WARNING:
Do not install or operate the A.C. modular generator system without reading this entire
manual.
The A.C. modular generator system will generate enough voltage to produce a fatal
electrical shock. Do not perform any wiring installations or modifications while the system
is operating. Never touch any live connections while the system is operating. Never
operate the system with the generator wiring enclosure open. Install and secure cover
before operating.
The installation of the Smart Power® A.C. modular generator system is to be done in
accordance with applicable sections in the National Fire Protection Association’s
document NFPA 1901, National Electrical Code
®
, and/or other applicable, recognized
electrical codes and by a certified electrician.
Never directly expose the generator to any liquids, especially water, oil, or solvents.
Electrical shock, fire and/or damage to the generator can occur and will void the system’s
warranty.
Smart Power hydraulic generators, as well as all generators, must be sufficiently protected
from the environment to prevent damage to the stator. Smart Power stators go through a
very important double-dip coating process prior to generator assembly, however, exposure
to direct water sprays can cause the stator to electrically short. Generator damage and
electrical shock can occur.
Caution should be taken during truck pressure washing, since water damage to the
generator can occur if directly sprayed with high water pressure. Though Smart Power
generators are enclosed as much as possible, direct spray through the cooler, fan or open
lid can still cause such damage.
Excessive road spray/salt can also cause an electrical short of the stator in the generator
and can also shorten the generator’s operating life. To prevent this type of damage, do not
mount the system where it will be exposed to road spray.
Evidence of water damage, road spray/salt infiltration, and improper mounting will void the
generator warranty.
Avoid physical contact with any of the components of the A.C. modular generator system
during its operation or immediately after its use. The components of this system will get
hot enough to cause burns and could ignite combustible materials.
Do not mount or locate anything inside of the framework. System overheating could result
and void the system’s warranty.
Smart Power® Systems
A. C. MODULAR GENERATOR SYSTEM
Page 3 of 52
Never operate the system with leaks of any type. Clean up any hydraulic fluid that is
spilled or has leaked out of the system. Hydraulic fluid is combustible, and ignition may
occur.
With the exception of oil filter periodic replacement, never modify or remove any of the
components within the tray assembly.
Never modify or remove any of the components within the pump or the controls mounted
to the pump. This includes all fittings and tubing that are originally provided with the A.C.
modular generator system.
Never make any adjustments to the pump other than for flow control. If it appears the
pump needs to be adjusted, contact Smart Power® Systems at (231) 832-5525 before
proceeding. Damage to the generator from improper pump adjustment will void the
system’s warranty.
Never attempt any adjustments or repairs to the A.C. modular generator system (other
than pump flow control) while the vehicle engine is running and the PTO is engaged.
Never operate the system with the hydraulic fluid exceeding 175F. Above this
temperature, hydraulic fluid can rapidly oxidize and deteriorate causing generator
performance problems. Operating the system while the hydraulic fluid is above 175F will
void the system’s warranty.
Hydraulic fluid is combustible and toxic. In the event of human contact with hydraulic fluid,
generously flush body part (eyes, skin, etc.) with running water. Avoid inhalation of any oil
mist or vapor. Do not ingest hydraulic fluid. In case of fire, use foam, dry chemical or
carbon dioxide to extinguish flame.
Do not exceed the wattage rating of the generator. The generator may be permanently
damaged and the generator and hydraulic components may reach temperatures that could
cause severe burns upon human contact with the components. Operating the generator
system at wattages above the system’s rating will void the system’s warranty.
Disengage the system immediately if a hydraulic fluid leak is detected. Operation of the
A.C. modular generator system with low fluid level will result in permanent damage to the
hydraulic components in the system and will void the system’s warranty.
Do not attempt to operate the generator with the tray assembly top lid open. Do not
tamper with the top lid interlock switch or the hydraulic fluid level sensor.
Never attempt to operate the system without hydraulic fluid. Always maintain a fluid level
between ½ to ¾ full in the sight gage. When installing the system, fill the pump case with
1 pint of hydraulic fluid (Dexron III) before engaging the system. Failing to do so will void
the system’s warranty.

Operating the A.C. modular generator system in the presence of flammable vapors may
result in an explosion.
Use only hoses that meet or exceed the minimum requirements specified in this manual.
A ruptured hose can cause personal injury and/or damage to the generator system.
Do not operate the system under electrical load with air in the hydraulic fluid (the system
will make a growling sound). Do not allow anything to contact the hydraulic hoses that will
cause a kink, pinch or chaffing. The A.C. modular hydraulic system generates hydraulic
pressures approaching 3600 psi. A ruptured hose may result from abrasion, discharging
hot, high-pressure hydraulic fluid, which can cause serious personal injury, fire, and/or
damage to the system.
Never remove the guards on the generator to expose the rotating fan or motor coupling.
Personal injury will result if fingers, hair or loose clothing come in contact with rotating
components.

