2. Correct use
The system may be operated only in the combination as purchased.
The safety system MGB2 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.
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 system MGB2-L2B-PN… is operated as an IO device in the PROFINET (PROFIsafe).
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 MGB2 may be combined only with the intended modules in the MGB2 system family. Only the enabling
switch designated for this purpose (ZSB122338) may be connected.
On the modication of system components, Euchner provides no warranty for function.
The customer is responsible for the safe overall function, especially for the safe integration into the PROFIsafe environment.
Comprehensive information about proper conguration, mounting and setup for PROFINET installations can be found at
http://www.probus.com/.
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 16. Technical
data on page 58).
ÌIf a data sheet is included with the product, the information on the data sheet applies.

3.4. Determining safety characteristics of the overall system
The corresponding reliability values must be determined for each safety function in the overall system. Proceed as follows:
1. Refer to the data sheets or operating instructions for the system components containing the function for information on
the reliability values for the related safety function.
2. Refer to the reliability value of the bus module MBM for the evaluation and forwarding of safety data.
3. Add together the values to a resulting reliability value PFHD, Sys

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 a system component relevant for safety
Ìafter an extended period without use
Ìafter every fault
Ìafter any change to the DIP switch settings
Ìafter every factory reset
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 perform
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 MGB2-H…
that is positively fastened to the guard.
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
6.1. 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 congurations for the control of the guard locking (see
section 6.2. Control of guard locking). The following descriptions in chapter 6.1.1 describe the function of the guard locking
with the factory setting.
Important!
To operate the device as guard locking for personnel protection according to ENISO14119, the safety
bit SI1_1 (ÜK) must be evaluated.
The following switch-on conditions apply to the safety bit SI1_1 (ÜK):
ÌGuard closed
ÌBolt tongue inserted into the locking module
ÌGuard locking in locking position (guard lock monitoring)
See also chapter 15. Diagnostics, troubleshooting and aids on page 45.
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. This
is performed by solenoid force.
6.1.1. Guard locking for version MGB2-L2
(guard locking actuated by power-ON and released by spring force)
Important!
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)!
ÌGuard locking will be released during power-up or if communication is lost.
Guard locking: Apply voltage to the solenoid (with factory setting: safety bit SO0_0=1 and/or O0_0=1 in slot 3).
Releasing guard locking: Disconnect voltage from the solenoid (with factory setting: safety bit SO0_0=0 and O0_0=0
in slot 3).
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 closed position and the guard is locked.
Guard locking is controlled via safety bit SO0_0 and non-safe bit O0_0. Refer to the table in chapter 6.2. Control of guard
lockingfor the exact conguration.

6.2. Control of guard locking
By changing the parameters in the conguration 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 exclusively using a non-safe bit.
The following table shows the possible congurations.
