INTRODUCTION

1 INTRODUCTION

1.1 GENERAL

The Whisper 16 ULTRA Mobile Diesel Generating set is

manufactured and marketed by Mastervolt.

It is important to read this manual before installing and

operating the generating set. Both safety and durability

rely very much on the correct identification, installation

and a well understanding of ratings, features, design,

maintenance and operation procedures.

The information, specifications, illustrations and state-

ments contained within this publication are given with our

best intentions and are believed to be correct at the time

of going to press.

Our policy is one of continued development and we re-

serve the right to amend any technical information with-

out prior notice.

Whilst every effort is made to ensure the accuracy of the

particulars contained within this publication neither the

manufacturer, distributor, or dealer in any circumstances

shall be held liable for any inaccuracy or the consequen-

ces thereof.

WARNING:

A warning symbol draws attention to spe-

cial warnings, instructions or procedures

which, if not strictly observed, may result in

damage or destruction of equipment, seve-

re personal injury or loss of life.

DANGER:

This danger symbol refers to electric dan-

ger and draws attention to special war-

nings, instructions or procedures which, if

not strictly observed, may result in electri-

cal shock which will result in severe per-

sonal injury or loss of life.

Realise that people are not used to have

230V available on a vehicle. Put warning

signs on wall sockets and on junction

boxes. Instruct non-regular users of the

vehicle. Warn maintenance personal of

garages that do service on the vehicle.

1.2 SERVICE AND MAINTENANCE

Regular service and maintenance should be executed

according the directions in this manual. For service and

maintenance one can appeal to the manufacturer or the

dealers.

1.3 GUARANTEE

Mastervolt guarantees that this generating set has been

built according to good workmanship, according to the

specifications in this manual and according to European

Community safety regulations.

During production and prior to delivery, all of our genera-

ting sets are tested and inspected.

The well functioning of this generating set is subject to

guarantee. The period and conditions of this guarantee

are laid down in the general conditions of delivery as

registered with the Chamber of Commerce and Industries

in Amsterdam number 33279951 and are available on

request. The guarantee period is two years, limited to

1000 running hours. Some aspects of the warranty

scheme are given here in more detail:

Guarantee period 1000 running hours or 24 months

whichever occurs first. Warrantee does not cover failures

that are caused by misuse or a faulty installation.

Example 1: Faulty installation

Overheating of the engine is the most common cause of

problems with mobile generating sets. These problems are

caused by poor circulation of the cooling liquid due to wrong

routing of the pipes to the radiators: bents will capture air

bubbles causing “air-lockes” blocking the circulation of the

liquid. Other examples of installation problems are hot air

circulation into the radiators and the radiator fans sucking

exhaust gasses into the radiators.

The generator and other parts should be protected against

the influences of the weather and splashing water (with dirt

and salt) below the vehicle. Refer the installation manual.

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

Whisper generators have an option for an auto start/stop

mode or interval mode.

Mastervolt cannot be held responsible for damage

caused by the unattended running generator.

Warranty 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

INTRODUCTION

board a vehicle executed by an authorised 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 vehicle or for

reinstallation. There is no cover for labour needed to get

access to the generator, for example to remove

equipment or parts of the carroserie 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 warranty a credit will not be issued. For example if a

Printed Circuit Board is returned with clear damage

caused by water, warranty will be refused. Freight costs

to deliver spares by normal mail or carriers is covered

under warranty. 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

warranty.

If any problem arise which could be subject of guarantee,

procedures should be followed as described in the gua-

rantee certificate, unauthorised repairs could lead to furt-

her damage and violate the guarantee conditions and are

not refunded.

Should work take place, which is not in ac-

cordance 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 specifica-

tions. In all these cases the guarantee may

become invalid. Use original parts only.

1.4 LIABILITY

Mastervolt 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. Mastervolt does not accept liabi-

lity for damage due to use of the generator, possible errors

in the manuals and the results thereof.

Automatic start/stop

Mastervolt cannot be held responsible for damage

caused by the unattended running generator using

the auto-start/stop mode or interval mode.

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 genera-

ting set it is necessary that the operator knows the cor-

rect specifications.

1.5.2 Nameplate

All required identification data are on the nameplate.

1 The identity of the generating set is given by the SE-

RIAL NUMBER.

