Introduction
SEDEMAC GC1200 is a series of modern and feature rich genset controllers with user-friendly HMI and full
graphics LCD. The GC1200 controllers come bundled with highly versatile software & extensive I/O's, and
thereby support a wide variety of industry standard features in diesel / gas / gasoline engine gensets. They also
offer unique features such as electronic governing for engines with mechanical fuel systems. With a SEDEMAC
rotary actuator as an add-on for air/fuel charge control, the GC1200 controllers can subsume the electronic
governing duty for the engine and offer tight speed governing performance within ISO 8528:G3 class limits.
This document gives operating instructions for SEDEMAC's GC1200 series genset controllers (refered to as
GC12xx further in the document). Refer to the Software Manual for Configuration Utility For GC1200 series
Genset Controllers for details of the configuration utility.

The charge fail input is a combined input and output terminal. When the genset starts, the terminal provides
excitation current to the charge alternator field winding. When the charge alternator is correctly charging the battery,
the voltage of the terminal is close to the battery supply voltage. In case of failure of charging alternator, the voltage
of this terminal is pulled down to a low voltage. This drop in voltage triggers the charge failure alarm. The level at
which this operates and whether this triggers a warning or shutdown alarm is configurable.

The actuator outputs are used only for the SEDEMAC actuator, if installed. The SEDEMAC actuator is a 4-wire
actuator that is used for creating an electronic governing application in case of a mechanical fuel system engine. In
diesel engines, the rotary actuator's shaft output gets mechanically connected to the stop lever or the throttle lever
of an inline or rotary fuel injection pump. In case of petrol or natural gas engines, the rotary actuator's shaft output
gets connected to the throttle / charge control valve.
