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
helps 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 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
9 l. Including the oil filter it is 9.3 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).
• At 2230 rpm ±300 kPa (3 kgf/cm²/45 psi) (3 bar).
2.5.13 Cooling liquid
The engine is cooled by cooling liquid. The capacity of this
system depends on the size of the radiator piping and
other parts in 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 to 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.
Additional filling of engine cooling system has to be done
via the expansion tank. 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 connection can be used to connect an
open hose to drain the overflow of the cooling liquid to
outside the vehicle.
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.
The cooling liquid in the engine is pressurised. A high
pressure hose connects the manifold to the expansion
tank.