When this number is available the manufacturer can

trace the specifications of the generating set. On the

nameplate are also some basic features of the set:

2 POWER

The nameplate gives the nominal maximum load in

kVA = kW calculated with the indicated power factor

one. When calculating a load one should always take

1150x680x750 mm

2.1.1 General

When correctly installed and used in normal circumstan-

ces 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 has to be taken into account.

Circumstances could make it also neces-

sary to take additional measures. Be awa-

re of wet conditions and hazardous envi-

ronment caused by explosive gasses etc.

2.1.2 Electrical safety

The voltage of 230 Volt generated by this

generating set is dangerous and if instruc-

tions and procedures are not strictly obser-

ved may result in electrical shock which

will result in severe personal injury or loss

of life.

Realise hat people are not used to have

230V available on a vehicle. Put warning

signs on wall sockets and on junction

boxes. Instruct non-regular users of the

vehicle. Warn maintenance personal of

garages that do service on the vehicle.

• 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 chan-

ges in your electrical system to be carried out by

qualified electricians.

• Connection and protection must be done in accor-

dance 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.

INFORMATION

into account the power factor or Cos phi of this load.

The power should never exceed the nominal Power

in kW as shown on the nameplate. Power is rated at

an ambient temperature of 40°C and a seawater tem-

perature of 25ºC. For higher temperatures the gene-

rating 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

1500 rpm.

5 CURRENT shows the maximum current that is ac-

ceptable at the specified frequency, voltage and po-

wer factor.

6 WEIGHT shows the net dry weight (approximately) in

kg. This is without fuel, oil, cooling liquid, 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, regarding electric safety

and electric magnetic compatibility (EMC).

Safety also relies on the installation, application and cir-

cumstances. See also the remarks in this manual under

SAFETY

Before changing a factory setting you are advised to con-

sult the manufacturer. When the generating set you have

to identify is not new you have to take into account the

possibility that former users did change the settings.

Check the settings (voltage, frequency, rpm) when any

doubt.

INFORMATION

2.1.3 Earth insulation failures

According to local regulations and depending on the ap-

plication 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.

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

Mastervolt Masterswitch.

2.1.4 Installation

Whisper generating sets are not self contained and have

to be properly installed in enclosed areas. Installation

includes measures to be taken to outlet exhaust fumes

which contains carbon monoxide and are extremely

dangerous. Carbon monoxide (CO) is an invisible

odorless 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.

Do not use the generator set when the

vehicle is inside a building or in other

enclosed area’s.

Be aware using the generator in windstill

conditions, when the exhaust fumes could

accumulate under, around or even in the

vehicle.

2.1.5 Operation

External moving parts like fans and V-belts are covered

by the canopy and therefore the Whisper 16 ULTRA is

very safe, when the canopy is closed

Never the less take note of the signs on

the generating set which shows symbols in

a triangle indicating danger.

• When service has to be executed while the

engine is running, be aware of moving parts like

V-belts.

• The generating set should be operated by authori-

sed personnel only.

• Be aware of hot parts and specially parts of the

exhaust 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 cor-

rected.

• 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 executing

maintenance.

• Do not change the settings without consulting the

manufacturer. Keep record of changing of the set-

tings 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. Take measures 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 conta-

minated by fuel or lubricating oil.

INFORMATION

• 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 400ºC 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 for 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 mi-

nimise 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 recharge

every 12 weeks.

2.5 TECHNICAL INFORMATION

2.5.1 AC alternator

The single phase synchronous alternator is directly

coupled, one bearing, brushless, rotating field design,

four pole (1500 RPM) and self regulating.

Residual magnetism causes a small voltage over the sta-

tor windings and allows a current to flow in the windings,

which is magnified because of the feed back effect be-

tween rotor and stator. The field windings in the rotor are

short-circuited over a diode to rectify the current. A capa-

citor over an additional winding in the stator which is in

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.

Further technical data on the design of the alternator can

be found in drawings and diagrams in this manual. The

alternator is watercooled and the cooling liquid is cooled

by a radiator.

2.5.2 Engine

The Whisper generating set is based on the Mitsubishi

S4Q2 4 cylinder diesel engine. The engine is indirectly in-

jected. The engine is water cooled and the cooling liquid is

cooled by a radiator.The engine has been specially adapted

for the Mastervolt application and is very different from the

standard engine as 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 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 users manual.

