Hardware Migration

Fuellox V1 to V2 Hardware Migration

This section provides a detailed overview of the process for migrating a Fuellox unit from V1 hardware to the updated V2 hardware platform.

Note

• V1 refers to the older hardware version.
• V2 refers to the newer hardware version.

Electrical Hazard

Installation of 240V AC systems must be carried out by a licensed electrical contractor.

In many cases, the original Fuellox V1 system operates on low voltage DC. In such instances, migration tasks may be performed by personnel with appropriate DC or automotive electrical experience.

Note

Fuellox systems are covered under warranty. However, if components are damaged due to incorrect wiring or installation errors, the cost of replacement parts will be charged to the customer.

For Fuellox V1 and V2 wiring details, refer to the Fuellox Fuellox Wiring Diagram and Board Details.

Main Power Supply

Relocate the 12V DC power supply to the designated input on the new Fuellox unit.

V1 Jumper	Description	V2 Jumper
J8-3	None	N/A
J8-2	GND / 0V	J9-1 Black
J8-1	+VBAT	J9-2 Red

Pulse Meter

Pulse meters may be either Hall Effect (3-wire) or Reed (2-wire) types.

To migrate the pulse meter to the V2 hardware, simply reconnect the wires to the corresponding V2 input terminals as outlined below.

V1 Jumper	Description	V2 Jumper
J5-1*	Meter Power 12V (Hall Effect only)	J18-2
J5-2	Pulse Signal	J18-3
J5-3	0V	J18-4

Note

Meter power will be 12V, provided the board input power is also 12V. In some setups, the board may operate on 24V.

Caution

Some meter models strictly require a 12V supply. Always confirm your meter’s voltage requirements before connection.

Installation Tip

To avoid damage or stress, ensure the meter is securely mounted so it does not bear the weight of the hose or absorb any shocks from hose movement.

EStop

Note

Please confirm that the wiring table is correct by reviewing the existing connections. Always test the system thoroughly before commissioning to ensure proper functionality and safety.

V1 Jumper	Description	V2 Jumper
J4-1	E Stop NO	J11-2
J4-2*	0V	J11-6 or J11-5
J4-3	E Stop NC	J11-3
J4-4	0V	J11-6 or J11-5

In certain setups, Emergency Stops (EStops) may include additional control features. For example, an EStop may incorporate extra contacts that isolate a relay, disconnect the main power supply to the pump, or interrupt the power between the relay and the pump.

Pump Control

In Fuellox V1, the 12V DC supply to the pump is routed through the Fuellox relay.

The right-hand side (RHS) of the relay serves as the power supply input. If the supply is not present, Jumper SK-4 provides a 12V DC low-current feed to this side of the relay.

The left-hand side (LHS) functions as the switching load. When Fuellox authorizes a transaction, this output delivers a switched 12V DC supply.

V1 Jumper	Description	V2 Jumper
J19-1	Switching Active	J12-4
J19-2	Pump Relay Supply	Not Required
J19-2	Pump Relay GND	J12-3

Note

The supply may connect to a pump, relay, or contactor.

If an additional relay is provided (e.g., FLX-V2-MINI-R), refer to the drawings and image here for further guidance.

Nozzle Switch

Relocate the nozzle switch wiring to the updated terminals as outlined below:

V1 Jumper	Description	V2 Jumper
J6-1	Nozzle Supply	J11-1
J6-2	0V	J11-6 or J11-5

Level Transponder

Reassign the level probe connections to the new terminals as detailed below:

V1 Jumper	Description	V2 Jumper
J17-1	Level Supply	J17-1
J17-2	4-20mA signal	J17-2

Note

Fuellox V2 introduces updated requirements for level configuration, including the need for a new strapping table. For assistance with enabling the updated level table, please contact the Fuellox Help Desk

Updated Level Table Requirements

Once the wiring is complete and the system is operational, please prepare the following information for the Fuellox Help Desk:

1. Current tank level in millimetres (mm)

2. Current tank level in litres

3. Maximum liquid height (safe fill level) as measured from the dipstick

4. Record 3–5 reference points from the dipstick, noting the corresponding tank levels in litres and millimetres

Be sure that Fuellox Level is enabled for the specific hardware unit.

Contact the Fuellox Help Desk with the collected data. They will use this information to configure the necessary backend updates.

Updating Fuellox V2 Hardware Configuration

To update the Fuellox V2 hardware configuration, make sure you are within range of the device and that it is powered on throughout the process.

In the Fuellox App:

Step	Description	Check
1	Login to the app and press Sync	☐
2	Resellers Only: If you can access > 1 Org, select your Tenant/Org from the menu first	☐
3	Click Hamburger Menu	☐
4	Manage Devices (you may need additional permissions in the app for this)	☐
5	Click the BLE switch next to the search, and your device should be listed	☐
6	Tap the new Fuellox V2 device in the list	☐
7	Click Retry if the connection is not successful	☐
8	Go to the Config section	☐
9	Scroll down through the config	☐
10	Turn on the switching requirements you have	☐
11	Set the Pre and Post flow timers	☐
	For Systems with a level unit only:
12	Turn on the Level Unit	☐
13	Enter the Max mm	☐
14	Enter the Max 4–20mA (17 for a 2.7m high tank)	☐
	For all systems:
15	Click Save. Wait for the 2× green notifications	☐
16	Power off the Fuellox V2	☐
17	Wait 2–3 mins. Be sure the power supply has fully discharged	☐
18	Power on the unit	☐
19	Complete a transaction	☐
20	Verify the nozzle switch is working	☐
21	Verify the EStop is working	☐
22	Verify the pre flow timer is working	☐
23	Verify the post flow timer is working	☐
24	Confirm with the help desk the migration is completed and successful	☐
	If installed:
25	Confirm the tank level is reported	☐
26	Verify with the help desk the Level is reporting and the strapping table has worked	☐

Ongoing Level Measurement

It is recommended to periodically compare the tank level reported by Fuellox with actual dip stick measurements. If discrepancies are observed, notify the help desk with a new calibration point, including the measured height in millimetres and the corresponding tank volume.

Providing accurate readings from both the high and low points of the tank will significantly enhance the accuracy of level reporting.

Make sure about the consistent and reliable performance, verify dip readings before and after the next 2–3 deliveries.
