9400200990 Rev I DGC-2020 General Information 1-1
SECTION 1 •GENERAL INFORMATION
DESCRIPTION
The DGC-2020 Digital Genset Controller provides integrated engine-genset control, protection, and
metering in a single package. Microprocessor based technology allows for exact measurement, setpoint
adjustment, and timing functions. Front panel controls and indicators enable quick and simple DGC-2020
operation. Basler Electric communication software (BESTCOMSPlus) allows units to be easily customized
for each application. Because of the low sensing burden in the DGC-2020, dedicated potential
transformers (PTs) are not required. A wide temperature-range liquid crystal display (LCD) with
backlighting can be viewed under a wide range of ambient light and temperature conditions.
FEATURES
DGC-2020 Digital Genset Controllers have the following features:
•Local and Remote Generator Control
•Engine and Generator Protection
•Programmable Analog Engine Senders
•ECU Communications via SAE J1939
•16 Programmable Contact Inputs
•Programmable Logic
•Automatic Transfer Switch Control (Mains Failure)
•Integrated RS485
•Auto Synchronizing
•Exercise Timer
•Additional modules available to expand the capabilities of the DGC-2020
FUNCTIONS
DGC-2020 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, and overfrequency. Overcurrent and phase imbalance protection is
available as an option. Each generator protection function has an adjustable pickup and time delay
setting. Sixteen inverse time curves enable the DGC-2020 to offer overcurrent protection in a variety of
applications.
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 reporting.
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 Section 3, Functional Description, Event Recording.
Auto-Synchronizer
An optional automatic synchronizer monitors the bus and generator voltages and supplies discrete
raise/lower correction signals to synchronize the generator voltage, frequency, and slip angle with that of
the bus.

1-2 DGC-2020 General Information 9400200990 Rev I
Contact Inputs and Output Contacts
DGC-2020 controllers have one, dedicated emergency stop contact input and 16 programmable contact
inputs. All contact inputs recognize dry contacts. The programmable inputs can be configured to initiate a
pre-alarm or alarm. A programmable input can be programmed to receive an input from an automatic
transfer switch or override DGC-2020 alarms and protection functions. Each programmable input can be
assigned a user-defined name for easy identification at the front panel display and in fault records.
Output contacts include three dedicated relays for energizing an engine’s glow plugs, fuel solenoid, and
starter solenoid. An additional four user-programmable output contacts are provided if the style number is
xxAxxxxxx. If the style number is xxBxxxxxx, an additional twelve output contacts are provided.
Additional contact inputs and output contacts can be accommodated with an optional CEM-2020 (Contact
Expansion Module). Contact Basler Electric for ordering information.
Automatic Transfer Switch Control (Mains Failure)
The DGC-2020 has the ability to detect a mains failure via a single-phase Bus input. A mains failure is
established when any one of the following conditions are met:
•Bus voltage falls below dead bus threshold
•Bus voltage unstable due to overvoltage or undervoltage
•Bus voltage unstable due to overfrequency or underfrequency
At this time, the DGC-2020 will start the genset and when ready, apply power to the load via the genset.
The DGC-2020 implements open transitions to and from the mains. When the mains returns and is
considered stable, the DGC-2020 will transfer the load back to the mains.
Communication
Standard DGC-2020 communication features include a standard USB port and SAE J1939 interface.
Optional communication features include a dial-out modem and RS-485 communication port.
BESTCOMSPlus can communicate with the DGC-2020 through ethernet via an optional LSM-2020 (Load
Share Module). Contact Basler Electric for ordering information.
USB Port
A USB communication port can be used with BESTCOMSPlus software to quickly configure a DGC-2020
with the desired settings or retrieve metering values and event log records.
CANBus Interface
A CANBus interface provides high-speed communication between the DGC-2020 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 CANBus 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-2020 and may be obtained using
BESTCOMSPlus software.
•MTU/MDEC Protocol - A DGC-2020 connected to a genset equipped with an MTU MDEC receives
Oil pressure, coolant temperature, and engine speed data from the engine controller, along with
various alarms and pre-alarms that are MDEC specific. In addition, the DGC-2020 tracks and displays
the active fault codes issued by the MDEC ECU.
Dial-Out Modem
The optional dial-out modem enables remote control, monitoring, and setting of the DGC-2020. When an
alarm or pre-alarm condition occurs, the DGC-2020 can dial up to four telephone numbers, in sequence,
until an answer is received and the condition is annunciated.
RS-485 Port
An optional RS-485 communication port uses the Modbus communication protocol and enables remote
control and monitoring of the DGC-2020 over a polled network.

