play The storage system performs a system self-diagnosis that automatically detects
many faults that may occur. These are indicated on the display or via LEDs. This
means you are promptly made aware of malfunctions in the storage system, or of
any installation or operating faults.
If the system self-diagnosis has detected a specific fault, the associated status
code will be shown on the display.

Error message –
Data converter If the data converter detects an error, the “State” LED lights up steady red to
signal that an error has occurred. At the same time, the associated error mes-
sages are displayed via the “Error No” LEDs in accordance with table below.
There are two different error categories:
Serious errors (1 - 5): In this case, the data converter has to be switched off and
then back on again. If the error recurs, the data converter must be replaced and
sent away for repair.
Warnings (6 - 15): These warnings are displayed for information only. They appear
for 1 minute and are then reset automatically. If these warnings occur quite fre-
quently, Customer Services should be notified accordingly.
These displays are not applicable in Configuration mode and are intended for in-
ternal purposes only.
