INTRODUCTION
TESTING POLICY
Before any generator is shipped from the factory, it is fully
checked for performance. The generator is loaded to its
full capacity, and the voltage, current, and frequency are
carefully checked.
Rated output of generator is based on engineering tests
of typical units, and is subject to, and limited by, the
temperature, altitude, fuel, and other conditions specified
by the manufacturer of applicable engines.
PRODUCT DESCRIPTION
The engine-generator set consists of a multi-cylinder, liquid-
cooled engine nominally operating at 1800 RPM. This
generator set meets current EPA regulations for standby
use only. The generator frequency regulation is maintained
by the engine mechanical governor to within +/- 1.5 Hertz.
The generator is connected to the engine flywheel via
flexible drive disks. The generator set is skid mounted with
isolation mounts between the engine and base.
NOTICE:
A Customer supplied 12 Volt battery is required to complete
the installation. Battery requirements are listed later under
the battery installation section.
The generator ships with an advanced DSE7310 digital
controller. The DSE7310 will electronically display useful
engine and generator performance information. The
controller starts and stops the generator and monitors
critical operating parameters and will shut the generator
down to protect the engine from damage.
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
replacements parts. Be sure to have the main WINCO unit
data plate information recorded inside the front cover
of this manual for future reference and for identification
whenever requesting field or factory assistance.
Primary fields needed for assistance are complete model
number and serial number.
ENGINE:
This manual covers specific operation of the combined
engine generator set. The basic engine information
provided in this manual is not suitable for all operating
conditions. Refer to the engine operators manual for more
detailed operation and maintenance information.
CAUTION: EQUIPMENT DAMAGE
Be sure to check the engine oil level frequently as specified
in the engine manual.
The engine manufacturer has established an excellent
worldwide engine service organization; engine service is
available from a nearby authorized dealer or distributor.
The rated power of each engine-generator is limited by
the temperature, altitude, and all other ambient conditions
specified by the engine manufacturer.

GENERATOR:
The nameplate includes a standby rating. The standby
rating is the maximum amount of power the generator set
can produce.
WINCO generator sets use a 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
Technologies. Each generator ‘end’ has its own data tag. A
unique serial number is on the data plate and the data label
is affixed to the main frame on the generator on the left
side.

move the generator. As the distance from the forklift mast
increases the lifting capacity for the forklift decreases. When
lifting from the side the forks should extend the entire width
of the unit to the opposite side frame rail.
CAUTION
Do not attempt to lift the generator set by the means of
the lifting eyes on the engine or generator end. These
lifting points are only for the use during the manufacturing
process and are designed for lifting of the individual gener-
ator set components.
WARNING
NEVER attempt to lift the fuel tank filled with fuel. Sloshing
of the fuel can cause a shift in the balance of the fuel tank,
making for a DANGEROUS, unbalanced lifting load. If the
generator was shipped on the fuel tank, use the lifting
points located on the fuel tank to move the entire gener-
ator set into place. DO NOT PLACE FUEL IN THE TANK
PRIOR TO LIFTING.

LIFTING THE GENERATOR SET
NOTICE: PERSONAL INJURY
To prevent injury to persons or equipment, observe the
following guidelines when lifting the generator:
Due to the different designs, configurations, options,
weights, site conditions, and available material handling
equipment, specific lifting instructions are not provided for
each individual generator set model. General guidelines
provided are applicable to the entire generator line. It
is the responsibility of the installing party to follow the
lifting equipment’s operator’s manual to prevent injury to
personnel and damage to the generator.
Smaller generator sets may not require use of overhead
lifting equipment and may be placed on the pad with basic
material handling equipment, i.e. a forklift. Always use
forklifts of a proper rating and with long enough forks to

