INTRODUCTION AND
DESCRIPTION
With the addition of an Automatic Transfer Switch this packaged
standby system includes all items necessary for a completely
automatic standby power system.
DESCRIPTION
This package power system is designed to automatically provide
standby power to unattended loads during electrical outages.
Upon an interruption of normal electrical service this package
power system's electrical control circuits will automatically start
the engine. The generator will produce electrical power and the
Automatic Transfer Switch (A.T.S.) will automatically transfer the
electrical loads to the engine-generator set. Upon restoration of
normal electrical service the A.T.S. will sense return of the normal
commercial power and retransfer the load back to normal
commercial power source. The engine control circuits shut off the
run signal to the engine generator set.

INSTALLATION
****************
***** WARNING *****
****************
PERSONAL INJURY - Before proceeding with the installation, be
sure the operation selector switch is in the "stop" position.
General Information
Note: Roof access panels have been provide to check/fill the
engine oil and the coolant. Side panels may be removed by
removing the thumb screws on the bottom under side of
each panel
These engine generator sets are for outdoor installation. These
units must be bolted solidly to a concrete pad. The transfer
switch is mounted next to your distribution panel inside the
building. Consult a qualified, licensed electrician or contractor to
install and wire the transfer switch. The installation must always
comply with all national, state, and local codes.
These units should be mounted to allow for ample working room
around it. Units must be installed in accordance with all local,
state and national codes. Consult your local agency having
jurisdiction for specific requirements.
FUEL INSTALLATION
The fuel supply should be as close as possible to the engine.
This will reduce the installation cost of fuel runs. 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 gas supplier.
****************
***** WARNING *****
****************
FIRE HAZARD - All fuel runs should be installed by a licensed
fuel supplier.
Connect the fuel supply to the inlet of the fuel solenoid (see table
for recommended line size). The pressure at the secondary
demand regulator must be four to six ounces psi (per square
inch) or 7 to 11 inches W.C. (Water column) for vapor withdrawal
units. On units equipped with liquid withdrawal fuel systems full
tank pressure is plumbed to the fuellock strainer mounted on the
generator rails. The fuel converter mounted on the unit will
handle both vaporization of the fuel and pressure reduction.
INSTALLING THE FUEL LINE
***** CAUTION *****
EQUIPMENT DAMAGE - These units must be mounted on a
solid concrete pad to prevent air from exiting under the unit.
Allowing air to exit under the unit may cause the unit to overheat
from lack of proper air flow.
Before beginning the installation process recheck the rating of the
generator set and its transfer switch rating. Be certain they can
handle the intended load and are compatible with the entrance
voltage, phase and current ratings. 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. For full service switching the
A.T.S. must have a fusible disconnect (circuit breaker) installed
before the switch to protect the contacts.
ENGINE GENERATOR SET MOUNTING
The unit’s main frame should be bolted solidly to a 4 to 6 inch
thick cement pad. The engine-generator is mounted on a subframe which is attached with special shock mounts to the main
frame. This allows the engine-generator free movement without
affecting the control panel which is mounted on the main frame.
Do not shock mount the main frame. Engine vibration will be
transmitted to the control panel causing erroneous start/stop
cycles and premature control failure.
** NOTICE **
The engine generator sets are properly adjusted before they
leave the factory for a specific fuel, either NG (natural gas), LP
(liquid propane vapor) or LPG (liquid withdrawal propane). This
fuel type is noted in your model number. If it becomes necessary
to change the fuel type in the field see information on page 13.
Line Size (vapor system)
Unit location will determine the size of fuel line that is required to
supply the engine with a constant fuel pressure. Refer to the
tables below for fuel line size, fuel consumption and recommended tank size. For distances of 25 feet and over, a two
regulator fuel system is recommended. This is accomplished by
installing a primary regulator at the tank which will reduce the
tank pressure down to 10 to 15 lbs. A secondary regulator is
installed to further reduce the fuel pressure to the required six (6)
oz operating pressure. This secondary regulator must be at least
10 feet from the engine generator set. Any closer installation will
require a larger line be installed to provide a fuel reservoir. If this
is not done, the demand regulator on the unit and the pressure
regulator in the fuel line will interfere with each other. When this
two (2) stage regulator system is used, a fuel line size of 3/4 to 1
inch is generally adequate for distances up to 300 feet from the
primary to the secondary regulator. (Consult your local fuel
supplier for your exact requirements). The appropriate line size
from the table below is then installed from the secondary regulator to the generator set.

