Power Control System - Fleetwood Discovery Owner's Manual

Power Control System

Overview:
The Power Control System
(PCS) monitors AC power
consumption. If AC power
consumption exceeds shore power
supply, the system automatically
reduces power consumption by
"shedding" predetermined loads.
The system also monitors AC
voltage and current as well as
polarity. A PCS monitor panel
located on the systems control
panel details operating conditions.
Requirements:
Connect to shore power or
‹
start the generator.
Turn on the battery cutoff
‹
switch.
Operation:
The PCS senses whether it is
connected to 50 Amp or 30 Amp
shore power or if operating from
the generator. When connected to
20 amp shore power, the remote
will need to be changed to 20 amp
service by using the Set button.
Load center located above pilot
The PCS controls operation
of five possible loads to shed.
Shedding a load means removing
power from the load allowing
extra power to operate other loads
of greater importance. These
shed loads are typically heavy
power consuming loads that can
be temporarily postponed until
enough power is available to
safely operate the loads without
the possibility of overloading the
shore power breaker.
Load shed example: If average
current demand exceeds 24 amps
when hooked to a 30 amp service,
the system will automatically shed
load Number 1 to keep average
current demand below 80%
(24 Amps) of the 30 amp shore
service to avoid the possibility
of overloading the shore power
breaker. If shedding load Number
1 is insufficient to avoid tripping
the shore power breaker, the
system will shed load 2 and so on
until current demand, in total, is
within safe operating limits.
The PCS remote will indicate
which loads have been shed.
Repeatedly press the Down arrow
on the remote to display the load
shed list. Any loads that are shed
will automatically be reactivated
when sufficient power is once
again available.
NOTE:
20 amp shore service
mode is not automatically
detected and the operator
must manually set 20 Amp
mode when connected to 20
amp shore power.

Power Share and Reduced
Charging:
Depending on operating
conditions, amperage of shore
power and battery state of charge,
the system may attempt to reduce
battery charging as a way to
conserve AC power during peak
demand or if batteries are of
sufficient charge, the system will
automatically enable the inverter
to help supply extra power during
peak demand periods. These
operating conditions will be
indicated on the remote.
Power Monitoring:
The system monitors voltage
and current as well as polarity
when connected to shore power or
operating from the generator. Refer
to the remote to monitor voltage
and current.
