Important Safety Messages
FE Petro equipment is designed to be used to pump volatile hydrocarbon liquids such as gasoline and diesel fuel.
Installing or working on this equipment means working in an environment in which these highly ammable liquids are
present. This presents a risk of severe injury or death if these instructions and standard industry practices are
not followed. Read and follow this entire instruction booklet before installing or working on this equipment.
As you read these instructions, watch for the following safety symbols:
Follow all federal, state, and local laws governing the installation of this product and its
associated systems. When no other regulations apply, follow NFPA codes 30, 30A, and 70 from
the National Fire Protection Association. Failure to follow these codes could result in severe
injury, death, serious property damage and/or environmental contamination.
ALWAYS tag and lock breakers so they are not turned on accidentally. If the electrical circuit
breakers are accidentally turned on while the pump is being installed or serviced, electrical
power could be applied to the pump, creating the risk of a potentially lethal electrical shock
hazard and the possibility of an explosion or re from a spark which could ignite hydrocarbon
vapors present during IST installation.
After disconnecting power to the EcoVFC, wait one minute after LED display blanks before
opening the cover for servicing. Voltage stored in the capacitor bank of the EcoVFC presents a
risk of potentially lethal electrical shock even after power is disconnected.
Install this unit only in a non-hazardous area. This equipment is connected to devices located
in hazardouls locations with highly ammable vapors present. Failure to follow all safety could
result in serious re or explosion.
Before entering a containment sump check for the presence of hydrocarbon vapors. If
hydrocarbon vapors are at unsafe levels, ventilate the sump with fresh air, re-check the
atmosphere before entering the sump and periodically thereafter. ALWAYS have a second person
standing by for assistance when working in or around a containment sump. Many submersible
pumps are now housed in containment sumps designed to trap hazardous liquid spills and
prevent contamination of the environment. These containment sumps can also trap dangerous
amounts of hydrocarbon vapors which, if inhaled, could lead to dizziness and fainting, or, if
ignited, could result in an explosion causing serious personal injury or death.
Always disconnect both power supplies (the 110-240 VAC from dispenser hook signals and the
360-440 VAC input power supply) before installing or servicing this system. Failure to do so
could result in death or serious bodily injury.
Installer: This instruction booklet MUST be left with the owner of the service station at which the equipment is being
installed.
Station Owner: Retain these instructions for future use and provide them to persons servicing or removing this
equipment.
Note: Always refer to the Installation and Owner’s Manual that came with the equipment for the most current and
complete list of installation and safety precautions. Where applicable, this manual may also contain notations on
equipment features present in software version 1.14 and higher.
This symbol identies a potentially hazardous situation which, if the instructions that follow it are not adhered
to, could result in death or serious bodily injury.
This symbol identies a potentially hazardous situation which, if the instructions that follow it are not adhered
to, could result in serious property damage, including possible environmental contamination as a result of
the leakage of fuel from the equipment.

