INTRODUCTION
1 INTRODUCTION
1.1 GENERAL
This manual serves as a guideline for the safe and effective
operation, maintenance and possible correction of minor
malfunctions of genverters for marine applications
manufactured and marketed by WhisperPower.
It is therefore essential that every person who works on or with
the genverters should be familiar with the contents of this
manual, and that he/she should carefully follow the instructions
contained herein. Both safety and durability depend very much
on the correct identification, installation and the correct
understanding of ratings, features, design, maintenance and
operation procedures.
The information, specifications, illustrations and statements
contained within this publication are given with our best
intentions and are believed to be correct at the time of going to
press.
All of the specifications, provisions and instructions contained in
this manual apply solely to standard versions of genverters
delivered by WhisperPower.
This manual is valid for the following models:
For other models, see other manuals available on our website:
www.whisperpower.com.
Our policy is one of continued development and we reserve the
right to amend any technical information without prior notice.
Whilst every effort is made to ensure the accuracy of the
particulars contained within this publication neither the
manufacturer nor the distributor or dealer in any circumstances
shall be held liable for any inaccuracy or for the consequences
thereof.
1.2 SERVICE AND MAINTENANCE
Regular service and maintenance should be carried out
according to the directions in this manual. For service and
maintenance, turn to the manufacturer or a dealer.
1.3 GUARANTEE
WhisperPower guarantees that this genverter has been built
according to the principles of good workmanship, according to
the specifications in this manual and according to European
Community safety regulations.
During production and prior to delivery, all of our genverters
are tested and inspected.
This genverter’s correct operation is subject to guarantee. The
period and conditions of this guarantee are laid down in the
general conditions of delivery as registered with the Chamber of
Commerce and Industries for the North of the Netherlands
number 01120025 and are available on request. The guarantee
period is two years, limited to 1000 running hours. Some aspects
of our guarantee scheme are given here in more detail.
Guarantee does not cover failures caused by misuse, neglect or
faulty installation.
Example 1: Faulty installation
Seawater entering the engine is the most common cause of
damage to combustion engines (both propulsion and generator
engines) in boats. The entry of water must be avoided under all
conditions. Be aware that the conditions in blue water sailing can
be extreme. Refer to the installation manual for instructions but
remember these are for guidance only as many factors influence
the installation of the genverter. The ultimate responsibility will
always be with the owner. If in doubt, ask!
Example 2: Misuse
Long term running with no load or too little load can cause the
exhaust to get choked with soot or carbon. Cleaning the exhaust
is not covered by guarantee.
Example 3: Neglect
Sometimes the seal of the raw water pump starts leaking. Mostly
this begins with a little drip and it slowly gets worse. Regular
visual inspection of the genverter is necessary to prevent
damage from occurring due to a leaking water pump. When
serious damage is discovered after weeks of neglect, guarantee
claims will not be honoured.
Example 4: Neglect
A WhisperPower genverter has an option for an auto start/stop
mode or interval mode. WhisperPower cannot be held
responsible for damage caused by the genverter running
unattended. Oil changes must be carried out according to the
maintenance schedule.
Guarantee means that faulty parts are repaired or replaced free
of charge. If necessary the whole genverter unit will be
exchanged. Labour necessary to complete repairs on board a
vessel by an authorized service engineer is covered, but is limited
to a reasonable number of hours and reasonable rates in relation
to the actual repair work that has to be done.
Travel expenses and travel hours are not covered, neither is the
labour required to take a genverter out of a vessel or for
reinstallation. There is no cover for labour needed to get access
to the genverter, for example to remove equipment or parts of
the vessel’s structure or hull.
Goods to be delivered under guarantee will be invoiced. Only
after the faulty goods are returned will the invoice be credited.
Payment in advance may be required or guaranteed by credit
card. If the faulty goods show that the failure was not covered by
guarantee, a credit will not be issued. For example, if a Printed
Circuit Board is returned with clear damage caused by water,
guarantee will be refused.

