CONTROL LINES
PURPOSE
This section is provided to familiarize the installer with the control inputs and outputs that are
available for the Series 9100Q 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 9100Q 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 9100Q 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; the Site Controller III Installation Manual, C35880; the
CFN Islander Installation Manual, C35520; or the TopKAT Installation Manual, C35754 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 to the
pump. It is possible to combine the pump motor feeds for twins and supply them from one
breaker; however, the gauge of the wire needs to be adjusted to handle the load of two motors.
