whichever occurs first. Warrantee does not cover failures
that are caused by misuse, neglect or a faulty installation.
December 2010 / M-SC6/8/10 / EN
INTRODUCTION
Example 1. Faulty installation:
Seawater entering the engine is the most common cause
of damage to combustion engines in boats. (Both to
propulsion and generator engines.) 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 a generator. The ultimate responsibility will
always be with the owner to ensure a safe and compliant
installation. If in doubt ask!
DAMAGE CAUSED BY THE INGRESS OF
WATER IS NEVER COVERED BY
WARRANTEE
Printed Circuit Board is returned with clear damage
caused by seawater, guarantee will be refused.
Freight costs to deliver spares by normal mail or carriers is
covered under guarantee. Special services like express
mail, overnight delivery etc. are not covered. Taxes and
duties are not covered. For shipments to remote off shore
areas any additional costs incurred over normal carriage
will be invoiced to the customer.
The cost for returning faulty goods is not covered under
guarantee.
If any problem arises which could be subject of guarantee,
procedures should be followed as described in the
guarantee certificate, unauthorised repairs could lead to
further damage and violate the guarantee conditions.
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 warrantee.
Example 3: Neglect
Sometimes the seal of the raw water pump starts leaking.
Mostly this begins with a little drip and slowly gets worse.
Regular visual inspection of the generator is necessary to
prevent damage to occur from a leaking water pump.
When one find serious damage after weeks of neglect
warrantee claims will not be honoured.
Example 4: Neglect
Whisper generators have an option for an auto start/stop
mode or interval mode.
WhisperPower cannot be held responsible for damage
caused by the unattended running generator.
Guarantee means that faulty parts are repaired or
replaced free of charge. If necessary the whole generator
unit will be exchanged. Labour necessary to complete
repairs on board a vessel executed 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. Also
not covered is the labour required to take a generator out
of a boat or for reinstallation. There is no cover for labour
needed to get access to the generator, for example to
remove equipment or bulkheads etc.
Should work take place, which is not in
accordance with the guidelines, instructions
and specifications contained in this user’s
manual and the supplementary installation
manual, then damage may occur and the
generating set may not fulfil its specifications.
In all these cases the guarantee may become
invalid. Use original spareparts only!
1.4
LIABILITY
WhisperPower does not accept responsibility for damage,
injuries or casualties which are the result of operation of
the generating set in specific conditions which brings
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 generator, possible
errors in the manuals and the results thereof.
Automatic start/stop
WhisperPower cannot be held responsible for damage
caused by the unattended running generator using the
auto-start/stop mode or interval mode.
Goods to be delivered under warrantee 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 after the faulty goods are
returned, it is indicated that the failure was not covered by
guarantee a credit will not be issued. For example if a

identification plate are also some basic features of the
set:
IDENTIFICATION
1.5.1
General
Before using this generating set it is very important to
identify the set correctly. To communicate for service or
ordering parts it is also essential to correctly identify the
generating set. Also for the daily operation of the generating set it is necessary that the operator knows the correct
specifications.
1.5.2
2
POWER
The identification plate gives the nominal maximum
continues load in kVA (= kW) 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 power should never exceed the
nominal power as shown on the identification plate.
Power is rated at an ambient temperature of 40°C and
a seawater temperature of 25ºC. For higher
temperatures the generating set has to be derated.
3
VOLTAGE shows the nominal voltage.
This voltage should be within the specified tolerance
at the nominal frequency.
4
FREQUENCY is shown in Hz and is determined by
the speed of the engine (RPM). 50 Hz correlates with
3000 rpm, 60 Hz correlates with 3600 rpm.
5
CURRENT shows the maximum current that is
acceptable at the specified frequency, voltage and
power factor.
6
WEIGHT shows the net dry weight (approximately) in
kg. This is without fuel, oil, packing and external
installation equipment
7
The CE symbol shows that the generating set is build
according to European Community safety regulations.
This includes the regulations regarding the safety of
pleasure craft, machinery, electric safety and electric
magnetic compatibility (EMC) and other relevant
directives.
Identification plate
All required identification data are on the identification
plate. For location of the identification plate see figure 1.
Safety also relies on the installation, application and
circumstances. See also the remarks in this manual under
SAFETY.
Figure 1: Location identification plate

The identity of the generating set is given by the
SERIAL NUMBER.
When this number is available the manufacturer can
trace the specifications of the generating set. On the
Before changing a factory setting you are advised to
consult the manufacturer. When the generating set you
have to identify is not new you have to take into account
the possibility that former users may have changed the
settings. Check the settings (voltage, frequency, rpm)
when there is any doubt.

