Section 1 Descriptions and Service Views
1.1 Introduction
The generator set specification sheets provide specific
generator and engine information. Refer to the spec
sheet for data not supplied in this manual. Consult the
generator set service manual, engine operation
manual, and engine service manual for additional
specifications. Obtain copies of the latest spec sheets,
manuals, diagrams, and drawings from your local
distributor/dealer.
1.2 Engine
The generator set has a four-cycle, twin cylinder,
air-cooled Kohler engine. The engine operates on
cleanburning natural gas or LPG fuel. Engine
features include:
• Efficient overhead valve design and full pressure
lubrication for maximum power, torque, and
reliability under all operating conditions.
• Dependable, maintenance-free electronic ignition.
• Precision-formulated cast iron construction of parts
subjected to the most wear and tear.
• Field-convertible multi-fuel systems that allow fuel
changeover from natural gas to LPG (and vice
versa) while maintaining CARB emission
certification.
• The variable-speed engine runs at 2300 rpm at no
load and 2900 rpm when supplying full load.
1.3 Generator Set Enclosure
The generator set is housed in a steel enclosure with
Power Armor powder coat paint. The enclosure has a
hinged, locking door that allows easy access to the
generator set controller when required, but locks
securely to prevent unauthorized access.
To open the door, insert the tool provided with the
enclosure and turn counterclockwise 1/2 turn.
Be sure to close and lock the enclosure, and keep the
tool in a secure location.
1.4 Alternator
The 6VSG is a direct current (DC) output machine. It
utilizes a 24-pole permanent magnet construction to
create high frequency three-phase alternating current
which is rectified to produce low-ripple DC output.
1.5 Controller
The Model 6VSG generator set comes equipped with
the VSC controller. See Figure 1-1. The controller
provides integrated control for the generator set and
the optional programmable interface module (PIM) or
optional communications kit interface board.
The controller’s two-line LCD screen displays status
messages and system settings that are clear and easy
to read in all lighting conditions, including direct
sunlight and low light.