Description of Product
Hydraulic Generator Applications:
This heavy-duty electronically controlled generator system has been designed to meet the
most demanding mobile applications. It provides 120/240 volt AC @ 60 Hz from no-load to
full load, handling electrical loads of 6200, 8000 and 10000 watts, depending on model.
How our System works:
A generator driven by a hydraulic motor delivers the electrical power. The motor turns at
3600 RPM as controlled by the flow of hydraulic fluid through an electrically controlled
proportional valve. The proportional valve is directly driven by the system controller. The
piston pump delivers fluid to the proportional valve through installer-supplied PTO
mounted to the vehicle’s transmission.
Heat generated in the hydraulic fluid as it passes through the various components in the
system is cooled by a heat exchanger and fan. A filter removes impurities in the fluid. A
venturi boost assembly monitors the volume of oil in the hydraulic circuit and feeds the
system from the reservoir as needed.
Essentially, the only system maintenance required is periodic replacement of the hydraulic
fluid filter and adding hydraulic fluid to maintain the fluid level (when the hydraulic fluid is
between 70 and 80 F, it should be at the ¾ mark on the sight gauge).
Generator hydraulic and electrical schematics: see Figure 1, and Figure 2.

Pre-Installation Guide
Pre-Installation Check List
1. Verify that the Power Take Off (PTO) and the pump rotations match.
To identify the pump rotation, check the pump part number found on the metal tag
attached to side of the pump. A right hand rotating pump (the standard pump
offered by Smart Power® Systems), will have the letter “R” in its part number.
Example: A10VO (45 or 60) DFR-1/52 R PUC.
A left hand rotating pump will have the letter “L” in its part number.
Example: A10VO (45 or 60) DRF-1/52 L PUC.
Depending on genset model, a 45cc or 60cc pump is supplied. To determine the
PTO rotation, check the PTO manufacturer’s specification or observe the PTO when
it is engaged with the vehicle’s engine running.
A right hand rotating pump requires a PTO that turns counter-clockwise when looking
at the free end of the PTO shaft. A left hand rotating pump requires a PTO that turns
clockwise when looking at the free end of the PTO shaft.
WARNING:
Operating the pump with reverse rotation will damage the pump and void the
system’s warranty.
2. Verify that the PTO ratio is properly sized to provide adequate speed to the
hydraulic pump during normal operation of the generator system. The PTO speed
must be between in the range specified in Table 1 for your model generator.
Example: For an ER-8 System that is to operate at 600 RPM:
PTO Ratio = 850 RPM ÷ 600 RPM = 1.42 or 142%
WARNING:
Never exceed the maximum pump shaft speed. Pump failure or premature pump
wear will result. Doing so will void the system’s warranty.
Smart Power® Systems
A. C. MODULAR GENERATOR SYSTEM
Page 12 of 52
3. Verify the combined weight of the pump and hoses filled with hydraulic fluid do not
exceed the PTO manufacturer’s weight restriction. If the pump weight does exceed
this restriction, the installer has two options: A) a bracket to support the pump can
be implemented, or B) the pump can be mounted to the vehicle chassis, connected
to the PTO with a drive shaft.
4. Verify that the pump shaft will mount to the PTO. Pumps supplied by Smart Power®
Systems have an SAE B 2 bolt flange. The standard pumps supplied by Smart
Power® Systems have either a SAE B 7/8” 13 tooth spline for Models ER-6.2, ER-8
and ER-10; OR a SAE B-B 1” 15 tooth spline on the ER-110 model.
Upon special order, a 1” keyed shaft is available on Models ER-6.2, ER-8 and ER-
10. A 1 ¼” keyed shaft is available on the ER-110 Model. Check the PTO
manufacturer’s specification to verify that the pump supplied with the system will
mount to the PTO installed on the vehicle.
Note: In some cases it may be necessary to mount the pump remote from the PTO
and drive it with a drive shaft. Contact the PTO manufacturer for information on the
proper mounting configuration under these conditions.
WARNING:
The installer must provide guarding to prevent damage to the pump seals from road
debris if the pump is remotely located. Also, properly sized and installed vibration
isolators must be used if the pump is mounted to the chassis. Failure to do either
will void the system’s warranty.
Never use an unbalanced drive shaft to drive a remotely located pump. An
unbalanced drive shaft will cause premature wear of the pump and will void the
system’s warranty.
Do not approach a running A.C. modular generator when wearing long, loose items
such as hair, jewelry, ties, clothing, etc. Direct contact with a rotating drive shaft
can cause serious personal injury and/or damage to the system.
5. Obtain the following hoses of the necessary length for the installation:
a) Pump inlet hose: 1” SAE 100R1AT-16 hose (use Parker hose ends P/N 10643-
16-16). Note: Maximum hose length is 20’.
b) Pump outlet hose: 1/2” SAE 100R9AT-8 rated to 4000 PSI (use Parker hose
ends, part number 10643-8-8). Note: Maximum hose length is 20’.
c) Pump case drain hose: 5/8” SAE 100R1AT-10 (use Parker hose ends, part
number 10643-10-10). Note: Maximum hose length is 20’.
Smart Power® Systems
A. C. MODULAR GENERATOR SYSTEM
Page 13 of 52
WARNING:
Do not install hose ends until proper hose length has been determined.
Never install a hose in a location where it will rub against another surface or
abrasion member.
Do not position hoses with tight bend radii. Consult the hose manufacturer’s
installation guidelines. Tight bends may kink and cause serious damage to the
system and will void the system’s warranty.
Use caution when tightening the hose ends to prevent the hose from becoming
twisted.
Never install a 90° fitting at the pump inlet or outlet. Avoid the use of flow
restricting fittings.
Do not form loops in the hose that may collect air or kink. Run hoses as straight as
possible (but not taut) between connections.
Do not exceed hose lengths of 20 feet.
6. SPS models ER-6.2, ER-8, ER-10 and ER- 110 can be mounted on top of a vehicle,
in the open, without requiring any additional coverings. Reference Error!