The microprocessor unit is located on top of the alternator.

2.5.4 Battery charger

On the engine is an alternator generating 50 Amp 12V.

This current is rectified to charge the battery. The

voltage is regulated at 14.2V.

INFORMATION

lure light and detail will be shown on the display the

engine will be shut down. There are three functions

guarded: oil pressure, coolant temperature and alternator

temperature. Exhaust temperature too high indicates the

alternator cooling water to be blocked. All alarm switches

are closed when no malfunction occurs. A contact is cut

in case 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 automaticly. Pushing the STOP

button will stop the engine and the electrical system will

be deactivated. Stopping the engine is executed by the

fuel valve solenoid that will shut off.

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 neces-

sary an optional longer 8 wire twisted cable can be

connected if the standard length does not suit the requi-

red 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 and

helps to schedule maintenance.

2.5.9 Load indicator

On the remote control the load will be indicated on the

display and by the LEDbar. The load is measured by

current transformers on the alternator.

2.5.10 Fuel specification

The engine must only be used with diesel fuel oil which

conforms the standards for use in modern diesel en-

gines. Fuel free from water and contaminants is of the ut-

most importance.

2.5.11 Oil information

1Specification:

The oil must be suitable for oil changes as specified

in the maintenance chapter. The Mitsubishi engine

must be run on heavy duty lubricating oil meeting the

requirements of API class CC or CD.

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 this

recommendations.

Using the wrong specification will cause

high oil consumption.

2 Oil viscosity:

We recommend a multigrade oil 10W40.

3 Oil capacity:

Excluding the oil filter the content of the crankcase is

7 l. Including the oil filter it is 8 l.

Do not overfill with lubricating oil as this may have a

detrimental effect on engine performance.

4 Oil pressure

• Minimum at idle 98 Kpa (1 kgf/cm2)(14psi)(1 bar).

• Normal at 1500 rpm ±196 to 392 Kpa (2 to 4

kgf/cm2) (28 to 57 psi) (2-4 bar)

2.5.12 Cooling liquid

The engine and alternator are cooled by cooling liquid.

The capacity of both systems depend on the capacity of

the radiator piping and other parts of the 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 until minus 25° C.

Also it protects the engine block against corrosion.

Initially one can fill the engine via the filling cap on the

exhaust manifold. Fill up till the level is just below the

filling cap. Filling of the alternator cooling system and

additional filling of engine cooling system has to be done

via the expansion tanks. When the engine is on

temperature the liquid will expand and the redundant

liquid will be pressed into the expansion tank. This tank

has to be filled up till the mark. On the tank is an overflow

connection. This should be open hose can be connected

to drain the overflow to outside the vehicle. When cooling

liquid is not available clean sweet water could be used

with an additive of anti freeze. When using water with

anti freeze the right mixture has to be cal-culated

according to the information of the supplier of the anti

freeze. The cooling system is not pressurised. There

should be a special cap on the engine manifold without

valves leaving the connection to the expansion tank

open.

OPERATION

3 OPERATION

3.1 GENERAL

The generating set is operational after full installation and

filling up with: fuel, engine lubricating oil and cooling li-

quid, filling the starter battery with acid, and connecting

the battery to earth.

3.2 OPERATION INSTRUCTIONS

3.2.1 Summarised operating instructions (daily use)

Routine "pre-start" checks:

1Check oil level (refer to fig. 10).

2 Check cooling system (coolant levels).

3 Power source selector switch (off/shore power/gene-

rator power). Switch to power source switch "OFF", or

switch off all consumers in the usual way. If a MAS-

TERSWITCH is installed, this is operating automati-

cally.

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 Power source selector switch (off/shore power/gene-

rator power). Switch to power source generator. If a

MASTERSWITCH is installed, this is operating auto-

matically.

4 Before loading the generating set up to maximum,

have it run warm. Continuous load should be restric-

ted 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 Switch to another 230V power source, if available. If

a Masterswitch is installed, this is done automatically.

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 instal-

lation.

2 Check if installation conforms with the installation

instructions.

3 Ensure the generating set is free to turn without ob-

struction.

