e)
Slide the mode switch to the CAL position.
f)
Adjust the calibrate potentiometer (R24) until the voltmeter equals the calculated set point.
g)
For the appropriate alarm, determine whether the status LED is on or off (red for alarm 1 or green for
alarm 2).
1)
If the LED is on, turn the set point adjustment potentiometer (R26 for alarm 1 or R25 for
alarm 2) slowly counterclockwise just until the LED turns off.
2)
If the LED is off, turn the set point adjustment potentiometer ( R26 for alarm 1 or R25 for
alarm 2) clockwise until the LED turns on and then slowly counterclockwise just until the
LED turns off.
8.
Slide the mode switch to the RUN position.
9.
Establish the normal process flow condition. For low-flow alarm setups, the status LED should be off. For high
flow alarm setups, the status LED should be on.
10. Establish the process alarm condition and monitor the voltmeter display.
11. When the output signal passes through the calculated set point value, the status LED should turn on for low-flow
alarms, off for high flow alarms, and the relay contacts should switch.
12. Reestablish the normal process flow condition. Both the LED and the relay contacts should reset.
13. Disconnect the voltmeter from P1 or P2.
