stop switch for a few seconds. The LED on the switch will
turn on.
3. After priming, press and hold the ON position until
you hear the generator start. The LED will flash during
starting, then remain on when the generator is running.
a. The engine will turn over and should start within a few
seconds.
b. If the engine fails to start within a few seconds, do not
over-crank.
4. Before turning ON appliances, let the generator warm up
for a few minutes. Generally, a beep from an appliance
indicates that the generator is supplying electricity.
5. Under normal operating conditions, you may detect the
engine of the generator increase and decrease in RPM
(run faster and slower). This is normal, due to changes in
electrical power demand.
TO STOP:
1. Turn off air conditioners and large electrical loads and
allow the generator to run for 3-5 minutes before stop-
ping, to allow the generator to cool down.
2. Press and hold the OFF switch position until the generator
stops. The indicator LED on the switch will turn off.
NOTES:
• To prevent generator overload due to initial start-
up current demand, turn ON air conditioners and
appliances in a sequential order and only after the
generator is started and runs for a few minutes.
• If you lose power to the motorhome while op-
erating the generator, check the overload circuit
breaker on the generator; it may have tripped due
to too much power demand. Turn off some appli-
ances or electrical devices in order to reduce the
total power demand.
• If your generator fails to start or remain running,
and there is an adequate fuel supply and 12 volts
DC present, it may need maintenance attention.
Refer to the manufacturer’s owner’s manual for
troubleshooting and maintenance procedures.
• Turn OFF all appliances before resetting a tripped
circuit breaker. If the breaker trips again with all
electrical loads off, turn OFF the generator and
contact a qualified technician for repairs.
• If your motorhome is supplied with an AGS sys-
tem, refer to your motorhome’s Owner’s Packet
for details regarding its features, set-up program-
ming, and operation.
• If your motorhome has a multiplex wiring system,
settings for the automatic generator start system
are incorporated in the Settings Menu of the mul-
tiplex system.
• For complete generator instructions, refer to
the manufacturer’s guidelines included in your
Owner’s Packet, or available through your TMC
Owners Resource account, or available from the
manufacturer’s website.
Automatic Generator Start (AGS)
Disable the AGS system when sleeping in the
motorhome or when the motorhome is parked in a
garage or confined space. The potential of carbon
monoxide poisoning is present when the generator is
operating.
DANGER DANGER
Your motorhome may be equipped with an Automatic
Generator Start (AGS) system. An AGS can be a stand-alone
system, part of the generator’s control circuitry, or part of the
inverter’s control system. The purpose of an AGS system is
to automatically start (and run) the generator when certain
programmed parameters are encountered:
• When the auxiliary battery(ies) voltage drops to a pre-
determined level, the AGS circuitry will sense the low
voltage condition and start the generator, which, in turn,
supplies charging voltage to the batteries through the
inverter/charger. Once the system batteries have regained
a sufficient amount of charge, the AGS will automatically
turn off the generator.
• When there is a power demand from air conditioners,
some models may feature a thermostat interface, where if
the temperature of the coach rises to a programmed level,
the generator will start, allowing the air conditioner to
operate. The AGS will automatically turn off the generator
after the air conditioner turns off.
• Some units are time-programmable, enabling the user to
determine when the generator will operate. This feature is
useful if the campground has restrictions regarding run-
ning generators during certain time periods of the night.
• Motorhomes equipped with a 12 volt DC compressor -
type refrigerator are typically outfitted with a stand-alone
AGS. When turned ON, the AGS will automatically start
the generator when the auxiliary battery(ies) drop to a
programmed voltage level, therefore, keeping the refrig-
erator operational.
