8-2 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.
