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 aluminum enclosure
with our fade-, scratch-, and corrosion-resistant Kohlerr
Power Armort automotive-grade textured cashmere
finish. 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 controller is designed to interface with and
control the Kohler Model RXT Automatic Transfer
Switch (ATS).
If the power system uses a different model transfer
switch, the RDC2 controller 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 Controller

RCA and RCAL models are equipped with the RDC2
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.
