1. If applicable, please provide all alarm codes shown on the display (shown by scrolling to Display Screen #3).
You can also read the alarms on a PC using Fox's FT2A View™ software. Please visit the following URL to

2. Open the display by unscrewing the four phillips screws in the corners of the display of the FT2A. What is the
measured input power to the flow meter at the correct terminal for the input power type?
Acceptable voltages, terminal locations:
•
DC powered: 24VDC (±10%), terminal TS1 pins 1 (+) and 2 (-)
•
AC powered: 100 to 240VAC, terminal TS7 pins 1 and 2
•
3. Test/Check the fuse in the FT2A.
With the power off, take a resistance measurement across the fuse to ensure it is a short circuit.
•
Acceptable resistance: <1 ohm.
•
4. Test/Check the LED status (Heartbeat) light of the FT2A. Is the LP1 LED (green) blinking once per second?
The LP1 status LED (green) light can be viewed by opening the enclosure.
•
Is the Power LP4 LED (orange) emitting a steady orange light?
•
5. For remote sensor configurations (see images on next page):
If the sensor is remote from the electronics, please provide the length and gauge of the wire/cable
•
connecting the sensor junction box to the electronics housing.
The serial number on the electronics housing must match the serial number on the probe/sensor
•
assembly. It is a common mistake to mix the serial numbers when multiple meters with remote electronics
are ordered. Please confirm the probe serial number is the same as on the electronics housing.
Carefully check for proper wire terminations at the sensor junction box and at the electronics housing.
