guarded: oil pressure, coolant temperature and alternator
temperature.
Too high alternator temperature indicates the alternator
coolant to be blocked or the pump impeller to be
damaged.
All alarm switches are closed when no malfunction occurs.
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
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)
2.5.8
Hour counter
The remote control offers several timer functions that
helps 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 Mitsubishi engine must
be run on heavy duty lubricating oil meeting the
requirements of API class CD, CF or CF_4.

wire
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
3.7 l. Including the oil filter it is 4.2 l.
Do not overfill with lubricating oil as this may have a
detrimental effect on engine performance

Oil pressure
•
Minimum at idle 98 kPa (1 kgf/cm2 - 14psi) (1
bar).
•
Normal at 1500 rpm ±343 kPa (3.5 kgf/cm2 - 50
psi) (3.5 bar).
2.5.12 Cooling liquid
Both the engine and alternator are cooled by cooling
liquid. The capacity of both systems depend 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. Al so 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 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. The cooling liquid in the alternator is not pressurised.
The alternator's expansion tank has an open connection to
drain liquid and release air.
