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
FUNCTIONS
DGC-2020 Digital Genset Controllers perform the following functions:
Generator Protection and Metering
Multifunction generator protection guards against generator overvoltage, undervoltage, 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.
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.
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
