DECISION MAKER 3+, 16-LIGHT GENERATOR CONTROLLER
Markets: Industrial, Marine, Mobile, Residential
The DEC 3+ controller firmware (application program) is factory loaded and used for field upgrades or replacement.
Program Loader software is required to field upgrade the controller firmware.
Controller board GM28725 (red board) is required to upgrade DEC 3+ controllers produced before November, 2003.
Board GM64497 (blue board) incorporates a larger processor and supports new GM, Doosan, and Scania engines. The blue board uses application version 2.00 or higher.
Communication module (GM32644-KP1) is required to provide Modbus communications for the DEC 3+.
XC200 is a DEC 3+ that has been brand labelled for OEM sales and is not available in North America.

Low Coolant Level: Added support for RSA1000
MDEC Communication: Modified engine identification via J1939
Overspeed Shutdown: Correction to 50HZ DIP switch default to avoid nusance shutdown.
Engineered Special
Cooldown Temperature Override Selection: The generator set will continue to run during a five-minute cooldown cycle, or shutdown immediately, as selected via a DIPswitch.
