and will start the engine automatically. Pushing the STOP
button will stop the engine and the electrical system will be
deactivated.
2.5.8
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
communication 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)
2.5.9
Hour counter
The remote control offers several timer functions that help
to schedule maintenance.
2.5.10 Load indicator
On the remote control the load will be indicated on the
display and by the LED-bar. The load is measured by
current transformers on the alternator. All phases are
monitored and overload of all phases or just one or two
phases will provoke an alarm or even shut down when the
alarm is ignored.
2.5.11 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.
2.5.12 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, 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 is
5.5 U.S.qts (5.2 l). Including the oil filter it is 6 U.S.qts
(5.7 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

Oil pressure
•
Minimum at idle 98kPa (1 kgf/cm² - 14psi) (1 bar).
•
Normal at 1800 rpm ±350kPa (3.5 kgf/cm² - 50
psi) (3.5 bar).
2.5.13 Cooling liquid
The engine is cooled by cooling liquid. The capacity of this
system of the Whisper 15 ULTRA Three Phase is 8
U.S.qts (7.6 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 to minus 13 °F
(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
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 212°F (100°C). The temperature
switch in the thermostat housing switches at 230°F
(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.