covered under guarantee. Special services like express mail,
overnight delivery, etc. are not covered. Taxes and duties are not
covered. For shipments to remote areas any additional costs
incurred over normal carriage will be invoiced to the customer.
The cost for returning faulty goods is not covered by guarantee.
If any problem arises which could be subject of guarantee,
procedures should be followed as described in the guarantee
conditions, unauthorized repairs could lead to further damage
and violate the guarantee conditions.
1.4 LIABILITY
WhisperPower does not accept responsibility for damage,
injuries or casualties which are the result of operation of the
genverter in specific conditions bringing dangers which could not
be foreseen, or could be avoided by additional measures.
WhisperPower does not accept liability for damage due to use of
the genverter, possible errors in the manuals and the results
thereof.
1.5 IDENTIFICATION
1.5.1 General
Before using this genverter it is very important to identify the
model correctly. To communicate for service or ordering parts it
is also essential to correctly identify the genverter. For the daily
operation of the genverter it is necessary that the operator
knows the correct specifications as well.
1.5.2 Identification plate
All required identification data are on the identification plate.
The identification plate also mentions some basic features of the
genverter.
SERIAL NUMBER: The identity of the genverter is given by the
serial number. Using this number, the manufacturer can trace
the specifications of the genverter.
POWER: The identification plate gives the maximum load in kW,
i.e. kVA calculated with power factor one. When calculating a
load one should always take into account the power factor or cos
phi of this load. The resulting load should not exceed the nominal
power as shown on the identification plate. Power is rated at an
ambient temperature of 25°C. For higher temperatures the
genverter has to be de-rated.
Piccolo 2/8, 3/10/12, 3+/15 — March 2020 — EN 5
INTRODUCTION
VOLTAGE: The Permanent Magnet Alternator (PMA) generates a
variable voltage between 250V and 400V. Depending on the type
of installation, this is converted by a DC PowerCube or an AC
Power Module for Genverter
FREQUENCY: The Permanent Magnet Alternator output
frequency is considerably higher than in in common alternating
current installation. The DC PowerCube and WP-PMG (Power
Module for Genverter), however, are designed to generate very
stable DC and AC outputs from the PMA output.
CURRENT: The maximum allowed current at the specified
voltage and power factor.
PHASE: The number of live wires running from the genverter.
WEIGHT: The net dry weight (approximately) in kg. This is
without fuel, oil, cooling liquid, packaging and external
installation equipment.
CE-MARKING: The “CE” symbol shows that the genverter is built
according to European Community safety regulations. This
includes the regulations regarding safety of pleasure craft,
electric safety and electric magnetic compatibility (EMC) and
other relevant directives. Under the Machinery Directive, the
genverter is an incomplete machine and can only comply after
installation; refer to the Declaration included in this manual.
Safety is also a matter of installation, utilization and operating
conditions. See also 2.1.
It is recommended to consult the manufacturer before changing
a factory setting. If the genverter involved is not new, former
users may have changed the settings. Check the settings when
there is any doubt.

GENERAL INFORMATION
Nevertheless take note of the triangular signs on
the genverter indicating danger.
Fuels can be flammable. Proper handling limits the
risk of fire and explosion.
WARNING
Never use the genverter in situations where there
is danger of gas or dust explosion or where
potentially flammable products are present!
When lifting the genverter avoid any risk of
personal injuries. In particular, do not stand under
the genverter.
2.1.6 Operation
WhisperPower genverters have no external moving parts like
fans and V-belts. The fan of the radiator unit is covered by a grid.
The hot parts of the engine are covered by the sound shield and
therefore these genverters are very safe when the sound shield
is closed.
• The genverter should be operated by authorized personnel
only.
• Be aware of hot parts and especially parts of the exhaust
system and the cooling system.
• If the genverter is unsafe, fit danger notices and disconnect
the battery positive (+) lead so that it cannot be started until
the condition is corrected.
• Do not attempt to operate the genverter with a known
unsafe condition. Disconnect the battery positive (+) lead
prior to attempting any repairs or cleaning inside the
enclosure.
• Always consult the manual before carrying out
maintenance.
• Do not change the settings without consulting the
manufacturer. Keep a record of setting changes in this
manual.
2.1.7 Fire and explosion
2.1.8 Dangerous substances
Fuels, oils, coolants, and battery electrolyte can be hazardous to
personnel if not handled properly. Do not swallow or have skin
contact with these liquids. Do not wear clothing that has been
contaminated by fuel or lubricating oil.
The gaskets used in the genverter are free of asbestos. However,
gaskets containing asbestos can still be found. Avoid inhaling
particles of this material as this may result in fatal diseases.
Therefore it is a good habit to be careful with gaskets.
On no account allow unprotected skin to come into contact with
the injector spray as the fuel may enter the blood stream with
fatal results.
Engines may be fitted with seals or O-rings manufactured from
"Viton" or similar material. When exposed to abnormally high
temperatures in excess of 315°C an extremely corrosive acid is
produced which cannot be removed from the skin. If signs of
decomposition of the material are evident, or if in doubt, always
wear heavy duty disposable gloves.
2.1.9 Warning regarding life support applications
The WhisperPower genverters are not intended to be used as a
component of any life support system unless a specific written
agreement pertaining to such intended use is executed between
the manufacturer and WhisperPower. Such agreement will
require the medical equipment manufacturer either to contract
additional reliability testing of the genverter and/or to commit
to undertake such testing as a part of the manufacturing process.
In addition the medical equipment manufacturer must agree to
indemnify and not hold WhisperPower responsible for any claims
arising from the use of the genverter in the life support
equipment.
• Avoid refilling the fuel tank while the engine is running.
When oil or fuel is leaking do not use the genverter.
• Hydrogen gas generated by charging batteries is explosive.
Ensure proper ventilation. Do not smoke and do not allow
sparks, flames, or other sources of ignition around
batteries.
• Keep a fire extinguisher on hand.
• In case of fire, do not open the sound shield. To avoid
serious injury or death from fire, shut down engines,
generator sets and blowers. However, if you do open the
sound shield, immediately discharge the entire contents of
a portable fire extinguisher into the enclosure.
• Poor electrical connections or using wiring which is not
suited for the rated currents can cause overheating and
possibly fire.
Piccolo 2/8, 3/10/12, 3+/15 — March 2020 — EN 7
2.2 TRANSPORT, LIFTING AND STORAGE
• Use soft slings to avoid damage
• The engine has a lifting eye which can be used to take the
genverter out of the enclosure. It can also be used to lift the
complete genverter including the enclosure.
• After transporting the genverter check for damage before
installation.
• Long term storage can have detrimental effects on engine
and alternator. The engine should undergo an engine
preservation procedure (refer to the maintenance chapter.)
• Condensation may occur on alternator windings. To
minimize condensation, store the genverter in a dry and
warm storage area.
• While the battery is stored it should be recharged every 12
weeks.

