Starting the Generator
AGS (Automatic Generator Start)
The Magnum® Standalone AGS system monitors your battery system or surrounding
temperature and starts the generator when the battery requires charging or power is needed
to run the air conditioner. The AGS system uses a remote switch setup and does not use
the standalone switch provided with the Magnum® system. The AGS startup switches are
typically located on a command center panel.
Manual Generator function
To start the generator manually, make sure the parking brake is engaged.
The ENABLE button is not used for manually starting the generator.
Press the START button until the generator fires, and the indicator light comes on.
To stop the generator, press the STOP button.
AGS Controller
The AGS controller is typically located in a bathroom cabinet, and
is used to set the run time hours, start temperature, start voltage,
clock and the quiet time. For information on setting these controls,
refer to the Magnum® AGS owner manual.
Automatic Generator Function
Before using the AGS system set the motor home parking
brake.
1.
Press the momentary AGS ENABLE switch. The LED
indicator above the switch will light.
2.
STATUS indicator will display one of three indications:
Blinking Green
– Indicates the system is initiating
a generator start sequence (either the TEST or
ENABLE switch has been pressed).
Solid Green
– Generator has started successfully.
Solid Red
– After 4 attempts to start, there was
a “no start” indicating a problem with the AGS
system.
3.
A generator “START/STOP” switch is installed on the
command center panel. A second switch is located on the generator, and depending on
your model, there may also be a switch installed on the dash.
4.
At either “START/STOP” switch, press and hold the upper portion of the switch to start
the generator. Depending on the outside temperature, the start process can take up to 15
Maintenance
During periods of extended storage:
1.
Add a diesel fuel additive to the chassis fuel tank to prevent algae growth.
2.
Completely fill the chassis diesel fuel tank to prevent water condensation and rust in
the tank.
3.
Cover the end of the generator exhaust pipe with screen to prevent bug and rodent
intrusion.
With the exception of simple items, such as normal maintenance (i.e., oil changes, etc.),
all service work should be done by an authorized repair facility. Improper adjustments can
damage the generator and electrical appliances and can result in a safety hazard. Follow the
generator owner’s manual for maintenance intervals and recommendations.
Exercising Your Generator
– When storing the generator for extended periods of time, it
is important to run the generator regularly to keep everything in good working order. Lack
of exercise can cause moisture build-up in the fuel system resulting in poor performance.
For more information on generator operation and maintenance, refer to the generator owner’s
manual.
Excessive usage can overheat and damage the generator starter motor. Do not
engage the starter motor for more than 20 seconds at a time. If the generator
doesn’t start after the first attempt, wait at least two minutes before beginning
another start sequence. If the generator does not start after a third attempt,
refer to the generator owner’s manual for additional information.
