1. Introduction
1.1 About SGC 120/121
This document presents information necessary for operating DEIF's SGC 120/121 genset controllers.
SGC 120/121 are modern genset controllers with user friendly HMI and full graphics LCD. The controllers come with a highly
versatile software. Extensive inputs and outputs support a wide variety of industry standard features in diesel/gasoline genset
applications.
SGC 121 includes electronic governing for engines with mechanical fuel systems. With a rotary actuator as add-on for air/fuel
charge control, SGC 121 can perform electronic governing of the engine within ISO 8528 class G3 limits.
The DEIF Smart Connect software offers flexibility to configure each individual input and output for a specific function or application.
All parameters can also be configured on the genset controller.
