1.0. Introduction
This document details the in-built features, operating procedure requirements of the DGC202X
Series modules. This document is subject to changes without prior notice.
DGC202X series is designed on a common platform and provided variants for different level of
functionality and economics. This allows system designers greater flexibility in the choice of
controller to use for a specific application.
The DGC202X series module has been designed to allow the operator to start and stop the
generator manually or automatically and transfer the load to the generator automatically.
DGC202X automatically starts and stops the generator set depending upon the status of the
mains (utility) supply. The user also has the facility to view the system operating parameters on
LCD display. Additionally, a special mode, Test Mode, is incorporated to facilitate easy debugging
during the building and testing a genset.
The DGC202X module monitors the engine, indicating the operational status. On detection of
faulty conditions, it automatically shutting down the engine. The LCD display indicates the fault
and warning.
The powerful microcontroller contained within the module allows for incorporation of a range of
complex features:
• Icon and Description based LCD display
• True RMS Voltage, Current monitoring
• USB Communications
• Engine parameter monitoring.
• Fully configurable inputs for use as alarms or a range of different functions.
• CAN bus for Engine ECU interface.
• Isolated and Protected RS485 with Modbus.
• Canopy Fan Current Monitoring for Air Cooled Engines.
A robust plastic case designed for front panel mounting houses the module. Connections are via
locking plug and sockets connectors.
All parameters can be changed from the module’s front panel, USB or RS485 communication.
Access to Program/Modify the parameter, through front keys, is protected through a password.

Whenever the generator is required to run, 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 a failed charge situation, the voltage of this terminal is
pulled down to a low voltage. It is this drop in voltage that triggers the charge failure alarm.

R. Start/Stop
If assigned this function to a digital input the input could be used to start/stop
the genset in manual mode.
Connection to ground: Start the Engine
Open: Stop the Engine
Note: Front Start/stop keys shall not work with this assignment.
R. Stop
Remote stop: If assigned this function to a digital input, the Digital input shall,
in manual mode, stop the engine, when connected to ground. This could just
be pulse of around 100ms
R. Start
Remote start: If assigned this function to a digital input, the Digital input shall,
in manual mode, start the engine, when connected to ground. This could just
be pulse of around 100ms
Auto/Manual
If assigned this function to a digital input, the input will select the mode of
operation.
Connection to Ground: Auto Mode
Open: Manual Mode
The front key can’t be used to select Auto or Manual mode but the test mode
can still be selected form front.

Note: There are some restriction on the assignment of the function to the Digital Inputs
a)R . Start/Stop can not be selected along with either of R.Stop or R.start
b)R .Start and R.Stop both must be assigned. Assigning only one is not allowed.
6.0. Modes of Operation
Mode
Description
Auto
The genset runs without any human interventions.
The engine shall be switched on when the Mains becomes unhealthy as per the user
defined settings.
The mains can be monitored for voltage levels, frequency, phase sequence and
voltage unbalance. The monitoring of frequency, phase sequence and voltage
unbalance can be disabled.
Once the Mains voltage is outside the limit, continuously for the programmed time,
the engine is cranked and load transferred to the genset after warmup time. The
engine keeps running till the Mains is restored and upon its restoration, the load is
transferred to the Mains and engine is shut down after cooling. This cycle keeps
repeating.
On detection of unhealthy conditions(faults) the engine shall be shut down and an
alarm (Hooter) is activated for the programmed time.
Manual
In this mode the starting and stopping of the genset is controlled manually. All other
functions like load transfer and protections are performed automatically
Starting the Engine: Depending upon the setting of the digital Input the engine could
be started by either:
• Front Start Key
• R. Start Key
• R. Start/Stop Key
Stopping Engine: The engine can be shut down either automatically on restoration
of Mains Voltage (Auto shut down) if the setting xxxxxxxxx is enabled in xxxxxx
Parameter else it’s shuts down by user depending upon the digital Input setting
• Front Stop Key
• R. Stop Key
• R. Start/Stop Key
Test
This is special mode meant for testing during building the system or trouble
shooting.
This mode allows the operator to manually start and stop the engine also the mains
contactor and generator contacts can be manually controlled from Front Keys
7.0. Analog Sensors in Details
