Troubleshooting Guide
To help field 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 briefly pushing the Silence
Button after each code is displayed until the Pump Status Display returns to normal status).

1. Push reset button on the EcoVFC.
2. If condition is corrected, check for proper operation of system; if
operating correctly do not continue to next step. If condition is still
present continue to next step.
3. Check SW3 Pole 6 setting and verify that it matches the
horsepower of the pump connected. Connecting VS2 motor with
a SW3 Pole 6 ON (4hp) setting, may cause this false indication
when operating in SW1 positions 0 - 6.
4. Check fuel level in storage tank; if product level is low schedule
fuel delivery, when delivery is complete and fuel level is above
PMA end bell, push reset button on EcoVFC Check for correct
system operation.
5. If condition is not corrected, it is possible that there is an
obstruction (rag or absorbent pad) on the inlet of the PMA.
LI Low
Incoming
Voltage
Voltage
fluctuations or
low input voltage.
1. Push reset button on the EcoVFC.
2. If condition is corrected, check for proper operation of system; if
operating correctly do not continue to next step. If condition is still
present continue to next step.
3. Use AC voltmeter to verify incoming voltage is within the 360-
440VAC acceptable range. If voltage is not within this range,
contact an electrician to correct problem.
LU Locked Rotor
fault at PMA
startup
Foreign material
in PMA or
defective PMA.
1. Push reset button on the EcoVFC.
2. If condition is corrected, check for proper operation of system; if
operating correctly do not continue to next step. If condition is still
present continue to next step.
PMA Inspection
3. Disconnect input voltage at load center, lock and tag circuit
breakers.
4. Remove two 9/16” bolts from extractable portion of the manifold.
Disengage the 3/4” securing bolt of the electrical connector and
swing out of the way.
5. Pull extractable part of the pump.
Note: Pump Motor Assembly shell can be damaged by blows from hard
surfaces; use care in removing it.
6. Remove black end cap from PMA and attempt to spin rotor with a
3/16" Allen wrench to determine if there is any binding. If binding
or physical damage, continue with next step. If no binding or
physical damage to the PMA, and it is a new installation, reinstall
extractable.
