By making noncritical features that draw power
temporarily unavailable, powernet management
allows the driver to continue using critical features.
Progressive low voltage disconnect (PLVD) is used
to implement the powernet management feature.
The front reading lamps are designated as house
loads and can be turned back on after being
shutdown by PLVD by pressing on the light or light
switch.
No alarm sounds before basic loads are turned off.
A time delay is implemented for the shutdown and
reactivation of loads to avoid unnecessary cycling
when battery voltage is close to shutdown
thresholds.
Loads disconnected by the PLVD will reconnect
when all of the following conditions are met:
•
keyswitch ON;
•
batteries reach and maintain 12.3 volts for one
minute.
