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.