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 case of insufficient oil-

pressure. Even when the oil level is too low the oil

pressure can be high enough. Do not run the

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.

OPERATION

Starting the generator:

By pushing the start button briefly the electric system

is activated 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 for starting the engine while

already running which could cause damage.

Checks once the generator is in operation:

1 Check for abnormal noise or vibration.

2 Check the voltage.

3 Power source selector switch (off/shore power/gene-

rator power). Switch to power source generator. If a

MASTERSWITCH is installed, this is operating auto-

matically.

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 maxi-

mum load. Running for long periods at no load or light

load in the first 50 hours can cause cylinder glazing

and high oil consumption.

Engine load during longer operation:

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 rum 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 expectance,

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 Whisper 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:

1Avoid 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 elec-

tric motors, compressors (in refrigerators or air condi-

tioners etc.).

2 Press the STOP button.

3 Close the inlet sea water cock.

4 Switch to an other 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 but-

ton, otherwise it will drain the start battery.

4 MAINTENANCE

4.1 ALTERNATOR

The alternator does not require any maintenance. Perio-

dic 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 measure-

ment 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 genera-

tor 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 executed when the en-

closure is open. When oil and dirt has gathered in the

enclosure measures has 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 consump-

tion.

For the same reason it is of the greatest

importance to use the right oil specifica-

tion.

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 Whispers are self

bleeding. To check the well functioning release the

bleedscrew on the high pressure fuel pump. Turn loose

the cap of the fuel lift pump and move the piston up and

down to prime the system. Retighten the bleed screw

when no further air bubbles are expelled. Retighten the

cap when ready.

4.2.3 Valve clearance

When the engine is in cold condition both valves 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 300 running.

A clogged filter results in a lack of output of the

generating set. (Refer to Fig. 13)

4.2.5 Replacing the 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.

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.

4.2.6 Readjustment V-belt

The alternator bracket allows to readjust the V-belt. De-

flections should be 10 mm (refer to fig. 14).

4.3 REGULAR MAINTENANCE

CHECK DAILY:

• Oil level (see fig. 15)

Ta ke care the oil level is never

below the mark. Do not add oil

when the level is still above the

mark.

CHECK DAILY:

• Level cooling liquid.

• Hoses for loose connections or deterioration.

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 engi-

ne 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.

• Retighten the cylinder head bolts and adjust the

valve clearance. (Refer to paragraph 5.4.2)

• 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 investi-

gating the cause as this may result in an expensi-

ve breakdown.

• Check and readjust V-belt.

EVERY 100 HOURS:

• Change oil.

• Check the battery acid level.

• Check battery terminals for corrosion

• Check and readjust V-belt.

EVERY 300 HOURS:

• Check impeller water pump

•Check 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 500 HOURS:

• Replace the impeller of the water pump.

• 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.

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 cooled by radiator.

The alternator is also cooled by radiator. The

alternator is pumped by the PTO driven impeller

pump through the cooler elements in the ge-

nerator housing.

When the generator set runs less than 100

hours a year the oil should be changed

yearly.

4.3.1 Maintenance schedule

4.3.2 Putting out of service

When not using the generator for a longer period it is re-

commended 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 The coolant can stay in the engine.

5 Disconnect the battery and stock it in a place dry and

free of frost and charge it regularly.

6 Close inlet- and outlet openings with tape.

7 Protect the generating set against the influences of

bad weather conditions.

This way of preservation will be sufficient for 6 months.

Repeat step 2, 3, and 4, every 6 months. Change oil

before using the engine again.

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 direct on the alternator

This should only be carried out by an experienced

electrician.

Check if the engine is running correctly at 1500 RPM (50

Hz) according to its settings and does as well under load.

A RPM drop of 5% at full load is acceptable. Therefore a

no load setting should be at 1575 RPM = 52.5 Hz . Under

no circumstances the RPM under full load should be

below 1470 RPM = 49 Hz.

5.2.3 Warnings

Generator must be shut off immediately if:

• Motor RPM suddenly rises or drops.

• Unusual noise comes from generating set.

• Exhaust gases suddenly colour dark.

