Pump/Remote Dispenser Wiring

Submersible Feed, Submersible Drive

This is a 120VAC input which 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 manual mode. When the reset finishes its cycle, the
120VAC 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

This is a 120VAC output which is used to indicate the reset is complete and the pump/remote
dispenser is ready to dispense 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
This is a 120VAC input which 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 only
be on when the pump/remote dispenser is authorized and the pump/remote dispenser should be
in the fast flow mode. This line will also be switched on when the pump/remote dispenser is in the
manual mode.


Light Feed

This is a 120VAC 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 the lights of up to 8 units can be supplied by one breaker. The light feed is not
controlled by the CFN System.


Light Neutral
This is a return line for AC current from the lights to the breaker panel.


Phase 2 Feed
This is a hot feed which is the opposite phase of the pump motor feed. This line and the pump
motor feed are used for 240VAC motor applications.


Pulser
This supplies a DC output which is provided to indicate the quantity dispensed. This line must be
capped when not in use. DC pulser and DC RS-422 and RS-485 communication wires can be
combined in the same conduit. DC wires must be in separate metal conduit from AC wires unless
shielded cable is used as specified in Section 3, RS-485, Short Haul Modems (RS-422), and
Pulser Wiring and Configuration.
