4.Features
| FEATURES | ||||||||
| DVR2000E units have the following features andcapabilities. | ||||||||
| • Four control modes: automatic voltage regulation (AVR), manualor 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 AVRcontrol mode. | ||||||||
| • Overexcitation (OEL) limiting in AVR, VAR, and PF controlmodes. | ||||||||
| • Underfrequency (volts/hertz) regulation. | ||||||||
| • Crowbar circuitry protects the field. | ||||||||
| • Overtemperature protection. | ||||||||
| • Three-phase or single-phase generator voltage (RMS)sensing/regulation in AVR mode. | ||||||||
| • Single-phase generator current sensing for metering andregulation purposes. | ||||||||
| • Field current and field voltage sensing. | ||||||||
| • Four contact sensing inputs for system interface. | ||||||||
| • One common output relay for alarm indication and tripfunctions. | ||||||||
| • Six protection functions (overexcitation shutdown, generatorovervoltage shutdown, DVR | ||||||||
| overtemperature shutdown, | ||||||||
| loss of generator sensing shutdown, overexcitation limiting andcrowbar shutdown). | ||||||||
| • Generator paralleling with reactive droop compensation andreactive differential compensation. | ||||||||
| • Front-panel human-machine interface (HMI) indicates system andDVR2000E status and gives | ||||||||
| the ability to make setting changes at the front panel. | ||||||||
| • Rear RS-232 communication port for personal computercommunication using MARATHON- | ||||||||
| DVR2000E- COMS | ||||||||
| Windows based software for fast, user-friendly, setup and control. |
