2000E presents an electric shock risk. Terminals and heat sinks are live at potentially
lethal voltages. This high voltage may cause electrical shock that could result in injury or death.
To avoid personal injury or equipment damage, only qualifi ed personnel should perform the
procedures presented in this manual.
Meggers and high potential test equipment should be used with extreme care. Incorrect use of
such equipment could damage components contained in the device.
It is not the intention of this manual to cover all details and variations in equipment, nor does
this manual provide data for every possible contingency regarding installation or operation. The
availability and design of all features and options are subject to modifi cation without notice.

SECTION 1 • GENERAL INFORMATION
GENERAL
The DVR
®
2000E is an electronic, solid-state, microprocessor-based control device. The DVR
®
2000E regulates the
output voltage of a brushless, ac generator by controlling the current into the generator exciter fi eld. Input power
to the DVR
®
2000E is from a multi-pole, high-frequency, permanent magnet generator (PMG).
The DVR
®
2000E is supplied in an encapsulated package designed for behind-the-panel mounting. The DVR
®
2000E
is held in place by thread-forming screws that thread into its plastic shell. Front panel indicators (LEDs) annunciate
regulator status and system conditions. DVR
®
2000E connections are made through quarter-inch, quick-connect
terminals on the rear panel. A 9-pin DB-9 type connector on the rear panel provides communication between the
DVR
®
2000E and an IBM compatible PC.
When the DVR
®
2000E Voltage regulator is mounted on the generator at the factory a molded cover is provided.
This cover allows the system to be in compliance with UL 508 as live terminals and heatsinks could be exposed
to unintentional contact. As stated this cover must be installed whenever the voltage regulator is energized.
FEATURES
DVR
®
2000E units have the following features and capabilities.
•
Four control modes: automatic voltage regulation (AVR), manual or fi eld 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 (OEL) limiting in AVR, VAR, and PF control modes.
•
Underfrequency (volts/hertz) regulation.
•
Crowbar circuitry protects the fi eld.
•
Overtemperature protection.
•
Three-phase or single-phase generator voltage (RMS) sensing/regulation in AVR mode.
•
Single-phase generator current sensing for metering and regulation purposes.
•
Field current and fi eld 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, DVR
®
overtemperature
® 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 DVR
®
2000E status and gives the ability
to make setting changes at the front panel.
•
Rear RS-232 communication port for personal computer communication using MARATHON-DVR
®
2000E-
COMS Windows® based software for fast, user-friendly, setup and control.
