AC Electricity - Alternating current also known as household power.
Air Compressor - A device that pumps air to and builds air pressure in an
air system.
Air Dryer - A device that cools, filters and dries the air delivered by an air
compressor.
Air Governor - A device that controls the operation of the air compressor by
constantly monitoring air pressure in the supply tank of the air system.
The air governor initiates the unload cycle when the cut-out pressure is
reached. The air governor also controls the air dryer by sending an air
signal ( at the beginning of the compressor unload cycle ) to the control
port of the air dryer, initiating the purge cycle. When this air signal is
removed by the governor ( at the beginning of the compressor load
cycle) the purge valve closes and the drying cycle begins.
Ampere (Amp) - The unit of measure of electron flow rate of current
through a circuit.
Ampere-hour (Amp-hr. AH) - A unit of measure for a battery electrical
storage capacity, obtained by multiplying the current in amperes by the
time in hours of discharge. (Example: a battery which delivers 5
amperes for 20 hours, delivers 5 amperes times 20 hours, or 100 Amp-
Hr. of capacity.)
Black Water - Term associated with the sewage holding tank. The toilet
drains directly into this tank.
Chassis Battery - Powers chassis 12V accessories and starts engine.
Circuit - An electric circuit is the path of an electric current. A closed circuit
has a complete path. An open circuit has a broken or disconnected path.
City Water - A term associated with the water supply available for hook-up
when you are at campgrounds. It is called city water because water is
pulled water from a central source (like in a city) and not the fresh
water tank.
Compressor Load Cycle - The time during which the air compressor is
building air pressure in an air system.
Compressor Unload Cycle - The time during which the air compressor is
idling and is not building air pressure in an air system.
Curbside - This refers to the side of the motorhome which faces the curb
when it is parked. Often called the door side.