INFORMATION
2 INFORMATION
2.1
SAFETY
2.1.1
General
When correctly installed and used in normal
circumstances this generating set fulfils EC safety
regulations. This generating set could be part of an
installation or could be used in a way that additional
regulations of the EC or other authorities have to be taken
into account.
Circumstances could make it also necessary
to take additional measures. Be aware of wet
conditions and hazardous environments
caused by explosive gases etc
2.1.2
Electrical safety
The voltage of 230 Volt generated by this
generating set is dangerous and if instructions
and procedures are not strictly observed may
result in electrical shock which will result in
severe personal injury or loss of life.
•
•
Check all wiring at least once a year. Defects,
such as loose connections, burned cables etc.
must be repaired immediately.
2.1.3
Be aware that insulation protection systems can be
different for different applications and even within the ship
there could be different standards for different spaces. We
did refer to the Recreational Craft Directive that applies to
pleasure craft up to 24 m of length. Sometimes one has to
comply with other standards such as the rules of
certification societies like Lloyds Register of Shipping or
Veritas, regulations for the protection of personal, building
legislation, etc. It is of the greatest importance to have
expert advice on this issue.
In all situations the transfer switches between
shore, inverter and generator should switch
both neutral and L1. Of course this is the case
when using a Masterswitch.
Do not work on the electrical system if it is still
connected to a current source. Only allow
changes in your electrical system to be carried
out by qualified electricians.
2.1.4
•
Connection and protection must be done in
accordance with local standards.
•
Using the auto-start/stop (interval) mode the
generator can start unexpectedly. When
working on the electrical system, the 3 Amp
fuse must be removed from the control panel
and the battery plus cable must be removed
from the battery.
Warning signs indicate parts which could be
live.
EN / M-SC6/8/10 / December 2010
Earth insulation failures
According to local regulations and depending on the
application it could be necessary to take measures for
protection against earth insulation failures.
In the standard delivery “neutral” and “ground” are not
connected. To make a connection between “neutral” and
“ground” could be necessary as part of a specific
insulation failure protection system.
Small pleasure craft in Europe is submitted to The
Recreational Craft Directive 94/25/EC. The guidelines of
this directive refer to (ISO 13297).
When the installation complies with this standard the
“neutral” and “ground” should be connected on the
generating set.
Installation
Whisper generating sets are not self-contained and have
to be properly installed in enclosed areas such as a
machine room.
Installation includes measures to be taken to
outlet exhaust fumes which contain carbon
monoxide and are extremely dangerous.
Carbon monoxide (CO) is an invisible odourless gas.
Inhalation produces headache, nausea or death.
Installation includes measures for proper ventilation, safe
electric connections, safe installation of the starting
battery, proper fitting of the cooling system and fuel pipes
etc. Refer to the installation manual.

