2. Correct use
The following applies to MGB2-I…:
The system comprises 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 (type 4). 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:
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
ÌENIEC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IEC60204-1
The safety system MGB2 may be combined only with the intended modules in the MGB2 system family.
On the modication of system components, EUCHNER provides no warranty for function.
BR
Interlocking modules with the conguration MGB2-BR can be integrated into a BR switch chain.
Connection of several devices in a BR switch chain is permitted only using devices intended for series connection
in a BR 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.
ÌCorrect use requires observing the permissible operating parameters (see chapter 15. Technical
data on page 41).
ÌIf a data sheet is included with the product, the information on the data sheet applies.

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 and, if necessary, other safety functions particularly
Ìafter any setup work
Ìafter the replacement of a system component relevant for safety
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 ineffec-
tive. On this topic pay attention in particular to the measures for reducing the possibility of bypass-
ing according to ENISO14119:2013, section 7.
ÌThe switching operation is allowed to be triggered only by the intended handle module MGB2-H…
that is positively fastened to the guard.
ÌPrevent bypassing by means of replacement actuators (only for multicode evaluation). For this
purpose, 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!
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
www.euchner.com.
6. Function
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 condition applies to the safety outputs FO1A and FO1B (also see chapters 14.2. System status table
MGB2-BR on page 36 and 14.3. System status table MGB2-BP on page 38):
ÌGuard closed
ÌBolt tongue inserted into the interlocking module
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.

8.1. Replacing modules
CAUTION
Risk of damage to equipment or malfunction as a result of uncontrolled machine stop.
ÌThe communication within the system is interrupted by the replacement of a module. If a process
is running, this situation can result in an uncontrolled stop and damage to the installation or the
product. Before replacement, make sure the installation is in a suitable operating status.
An interlocking module with the BP conguration can be replaced only in combination with an overall system restart. On
the disconnection of the module connection, the system enters into a fault state. The related module and all downstream
modules remain inactive until the overall system is restarted (fault state).
Interlocking modules with the conguration BR are hot pluggable. It is therefore not necessary to restart the overall system.
8.2. Mounting submodules
CAUTION
Risk of damage to equipment or malfunction as a result of incorrect connection or a conguration
change.
ÌOnly submodules of connection types P, K and N can be used. Check the compatibility before in-
stallation. For information on the related connection type of a submodule, refer to the data sheet
for the related submodule. This is included with each submodule.
ÌPay attention to the alignment of the submodule. See marking (a) in Fig. 10: Mounting submodule.
Submodules can also be installed rotated by 180°. The marking (a) always indicates the rst posi-
tion to be equipped. This is the emergency stop S1 position in the example below.
ÌMake sure the pins on the submodule slide straight into the guide. Tighten the cover screws to 0.5
Nm.
ÌIf you use a submodule, pay attention to the correct alignment of the modules in relation to the
labeling elds on the connection module. Incorrect assignments can cause serious malfunctions in
your installation.
ÌMake sure no foreign bodies, e.g. swarf or wires, enter the open submodule slots. These can
cause short circuits or contact problems.
ÌAvoid touching the contacts on the underside of the submodule. Risk of ESD damage and contact
problems due to soiling.
ÌUnused submodule slots must be tted with a cover (e.g. order number 126372).

8.3. Replacing submodules
CAUTION
ÌThe communication between submodule and interlocking module is interrupted by the replacement
of a submodule. The submodule ceases to function. The function of the interlocking module, e.g.
the safety outputs FO1A / FO1B, is not affected. If a process is running, the removal/replacement
of a submodule can result in an uncontrolled stop and damage to the installation or the product.
Before replacement, make sure the installation is in a suitable operating status.
NOTICE
Pay attention to the information on the replacement of a submodule in the operating instructions for
the related module. Correct function must be tested after replacement before the system enters
normal operation again.
The replacement of submodules MSM while in operation is also possible (pay attention to safety note above). As soon as
the system detects a compatible submodule, the submodule is ready for operation.
If an incompatible submodule is installed, the Slot1 LED illuminates red.
8.3.1. Replacing submodule with a submodule with a different function (changing conguration)
The use of a different submodule will change the function and as a result the terminal assignment (see data sheet for the
submodule). Take into account the changes in your wiring and control system.

8.4. Changing direction of connection
CAUTION
Risk of damage to equipment or malfunction as a result of uncontrolled machine stop.
ÌThe direction of connection can be changed by removing the covers and mounting rotated by
180°.
ÌThe communication within the system is interrupted if the internal wiring is changed. If a process is
running, this situation can result in an uncontrolled stop and damage to the installation or the prod-
uct. Before replacement, make sure the installation is in a suitable operating status.

9. Changing the door hinge position
9.1. Changing the interlocking module to a different door hinge position
To change the interlocking module for doors with a different door hinge position, the module only needs to be rotated by
180°. Submodules installed in the module can also be rotated by 180° (see section 8.1. Replacing modules on page 17).
9.2. Changing actuating direction of the handle module
(here: from right to left)
Important!
It is possible to make this change only when the bolt tongue is not extended and an escape release
is not yet mounted.
In the delivery state, the handle module is set either for doors hinged on the right or for doors hinged on the left.
Based on the example of a handle module for doors hinged on the right this means:
ÌThe guard opens by pressing down the door handle.
ÌThe system is mounted the other way up for doors hinged on the left. In other words, the guard opens by pressing up
the door handle (see Fig. 12). For this reason the actuating direction of the door handle must be changed (see Fig. 12
to Fig. 21).
(Similarly on handle modules for doors hinged on the left)
