Hardware Installation - Pulsers - NXFM100
• Do not attach AC power to the terminal marked "12V DC". This terminal is for DC powered 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 pulser wiring should be connected to the terminals 12, 13, and 14
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 'Pulse' - Terminal (13)
• Attach one wire to the terminal marked 'GND' - Terminal (12)
