Whisper Power W-SQ 27 kVA / 25 kW Installation Manual page 13

Multiple 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.
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 Figure 23.

Acoustic alarm or warning lamp
One can connect an external max.150 mA relay to generate an
acoustic warning or applying a warning lamp etc. Be aware of
polarity as some relays have a diode inside and should be
connected plus to plus en minus to minus as indicated. Refer to
Figure 23.
Connection for emergency stop / fire alarm switch
The generator has an emergency stop button. In order to stop
the generator automatically in case of a fire alarm, you can use
the bypass connection between fastons J7 and J18 on the
backside of the local control panel (Figure 24). To do so, remove
this bypass connection and then replace it by a potential-free
fire alarm switch with normally closed contacts.

Automatic starting and stopping
WhisperPower 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 WhisperPower Digital Diesel Control system offers several
options for automatic starting and stopping. Access to this
menu and other menus may be blocked. For de-blocking and
setting up this options refer to the APPENDIX of the DDC user's
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 "consumers battery". We
will refer to this battery as "the second battery"(BAT2). In some
menus the starter battery could be indicated as "the first
battery" (BAT1).
A sense wire to monitor the second battery should be
connected (attention polarity!) to the connector on the back of
the remote panel. Refer to Figure 23. The sense wires must be
connected directly on the second battery before a main switch
and be protected by a 3 Amps fuse.
(Monitoring the generator starter battery does not require an
extra sense connection)
Settings
When choosing other settings than the factory settings, refer to