WARNING:
Do not mount the hydraulic pump or tray assembly in any location that is not well
ventilated. External heat sources elevating the hydraulic fluid and/or the generator
temperature will result in premature wear and degraded system performance and
void the system’s warranty.
7. The tray assembly must be mounted in a position that is higher than the pump. If
the pump inlet hose is 10’ in length or less, the tray and reservoir assemblies must
be a minimum of 12” higher than the pump. If the pump inlet hose is longer than
10’, elevate the tray and reservoir assemblies an additional 12” for every additional
10’ of pump inlet hose length. See below for examples of minimum tray assembly
elevations above the pump:
Pump inlet hose length

8. Locate a p osition to mount the SPS Com mand & Control Cente r. The ideal location
for the Command & Control Center will be in an area that is easily seen and
accessed by the generator operator. When the generator system is in use, the
Command & Control Center will continuously show the status of the generator,
including faults (warnings) if they occur. The Command & Control Center can also
be used to engage and disengage the generator. The Command & Control Center
is water sealed, and operates on low voltages so pump house mounting is
permissible. A 15 ft. water sealed harness is provided to connect the Command &
Control Center to the system controller mounted within the generator tray assembly.
See Figure 5 for the dimensions of the Command & Control Center.

Installation Guide
1. Mount the pump securely to the Power Take-Off (PTO). This may require attaching
a mounting bracket to the PTO housing prior to mounting the pump.
WARNING:
Always mount the hydraulic pump in a position with the pump controls up.
Mounting the pump in any other orientation will not allow hydraulic fluid in the
pump to reach the correct level before starting, causing premature wear of the
pump, thus voiding the system’s warranty. The pump and undercarriage
components will corrode if they are left unprotected. It is advisable to paint them
before completing the installation.
2. Locate and bore mounting holes for generator tray assembly as shown in Figure 6.
Maintain minimum clearances as indicated in Error! Reference source not found.,

WARNING:
Never mount the Generator on its side or upside down. Always mount the generator
upright with its base horizontal. Improper mounting will lead to poor performance
and damage to the system and will void the system’s warranty.
Never operate an AC modular generator system that is not secured in place;
damage will result.
Do not mount the hydraulic pump or tray assembly in any location that is not well
ventilated. External heat sources elevating the hydraulic fluid and/or the generator
temperature will result in premature wear and degraded system performance and
void the system’s warranty.
5. Mount Command & Control Center:
a. Create hole pattern as shown in Figure 8.

