Introduction
The DGC-2020ES Digital Genset Controller provides integrated engine-genset control, protection, and
metering in a rugged and economical package. Its features set make the DGC-2020ES ideal for
standalone genset applications where paralleling or load sharing is not required. Microprocessor based
technology allows for exact measurement, setpoint adjustment, and timing functions. Front panel controls
and indicators enable quick and simple DGC-2020ES operation. Basler Electric communication software
(BESTCOMSPlus
burden in the DGC-2020ES, dedicated potential transformers (PTs) are not required. A liquid crystal
display (LCD) with backlighting can be viewed under a wide range of ambient light and temperature
conditions.
Features and Functions
The DGC-2020ES Digital Genset Controller has the following features:
• Generator Control
• Engine and Generator Pr ot ect ion
• Automatic Transfer Switch Control (Mains Failure)
• Automatic Generator Configuration Detection
• Programmable Analog Engine Senders
• Seven Programmable Contact Inputs
• Programmable Logic
• Exercise Timer
• ECU Communications via SAE J1939
• Additional contact input/output module available to expand the capabilities of the DGC-2020ES
®
) allows units to be easily customized for each application. Because of the low sensing
DGC-2020ES Digital Genset Controllers perform the following functions:
Generator Protection and Metering
Multifunction generator protection guards against generator overvoltage, undervoltage, reverse power,
loss of excitation, underfrequency, overfrequency, and overcurrent. Each generator protection function
has an adjustable pickup and time delay setting.
Metered generator parameters include voltage, current, real power (watts), apparent power (VA), and
power factor (PF).
Engine Protection and Metering
Engine protection features include oil pressure and coolant temperature monitoring, overcrank protection,
ECU specific protection elements, and diagnostic rep o rt ing.
Metered engine parameters include oil pressure, coolant temperature, battery voltage, speed, fuel level,
engine load, coolant level (from ECU), ECU specific parameters, and run-time statistics.
Event Recording
An event log retains a history of system events in nonvolatile memory. Up to 30 event types are retained
and each record contains a time stamp of the first and last occurrence, and the number of occurrences for
each event. For more information, see the Event Recording chapter.
Contact Inputs and Outputs
DGC-2020ES controllers have seven programmable contact inputs. All contact inputs recognize dry
contacts. The programmable inputs can be configured to initiate a pre-alarm or alarm. An input can be
programmed to receive an input from an automatic transfer switch. Inputs can also be programmed to
override DGC-2020ES alarms and protection functions. Each input can be assigned a user-defined name
for easy identification at the front panel display and in fault records.
DGC-2020ES Introduction
2 9469200990 Rev C
Output contacts include three dedicated relays for energizing an engine’s glow plugs, fuel solenoid, and
starter solenoid. Four additional user-programmable output contacts are provided.
Additional contact inputs and output contact requirements can be accommodated with an optional CEM2020 (Contact Expansion Module). Contact Basler Electric for ordering information.
Automatic Transfer Switch Control (Mains Failure)
The DGC-2020ES can detect a mains failure via a single- or three-phase bus input. A mains failure is
established when any one of the following conditions are met:
• Any phase of bus voltage falls below dead the bus threshold
• Any phase of bus voltage is unstable due to overvoltage or undervoltage
• Any phase of bus voltage is unstable due to overfrequency or underfrequency
At this time, the DGC-2020ES will start the genset and when ready, apply power to the load via the
genset. The DGC-2020ES implements open transitions to and from the mains. When the mains returns
and is considered stable, the DGC-2020ES will transfer the load back to the mains.
Communication
DGC-2020ES communication features include a standard USB port for local (and temporary)
communication, SAE J1939 interface for remote communication, and RS-485 interface for communication
with an optional Remote Display Panel.
USB Port
The USB communication port can be used with BESTCOMSPlus software to quickly configure a DGC2020ES with the desired settings or retrieve metering values and event log records.
CAN Interface
The CAN interface provides high-speed communication between the DGC-2020ES and the engine control
unit (ECU) on an electronically controlled engine. This interface provides access to oil pressure, coolant
temperature, and engine speed data by reading these parameters directly from the ECU. When available,
engine diagnostic data can also be accessed. The CAN interface supports the following protocols:
• SAE J1939 Protocol - Oil pressure, coolant temperature, and engine speed data are received
from the ECU. In addition, DTCs (Diagnostic Trouble Codes) help diagnose any engine or related
failures. The engine DTCs are displayed on the front panel of the DGC-2020ES and may be
obtained using BESTCOMSPlus® software.
• MTU Protocol - A DGC-2020ES connected to a genset equipped with an MTU ECU receives oil
pressure, coolant temperature, and engine speed data from the engine controller, along with
various alarms and pre-alarms that are MTU specific. In addition, the DGC-2020ES tracks and
displays the active fault codes issued by the MTU engine ECU.
Style Number
Standard-order DGC-2020ES controllers are identified by a style number which consists of a combination
of letters and numbers that define the controller’s electrical characteristics and operational features. The
model number, together with the style number, describes the options included in a specific controller.
Figure 1 illustrates the DGC-2020ES style number identification chart.

2 Mains Failure Detection
Optional Features and Capa bilities
CEM-2020 (Contact Expansion Module)
The optional CEM-2020 provides 10 additional contact inputs and 18 or 24 additional output contacts
(depending on module type) to the DGC-2020ES. The CEM-2020 communic a tes with the DGC-2020ES
through a CAN interface. Refer to the CEM-2020 chapter for more information.
Remote Display Panel
The optional Remote Display Panel provides remote indication of many pre-alarm and alarm conditions.
The DGC-2020ES communicates with the Remote Display Panel through an RS-485 interface. Refer to
the Controls and Indicators chapter for more information.
