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
D
lubrication for maximum power, torque, and reliability
under all operating conditions.
Dependable, maintenance-free electronic ignition.
D
Precision-formulated cast iron construction of parts
D
subjected to the most wear and tear.
Field-convertible multi-fuel systems that allow fuel
D
changeover from natural gas to LPG (and vice- versa)
while maintaining emissions certification.
Digital spark advance optimizes ignition timing for the
D
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.
