AUTOMATIC STARTING AND STOPPING

3.5.1

General

WhisperPower cannot  be  held  responsible  for
damage  caused  by  the genverter running
unattended  using  the  auto-start/stop  mode  or
interval mode.
Using  the  auto-start/stop  or  interval  mode,  the
genverter may 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.
Included in the delivery are warning stickers to be
applied on several parts of the electric installation
(transfer  switch,  distribution  box, etc.)  to  warn
against  possible  automatic  starting  of  the
genverter.

The WhisperPower Digital Diesel Control system offers several
options for automatic starting and stopping. This menu as well
as other DDC menus may be locked. For unlocking and setting
these options, refer to the APPENDIX of the DDC user’s manual.

3.5.2

Start/stop by external switch

At the back of the DDC remote control panel (40209102), you
will have the possibility to connect two wires in order to allow
the genverter being started by an external signal. This requires
the optional 12-pole green connector ( part no. 50209119).
Two common options are shown in Figure 23, where the signal
can be provided by an external relay or by the Whisper Battery
Monitor (WBM).

Figure 23: Connection for start/stop by external signal

Another possibility is to monitor the voltage of a second battery
(not  being  the  starter  battery)  and  to  start  the genverter
automatically  when  this  voltage  drops  below  a  set  value. This

second  battery  is  often  called  “auxiliary  battery”  or  “service
battery”. It is referred to as BAT2 in the DDC menus. A sense
wire to monitor the second battery should be connected (check
polarity!)  to  the  connector  on  the  back  of  the  remote  panel
(Figure 21). The sense wires must be connected directly to the
second battery and be protected by a 3A fuse.

Settings:

For  settings  other  than  the  factory  settings,  refer  to

the DDC user’s manual, especially to the APPENDIX.

3.6

STARTER BATTERY

For starting, the genverter requires a 12V starter battery of at
least 55 Ah (80 Ah recommended).
The genverter can be connected to the main engine battery or
have  its  own  battery. We  strongly  recommend  the  use  of  a
separate  battery  for  the genverter and  keeping the  wiring
system for the car engine and the domestic DC supply system
completely  separate  and  individually  connected  to  separate
batteries.
However,  the  negatives of  all  the  batteries  on  the  vehicle
should  be  interconnected  to  avoid  difference  in  the  voltage
level  of  the  earth  on  different  places  causing  trouble  to
electronic devices which might be in the system.
The above recommendation is not valid for vehicles having the
starter  battery  of  the vehicle engine  or  other  auxiliary
equipment positive grounded. When this is the case an expert
should be consulted.
The starter battery is charged by the alternator on the engine.
However,  when  the  genverter  is  not  used  for  an  extended
period  of  time,  its  control  system  may  eventually  drain  the
starter  battery.  The  WhisperPower  catalogue  (check

www.whisperpower.com

)  offers  several  solutions  to  prevent

this from happening:

A battery switch may be installed to interrupt the positive
connection.

An AC-supplied battery charger may also help to keep the
battery in good condition when the genverter is not used
(see also battery installation kit).

WhisperPower also offers high efficiency battery charging
units which are able  to  charge  both  the vehicles’s main
battery and the starter battery.

3.7

OTHER RECOMMENDATIONS AND WARNINGS

The battery should be secured for poor road conditions and the
terminals should be insulated. For extra safety the battery can
be  enclosed  in  a  wooden,  plastic,  fiberglass etc.  (non  metal)
box. Even when the earth return system is applied a  negative
battery cable should be used and the vehicle should not to be
used as a conductor.
The battery cables are supplied in a standard length of 1.5 m. If
longer cables are required a larger cross sectional area should
be considered to compensate for voltage reduction.
