INSTALLATION, OPERATION AND TROUBLESHOOTING GUIDE
FLUID COMPONENTS INTL
FCI recommends routing conduit to the enclosure.
Below is a table to determine the wire size needed to route
to the instrument. Connect the customer’s application
(relays, lights, etc,.) to the terminal block switch points as
required. The input power is either 115 VAC, 230 VAC
or 24 VDC and was specified when the instrument was
purchased. Check the part number or paperwork received
with the instrument to determine the type of power to be
applied to the instrument. Connect the power as shown.

Step 5.
Operation
1. Set the flow at the desired rate.
2. Apply power to the instrument and allow 10 minutes for the sensing element to become active and stabilize.
3. Locate the potentiometer (R5) and the red LED on the control circuit. (See the picture below:)
4. Choose procedure A or B below.
A. Detecting No Flow or Decreasing Flow Rate
If the LED is off, turn the potentiometer clockwise until the LED turns on. If the LED is on, turn the potentiometer
counterclockwise until the LED turns off, then turn the potentiometer clockwise until the LED just turns on. With the
LED on, turn the potentiometer slowly counterclockwise until the LED just turns off. Turn the potentiometer one-half
turn past the point at which the LED just turns off. Be aware that the potentiometer may have up to one quarter turn of
hysteresis. If the mark is overshot, the procedure should be repeated. (See the picture and diagram below:)

turn past the point at which the LED just turns off. Be aware that the potentiometer may have up to one quarter turn of
hysteresis. If the mark is overshot, the procedure should be repeated. (See the picture and diagram below:)
B. Detecting Maximum Flow or Increasing Flow Rate
If the LED is on, turn the potentiometer counterclockwise until the LED turns off. If the LED is off, turn the
potentiometer clockwise until the LED turns on, then turn the potentiometer counter clockwise until the LED just turns
off. With the LED off, turn the potentiometer slowly, clockwise until the LED just turns on. Turn the potentiometer
one-half turn past the point at which the LED just turns on. Be aware that the potentiometer may have up to one quarter
turn of hysteresis. If the mark is overshot, the procedure should be repeated. (See the picture and diagram below:)
