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.

the engine oil and the coolant. Side panels are equipped
with door latches for their removal. All the door latches are
keyed with a common key.
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 qualied, licensed electrician or contractor to
install and wire the transfer switch. The installation must always
comply with all national, state, and local codes.
***** 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 ow.
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 nalizing 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.
These units should be mounted a minimum of 24” from a
structure. This will allow for ample room to maintain and work
on the generator set. Units must be installed in accordance with
all local, state, and national codes. Consult your local agency
having jurisdiction for specic requirements.

4228-0060706-251
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 conict with
any local, state or national codes. If in doubt, always consult
your local re 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 demand
regulator must be four to six ounces per square inch or 7 to 11
inches W.C. (Water column) on 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.
****************
***** WARNING *****
****************
PERSONAL DANGER - Do not use galvanized pipe in fuel line
runs. The galvanized coating can become eroded and ake 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*
PSS60 1.25” pipe NOT
PSS90 1.25” pipe NOT
* Allow an additional 3 feet for each standard elbow.
Do not use ‘street ells’ (restrictive).
** USE THE TWO REGULATOR SYSTEM SHOWN BELOW.
OVER
25 FEET
RECOMMENDED**
RECOMMENDED**
**** 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.
INSTALLING THE FUEL LINE
** NOTICE **
The engine generator sets are properly adjusted before they
leave the factory for a specic 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 eld see information on page 16.
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.
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. Power and performance of the engine
is in direct relation to the correctness of the fuel system. Shown
below is a diagram of a typical L.P. or N.G. installation.
Reference numbers 1 through 3 in the diagrams below are
system parts supplied by customer.
Reference number 4 is the engine generator set.
Below is a table of the fuel pressure reading at each reference in
the system.

Notice the preceding tables give two (2) different units of
measuring fuel pressure. The rst 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.
Remember that whichever fuel delivery system or type of vapor
fuel used, the fuel pressure at the demand regulator installed on
the engine generator must be between 4 and 6 oz. (7-11 inches
of water column). Any lower pressure and the unit will starve
for fuel under load. Any higher and the unit may ‘ood’ when
attempting to start.

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 conrm 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, rell 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 lled 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, rell as specied in the engine manufacturer’s
maintenance instructions. The radiator should be lled to about
1 inch below the ller neck. For additional information on engine
coolant requirements see engine manufacturer’s maintenance
instructions.

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 rst and then
connect the battery negative cable. When removing the
battery cables from the battery reverse the procedure,
disconnect the negative cable rst and then the positive
cable.
5. Be sure all connections are tight and coat the terminals and
cable end with dialectic grease.
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 relling the battery with water use only distilled
water. Tap water will shorten the service life of the battery.
Never ll the battery above the ll line. Over lling above the
upper level line may cause the electrolyte to overow, resulting in
corrosion to the engine or nearby parts. Immediately wash off
any spilled electrolyte following the procedure above.
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
(uid) 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 an Automatic Battery
Charger & Maintainer. This Charger has three rates of charging.
During the rst 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) owing 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. There are
optional 5 and 10 amp chargers available that may be installed
on some units
94228-00
60706-251
** 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 duplex receptacle is mounted on the generator along
side circuit breaker panel, the battery tender is shipped already
plugged into the receptacle.
The engine blockheater installed on this unit should also be
plugged in this receptacle. The block heater is thermostatically
controlled and when plugged in will maintain the engine coolant
temperature between 100 and 120 degrees F.

FOR ALL FIELD WIRING CONNECTIONS TO TERMINALS
OF A CLASS 2 CIRCUIT
INSTALLERS NOTE: To access the AC and DC
interconnections on this unit, open the single door
on the right hand side of the units. Then remove the
safety panel covering the mainline circuit breaker. All
connection are behind this panel.
INSTALLATION NOTES
Because of the many different types of service, feeder, and
distribution equipment, no specic 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, rst
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 specic 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.
A- Neutral Lugs, These neutral lugs are isolated from ground
and provided for you to connect your neutral wire from the
transfer switch to. The lugs on the 90 kW will handle wire sizes
#1 AWG to 600 MCM and should be torqued to 300 in. lbs. The
lugs on the 60 kW will accommodate #4 AWG 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 to the bottom lugs on the circuit
breaker. The generator power feeds have already been wired
into the upper lugs.

****************
***** WARNING *****
****************
A main line 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 operation 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.
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.
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 8 foot copper rod driven into the earth will
provide a proper earth ground.
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 autostart mode and start up the engine generator.
Depending on the distance, 14 to 16 gauge stranded wire should
be used. It is suggested that these wires be labeled S1 and S23.
The terminal blocks are designed to use terminal lugs on all
wires and the screws should be torqued to 9.6 in. lbs.
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.

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.
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 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’.
Use the following check list to verify correct installation before
starting the engine:
Note:Roofaccesspanelshavebeenprovidetocheck/ll
the engine oil and the coolant. Side panels are equipped
with door latches for there removal. All the door latches are
keyed with a common key.
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.

4228-0060706-251
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.

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
conrms 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.

CHANGING THE FUEL TYPE
**** CAUTION ****
EQUIPMENT DAMAGE - Do not make any fuel adjustments
or governor adjustments until all pressure readings are in
compliance with specication. 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.
A small rocker switch has been provide on the underside of the
engine control cabinet (see ref L on Page 13) 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
Advance Power Controller has an idicator light for LP. When this
light is lite the engine is set-up for LP, when the LP light is out the
engine is set up for NG. The ECU will then reprogram the engine
to operate on the proper fuel.

Oil Filter: Both units use PF-35 or PF-454
Engine oil: Use only engine oils displaying the API Certication
Mark “ FOR GASOLINE ENGINES” on the container. Gasoline
engines that are converted for LPG or NG fuels MUST use oils
Coolant System: Check the coolant daily or after each use, and
only when the engine is cool. Maintain the coolant level 3/4 to 1
1/2 inches below the ller neck seat when the coolant is cold.
labeled “FOR GASOLINE ENGINES”. Do not use oils that are
specically formulated for Diesel Engines only. CC or CD classication oils, even when labeled Heavy Duty or for Natural Gas
Engines, ARE NOT ACCEPTABLE.
Multi-viscosity oils are recommended. SAE 10W-30 is recom-
mended for your engine from 0 degrees F (-18 degrees C)
or above. If ambient temperatures are consistently below 0
degrees F. SAE 5W-30 oil can be used Synthetic oils are not
recommended for Industrial or Stationary engine.
Air Filter: Both the PSS60 and the PSS90 use the same air
lter, the IMPCO F1-15.
Spark Plugs: Both units use R42LTS or R44LTS
****************
***** WARNING *****
****************
EQUIPMENT DAMAGE - Never remove the radiator cap when
the engine is hot and never add coolant to any engine that
has become overheated. Either can cause personal injury
and damage to the engine.
The cooling system must be lled with a 50/50 mixture of
antifreeze and water The use of DexCool “Long Life” (typical
orange in color) type coolant is required.
SEE THE ENGINE OPERATORS MANUAL FOR ADDITIONAL
SERVICE INFORMATION
VOLTAGE REGULATOR
The automatic voltage regulator used standard on all models of the PSS60 and PSS90 is the AS440. The regulator is
preset at the factory and should never need adjustment. If you should ever need to adjust the regulator (i.e. you recon-
nect the generator for a different voltage) the only adjustment that should need to be made is the voltage pot. Below is a
description of the AS440, not all function are use on these models. Special order units may use different regulators.
