Set Points: If the preset factory calibration is not adequate for
your application, follow the calibration steps listed below. Note: the
switch's internal LED will be on when the switch detects no-flow and
will off when the switch detects flow.
1. Install the fitting and flow switch as described in the Installation
section of this manual. Turn the flow switch and controller power
on and adjust the flow rate to the application setting. If the medi-
um to be sensed is likely to be subject to high temperature varia-
tions, the flow switch should be set at the highest normal temper-
ature likely to be encountered.
2. Locate the potentiometer knob at the top
of the flow switch. The red LED is visible
through the potentiometer. (If the LED is
on, slowly adjust the potentiometer coun-
terclockwise, with a small flat head
screwdriver until the LED turns off.) The
adjustment is a single turn 270° poten-
tiometer. The initial response time of the
flow switch after adjustment is 1 to 10
seconds. Adjust the potentiometer in slow
increments and wait for the response.
If the LED is off, slowly adjust the poten-
tiometer clockwise until the light turns on.
Then turn the potentiometer counterclockwise to bring the LED
off at a reliable setting. Remember, adjust the potentiometer in
slow increments and wait for the response.
3. Verify that the new calibration is correct by lowering the system
flow rate below the set point and check to see that the red LED
turns on. Then increase the flow rate above the set point and ver-
ify that the red LED turns off accordingly.