VENTILATION REQUIREMENTS
OPEN SKID
WARNING: EQUIPMENT DAMAGE
It is the installer’s responsibility to ensure that there is
sufficient cooling air available to prevent the engine and
generator from over heating. Damage caused by overheat-
ing is not covered by warranty.
Providing proper air movement during your installation
planning is essential. You will need to provide a fresh air
inlet as well as a hot air outlet (to the outside of protection
housing) for proper engine performance. These engine-
generator sets are equipped with unit mount radiators and
the engine is equipped with a pusher type fan. The hot
air from the face of the radiator must be ducted out of the
enclosure to ensure proper cooling. Failing to do so will
allow the hot air to recirculate around the radiator causing
the engine to overheat, resulting in an engine shutdown
and damage. If louvers are used in front of the hot air duct
to protect the unit from outside weather, the louvers should
be 1½ times as large as the area of the radiator face to
prevent back pressure.
Foam or other seals can be used to form a tight lip forcing
all of the air from the engine fan out of the enclosure.
In addition to a hot air discharge, you must plan a fresh air
intake opposite the radiator discharge. Their fresh air inlets
should be 1½ to 2 times larger than the radiator face. The
extra air inlet area is required to minimize restriction and
to provide combustion air for the engine. Do not block
fresh air intakes with other equipment as this will result
in insufficient air flow to the engine for cooling. Installing
them opposite the hot air discharge will allow a sweeping
flow of cooling air across the engine, preventing hot spots.
The WINCO installation manual OPM-112 contains
additional information on indoor, open skid installations
and is available electronically through our website or by
requesting a copy from the factory.
EXHAUST INSTALLATION
WARNING: PERSONAL INJURY
Improper exhaust installation will allow dangerous gases
to seep into enclosed spaces causing a hazard to your
health and/or death.
All exhaust must be piped out of the enclosure. When
selecting a location to exhaust fumes make sure that the

INSTALLATION
This unit should be installed in a well ventilated area,
ensuring the exhaust air cannot be recirculated back into
the engine.
CAUTION
This unit will get hot while it is running and for some time
afterward.
WARNING: PERSONAL INJURY
Before proceeding with the installation, be sure the engine
control is in the “stop” position and the emergency stop
depressed. Also, be sure the generator MLCB (main line
circuit breaker) is in the “off” position and the unit starting
battery is disconnected.
GENERAL INFORMATION
Before beginning the installation process, recheck the
voltage, phase, and amperage rating of the generator
set. Be certain it can handle the intended load and are
compatible with the intended loads. Plans for installation
should be prepared with proper attention to mechanical
and electrical engineering detail to assure a satisfactory
system installation.
The information in this manual is offered only as a guide to
finalizing your installation plans.
NOTICE: For full service switching of the entire load, the
ATS must be ‘SE’ (Service Entrance) rated or must have a
properly rated fusible disconnect installed before the ATS to
protect the contacts.
ENGINE GENERATOR SET MOUNTING
This engine-generator set is generally supplied as weather
enclosed packages for quick installation on an outdoor
concrete pad. They are also available as open skid mounted
units for indoor installation in a building or protective
enclosure, properly ventilated, supplied by the installer.
The factory weather enclosures are acoustical housing
intended for outdoor installation only. Factory weather
enclosed units are not intended to be used indoors and
no support is available to assist in re-engineering finished
packaged units. The unit should be mounted to allow
ample working room around it. A general rule to follow is
to allow 24 inches or more of clearance for maintenance.
Follow local codes for clearance from combustible surfaces.
The unit’s main frame must be bolted securely to a solid
base. The engine-generator is mounted on channels which
are attached with special shock mounts to the main frame.
This allows the engine-generator free movement without
affecting the base or surrounding equipment.
WARNING: EQUIPMENT DAMAGE:
Never mount these engine-generator sets to a wooden
base/structure. Over time, the wood will deteriorate and
the unit mountings will come loose. These units must be
mounted to a steel or concrete base.