6. Flush the hoses with fresh hydraulic fluid (Dexron III). Install hoses and tighten hose
ends, using the Hose Installation Guidelines. See Figure 27 and Figure 31 for
connection locations
WARNING:
Never operate the system with the pump case drain plugged. Damage to the pump
seals will result. To do so will void the system’s warranty.
Lubricate hose fitting o-rings with clean hydraulic fluid (Dexron III) before
installation to prevent damage to them.
Hose Installation Guidelines
Never install a hose without first flushing it with clean hydraulic fluid to remove any
debris.
Never install a hose in a location where it will rub against an abrasive surface or
sharp edge or corner.
Do not position hoses with tight bend radii. Tight bends may kink and cause
serious damage to the system. Consult the hose manufacturer’s guidelines when
installing hoses.
Smart Power® Systems
A. C. MODULAR GENERATOR SYSTEM
Page 19 of 52
Use caution when tightening the hose ends to prevent the hose from becoming
twisted.
Never install a 90° fitting at the pump outlet or inlet.
Never use an inlet line fitting less than 1”.
Never install a hose tightly between connections. Leave length for the hoses to
expand.
Do not form loops in the hose that may collect air or cause kinking. Run hose as
straight as possible (but not taut) between connections.
To keep debris out of hoses while being positioned, cover the ends.
Do not bundle installed hoses tightly together with banding. Hoses must have
freedom to expand.
Do not operate the system with external stresses applied to the hydraulic hoses.
The A.C. modular hydraulic system generates hydraulic pressure approaching 3500
psi. A ruptured hose may result, causing personal injury or damage to the system.
Do not put any substance into the reservoir other than clean, fresh Dexron III
hydraulic fluid. Doing so will void the system’s warranty.
7. Connect the vehicle’s breaker panel to the generator output. The generator is prewired to supply 120/240 VAC, with the generator frame bonded to ground. Route
the generator output conduit/wiring to the breaker panel, and carefully cut the
conduit to length without cutting the wire insulation. A conduit connector has been
provided to connect the conduit to the breaker panel. Connect the (4) four
generator output wires to the breaker panel as follows (see Figure 2 for electrical
schematic and wiring diagram):
Phase A: Black wire (120 VAC)
Phase B: Red wire (120 VAC)
Neutral: White wire
Ground: Green wire
To completely utiliz e the generator’s output capabilities, the 120 VAC loads must be
equally divided between the generator’s two main windings. Before wiring the
vehicle, calculate the wattage of each 120 VAC load that will be connected to the
generator. Next, create two groups of loads based on total wattage (add the
individual wattage of each load together). Exchange loads between the two groups
until the total wattage of the two groups is as close as possible to being equal. Wire
the system with one group connected to Phase A (BLACK) and neutral, with the
other group connected to Phase B (RED) and neutral.
Smart Power® Systems
A. C. MODULAR GENERATOR SYSTEM
Page 20 of 52
ALTERNATE CONFIGURATION: 120 VAC only: If the application requires 120
VAC only, the generator terminal strip should be configured as depicted below. This
method ensures balanced loading of the generator, fully optimizing the system’s
capabilities. Make the following wire connections at the terminal strip:
a) place one jumper between wire 1 and wire 3.
b) place the second jumper between wire 2 and wire 4.
c) connect the phase wire from the breaker box to either wire 1 or wire 3.
d) connect the neutral wire from the breaker box to either wire 2 or wire 4.
e) connect the ground wire from the breaker box to the green wire.
WARNING:
To ensure proper voltage regulation, during the operation of generator system, the
load difference between Phase A and Phase B must never exceed 20%. Damage to
generator system caused by operating it with an unbalance load will void the
system’s warranty.
Wiring of the A.C. modular generator system and electrical distribution throughout
the vehicle must be done in accordance with applicable sections in the National Fire
®
Protection Association’s document NFPA 1901, the National Electrical Code
and/or
other applicable, recognized electrical code and by a certified electrician.
Smart Power® Systems’ A.C. modular generators are supplied with the neutral
bonded to ground. Refer to National Fire Protection Association’s document NFPA
1901, National Electrical Code, and/or other applicable recognized electrical codes
before wiring an SPS A.C. modular generator system.
Never wire any loads to the generator’s output without a circuit breaker in series
with the load. Damage to the generator, to the components within that circuit,
electrical shock, or fire may result if a short occurs in an unprotected circuit. Run
all 120 VAC and 240 VAC electrical connections between the generator and the
distribution panel in conduit. Bypassing the SPS factory installed breaker will void
Smart Power® Systems
A. C. MODULAR GENERATOR SYSTEM
Page 21 of 52
the system’s warranty. Replacement breakers must be obtained from Smart Power®
Systems approved sources only.
Do not perform any wiring installations or modifications while the system is
operating. The A.C. modular generator system will generate enough voltage to
produce a fatal shock.
Never touch any live connections while the system is operating.
Never operate the system with the generator cover removed.
8. Connect 12 VDC (vehicle battery positive) to the generator’s system controller input
(reference Figure 2). Connect the RED wire from the system controller, marked
“Vehicle +12V supply” to the vehicle’s ignition circuit through a 30 amp fuse.
Connect the BLACK wire to the vehicle’s ground (vehicle battery negative).
WARNING:
12 volts DC must be directly applied to the generator system controller whenever
the hydraulic pump is engaged. Failure to do so may cause excessive fluid
temperature, damaging the system components and will void the warranty.
Never come near a running fan with loose items such as long hair, clothing, jewelry,
ties, items that can fall out of pockets, etc.
Do not attempt to operate the generator with the tray assembly top lid open.
Serious personal injury may result if clothing, fingers or other body parts come in
contact with rotating fan blades.
Never operate the system with fan disabled or removed. System over-heating will
result and this will void the system’s warranty.
Improper wiring of the generator system to the vehicle may discharge the vehicle
battery, cause a fire, or cause improper operation of the generator system.
9. Bleed air from the hydraulic system:
a. Turn off the generator’s main power breaker. See Figure 9.
b. Open the case drain hole on the pump by removing the plug (see Figure 31).
c. Fill the Gen-set reservoir with fresh Dexron III hydraulic fluid until the sight
gauge is full. As hydraulic fluid begins to fill the hoses, maintain the level of fluid
in the reservoir until hydraulic fluid begins to flow from the case drain hole on the
pump. Replace the case drain hole plug.
d. Start the vehicle and allow the engine to idle.
e. Ensure the generator purge option is enabled.
Smart Power® Systems
A. C. MODULAR GENERATOR SYSTEM
Page 22 of 52
Note: The generator is shipped from the factory with the purge option enabled.
The system controller has been designed to provide a purge option. With this
option applied, the generator will turn at a reduced speed to minimize wear to
the system’s hydraulic components while purging air from the system. Once
enabled, the purge option will remain set until automatically reset by the system
controller. The system controller will reset the option once the following two
conditions are met:
1. The hydraulic system has been purged for a total of at least 30 minutes.
2. Of those 30 minutes, at least 20 occurred with the generator on.
Main power breaker
Figure 9
WARNING:
Never operate the system without the filler/breather plug installed. Contaminants
may enter the hydraulic fluid through the filler opening, causing premature wear on
the hydraulic components and void the system’s warranty.
Never apply a load to the generator while there is air trapped in the hydraulic fluid.
Damage to the system’s hydraulic components, as well as ruptured hoses, may
result and void the system’s warranty.
Always run the purge cycle after installation, after replacing the hydraulic fluid and
the filter, or after making any other repairs that may allow air into the hydraulic
system. Failure to do so will void the system’s warranty.

