Kohler 12RES, 8.5RES manual Features, Specifications, Generator, Engine, Advanced Digital Control

Section 1 Features

1.1 Specifications

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 Generator

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 utilizes a voltage excitation system that employs a winding independent of the main output windings to provide excitation voltage.

1.3 Engine

The generator set has a four-cycle, twin cylinder, air- cooled Kohlerr engine. The engine operates on clean-burning natural gas or propane (LP) vapor. Engine features include:

DEfficient overhead valve design and full pressure lubrication for maximum power, torque, and reliability under all operating conditions.

DDependable, maintenance-free electronic ignition.

DPrecision-formulated cast iron construction of parts subjected to the most wear and tear.

DField-convertible multi-fuel systems that allow fuel changeover from natural gas to LP vapor (and vice-versa) while maintaining CARB emission certification.

DDigital spark-advance module (DSAM) optimizes ignition timing for the selected fuel (12RES).

1.4 Advanced Digital Control

The generator set is equipped with the Kohlerr Advanced Digital Control (ADC 2100). Controller features include the following:

DCompact controller
