2. Correct use
The modular devices described here can only be operated with a suitable bus module MBM-...-MLI-....
For the MGB2-I... the following applies:
Along with the bus module MBM, the system consists of at least one interlocking module MGB2-I... and one handle module
MGB2-H…
The safety system MGB2-I... 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.
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.
For the MGB2-L... the following applies:
Along with the bus module MBM, the system consists of at least one locking module MGB2-L... 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.
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
The unlocking of the guard locking by the control system triggers a stop command.
Ì
Starting commands that cause a dangerous machine function must become active only when the 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 guard must not cause automatic starting of a dangerous machine function. A separate start com-
mand must be issued. For exceptions, refer to EN ISO 12100 or relevant C-standards.
For MGB2-I.. /MGB2-L..
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
EN IEC 62061, Safety of machinery – Functional safety of safety-related electrical, electronic and programmable elec-
tronic control systems.
