Service

Updating the controller software
The controller is programmed in the factory with the latest controller
software at the time of production. Therefore, the software does not
usually have to be updated.
However, if you would like to use newer controller software or if an
update is recommended for technical reasons, you can transfer new
controller software to the controller via the RS3 interface.
Further information in this regard can be obtained from your dealer.

Fault finding

The controller is a quality product, conceived for years of continuous
trouble-free operation. If a problem occurs, the cause of the problem
often lies not in the controller but in the peripheral components. The fol-
lowing description of some causes of problems should help the installer
and operator to isolate the problem so that the system can be repaired
as quickly as possible and to avoid unnecessary costs. Of course, not all
possible causes of problems can be listed here. However, here you will
find the most common causes of problems that cover the majority of
possible faults. Only return the controller when you are absolutely sure
that none of the problems listed below is responsible for the fault.
