ALARM SWITCH POINT SET-UP
The set point may be adjusted blindly or with a volt meter to see relative flow and establish a reference point.
In RUN MODE:
0-25mA related to flow.
0-10Vout related to temperature.
Green LED on = power on (run mode).
Red LED indicates fail-safe setting.
Red LED ON = relay de-energized on flow (or wet condition) BELOW the alarm set point.
Red LED OFF = relay de-energized on flow (or dry condition) ABOVE the alarm set point.
CALIBRATION MODE:
To enter calibration mode, press both buttons simultaneously once.
Both LED’s will be off.
Use either output to monitor the alarm set point.
0-10Vout represents the Set Point.
0-25mA represents the Set Point.
Press both buttons simultaneously to exit CALIBRATION MODE and toggle the fail-safe mode.
The Green LED is on and the Red LED is either on or off, indicating fail-safe setting as described above.
To change fail-safe setting, press both buttons simultaneously twice.
