2. Correct use
The system comprises at least one interlocking module MGB-L0-... and one handle module MGB-H...
The safety system MGB 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.
The interlocking module can be congured with the aid of DIP switches. Depending on the setting, the interlocking module
behaves like an AP or AR device (see chapter 2.1. Main differences between MGB-AP and MGB-AR on page 7). More
detailed information about the possible settings is available in the chapter 11.6. Changing device conguration (using DIP
switches) on page 22.
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
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
Interlocking 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.
ÌCorrect use requires observing the permissible operating parameters (see chapter 13. Technical
data on page 30).
ÌIf a data sheet is included with the product, the information on the data sheet applies.

3. Description of the safety function
Devices from this series feature the following safety functions:
Monitoring of the guard position
(interlocking device according to ENISO14119)
ÌSafety function: the safety outputs are switched off when the guard is open (see chapter 6. Function on page 9).
ÌSafety characteristics: category, Performance Level, PFHD(see chapter 13. Technical data on page 30).
The following applies to devices with emergency stop:
Emergency stop
(emergency stop device according to ENISO13850)
ÌSafety function: emergency stop function
ÌSafety characteristics: B10D value (see chapter 13. Technical data on page 30)
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 fulll personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the guard 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 guard should be checked at suitable intervals as part of the mainte-
nance 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 MGB-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 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. EUCHNER cannot provide any
warranty in relation to the readability of the CD for the storage period required. For this reason you
should archive a printed copy of the operating instructions. You can download the operating instruc-
tions from www.euchner.com.

6. Function
Together with a handle module, the interlocking module makes it possible to monitor the position of moving guards. The
combination also serves as a mechanical door stop at the same time.
DIP
OFF
ON The following switch-on condition applies to the safety outputs FO1A and FO1B (also see chapters 14.2. System
status table MGB-AR on page 32 and 14.3. System status table MGB-AP on page 33):
Conguration System family MGB-AR MGB-AP
Condition
No fault in the device TRUE TRUE
Guard closed TRUE TRUE
Bolt tongue inserted in interlocking module TRUE TRUE
In case of series connection:
Signal available from the upstream switch on the safety inputs FI1A and
FI1B
In case of separate operation:
DC24V present at the safety inputs FI1A and FI1B
TRUE Not relevant
FO1A and FO1B are ON
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.
