operation with the remaining power in the battery. In the
off
position the battery voltage will drop to
roughly 8–8.5 volts DC before the inverter will shut down.
Bat Capacity:
This mode allows the user to input the battery bank size in amp hours. This custom
tailors the charger’s decision-making as to what charge rate to use. See the section on batteries
for more information. See the RC7 Menu Map on page 34 for all available settings. An “Auto”
setting is provided which automatically determines the optimum charge rate for the battery bank
capacity. The RC7 will require several charge/discharge cycles to optimize this parameter. The
“Auto” setting is the default.
Battery Type:
Sets the type of batteries being used in the system. Either
gel cell
or
liquid lead
acid
may be selected. See the section on batteries for more information on battery types and
charging methods. If you have questions about a specific battery type or don’t know what type of
batteries you have consult the battery manufacturer or a dealer.
Charge Rate:
Menu allows the user to set the charger’s output as a percentage of its maximum
capability. This limits the amount of current that the charger may draw, leaving that current
available to power loads. This setting is available so that small battery banks will not be charged
at too high a charge rate.
VAC Dropout:
Sets the minimum voltage that may be present before the unit switches from
charger to inverter mode. It is adjustable from 40 to 105 VAC. For example: The VAC dropout
default is set at 40 volts AC. When the AC input voltage drops to 40 volts, the inverter will switch
from charge mode to inverter mode. This protects AC loads from utility outages.
Shore Pwr Amps:
This mode adjusts the maximum power that may be drawn through the
shorepower cord. This is a safety feature since the inverter may be capable of drawing more
power through the shore cord than the cord is rated for. Care should be taken when choosing this
setting since a shorepower setting that is too low will cause a shutdown if the loads exceed the
shorepower
limit. The RV series is not designed to add power from the batteries to make up for
the low shorepower capacity. The unit can either invert or pass AC power but cannot mix the
inverted power with the shorepower.
RC7 Setup:
Allows adjustment of the RC7’s display. Three modes are available. The
Last Key
mode leaves the screen on the RC7 where it was when last used.
Power Saver
mode turns the
RC7 off after five minutes with no key press, conserving energy. Selecting the
Rolling Display
mode causes the display to cycle through the user menu one item at a time for an indefinite period
until a key is pressed.
LCD Contrast:
This menu allows adjustment of the LCD display’s contrast.
Two Fuel Gauges:
This menu allows selection of two fuel gauges when two RV series units are
working together. The selections in the menu also allow the user to select which RC7 remote
control will be the master fuel gauge display if two RC7s are being used. The default is one fuel
gauge only.
Fuel Gauge Cutout:
Selects the voltage scale on which the RC7 will base the empty and full
reading of the fuel gauge. For example: the default setting of 9.5 VDC = 0% SOC (State of
Charge) will cause the RC7 to register an empty indication when the battery voltage drops to 9.5
VDC.
