INTRODUCTION

EN / M-SC6/8/10 / December 2010 5

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

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.

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

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.

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.

1.5 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 Identification plate

All required identification data are on the identification plate. For location of the identification plate see figure 1.

Figure 1: Location identification plate

1 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

identification plate are also some basic features of the set:

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.

Safety also relies on the installation, application and circumstances. See also the remarks in this manual under SAFETY.

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.

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.

• 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.

• 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.

2.1.3 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.

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.

2.1.4 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.

2.1.5 Operation

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.

Nevertheless take note of the signs on the generating set which show symbols in a triangle indicating danger.

When service has to be carried out while the engine is running, be aware of moving parts like V-belts.

• 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.

• 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.

2.1.6 Fire and explosion

Fuels can be flammable. Proper handling limits the risk of fire and explosion.

• Avoid refilling the fuel tank while the engine is running. When oil or fuel is leaking do not use the generating set.

• 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.

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)

• While the battery is stored it should be recharged every 12 weeks.

2.3 THE M-SC6/8/10

2.5 TECHNICAL INFORMATION

2.5.1 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.

2.5.2 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!

2.5.3 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.

INFORMATION

14 December 2010 / M-SC6/8/10 / EN

2.5.4 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 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.

2.5.6 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.

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

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 CD, CF or CF_4.

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.

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.

4 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.

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

Page 15

INFORMATION

EN / M-SC6/8/10 / December 2010 15

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.

2.6 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.

The electronic governor system contains two parts:

1 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.

2 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.

3 OPERATION

3.1 GENERAL

The generating set is operational after full installation and filling up with: fuel, engine lubricating oil and cooling liquid, filling the starter battery with acid, connecting the battery to earth and connecting the digital remote control panel.

Fig. 14:

3.2 OPERATING INSTRUCTIONS

3.2.1 Summarised operating instructions (daily use)

Routine "pre-start" checks: 1 Check oil level (refer to fig. 14). 2 Engine cooling system (all valves open). 3 Power source selector switch (off/shore

power/generator power). Switch to power source switch "OFF", or switch off all consumers in the usual

way. 4 Switch on battery switch (when installed). 5 Fuel valve: open.

Starting:

Push the start button to initiate the full automatic

starting procedure. You can monitor the procedure on

the display.

In operation checks: 1 Check for abnormal noise or vibration 2 Check the voltage 3 Check sea water flow at exhaust outlet 4 Power source selector switch (off/shore

power/generator power). Switch to power source generator. If a Masterswitch is installed, this operates automatically.

5 Before loading the generating set up to maximum,

have it run warm. Continuous load should be restricted to 70 % of maximum load.

Stopping generator: 1 Switch off all electrical devices (consumers). If the

generating set 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 approx. 5 minutes. 2 Press the STOP button. 3 Close the inlet sea water cock. 4 Switch to another AC power source, if available.

OPERATION

EN / M-SC6/8/10 / December 2010 21

3.2.2 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 installation conforms to the installation

instructions.

3 Ensure the generating set is free to turn without

obstruction. 4 Check all hoses and hose connections for leaks. 5 Check all cables and cable end terminal connections. 6 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).

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:

1 Check for abnormal noise or vibration. 2 Check the voltage. 3 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.

4 Power source selector switch (off/shore

power/generator power). Switch to power source generator. 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.

Page 22

OPERATION

22 December 2010 / M-SC6/8/10 / EN

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.

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

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.

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

EN / M-SC6/8/10 / December 2010 23

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 ENGINE

4.2.1 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

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.

Figure 15: Bleeding fuel lines 1 = Fuel bleeding screw

4.2.3 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.

Figure 16

Page 24

MAINTENANCE

24 December 2010 / M-SC6/8/10 / EN

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.

Figure 17

4.2.6 Readjustment of the V-belt

The alternator bracket allows for readjust of the V-belt. Deflections should be 10 mm (refer to fig. 18)

Figure 18

4.3 REGULAR MAINTENANCE

CHECK DAILY:

• Oil level (see fig. 19)

Take care the oil level is never below the mark. Do not oil when the level is still above the mark

1 Minimum oil level 2 Maximum oil level

Fig. 19:

CHECK DAILY:

• Level cooling liquid

• Hoses for loose connections or deterioration.

