Airstream 1980 Argosy Owner's Manual page 67

The optional Solid State Central Control
Panel, with dig~tal clock used in Excella II
models is located above the refrigerator and
refrigerator cabinet. The control panel without
digital clock used as an option in International
and Argosy models is located in the rooflocker
above the refrigerator. Both panels conta~n the
necessary instrumentation to monitor your
trailer's systems.
The panel display button lights up the diode
indicator lights. The AC power light indicates
that you are operating on 120V AC.
The battery condition tester lights indicate
whether the trailer batteries are in good, fair,
weak or bad condition. When they show weak
or bad condition, you should take every
reasonable step to conserve power by using as
few lights as possible and switching off
appliances. The battery should be charged as
soon as practical with the tow vehicle charging
system or by connection to 120 volt power.
The charging system in your trailer is much like
the charging system in your car. The unlvolt
package performs a similar function to the car
alternator by constantly recharging your battery
as power is used. It is important to remember,
however, that if the total current draw is greater
than the univolt's capacity to recharge, your
battery may become discharged even though
the univolt is attempting to keep it charged. In
this event, it will be necessary to reduce current
usage.

The LP monitoring gauges on the Excella II
panels show the amount of LP gas in your
bottles.
The water pump switch, when on, also lights
the indicator light. On trailers without a Central
Control Panel, this switch is located in the
galley area. For a complete discussion of the
pump, please refer to page 83.
