Hardware Installation - Power On & Verification - NXFM150
After installing the Fill-Rite FMS hardware and restoring power to the pump, verify the
following items:
1. Power to the Hardware: (AC Power)
Check that the LEDs are illuminated on the Fill-Rite FMS circuit board. If the board
does not have power, check that the local circuit breaker has not tripped.
2. Bypass Mode:
Flip the bypass switch to "BYPASS" on the Fill-Rite FMS circuit board, and
confirm that your fuel equipment can dispense fuel. Be sure to switch to
"NORMAL ON" mode after you have successfully tested your equipment.
3. Hardware WiFi:
Ensure that your Fill-Rite FMS hardware is successfully broadcasting a wifi
signal. On a wifi-enabled device, you should be able to identify and join a wifi
network titled "NXFM_XXXXX", where XXXXX is the last five digits of the
device's serial number.
4. Test Transaction:
Have the Fill-Rite FMS administrator create a driver profile and pin code
for you, and perform a test fueling using the Fill-Rite FMS mobile app.
The Fill-Rite FMS app may perform a firmware update on first use.
5. Check Pulse Rate:
Confirm that the volume displayed on the Fill-Rite FMS app matches the volume of
fluid being dispensed by the equipment.
If the volumes do not match, go to fms.fillrite.com, select the site in question, click
on the configuration tab, and edit the pump/relay to update the pulse rate.

INSTALLATION AND OPERATION MANUAL
Hardware Installation - Pulsers - NXFM150
• Do not attach AC power to the terminal marked
"12V+". This terminal is for DC active pulsers
only. Attaching AC power to this terminal will
destroy your Fill-Rite FMS board.
The wiring configuration for pulsers depends on whether you are using a 2 wire pulser or
a 3 wire pulser. All Pump 1 pulser wiring should be connected to the terminals 31, 32, and
33 as demonstrated in the graphic below.
2-Wire Pulser:
For 2 wire pulsers, it does not matter which of the two wires you
attach to each terminal:
• Attach one wire to the terminal marked ENC INP - Terminal (32)
• Attach one wire to the terminal marked GND - Terminal (33)
3-Wire Pulser:
Use 3 wire pulser if pulser requires 12V DC power:
• Attach 12V power line from the pulser to the '12V DC' terminal - Terminal (31)
• Attach signal wire to the ENC INP terminal - Terminal (32)
• Attach the ground wire to the GND terminal - Terminal (33)
If using multiple NXFM150 Expansion
Modules, use the potentiomitor to
assign each box an address
