6. Function
The device permits the locking of movable guards.
The system consists of the following components as a minimum: coded handle module
(transponder) and locking module.
Whether the locking module learns the complete transponder code (unicode) or not
(multicode) depends on the respective version.
Ì
Devices with unicode evaluation
: The handle module must be assigned to the locking
module by a teach-in operation so that it is detected by the system. This unambiguous
assignment ensures a particularly high level of protection against tampering. The system
thus possesses a high coding level.
Ì
Devices with multicode evaluation
: Unlike systems with unicode evaluation, on multi-
code devices a specific code is not requested but instead it is only checked whether the
handle module is of a type that can be detected by the system (multicode evaluation).
There is no exact comparison of the transponder code with the taught-in code in the
safety switch (unicode evaluation). The system possesses a low coding level.
#The tongue on the handle module is inserted into the locking module when the guard
is closed. When the operating distance is reached, power is supplied to the handle module by the locking module and data
are transferred.
If a permissible code is detected, the safety outputs
are switched on.
The safety outputs
and the monitoring output (OL) are switched off when the guard is released.
In the event of a fault in the locking module, the safety outputs are switched off and the DIA LED illuminates red. The
occurrence of faults is detected at the latest on the next demand to close the safety outputs (e.g. on starting).
6.1.
Guard lock monitoring
All versions feature two safe outputs for monitoring guard locking. The safety outputs (FO1A and FO1B) are switched
off when guard locking is released.
6.2.
Door position monitoring output (OD)
The door position monitoring output is switched on as soon as the door handle is inserted into the switch head (state: guard
closed and not locked). The door position monitoring output also remains switched on when guard locking is active.
6.3.
Diagnostic monitoring output (OI)
The diagnostic monitoring output is switched on in the event of a fault (switch-on condition as for DIA LED).
6.4.
Guard lock monitoring output (OL)
The guard lock monitoring output is switched on when guard locking is active.
6.5.
Version MGBS Extended
Some versions contain additional controls/indicators in the housing cover. Please refer to the enclosed data sheet for
further information.
6.6.
Guard locking for version MGBS-L1
(guard locking actuated by spring force and released by power-ON)
Activating guard locking:
close guard; no voltage at the solenoid.
Releasing guard locking:
apply voltage to the solenoid.
The spring-operated guard locking functions in accordance with the closed-circuit current principle. If the voltage is interrupted
at the solenoid, the guard locking remains active and the guard cannot be opened directly.
