Introduction
This manual contains operation and maintenance information for a diesel engine-generator manufactured by
ITW GSE, Palmetto, Florida 34221
This manual, including all information contained therein, is exclusive and confidential property of ITW
GSE. This manual is not to be copied, reproduced, or delivered or disclosed to others, in whole or in
part, except with express written permission of ITW GSE.
This manual is not intended to be a textbook on electricity or electronics. Its primary purpose is to provide
information and instructions to experienced operators, electricians, and mechanics that have never operated
this equipment. It is the intent of this manual to guide and assist operators and maintenance personnel in the
proper use and care of the equipment.
Use of the manual should not be put off until trouble or a need for help develops. Read the instructions before
starting the unit. Learn to use the manual and to locate information contained in it. Its style and arrangement
are very similar to commercial aircraft manuals.
The manual is divided into five chapters plus appendices. Each chapter is divided into as many sections as
required. Each new section starts with page 1. Each page is identified by chapter, section and page number,
which are located in the lower, outside corner.
When information located in another portion of the manual is referred to, a chapter, section, and paragraph or
figure number identify its location. For example: “(see Section 2-3, Paragraph 1.a.)” refers to information
located in Chapter 2, Section 3, Paragraph 1.a. If a chapter and section are not indicated in a reference, the
referenced material is located in the same section as the reference, for example: “(see Paragraph 1.a.).”
In addition to operation and maintenance instructions, the manual contains an illustrated parts list in Chapter
4 and a collection of manufacturer’s literature and supplemental information in Chapter 5.
Contents of the manual are arranged as follows:

Safety Warnings and
Cautions.
WARNING
ELECTRIC SHOCK can KILL. Do not touch live electrical parts.
ELECTRIC ARC FLASH can injure eyes, burn skin, cause equipment damage, and
ignite combustible material. DO NOT use power cables to break load. Prevent tools
from causing short circuits.
IMPROPER PHASE CONNECTION, PARALLELING, OR USE can damage this and
attached equipment.
IMPORTANT
Protect all operating personnel. Read, understand, and follow all instructions in the
Operating/Instruction Manual before installing, operating, or servicing the equipment.
Keep the manual available for future use by all operators.
WARNING
CALIFORNIA PROPOSITION 65 - DIESEL ENGINES. Diesel engine exhaust and
some of its constituents are known to cause cancer, birth defects and other illnesses.
1) General
Equipment that supplies electrical power can cause serious injury or death, damage to other equipment or
property. The operator must strictly observe all safety rules and take precautionary actions. Safe practices
have been developed from past experience in the use of power source equipment. While certain practices
below apply only to electrically powered equipment, other practices apply to engine-driven equipment, and
some practices to both.
2) Shock Prevention
Bare conductors, terminals in the output circuit, or ungrounded, electrically live equipment can fatally shock a
person. Have a certified electrician verify that the equipment is adequately grounded and learn what
terminals and parts are electrically HOT. Avoid hot spots on machine. Use proper safety clothing,
procedures and test equipment.
The electrical resistance of the body is decreased when wet, permitting dangerous currents to flow through it.
When inspecting or servicing the equipment, do not work in damp areas. Stand on a dry rubber mat or dry
wood, and use insulating gloves when dampness or sweat cannot be avoided. Keep clothing dry, and never
work alone.
a) Output Cables and Terminals
Inspect cables frequently for damage to the insulation and the connectors. Replace or repair cracked
or worn cables immediately. Do not overload cables. Do not touch output terminal while equipment
is energized.

Safety Warnings
Page 2
3) Service and Maintenance
This equipment must be maintained in good electrical condition to avoid hazards stemming from
disrepair. Report any equipment defect or safety hazard to the supervisor and discontinue use of the
equipment until its safety has been assured. Repairs should be made by qualified personnel only.
Before inspecting or servicing this equipment, take the following precautions:
a) Shut off all power at the battery disconnect before inspecting or servicing the equipment.
b) Lockout the equipment at the battery disconnect switch if it is out of service.
c) If troubleshooting must be done with the unit energized, have another person present who is trained
in turning off the equipment and providing or calling for first aid.
4) Fire and Explosion Prevention.
Fire and explosion are caused by electrical short circuits, combustible material near engine exhaust pipes,
misuse of batteries and fuel, or unsafe operating or fueling conditions.
a) Electrical Short Circuits and Overloads.
Overloaded or shorted equipment can become hot enough to cause fires by self-destruction or by
causing nearby combustibles to ignite.
b) Batteries.
Batteries may explode and/or give off flammable hydrogen gas. Acid and arcing from a ruptured
battery can cause fires and additional failures. When servicing, do not smoke, cause sparking, or use
open flame near the battery.
c) Engine Fuel.
Use only approved fuel container or fueling system. Fires and explosions can occur if the fuel tank is
not grounded prior to or during fuel transfer. Shut unit DOWN before opening fuel tank cap. DO NOT
completely fill tank, because heat from the equipment may cause fuel expansion overflow. Remove
all spilled fuel IMMEDIATELY, including any that penetrates the unit. After clean-up, open equipment
doors and blow fumes away with compressed air.
5) Toxic Fume Prevention.
Carbon monoxide - Engine exhaust fumes can kill and cause health problems. Pipe or vent the exhaust
fumes to a suitable exhaust duct or outdoors. Never locate engine exhausts near intake ducts of air
conditioners.
6) Bodily Injury Prevention.
Serious injury can result from contact with fans or hot spots inside some equipment. Shut DOWN such
equipment for inspection and routine maintenance. When equipment is in operation, use extreme care in
doing necessary troubleshooting and adjustment. Do not remove guards while equipment is operating.

7) Medical and First Aid Treatment.
First aid facilities and a qualified first aid person should be available for each shift for immediate treatment
of all injury victims. Electric shock victims should be checked by a physician and taken to a hospital
immediately if any abnormal signs are observed.
EMERGENCY
FIRST AID
. SEEK ADDITIONAL ASSISTANCE. Use First Aid techniques recommended by
American Red Cross until medical help arrives.
IF BREATHING IS DIFFICULT, give oxygen, if available, and have victim lie down.
FOR ELECTRICAL SHOCK, turn off power. Remove victim; if not breathing, begin
artificial respiration, preferably mouth-to-mouth. If no detectable pulse, begin external
heart massage.
8) Equipment Precautionary Labels
Inspect all precautionary labels on the equipment monthly. Order and replace all labels that cannot be
easily read.

Description/Operation
1) General
The basic generator sets covered in this manual, manufactured by ITW GSE Group, are rated at 60kVA
and 90kVA they are designed to produce and deliver 115/200-volt, 400 Hz, 3-phase AC power to a
parked aircraft or other load. Some generator models with the Active Rectified Unit (ARU) option also
provide 28.5 volts DC for aircraft having those requirements. A comprehensive review of the 28VDC
output Active Rectifier Unit (ARU) is located in Appendix A.
This version of the manual reflects firmware changes to the operating system through version F. (The
firmware version of the unit is found on the unit information screen in the View Parameters Menu. Section
4.0.1). These changes include new setup menu items and changing the order of several screens.

For purpose of orientation when designating RIGHT and LEFT throughout this manual, the radiator is
considered to be at the FRONT of the unit and the generator is at the REAR. RIGHT and LEFT are
determined by standing at the REAR facing the machine. As an example, the control panel is mounted
on the RIGHT FRONT side of the unit.