INFORMATION
2.1.5
Operation
2.1.6
External moving parts like fans and V-belts are covered by
the canopy and therefore the Whispers are very safe when
the canopy is closed.
8
Fuels can be flammable. Proper handling
limits the risk of fire and explosion.
Nevertheless take note of the signs on the
generating set which show symbols in a
triangle indicating danger.
•
Avoid refilling the fuel tank while the engine is
running. When oil or fuel is leaking do not use the
generating set.
When service has to be carried out while the
engine is running, be aware of moving parts
like V-belts.
•
Do not run the engine close to explosives or
gasses.
•
Hydrogen gas generated by charging batteries is
explosive. Ensure for proper ventilation. Do not
smoke or allow sparks, flames, or other sources
of ignition around batteries.
•
Keep a fire extinguisher on hand.
•
Poor electrical connections or using wiring which
is not suited for the rated currents can cause
overheating and possibly fire.
•
The generating set should be operated by
authorised personnel only.
•
Be aware of hot parts and especially parts of the
exhaust system and the cooling system.
•
If the generating set is unsafe, fit danger notices
and disconnect the battery positive (+) lead so
that it cannot be started until the condition is
corrected.
•
Fire and explosion
Do not attempt to operate the generating set 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
Chemicals
•
Fuels, oils, coolants, and battery electrolyte can
be hazardous to personnel if not treated properly.
Do not swallow or have skin contact with these
liquids. Do not wear clothing that has been
contaminated by fuel or lubricating oil.
•
Gaskets may be manufactured from asbestos.
Particles of this material should not be inhaled as
this may result in fatal diseases.
•
On no account allow any 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 abnormal high temperatures in
excess of 400°C an extremely corrosive acid is
produced which cannot be removed from the
skin. If signs of decomposition are evident, or if in
doubt, always wear disposable heavy duty
gloves.

2.2
TRANSPORT, LIFTING AND STORAGE
When lifting the generating set avoid any risk
of personal injuries, do not stand un-der the
generating set..
•
Use soft slings to avoid damage
•
On the engine are two lifting eyes, only to be
used to take the generator out of the capsule. Do
not use to lift the set including the capsule and
certainly not including the steel foundation plate !
•
After transporting the generating set check for
damage before installation.
•
Long term storage can have detrimental effects
on engine and alternator. The engine should be
put through an engine preservation procedure.
(Refer to the maintenance chapter).
•
The alternator windings tend to condense. To
minimise condensation, store the generating set
in a dry and warm storage area.
•
After removing the generating set from long term
storage perform an insulation check. (Refer to the
alternator
maintenance
paragraph
for
procedures)

Engine
The M-SC6 and 8 generating set is based on the
Mitsubishi L2E 2 cylinder diesel engine. The M-SC10 on
the L3E 3 cylinder. The engine is indirectly injected. The
engine is oil cooled and the oil is cooled by a heat
exchanger and raw water. The heat exchanger and all
other parts which are in direct contact with the raw (sea)
water are made of seawater resistant material like naval
brass and gunmetal.
The engine has been specially adapted for the
WhisperPower application and is very different from the
standard engine supplied for industrial applications!

AC alternator
The single phase alternator is directly coupled, one
bearing, brushless, rotating field design, two poles (3000
RPM) and self-regulating.
Residual magnetism causes a small voltage over the
stator windings and allows a current to flow in the
windings, which is magnified because of the feedback
effect between rotor and stator. The field windings in the
rotor are short-circuited over a diode to rectify the current.
A capacitor over an additional winding in the stator which
is at an angle with the power-winding keeps the voltage
stable within 5 % at the specified rpm and provides voltage
fall off with speed, preventing over-excitation at low engine
speeds and softening the effect of load switching to relieve
the burden on the engine. The M-SC8 and 10 can be
equipped with an optional voltage regulator to keep the
voltage tolerance within 2%.
Further technical data on the design of the alternator can
be found in drawings and diagrams in this manual.

