Wiring Your NXFM150 Pulser

You are here:

⚠ Warning: 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 board.

The wiring configuration for pulsers depends on whether you are using a passive pulser or an active pulser. All pulser wiring should be connected to the terminals 7, 8, and 9 as demonstrated in the graphic below.

2-Wire (Passive) Pulser

Note: 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)

  • Attach signal wire to the ENC INP terminal – Terminal (32)
  • Attach the ground wire to the GND terminal – Terminal (33)
