TIP:
Tips contain information, helpful hints
and/or suggestion for ease of operation of the
motorhome or its components.
gloSSary of termS
AC Electricity - Alternating current also
known as household power.
Air Compressor - Pumps air to and builds
pressure in an air system.
Air Dryer - Cools, lters and dries the air
delivered by compressor.
Air Governor - 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 a 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.
Alternating Current (AC) - A current
that varies periodically in magnitude
and direction. A battery does not deliver
alternating current. Also referred to as
shore power, utility power, inverter power,
generator power, etc.
Ampere (Amp) - The unit of measure
of electron ow 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.
ANSI - American National Standards
Institute.
ASTM - American Society for Testing and
Materials.
Black Water - Term associated with the
sewage holding tank. The toilet drains
directly into this tank.
CCA - Cold Cranking Amperage is the
amount of current a battery can deliver for
30 seconds at 0° F without dropping below a
specied voltage, usually 10.5 Volts DC.
Chassis Battery - Powers chassis 12 Volt
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 that you hook-up to at
campgrounds. It is called city water because
water is pulled from a central source (like in
a city) and not the fresh water tank.
Compressor Load Cycle - The time during
which the compressor is building 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 or
passenger side.
Current - The rate of ow of electricity
or the movement rate of electrons along a
conductor. It is comparable to the ow of
a stream of water. The unit of measure for
current is ampere.
Cut-In Pressure - The pressure level in the
air system supply tank which triggers the
compressor load cycle.
Cut-Out Pressure - The pressure level in
the air system supply tank which triggers the
compressor unload cycle.
Cycle - In a battery, one discharge plus one
recharge equals one cycle.