Installation Instructions
Note: Steps 1 through 3 are also part of the installation
instructions for the submersible pump. This is done
to make sure all instructions are available if needed
during installation. As a result, steps 1-4 may
already be complete.
1. Connect the electrical conduit with approved
ttings to the submersible pump junction box.
2. Remove the submersible pump junction box cover,
and remove the compression seal by loosening
the screw (do not remove the screw). The seal
has four holes to accommodate a ground wire and
three-phase power from the EcoVFC.
Not installing a ground wire increases
the risk of potentially lethal electrical
shock and equipment failure. All holes
of the compression seal (contractors
plug) must be lled with wires or a
Celcon®rod to enable it to seal.
3. Verify that the power is OFF at the supply box.
Pull four wires from the spot where the EcoVFC
unit will be mounted into the submersible pump
junction box and feed through the compression
seal. Slide the compression seal into place and
tighten securely. Connect the three wires from
the connector assembly to the three phase
power wires coming from the EcoVFC. Connect
the fourth wire (ground) from inside to the pump
junction box ground lug. EcoVFC accomodates
type TT or TN grounding congurations.
Note: All wiring must conform to all applicable guidelines
in accordance with all federal, state, and local
codes. Failure to comply with all applicable
guidelines could result in an unsafe installation.
Use the following table for maximum wire length to
wire gauge for submersible wiring:
Wire Size Maximum Run
5.26 mm2(10 AWG) 200 meters (650 feet)
3.31 mm2(12 AWG) 120 meters (400 feet)
2.08 mm2 (14 AWG) 75 meters (250 feet)
4. Replace the cover of the pump junction box and
securely tighten in place.
The compression seal is not a
replacement for the vapor explosion
seals required by the NEC. All materials
used between the power supply box
and the submersible pump junction
box must be gasoline and oil resistant.
All wiring used within the EcoVFC must
be rated 90°C, 600V minimum. Failure
to comply with these, and all applicable
NEC guidelines, could result in an
unsafe installation.
5. Hang the EcoVFC on a vertical surface and
remove the front panel screw and front cover.
Install approved electrical conduits only at factory
knockouts on the EcoVFC enclosure.
Note: Interference is created by several types of
equipment in a station (uorescent lighting,
compressor, etc.), some more than others; this
interference can affect the operation of more
sensitive equipment (such as tank monitors and
electronic line leak detectors) which communicate
through data lines. When installing the EcoVFC,
FE Petro recommends that the power wires from
the Power Source as well as the power wires
to the IST or STP units with VS2 or VS4 sufx
(pump) be in their own steel conduit which is not
broken or routed through race ways. FE Petro also
recommends that all equipment be installed per the
manufacturer requirements for best results.
Note: The EcoVFC must be mounted indoors in a non-
hazardous location with ambient temperatures
between 4° C (40° F) and 35° C (95° F).
The EcoVFC measures 36.2cm (14.25”)H x 14.25cm
(5.50") W x 24.1cm (9.50") D (Figure 3 ).
Note: To allow room for eld adjustments and air
clearance, mount the controllers so they have 6” or
more of clearance on the top, bottom and right side
(cover side) , and 3" or more clearance on the left
side (heat sink side) . Install with the heat sink ns
vertical and the knock-outs down.

6. Refer to Figure 1. Connect the three motor control
wires from the pump junction box to labeled
terminals observing color coding of wires (Black to
Black, Orange to Orange, Red to Red). Connect
the ground wire from the submersible pump to the
ground lug on the EcoVFC circuit board.
To avoid the risk of potentially lethal
electrical shock, re, or explosion,
always tag and lock circuit breakers
in the off position before opening the
EcoVFC.
After disconnecting power to the
EcoVFC, wait one minute after LED
display blanks before opening the
cover for servicing. Voltage stored
in the capacitor bank of the EcoVFC
presents a risk of potentially lethal
electrical shock even after power is
disconnected.
Note: If the motor power wires are not connected with
the proper polarity, the motor will run in reverse
rotation causing output pressures of approximately
1.2 - 2.0 bar (17-29 psi) with a PMA VS4 and
approximately 0.7 - 1.2 bar (10-18 psi) with a PMA
VS2 connected.
7. Connect three phase, 360-440V, 50 or 60Hz power
supply to terminals to N, L1, L2 and L3. Reference
Figure 1 for wiring details.
Note: The EcoVFC must be connected to three-phase
power only. If 200-250V, 50 Hz, Single Phase
power supply is only available, the EcoVFC must
be replaced with the FE Petro MagVFC, which
will olny be capable of driving a PMA VS2 in this
application.
Do not connect incoming power to
any terminals other than L1, L2, and
L3. Connecting input power to any
other terminals will cause failure and
permanent damage to the EcoVFC.
There must be NO hook signal present
when applying power to the controller.
8. Connect dispenser hook signal to the two position
terminal block on the EcoVFC board as shown in
Figure 1.
Note: Dispenser hook terminals are capable of accepting
voltages from 110 VAC through 240 VAC
dispenser signals. The dispenser hook terminals
require a signal wire from the dispenser and a
Neutral / Return.
9. Conguration switches are factory set for PMA
VS2 in gasoline, mechanical leak detectors,
extended run active, and stand-alone operation
as detailed below in Figure 4. If you are using
a different conguration see the Option Select

needed.