TECHNICAL INFORMATION
Digital Diesel Control system
The standard electrical engine control system is 12 Volt
negative earth, non-earth return (ungrounded) is available
as optional. Check your identification data to determine
which system is applied. The system is designed
according to the "energise to run" system. The Digital
Diesel Control is a very advanced microprocessor based
full automatic system. Besides automatic start the system
offers many monitoring options. Refer to the separate
Digital Diesel Control user manual.
The microprocessor unit is located on top of the alternator.
13
INFORMATION
2.5.4
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 CD, CF or CF_4.
Battery charger
On the engine is an alternator generating 40 Amp 12V.
This current is rectified to charge the battery. The voltage
is regulated at ±14.4V.
2.5.5
2.5.6
It is very important to use the correct oil
specification. Very often local oil suppliers
recommend a higher class, because they
assume that a higher class is allowed. This is
not the case. One should not follow these
recommendations.
Using the wrong specification will cause high
oil consumption.
Alarms and shut down
In the event of malfunctioning this will be indicated by the
failure light and details will be shown on the display the
engine will be shut down. There are three functions
guarded: oil pressure, oil temperature and exhaust
temperature.
Exhaust temperature too high indicates the cooling water
to be blocked.
All alarm switches are closed when no malfunction occur.
A contact is cut in the event of an alarm. This means that
the generating set will not work when the alarm switches
are broken or there is a loose wire. The system therefore
is intrinsically safe. The panel will display details about the
alarm.
2
Oil viscosity:
We recommend a multigrade oil 15W40.
3
Oil capacity:
Excluding the oil filter the content of the crankcase of
the M-SC6/8 is 2.4 l; M-SC10: 3,6 l. Including the oil
filter it is 2.9 l; M-SC10: 4,1 l. Note that the engine
may contain some residual oil due to testing at the
factory.
While filling, check the lubricating oil level by means
of the engine oil dipstick. Do not overfill with
lubricating oil as this may have a detrimental effect on
engine performance.
Control
The generating set can be operated by push buttons on
the panel on the alternator or by the remote control. By
pushing the START button the control system is activated
and will start the engine automatically. Pushing the STOP
button will stop the engine and the electrical system will be
deactivated.
2.5.7
Remote control
All wiring connections from the remote control to the board
are made by plug in connectors.
An intermediate communication cable is in the standard
supply. If necessary an optional longer 8 wire cable can be
connected if the standard length does not suit the required
distance. Numerous remote control units can be put in
parallel by using the connectors on the back of the units.
(Refer to installation instructions)
2.5.8
Hour counter
The remote control offers several timer functions that help
to schedule maintenance.
2.5.9
Load indicator
On the remote control the load will be indicated on the
display and by the LED-bar. The load is measured by a
current transformer on the alternator.

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/cm 2 - 14
psi).
2.5.12 Cooling liquid
The engine is cooled by cooling liquid. The capacity of this
system of the M-SC6-8 is 2 litres and of the M-SC10 3,5
litres.
Always use coolant which is compatible with
aluminum components of the cooling system.
Do not mix coolants with different kinds of
chemical compound, as this may cause
congelation of the coolant. In case of doubt
refresh the content of the entire cooling
system.
2.5.10 Fuel specification
The engine must only be used with diesel fuel oil which
conforms to the standards for use in modern diesel
engines. Fuel free from water and contaminants is of the
utmost importance.
2.5.11 Oil information

Specification:
We recommend not using water but cooling liquid that is
marketed for the use in combustion engines. Cooling liquid
protects the engine against frost to minus 25° C. Also it
protects the engine block against corrosion. One can fill
the engine via the filling cap on the exhaust manifold. Fill
up till the level is just below the filling cap. When the
engine is on temperature the liquid will expand and the
December 2010 / M-SC6/8/10 / EN
INFORMATION
redundant liquid will be pressed into the expansion tank.
This tank has to be filled up till the mark. When cooling
liquid is not available clean fresh water could be used with
an additive of anti-freeze. When using water with antifreeze the right mixture has to be calculated according to
the information of the supplier of the anti-freeze. When the
cooling is based on keel cooling or radiator cooling the
capacity of these coolers and piping has to be taken into
account calculating the right mixture. The cooling liquid in
the engine is pressurised and has a boiling point above
100° C. The temperature switch in the thermostat housing
switches at 110° C. When keel cooling or radiator cooling
is applied the cooling system is not pressurised. There
should be a special cap on the manifold without valves
leaving the connection to the expansion tank open. Refer
to the manual on keel cooling and radiator cooling.