9400200990 Rev I DGC-2020 General Information 1-3
LSM-2020 (LOAD SHARE MODULE)
The optional LSM-2020 in conjunction with the DGC-2020 provides load sharing between governors
through an analog load share line. The LSM-2020 communicates through an ethernet port and provides
access to the DGC-2020 via ethernet. Refer to Section 8, LSM-2020 (Load Share Module), for more
information.
CEM-2020 (CONTACT EXPANSION MODULE)
The optional CEM-2020 provides 10 additional contact inputs and 24 additional output contacts to the
DGC-2020. The CEM-2020 communicates with the DGC-2020 through a CANBus interface. Refer to
Section 9, CEM-2020 (Contact Expansion Module), for more information.
STYLE AND PART NUMBERS
Style Number
Standard-order DGC-2020 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

NOTES
1.) If the DGC-2020 is providing one end of the J1939 backbone, a 120 Ω
terminating resistor should be installed across terminals 48 (CANL) and 49
(CANH).
2.) If the DGC-2020 is not part of the J1939 backbone, the stub connecting the
DGC-2020 to the backbone should not exceed 914 mm (3 ft) in length.
3.) The J1939 drain (shield) should be grounded at one point only. If grounded
elsewhere, do not connect the drain to the DGC-2020.
CAUTION
Replacement of the backup battery for the real-time clock should be performed
only by qualified personnel.
Do not short-circuit the battery, reverse battery polarity, or attempt to recharge
the battery. Observe polarity markings on the battery socket while inserting a
new battery. The battery polarity must be correct in order to provide backup for
the real-time clock.
It is recommended that the battery be removed if the DGC-2020 is to be operated
in a salt-fog environment. Salt-fog is known to be conductive and may short-
circuit the battery.
NOTE
Failure to replace the battery with Basler Electric P/N 38526 may void the
warranty.

Dielectric Strength: IEC 255-5
Impulse: EN60664-1
Transients: EN61000-4-4
Static Discharge: EN61000-4-2
Shock
15 G in 3 perpendicular planes
Vibration
Swept over the following ranges for 12 sweeps in each of three mutually perpendicular planes with each
15-minute sweep consisting of the following:
5 to 29 to 5 Hz: 1.5 G peak for 5 min.
29 to 52 to 29 Hz: 0.036” DA for 2.5 min.
52 to 500 to 52 Hz: 5 G peak for 7.5 min.
Radio Interference
Type tested using a 5 W, hand-held transceiver operating at random frequencies centered around 144
and 440 MHz with the antenna located within 150 mm (6”) of the device in both vertical and horizontal
planes.
HALT (Highly Accelerated Life Testing)
HALT is used by many manufacturers to prove that their products will provide the user with many years of
reliable service. HALT subjects the device to extremes in temperature, shock, and vibration to simulate
years of operation, but in a much shorter period span. HALT allows Basler Electric to evaluate all possible
design elements that will add to the life of this device. As an example of some of the extreme testing
conditions, the DGC-2020 was subjected to temperature tests (tested over a temperature range of -100°C
to +115°C), vibration tests (of 5 to 50 G at +20°C), and temperature/vibration tests (tested at 40 G over a
temperature range of -80°C to +90°C). Combined temperature and vibration testing at these extremes
proves that the DGC-2020 is expected to provide long-term operation in a rugged environment. Note that
the vibration and temperature extremes listed in this paragraph are specific to HALT and do not reflect
recommended operation levels. These operational ratings are included in Section 1 of this manual.