8
SW6 Poles 6 - 8
These switches are not used. Leave them in
the OFF position.
Note: EcoVFC may operate in an unpredictable manner if
any of the switches, SW6 Poles 6-8, are in the ON
position.
11. Replace the cover of the EcoVFC.
12. Insert a 0 - 7 bar (0 -100 psi) pressure gauge into
the 1/4” line test port of the submerged pump
(or other pressurized test location in the piping
system). Turn power on to the EcoVFC at the
load center, turn on the submerged pump at the
dispenser and inspect the line test port for leaks.
If there are any leaks, immediately turn off the
submerged pump at the dispenser and the load
center and repair the leaks.
13. Begin purging the air from the piping system by
activating a dispenser handle and pumping product
into an approved container. Verify that while the
pump is on but no product is being dispensed,
the pressure reading on the gauge is equal to the
related pressure from Table 4 in Step 22,
+0.3 / -0.5 bar (+5 / -7 psi).
Note: If pressure in the piping system is much lower than
selected, it is possible that the polarity of the motor
power wires is not correct, causing the motor to
run in reverse rotation. Turn off the pump at the
power supply, (wait one minute after LED display
blanks before opening the cover) and change the
connection of any two wires at the pump or at the
EcoVFC motor terminals. Turn the pump back on
and read the pressure gauge again. The electrical
connection, which gives the higher reading on the
pressure gauge, is the correct one.
14. Complete purging the remaining air from the piping
system and dispensers. If using Master-Slave or
Master-Slave/Alternating Circuit, continue with
next section. If not, go to “EcoVFC Site Set-Up”
section.
Master-Slave Control Connections
Note: For Master / Slave and Alternating congurations,
the EcoVFC can only be paired with other
EcoVFC’s. Because of enhanced communication
protocols, the EcoVFC is not capable of
communication with the IST-VFC unless SW6 Pole
3 (IST-VFC Compatibility Mode) is switched ON.
IST-VFC Compatibility Mode is available in rev 1.18
software or higher EcoVFCs.
To avoid the risk of potentially lethal
electrical shock, explosion or re,
always tag and lock circuit breakers
in the off position before removing the
cover of the EcoVFC.
After disconnecting power to the
EcoVFC, wait one minute after LED
display blanks before opening the
cover for servicing. Voltage stored
in the capacitor bank of the EcoVFC
presents a risk of potentially lethal
electrical shock even after power is
disconnected.
15. When two IST pumps or STP units with VS4
or VS2 sufx are installed to be run in parallel
(discharging into the same line) three different
modes of operation are possible, as follows:
Master – Slave
When a hook voltage is present at the Master it will turn
on. When demand for product increases (more nozzles
open) the Master will call the Slave controller to turn on.
This will maintain the product ow rate in high demand
situations. In this conguration, the slave unit(s) will run
only when requested to do so by the master unit.
Alternating Circuit
The controllers will rotate being the one to turn on as the
hook voltage turns on and off. Only one controller is on
at a time in this conguration. Not available in IST-VFC
Compatibility Mode.
Master – Slave and Alternating Circuit
A combination of the above two congurations. The rst
controller to turn on rotates and when the demand for
product increases, additional controllers will be called on to
assist.
See Figure 5 wiring diagram for the RS485 connections.
16. For Master – Slave Conguration (not applicable
to IST-VFC Mode)
Set Master SW3 Pole 3 to ON, SW3 Pole 8 to
OFF,and verify that on SW2 all switches are
OFF.
Set Slave(s), verify that SW3 Pole 3 and SW3
Pole 8 are set OFF (factory default). Set SW2
switches of Slave(s) per Table 1.
Warning
Warning

9
For Alternating Circuit Conguration (not
applicable to IST-VFC Mode)
Set Master SW3 Pole 3 to OFF, SW3 Pole 8
to ON and SW2 switches all OFF
For Slave(s), SW3 Pole 3 is set OFF (factory
default), SW3 Pole 8 to OFF and SW2 switches
per Table 1.
For Master – Slave and Alternating Circuit
Conguration (not applicable to IST-VFC Mode)
Set Master SW3 pole 3 and SW3 Pole 8 are
ON and SW2 switches all OFF
For Slave(s), SW3 Pole 3 and SW3 Pole 8 are
OFF and SW2 switches per Table 1
Note: For IST-VFC Compatibility Mode (SW6 Pole 3 ON),
set Master SW3 pole 3 ON, set Slaves(s) SW3
pole 3 OFF, and set SW2 switches per Table 1A.
Line leak detection performance can be
affected when using multiple EcoVFCs.
FE Petro does not recommend using
the Alternating Circuit feature in
conjunction with electronic line leak
detection. Some electronic line leak
detector manufacturers require that
the Master turn on rst all of the time.
Please refer to the manufacturer’s
requirements.

