Digital Diesel Control System 12 Volt - Mastervolt whisper 3,5 Installation Manual

1.4.4 Digital Diesel Control system (12 Volt)
1 DIGITAL DIESEL CONTROL SYSTEM
The electrical control system is standard in 12 Volt
with negative earth. Non- earth return is available as
an option for aluminium vessels to prevent corrosion.
All electrical wiring has been prepared on the genera-
ting set to the control panel prior to despatch from the
factory. The engine is controlled by a very advanced
microprocessor based system: Digital Diesel Control.
The "black box" containing the microprocessor is
located on top of the alternator.
A local control panel is on the generating set.
Remote control
A remote control
microprocessor is in the delivery. A 15 m intermediate
8-pole cross-wired communication cable is in the
standard supply too. If necessary an optional longer
(max 30 m) intermediate cable can be connected if
the standard length does not suit the required
distance. When a longer distance than 30 m is
required, consult the Mastervolt service department
for advice. Refer to fig. 11.
Fig. 11.
One can mount the control panel after drilling a hole
in the dashboard using the plastic cover. Refer to the
dimensional drawing in paragraph 3.5. The panel
without the plastic cover fits the Mastervision modular
panel system.
More remote control panels (slave panels) can be put
in parallel by using the modular connectors on the
back of the units. As a slave one can use the same
panel offering all functions again. It is also possible to
use an old or new type slave panel only to start and
stop the generator.
Old type remote panels and system panels can be
connected by means of the green connector.

Pay attention to the colour codes as indicated in fig.
12 when fitting cable to the green connector. Some
software versions in old system panels (supplied
before may 2004) could conflict with the software in
the DDC and an up-date of the software of the
system panel could be necessary. When this is the
case consult to the Mastervolt service department for
advice.
When using the factory settings, installation is very
simple: just plug the remote cable into the remote and
the generator is ready to use. Refer to fig. 12.

Acoustic alarm or warning lamp
One can connect an external max.150 mAmp relay to
generate an acoustic warning or applying a warning
lamp etc. Be aware of polarity as some relays has a
diode inside and should be connected plus to plus en
minus to minus as indicated. Refer to fig. 12.

damage caused by the unattended running
generator using the auto-start/stop mode or
interval mode.
Using the auto-start/stop (interval) mode the
generator can start unexpectedly. When working
on the electrical system, the 3 Amp fuse must be
removed from the control panel and the battery
plus cable must be removed from the battery.
The Mastervolt Digital Diesel Control system offers
several options for automatic starting and stopping.
