Numerical Alarm Set Point Adjustment
The control circuit has two mutually exclusive alarms; they are identified as Alarm No. 1 and Alarm No. 2. Each has
an alarm set point adjustment potentiometer and LED indicator. Both alarms can be setup for one of three
applications; flow, level/interface, or temperature. The following application specific adjustment procedures are
generic and can be used for setting either or both alarms. Use Figure 3-2 to help locate the important setup
components (potentiometers, LEDs, etc.).
