INTRODUCTION
ENGINE
Refer to the engine operators manual for more detailed operation and
maintenance information.
PRODUCT DESCRIPTION
CAUTION: EQUIPMENT DAMAGE:
Be sure to check the engine oil level frequently as specified in the
engine manual.
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 manufacturer has established an excellent worldwide
engine service organization; engine service is available from a nearby
authorized dealer or distributor. Go to the WINCO website for a list of
engine dealers (http://wincogen.com/Engine_Support) or contact the
WINCO Service Department.
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 within +/- 1.5 Hz
(cps), from no load to rated load for standard mechanical governors
and to within +/- .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.
The rated power of each engine-generator is limited by the
temperature, altitude, and all other ambient conditions specified by
the engine manufacturer. Engine power may decrease 3% for each
1000 feet above sea level, and will decrease an additional 3% for each
10 degrees Fahrenheit above 60° Fahrenheit. Units should not be
operated in ambient temperature greater than 122° Fahrenheit.
GENERATOR
A customer supplied 12 Volt battery is required to complete the
installation. Battery requirements are listed later under the battery
installation section.
WINCO generator sets use brushless, AVR (Auto-Voltage Regulator)
controlled broad-range generator ends. The generator converts
rotational mechanical energy into electrical energy. These WINCO units
are equipped with generators manufactured by Cummins Generator
Technology. Each generator ‘end’ has its own data tag. A unique serial
number is on the data plate.
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.
TRAILER/HOUSING
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.
These switchable voltage generators are normally shipped fully
enclosed & mounted on a trailer. The trailer is DOT approved and you
should receive a certificate of origin. This will allow you to register the
equipment and obtain tags from your state. If you should encounter any
problems registering the trailer, contact the WINCO Service Dept at
507-357-6831.
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.

COOLANT
WARNING:
The electrolyte is diluted sulfuric acid that is harmful to the skin
and eyes. It is electrically conductive and corrosive. The following
precautions must always be taken.
1. Always wear full eye protection and protective clothing.
2. Where electrolyte contacts skin, wash off immediately with water.
3. If electrolyte contacts the eyes, flush thoroughly and immediately
with water and seek immediate medical attention
4. Spilled electrolyte is to be washed down with an acid neutralizing
agent. A common practice is to use a solution of one pound
of bicarbonate of soda (baking soda) to one gallon of water.
The bicarbonate of soda solution is to be added until the evidence
of reaction (foaming) has ceased. The resulting liquid is to be
flushed with water and the area dried.
Before starting the engine, check the coolant level in the radiator. If
it is low, refill as specified in the engine manufacturer’s maintenance
instructions. The radiator should be filled to about 1 inch below the filler
neck. For additional information on engine coolant requirements, see
engine manufacturer’s maintenance instructions.
INSTALLING THE BATTERY
CAUTION:
In the following battery installation procedure, check to be sure the
DSE 7310 MKII is in the “stop” position. This should be your last step
before initial start-up.
DANGER: EXPLOSIVE FIRE RISK:
1. Never smoke when near batteries.
2. Do not cause a flame or spark in the battery area.
3. Always discharge static electricity from your body before touching
batteries by first touching a ground metal surface.
The RP25 is a 12 volt system and requires a single battery. The
batteries should be rated at a minimum of 650 CCA. Installation of the
highest CCA rated battery, within the correct BCI group, will increase
cold weather starting performance. Gel batteries should not be used
with the battery tender installed in the generator enclosure.
SERVICING BATTERIES
Installation and servicing of batteries must only be preformed or
supervised by personnel knowledgeable of batteries and the required
precautions. Keep unauthorized personnel away from batteries.
Batteries used on these units may, over time, lose water. This
is especially true if you are using a trickle charger to maintain
your battery. Different types of batteries require various types
of maintenance. Refer to the battery manufacturer for specific
recommendations.
When installing or replacing batteries, use the proper group/size
starting battery. The battery should be a maintenance-free lead acid
design. Deep cycle batteries will not work for this application.