****************
***** WARNING *****
****************
PERSONAL DANGER - Do not use galvanized pipe in fuel line
runs. The galvanized coating can become eroded and flake off,
causing possible obstructions in the regulator or fuel valve. The
results could range from inoperative engine start to hazardous
fuel leaks.
Size of pipe normally required for generators operating on NG/LP:
up to 25 feet* over 25 feet*
PSS30 1" pipe not recommended
PSS40 1" pipe use a two regulator system
* Allow an additional 3 feet for each standard elbow.
Do not use ‘street ells’ (restrictive).
**** CAUTION ****
EQUIPMENT DAMAGE - Be careful when sealing gas line joints.
Excessive sealing compound can be drawn into the solenoid,
regulator or carburetor causing an engine malfunction.
FUEL PRESSURE (vapor system)
Correct fuel pressure cannot be stressed enough. The most
common cause for inoperative systems is an inadequate or
incorrect fuel pressure. Performance of the engine is in direct
relation to the correctness of the fuel system. Shown below is a
block diagram of a typical L.P. or N.G. Installation.

Notice the preceding tables give two (2) different units of measuring fuel pressure. The first is with a pressure gauge calibrated in
ounces per square inch. The second and most accurate is the
use of a simple water manometer. A manometer is calibrated in
inches of water column.
LP LIQUID WITHDRAWAL SYSTEMS
When installing a unit equipped the LP liquid withdrawal a
primary regulator is not required on the supply tank. The supply
line is connected to a liquid withdrawal valve on the supply tank
and runs directly to the fuellock strainer mounted on the engine
generator set. Normally a 3/8 to 1/2 inch copper line is acceptable for this type of fuel installation. You must be sure that the
valve you have connected to on the supply tank is in fact a liquid
supply valve and has a drop tube inside the tank that is pulling
fuel from the bottom of the supply tank. Before starting the unit
you must confirm that you have a good liquid supply at the unit.
Engine generator sets equipped for liquid withdrawal will not
run properly when supplied with high pressure vapor fuel.
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.
COOLANT
Before starting the engine, check the coolant level in 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 selector switch remains in the “stop” position. This should be
your last step before initial start-up.
A customer supplied twelve-volt 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. Gel batteries should not be used with the battery
tender installed in the generator enclosure.

Installation and servicing of batteries must be performed or
supervised only by personnel knowledgeable of batteries and the
required precautions. Keep unauthorized personnel away from
batteries.
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
tion.
not work for this applica-
ately with water and seek immediate medical attention.
* Spilled electrolyte is to be washed down with an acid neutral
izing 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
* Never smoke when near batteries.
* Do not cause a flame or spark in the battery area.
* Always discharge static electricity from your body before
touching batteries by first touching a grounded 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. When refilling the battery with water use only distilled
water. Tap water will shorten the service life of the battery.
Never fill the battery above the fill line. Over filling above the
upper level line may cause the electrolyte to overflow, resulting in
corrosion to the engine or nearby parts. Immediately wash off
any spilled electrolyte following the procedure above.
CAUTION – PERSONAL DANGER
CAUTION - NEVER dispose of a battery in a fire. The battery is
capable of exploding.
CAUTION - 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.
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 cable first and then the positive
cable.
5. Be sure all connections are tight and coat the terminals and
cable end with dialectic grease.
WARNING – The electrolyte is a diluted sulfuric acid that is
harmful to the skin and eyes. It is electrically conductive and
corrosive. The following precautions must always be taken.
* Always wear full eye protection and protective clothing.
* Where electrolyte contacts the skin, wash off immediately
with water.
* If electrolyte contacts the eyes, flush thoroughly and immedi
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. Check the electrolyte
(fluid) in the battery periodically to be sure it is above the plates.
Never allow the battery to remain in a discharged condition.
CONNECTING THE BATTERY CHARGER &
BLOCKHEATER
A three-stage battery charger is provided standard for all 12 volt
standby systems. The standard charger is a Automatic Battery
Charger & Maintainer. This Charger has three rates of charging.
During the first stage, know as BULK Charging, the charging
current is limited to 2 Amps at a voltage of up to 14.5 volts. The
green LED will blink during this stage. During stage two, know as
ABSORPTION Charging, the charging voltage is held at 14.5
volts and the charging rate gradually reduces the amount of
current (amps) flowing to the battery. The green LED will also
blink during this stage. Stage three is called MAINTENANCE
Charging. During this stage the voltage will drop to 13.3 volts and
the charge rate will drop to as low at .1 amps. This keeps your
batteries in a fully charged condition without over charging them.
During this stage the green LED is constantly lit
** NOTICE **
The trickle charger is not intended to recharge a battery which
has become completely discharged. It is designed to produce
just enough current to maintain a fully charged battery.
The battery tender receptacle is to be powered by a GFCI circuit
and installed in accordance with the United States National
Electric Code. These AC wires can be run in the same conduit as
the other AC leads from the generator. It is suggested that this
circuit be fused for 15 amps, then both the battery charger and
the block heater can be connected to the same circuit. A 120 volt

***** WARNING *****
****************
FIRE HAZARD - All wiring must be done by a licensed electrician, and must conform to the national electrical code and comply
with all state and local codes and regulations. Check with the
local authorities before proceeding!
INSTALLATION NOTES
Because of the 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 A.T.S. Control and safety systems
will eliminate all paths for feedback.
To wire the automatic transfer switch into the existing wiring, first
determine which circuits will be on the emergency load circuit. If
the entire load is to be transferred, the transfer switch can be
wired in directly after the watt-hour meter and the service entrance, providing the service entrance ampere rating is within the
transfer switch’s rated capability.
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
A.T.S. 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.

