Sterling 1-Pump 5-Station Controller service manual Station Alarms, Pump Alarms

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.
