5.7 CHANGING ALARM PARAMETERS

1.This section describes how to configure the controller alarms. Alarms 1, 2, and 3 can be assigned to the main amperometric measurement (oxygen, ozone, free chlorine, or total chlorine), temperature, or pH (if pH was enabled). In addition, alarm 1, 2, or 3 can be configured as a feed limit timer or as an interval timer (see steps 10 and 11). Alarm 4 is always a fault alarm.

2.An alarms assigned to the main amperometric measurement, temperature, or pH can be configured as either a simple on/off alarm or as TPC (time proportional control) alarm.

			6. Nine menu headers relate to alarms. Alarms 1, 2 and 3, each have a
	Alarm 1 control
	Alarm 1 control		control header and a setup header. Alarm 4 has only a setup header.
	Alarm 1 setup		The eighth menu header is for configuring the feed limit timer, and the
