Neutral Feed
Neutral Feed is the AC current return line back to the breaker panel for all attached devices
(pump motor, reset motor, solenoid valves). The gauge of this wire must be equal to that of the
Pump Motor Feed (suction pumps) or Submersible Feed (remote dispensers).
Submersible Feed, Submersible Drive
Submersible Feed is a 120 VAC input that is supplied to the input side of one of the internal
switches of the electric reset. This line should be switched through the CFN System and only
be on when the pump/remote dispenser is authorized or in the manual mode. When the reset
finishes its cycle, the 120 VAC input to the switch is passed through as an output (submersible
drive) to drive a starter relay, or to directly drive a submersible motor up to 3/4 HP at
120/240 VAC or 1-1/2 HP at 240 VAC. Any submersible motor exceeding these limitations
must use a starter relay.
Note: 240 VAC is developed across a motor when the other leg of the motor is connected to a
Phase 2 Feed.
Reset Complete (Switch Detect)/Slow Flow
Reset Complete is a 120 VAC output that is used to indicate that the reset is complete and the
pump/remote dispenser is ready to dispense the product. Two lines are provided for twins.
This line should only be used when monitoring of the pump/remote dispenser is desired (such
as with a fuel management system). This line must be capped when not in use. This line is
connected to the slow flow stage of the solenoid in the pump.
Fast Flow
Fast Flow is a 120 VAC input that controls the fast flow valve of the pump/remote dispenser
(when a slow/fast flow valve is available). If slow/fast flow control is not desired, this line
should be tied to the Reset Complete/slow flow line. This line should be switched through the
CFN System and be on only if the pump/remote dispenser is authorized and the pump/remote
dispenser is in the fast flow mode. This line will also be turned on when the pump/remote
dispenser is in the manual mode.
Light Feed
Light Feed is a 120 VAC input required to power optional fluorescent lights that may be
available in a pump/remote dispenser. In a site configuration using multiple remote dispensers
(or pumps), the power for lights of up to 8 units can be supplied by one breaker. The light feed
is not controlled by the CFN System.
Light Neutral
Light Neutral is a return line for AC current from lights to the breaker panel.
Phase 2 Feed
Phase 2 Feed is a hot feed that is the opposite phase of the pump motor feed. This line and the
pump motor feed are used for 240 VAC motor applications.
