Introduction
The DGC-2020HD 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-
2020HD operation. A backlit liquid crystal display (LCD) can be viewed under a wide range of ambient
light and temperature conditions. Basler Electric communication software (BESTCOMSPlus®) allows units
to be easily customized for each application. Because of the low sensing burden in the DGC-2020HD,
dedicated potential transformers (PTs) are not required.

An overview of DGC-2020HD Digital Genset Controller functions is provided in the following paragraphs.
Generator and Bus Protection and Metering
Multifunction protection guards against overvoltage, undervoltage, excessive forward and reverse power,
underfrequency, and overfrequency. Overcurrent, phase imbalance, loss of mains, and frequency rate-of-
change protection are available as an option. Each protection function has an adjustable pickup and time
delay setting. Sixteen inverse time curves, in addition to user-programmable curves, enable the DGC-
2020HD to offer overcurrent protection in a variety of applications. Each protective element can be
assigned to the generator, bus 1 or bus 2.
Metered generator and bus 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.