• Water inlet filter.

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

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).

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.

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 which are cooled by the inlet air. This filter does 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.

When the generator set runs less than 100 hours a year the oil should be changed yearly

4.3.2 Putting out of service

When not using the generating set for a longer period it is recommended to execute 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. Start the engine and run the engine warm.

3 Drain the hot engine oil and refill with preservation oil.

4 Stop the engine and take loose the inlet of the raw

water pump. Drain the water from the water lock. Crank the engine having the raw water inlet sucking

anti-freeze from a can until the pump, heat exchanger and manifold are filled.

5 The coolant can stay in the engine

6 Disconnect the battery and store it in a place free of

frost and dry and charge it regularly.

7 Close inlet- and outlet openings with tape.

8 Protect the generating set against the influences of

bad weather conditions.

This method of preservation will be sufficient for 6 months. Repeat steps 2, 3, and 4, every 6 months. Change oil before using the engine again.

5 TROUBLE SHOOTING

5.1 ALTERNATOR/ ELECTRICAL FAULTS

Beware of parts which are live!

Remove 3 Amp. Fuse in the control panel while working on the generator to prevent the engine from starting

A failure code is displayed when a hardware failure at the generator is detected

5.1.1 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. These measurements should only be carried out by an experienced electrician If during these measurements the engine immediately stops after starting and an error code is displayed at the remote control panel ( “AC VOLTAGE”), one can start the generator by means of a “service start” at the service

menu (see paragraph “service start” of the user’s manual of the Digital Diesel Control). By doing this, the generator 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. Check if the engine is running correctly at 3000 RPM (50 Hz) according to its settings and does as well under load.

• M-SC6: 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 under full load be below 2940 RPM = 49 Hz.

• M-SC8 and 10: A RPM drop of 1% at full load is

acceptable. Therefore a no load setting should be at 3030 RPM = 50.5 Hz. Under no circumstances should the RPM under full load be below 2970 RPM = 49.5 Hz.

When the problem is in the RPM refer to the engine fault finding paragraph. Digital Diesel Control system will help to indicate failures and display causes

Check engine speed and adjust (refer to special procedures).

• Over-energising due to defective capacitors

Check capacitor specification and replace capacitors if necessary.

• Presence of a strong capacitive load (leading power factor)

Compensate for this capacity and seek for experts advice (WHISPERPOWER customers service)

• Defective voltage regulator (Optional for M-SC8/10)

Replace voltage regulator

Generator voltage fluctuates.

• Disturbances on the electrical system/ user side.

Check if electrical load is fluctuating

• Engine runs irregularly.

When engine runs irregularly refer to section: "Engine runs irregularly".

Generator is not able to start an electric motor

If the generator is unable to supply enough power to start an AC electric motor, this is usually because this motor 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". Inquire at your nearest WhisperPower dealer or directly at the manufacturer, WhisperPower in the Netherlands.

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 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.

When the engine is cranking, well starting problems almost always originate from lack of fuel or air bubbles in the fuel pipes.

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.

A failure code is displayed when a hardware failure at the generator is detected.

5.2.2 Trouble shooting table

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.

• Starter battery switched "OFF".

Check position of the battery switch and switch "ON".

• Starter battery voltage insufficient (battery too weak).

Check battery voltage. Recharge the battery. Inspect battery terminals and cables for a good electrical connection (inspect against corrosion, tattered wires, etc.)

• Faulty fuse

Replace fuse

• Wing control 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.

• Starter broken

5.3 SPECIAL PROCEDURES ALTERNATOR

5.3.1 Residual voltage check / excitation procedure

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.

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.

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.

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.