NOTE: Always make sure that a new battery is fully charged before
installing it on a generator set. Failure to do so can cause damage to
the engine control module in the generator set.
CAUTION: PERSONAL DANGER:
NEVER dispose a battery in a fire. The battery is capable of exploding.
DO NOT open or mutilate the battery. Released electrolyte is known to
be harmful to the skin and eyes and to be very toxic.
All connections must be clean and tight. Depending on your battery
type, check the electrolyte in the battery periodically to be sure it is
above the plates. Never allow the battery to remain in a discharged
condition.
These engine-generator sets are all NEGATIVE ground. Be very careful
not to connect the battery in reverse polarity, as this may short circuit
the battery charging system on the engine.
CAUTION: EQUIPMENT DAMAGE:
Never attempt to jump start this engine. If the battery should
accidentally become discharged, disconnect the battery cables and
recharge the battery before attempting to start the unit. Boost/jump
starting this unit improperly will result in PERMANENT DAMAGE TO
THE ENGINE CONTROL MODULE (ECM).
CAUTION:
A battery presents a risk of electrical shock and high short circuit
current. The following precautions must be observed when working
with batteries:
1. Remove watches, rings, and other metal objects.
2. Use tools with insulated handles.
3. Check both the battery cable ends and the battery posts to be
sure they are free of corrosion.
4. Always connect the battery positive cable first and then connect
the battery negative cable. When removing the battery cables
from the battery, reverse the procedure, disconnect the negative
first and then the positive cable.
5. Be sure all connections are tight and coat the terminals and cable
ends with dialectic grease.

BATTERY CHARGER & BLOCKHEATER
meter and the service entrance, providing the service entrance ampere
rating is within the transfer switch’s rated capability.
A three-stage electronic battery charger is provided standard on this
unit. This charger has three rates of charging. During the first mode,
known as Bulk charging, the charging current is limited to 2 Amps at a
voltage of up to 14.5 VDC. The green LED will blink during this stage.
During the Absorption mode, the charger holds the battery voltage at
approximately 14.5 VDC, and then gradually reduces the amount of
Amps it delivers to the battery. This way the battery is able to “absorb”
the last 10% of charge as quickly as possible without becoming
overheated. The green LED will blink during this stage. When the
battery approaches full charge, the charger switches into its third
charging stage, gradually reducing the current fed to the batteries to
as low as 0.1 Amps. At the same time, it reduces its output to a “Float”
or “Maintenance” charging rate of approximately 13.3 VDC nominal,
indicated by the green LED. This low “Float” or Maintenance” voltage
gently “tops off” the battery, keeping it fully charged and ready until
needed. The green LED will indicate the battery is fully charged.
If only specific circuits are to be powered under emergency power
failure conditions, an additional distribution panel designated
“emergency distribution panel” must be installed.
All selected emergency circuits are removed from main distribution
panels and installed in the emergency distribution panel. The ATS is
then installed between the main panel and the emergency distribution
panel. Suggested circuits: freezer, refrigerator, furnace, emergency
lights, sump pump, emergency outlet circuits, etc. Total running load
must not exceed generator rating.
The blockheater on this unit is 1000 watts and should also be plugged
in the Shore Power receptacle. The block heater is thermostatically
controlled and when plugged in will maintain the engine coolant
temperature between 100 and 120 degrees F.
MOUNTING THE AUTOMATIC TRANSFER SWITCH
For standby applications, an automatic transfer switch (ATS) will
be necessary for automatic starting. A wall mounted ASCO 300
ATS designed for inside or outside installation. The transfer switch
is UL1008 approved. A fourteen day electronic exerciser circuit is
installed in the ATS as standard equipment. The ATS also contains the
power failure sensing circuitry necessary to start and stop the engine
generator set. The transfer switch is also equipped standard with a 3
second start delay, and a 15 second transfer delay to allow the engine
to warm up before transferring the load to the generator. When the line
power is restored the ATS has a 5 minute transfer delay to allow the
incoming utility to stabilize before transferring back to line power and
then an additional 1 minute engine cool down delay before the engine
shuts down. Read and understand the ATS owners manual before
installing, servicing or operating the transfer switch.
