12 M-SQ PRO 15/18 kVA
Marine Diesel Generator
The microprocessor unit of the Digital Diesel Control is located
next to the alternator.
2.5.4 Battery charger
On the engine is an alternator generating 40 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.
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 installa-
tion instructions)
The WhisperPower generating sets can be connected to a Whis-
perPower Touch panel. On this panel a complete WhisperPower
system including the generator can be monitored and controlled.
(Refer to the manual of the WhisperPower Touch panel for more
information)
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 transform-
ers 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 main-
tenance 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 not the case. One should not follow
these recommendations. Using the wrong specifica-
tion will cause high oil consumption.
2 Oil viscosity:
We recommend a multigrade oil 10W40.
3 Oil capacity:
Excluding the oil filter the content of lubricating oil capacity is:
6,7 ltr. for SQ-Pro 15 / 7,6 ltr. for SQ-Pro 18. 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.
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).