DIAGRAM ELECTRONIC GOVERNOR
The M-SC8 and 10 3000 rpm are equipped with an
electronic governor in addition to the mechanical governor
that is on other Whisper models. A governor keeps the
speed (RPM=Rotations Per Minute) of the engine at a
fixed value. The RPM of the engine correlates with the
frequency of the electrical output (3000 RPM =50 Hz) of
the alternator.
Under full load the RPM of the Whisper models that has
only a mechanical governor can drop 75 RPM (=2.5 Hz) at
full load and will go further down or collapse when further
loaded. However the engines with the electronic governor
will keep the RPM and frequency at the set value. As the
voltage is related to the frequency, the voltage will be
more stable as well.
The RPM represents power and the alternator performs
better as well on a higher speed. Whisper models with an
electronic governor will bring more power.
So the electronic governor offers three advantages: a
more stable frequency and voltage and more power.
1
2
The actuator controls the engine speed. This actuator
replaces the standard hold solenoid that is on all other
mechanical controlled Whisper engines. The actuator
controls the RPM directly on the fuel rack inside the
fuel pump without levers and other mechanical
transmissions.
A microprocessor keeps the speed at the set value by
controlling the actuator. The microprocessor is
programmed at the WhisperPower factory and many
parameters are set to perform well. It should not be
necessary to make adjustments. When adjustments
are necessary this can only be done with the help of
an interface to a computer and special software to get
access to the microprocessor.
The WhisperPower electronic governor does not need a
pickup device in the flywheel housing that counts the
passing tooth of the flywheel and determines the exact
RPM of the engine, because the processor uses the 50 Hz
of the AC output voltage as a reference.
The electronic governor system contains two parts:

Check if installation conforms to the installation
instructions.
Ensure the generating set is free to turn without
obstruction.
Check all hoses and hose connections for leaks.
Check all cables and cable end terminal connections.
Check the engine and generator mounting bolts.
Routine "pre-start" checks:
1 Check engine oil level.
The generator switches off in the event of insufficient
oil-pressure. Even when the oil level is too low the oil
pressure can be high enough. Do not run the
generator with the oil below the lowest mark in the,
because a smaller volume of oil will become
contaminated considerably quicker than a larger
volume. 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 sea water cocks. Do not forget the valve of the
water outlet in case of a water/exhaust gas separator.
3 Check the water strainer.
4 Check for leaks.
5 Regularly check the siphon vent in the cooling water
supply.
6 If no Masterswitch is used: Switch main Power Source
Selector switch to "OFF" or switch off all devices.
7 Switch on the battery switch.
Starting the generator:
By pushing the start button briefly the electric system
is activated, the fuel lift pump starts pumping and the
starting procedure will begin. (By pushing the stop
button the system is deactivated)
The first time starting up or after running out of fuel it
could be necessary to prime the fuel system. (Refer to
bleeding fuel system instructions in the maintenance
chapter).
EN / M-SC6/8/10 / December 2010
A restart protection prevents starting the engine when it is
already running, which could cause damage.
In the event of starting problems (numerous
attempts are made), close the sea-water inlet
cock while cranking to prevent the outlet
system and engine to fill up with water.
During the starting process, the cooling water pump is
driven with the engine. The cooling water is discharged to
the exhaust outlet, because the engine does not run, the
exhaust pressure is not high enough to expel this water.
Open the valve directly when the engine starts to prevent
damaging the impeller.
Water in the cylinder will cause serious damage to the
engine. For instance; a bent piston rod or a cracked
cylinder head. In fact water in the cylinder is the main
cause for engine damage in pleasure craft.
Checks once the generator is in operation:

Check for abnormal noise or vibration.
Check the voltage.
Check coolant flow.
Always check immediately after starting the generator
if cooling water flows at the exhaust outlet. If this is
not the case, check the cooling water pump. After
having become acquainted with the generator you will
be able to recognise the coolant flowing through the
system by listening for the noise of the water which is
expelled.
Be aware that especially in harbours the
coolant water inlet can easily be blocked by
floating objects.

