4.2.2 STATUS LED Indicator
Flashing Green
– Indicates that the AGS system is initiating a
generator start sequence. This can happen based on two conditions,
either: 1) The
TEST
switch (on the controller or remote switch) has
been pressed and released; or, 2) The remote switch has been set
to the
ENABLE
position and the
START TEMP °F
setting and/or the
START VOLTS DC
setting has been reached.
Solid Green
– Indicates the generator has started successfully and
is providing the required run sense voltage to Terminals 2 (+) and
4 (–) of the AGS.
Solid Red
– This is a fault condition to indicate that the generator
has not provided a correct run sense voltage to Terminals 2 (+) and
4 (–) of the AGS controller after four start attempts.
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 ventilation. Carbon monoxide, an odorless,
colorless, deadly gas may accumulate and cause serious
injury or death.
