The DR175, DR250, DR300 and the DR350 use a
combination of four different Stamford generator ends,
depending on your operating voltage.
Review the Stamford Newage nameplate on your
generator before selecting the correct information below.
Some custom applications use other models. Check the
generator nameplate for actual model number.

INTRODUCTION
PRODUCT DESCRIPTION
This engine-generator set is designed for unattended
remote start operation. It can be operated as part of a
fully automatic standby power system or independently
as a local start unit in a prime power system. The engine-
generator set is fully tested at the factory prior to shipment
to insure proper operation of each individual component as
well as the total system’s performance and reliability.
The engine generator set consists of a multi-cylinder, liquid
cooled engine nominally operating at 1800 rpm. The
generator frequency regulation is maintained by the engine
governor to /- 1.5 Hz (cps), from no load to rated
load for standard mechanical governors and to /- .5
Hz or better for units equipped with an electronic governor.
The generator is a single bearing, direct drive, rotating field
design. The generator is connected to the engine flywheel
via flexible drive disks. Generator set is skid mounted with
isolation mounts between the engine and base on all units.
A customer supplied 12 Volt battery is required to complete
the installation. Battery requirements are listed later under
the battery installation section.
Unit Orientation Note: All references used in this manual
for unit familiarization, access and component locations on
the Generator Set are oriented from a TOP (plan) VIEW with
engine at the FRONT and generator to the REAR.
WINCO uses a common junction box for all customer
control and power connections (both AC output and DC
control). The common electrical junction box is always on
the left side at the generator end of the machine.
The engine is controlled and Generator Set operation
is monitored for safe operation by a programmable
microprocessor based electronic Engine Control Module
(ECM) with an LCD digital display. The generator set ECM
control is mounted on a vertical pedestal on the right side
of the generator. The ECM is programmed with a cycle
cranking sequence - 3 cycles of 15 seconds on/15 seconds
off, and 5 minute cool-down delay. The cool-down delay
can be changed in the field from 0 to 30 minutes by your
installer. Other features, timing cycles, set points, and
signal output capabilities are possible. Consult factory for
procedure and passwords.
NOTICE:
These units will automatically transfer if a power outage
occurs while running in exercise mode.
GENERATOR SET
Every WINCO generator set has its own unique identity
data plate. This data plate identifies the complete unit
model number, the system serial number, and has links to
the individual components that form the generator set in
our factory records. Several of the major components also
have their own individual data plates providing additional
information to document build data for warranty and
replacement parts.
