If your generator battery does not have the required voltage, any 12V or 
24V power source will suit this purpose. If an alternate power source is 
used, the negative of the power source must be connect to the other 
contact of the switch.
Multiple control panels or simple contact closures can be wired to the 
external manual on/off inputs. The Auto Gen Start detects if any of the 
contacts close and will change its operating mode to External Manual On 
or External Manual Off (for more information, see “AGS Mode” on 
page 3–9). The Auto Gen Start turns the generator on or off according to 
these inputs and the resulting operating mode change.
Unlike the Manual On or Manual Off operating modes you can enter by 
using the System Control Panel, the External Manual On and External 
Manual Off states are not affected by maximum generator run time (see 
“Max Run Time” on page 3–29).
Connecting an external on/off LED
Wires 9 (White/Blue) and 11 (Black) on the wiring harness can be 
connected to an LED or other light to accompany a remote external on/off 
switch. This light turns on when the generator run signal is active to 
visually indicate that the generator is running.

Important::
With some generators, the generator run signal becomes active
during the preheat stage, before the generator is actually running. In this case, the 
external on/off LED (and the Generator On light on the Auto Gen Start) will turn 
on during the preheat stage and remain on when the generator is running.
For some generators, these lights will also remain on for a period of time after the 
generator has stopped.
