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 (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 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 conguration (using DIP switches) on page 32.

With active guard locking monitoring the following applies:
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 ENISO12100 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 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:
Ì ENISO13849-1
Ì ENISO12100
Ì ENIEC62061
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
Ì ENISO13849-1
Ì ENISO14119
Ì ENIEC60204-1
The safety system MGB2 can 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
Locking 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.
