MGB Help for Setup and Service
3.8 LED DIA not illuminated + LED STATE not illuminated or does not
flash
Possible causes:
 Teach-in operation complete.
 DIP switch 5 still set to “ON” (AP/AR configuration process not fully completed yet).
Remedy:
 When the teach-in operation is complete, the operating voltage must then be switched off at the locking
module for at least 3 minutes in order to activate the taught-in code of the handle module in the locking
module. As an alternative, 24V can be applied to the input RST for at least 3 seconds.
 Complete the AP/AR configuration process (set DIP switch 5 to “OFF”), restart the MGB.
3.9 LED DIA not illuminated + LED STATE flashes 3 times
(AR and AP modes)
The device indicates that it is ready to learn a new handle module. Observe the specifications for learning a
handle module in the system manual for this purpose. This state persists for 3 minutes after power up with the
door open.
3.10 LED DIA not illuminated + LED STATE flashes approx. every 3 sec.
(AR and AP modes)
The device displays normal operation with the door open. If this display also occurs with the door close, the
handle module has already been taught in and is currently being blocked on this MGB.
Remedy:
1. Repeat teach-in operation with a new handle module. Observe the instructions for “Teaching in a handle
module” in the system manual for this purpose. Tip: Close the door and activate guard locking to avoid
interruptions during teach-in operation.
3.11 Individual flickering input LED on the evaluation unit
Even when the MGB is switched off, it emits a pulse sequence at output FO1A in order to ensure the functional
capability of the output circuit at all times. Consequently, a faintly flickering LED can be seen on an input of an
evaluation unit even though the evaluation unit does not switch on or signal any fault.
This usually does not result in any problems during operation.
