FUNCTIONS
Event Recording
The DGC-2020 has an event recorder that provides a record of alarms, pre-alarms, engine starts, engine runtime
loaded, engine runtime unloaded, last run date, and many other events that are all date and time stamped to help the
user determine the cause and effect of issues related to the generator set. Contains 30 event records each retaining
up to 99 occurrences in memory. Time, date and engine hour detail is available for the most current 30 occurrences
within each event record.
Transfer Switch Control (Mains Failure) - Level 3 only
The DGC-2020 monitors utility (mains) and determines if it is providing voltage that is suitable for the loads. If the
utility (mains) goes beyond predetermined levels, the generator is started and the utility (mains) is disconnected from
the load and the generator is connected. When the utility (mains) returns to acceptable levels for a sufficient time, the
generator is disconnected and the utility (mains) is reconnected to the load. It also includes appropriate adjustable
timers or time delays for establishing stable utility (mains) operation. Utility breakers must be electronically operated.
RS-485 Communications
When utilized, the user can send and receive information from the DGC-2020 via the RS-485 communications port
and Modbus-RTU protocol. This feature allows the DGC-2020 controlled genset to be fully integrated into the building
management system. Please see the Instruction Manual for the Modbus register list.
Programmable Logic
The DGC-2020 offers a very powerful, yet easy to use, programmable logic scheme for custom programming of the
various inputs, outputs, alarms, and pre-alarms. It allows these elements to be integrated into a complete logic
scheme so that the user can meet even the most complex specification. The Programmable Logic control includes
the selection of logic gates and timers with drag-and-drop technology to make it fast and simple.
Remote Display Panel Annunciation
The DGC-2020 can communicate to a remote display panel, Model RDP-110. This requires only two wires to
annunciate all of the alarms and pre-alarms required by NFPA-110 Level I and II. External power is required.
Modem - Level 2 and 3 only
A 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.
J1939 Communications
J1939 CANBUS communications allows the DGC-2020 to communicate to the engine's ECU (Engine Control Unit) to
gather critical engine information like oil pressure, engine coolant temperature, RPM, battery voltage, and many
more. By utilizing the ECU, adding analog engine senders is no longer required. This can save substantial money for
the installer. It also eliminates any errors or discrepancies between the ECU data and the data displayed on the
DGC-2020 that may be present due to analog sender inaccuracies or incompatibility. A total of 47 engine parameters
can be obtained via the ECU. You also can derive the added benefit of having access to the ECU's diagnostic
troubleshooting codes, or DTCs. The DTCs provide information about the engine's operating conditions and
communicates these via J1939, to the DGC, thus eliminating the need for hand-held service tools to diagnose simple
engine issues. With the optional modem, the DTCs can be accessed remotely, and valuable service time can be
saved by remote diagnostics and taking the right parts to fix the problem the first time.

DGC-2020
ADDITIONAL SPECIFICATIONS
The DGC-2020 has been designed to provide maximum functionality at a minimum price. You only buy what you
need. Below are options selected to help maximize the value provided by the DGC-2020.
Battery Backup for Real Time Clock - All Levels
A ten-year (typical life) lithium battery is used to
provide long-term maintenance of the real time clock
setting. This battery is serviceable by removing the
rear cover. The settings, programming, and event
records are saved in nonvolatile memory and do not
require battery backup.
Internal Dial-In / Dial-Out Modem - Levels 2 and 3
The DGC-2020 can provide long distance
communications by including an internal modem.
There are two modems available, one for U.S. and one
for European telephone systems. When a
modem is selected, the user can access the DGC2020 from virtually anywhere via a telephone line. The
user can control and monitor the genset as if standing
right next to it. The DGC-2020 can also dial out for
pre-programmed circumstances to alert the user of
selected conditions.
Additional Generator Protection - Levels 2 and 3
In addition to the standard generator protection (27,
32, 40Q, 59, 81O, 81U), the DGC-2020 also can be
equipped with a more sophisticated generator
protection system. This option provides an overcurrent
element (51) with 17 selectable time current
characteristic curves and a voltage phase balance
protection function (47).
Auto-Synchronizer - Level 3 only
When the DGC-2020 is configured with this option, the
user can select between 2 types of autosynchronizers,
phase lock or anticipatory style. In both methods, the
DGC-2020 adjusts generator frequency and voltage to
match that of the bus (mains) via contact outputs, then
connects the generator to the bus by closing the
connecting breaker. When the control mode is set to
Power Factor (PF) or kVar, the setpoint can be derived
either from a user setting or from an analog input.
Multigen Management - Level 3 only
Enabling sequencing on a networked group of load
share units allows these units to manage load by
starting and stopping appropriate units based on a
factor of load demand and available capacity. The
mode of operation is used to determine the order in
which each generator in a group will contribute to the
systems power production upon a demand start/stop
request.
Modes of operation include:
 Staggered service time
 Balanced service time
 Largest size first
 Smallest size first
 Smallest unit ID
Breaker Management - Level 3 only
The DGC-2020 is capable of controlling the generator
breaker and the mains breaker. The status of the
breakers is determined by using BESTLogicPlus
Programmable Logic to setup the GENBRK and
MAINSBRK logic blocks. These logic blocks have
outputs that can be configured to energize an output
contact and control a breaker as well as inputs for
breaker control and status. The DGC-2020 will
attempt to close a breaker only after verifying that it
can be closed. If the breaker cannot be closed, the
close request will be ignored. Only one breaker can be
closed at a time. Synchronization is required before
closing the breaker to a live bus. Closure to a dead
bus can be performed after meeting dead bus
threshold and timing requirements set by the user.

OPTIONAL ACCESSORIES
Load Share Module 2020 (LSM-2020) with Ethernet Capability
The LSM-2020 is an easy to connect and use add-on module that allows the DGC-2020 to control VAR/PF and kW
load sharing of a paralleled generator set. The LSM-2020 is remotely mounted and communicates to the
DGC-2020 via J1939 CANbus communications. With the Level 3 controller, this module provides the flexibility to
use the same model DGC-2020 gen-set controller for single unit (standalone power) applications and parallel
gen-set applications. Pure flexibility is one of the benefits of the DGC-2020, and this add-on module enhances
that.

Analog Input (Configurable): The LSM-2020 provides one analog input that is user-selectable for 4 to 20 mA
or 0 to 10 Vdc. This input can be used to control the power factor (PF) or kVar setpoint when paralleled to the
utility.

Analog Outputs: The LSM-2020 has (3) analog outputs—one connected to the voltage regulator and one to
the speed governor. There is also one output connected to the load sharing lines. All of these outputs can be
selected via BESTCOMSPlus for 4-20 mA or ±10 Vdc. The analog outputs also can be scaled to adapt to the
compatibility requirements of existing analog equipment.

Multiple Generator Management: This module adds demand start/stop control and generator sequencing to
the feature packed DGC-2020. The generator sequencing can be selected by priority number, generator size,
service hours remaining, and balanced service hours. This sequencing function is even smart enough to
determine if all the connected controllers are in the same mode.

