Appendix A2
A2.2 Alarms
The pump controller generates an alarm when a serious problem is encountered.
Depending on the reason for the alarm, the whole system or just the booster (if fitted) will shut down - refer to
Section 4.4 and 4.5 for more information about alarms.
If the system has shut down due to an alarm, you must rectify the problem before you try to re-start the pump.
Once the problem that caused the alarm has been resolved, the alarm is cleared by the pump controller.
A2.2.1 LED alarm indicators
Alarms are indicated on the LEDs on the front control panel, the rear panel and on the PDT if fitted.
The alarm LEDs on the front control panel and rear panel illuminate continuously when an alarm is generated.
If a PDT is fitted, the alarm LED flashes to indicate a new alarm. Refer to Appendix A1.3 for more information on how
alarms are indicated and how they can be acknowledged using the PDT.
Once all the alarms are cleared, the alarm LEDs extinguish.
A2.2.2 PDT alarms
If a PDT is fitted, each alarm triggers an alarm message to be displayed. Refer to Appendix A1.3 for more information
on how alarms are handled by the PDT.
Table A16 lists the alarm messages that might be displayed on the PDT with possible causes and actions you should
take.
