2. Correct use
The system comprises at least one locking module MGB-L2-… and one handle module MGB-H...
The safety system MGB is an interlocking device with guard locking (type 4). Devices with unicode evaluation possess a
high coding level; devices with multicode evaluation feature a low coding level.
In combination with a safety guard and the machine control, this safety component prevents the safety 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 safety guard is closed
and locked.
Ì
The guard locking device must not be unlocked until the dangerous machine function has ended.
Ì
Closing and locking a safety 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.
Locking module MGB-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:
Ì
EN ISO 13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì
EN ISO 12100, Safety of machinery – General principles for design – Risk assessment and risk reduction
Ì
IEC 62061, Safety of machinery. Functional safety of safety-related electrical, electronic and programmable electronic
control systems.
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
Ì
EN ISO 13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì
EN ISO 14119 (supersedes EN 1088), Safety of machinery. Interlocking devices associated with guards. Principles for
design and selection
Ì
EN 60204-1, Safety of machinery – Electrical equipment of machines – Part 1: General requirements
The safety system MGB can only be combined with the intended modules in the MGB system family. Only handle modules
with a version number of V2.0.0 or higher may be used.
On the modification 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.

Important!
Ì
The user is responsible for the correct 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