OPM-135/D
Open skid mounted Diesel units are often supplied with
capped inlet and return lines. The use of a sustainable
customer supplied flexible fuel line is essential between
the engine and fuel supply to provide a vibration break
between your fuel supply and the engine.
A.C. ELECTRICAL CONNECTIONS
NOTICE: CLASS 1 WIRING METHODS ARE TO BE USED FOR
ALL FIELD WIRING CONNECTIONS TO TERMINALS OF A
CLASS 2 CIRCUIT
WARNING
A mainline circuit breaker has been provided inside the
generator housing. During all wiring installation, make
sure the breaker is in the off position and the generator is
disabled.
WARNING:
Make sure the generator is disconnected from the battery
to prevent accidental starting.
The connection box shown are typical arrangements.
A. NEUTRAL LUGS:
These lugs are isolated from ground and provided for you
to connect your neutral wire from the transfer switch to the
generator.
The 225 Amp terminal block lugs will handle wire size #4 to
300 MCM and should be torqued to 250 in. lbs.
B. GENERATOR CIRCUIT BREAKER:
This circuit breaker provides overload protection for the
generator. Your power feeds from the transfer switch
will connect the bottom lugs on the circuit breaker. The
generator power feeds have already been wired into the
upper lugs.
Please refer to the circuit breaker installed on your unit for
breaker lug capacities and proper toque specifications.
To select the proper conductor size between the generator
and the ATS, first look your model up in Table 1 of Appendix
“A” for your generator amperage, found further in this
manual. Then refer to Appendix “2” for guidance on wire
sizing based on both wire type and amperage.
For additional information on wire sizes, refer to table 310-
16 of the National Electrical Code ANSI/NFPA 70.
C. GROUND LUG:
These ground lugs are bonded to ground and are provided
for you to connect your ground wire from the transfer
potential for contact with people is controlled. Exhaust can
enter buildings through windows, ventilation systems and
other openings if proper precautions are not followed.
The exhaust must be isolated from the vibration of the
engine. If the exhaust is connected in a rigid system it will
result in damage to the engine. The generator comes
equipped with an engine mounted flex pipe to aid your
installation. Ensure proper alignment with the generator.
The flex can be eliminated if it is pushed to one side to make
a connection.
The most direct path possible should be used to get to the
outside of the enclosure. Each bend restricts the pipe and
increases back pressure. It may be necessary to increase the
exhaust pipe diameter in some applications.
The exhaust pipe is very hot. When passing through the
structure it is critical that a thimble or other appropriate
technique is used to dissipate the heat and prevent the
structure from catching on fire.
It is preferable to exhaust out the side of the enclosures.
Slope the pipe slightly downward away from the engine
to cause any water in the exhaust to run away from the
engine. Do not exhaust near intake. Once outside the
enclosure a rain cap or other technique must be used to
keep water out of the exhaust. In mobile applications make
sure the rain flap faces to the rear of the vehicle so that it is
not blown open during transportation.
The generator ships with a critical grade muffler that should
be installed to decrease noise. It can be mounted either
internally or externally to the enclosure. The muffler cannot
increase back pressure to more than 0.725 psi.
INSTALLING THE FUEL LINE
WARNING: FIRE DANGER
Connecting rigid fuel line (i.e. steel or copper line) directly
to the inlet fuel filter or fuel pump may cause the fuel line
to crack during operation creating a serious fire hazard.
The fuel supply should be as close to the engine as
possible. This will reduce the installation cost of fuel runs
and minimize line losses. The diesel fuel supply should be
no more than 3 feet below the fuel inlet on the pump. If
your fuel supply is lower than three feet you may have to
install an additional lift pump to bring the fuel up to the
mechanical fuel pump on the engine.
The information in this manual is offered to assist you in
providing the proper fuel for your engine. However, this
information is only provided to inform you of the engine’s
requirements and assist in making you aware of the
decisions you must make. In no case should the instructions
or information provided be interpreted to conflict with any
local, state, or national codes. If in doubt, always consult
your local fire marshal or fuel supplier.
Engine generator sets are properly adjusted before they
leave the factory. Connecting a fuel supply with adequate
supply volume is critical to reliable operation. Diesel units
with optional base mounted fuel tanks are pre-plumbed to
the mechanical fuel pump on the engine.

