Section 3
CONTROL LINES
PURPOSE
This section is provided to familiarize the installer with the control inputs and outputs that are
available for the Series 9100A dispensing unit. It is recommended the installer read these
descriptions to obtain a better working knowledge of the unit in order to guide him in planning the
site wiring. Reference Section 4 for specific wiring diagrams and installation notes.
The Series 9100A may be provided for use with 230 VAC power for international applications.
The operating voltage for control lines to these units is shown in parentheses as (230 VAC Int'l).
If connecting the 9100A to a GASBOY fuel management system, refer to the Series 1000
Installation Manual, C08922; the CFN Site Controller I Installation Manual, C01917; the Site
Controller II Installation Manual, C01918; or the CFN Islander Installation Manual, C35520; for
installation information.
GROUNDING
To ensure proper operation of the equipment and provide the necessary safety factors, a good
ground line must be provided. A ground wire (preferably green) must be connected between the
unit's AC junction box ground lug and the main electrical service panel. One (1) earth ground
connection is required per unit. The ground rod is to be a solid, corrosion-resistant conductor
and must be installed at the main electrical panel in accordance with the National Electrical Code.
It should be properly tied into the ground bus strip of the panel. We recommend the neutral and
ground bus strips be bonded together (unless prohibited by local codes).
RESET MOTOR FEED
The reset motor feed is a 115 VAC (230 VAC Int'l) input which is supplied through the pump
handle switch to activate the reset motor. Without power 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 Int'l) 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 Int'l).
PUMP MOTOR FEED
The pump motor feed is a 115 VAC (230 VAC Int'l) input which is 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 Int'l) input to the switch is passed through as an output causing the pump motor to
receive power and begin running. Without power to this line, the unit would reset, but be unable
to fuel. Two feed lines are provided in twins which contain two motors. The gauge of this wire
(and its neutral wire) should be determined according to the size of the motor, the voltage at
which the motor will be powered (115VAC or 230VAC), and the distance from the breaker panel
