2.5.4 Battery charger

On the engine is an alternator generating 50 Amp 12V.
This current is rectified
voltage is regulated at 14.2V.

2.5.5 Alarms and shut down

In case of malfunctioning this will be indicated by the fai-
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 exhaust
temperature.
Exhaust temperature too high indicates the 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 necessary an optional longer 8 wire twisted
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 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
1 Specification:
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
5,2 l. Including the oil filter it is 5,7 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 ± 350 Kpa (3,5 kgf/cm2/ 50
psi)(3,5 bar).

2.5.12 Cooling liquid

The engine is cooled by cooling liquid. The capacity of
this system of the Whisper 12 ULTRA is 7,6 litres.
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. 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 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 anti freeze the right mixture has to be cal-