Power
source

(off/shore
power/generator power). Switch to power source

Before loading the generating set up to maximum,
have it run warm. The first 50 hours of running the
continuous load should be restricted to 70 % of maximum load. Running for long periods at no load or light
load in the first 50 hours can cause cylinder glazing
and high oil consumption.
21
OPERATION
Engine load during longer operation:
Please ensure that the generating set is not overloaded.
Overloading occurs when the electrical load (demand) is
so high that the generator cannot be turned around
properly by the diesel engine. Overloading causes the
engine to run rough, while using oil and excessive fuel and
producing soot by the exhaust. The engine can even stop.
Stopping the generating set:
1
Avoid stopping of the generator abruptly after a long
period of operation at high load! Doing so, you avoid
unnecessary thermal load to your generating set!
Act as follows:
Prior to switching off the generating set, decrease the
generator load (i.e. turn off most electrical users) and
let the generator run at low load for approx. 5 minutes
to allow the engine to get properly cool ( the influent
sea water must flow through the system in order to
cool the engine).
If the generator is operating in a hot environment and
you do not act as given above, the excessive heat in
the engine can trip the "high temp" alarms. In that
case, a restart of the engine is not possible for some
time. It is also recommended to switch off electrical
users prior to stopping the generator because of the
voltage drop that occurs as the engine comes to a
halt. Such voltage drops may cause damage to
electric motors, compressors (in refrigerators or air
conditioners etc.).
2
Press the STOP button.
3
Close the inlet sea water cock.
4
Switch to another 230V power source, if available. If a
Masterswitch is installed, this is done automatically.
The generator should therefore only 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 generating set’s life expectancy, the
nominal electrical demand on the system should be about
70% or the rated generating set’s maximum load. Please
note this when switching on your electrical devices!
Nevertheless, the M-SC6/8/10 is designed so as not to
overheat, even under extreme conditions.
Do not run the generator for very long periods at no load
or at very low load. When this is necessary do load the
generator at least one hour in 10 hours for minimum 70%.
Long term running at too low load will cause the exhaust to
be choked by carbon.
Never remove the battery while the engine is
running or any electrical cable while the
battery is connected in the circuit. Only
disconnect the battery with the engine
stopped and all switches in "OFF" position
22
If the engine is not running and ‘failure’ and
‘charging’ LED is blinking, reset by stop
button, otherwise it will drain the start battery

MAINTENANCE
4 MAINTENANCE
4.1
ALTERNATOR
The alternator does not require any maintenance. Periodic
inspection and cleaning is recommended, depending on
environmental conditions.
However when the alternator has been idle for a long
period attention to winding condition is recommended.
The condition of windings can be assessed by
measurement of insulation resistance to earth.
The CAPACITOR should be disconnected during this test.
A 500V ‘megger’ or similar instrument should be used. The
insulation resistance to earth of all windings should be in
excess of 1.0 MOhm. Should the insulation resistance be
less than this value, drying out the generator windings is
essential. Drying out can be carried out by direct warm air
from a fan heater or similar apparatus into the generator
air inlets or outlets.
All bearings are greased for life and not regreasable.
4.2
4.2.1
ENGINE
Preliminary instructions
All regular maintenance can be carried out when the
enclosure is open. When oil and dirt has gathered in the
enclosure measures have to be taken to avoid spilling oil
and polluting the environment.
The first service on the engine should be carried out after
50 hours of its life and after a major overhaul. In 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

Valve clearance
When the engine is in cold condition both valves (inlet and
outlet) should have a clearance between 0.25 mm. The
adjustment has to be done at TDC (refer to § 5.4.2).
4.2.4
Replacing fuel filter
Filter change depends on contamination of the fuel, but
should be done however, at least every 1000 running
hours. Before changing the filter, clamp off the supply line.
Remove the hoses from filter and attach them on the new
filter again. The arrow on the filter housing indicates the
direction of the flow. A clogged filter results in a lack of
output of the generating set.
4.2.5
Replacing oil filter
The oil filter is in front of the service side. Replacement
has to be executed according to the schedule in this
manual. Drain the oil using the sump pump and put some
tissues under the filter.
The first time starting up or after running out of fuel it could
be necessary to prime the fuel system.
4.2.2
Bleeding fuel lines
Ensure there is sufficient fuel. The system is self-bleeding.
The first time starting up or after running out of fuel it could
be necessary to prime the fuel system. Push the start
button activating the electric system and activating the fuel
pump. When more time is needed to bleed, push “start”
and hold on the local control panel (so not on the remote
panel) Hold as long as necessary to bleed the system.
Retighten the bleed screw when no further air bubbles are
expelled.