WARNING: FIRE HAZARD:
All wiring must be done by a licensed electrician, and must conform to
the National Electrical Code and comply with all the local codes and
regulations. Check with the local authorities before proceeding.
INSTALLATION NOTES:
Because of many different types of service, feeder and distribution
equipment, no specific wiring instructions can be provided. It is
recommended that only copper wire be used. In all cases it is
essential that while the load is connected to the generator, there can
be absolutely no feedback from the generator to the power line or the
power line to the generator. When properly installed, the normal ATS
Control and safety system will eliminate all paths and feedback.
To wire the automatic transfer switch into existing wiring, first determine
which circuits will be on the emergency load circuit. If the entire load is
transferred, the transfer switch can be wired directly after the watt-hour

WARNING: POTENTIAL EQUIPMENT DAMAGE
The 120/240V three phase position has a wild leg that produces 208V
line to neutral on G2. Be sure when connecting to your panel or load,
that you match the wild phase on the generator to the wild phase in
your panel or load. failure to do so will result in 120V devices receiving
208V. You must also match your rotation.
Before wiring and starting this unit, be sure you have the selector
switch set for the right voltage. You must depress the safety switch
below the selector switch to change the position of the voltage selector
switch. If the unit is running, depressing this switch will shutdown the
engine-generator set.
DO NOT jump start these engine-generator sets. Starting these units
on a low battery or jump starting them will cause damage to the engine
control module.
Use the following check list to verify correct installation before starting
the engine.
□ Engine oil. Fill as required with proper grade/qty.
□ Engine coolant. Fill as required with proper mixture.
□ Unit mounting base properly bolted down.
□ Clearance for service and maintenance on all sides.
□ Proper fuel line material and size.
□ All fuel line connections tight.
□ Battery connections clean and tight
□ Battery fully charged.
□ All AC and DC wiring installed and properly protected.
After completing the previous checklist, the engine-generator set is
ready for initial start-up.
MANUAL MODE
1. Select the desired voltage with the selector switch.
2. Turn off both main line circuit breakers.
3. Press and release the MANUAL MODE button. The small LED light
next to it should come on.
4.. Press and release the green START ENGINE button. The DSE
7310 MKII will send a start signal to the glow plug solenoid on the
engine. Preheating the engine for about 10 seconds at the end of that
time will engage the fuel rack solenoid and the starter. This will start the
cranking cycle (10 seconds on and 10 seconds off).
Note: There is no start delay in this mode of operation.
If the engine fails to start during this cranking period, the starter motor
is disengaged and goes into a rest mode after which a second attempt
is made to start the engine. Should this sequence continue through 3
cranking cycles the start sequence will be stopped and the display will
show ‘FAILED TO START”.
All engine functions are controlled by the DSE 7310 MKII controller.
Once the unit is running, the control will display the engine information,
To get the generator information, scroll down on the controller.
At the same time you are making the voltage selection, you must also
adjust the setting on the mainline circuit breaker to give the proper
breaker protection. If you have any doubts as to the voltage in your
area compare your incoming power or load name plates.
The AC ouptut readings displayed on the DSE 7310 MKII are collected
through the AC interface harness wired in the generator control box.
Any shutdowns related to the AC output are a function of the controller
are based on information collected in the DSE 7310 MKII via this AC
harness.
INITIAL START UP
5. After the engine is running at the proper speed, adjust the voltage to
the desired level using the external voltage trim rheostat.
WARNING: EQUIPMENT DAMAGE:
Before attempting to start this unit, complete your pre-start checklist
and ensure the generator mainline circuit breaker is in the proper
position prior to starting. Starting this unit without it properly connected
can cause serious personal injury or equipment damage.
6. Turn on the proper main line breaker (either high or low voltage) and
padlock the lock bar to prevent the incorrect breaker from being turned
on.
