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.