9OPM-135/D
switch to. The lugs will accommodate #10 AWG to 2/0
AWG and should be torqued to 200 in. lbs.
D: 120V GFCI CIRCUIT TERMINAL BLOCK:
These terminals are rated for 85 Amps and will handle wire
sizes #4 AWG to 18AWG. They should be torqued to 16
in. lbs. This circuit must be fed from a fused circuit in the
distribution panel and provides power for the block heater
and the battery charger.
E: 120V/20 AMP DUPLEX RECEPTACLE:
This convenience receptacle is used to power both battery
charger and block heater. This circuit must be fed from a
GFCI fused circuit in the distribution panel.
F: NEUTRAL TO GROUND LEAD LUG:
This lug is provided on the neutral terminal block to allow
you to run a neutral to ground lead if you are using the
generator in a stand alone application. This would be an
application where there is not a distribution panel and
no other ground to neutral bond in the wiring system. If
a grounding wire is attached here, remove the floating
neutral label in the panel. This will not be used when you
are wiring a generator and transfer switch into an existing
power system.
WARNING
A mainline circuit breaker has been provided inside the
generator housing. During all wiring installations, make
sure the breaker is in the OFF position and the generator
operating switch is in the OFF position.
WARNING: EQUIPMENT DAMAGE
When installing a three-phase 240 Volt system, be sure
you know which lead is the high voltage “wild” leg (208
Volt line to neutral). The generator normally carries the
high voltage on the G2 lead.
All wires should be installed in rigid or flexible conduit
(knockouts are provided in the control box).
GROUNDING
A grounding lug has been provided on the engine
generator set and the generator set must be properly
grounded to good earth ground. Generally an 8 foot
copper rod driven into the earth will provide a proper earth
ground.
D.C. ELECTRICAL CONNECTIONS
All DC connections are completed on the terminal strip
just below the engine control. All DC connection must be
separate conduit. You cannot mix AC and DC leads at the
same conduit.
CONNECTION BOX TERMINALS
To install the wires, reference the following picture. Use a
small flat head screwdriver to push the release spring inside
the square hole (A). While the release is being pushed,
insert the wire into the larger circular hole (B). Remove the
screwdriver to secure the wire into place.
AB
REMOTE START
The DSE7310 is able to start the generator when it receives
a remote signal from any dry contact. This makes the system
compatible with a wide range of control mechanisms
including two-wire start automatic transfer switches. When
the contact closes the controller will automatically start.
When the contact is opened the generator will go through
a cool-down cycle and turn off. Connect the remote start
leads to the Remote Start + and Remote Start - terminal
blocks in the door behind the DSE 7310 controller.
Depending on the distance, 14 to 16 gauge stranded wire
should be used. It is suggested that these wires be labeled
S1 and S23.
Note: Any relay closure can be used to start and stop this
generator. As long as the contact stays closed the engine
generator set will continue to run. Once the relay is opened
the unit will shut down and remain in the standby mode
until the remote start relay is closed again.
E STOPS
In some applications additional emergency stops may be
desired or necessary. The controller has terminals designed
allowing the addition of multiple remote emergency stops.
E-stops must be normally closed to work properly in this
system. The e-stop circuit supplies power to fuel solenoid
and the starter circuit. Opening any switch in the series
prevents the engine from cranking or from receiving fuel to
run.

CAUTION
A battery presents a risk of electrical shock and high short
circuit current. The following precautions must be ob-
served 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 termi-
nals
and cable ends with dialectic grease.
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.
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.
SERVICING 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.
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.
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.
To wire additional emergency stop switches first remove
the orange jumper between the two Emergency Stop
terminal blocks. Failure to remove the jumper will prevent
the remote switches from working properly. Add wires
between the terminal block to the new switch(s). The
switches must be wired in series for proper function. Test
each e-stop after wiring to ensure they function properly.
SERIAL COMMUNICATION
DSE provides a series of remote accessories that can help
provide useful information to operators. These accessories
communicate over the DSE Net. Terminal blocks are wired
to the distribution panel to aid in installation. Follow the
instructions included with each accessory.
The generator controller can communicate with a variety
of controls and monitoring systems, including RS232 and
RS485. The ports are wired onto the back of the DSE7310.
In order to finalize communication the program will need
to be adjusted using the free DSE configuration software to
enable the commutation. Contact Winco service for a list of
register values.
INSTALLING THE BATTERY
CAUTION
In the following battery installation procedure, check to be
sure the DSE7310 is in the “stop” position. This should be
your last step before initial start-up.
A customer supplied Group 24/350 CCA battery is required
to complete the installation. Installation of the highest CCA
rated battery, within the correct BCI group, will increase
cold weather starting performance.

not work for this application.
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.
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.

BATTERY CHARGER & BLOCK HEATER
BATTERY CHARGER
A three-stage, on-board marine battery charger is provided
standard on this unit. The charger is a 5 amp dual use
maintainer and charger designed to keep your batteries
fully charged by maintaining them automatically.
Make sure all DC battery connections are tight and clean.
Follow battery manufacturer’s recommendations.
This charger is mounted under the customer connection
on the control side of the generator. The charger will
need to be plugged to a customer’s power source, using
a customer supplied heavy duty, UL approved extension
cord. The receptacle is to be powered by a GFCI circuit and
installed in accordance to the US National Electric Code. It is
suggested that this circuit be fused to 20 Amps.
Low/Charge Mode:
The illuminated blue power LED and red low/charging LED.
This indicates the Low/Charge mode is in process. When
completed the RED Low/Charge LED will turn off.
Auto Maintain Mode:
The illuminated Green auto maintain LED. This indicates
your 12 volt battery is fully charged. During short or long
term storage periods, Auto Maintain (Energy Saver) mode
will monitor and auto maintain a battery only when needed
to maintain a full state of charge. This feature significantly
reduces AC Power consumption, lowers operating costs
and maximizes reserve power performance.
BLOCK HEATER
The block heater on this unit is a 1000 watt heater and
can use the same 20 Amp GFCI fused circuit. The circuit
will terminate on the 120 Volt terminal block mount in the
customer connection cabinet. The engine block heater
installed on this unit should also be plugged into this
receptacle. The block heater is thermostatically controlled
when plugged in will maintain the engine coolant
temperature between 100 and 120 degrees F.

