2. Correct use
The system comprises at least one locking module MGB-L1-…/MGB-L2--… and one handle module MGB-H…
The safety system MGB is an interlocking device with guard locking (type4). Devices with unicode evaluation possess a
high coding level, devices with multicode evaluation possess a low coding level.
The locking module can be congured with the aid of DIP switches. Depending on the setting, the locking module behaves
like an AP or AR device (see chapter 2.1. Main differences between MGB-AP and MGB-AR on page 7). In addition, the
guard lock monitoring can be switched on or off. More detailed information about the possible settings is available in chapter
12.6. Changing device conguration (using DIP switches) on page 26.
DIP
OFF
ON The following applies to active guard lock monitoring:
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:
ÌStarting commands that cause a dangerous machine function must become active only when the guard is closed
and locked.
ÌThe guard locking must not be released until the dangerous machine function has ended.
ÌClosing 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 ENISO12100 or relevant C-standards.
The following applies to inactive guard lock monitoring:
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 lock monitoring, guard locking must be used only for process
protection.
This means:
ÌStarting commands that cause a dangerous machine function must become active only when the guard is closed.
ÌOpening the guard triggers a stop command.
ÌClosing a guard must not cause automatic starting of a dangerous machine function. A separate start command
must be issued. For exceptions, refer to ENISO12100 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:
ÌENISO13849-1
ÌENISO12100
ÌIEC62061
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
ÌENISO13849-1
ÌENISO14119
ÌEN60204-1
The safety system MGB can be combined only with the intended modules in the MGB system family.
On the modication of system components, EUCHNER provides no warranty for function.
AR
Locking modules with the conguration MGB-AR can be integrated into an AR switch chain.
Connection of several devices in an AR switch chain is permitted only using devices intended for series connection
in an AR switch chain. Check the operating instructions for the related device.
Important!
ÌThe user is responsible for the proper integration of the device into a safe overall system. For this
purpose, the overall system must be validated, e.g. in accordance with ENISO13849-2.

4. Exclusion of liability and warranty
In case of failure to comply with the conditions for correct use stated above, or if the safety regulations 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 fulll personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the safeguard particularly
Ìafter any setup work
Ìafter the replacement of an MGB component
Ìafter an extended period without use
Ìafter every fault
Ìafter any change to the DIP switch settings
Independent of these checks, the safe function of the safeguard 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 fulll
a personnel protection function.
ÌSafety components must not be bypassed, turned away, removed or otherwise rendered ineffective.
On this topic pay attention in particular to the measures for reducing the possibility of bypassing
according to ENISO14119:2013, section 7.
ÌThe switching operation is allowed to be triggered only by the intended handle module MGB-H… that
is positively fastened to the guard.
ÌPrevent bypassing by means of replacement actuators (only for multicode evaluation). For this pur-
pose, restrict access to actuators and to keys for releases, for example.
ÌMounting, 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 operational safety and accident prevention.
Important!

TRUE TRUE irrelevant irrelevant
FO1A and FO1B are ON
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 lock monitoring can be deactivated using DIP switches (see chapter 12.6. Changing device conguration (using DIP
switches) on page 26).
Important!
For use as guard locking for personnel protection in accordance with ENISO14119, guard lock
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 version, this locking is by spring force or solenoid force.
6.1. 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.
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 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.

6.2. Guard locking for version MGB-L2
(guard locking actuated by power-ON and released by spring force)
Important!
ÌGuard locking devices according to the open-circuit current principle are not intended for protecting
personnel.
ÌUse 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.
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.
When voltage is applied to the guard locking solenoid, the locking arm 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 ENISO14119:2013, section 5.7.5.1. The device can feature
the following release functions:
8.1. Auxiliary release
In the event of servicing, the guard locking can be released with the auxiliary release irrespective of the state of the solenoid
(see Fig. 5).
DIP
OFF
ON ÌWhen 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).
ÌThe system might not enter into a latching fault if the auxiliary release is actuated very slowly.
Important!
ÌThe auxiliary release must be reset at the control system level, e.g. by means of a plausibility check (sta-
tus of the safety outputs does not match the guard locking control signal). See ENISO14119:2013,
sec. 5.7.5.4.
ÌThe auxiliary release is not a safety function.
ÌThe machine manufacturer must select and use a suitable release (escape release, emergency
release, etc.) for a specic application. A hazard assessment is required for this purpose. It may be
necessary to take specications from a product standard into account.
ÌThe correct function must be checked at regular intervals.
ÌLoss of the release function due to mounting errors or damage during mounting. Check the release
function every time after mounting.
ÌObserve the notes on any associated data sheets.
The locking screw must be screwed back in and sealed (with sealing lacquer, for example) after mounting and after every
use of the auxiliary release. Tightening torque 0.5 Nm.
