6. Function
The device monitors the position of movable guards.
The system consists of the following components: coded handle module (transponder)
and interlocking module.
Whether the device 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
interlocking 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 tam-
pering. The system thus possesses a high coding level.
Ì
Devices with multicode evaluation
: Unlike systems with unique code detection,
on multicode 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 (mul-
ticode detection). There is no exact comparison of the transponder code with the
taught-in code in the interlocking module (unique code detection). The system pos-
sesses a low coding level.
The tongue on the handle module is inserted in the interlocking module as the guard is closed. When the switch-on distance
is reached, power is supplied to the transponder in the handle module by the interlocking module and data are transferred.
If a permissible code is detected, the safety outputs are switched on.
The safety outputs are switched off when the guard is opened.
In the event of a fault in the interlocking 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.
Door monitoring output (OD)
The door monitoring output is switched on as soon as the bolt tongue of the handle module is inserted in the interlocking
module (state: guard closed).
6.2.
Diagnostic output (OI)
The diagnostic output is switched on in the event of a fault (switch-on condition as for DIA LED).
6.3.
Version MGBS Extended
Some versions contain additional controls/indicators in the housing cover. Please refer to the enclosed data sheet for
further information.

The detailed switching states for your interlocking module can be found in the system status table. All safety outputs, mon-
itoring outputs and display LEDs are described there.
