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.
