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