Fuel Control Panels
ISOFuel is a mechanical based isolation control system that simplifies the electrical installation of fueling equipment, it's custom built to ensure proper site operation with no wasted hardware - keeping size and price in mind, and it's built by electricians for electricians with the goal of providing a quick, easy and simple installation.
All the enclosures are built in house!

The ISOFuel Modules allows the user the ability to configure a fuel system to easily function with any ATG manufacturer and control any STP, whether they are using contactors, SC controllers or VFC drives.
E-STOP Module
​​
The E-STOP module provide the control power for all of the other modules. Each estop button will need to have a dedicated pair of #14 thhn conductors brought back to the ISOFuel panel. At the site, each estop button will need to be numbered so that in the event one is pushed the led, on the module will indicate which button is pushed. An estop reset button is located on the front of the panel and will need to be pushed to reset an estop environment.
The ISOFuel panel estop circuit is engineered to not drop out the emergency circuit in the event of power failure or brown out, meaning that when the power is restored the system will come back online without human intervention, unless an estop button was pushed during the outage.
Product Maintenance Switch
Product LED Indicator shows when a STP should be running
Purge Switch
Move the switch to the on position to purge the product lines.
Pump Control Dip Switches
The dip switches will be configured at the factory based on the order form we receive.
The top five switches turn on the 120 vac enable circuit for VFC’s and Smart Controllers in the on position.
The bottom five switches are used to determine if the STP is controlled by a VFC/Smart Controller or a contactor/motor starter.
Pump Control Module
The Pump Control Module receives up to five (05) product hook signals from each Dispenser Module via a T-BUSS which is the communication backbone for the modules.
When a dispenser receives a hook signal from a dispenser, it sends the signal to the Pump Control Module. The Pump Control Module sends 120 vac to the ATG as PI, if there is not a errors in the ATG for the particular product, the ATG will send 120 vac PO back to the Pump Control module. The pump control module will then enable the STP by one of the following: Pull in the STP contactor, send 120 vac enable to a VFC or send 120 vac enable to a Smart Controller (if required).
Each STP has a dedicated maintenance switch that will completely isolate the pump, drive or smart controller. Do not use the breaker as a maintenance switch, because voltage will still be present on the enable circuits. The ability to isolate all components for the STP’s circuit is a life safety feature of ISOFuel that competitors do not offer.​
Dispenser Module
​
Dispenser Module controls one dispenser. The maintenance switch will open all conductors going to the dispenser. The circuit for the dispenser, L1 and neutral, will connect to the module from the breaker.
The conductors that are connected from this module to the dispenser include:
-
L1 120 vac
-
Neutral
-
Product 1 Hook
-
Product 2 Hook
-
Product 3 Hook
-
Product 4 Hook
-
#14 thhn twisted pair for Data. If a signal cable with 300 volt insulation is used an Ethernet module will be required.
-
#14 thhn twisted pair for Crind. If cat 5 data cable used for Crind an Ethernet module will be required.
Low Voltage or ICOM Module
​
Low Voltage or ICOM module, it has up to four (4) connections in and out and up to two (2) ethernet connections in and out for cat 5 or 6, they are powered by the corresponding dispenser module.
By pressing the dispenser switches to the left, all wiring to the dispenser will be disconnected. This function follows NEC 2017 requirements for fueling equipment.