GENERAL INFORMATION
2.3 FEATURES
2.3.1 General
The WhisperPower genverters combine carefully selected
engines with highly efficient Permanent Magnet alternators. The
voltages and frequencies produced, however, require the
genverter to be connected to a WhisperPower DC PowerCube or
Power Module producing clean DC or AC output. This is an
original concept, which is cost-effective as wells as easy on
installation.
2.3.2 Construction
The genverter incorporates a diesel engine which has a
permanent magnet alternator in the flywheel. The engine is
mounted on a steel base frame and mounted securely on a
double set of anti-vibration mounting pads in a sound attenuated
enclosure. The output of the power from the alternator will be
between 300V-400Hz and 400V-500Hz, depending on the engine
speed. The engine speed is set to strike a balance between fuel
efficiency and comfort. All cables and hoses are guided through
the enclosure’s sides.
2.3.3 Control
The genverter’s control system is based on microprocessor
technology. On models featuring Digital Diesel Control (DDC),
several operating modes and automatic start/stop functions can
be programmed and monitored (refer to Digital Diesel Control
user’s manual).
All functions can be set from the remote control panel, which
comes as standard with the genverter, including an RJ12
connecting cable.
2.3.4 Installation
The genverter is not self-contained and is only operable after
proper installation using additional accessories and installation
materials such as a starter battery, fuel supply and an exhaust
system.
Installation accessories are listed in the installation manual and
are available through the supplier of the genverter.
2.3.5 Documentation
Included in the delivery are:
• This user’s manual (no. 40200421)
• An installation manual (no. 40200701)
• A DDC operating manual (no. 40200801), as applicable
• A DDC quick reference guide (no. 40200142), as applicable
The user’s manual contains a list of important maintenance and
spare parts as well as a chapter on maintenance and problem
solving. Manuals in other languages are available on request.

