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
® ) allows units to be easily customized for each application. Because of the low sensing
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.

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 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 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.