OPM-114

REV B
WARNING: EQUIPMENT DAMAGE:
Never apply a load to the generator until you have first checked the
voltage at the terminal blocks or Cam-Locks.
7. With the engine running smoothly check the no load voltage and
frequency on the digital display. The voltage should be 208/240/480 AC
depending on which model you have and a frequency of 59.5 to 60.5
hertz (Hz).
If you have the proper voltage at the generator the next step is to check
the voltage at the generator terminals. The voltage between the L1, L2,
and L3 terminals should be the same as it was on the generator front
panel. The voltage should also be checked between the hot terminals
(L1, L2, and L3) and the N to be certain of a balanced voltage output
and a solid neutral connection.
ON 240 VOLT (DELTA) SYSTEMS BE SURE YOU KNOW WHERE
THE HIGH VOLTAGE “WILD” LEG IS. IT MUST BE IN THE SAME
LOCATION ON THE LINE SIDE AS IT IS ON THE GENERATOR SIDE.
NOTICE:
If for any reason during the check out procedure the voltage and
frequency are not correct, depress the STOP/RESET button and
correct the trouble before proceeding.
8. Stopping - There are two ways to stop the unit when it is in the
manual mode. Pressing the STOP/RESET button will stop the unit
immediately. Pressing the AUTO mode button will stop the unit but only
after the cool down timers have timed out and there is no remote start
signal being sent to the unit.
AUTO MODE
1. Complete the previous Manual Mode starting procedure to ensure
the system is set up properly.
2. Ensure the engine is in the OFF position during installation of the
remote start connections.
3. Locate the remote start terminal block. This terminal block is located
next to the full power connections, behind the access door on the
control panel.
4. Locate the remote start terminals in your remote automatic transfer
switch (ATS). The RP25 requires a contact closure for start.
WARNING: EQUIPMENT DAMAGE:
The remote “signal” must be a “dry” (non-powered) contact closure.
Using a power contact will cause permanent damage to the engine
control module.
8. Connect the load block to the transfer switch using the proper wire
sizes. Refer to the National Electric Code Handbook (NFPA 70) for
proper wire type and sizing. Use Table 310-16 for wiring run through
conduit and table 310-17 for free air wiring.
Use extreme caution when installing the delta voltage pattern. One
power leg of this 3-phase pattern produces 208V measured from line
to neutral. Be sure to match the location of the generator wild leg to the
location of the wild leg on the incoming power service. Failure to do so
will cause equipment damage to any 120V load incorrectly connected
to this line.
9. Connect the neutral to the transfer switch using the same size wire.
10. For isolated neutral operation, remove the jumper wire between the
ground lug and the neutral connection block. Then route a ground lead
back to system ground.
11. Ground the generator with an eight foot copper ground rod or other
approved grounding system. Connect #4 AWG copper cable from the
ground lug on the generator to the ground rod.
12. Depress the RUN button on the RP25 control panel to start it.
13. Check the voltage at the ATS. Verify that it matches the incoming
power line voltage line-to-line and line-to-neutral on each leg.
14. Check the three phase rotation pattern. Ensure that you have the
same rotation, with both the generator and the normal power source.
15. Depress the STOP button on the front of the engine control.
Let the unit stop and depress the AUTO button. The unot is now in
AUTOMATIC mode. Also be sure the AUTO light is lit on the control,
letting you know it is in auto mode. See control panel layout for
additional information.
16. To test the Automatic Transfer Switch, follow the instruction on the
operator’s manual that came with the transfer switch. If you get a fault
during the initial start up or prior to start up, it is most likely a false
warning light. Simply reset the ATS start over.
17. Once you have completed testing of the ATS, be sure you ALWAYS
leave the system in the standby mode,unless servicing the unit. For
standby operation, press the AUTO button on the front of the control.
The green light should light up next to the AUTO button.
NOTE: For setting the exerciser circuit, for all ATS, see the operator’s
manual shipped with the ATS.
5. For most installations, 16 gauge wire is sufficient to handle the
control signal. On extremely long runs, increase the wire size to
minimum voltage drop.