TECHNICAL INFORMATION
WARNING
The alternator magnets are very powerful.
Prevent drilling chips or metal parts from entering
into the sound shield as these may be drawn into
the alternator and cause the alternator to fail.
WARNING
The alternator’s magnetic field may cause false
compass readings. This should be taken into
account when installing a compass.
3 TECHNICAL INFORMATION
3.1 EXPLANATION OF FUNCTIONAL PARTS
WhisperPower genverters are highly advanced systems. They
combine new technologies from various fields such as engine
technology, PM alternator technology and, in the PowerCubes
and Power Modules, inverter technology.
3.1.1 Control system
The standard electrical engine control system is 12 Volt negative
earth. Non-earth return (ungrounded) is available as option.
Check your identification data to determine which system is
being used. Either system is of the "energize to run" type: it stops
when the 12 V DC voltage is taken away.
3.1.2 AC Permanent Magnet Alternator
The Three Phase Permanent Magnet Alternator is incorporated
in the flywheel and has a very high efficiency of at least 94%. The
output of the power from the alternator will be between 250V300Hz and 400V-500Hz, depending on the engine speed. As the
efficiency is very high, little cooling is needed. The alternator and
the engine use the same cooling system.
3.1.3 Engine
The genverter has a Kubota engine fine-tuned by WhisperPower.
The engine has indirect injection and was designed to meet the
highest emission standards. The cooling system can be used for
CHP (Combined Heat and Power production). Contact
WhisperPower for additional information.
Further details are in the data sheet in 3.2.
3.1.4 Starter battery charging
The engine is equipped with a 12.5A (Piccolo 8) or 40A
(Piccolo 10) alternator for charging the starter battery. The
voltage is regulated at ±14.4V.
3.1.5 Piccolo PMG control
WP-PMG POWER MODULE GENVERTER (PICCOLO 8)
Through the WP-PMG Power Module Genverter, the user can
control and operate the genverter.
By pushing the START button on the PMG control panel (refer to
Figure 5) for two seconds, the control system is activated and will
start the engine automatically. Pushing the STOP button (again
hold two seconds) will stop the engine and the electrical system
will be deactivated.
Piccolo 2/8, 3/10/12, 3+/15 — March 2020 — EN 13
Figure 5: WP-PMG control panel (230V model shown)
The various control panels indicate the AC load. As far as PMG
operation and functionality is concerned, the reader is referred
to the PMG User’s Manual.
3.1.6 Piccolo DDC and Piccolo 10, 12 and 15 control
3.1.6.1 Alarms and shut-down
In the event of malfunctioning this will be indicated by the failure
light, details will be shown on the display and the engine will be
shut down. Three parameters are being monitored: oil pressure,
oil temperature and exhaust temperature.
Exhaust temperature too high indicates that the injection of
cooling water into the exhaust is being blocked .
All alarm switches are closed when no malfunction occurs. A
contact is cut in the event of an alarm. This means that the
genverter will not work when the alarm switches are broken or
when there is a loose wire. The system therefore is intrinsically
safe. The panel will display details about the alarm.
3.1.6.2 Control
The genverter can be operated by push buttons on the panel on
the unit or on the remote control. Pushing the START button will
activate the control system and will start the engine
automatically. Pushing the STOP button will stop the engine and
the electrical system will be deactivated. When using the
genverter in an automatic mode the engine will start when
power is demanded, e.g. because of low batteries or another
“event” that triggers the starting operation. Various automatic
modes are available through the remote control panel. Refer to
the DDC Operating manual for more information.

TECHNICAL INFORMATION
3.1.6.3 Remote control panel
The remote control panel is used to make the various settings. It
also displays parameters such as Voltage, Hz, Amps, and many
others (refer to the DDC manual for details).
The connection between the remote control panel and the
genverter control unit is made using plug-in connectors. A 10 m
communication cable is in the standard supply. If necessary, a
longer or shorter cable can be supplied. Multiple remote control
units can be put in parallel by using the connectors on the back
of the units (refer to installation instructions).
Diesel pre-heater
Optionally, a diesel pre-heater can be installed. This is a useful in
extremely cold conditions. In this case the fuel filter will be inside
the enclosure and there will be a heating element upstream of
the filter preventing the formation of paraffin crystals in the
diesel and clogged filters as a result. The system’s operation is
temperature-dependent and is controlled by a separate switch
to turn it “on” or “off”.
3.1.8 Biodiesel
The use of diesel fuels to a maximum blend of 5% (by volume) of
Fatty Acid Methyl Esters (FAME) known on the market as B5
diesels is allowed as far as these fuels comply with EN 14214
(Europe) or ASTM D-6751 (USA), as appropriate.
Biofuels should be supplied by recognized and authorized
suppliers only. ”Self-blended fuels” may cause engine damage
and will affect warranty.
Please note that free methanol in FAME may result in corrosion
of aluminium parts. Free water in FAME may result in choked fuel
filters and injectors and may result in increased bacterial growth.
3.1.9 Lubricating oil
1 Specification:
The oil must be suitable for oil changes as specified in the
maintenance chapter. The engine must be run on heavy duty
lubricating oil meeting the requirements of API class CF, CF-4,
CH-4, CI-4 or CI-4 plus . It is recommended to use lubricating oil
from WhisperPower or a well-known brand.
3.1.7 Fuel Specification
The engine must only be used with diesel fuel oil conforming to
the standards for use in modern diesel engines. It is essential that
the fuel should be free from water and contaminants. The
following specifications must be complied with:
14 Piccolo 2/8, 3/10/12, 3+/15 — June 2020 — EN
2 Oil viscosity:
We recommend 10W40 multi grade oil. In very cold or hot
conditions, a special grade could be applied according to the
Viscosity Chart below:
Page 15

