INFORMATION
2.5.2
Engine
The M-SQ27 generating set is based on the Mitsubishi S4S
4 cylinder 4 stroke diesel engine. The engine is indirectly
injected. The engine is water cooled and the cooling liquid
is cooled by a heat exchanger and raw (sea) water. The
heat exchanger and all other parts which are in direct
contact with the raw (sea) water are made of seawater
resistant material like naval brass and copper nickel.
The
engine
has
been
WhisperPower application and is very different from the
standard engine supplied for industrial applications!
2.5.3
Digital Diesel Control system
The standard electrical engine control system is 12 Volt
negative earth, non-earth return (ungrounded) is available
as optional. Check your identification data to determine
which system is applied. The system is designed according
to the "energise to run" system. The Digital Diesel Control
is a very advanced microprocessor based full automatic
system. Besides automatic start the system offers many
monitoring options. See the separate Digital Diesel Control
user's manual (number 50200261).
The microprocessor unit of the Digital Diesel Control is
located in the black box on top of the AC alternator (see
figure 5).
2.5.4
Battery charger
On the engine is an alternator generating 50 Amp 12V. This
current is rectified to charge the battery. The voltage is
regulated at approx. 14.4V.
2.5.5
Alarms and shut down
In case of malfunctioning this will be indicated by the failure
light, details will be shown on the display and 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 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
Monitoring
Refer to the operating of the Digital Diesel Control

2.5.7
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. Stopping the engine is executed by the
solenoid that will shut off.
the
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
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. (See 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 CF, CF-4, CH-4, CI-4 or CI-4
plus.
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
