6.1.2 Fault indications

Fault indications are divided into two sections:
• System alarms and warnings
• Pump alarms and warnings.
System alarms and warnings
These displays show examples of a system alarm
and a system warning.
If a system fault has occurred, the cause will appear
in this display. The value (3) is the fault code.

The fault indication can be reset in this display. If the
fault cause has not disappeared when resetting is
attempted, this will be indicated in the display.
Pump alarms and warnings
These displays show examples of a pump alarm and
a pump warning.
If a pump fault has occurred, the cause will appear in
this display. The value (9) is the fault code.
See section 7.1.2 Pump alarms and warnings.
The fault indication can be reset in this display. If the
fault cause has not disappeared when resetting is
attempted, this will be indicated in the display.
6.1.3 Operating mode
This display is used to set the operating mode and
control source for each individual pump.

generated or the pump is set to "Stop" or "Auto").

pressure sensor).
• R100 (R100 remote control).