OPM-135/D
STARTING PROCEDURE
CAUTION
For the first 10 seconds of operation all of the oil, coolant,
and electrical shutdowns are disabled. This is enough time
to cause catastrophic damage to the equipment if the
pre-start checklist is not properly completed and proper
maintenance isn’t consistently followed.
NOTE: Cold start capabilities are strongly correlated with
the quality of the diesel.
LUBRICATION
Before starting the engine, check the oil level in the
crankcase. If it is low, refill to the full mark with the proper
weight/grade of oil as recommended by the engine
manufacturer’s maintenance instructions. The necessity of
using the correct oil, and keeping the crankcase full, cannot
be over emphasized. Failure to use the proper oil and keep
the crankcase properly filled will cause excessive engine
wear and shorten its useful life.
WINCO recommends our 5W-30 fully synthetic heavy duty
engine oil to give you maximum cold weather protection
while maintaining excellent performance in warmer
weather. We have partnered with a national lubrication oil
manufacturer to give you access to Winco private branded
premium oil available at comparable prices to conventional
oils. See your dealer for additional information.

CAUTION: PERSONAL INJURY
Only check oil when the engine is not running and is at a
low temperature in order to avoid the risk of burns.
1. Remove the dipstick and ensure the oil level is between
the Min and Max limits.
2. If it is difficult to read the level of the oil, clean the
dipstick using a clean cloth and then put it back into
its seat. Remove the dipstick again and check the level.
3. If level is low, unscrew the cap and refill with
suitable oil using the previous table.
COOLANT
Before starting the engine, check the coolant level in
the radiator. If it is low, refer to Refilling Coolant in the
Maintenance section of this manual. 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.
CAUTION
Both too high and too low of coolant temperature can
cause an engine malfunction. While the engine is running,
ensure the coolant temperature is within appropriate tem-
perature (167 - 194°F).
PRE-START CHECK LIST
There is a Pre-Start & Warranty Form that must be filled out
by an Authorized WINCO Service Center. After completing
the checklist, the engine-generator set is ready for initial
start-up.
WARNING: EQUIPMENT DAMAGE
Before attempting to start this unit, complete your pre-start
checklist and ensure the generator mainline circuit break-
er (if installed) is in the proper position prior to starting.
Starting this unit without it properly connected can cause
serious personal injury or equipment damage.
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.