6. Locate and identify the “neutral” and “generator” connections in the
ATS.

VOLTAGE REGULATOR WIRING
WARNING:
All wiring must be done in accordance with National Electric Code
NFPA 70.
AS440 Automatic Voltage Regulator
There are three ways the loads may be connected to the RP25:
1. Front Panel A variety of receptacles have been provided for your convenience
on the front panel. The 120V receptacles are powered when the
voltage selector switch is in the 120/240 single phase, 120/40V three
phase, and 120/208V three phase position. The 240V receptacles
are only usable in the 120/240V single phase and 120/240V three
phase position. In the 120/208V position, the 240V receptacles have
only 208V at them. Refer to the voltage output table, located
previously in this manual.
2. Full Power Load Connection Terminal Block For remote connections and connecting load distribution boxes,
heavy duty terminal blocks have been provided. These terminal
blocks are located on the rear of the unit justs below the DSE7310
MKII controller. The neutral and ground are connected together
at this panel. For use with an isolates neutral, remove the jumper
strap between the neutral connection block and the ground lug. This
will isolate the neutral from the ground and allow your a single point
grounding at a distribution panel. When using these terminal blocks,
be sure to use wire rated large enough to carry your full load or the
full rated load of the generator.
3. Full Power Cam-Lock Connections For ease of connecting and disconnecting loads, these units have
been equipped with Cam-Locks located behind the right hand, rear
door. See the Cam-Lock Connections in this manual. Instructions
for the Full Power load Connection Terminal Block apply for the
Cam-Locks. If you need to run an isolated neutral system, the
jumper between the neutral and ground musts be removed at the
terminal block.
4. Grounding The Unit To comply with current safety standards, this generator set must be
properly grounded. Ground the RP25 by driving an eight foot copper
ground rod into the earth. Then connect a #4AWG ground cable
from the grounding lug on the generator to the ground rod.
The following is a list of connections on the AVR. These have been
factory set and other than voltage adjustment, should never be
changed.
VOLTS
To adjust generator output voltage.
Clockwise to increase voltage.
STABILITY
To prevent voltage hunting.
Clockwise to increase the dampening effect.
STANDARD CONNECTIONS
Terminals 1 & 2 will be fitted with a shorting link if no hand trimmer is
required.
Terminals La & Lb are linked only for special low voltage applications.
UFRO - Under Frequency Roll Off
Terminal S1 is connected to the C.T., S2 on the AVR.
DROOP - Normally preset in the works to give 5% voltage droop at full
load zero power factor.
Terminal A1 is connected to the AVR 0 Volts. Positive on A2 increases
excitation, negative on A2 decreases excitation.
TRIM - allows the user to adjust the sensitivity of the input.
LED Indicator Light - indicates over excitation condition or under speed
running.
50 CYCLE OPERATION
With a couple of minor changes, these mobile diesel generators are
capable of producing 50Hz power. Two changes must be made:
1. The engine must be reduced to 1500 RPM governed speed.
Consult your local Isuzu service center for the proper procedure
for reducing engine speed and setting up the governor to operate
at 1500 RPM.
2. The automatic Volt/Hz regulator must be also reset to operate at
50 Hz. Refer to the Stamford generator manual for instructions.

MAINTENANCE
TROUBLESHOOTING TABLE
The ultimate aim of a preventive maintenance program is to maintain
the equipment in optimum condition, for the maximum amount of time
during it’s useful life. The detection of faults before they develop into
major problems will decrease downtime. A regular schedule of cleaning
and inspection will help assure trouble-free operation. Personnel
responsible for maintenance should set up a schedule for inspection,
and cleaning at intervals calculated to keep the equipment in good
condition. In making up a schedule, keep the following in mind:
NOTE: Before doing any trouble shooting, check the digital display on
the DSE 7310 MKII. Normally, it will tell why the unit has failed. This
will shorten your trouble shooting time and in many cases, prevent the
replacement of parts that may not be defective.
