2 Correct use
The system comprises at least one locking module MGB-L1-.../MGB-L2-... and one
handle module MGB-H...
The safety system MGB is an electromagnetic interlocking device with guard locking.
The locking module can be configured with the aid of DIPswitches. Depending on
the setting, the locking module behaves like an AP or AR device. In addition the
guard lock monitoring can be switched on or off. More detailed information about
the possible settings is available in the section 10.5 Changing device configuration
(using DIPswitches), page 21.
With active guard lock monitoring the following applies:
In combination with a movable safety guard and the machine control, this safety
component can prevent opening of the safety guard while a dangerous machine
movement is performed. The position of the guard locking is monitored during
this process.
For the control system, this means that
Ì starting commands which cause hazardous situations must become active
only when the safety guard is in protective position and the guard locking is in
locked position.
The locked position of the guard locking must be released only when the haz-
ardous situation is no longer present.
With inactive guard lock monitoring the following applies:
In combination with a movable separating safety guard, this safety device prevents
dangerous machine movements from occurring while the safety guard is open.
A stop command is triggered if the safety guard is opened during the dangerous
machine function. The position of the guard locking is not taken into account dur-
ing this process.
Before safety components are used, a risk assessment must be performed on the
machine in accordance with
Ì EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.