Piccolo 2/8
2.1 L
Piccolo 3/10/12
3.2 L
Piccolo 3+/15
4.0 L
Do not overfill with lubricating oil as this may have
a detrimental effect on engine performance.
3 Oil capacity:
The content of the crankcase and oil filter, is as specified below
(approximate data):
TECHNICAL INFORMATION
4 Lubricating oil pressure:
• Minimum at idle: 49 kPa (0,5 kgf/cm2 - 7psi).
• Normal at 3000 rpm: between 147 and 490 kPa (1,5 up to
5 kgf/cm2 - 21 up to 71 psi).
• Minimum at 3000 rpm: 98 kPa (1,0 kgf/cm2 - 14 psi).
3.1.10 Cooling liquid
The genverter is cooled by cooling liquid. Use only long-life type
G12+ cooling liquid in order to minimize maintenance. The
capacity of the engine’s cooling system is approximately 3.5
litres. When the cooling is based on keel cooling or radiator
cooling the capacity of these coolers and piping has to be taken
into account.
Initially, the engine can be filled via the filling cap on the exhaust
manifold. Fill up till the level is just below the filling cap. Filling of
the alternator cooling system and additional filling of engine
cooling system has to be done via the expansion tank. When the
engine is on temperature the liquid will expand and the
redundant liquid will be pressed into the expansion tank. This
tank has to be filled up till the mark.

OPERATION
4 OPERATION
4.1 GENERAL
The genverter is operational after full installation and filling up
with fuel, engine lubricating oil and cooling liquid, connecting the
battery and connecting the digital remote control panel, if
applicable.
4.2 PROGRAMMABLE SPEED
At the time of commissioning, the engine rpm are set to meet
the output requirements of the installation.
4.3 CONTROL PANELS
The genverter is usually operated either from the PMG control
panel (Piccolo 8) or from the DDC remote control panel.
4.4 OPERATING INSTRUCTIONS
4.4.1 Daily check of oil level
Be sure to keep the oil level between upper and lower limits of
the oil gauge. Too much oil may cause a drop in output or
excessive blow-by gas, while too little oil may seize the engine's
rotating and sliding parts.
Procedure:
1 Check the engine oil level before starting or more than 5
minutes after stopping the engine.
2 Remove the oil dipstick, wipe it clean and reinsert it.
Take the dipstick out again, check the oil level gauge and
reinsert the dipstick.
18 Piccolo 2/8, 3/10/12, 3+/15 — June 2020 — EN
3 If the oil level is too low, remove the oil filler plug, and add
new oil to the prescribed level.
4 After adding oil, allow the oil to come down to the oil pan
before checking the oil level again.
4.4.2 Summarized operating instructions (daily use)
Routine "pre-start" checks:
1 Check oil level and cooling liquid level.
2 Water inlet (all valves open).
3 For systems incorporating PMG: power source selector
switch (off/shore power/generator power) in “off” position,
or switch of all consumers in the usual way. If a Whisper
Switch of Transfer System Switch is installed, this operates
automatically.
4 Switch on battery switch (if installed).
5 Fuel valve: open.
Starting:
Push the start button and hold for one (DDC) or two (PMG)
seconds to initiate the fully automatic starting procedure.
In operation checks:
1 Check for abnormal noise or vibration
2 Check the output parameters on the remote control display
3 Check sea water flow at exhaust outlet
Page 19
OPERATION
Never use ether or gasoline to facilitate a cold
start as it could damage the engine.
Neither remove the battery while the engine is
running nor remove any electrical cable while the
battery is connected to the circuit. Only
disconnect the battery with the engine stopped
and all switches in "OFF" position.
4 For systems incorporating PMG: switch power source
selector to “generator” position. If a Whisper Switch of
Transfer System Switch is installed, this operates
automatically.
5 Before loading the generating set up to its maximum, have
it run warm. Continuous load should be restricted to 70 %
of maximum load.
Stopping the genverter:
1 If the genverter has been running under full load for a
longer period, do not shut it down abruptly. Reduce the
electrical load to about 30% of the rated load and let it run
for around 5 min.
2 Press the STOP button and hold for one (DDC) or two (PMG)
seconds.
3 Close the inlet sea water valve.
4 Switch to another AC power source, if available.
4.4.3 Extended operating instructions
