5.1. Calibration Mode
1. Switch 1 must be in OFF position.
2. Induce in the pipe the flow rate corresponding to your Alarm
condition (it should be as stable as possible).
3. Turn the potentiometer (
clockwise
) until the led becomes
green (not necessary if the led is already green).
4. Turn the potentiometer in the opposite direction (
anti clockwise
) until the led turns
red. You must stop turning the potentiometer as soon as the led turns red.
5. Now the Alarm calibration is complete.
5.2. Operative Mode
Switch 1 must be in ON position.
Switch 2 can be used to select the most
suitable switch delay:
OFF position to select the 3 second
switch delay
ON position to select the 10 seconds switch delay
The electronics recognise switch 2 modification after ten seconds.
