1. Introduction

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 Kohlerr engine. The engine operates on clean-

burning natural gas or LPG. 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 emissions certification.

Digital spark advance optimizes ignition timing for the

selected fuel.

1.3 Alternator

The generator uses Kohler's unique PowerBoostt

voltage regulation system, which provides instant

response to load changes.

PowerBoostt

ensures reliable motor starting and

consistent voltage levels. PowerBoostt

voltage excitation system that employs a winding

independent of the main output windings to provide

excitation voltage.

1.4 Generator Set Enclosure

The generator set is housed in an exclusive engineered

composite enclosure that is corrosion-proof, even in

harsh seaside environments, and impact-resistant,

even in cold weather. The enclosure has a hinged,

locking roof that allows easy access to the generator set

controller when required, but locks securely to prevent

unauthorized access.

To open the roof, insert the key provided with the

enclosure and turn counterclockwise 1/4 turn. Then just

raise the roof. The roof stays open until you are ready to

close it.

Be sure to close and lock the enclosure, and keep the

key in a secure location.

1.5 Transfer Switch

The RDC2 and DC2 controllers are designed to

interface with and control the Kohler Model RXT

Automatic Transfer Switch (ATS). Do not use the Kohler

Model RRT transfer switch with the RDC2 or DC2

controller.

If the power system uses a different model transfer

switch, the RDC2 and DC2 controllers will not control the

transfer switch. An ATS other than the Model RXT must

be equipped with a transfer switch controller and engine

start contacts that connect to the remote engine start

terminals on the generator set.

1.6 Controllers

RESA and RESC models are equipped with the RDC2

controller. RESAL and RESCL models use the DC2

controller. See Figure 1-1.

The controller provides integrated control for the

generator set, Kohlerr Model RXT transfer switch,

programmable interface module (PIM) and load

management devices.

The controller's 2-line LCD screen displays status

messages and system settings that are clear and easy

to read, even in direct sunlight or low light.
