7-2 Alarms
The format for all station alarms is “Station n [alarm text],” for example, “Station 9 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.
