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

 

 

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

ninth menu header is for configuring the interval timer.

Always configure the control parameters BEFORE making

 

 

changes in the alarm setup.

To access a header, move the cursor to the desired header and press

 

 

Enter (F4).