within that range, contact Smart Power Systems at (231) 832-5525 for more
information.
10. Prior to applying full load, and after the oil temperature is above 120°F verify proper
operation of the cooler fan by feeling for airflow being pulled into the cooler and
pushed out by the fan. If the air is not being pulled through the cooler face contact
Smart Power® Systems at (231) 832-5525 for more information. Also verify that the
air passing through the cooler and the fan is not restricted.
WARNING:
The SPS Model ER-6.2, ER-8, ER-10 and ER-110 have been pre-set at the factory to
provide correct frequency and voltage. No pump adjustment is required. If it
appears the pump needs to be adjusted, contact Smart Power® Systems at (231)
832-5525 before proceeding. Damage to generator from improper pump adjustment
will void the system’s warranty.
Improper ventilation will result in system overheating, reduced performance and
possible damage to the system and/or cause personal injury. If the system is
installed such that improper ventilation exists, the system’s warranty will be voided.
11. Set “auto-start” option.
If the auto-start option is enabled, the generator will begin generating electricity

Special Operating Instructions
Cold Weather Procedure:
It is strongly recommended that the generator PTO be engaged prior to leaving a heated
garage or fire station in cold weather. The system will generate enough heat to keep its
hydraulic fluid viscosity low enough for proper operation, in all but the most extremes of
low ambient air temperatures.
If the generator system is “started” when the hydraulic oil temperature is below 40F, the
following message will be displayed on the Command & Control Center (reference Figure
23):
Message advising the
oil is cold (less than
40F)

Figure 23
Operating Modes when the system START button is activated (or when the system is in
“autostart”):
When the meter displays hydraulic oil temperatures below 20F, the hydraulic
system will bypass the generator motor and the generator will not produce
power. This mode warms the hydraulic oil.
When the meter displays hydraulic oil temperatures between 20 and 40F, the
generator rotor will turn at a reduced RPM and the generator will not produce
power. This warms the hydraulic oil to 40F.
When the meter displays hydraulic oil temperatures that exceed 40F, the
system will then commence full power generating operations.

