General Operating Procedure
Your generator can be started and stopped from the inte-
gral control panel on the generator, or from the optional
remote control panels or switches located inside the
motorhome. Outlined here are the simple steps for starting
and stopping the generator:
• Before starting the generator, turn OFF air conditioners
and large electrical loads.
• Before starting in cold weather, turn OFF all appliances
for best long-term performance.
TO START:
1. Locate the Generator ON/OFF switch, on the Monitor
Panel or integrated into the multiplex control panel.
2. Prime the engine by holding the OFF position of the
start/stop switch for a few seconds. e LED on the
switch will turn on.
3. Aer priming, press and hold the ON position until
you hear the generator start. e LED will ash during
starting and then remain on when the generator is run-
ning. Release the switch when the LED stops ashing.
a. e 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 appli-
ance (microwave’s clock) indicates the generator is
supplying electricity.
Under normal operating conditions, you may detect the
engine of the generator increase and decrease in RPM (run
faster and slower). is is normal and due to changes in
electrical power demand.
TO STOP:
Turn OFF air conditioners and large electrical loads and
allow the generator to run for 3-5 minutes before stopping,
to allow the generator to cool down. Press and hold the
OFF switch position until the generator stops. e indica-
tor LED on the generator switch will turn o.
NOTE:
• Control switches for operating the generator are
located on the monitor panel or, if equipped, on
the multiplex touch-screen panel.
• Your motorhome’s generator may be equipped
with features that prevent operation if certain
maintenance parameters are not met, i.e., low
engine oil level, clogged air and fuel filters, etc.
• 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.
• 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.
• 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)
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. e 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 sucient amount of charge, the AGS will
automatically turn o 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 condi-
tioner to operate. e AGS will automatically turn o
the generator aer the air conditioner turns o.
• Some units are time-programmable, enabling the user
to determine when the generator will operate. is
feature is useful if the campground has restrictions
regarding running generators during certain time
periods of the night.
• Some units may also have ‘shore power sense’, so that
when shore power is connected, the AGS system will
place the generator in a stand-by mode, only allowing
the generator to operate if electrical demand cannot be
fullled by shore power alone.
