Control Lines for Gasboy 9800 or 9820 Electronic Pumps/Dispensers System and Pump/Dispenser Wiring
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 230 VAC motor applications.
Pulser
This supplies a DC output which is provided to indicate the quantity dispensed.
Control Lines for Gasboy 9800 or 9820 Electronic Pumps/
Dispensers
Descriptions of the control lines are provided to familiarize the installer with the control inputs
and outputs that are used to control the Series 9800 and 9820 dispensing units. Reading these
descriptions will give the installer a better working knowledge of the system and aid in
planning the site wiring.
The Series 9800 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
International).
Ground
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 ground wire of the system 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).
Micro Feed
The Micro Feed is a 115 VAC (230 VAC International) input required to power the
microprocessor of the register’s electronics. This power must always remain on and must be
on a separate breaker from the control lines (Control/Pump Motor Feed or Control/Subm Feed
- Side 1, Side 2). This must also be on a separate breaker from the fluorescent lights to reduce
electrical noise and allow for separate control of the lights. In a site configuration using
multiple dispensing units, the power for the microprocessors of up to 8 units can be supplied
by one breaker.
Micro Neutral
The Micro Neutral is a return line for AC current from the microprocessor of the dispensing
unit to the breaker panel.
