SECTION 1 - OVERVIEW
SAFTY AND PRECAUTIONS
When the DVR®2000E+ Voltage regulator is mounted on the generator at the factory a molded cover is
provided. This cover prevents exposure and unintentional contact. This cover must be installed whenever the voltage
regulator is energized.
:Use caution when working around the component side of the DVR®2000E+. Voltage levels
may be present at the exposed components and contacts when the unit is energized.
GENERAL
The DVR®2000E+ is a microprocessor-based control device that regulates the output voltage of a brushless, ac
generator by controlling the current into the generator exciter field. Input power to the DVR®2000E+ is derived
from a single phase, 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. The front panel display
annunciates regulator status and system conditions. DVR®2000E+ connections are made through four types of
connectors:
•Tenquarter-inch,quick-connectterminalsforgeneratorconnections
•Two12-pinDeutsch(DTCstyle)connectorsforcurrenttransformer(CT)andsystem
interface connections
•One3-pinAmp/TycoMiniMate-N-LokreceptacleforCANbusinterface.
•One9-pinDB-9typeconnectorforcommunicationbetweentheDVR®2000E+ and a
Windows®compatible PC.
FEATURES
DVR®2000E+ has the following features:
•Threeregulationmodes:singlephaseautomaticvoltageregulation(AVR1),threephase
automatic voltage regulation (AVR3) and field current regulation (FCR)
•Presetstabilitysettings
•AdjustablesoftstartinAVR1orAVR3regulationmodes
•Underfrequency(volts/hertz)regulation

WARRANTY
When supplied on a generator, the DVR®2000E+ carries the same warranty as the generator. (a) Marathon
warrants Standby Duty Generators manufactured by or for it to be free from defects in materials and workmanship
and to conform to Marathon’s written specifications for a period of 24 months from date of startup or 30 months
from date of shipment or 1000 hours in use, whichever period shall expire first. (b) Marathon warrants Continuous
Duty Generators manufactured by or for it to be free from defects in materials and workmanship and to conform
to Marathon’s written specifications for a period of 12 months from data of startup or 18 months from date of
shipment, whichever period shall expire first.
When supplied as a separate component, Marathon warrants the DVR®2000E+ to be free from defects in
materials and workmanship and to conform to Marathon’s written specifications for a period of 12 months from
date of shipment.