MAINTENANCE
A smeer of oil has to be put on the seal of the filter before
fitting the filter. The filter should be fastened manually:
when the rubber touches the metal turn 3/4 further.

AFTER FIRST 50 HOURS:
•
Change oil and replace the oil filter.
Have the engine run until it is on temperature and
stop it. Drain oil by the sump pump into a suitable
retainer and fill up with fresh oil. Start the engine
again and have it run for 5 minutes. Stop the
engine again and pause for a few minutes to let
the oil gather in the crankcase. Check the level
again and add oil when necessary.
•
Check and tighten nuts, bolts, and unions, paying
particular attention to the fuel system.
•
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.
•
Check air vent on a regular basis. When the air
vent it not working properly the engine can fill up
with water by siphoning. Water in the combustion
chamber causes serious damage to the engine.
•
Check and readjust V-belt.
•
Check the electrical connections
Figure 18
EVERY 150 HOURS:
•
Change oil.
•
Check the battery acid level (not applicable when
WhisperPower batteries are used).
•
Check battery terminals for corrosion
•
Check and readjust V-belt
•
Check impeller raw water pump (durability
depends on the purity of the sea water. In sandy
water and warm water wear will increase).
24
December 2010 / M-SC6/8/10 / EN
MAINTENANCE
When replacing the impeller the gasket between the pump
case and the cover should be replaced as well. So when
ordering a spare impeller order a gasket as well. 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.
4.3.1
EVERY 300 HOURS:
•
Replace the impeller of the raw water pump.
•
Retighten cylinder head bolts/adjust + valve
clearance.
•
Replace the oil filter.
•
Replace the fuel filter
Replacement depends or the condition of the
fuel. We recommend replacement every 300
hours. Isolate the fuel supply and change the
element.
EVERY 1000 HOURS:
•
Replace the V-belt.
•
Retighten cylinder head bolts/adjust + valve
clearance.
EVERY 2000 HOURS:
•
Check lubricating oil pressure
•
Clean and check or replace fuel injector nozzles
and check injection pressure.
•
Check the air filter element:
The air is taken in via the cover on the alternator.
Below this cover is a spongy material which filters
the air and holds some electrical components

not require regular maintenance. Only in very
dusty circumstances this filter should be cleaned.
The spongy material can be washed in solvent or
replaced.
•
Check the cooling system:
The engine cooling liquid is indirectly cooled by
raw water via a heat exchanger. The alternator is
cooled by seawater which is pumped by the PTO
driven impeller pump through the cooler elements
in the generator housing. All parts of the cooling
system are of corrosion free and seawater
resistant materials such as brass and gunmetal.
In case of gathering of dirt in the system it could
be cleaned by compressed air. When overhauling
the engine one could clean the parts thoroughly
or replace.

draws too much current during starting
Check the electric motor’s current draw
required for starting. This should not exceed
the rated generator peak output current. This
could be remedied by providing stronger
capacitors to the motor or using a "soft-start".

TROUBLE SHOOTING
5.2
ENGINE FAULTS
Remove 3 Amp. fuse in the control panel
while working on the generator to prevent the
engine from starting.
5.2.1
When the engine does not start instantly,
prolonged cranking can fill up the exhaust
system with cooling water because of the
water injected exhaust. When the water
enters the cylinder through the valves this will
bring severe damage to the engine. When the
engine does not start and repeated cranking
is necessary shut off the seawater inlet. Open
the valve immediately after the engine has
started.
General
Most electrical problems relating to Voltage or Frequency
are due to wrong engine speed.
Note that RPM and Hz are basically the same.
Use the problem solving table to find the cause of a wrong
engine speed. When there is no obvious cause one can
adjust the RPM (refer to special procedures). When the
engine is not cranking well, starting problems almost
always originate from battery problems or poor battery
cable connections.

