Signal Wiring

F6600 / F6650 and F6700 / F6750 Series Displays

WIRING OVERVIEW

Electrical connections are made via screw-clamp terminals located on the back of the display. All conductors should conform to the meter’s
voltage and current ratings. All cabling should conform to appropriate standards of good installation, local codes and regulations. It is
recommended that power supplied to the meter (DC or AC) be protected by a fuse or circuit breaker.

When wiring the display, compare the numbers embossed on the back of the display case against those shown in the wiring drawings for
proper wire position.

Each terminal can accept up to one #14 AWG (2.55 mm) wire, two #18 AWG (1.02 mm), or four #20 AWG (0.61 mm).

1. Strip the wire, leaving approximately 0.3 inches (7.5 mm) bare lead exposed (stranded wires should be tinned with solder).

2. Insert the lead under the screw-clamp terminal.

3. Tighten the screw-clamp until the wire is secure.

4. Pull the wire to verify tightness.

WIRING THE F6600 / F6650 SERIES DISPLAYS

The frequency signal from the Flo-tech FSC, FSB, and FSD series turbines is connected to the display using one of the
F2832 series cables. The Flo-tech Ultima sensor is connected using the F6234 series cables.

FSB, FSC*, and FSD Sensors

Connect the BLUE wire of the F2832 cable to terminal 5 (INPUT A) and the YELLOW wire to terminal 4 (COMM) on the F6600 series display.
See Figure 1.

* Some require the use of the F5140 K-Factor Scaler to ensure adequate signal strength to the display.

Ultima Sensors*

Connect the RED wire of the F6234 cable to terminal 5 (INPUT A) and the BLACK wire to terminal 4 (COMM) on the F6600 series display. See

Figure 1. The WHITE wire is not used.

* Some require the use of the F5140 K-Factor Scaler to ensure adequate signal strength to the display.

Signal Wiring, F6600 / F6650 and F6700 / F6750 Series Displays

WIRING THE F6600 / F6650 SERIES DISPLAYS
WITH F5140 KFACTOR SCALER

The Flo-tech FSC-375, F6202-F, and F6222-F turbines require the F5140 K-Factor Scaler to amplify the millivolt sensor output for transmission
to the F6600 series display. The turbines produce a low level signal so it is important to keep the F5140 K-Factor Scaler as close to the flow
sensor as possible. Close proximity will minimize signal interference and help eliminate erratic readings.

1. Feed the terminal end of the F2832 or F6234 cable through the wire bushing on the F5140. Insert the three-wire (customer supplied)
cable that will be used to bring power and return the output signal to the F6600 series readout. Tighten the wiring bushing.

2. Connect the BLUE wire from the F2832 or the RED wire from the F6234 cable to terminal 5 of the F5140 K-Factor Scaler. Connect the
YELLOW wire from the F2832 or the BLACK wire from the F6234 cable to terminal 6 of the F5140 K-Factor Scaler. See Figure 2.

4. Connect one of the wires from the customer-supplied cable to terminal 4 (+VIN) of the F5140 and note the wire color. Connect the other
end of this wire to terminal 3 (+12V DC) of the F6600 series display.

5. Connect one of the wires from the customer-supplied cable to terminal 2 (+OUTPUT) of the F5140 and note the wire color. Connect the
other end of this wire to terminal 5 (INPUT A) of the F6600 series display.

6. Connect the remaining wire from the customer-supplied cable to terminal 1 (-OUTPUT) of the F5140. Connect the other end of this wire
to terminal 4 (COMM) of the F6600 series display.

OTE:N A jumper wire is required between terminals 1 and 3 of the F5140.