all controllers. Required setting for VR PLLD.
OFF an alarm condition will shutdown only the
controller with the alarm. (factory setting)
When this option is selected, switch ON, the entire system
will shutdown if any of the controllers, Master or Slaves,
alarms. The system will not run until the alarm is corrected
and the reset button is pushed or the Fault Shutdown
option switch is turned OFF and the reset button is pushed.
18. Wire the RS485, connecting the master EcoVFC
to the slave(s) EcoVFC as shown in Figure 5. Wire
per NFPA 30A, and NFPA 70. For the signal wires,
use at least 0.326 mm2(22 AWG) (600V minimum)
4 conductor shielded cable with a drain and within
a common jacket. Cut wires to length so that
there is no excess wiring touching circuit board
components.
Note: When wiring a Master - Slave and / or Alternating
Circuit set, connect the signal from the dispenser
(hook) to the terminals of the Master EcoVFC only.
The Master controller will energize the Slave(s)
when needed without a signal from the dispenser.
19. When all connections are complete, reinstall the
EcoVFC covers and activate supply power. Verify
that the front panel status indicator is displaying Id
(Idle) for both Master and Slave(s)
No te: When working with a Master-Slave or Master-Slave/
Alternating Circuit conguration, there can be one
Master and up to (31) slaves. When connected properly,
the yellow Communication LED will ash quickly on the
Master unit and ash in sequence through the Slave
unit(s). See Figure 2 for LED location.

EcoVFC Proportional Alternating Circuit
Feature (Software Version 1.24)
To enable the Proportional Alternating Circuit feature on the
EcoVFC with software version 1.24 or higher:
Set SW3 position 8 to the ON Position.
Set SW6 position 4 to the ON position. This activates
the timed alternating circuit mode. This switch
needs to be enabled on the master EcoVFC only.
Set SW6 position 5 to the ON position. This switch
activates the proportioning feature and needs to be
enabled on the master EcoVFC only.
Set SW2 to the desired address for pump run time.
Each EcoVFC address will be set based on the
time it needs to run (Table 3).
Note: This is different from the typical Master EcoVFC
address of “0” (See gure 6 for switch locations).
Example:
• For a Master controller with a 20,000 gallon tank,
when set to address 20 the pump will run for 30
minutes.
• For a Slave controller with a 12,000 gallon tank,
when set to address 12 the pump will run for 18
minutes.
• For another Slave controller in an 8,000 gallon
tank, when set to address 8 the pump will run for 12
minutes.
Any address can be set, as long as the addresses are
unique between controllers. Typically addresses and
run times will be chosen that are proportional to the tank
sizes. The example shows 3 different size tanks and the
addresses that run the pumps in proportion to the tank size.

EcoVFC SITE SET UP
20. Verify rotary switch on EcoVFC is set to
position 4. This will provide approximately 2.2 bar
(32 psi) output from the IST or STP units with VS2
or VS4 sufx, and serves as a good starting point
for EcoVFC calibration.
21. Using a 19 liter (5 gallon) capacity minimum
approved container, go to the dispenser closest
to the storage tank and perform a Flow Rate Test.
If the product being pumped is gasoline, consider
following the U.S. EPA Fuel Dispenser Flow Rate
Test Procedure for 38 LPM (10 GPM) maximum
ow rate standard, where applicable.
Note: It is necessary to perform a Flow Rate Test for each
product available at the dispenser. This will conrm
that all product outputs, including products blended
at the dispenser, do not exceed the U.S. EPA 38
LPM (10 GPM) maximum, where applicable.
Note: Use of “ow restrictors” to control a maximum ow
rate of 38 LPM (10 gpm) per nozzle (as required
by the U.S. EPA) are not required if the variable
frequency controller is properly calibrated as
dened in “EcoVFC Site set up Section” section.
22. If output is above or below the desired range (i.e.
30 -38 LPM or 8-10 GPM), turn off the pump at the
power supply, (wait one minute after LED display
blanks before opening the cover) remove the
EcoVFC cover, and adjust the rotary switch (SW1),
see Figure 2. This switch will increase or decrease
the system operating pressure according to Table
4. An increase in pressure will normally yield an
increase in ow rate; a decrease in pressure will
reduce ow rate. Replace the EcoVFC cover and
re-apply input voltage. Return to Step 21 above
and check LPM (GPM) with the new settings.
Repeat until the output obtained is within the
desired range in LPM (G PM).

