Automatic Transfer Switch (ATS)
Your motorhome is equipped with an Automatic Transfer Switch. The ATS is microproces-
sor controlled and will automatically detect which power source is being used (generator
or shore power) and allow power from that connection only. You will not have to plug and
unplug power to the coach if you decide to run the generator.
If you plug into shore power, the ATS will pass power to the motorhome. If the generator
is started, it will override the shore power input (called generator dominant) and supply the
RV with electrical power from the generator. When the generator is shut down, shore power
is restored.
There may be a slight icker of the lights when the ATS changes over from one to the other,
but there is no real interruption of power.
The ATS will disconnect from shore power completely if the power coming in is not high
enough quality (i.e. either low/high voltage, or low/high frequency).
When the generator is operating, it powers the inverter/charger which in turn functions as a
multi-stage battery charger to charge the house auxiliary and chassis batteries.
Refer to and follow safety information found in the manufacturer’s troubleshooting guide
found in your warranty packet
The (diesel or gas powered) generator requires 12-volt power
from the house auxiliary batteries to start, and draws (diesel or gas) fuel to
operate from the chassis fuel tank. If the fuel level in the chassis fuel tank
drops to or below ¼ full, the generator will automatically shut “off” and can-
not be re-started until the fuel tank is lled to above ¼ full.
120-Volt Circuit Breakers
The 120-volt AC circuit breakers located inside the load center protect all 120-volt wiring
and components from circuit overloads and short circuits. Should a circuit overload or short
circuit occur the circuit breaker protecting the aected circuit will “trip” preventing the ow
of electricity through that circuit.
If a circuit breaker trips, shut o the appliance on that circuit (i.e., power converter, etc.)
and allow the circuit breaker to cool down for a brief period of time. After it cools down,
reset the circuit breaker by moving its lever “o” and then back to the “on” position. If the
circuit breaker re-trips or frequently trips, contact your dealer to have the electrical problem
diagnosed and repaired.
A circuit breaker identication label is permanently attached to the inside surface of the 120-
volt Load Center.
Only replace circuit breakers with those of the same specied type, voltage, and current rat-
ing. Please
contact your dealer for repair assistance when replacing circuit breakers.
Circuit breakers and fuses will not oer complete protection of the electrical
system in the event of power surge or voltage spike.
