3–Pump 33-Station Controllers Chapter 7: Troubleshooting 46 of 51
7-2 Alarms
The format for all station alarms is “Station n [alarm text],” for example, “Station 12 receiver
low level.” The format for all pump alarms is “Pump n [alarm text].” Any alarm that does not
start with “Station” or “Pump” is a system alarm.
The following tables list all alarms alphabetically, together with possible causes. A “critical”
alarm is one that causes the affected device to stop.
Note: You can also see a list of alarms and their causes in the
controller’s online help. To display this information, touch the color
key of statuses in the upper right-hand corner of either the “Station
Status” or the “Pump Status” screen, or touch Help at any other
screen. When you are finished reviewing the help, touch Return.