PROBLEM
CAUSE
SOLUTION
Diesel engine fails to crank, the
starter makes clicking noises, or
the engine cranks very slowly
• Almost certainly this is an electrical
problem. Display will indicate “LOW
START BAT”
• One other possibility is that the engine
is locked by water in the cylinder or
there is other severe damage.
Check on water in the cylinder and further
damage by cranking. When there is water in
the cylinder, then deactivate the control
system, disconnect the battery, remove the
glow plugs. Crank the engine to remove the
water through the opening of the glow plugs.
Check oil on the presence of water and
change oil. Find out how the water did enter
the cylinder (check the air vent). Take
precautions to prevent it from happening
again. When there is no mechanical
malfunction the problem must be an electric
malfunction.
Check position of the battery switch and switch
"ON".
Check battery voltage. Recharge the battery.
Inspect battery terminals and cables for a good
electrical connection (inspect against
corrosion, tattered wires, etc.)
Replace fuse
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.

Residual voltage check / excitation
procedure
5.3.2
Testing rotary rectifier diodes
The diodes in the rotor can be checked with a multimeter.
When the diode is faulty the alternator will not generate
any voltage.
When residual magnetism disappears there is no residual
voltage. Residual magnetism can disappear after the
generating set being out of service for a long period or
suffered a short circuit. This can be solved by charging the
capacitor ("flashing") independently with a small 9 Volt
battery. This can be done while the engine is stationary
and the wiring is connected.
DIODE
Fig. 21
The flexible lead connected to the diode should be
disconnected at the terminal end, and the forward and
reverse resistance checked. A healthy diode will indicate a
very high resistance (infinity) in the reverse direction, and
a low resistance in the forward direction. A faulty diode will
give a full deflection reading in both directions with the test
meter on the 10,000 ohms scale, or an infinity reading in
both directions. Replace the diode.
Fig. 20
If the generating set battery is used for
flashing one must take care. A short circuit
can cause heavy sparking, fire and injuries
When flashing does not bring back voltage, the
capacitor(s) should be renewed. When this does not help,
the rotating rectifier diodes should be tested and a winding
resistant test should be executed.

SPECIAL PROCEDURES ENGINE
Setting the RPM
RPM is set by the manufacturer and should not need
readjustment! However a very slight offset after running in
could occur. RPM can be measured by a frequency meter.
M-SC8 and 10: When adjustments are necessary this can
only be done with the help of an interface to a computer
and special software to get access to the microprocessor.
If readjustment of the RPM is necessary, please contact
your WhisperPower Service Centre for advice.
M-SC6: Before readjustment check any other explanation
for the wrong speed. Engine speed is set at the factory at
nominal 3000 (50 Hz) RPM. A RPM drop of 5% at full load
is acceptable. Therefore a no load setting should be at ±
3150 RPM = 52.5 Hz. Under no circumstances should the
RPM be under full load below 2940 RPM = 49 Hz.
When no cause can be found for a wrong speed, the
setting can be adjusted:
Meggering
One can try to measure resistance between the housing
and the windings with a multimeter which should read
infinity. When readings are infinity but a fault is suspected
one can do a high voltage resistance test (MEGGERING)
This procedure should be carried out by an expert

To take the generating set out of the canopy all hose
and cable connections have to be taken off. The set is
fixed to its base by four rubber mountings and can be
loosened by removing the four nuts from the bolts of
these mountings. Moreover the generating set is fixed
by 2 fail safes which prevent the generating set from
getting loose if the rubber mountings should break
down. The nuts of the fail safes are diagonal to each
other. When the 6 nuts in total are removed the
generating set can be lifted out the canopy. 5 nuts are
well accessible. The sixth nut has to be removed by
taking out the bold from the bottom of the canopy.

The easiest way to get the generator out of its capsule
is by lifting the set using the lifting eye and removing
the capsule downwards.

The cooler elements are welded to the alternator
housing with silver and cannot be disassembled. However one can take off the complete alternator housing.

Before the alternator can be taken off one has to take
out the fitting to the oil cooler to be able to take off the
aluminium housing. All cables and wiring have to be
loosened first.

The rotor can be taken off by removing the bolt which
goes through the shaft (normal clockwise threaded).
The end of the shaft is specially threaded to push off
the rotor from the conic stub shaft, which is on the
flywheel, using a 6-mm rod of 165-mm (M-SC6 and 8)
/ 185mm (M-SC10) length and a M10 bolt.
