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 (type4). Devices with unicode evaluation possess
a high coding level, devices with multicode evaluation possess a low coding level.
The locking module can be congured 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 conguration (using DIP switches) on page 32.
ON
With active guard locking monitoring the following applies:
OFF
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 ENISO12100 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 ENISO12100 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 ENISO13849-1
Ì ENISO12100
Ì ENIEC62061
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
Ì ENISO13849-1
Ì ENISO14119
Ì ENIEC60204-1
The safety system MGB2 can be combined only with the intended modules in the MGB2 system family.
On the modication of system components, EUCHNER provides no warranty for function.
Locking modules with the conguration MGB2-BR can be integrated into a BR switch chain.
BR
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.