Maintenance Instructions
WARNING:
Do not perform maintenance while system is running.
1. Perform regular, periodic checks to verify:
a. The cooler, the cooler fan and generator vents are not plugged by debris.
b. There are no fluid leaks within the framework of the generator, along the hoses,
or at the pump.
c. The hoses are not cut, chaffed, bulged or kinked.
d. That no electrical connections are loose.
e. That the hydraulic fluid level in the reservoir is between ½ to ¾ full in the sight
gage and the hydraulic fluid is clean and bright red in color.
f. That the bolts mounting the pump to the PTO are not loose.
g. If the hydraulic fluid appears dirty or black in the reservoir sight gage, replace
the fluid and filter immediately. Also, if the hydraulic fluid sustains a temperature
over 175° F, replace the fluid immediately. Oxidation can occur naturally over
time and can be accelerated with over temperature operation, affecting
generator output. Always change the filter when the hydraulic fluid is changed.
WARNING:
When adding or replacing hydraulic fluid, always use clean, new Dexron III fluid.
Do not power wash the generator. Doing so will void the system’s warranty.
Do not allow liquid to enter the generator.
If the outside of the generator requires cleaning, wipe surface with a damp cloth.
Clean the Command and Control Center using soap and water with a soft cloth only.
Improper cleaning, handling and use that may scratch, gouge, chip, fade or
otherwise damage the metallic coating and display surfaces are not covered under
the device warranty.
2. Replace the oil filter after every 250 hours of operation, or every three (3) years
(whichever comes first). Use Dexron III fluid and one of the following filters:
Hydac 0080 MA010 P
Puralator 20101

Troubleshooting Guide
Diagnostic:
The Command & Control Center will display certain faults that can assist a service
technician in trouble shooting a problem with the generator system. When these faults
occur, the fault message will periodically flash on the Command & Control Center,
interrupting the normal display. Reference Figure 26 for an example of an over-current
fault.
The faults can also be accessed by repeatedly pressing the mode switch. After displaying
the oil temperature, oil filter time, and configuration, the next display will be the first active
fault. Each time the Mode switch is pressed; the next fault will be displayed. When there
are no more faults to display, the Command & Control Center will return to Normal mode.

Hydraulic Problems:
1. Cavitation:
Cavitation is caused by trying to pump more fluid than is available at the
pump inlet due to system restrictions. Pump cavitation sounds like “marbles”
passing through the pump. Conditions frequently associated with cavitation are the
following:
a. Too many restrictive fittings such as elbows and reducers on the pump inlet
hose.
b. Tight bends or kinks in pump inlet hose and/or tubing.
c. Insufficient tray height above the pump, resulting in low head pressures.
d. Under sized pump inlet hose (minimum pump inlet hose size is 1”).
e. Excessive long inlet hose (may be corrected by using larger hose).
f. Cold hydraulic fluid.
Finding the cause and correcting it should stop cavitation.
Install a 0-25 psig gauge in line between inlet hose fitting and pump inlet port.
Engage PTO. Operate genset with no load for twenty minutes to purge air out of
the system. Observe the pressure reading. The pressure should always be
positive. If the pressure is not positive, system repair/rework is required.
2. Aeration:
Aeration results from air being drawn into the system through leak paths or a
low fluid condition. Aeration makes a “growling” sound and produces visible
bubbles in the fluid stream and/or reservoir. Conditions frequently associated with
aeration are the following:
a. Air leaks in the pump inlet flow path.
b. Low fluid level allowing air to be drawn into the system.
Verify there are no air bubbles in the fluid by viewing inside the reservoir. If there
are air bubbles, check fluid level, tighten all fittings, and look for cracked fittings or
hose leaks on the pump inlet line. Replace any suspect parts and adjust fluid level.
After correcting any problems, again operate the generator twenty minutes to purge
air out of the hydraulic fluid. Note that any bubbles seen in the reservoir indicate
leakage in the pump inlet line.

