FH-VHS10 Panel Diagram
1 red LED: Below the setpoint
1 yellow LED: Setpoint reached or exceeded
4 green LEDs: The degree of deviation from the setpoint (1, 2, 3, or 4)
The adjustment method for the FH-VHS10 series single-adjustment thermal flow switch is as follows:
(1) Close the pipeline valve and install the flow switch on the fluid pipe.
(2) Turn on the flow switch power supply and allow it to preheat for about 1 minute.
(3) Adjust the transmission screw on the panel until the red light turns on.
(4) Open the pipeline valve, adjust the flow rate at the setpoint, and wait for about 1 minute to allow the flow to stabilize.
(5) Adjust the transmission screw on the panel to light up 1 to 4 green lights.
(6) Close the pipeline valve; the flow switch will light up red. Open the pipeline valve, and the flow switch will turn green, indicating that the adjustment is correct.
(7) If the LED light is not functioning properly, repeat the steps above.