Check when starting the first time or after a longer period of rest:
1 If there is any damage caused by transport or installation.
2 Check if the installation conforms to the installation
instructions.
3 Ensure the engine is free to turn without obstruction.
4 Check all hoses and hose connections for leaks.
5 Check all cables and terminal connections.
Routine "pre-start" checks:
1 Check engine oil level. The genverter switches off in the
event of insufficient oil pressure. Even when the oil level is
too low, the oil pressure can be high enough not to trip an
alarm. Do not run the engine with the oil below the lowest
mark, because a smaller volume of oil will become
contaminated considerably quicker than a larger volume.
Moreover, a low level may affect cooling. Therefore, we
recommend daily oil-checks. Check oil level prior to starting
the engine or at least 5 minutes after the engine has
stopped.
2 Check for leakages.
3 Switch off all devices.
4 Switch on the battery switch (if installed).
Starting the genverter:
By pushing the start button and holding it for one (DDC) or
two (PMG) seconds, the electric system is activated. You can
monitor the procedure on the display of the remote control
panel. First, the fuel pump will prime the fuel for a few
seconds (settable); the starter will then crank the engine
until it starts. While starting the alarms are blocked (this is
Piccolo 2/8, 3/10/12, 3+/15 — March 2020 — EN 19
achieved by pushing the Start button). The alarms are
reactivated after 10 seconds.
Warm up the engine without load for 3 minutes. A restart
protection prevents cranking the engine when it is already
running, which could cause damage.
Checks once the engine is in operation:
1 Check for abnormal noise or vibration.
2 Check the output parameters on the remote control display.
3 Observe the exhaust at the rated load.
The exhaust must be free from soot. Do not allow the
engine to run with visible smoke from the exhaust without
investigating the cause, as this may result in an expensive
breakdown.
Engine load during longer operation:
During the first 50 hours of running, the continuous load
should be restricted to 70 % of the maximum load. Running
at no load or light load for long periods in the first 50 hours
may cause cylinder glazing and high oil consumption.
Avoid overloading the genverter. Overloading occurs when
the electrical load (demand) is so high that by the diesel
engine has trouble driving the alternator. It causes the
engine to run rough, while using oil and excessive fuel and
producing soot. The engine may even stop. The genverter
should therefore be loaded at the maximum rated power
for short periods (2-3 hours) only! The high peak current is
meant for the ability to start electrical devices that need a
high current for starting especially electric motors and
compressors (from a still stand state).
In order to prolong the genverter’s life expectancy, the
nominal electrical demand of the system should not exceed
70% or the genverter’s rated maximum load. Please note
this when switching on your electrical equipment!
Nevertheless, the genverter is designed so as not to
overheat, even under extreme conditions.
Do not run the genverter for very long periods at no load or
at very low load. When this is necessary, increase the load
to at least 70% for one hour in 10 hours. Long term running
at too low load will cause the exhaust to be choked by
carbon (soot).
Page 20
If the engine is not running and the ‘failure’ and
‘charging’ LEDs are blinking, press the stop
button in order to prevent the starter battery
from being drained.
OPERATION
Stopping the genverter:
1 Avoid stopping the genverter abruptly after a long period of
operation at high load. Prior to switching off the genverter,
decrease the load (i.e. turn off most electrical consumers)
and let the genverter run at low load for approx. 5 minutes
to allow the engine to cool down sufficiently. Another
reason to switch off electrical consumers prior to stopping
the genverter is the voltage drop that occurs as the engine
comes to a halt.
If the genverter is operating in a hot environment and is not
allowed to cool down, excessive heat in the engine may trip
the "high temperature" alarms. This will prevent restarting
of the engine for some time.
2 Press the STOP button for one (DDC) or two (PMG) seconds.
3 Switch to another 230V power source, if available.

