Overview

The DGC-2020HD Digital Genset Controller is a rugged, reliable, all-in-one

genset control and load share system. It is designed to be a complete and

adaptive controller that is well suited for mains fail, paralleled units, and

systems with multiple buses. The DGC-2020HD has all of the necessary

features for complete genset control, protection, and metering with an

extensive, but easy-to-use programmable logic system.

Benefits

• Microprocessor-based controller with easy-to-use integrated

programmable logic and load sharing capabilities reduces space

and installation costs while providing increased flexibility and

functionality.

provides exceptional flexibility in all applications.

• Feature-rich design provides exceptional control for advanced

paralleling, load sharing, and protection.

• Capable of monitoring a generator and up to two buses with up

to seven current transformers (CTs), the DGC-2020HD provides

metering and protection for a wide array of applications.

• Built-in real-time monitor for analysis during commissioning and

tuning eliminates the need for external monitoring and decreases

commissioning time and costs.

• Capable of communicating with up to four AEM-2020 Analog

Expansion Modules, four CEM-2020 Contact Expansion Modules,

and one VRM-2020 Voltage Regulation Module, vastly increasing

the I/O capabilities and overall flexibility of the DGC-2020HD and

eliminating the need for external peripheral devices.

• Selectable breaker schemes in BESTlogicPlus make breaker

control with the DGC-2020HD quick and simple.

• Contains an extensive number of communication options which

allow for easy integration into a wide variety of control systems.

• Segmented system capabilities allow for system control and

management, making the DGC-2020HD a fit for any system.

• Tie Breaker Control mode now widens the applications for the

DGC-2020HD, allowing for wider applications such as Main-Tie

Main.

Benefits

• Fundamental sensing technology provides high-end harmonic

protection capabilities that prevent false tripping and allow you to

be more selective with your settings.

• DIN-rail mounting provides easy, time-saving, and compact

installation.

• Simple, economical, yet sophisticated protection for generator,

transformer, distribution, process control, automatic transfer

schemes, and motor applications.

• Many ES relay models are self-powered, eliminating the need for

additional power sources.

• Relay settings are simple and intuitive, making setup fast with no

PC required.

• Red and Green LEDs ensure clear indication of system status to

avoid misinterpretations that could lead to downtime.

• Digital microprocessor design offers consistency for all models,

enhances functionality, and improves performance.

• Internal diagnostics self-monitor and visually annunciate when

relay function or accuracy is compromised, providing clear

understanding of the functional status of the device.

• High dependability and security means relays trip when they are

supposed to and do not trip when they are not supposed to.

Data Logging

The data logging function of the DGC-2020HD records up to six records of user-selectable, real-time

parameter data. For more information, see the Reporting and Alarms chapter in the Operation manual.

Contact Inputs and Outputs

DGC-2020HD controllers have 16 programmable contact inputs. All contact inputs recognize dry

contacts. The programmable inputs can be configured to initiate a pre-alarm or alarm condition. A

programmable input can be programmed to receive a contact input from an automatic transfer switch

(ATS). In addition, a programmable Battle Override function allows overriding of DGC-2020HD 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 twelve programmable 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.

Features

• Four control modes: Automatic Voltage Regulation (AVR), Manual or

Field Current Regulation (FCR), Power Factor (PF) Regulation, and

Reactive Power (Var) Regulation

• Programmable stability settings

• Soft start control with an adjustable time setting in AVR Control

Mode

• Overexcitation limiting (OEL) in AVR, Var, and PF Control Modes

• Underfrequency (Volts/Hertz) compensation or engine unloading

• Overtemperature protection

• Three-phase or single-phase generator voltage (RMS)

sensing in AVR Mode

• Field current and field voltage sensing

• Four contact sensing inputs for system interface

• One common output relay for alarm indication and trip functions

• Six protection functions: overexcitation shutdown, generator

overvoltage shutdown, BE2000E overtemperature shutdown, loss

of generator sensing shutdown, overexcitation limiting, and crowbar

shutdown

• Generator paralleling with reactive droop compensation and reactive

differential compensation

• Front-panel human-machine interface (HMI) indicates system and

BE2000E status and offers the ability to adjust settings at the front

panel.

• Rear RS-232 communication port for personal computer

communication using BESTCOMS™- BE2000E Windows® based

software for fast, user-friendly, setup and control.
