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 6). More
detailed information about the possible settings is available in the chapter 11.6. Changing device conguration (using DIP
switches) on page 21.
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:
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 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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!
Ì The 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.
Ì Correct use requires observing the permissible operating parameters (see chapter 13. Technical
data on page 29).
Ì If a data sheet is included with the product, the information on the data sheet applies.