MAINTENANCE
5.2 ALTERNATOR
The alternator does not require maintenance.
5.3 ENGINE
5.3.1 Preliminary instructions
The first service on the engine should be carried out after 50
running hours. This period also applies after a major overhaul.
During the first 50 hours, the engine should receive special
attention:
• Long periods of light or no load running in the first 50 hours
may lead to cylinder glazing and high oil consumption.
• For the same reason it is of the greatest importance to use
the right oil specification.
Piccolo 2/8, 3/10/12, 3+/15 — March 2020 — EN 21
5.3.2 Bleeding the fuel lines
When the engine is started up for the first time or after it has run
out of fuel, the fuel system may need to be primed. Push the start
button activating the electric system and activating the fuel
pump. When more time is needed to bleed, hold the “Start/Stop”
button on the local control panel (so not on the remote panel).
While the button is held, the pump will work, but the unit will
not start. Hold as long as necessary to bleed the system
5.4 REGULAR MAINTENANCE
5.4.1 General precautions
All regular maintenance can be carried out when the enclosure
is open. When oil and dirt have gathered in the enclosure,
measures have to be taken to prevent oil from being spilled.

MAINTENANCE
• Be sure to conduct daily checks, periodic maintenance,
refuelling or cleaning on a level surface with the engine shut
off and the control system fuse removed.
• Do not touch muffler or exhaust pipes while they are hot;
Severe burns could result.
• Allow the engine to cool down sufficiently, especially before
changing the oil or the oil filter cartridge. Oil can be hot and
cause burns.
• Contact with engine oil can damage your skin. Put on gloves
when using engine oil. If you come in contact with engine
oil, wash it off immediately.
• When changing engine oil, dispose it according to local
regulations.
• When cleaning any parts, do not use gasoline but use
regular cleanser.
• Always use proper tools, that are in good condition. Make
sure you understand how to use them, before performing
any service work.
• Be sure to tighten all bolts lest they should be loose. Tighten
the bolts by the specified torque.
• Do not put any tools on the battery, or battery terminals
may short out. Severe burns or fire could result. Detach the
battery from the engine before maintenance.
5.4.2 Servicing after break-in
• Change engine oil and replace the oil filter (refer to 5.4.3).
• Check and tighten nuts, bolts, and unions, paying particular
attention to the fuel system and using the torque chart
below.
3 Put some tissues under the oil filter cartridge.
4 Remove the old cartridge with a filter wrench.
5 Apply a film of oil to the gasket for the new cartridge.
6 Screw in the cartridge by hand. When the gasket contacts
the seal surface, tighten the cartridge not too firmly, by
hand.
7 Remove the oil filler cap on top of the engine, refill the
engine with oil (refer to 3.1.9 for specifications and
quantity). Allow the oil to come down to the oil pan and
check the oil level.
8 The oil level should be as close as possible to the maximum
level. Add (or drain) oil as necessary.
NOTE: When the genverter runs less than 200 hours a year, the
oil should be changed yearly.
5.4.4 Checking the battery
• Check battery terminals for corrosion
• Check the battery acid level (not applicable when sealed
batteries are used).
5.4.5 Adjusting the V-belt tension
Before adjusting belt tension, inspect the belt for glazing, cracks,
or dryness. A worn or damaged belt should be replaced.
1 Apply moderate thumb pressure to the belt between the
pulleys. When the belt is pressed in the middle of the span,
the deflection should be between 7 mm and 9 mm.
2 If the tension is incorrect, loosen the alternator mounting
bolts and, using a lever placed between the alternator and
the engine block, pull the alternator out until the deflection
of the belt falls within acceptable limits, then tighten the
alternator mounting bolts.
• Observe the exhaust at the normal full load. The exhaust
must be free from soot. Do not allow the engine to run with
a dirty exhaust without investigating the cause as this may
result in an expensive breakdown. When ramping up RPM
the engine will probably produce some smoke. After
stabilizing on the right RPM for the load the exhaust should
be free from soot.
• Check the electrical connections.
5.4.3 Changing engine oil and oil filter cartridge
1 Run the engine until it is on temperature, stop it and let it
cool down sufficiently to allow safe working.
2 Drain oil through the dipstick hole using a vacuum pump as
commonly used in garages.

MAINTENANCE
When handling fuel, make sure there are no open
flames or other fire hazards near the engine. Wipe
off any spilled fuel completely. Spilled fuel can
ignite and cause fire.

Figure 14: Pump housing: bolts to be unscrewed
Figure 15: Fuel filter (similar on all models)
5.4.6 Draining water from the fuel tank
If fuel gets mixed with particles of foreign matter such as dust,
dirt, or water, it can cause not only a decrease of output but also
malfunctions of the fuel system. To avoid such problems, drain
fuel tank as described below.
1. Position an oil pan (capacity of 2 litres or more) under the
drain cock of fuel tank.
2. Open the drain cock of fuel tank and drain at least 1 or 2
litres of fuel.
3. Make sure that all water and particles of foreign matter are
discharged with the fuel. Close the drain cock.
running. Before changing the filter, clamp off the supply line. The
arrow on the filter housings indicates the flow direction. Remove
the hoses from the old filter and fit the new filter.
5.4.9 Changing the air filter element
The genverter is standard supplied with an air inlet filter
element. Filter change depends on air quality.
Procedure:
1. Unscrew the cover in order to gain access to the filter.
2. Clean the foam around the element with compressed air
and clean the strainer element.
3. Check the air filter and replace it when necessary (do not
clean the air filter element).
4. Put back the cover and retighten the screws.
5.4.7 Replacing the raw water pump impeller
Both the impeller and the gasket between the pump case and
the cover should be replaced. So when ordering the impeller,
order a gasket, too (see Section 7, Spare parts). Remove the
cover to get access to the impeller. Remove the old impeller with
the help of two screwdrivers. Install the new impeller and add
some grease. Turn the blades in the direction of rotation of the
pump i.e. anti-clockwise looking at the impeller.
On M-GV 8 Piccolo genverters, the pump housing needs to be
taken from the engine in order to gain access to the cover. This
is achieved by removing the bolts shown in Figure 14. Remount
the pump after changing the impeller.
5.4.8 Replacing the fuel filter
Filter change depends on the level of contamination of the fuel,
but should be done at least every 400 running hours. A clogged
filter results in a lack of output of the engine and irregular
Piccolo 2/8, 3/10/12, 3+/15 — March 2020 — EN 23
5.4.10 Checking hoses and electrical connections
Visually check cooling hoses, fuel hoses and electrical wiring,
paying particular attention to abrasion, wear and corrosion.
Have items replaced when necessary.
5.4.11 Servicing after 800 hours and beyond
This includes the items described above, but also procedures
requiring a professional diesel mechanic. Contact your
WhisperPower Service Centre. Please find some essential data
for Kubota-based genverters below:
‒ Valve clearance: from 0.145 mm to 0.185 mm when the
engine is cold.
‒ Rocker arm bracket nut M6 × 1: from 9.81 nm to 11.2 Nm
‒ Cylinder head screw M8 × 1.25: from 38 Nm to 42 Nm.
5.5 PUTTING OUT OF SERVICE
When not using the genverter for a longer period it is
recommended to perform an engine preservation procedure.
1. Clean the engine.
2. Loosen the fuel suction pipe and fuel return and put them
in a can with preservation diesel fuel.
3. Run the engine until it is on temperature, stop it and let it
cool down sufficiently to allow safe working.
4. Drain the hot engine oil and refill with preservation oil.
5. Disconnect the battery and store it in a dry place free of
frost and charge it regularly.
6. Close inlet and outlet openings with tape.
7. Protect the genverter against the influences of bad weather
conditions.
This method of preservation will be sufficient for 6 months.
Change oil before using the engine again.

