INSTALLATION
2.4.4 Electric installation (12 Volt)
1 DIGITAL DIESEL CONTROL SYSTEM
The electrical control system is standard in 12 Volt
with negative earth. Non-earth (ungrounded) return is
available as an option. All electrical wiring has been
prepared on the generating set and to the control
panel prior to despatch from the factory.
Remote control
A remote control panel also containing a
microprocessor is in the delivery. A 15 m intermediate
8-pole 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.
21.
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. 22.
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. 22.
Automatic start/stop
Mastervolt cannot be held responsible for
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.
Access to this menu and other menus could be
blocked. For blocking and setting up this options refer
to the APPENDIX of the DDC users manual.
One of these options is to monitor a second battery
(Not being the starter battery) to start the generator
automatically when the voltage of this battery drops
below a certain setting.
Other names for this second battery are “auxiliary
battery”, “service battery”, ”users battery” or
