How do I wire the pulser?
Please refer to this Pulser Troubleshooting Guide or the Pulser Compatibility Guide (each PDF will open in its own browser tab). Fill-Rite works with several pulser options. Each pulser varies slightly in terms of wiring.
Do I have to use the DAF relay on the NXFM100, or can I wire everything to the NXFM150?
You are welcome to use the NXFM150 to centralize all the wiring. It is required that the NXFM100 has power and a connection on the RS485 terminal. ⚠ Do not wire it in a way where the switch on the NXFM100 or NXFM150 needs to be left in bypass. This could burn out the relay.
What is the amp rating on the relay?
Fill-Rite relays are rated up to 30A. The units are shipped with 10A fuses. Please review the amp draw on the pump before firing up the system.
Must relay position #1 on the NXFM150 be used?
Yes. Relay 1 powers the rest of the board. This should be its own dedicated power supply.
Does the Fill-Rite system require a cellular network?
Fill-Rite transmits information and authorizes transactions using the cellular network of the device with the Fill-Rite app.
We do have an offline mode that is intended for temporary usage, not continual. This mode requires that the PIN be used when connected to the server, then it will work offline in the future.
You can also connect Fill-Rite to a local Wi-Fi network. This does require some custom configuration. Contact support@Fill-Rite.com for more information.
Does Fill-Rite work with Digital Dispensers?
Generally, Fill-Rite is not compatible with Digital Dispensers unless there is a pulse output board. Refer to our Pulser Compatibility Guide for further details. Generally digital dispensers communicate using the RS232 protocols. We do not currently directly interface with this communication platform.
What are the power supply options with Fill-Rite?
Fill-Rite works with 110, 220 and 12V DC Power supplies. We do not support 3 phase power. An external relay is required for 3 phase power to connect to Fill-Rite.
Does the Fill-Rite Circuit Board power the pulser?
Only DC Powered pulsers. There is a PWR terminal on the pulser connection; this is for DC Powered pulsers only.
⚠ AC powered pulsers must be connected to an external AC Power Supply. Connecting an AC Powered Pulser directly to the board will blow the circuit board. Wiring mistakes are not covered under Fill-Rite Warranty.
Can I mount the Tablet in landscape mode?
No. The Fill-Rite app does not scale to landscape mode. You must mount the tablet in Portrait mode (vertically).
Does the NXFM150 need power from the NXFM100?
No. The NXFM150 needs to be connected through the RS485 connection for communication. Each relay is powered independently. You will need input power for each relay. You can daisy-chain power on the NXFM150.
What kind of wire do I need to connect the NXFM100 and NXFM150?
Any twisted pair shielded wire. Cat 5 would work well, for example.
Can the NXFM100 be mounted in a metal box?
Yes, but you will need to make sure the Wi-Fi antenna is on the outside of the metal enclosure. It is recommended that Fill-Rite units be mounted away from any obstruction. Fill-Rite transmits its own Wi-Fi network and the signal could be obstructed by metal enclosures, walls, or concrete barricades.
Can I mount the Fill-Rite units in a pedestal?
Yes. Fill-Rite offers a Pedestal option to mount all units in a clean fashion. This makes running conduit a lot cleaner and easier. Refer to our install photos for examples.
Can a single conduit be run for all wiring?
No, it is required in the UL Standard that Pulse and Power conduit be run separately.
How long is the timeout after the fuel transaction is complete?
Default is 60 seconds. This can be configured on the Fill-Rite website under the Account Settings section. The timer can be configured from 30 seconds to 10 minutes.
Is there a handle detect?
Newer NXFM100 boards have handle detect on the single relay. However, the NXFM150 relays and older NXFM100 relays rely on the No Flow Timer or Disconnect button in the app to end the transaction and close the relay. Future NXFM150s will include a handle detect.