Table 4: SW1 Settings
To avoid the risk of potentially lethal
electrical shock, explosion or re,
always tag and lock circuit breakers
in the off position before removing the
cover of the EcoVFC.
After disconnecting power to the
EcoVFC, wait one minute after LED
display blanks before opening the
cover for servicing. Voltage stored
in the capacitor bank of the EcoVFC
presents a risk of potentially lethal
electrical shock even after power is
disconnected.
Note: Additives in gasoline can change the specic
gravity of gasoline, which may cause the pressures
stated in the above Table 4 to vary.
23. Optimize Pipe Compensation settings by doing
another Flow Rate Test; this time with two other
nozzles from the same product open at the same
time as your test nozzle. If the ow rate at the
test nozzle falls from the desired range with three
nozzles open, increase SW3 pole 4 and pole 5 to
the next highest compensation setting (0 to 1 or
1 to 2 for example). If output exceeds the desired
range, decrease to the next lowest compensation
setting (2 to 1 or 1 to 0 for example). Repeat this
step until compensation setting is optimal for your
installation. Factory setting is zero.

Display Denitions
The EcoVFC is equipped with a display that indicates several operating parameters of the EcoVFC as well as
indicates an error code when a fault is detected. When the EcoVFC is in an error condition, the alarm code will
be displayed. The alarm code denitions and proposed troubleshooting methods are in the Troubleshooting
section of this manual.

Troubleshooting Guide
To help eld service personnel, the EcoVFC can diagnose abnormal operating conditions, and communicate them via the
display on the front panel. The display indicates the operating status of the controller and, if an alarm is present, displays
the alarm condition. The following tables show the alarm codes, as well as provide suggested troubleshooting steps.
The EcoVFC is also equipped with a Reset Button to clear faults and a Silence Audible Alarm Button that turns off the
audible alarm when depressed. Depressing the silence audible alarm button does not clear the fault; it only silences the
alarm. Pushing and holding the Silence Button will put the Pump Status Display in fault readout mode, showing the last
3 fault conditions encountered by the EcoVFC, ie. F0 is followed by the code of the last fault encountered, F1 is second
to last fault encountered, F2 is third to last fault encountered (sequence through the codes by briey pushing the Silence
Button after each code is displayed until the Pump Status Display returns to normal status).

EcoVFC/PMA Connections
1. Disconnect power at load center, lock and tag circuit
breakers.
2. Remove the three motor control outputs from the
EcoVFC unit.
3. Using an ohmmeter on 200 Ω setting, place leads
between these three wires from the pump motor, this is
the rst step in determining where the open circuit has
occurred. Correct reading between any two of the three
wires should be 1.2 + / -1 ohms for a VS4 and 2.5 + / -1
ohms for a VS2.
4. Continue conductivity tests on the remaining
combinations of wires (3 total). Note results, e.g. Black
to red = 2 ohms. Readings between any of the three
motor control wires and ground should be an open
circuit. If readings in this step are incorrect go to Step
7; if readings are correct, contact FE Petro Technical
Support for assistance.
5. Go to the submerged turbine and remove the cover at
the top of the extractable manifold; remove the three
wire nuts.
6. Place an ohmmeter between the three wires leading to
the pump motor as above. If readings are incorrect go
to PMA replacement in 3 ashes section; if readings are
correct, there is problem with the wiring between the
EcoVFC and this point.
7. Remove the junction box cover and do conductivity
test on wires from junction box to extractable discharge
head. If wires are not conducting replace the male and
female connectors of the submerged turbine. If there is
no problem with these connections the wires from the
EcoVFC to the submerged turbine are suspect. Contact
an electrician to correct the problem.
8. After the problem has been corrected turn on power to
EcoVFC and verify system is operating correctly.
Note: In rare installations where motor wiring runs are extremely long and/or of a small wire diameter, a false
OC (open circuit) may be displayed on the EcoVFC. See the table of recommended maximum wire length

between any two of the three wires should be 1.2 + / -1 ohms for
a VS4 and 2.5 + / -1 ohms for a VS2.
4. Continue conductivity tests between each of the three motor
control wires and ground. If readings are greater than 80k Ω
proceed to Step 8. If readings are less than 80k Ω the possibility
of a short circuit in the connections from the EcoVFC to PMA
exists.
5. Go to the submerged turbine and remove the cover at the top of