3. Differential Pressure:
Differential pressure between the inlet pressure and the case pressure over 7
psig causes the piston shoes to lift off the swash plate. This occurs due to the
excessive lower pressure created on the fill (down) stroke of the piston. When the
swash plate begins its upstroke, with pump rotation, it comes back into contact with
the piston shoe, creating chatter.
NOTE: This is NOT NORMAL. The piston shoes should always remain in contact
with the swash plate. The causes of and correction for this problem are the same
as for cavitation above.
With the pressure gauge still installed in the suction line at the pump inlet port,
install a second gauge (0-50 psig pressure gauge) in the case drain line at the
pump case port. Next, engage the PTO and operate the genset with no load for
twenty minutes to purge air out of the fluid. Note both gauge readings. If the
differential pressure at the case is greater than 7 psig, the suction side plumbing will
require evaluation.
Note the following pressure measurements!
Inlet pressures: Should always be positive.
Outlet pressure: Approximately 500 psig with no load on the generator. Note: If
the gauge is fluctuating, record limits.
Case drain pressure to inlet pressure differential: The difference between
pump inlet pressure and case drain pressure should not exceed 7 psig. Pump inlet
pressure minus case drain pressure should never be less than 7 psig.
Verify the installation of the following hydraulic generator hose diameters:
a. Inlet hose (suction) on hydraulic pump (attaches to Port “S” on back of pump): 1
inch
b. Outlet hose (pressure) on hydraulic pump (attaches to Port “B” on back of
pump): 5/8 inch
c. Case drain to hydraulic pump (attaches to Port “L” top side, mid-length of pump):
5/8 inch
Note: The hose diameter appears in print along the length of the hose.
4. System Overheating:
System overheating may be caused by re-circulation of hot air through oil cooler,
dirty or obstructed oil cooler fins, restricted hydraulic fluid flow, excessive generator
load, restricted airflow, previously overheated (old) fluid, non-functional fan, or
improperly adjusted pump.
Smart Power® Systems

Smart Power® Systems
A. C. MODULAR GENERATOR SYSTEM
a. Check the oil cooler fins for debris or damage. Clean and/or replace cooler.
b. Verify that the generator load is not excessive.
c. Verify that there is proper ventilation.
d. Verify that the DC fan motor is operating properly.
e. Verify that warm air from the fan outlet is not being re-circulated through the
cooler.
f. Check the hydraulic fluid to see if it is black or darkened. This indicates
overheating or aging. Drain and flush the system.
g. Fill with new, clean hydraulic fluid.
h. Adjust pump, if necessary, only after contacting Smart Power® Systems at (231)
832-5525.
5. Low Hydraulic Fluid Level In Reservoir:
Low hydraulic fluid level in reservoir can be caused by leaking fittings, hoses or
pipes.
a. Check all the fittings for leaks. Tighten any loose fittings that are found (but do
not over-tighten).
b. Replace defective fittings.
c. Check all tubing for leaks. Repair or replace as necessary.
Electrical Problems
1. No Output Voltage:
a. No output voltage may be caused by excessive current draw opening the circuit
breakers. (The circuit breakers can be found mounted on the generator wiring
enclosure.) Remove all electrical loads from the generator and reset breaker(s).
Re-engage electrical load in increments. If possible, monitor current draw with
the Command & Control Center to determine which portion of the load is
causing the breaker to open.
b. The PTO is faulty. Verify that the drive shaft that links the pump to the hydraulic
pump is spinning when the PTO is engaged. If the shaft is not turning, the
probable cause of the failure is a non-functional PTO. Contact the PTO
manufacture or qualified representative for further information.
c. The generator’s system controller has lost power (reference Figure 2). The
Command & Control Center would stay dark even after the mode and/or on/off
switch is pressed. Verify that the vehicle +12V supply has both +12 volts and
ground. If 12 volts is not available check the vehicle for a blown fuse or a
loose/open electrical connection.