***** 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.
The load current carrying wires (L) and (T) must be sized to
handle the maximum load current without excessive voltage drop.
By code, the wire must be heavy enough to handle the full current
rating of the main line circuit-breaker (or fuse) in the entrance (or
sub-panel) protecting the contactor switch.
A - Customer Remote Start CONNECTIONS TERMINALS. The
two remote start leads from the Automatic Transfer Switch are
connected to the two terminals marked 1 & 23. The wire in
terminal labeled #1 is Battery Negative and the wire in the
terminal labeled #23 is your Remote Start lead. Closing these two
leads together will signal the DSE 7310 to go into an auto-start
mode and start up the engine generator.
All wires should be installed in rigid or flexible conduit. (Knockouts are provided in the control box).
See the manual shipped with the Automatic Transfer Switch for
connection locations in the switch. Connections in each switch
will vary depending on the type of switch and the manufacturer.
GROUNDING
A grounding lug has been provided on the engine generator set
to grounded to earth ground if required. Check with your local
codes. Generally a 6 foot copper rod driven into the earth will
provide a proper earth ground.

INITIAL START UP
****************
***** WARNING *****
****************
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.
Use the following check list to verify correct installation before
starting the engine:
Note: Roof access panels have been provided to check/fill
the engine oil and the coolant. Side panels may be removed
by removing the thumb screws on the bottom under side of
each panel.
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. All engine functions are controlled by the ECU on the engine.
The ECU on the engine will send information signals to the
DSE7310 via the CAN connections to indicate oil pressure, water
temperature, etc for the display on the engine control.
All shutdown functions are also controlled by the ECU on the
engine, what you see displayed on the DSE7310 display is what
is happening inside the ECU on the engine.
The AC output readings displayed on the DSE7310 are collected
through the AC interface harness wired in the generator control
box. An shutdowns related to the AC output are not a function of
the engine ECU but are based on information collected in the
DSE7310 via this AC harness.
1. Engine oil. Fill as required with proper grade/qty.
2. Engine coolant. Fill as required with proper
mixture.
3. Unit mounting base properly bolted down.
4. Clearance for service and maintenance on all
sides.
5. Proper fuel line material and size.
6. All fuel line connections tight.
7. Fuel line protected and a moisture trap installed
(may be required for N.G.).
8. Correct LP/NG pressure 4-6 Oz. (7-11" Wc).
9. Battery connections clean and tight.
10. Battery fully charged.
11. All AC and DC wiring installed and properly
protected.
After completing the above checklist, the engine-generator set is
ready for the initial start-up test.
STARTING PROCEDURE
MANUAL MODE
****************
***** WARNING *****
****************
EQUIPMENT DAMAGE - BEFORE ATTEMPTING TO START
THIS UNIT COMPLETE YOUR PRESTART CHECKLIST AND
INSURE 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.
1. Depress the manual mode button on the control panel. The
small LED light next to it should come on.
2. Press the start button- The DSE7310 will send a start signal to
the ECU on the engine. The engine ECU will then energize the
fuel solenoid and 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
4. 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 to 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.
** 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.
5. 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 start mode.

To test the automatic start Transfer Switches follow the instruction
in the operator’s manual you received with your transfer switch. If
you get a fault light during the initial start up or prior to start up it
is most likely a false warning light. Simply reset the ATS and
start over.
Once you have completed testing of the ATS, be sure you
ALWAYS leave the system in standby mode unless servicing the
unit. For standby operation, press the AUTO button on the front of
the engine control. The green light should light up next the AUTO

CHANGING THE FUEL TYPE
**** CAUTION ****
EQUIPMENT DAMAGE - Do not make any fuel adjustments or
governor adjustments until all pressure readings are in compliance with specification. See fuel pressure charts (tables 1, 2,
and 3).
These engine/generator sets are very easy to convert between
LP or NG. As the engine timing is controlled by the ECU on the
engine you only need to tell it what fuel you want to operate on.
In the customer connection box there is a fuel selection terminal.
A small rocker switch has been provide on the underside of the
engine control cabinet (see ref L on Page 9) for this purpose.
Opening the rocker switch will tell the ECU mounted on the
engine that you are operating on NG Fuel. Closing the rocker
switch will tell the ECU that the fuel being supplied is LP. The
ECU will then reprogram the engine to operate on the proper fuel.
