8.1 General
If there is a malfunction or alarm on the device, a corre-
sponding error message will be displayed. The corre-
sponding LED on the command panel will be illuminated
and the alarm relay switched where applicable (collec-
tive fault signal).
Errors are divided into three categories.
1.
Alarms: The device will be stopped (at least individ-
ual components).
2. Warnings: Selected device functions will no longer
be executed.
3. Messages: A message is output on the display (for
example, if a limit is exceeded) but the device re-
mains operational.

Press the "Alarm" button on the command panel to
view all active error messages.
The location of the error and the component affected
will be shown on the display.

In the event of multiple errors, use the "Up" and
"Down" buttons to scroll through the list.

Press the "Alarm" button again to confirm the currently
selected error.
Once the cause of the error has been rectified, the er-
ror message will be deleted from the list.
The following additional information about the error mes-
sages will be output at the end of the aforementioned list
of error messages:
1. Sequence of error messages. "E01" is the oldest er-
ror, "E02" the one after that, and so on.
2. Date and time when the error occurred.
3. The alarm code, e.g. "ALF01".
4. A brief description of the cause of the error.
5. Inlet and outlet temperature and high and low pres-
sure in the cooling circuit.
