrect status (DIA red, Lock ashes 1 time).
The system might not enter into a latching fault if the escape release is actuated very slowly.
Depending on the parameters set in your conguration environment, the system may enter into a latching fault if the escape
release is actuated (see chapter 17. Troubleshooting and assistance on page 51).
Important!
Ì It must be possible to actuate the escape release manually from inside the protected area without
tools.
Ì It must not be possible to reach the escape release from the outside.
Ì The bolt tongue must not be under tensile stress during manual release.
Ì The escape release meets the requirements of Category B according to ENISO13849-1:2015.
Ì The correct function must be checked at regular intervals.
Ì Please observe the notes on any enclosed data sheets.
Ì Fit escape release such that operation, inspection and maintenance are possible.
Ì The actuation axis for the escape release must be inserted min. 9 mm into the handle module. Note the information on
the different prole widths in the chapter 8.4.1. Preparing escape release on page 19.
Ì Align escape release axis at right angles to the handle module. See Figure 9.