TROUBLESHOOTING
6 TROUBLESHOOTING
6.1 GENERAL
If any problem should occur, check basic conditions and examine
all external wiring, switch gear and circuit breakers. Also check if
measuring instruments give the correct value. If in doubt,
measure directly on the alternator terminals with an
independent instrument.
6.1.1 Piccolo 8
In case of inverter failure or oil pressure, oil temperature or
exhaust temperature limit exceeding, the error will be indicated
on the PMG local panel (bottom left; refer to Figure 9).
6.1.2 Piccolo DDC version
6.1.2.1 General
If during the measurements mentioned in 6.1 the engine
immediately stops after starting and an error code is displayed
at the remote control panel ( “AC VOLTAGE”), the genverter can
be restarted by means of a “service start” in the service menu
(see “service start” in the user’s manual of the Digital Diesel
Control). Started this way, the genverter will keep running for 2
minutes before it stops. This offers you the possibility to carry
out measurements to investigate the cause of the failure. This
procedure should only be carried out by an experienced
electrician.
6.1.2.2 Failure codes
A failure code is displayed when a failure at the genverter is
detected. A warning code is displayed when a parameter
deviates from the setting.

6.2 ALTERNATOR/ ELECTRICAL FAULTS
Beware of parts which are live! The alternator
generates voltage up to 650 V.
Remove 3 A fuse from the control panel while
working on the genverter in order to prevent the
engine from starting.
PROBLEM
CAUSE
SOLUTION
No output (voltage) at all
• Circuit breaker "off" or faulty fuse
Check switches and fuses and measure directly on
the alternator to exclude external causes.
• Low engine RPM
Check the engine RPM and adjust (refer to special
procedures)
• Alternator failure
Check alternator resistance (1.4Ω). Contact
WhisperPower Service
Genverter output voltage too low
and RPM above 2500 while running
without load
• Alternator failure
Contact WhisperPower Service
Genverter output voltage too low
under load, but OK in no load
condition
• Genverter is overloaded
Switch off a load; reduce number of consumers
• Insufficient engine RPM
Increase minimum RPM setting
• Engine RPM drops when loaded
Refer to “Engine speed drops” section in 6.2
Remove 3 A fuse from the control panel while
working on the genverter in order to prevent the
engine from starting.
When the engine is not cranking well, starting problems almost
always originate from battery problems or poor battery cable
connections.
When the engine does crank, starting problems almost always
originate from lack of fuel or air bubbles in the fuel pipes.
A failure code is displayed when a hardware failure at the engine
is detected.
PROBLEM
CAUSE
SOLUTION
Diesel engine fails to crank; no
response at all
• Faulty fuse on the control panel
Replace fuse
• Battery switch off
Switch on
• Battery completely empty
Charge or replace battery
Diesel engine fails to crank, the
starter makes clicking noises, or the
engine cranks very slowly.
• Almost certainly this is a battery problem.
DDC display, if present, will indicate “LOW
BAT1”
Check battery voltage. Recharge the battery.
Inspect battery terminals and cables for a good
electrical connection (inspect for corrosion,
tattered wires, etc.)

PROBLEM
CAUSE
SOLUTION
• Wiring system faulty
During the normal starting process, the battery
voltage drops to 11V (with a fully charged battery).
If the voltage does not drop during starting, the
electrical connection is faulty. If the battery voltage
drops lower than 11V, then the battery has been
discharged too deep.

Engine exhaust smokes
• Faint blue smoke - generally the result of
light load
Increase load.
• Heavy blue smoke - caused by lubricating
oil: oil level too high, worn cylinder,
stuck, broken or worn piston rings.
Check the oil level
Check the compression
• When the engine RPM is ramping up to
react at a load step some smoke may be
unavoidable.
No action required.
• Wrong setting of minimum RPM.