• Engine failure warning light is on

5.2.4 Service address

If you cannot correct a problem with the aid of the mal-

function table, contact your Mastervolt Service Centre or

Mastervolt Amsterdam for an extended service list, tel:

INT +31-20-3422100. www.mastervolt.com

5.3 SPECIAL PROCEDURES ALTERNATOR

5.3.1 Residual voltage check / excitation procedure

When residual magnetism disappears there is no resi-

dual voltage. Residual magnetism can disappear after

the generating set being a long period out of service or a

short circuit. This can be solved by charging the capa-

citor ("flashing") independently by a small 9 Volt battery.

This can be done while the engine is stationary and the

wiring is connected.

If the starter 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 capaci-

tor(s) should be renewed. When this does not help, the

rotating rectifier diode should be tested and a winding re-

sistant test should be executed.

5.3.2 Testing rotary rectifier diode

The diode 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 dis-

connected 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:

Resistance Whisper 16 ULTRA 50Hz-230V

• Resistance both main stator windings 0.18 Ohm

in series

• Resistance both rotor windings 3,90 Ohm

• Resistance exciter stator winding 0.42 Ohm

5.3.4 Meggering

One can try to measure resistance between the housing and

the windings by a multimeter which should read infinitely.

When readings indicate 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.

Before readjustment check any other explanation for the

wrong speed. Engine speed is set at the factory at nominal

1500 RPM (50 Hz). A RPM drop of 5% at full load is

acceptable. Therefore a no load setting should be at + 1575

RPM = 52.5 Hz. Under no circumstances the RPM under full

load should be below 1470 RPM = 49 Hz. When no cause can

be found for a wrong speed, the setting can be adjusted: It is

very important to identify the correct setting assembly (refer to

fig. 18). 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 has to be executed with a cold engine.

When both procedures are executed be sure to retighten

the cylinder head bolts before adjusting the valve clea-

rance. When retightening the cylinderhead 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. 19). Tightening torque cylinder head

bolt: 118 ± 5 Nm Rocker stay tightening torque: long bolts

15 ± 2 Nm short bolts 12 ± 1 Nm

The clearance of both valves intake and exhaust should

be 0.25 mm in cold condition. Set the piston of the first

cylinder to be adjusted to top dead centre (T.D.C.) of

compression stroke.

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

aligning the T.D.C. mark -0- on the crankshaft pulley with

the mark on the gear case (ref. to fig. 20).

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.

After adjusting the valves of cylinder 1 adjust the valve

clearance of the remaining cylinders in firing order: 1-3-4-

2. Turn the crankshaft 180 degrees clockwise from the

T.D.C of cylinder 1 to the T.D.C of cylinder 3. Adjusts the

valves of cylinder 3 and turn the crankshaft 180 degrees

further clockwise to the T.D.C of cylinder 4 and adjust the

valves. And again 180 degrees to adjust 2.

5.4.4. Disassembling instructions

It could be necessary for repair or checks to disassemble

the generating set.

Following instructions will help:

1 The design of the Whisper 16 makes it possible to do

most repairs on the spot. The heatexchanger is

accessible and can be removed. The connections of

the alternator are very accessible as well. The same

is true for the diode of the rotor.

2To take the generating set out of the canopy all hose

and cable connections has to be taken off. The set is

fixed to its base by four rubber mountings and can be

taken loos by removing the four nuts from the bolts of

this mountings. Moreover the generating set is fixed

by 2 fail safes that prevents the generating set of

getting loose when the rubber mountings would break

TROUBLE SHOOTING

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.

3 The easiest way to get the generator out of its cap-

sule is by lifting the set with aid of the lifting eyes and

take away the capsule downwards.

4 The cooler elements are welded to the alternator hou-

sing with silver and cannot be disassembled. How-

ever one can take off the complete alternator hou-

sing.

5 Before the alternator can be taken off one has to take

out the fitting to the heatexchanger to be able to take

off the metal cover. All cables and wiring has to be

taken loose first.

6 The rotor can be taken off by removing the bold 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 10-mm rod of 270 mm length and a

M24x2 bolt.

7 Reassembling the generating set one should take

care for alignment cleaning the surfaces between en-

gine and alternator and tighten the bolds crosswise

and gradually.

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

be cleaned and made free of oil and grease.

9Test the generating set first outside its capsule and

check very carefully for leakages before putting it

back in its enclosure.