Page 41 of 52
d. The stator field may be shorted or open. With a flashlight, check the generator
windings visible through the ventilation slots. If the windings appear burnt in any
area, the generator must be replaced. If the windings are not burnt, disconnect
wires 1, 2, 3, and 4 from the terminal strip located in the generator wiring
enclosure and make resistance measurement. The resistance between wires 1
and 2, and wires 3 and 4 should be between essentially 0 ohms. Contact Smart
Power® Systems at (231) 832-5525 if any problems are found.
WARNING:
Do not attempt to measure stator field resistance while the system is operating.
Electrical shock may occur.
e. The exciter field may be shorted or open. With a flashlight, check the generator
windings visible through the ventilation slots. If the windings appear burnt in any
area, the generator must be replaced. If the windings are not burnt, disconnect
the exciter field from the field capacitor. Measure the resistance of the exciter
field using an ohmmeter. The resistance of the exciter field should be between
.27 and .29 ohms. Contact Smart Power® Systems at (231) 832-5525 if the
resistance is outside this range.
WARNING:
Do not attempt to measure the exciter field resistance while the system is operating.
Electrical shock may occur.
f. Exciter field capacitor may be faulty. Disconnect the exciter field from the field
capacitor. Using a screwdriver, short leads of capacitor together to discharge
capacitor. Measure capacitance using a capacitance meter. Capacitor should
have capacitance between 47 and 53 microfarads.
WARNING:
Do not attempt to test the field capacitor with the system running. Electrical shock
may occur.
g. The generator drive motor or coupling is faulty. Observe the generator while the
system is engaged. If the coupling is not turning, or if it is turning but the
generator is not, one or more of the coupling components may be damaged and
must be replaced. Also, verify that the coupling halves are mating. If the
coupling halves are not mating, remove the hydraulic motor from the generator
to inspect coupling and the rubber insert between the coupling halves. Replace
components as necessary, reposition and tighten coupling setscrew so both
halves of the coupling are mating correctly.
Smart Power® Systems
A. C. MODULAR GENERATOR SYSTEM
Page 42 of 52
h. The pump is faulty. If no faults are found in steps a. through g., the problem is
likely to be a non-functional pump. Contact Smart Power® Systems at (231)
832-5525 for further instructions.
2. Output voltage exceeds 260 volts or falls below 220 volts AC on a 240 volt
line:
a. Verify that the hydraulic system is not overheating by viewing the temperature
as displayed by the Command & Control Center. The temperature should not
exceed 175° F. If the temperature is greater than 175° F, follow instructions for
system overheating (see hydraulic problems).
b. The hydraulic pump speed may be too low. Verify that the hydraulic pump
speed is in the required range (see Table 1). Pump speed can be calculated by
multiplying the engine RPM by the PTO ratio. Adjust the engine speed or PTO
ratio if necessary.
c. The generator speed may be incorrect. The generator output should be
between 59-61 Hz. If it is not, contact Smart Power® Systems at (231) 832-5525
for further instructions.
d. If the problem is not detected by performing steps a. through c., contact Smart
Power® Systems.
3. Generator Noise:
Generator noise can be caused by defective generator bearings or a faulty
generator/hydraulic motor coupling.
a. Contact Smart Power® Systems if bearings need replacement.
b. Check the generator/hydraulic motor coupling and replace it if necessary.
If problems occur other than those listed call Smart Power® Systems (231) 832-
5525 for additional assistance.

Pump Adjustment
WARNING:
The SPS Electronic Controlled Generators have been pre-set at the factory to
provide correct frequency and voltage, no pump adjustments are required. If it
appears the pump need to be adjusted, contact SPS at (231) 832-5525 before
proceeding. Damage to the generator from improper pump adjustments will void
the system’s warranty.
To prevent permanent, un-repairable damage to the generator, never adjust the
hydraulic pump so the generator’s output frequency exceeds 65 Hz.
Make adjustments to the hydraulic pump flow control with all electrical loads
disconnected from generator.
Never adjust the pump’s pressure control.
Reasons for adjusting the pump:
1. Generated output frequency is “too low.” Verify output frequency when the vehicle
is in fast idle and oil temperature is below 160F. If the frequency drops below
59Hz, the pump output flow may need to be increased.
2. The hydraulic system is running excessively hot: If the system’s oil temperature is
running above 160F with an ambient air temperature of 80F, the pump output flow
may need to be decreased. Before making any adjustment, verify the system is
getting adequate ventilation, that the fans are both operating, the oil cooler air
passageways are not plugged and the hot air exiting the cooler is not being drawn
back through the cooler. Operate system after correcting ventilation problems to
validate whether the system still overheats prior to making pump adjustment.
Note: The generator’s output frequency cannot be decreased by adjusting the
pump flow. If the generator output frequency is too high, contact SPS at (231) 8325525 for further instructions.
Pump adjustment procedure:
1. Enable the generator Pump Set option.
The system controller has been designed to provide a Pump Set option. With this
option applied, the generator will turn at the maximum speed allowed by the hydraulic
pump to allow proper adjustment of the pump’s flow.

Limitation
SPS is not responsible for the repair of generators that is required because of normal
wear, accident, misuse, abuse, improper installation, corrosion, lack of maintenance,
unauthorized modifications, the use of add-on or modified parts, improper storage or
negligence. The warranty is void if the generator is (a) not properly ventilated as
described in the Owners Manual or (b) is exposed (due to improper installation or location)
to water, salt or abrasive particles such as dirt or heavy dust.
The Owners Manual must be completely followed or the Warranty is void.
Normal wear
This warranty will not cover repair where normal use has exhausted the life of a part or
generator. Generators, like all mechanical devices, need periodic parts replacement and
service to perform well. It should be remembered that the service life of any generator is
dependent on the care it receives and the conditions under which it has to operate. Some
applications are very dusty or dirty, which can cause excessive wear when ingested. Such
wear, when caused by dirt, dust or other abrasive material that has entered the generator
because of improper installation/location is not covered by warranty.
