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 Eco VFC circuit board.
To avoid the risk of potentially lethal
electrical shock, fire, 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. Configuration 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 configuration see the Option Select
section of this manual.
