Error memory
In the event of a malfunction, the error memory of
the controller collects and stores the most impor-
tant data such as time of the malfunction, designa-
tion and error code of the malfunction, and meas-
ured values of the sensors. This means that
information on past malfunctions can also be
retrieved at a later point in time.
The controller stores up to 50 malfunctions. If all
50 spaces are occupied, the oldest malfunction is
deleted.
The error memory can be called up as follows:
