Reset Motor Feed
The reset motor feed is a 115 VAC (230 VAC international) input supplied through the pump
handle switch to activate the reset motor. Without power being supplied to this line, the unit
will not reset when the pump handle is turned on. Two feed lines are provided for twins. This
feed is also connected to the input of one of the internal switches of the electric reset. When
the reset finishes its cycle, the 115 VAC (230 VAC international) input to the switch will be
passed through as an output, causing the solenoid valve (optional in some models) to open and
the reset complete line to indicate 115 VAC (230 VAC international).
Pump Motor Feed
The pump motor feed is a 115 VAC (230 VAC international) input supplied to the input side of
one of the internal switches of the electric reset. When the reset finishes its cycle, the

115 VAC (230 VAC international) input to the switch is passed through as an output, causing
the pump motor to receive power and begin operation. Without power to this line, the unit will
reset and will be unable to fuel. Two feed lines are provided in twins that contain two motors.
The gauge of this wire (and its neutral wire) must be determined according to the size of the
motor, the voltage at which the motor will be powered (115 VAC or 230 VAC), and the
distance from the breaker panel to the pump. It is possible to combine pump motor feeds for
twins and supply them from one breaker. However, the gauge of the wire must be adjusted to
handle the load of two motors.
Return (Neutral)
The return is the AC current return line back to the breaker panel for all attached devices
(pump motor, reset motor, and solenoid valves). The gauge of this wire must be equal to that of
the pump motor feed (suction pumps) or submersible feed (remote dispensers). This wire is
commonly referred to as the neutral wire.
Submersible Feed, Submersible Drive
The submersible feed is a 115 VAC (230 VAC international) input supplied to the input side of
one of the internal switches of the electric reset. When the reset finishes its cycle, the

115 VAC (230 VAC international) 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 one
HP at 115 VAC/230 VAC. Any submersible motor exceeding this limitation must use a starter
relay.
Reset Complete (Switch Detect)/Slow Flow
The reset complete is a 115 VAC (230 VAC international) output used to indicate that the reset
is complete and the dispensing unit is ready to dispense the product. Two lines are provided for
twins. Use this line only when monitoring a dispensing unit that is connected to a FMS. This
line must be capped when not in use, and is connected to the slow-flow stage of the solenoid in
the pump.
