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.
•

INITIAL ADJUSTMENTS
Read and understand the operation of the individual adjustments before attempting any initial adjustments.
Before starting the generator, the procedures in the following paragraphs should be performed.
Remove the 5 ampere fuse before starting the generator for the fi rst time. Perform all preliminary engine governor
adjustments without the regulator energized.
After initial governor adjustments are complete, reinstall the 5 ampere fuse and connect only the power input
leads or PMG leads to the regulator. Remove all other regulator connections that may be present and temporarily
insulate them.
Start and run the generator at rated speed. The regulator will perform the self-test and enter a shutdown mode. At
this time, initial adjustments can be made. To do this, step through each adjustment using the “SELECT” button.
For each adjustment, press the “UP” or “DOWN” button to obtain the desired level on the LED bar graph.

10
Section
2
After the initial adjustments are made, shutdown the generator and connect the remaining regulator leads. The
generator may be started and fi nal adjustments may be performed on the regulator.
MAKING SETTINGS CHANGES
The following paragraphs describe how the HMI is used to make setting changes.
Front Panel Operation
The LEDs indicate control mode and status conditions and are also used when adjusting settings at the front
panel. Repeatedly pressing the “SELECT” button steps through the various adjustments, starting with the “Course
Voltage” adjustment and progressing through to the “Fine Voltage” adjustment. The next press of the “SELECT”
button exits the adjustment mode.
When in the adjustment mode, only the adjustment LEDs will be lit. All mode status LEDs will be turned off.
Adjustment LEDs are of two types. The fi rst type is the LED that indicates the function being adjusted. This LED
blinks slowly (approximately once per second). The second type is the LED that indicates the level of adjustment.
This LED is on steady. The level of adjustment is changed by pressing the “UP” or “DOWN” button. When an
adjustment level LED (on steady) overlaps the function LED (slow blinking), the LED will remain in the slow
blinking mode. The setting is saved when the “SELECT” button is pressed. If no button is pressed for a period
of one minute, the regulator saves the settings and exits the adjustment mode. If regulator power is interrupted
before the save feature is commanded, that level of adjustment will be lost.
When the regulator is not in the adjustment mode and either the “UP” or “DOWN” button is pressed, the regulator
enters the “Fine Voltage” adjustment mode and changes the generator fi ne voltage set point by 0.1V. Successive
presses of the “UP” or “DOWN” button shall continue to adjust the fi ne voltage setting. Pressing the “SELECT”
button causes the regulator to exit the adjustment mode. Mode status LEDs blink approximately twice per
second.
