SYSTEM OVERVIEW
THE SERIES 1000 SYSTEM
The GASBOY Series 1000 Fuel Management System is a microprocessor-based fuel control and
data acquisition system which provides cost-efficient, 24-hour, unattended access to fuel
dispensing equipment. The system is Underwriter's Laboratories (UL) and FCC listed. The
Series 1000 system can be ordered in one of three system configurations: card, where access to
the system is controlled by magnetic or optical cards; cardless, where access to the system is
attained by entering a valid vehicle number; or FleetKey, where access to the system is controlled
by encoded data keys.
All system types have the same basic design, however, the head differs for each system type and
the pedestal dimensions are different with the receipt printer option. Throughout this manual,
references are made to each of these system types. Be sure to read the information for the
pertinent system type.
The system is modularly designed and easy to service. Access to the system is afforded via a
hinged door at the rear of the cabinet. The one-piece hood can be removed for total accessibility
during servicing.
ABOUT THIS BOOK
This book was written to assist the authorized service representative (ASR) or technician in
troubleshooting the Series 1000 system. The book is broken down into sections, one for each
component. Each section consists of:
● a description of the component
● a visual layout
● wiring connections
● illustrations of the programmed circuit boards and their indicators, connectors, jumpers, and
switches
● diagnostic test procedures
● a troubleshooting section
USING THE TROUBLESHOOTING SECTION
The Troubleshooting section for each component lists system problems, probable causes and
corrective action to be taken. The probable causes and checks for each problem are presented in
logical sequence allowing you to rule out one set of symptoms before proceeding to the next.
A double line at the end of a problem sequence indicates the last of the checks for that problem.
If your system still is not working, recheck your symptoms and follow another problem sequence,
if necessary. If you encounter problems you cannot solve by using this manual, call GASBOY
technical service at 1-800-444-5529.
Checks and corrective actions requiring voltage measurements assume familiarity with and are
done with a voltmeter unless noted that an oscilloscope or ohmmeter should be used.
