Operation
4.3.1 Operational Notes
• To manually stop the generator during the run time cycle, simply press
the remote switch to the OFF position.
• If a fault condition occurs, press the AGS switch to OFF and then back
to the ENABLE or TEST position. If the problem persists, refer to the
Troubleshooting section in this manual.
• When the AGS switch is placed in the OFF position, all AGS generator
start functions are disabled. The STATUS indicator is also off when the
switch is in this position.
• Once the generator has completed the RUN TIME HOURS the AGS im-
mediately begins to monitor the START TEMP °F and START VOLTS DC
settings for the next auto start cycle.
• It is recommended that the AGS remote switch be set to the OFF position
if the connected generator is placed into storage or left unattended for
extended lengths of time.
• If using the temperature start feature in an RV coach, set the air condi-
tioner thermostat to match the START TEMP °F setting. If using two air
conditioners, it is suggested that the second air conditioner thermostat
be set 2°-5° higher than the fi rst air conditioner. This staggered setting
allows the fi rst air conditioner to start and run in an effort to keep the
coach cool. If the temperature continues to rise inside the coach, the
second air conditioner turns on to further cool the coach.
• When the generator starts successfully, the STATUS indicator turns solid
green. The generator runs until the RUN TIME HOURS setting is reached,
at which time a stop signal is sent to the generator.
• If the generator is running when the switch is pushed to the TEST posi-
tion, the generator stops and then starts again. The generator then runs
for approximately 30 seconds before shutting off.
• There is a two minute delay before the AGS attempts to start the generator
if the voltage to the AGS controller falls to the START VOLTS DC setting.
There is no delay if the AGS attempts to start the generator when the
temperature around the remote switch rises to the START TEMP °F setting.
4.3 AGS System Operation
When the AGS is enabled and has determined that a low battery and/or a high
temperature condition exists, it attempts an automatic generator start. This is
done by closing its internal relays (based on the GEN TYPE selection) to control
the starter much like a person does when manually starting the generator.
The starter is turned on for short periods of time and then turned off. If the
AGS determines that the engine has started while cranking (indicated by a
solid green STATUS indicator), the starter is turned off after a short delay.
If the engine does not start, another attempt to turn on the starter is made
after a long delay period. This is repeated until either the generator starts or
the maximum number of start attempts is reached, which causes the AGS to
go into a fault condition (indicated by a solid red STATUS indicator).
WARNING: Never allow the generator to start/run in an enclosed
garage or any other type of enclosed structure without proper ven-
tilation. Carbon Monoxide, an odorless, colorless, deadly gas may
accumulate and cause serious injury or death.