5.3.3 Winding resistant values

If after establishing and correcting any fault on the capacitor and diodes output is still low when separately excited, then the main rotor, stator and exciter stator winding resistance should be checked as the fault must be in one of these windings. The respective leads must be disconnected before taking the readings. Resistance values should be within 10% of the values given in the table below:

M-SC6 and 8

Resistance 50Hz

• Resistance both main stator windings in series

0.54 Ohm

• Resistance both rotor windings

0.93 Ohm

• Resistance exciter stator winding

1.4 Ohm

M-SC10

Resistance 50Hz

• Resistance both main stator windings in series

0.36 Ohm

• Resistance both rotor windings

1.05 Ohm

• Resistance exciter stator winding

0.85 Ohm

5.3.4 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

5.4 SPECIAL PROCEDURES ENGINE

5.4.1 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:

Fig. 22 2= adjustment screw RPM

3= manual stop

It is very important to identify the correct setting assembly (refer to fig. 22).The screw is to be locked in position with the lock-nut.

5.4.2 Adjusting valve clearance and retightening the cylinder head bolts.

Both procedures have to be carried out with a cold engine. When both procedures are carried out be sure to retighten the cylinder head bolts before adjusting the valve clearance. When retightening the cylinder head bolts, drain the coolant by removing the drain plug (ref. to fig. 2).

Loosen the bolts slightly, remove the rocker assembly (the rocker arms, shaft, and stays) and then retighten the bolts to the specified torque in the numerical order illustrated (ref. to fig. 23).

Tightening torque: M10 bolt 75-85 Nm M8 bolt 20-30 Nm Rocker stay tightening torque: M8 bolt 15-22 Nm

The clearance of both (intake and exhaust) valves should be 0.25 mm in cold condition. 1 Set the piston of the first cylinder to be adjusted to top

dead centre (T.D.C.) of compression stroke.

2 The T.D.C. of compression stroke can be found by

aligning the T.D.C. mark (notch) on the crankshaft pulley with the mark on the gear case (ref. to fig. 24).

3 First align the T.D.C. mark for the No. 1 cylinder.

Confirm that the valves do not move up or down when the crankshaft is turned about 20 degrees in normal and reverse direction of rotation. If the rocker arms move piston no.1 is on the T.D.C. of the intake or exhaust stroke. In such case turn the crankshaft 360°

in the direction of engine rotation again. No. 1 piston is now at T.D.C. of the compression stroke.

4 To adjust the valve clearance of the No. 2 and No.3

cylinder

a. Two cylinder engine (M-SC6 and 8): the

crankshaft pulley has to be turned 180 degrees clockwise to set this piston to T.D.C. Adjustment can be executed.

b. Three cylinder engine (M-SC10): After adjusting

the valves of cylinder 1 turn the crankshaft 240 degrees clockwise from the T.D.C of cylinder 1 to the T.D.C of cylinder 3. Position 2 fig. 24b against the notch. Adjust the valves of cylinder

3. Then turn the crankshaft 240 degrees further clockwise to the T.D.C of cylinder 2 and adjust the valves; position 3 fig. 24b against the notch.

Check after each adjustment that the valves do not move up and down when turning the crank craft about 20 degrees clockwise and counter clockwise of T.D.C.

5.4.3 Measuring exhaust backpressure

The exhaust system must be of adequate size -1 5/8”/ 40 mm - and maximal length (refer to installation manual). When any doubt; backpressure has to be measured. An easy way to measure for back-pressure is to use a water column. A water column can be made visible in a plastic tube along a yardstick and fitting the end to a hose connection to fit in the adaptor on the injection bent after removing the exhaust temperature switch.

Figure 25: Measuring exhaust backpressure

The bent A hanging down should not be to short helping to damp the pulsating effect of the gas discharge that is characteristic for a one cylinder engine. The water column should be no more than 27 inches (69 cm.) of water (1 PSI

- 0,07 bar)

5.4.4 Disassembling instructions

It could be necessary to disassemble the generating set for repair or checks. Following instructions will help:

1 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.

2 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.

3 The cooler elements are welded to the alternator

housing with silver and cannot be disassembled. However one can take off the complete alternator housing.

4 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.

5 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.

6 Reassembling the generating set one should take

care of alignment, cleaning the surfaces between engine and alternator and tighten the bolts crosswise and gradually.

7 Use Loctite 577 to seal the fittings, which should first

be cleaned and made free of oil and grease.

8 Test the generating set first outside its capsule and

check very carefully for leakages before putting it back in its enclosure.
