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 CC, 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 Whisper 6/8 is 2.5 U.S.qts (2.4 l); Whisper 11: 3.7
U.S.qts (3.6 l). Including the oil filter it is 3 U.S.qts (2.9
l); Whisper 11: 4.3 U.S.qts (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 oil as this
may have a detrimental effect on engine performance.

Oil pressure
•
Minimum at idle 49 Kpa (0,5 kgf/cm2 - 7psi).
•
Normal at 3600 rpm between 147 and 490 Kpa
(1,5 up to 5 kgf/cm2 - 21 up to 71 psi).
•
Minimum at 3600 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 Whisper 6-8 is 2.1 U.S.qts (2 litres) and of
the Whisper 11 3.7 U.S.qts (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 13 °F (minus
25°C). Also it protects the engine block against corrosion.