13 OPM-135/D
SHUTDOWN
Shutdowns are critical alarm conditions that stop the
engine and draw the operator’s attention to an
undesirable condition. Shutdown alarms are latching. The
fault must be removed and the STOP/RESET button
pressed to reset the module. The icon will be flashing in
the display.
MANUAL MODE
1. Press and release the MANUAL MODE button. The small
LED light next to it should come on.
Note: There is no start delay in this mode of operation.
2. Press and release the green START ENGINE button. The
DSE7310 will send two signals to the engine. The first
signal wire #21 will engage the fuel solenoid, the second
wire, #22, will engage the starter on the engine. At this
point the DSE7310 will start the cranking cycle (10
seconds on and 10 seconds off).
Note: Wire #93 is energized to turn on the glow plugs for
15 seconds first and then the starter and fuel solenoid are
engaged.
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”.
3. During manual operation, the load will not normally be
applied to the generator. But caution must be used, if the
line power should fail or be turned off the transfer switch
during manual operation the load may be applied to the
generator.
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
in the Automatic Transfer Switch. The voltage between
the G1 and the G3 terminals should be the same as it
was on the generator front panel. The voltage should
also be checked between the hot terminals (G1 and G3)
and the G-N to be certain of a balanced voltage output
and a solid neutral connection. The voltage between G1
and G-N should be about 120 volts AC (277 on 480
units). The same approximate voltage should be found
between terminals G3 and G-N (120 volts AC).
On three phase panels the G2 voltage level should also
be checked. 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.
(i.e. if it’s on L-3 on the line side it must be on G-3 on the
generator side.)
CONTROL LAYOUT
STOP/RESET - This button places the module into its Stop/
Reset mode. This will clear any alarm conditions for which
the triggering criteria have been removed. The fuel supply
de-energizes and the engine comes to a standstill. Should a
remote start signal be present while operating in this mode,
a remote start WILL NOT occur.
MANUAL MODE - This button places the module into its
Manual Mode. Once in Manual Mode, the model responds
to the Start button to start the generator and run it off load.
START - Pressing this button from STOP/RESET will start the
engine and run the load.
AUTO MODE - This button places the module into its Auto
Mode. This mode allows the module to control the function
of the generator automatically.
ALARM/LAMP TEST - This button silences the audible alarm
in the controller, de-activates the Audible Alarm output (if
configured) and illuminates all of the LEDs on the module’s
face as a lamp test function.
MENU NAVIGATION - Used for navigating the
instrumentation, event log, and configuration screens.
A small rocker switch is located on the
underside of the engine control cabinet.
On gaseous models, the engine timing is
controlled by the ECU on the engine and you
need to tell it what fuel you want to operate
on; LP or NG.
On diesel models, this switch has been
disconnected and will do nothing.
PROTECTIONS
When an alarm is present, the common alarm LED if
configures will illuminate. The LCD display will show an
icon to indicate the failure.
WARNINGS
Warnings are non-critical alarm conditions and do not
affect the operation of the generator system, they
serve to draw the operator’s attention to an undesirable
condition. Warning alarms are self-resetting when the
fault condition is removed. The icon will appear steady in
the display.

14
OPM-135/D
Also on three phase systems make sure that the rotation
is the same on the generator as it is on your line power.
Failure to insure proper rotation will cause three phase
motors to spin backwards possibly damaging them.
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.
4. 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
To activate the automatic start mode you will just need to
depress the AUTO button, the LED indicator beside the
button confirms that the unit is in automatic mode.
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 to start over.
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.
CONTROL POWER
The DSE7310 controller consumes small amounts of battery
power when it is in use. The controller comes with a power
switch that disconnects battery power when it is not in use.
The switch is designed with a safety relay that prevents it
from removing power to the controller while the generator
is operating. If the switch is turned off while the engine is
running it will continue operating until the engine shuts
down and then the controller will power down.
This switch should be used when the generator is not
going to be used over the course of several days and the
generator is not connected to a battery charger.
A solar charger kit is the easiest way to always maintain the
battery during storage in mobile applications. The supplied
battery charger can be plugged in to an extension cord on
mobile applications.

15 OPM-135/D
OPERATING CONDITIONS
NORMAL OPERATION
This generator-engine set needs load and should not idle
for long periods of time.
If the generator application is for emergency standby the
generator should be exercised at least monthly ideally
under load. Load banking the generator at least annually
will help keep the engine in good condition.
HARSH ENVIRONMENTS
OPERATIONS
Some applications require the generator to operate in
harsh environments. One of the most common hazards are
extremely dusty conditions. In harsh conditions it is often
necessary to take additional steps to keep the equipment
clean and operating at its peak. Maintenance intervals on
lubricant and filter changes may need to be shortened. An
oil quality testing program can also provide early warnings
or oil degradation. Efforts may need to be made to reduce
the amount of dust and debris entering the housing and
generator components.
COLD WEATHER OPERATIONS
The minimum starting temperature with block heater is
-13°F.
The degree of fluidity of the engine oil may be reduced at
low temperatures due to the separation of the paraffin. This
results in the filters becoming clogged.
Oil companies must respect these standards, which provide
for the distribution of fuels adapted to the climatic and
geographical conditions in various countries.
This generator-engine set needs load and should not idle
for long periods of time.
If the generator set will be run in extremely cold
environments it may be beneficial to provide means to
reduce air circulation to increase the temperature of the
enclosure.
Inspect the hoses regularly during cold operation looking
for signs of freezing. If the line freezes it will cause pressure
to build in the crankcase and may cause an engine seal
failure. If the engine operates below optimal temperatures
for long periods of time damage may occur.
