THEORY OF OPERATION

System

The AGS system, when in AUTO or AUTO QUIET TIME mode, continuously monitors the house battery and two air conditioning/heater thermostats.

If the LOCAL TIME of day is not within the AUTO QUIET TIME window, it will start the generator to charge the battery or to cool or heat as required.

The AGS system is invisible to the normal operation of the auxiliary generator manual start and stop controls with the following exceptions:

1.If the generator is started by the AGS, which is in AUTO or AUTO QUIET TIME mode, the selection of OFF at the AGS Remote Panel will stop the auxiliary generator.

2.If the AGS system commands the generator to start and it does, the AGS system will stop the generator at the appropriate time. If the generator stops for some other reason, even if it is turned Off by a manual switch other than the AGS, the AGS system will assume that there is a FAULT. It will turn itself OFF and turn on the GEN FAULT light. At this point, the AGS system must be turned on to the AUTO mode or AUTO QUIET TIME mode for it to resume control of the generator.

Once started by the AGS system, the generator will run for a minimum of two hours. This will ensure that there is a good charge in the battery, although it may not be fully charged at the end of the cycle. If the battery voltage does not reach

13.5volts during the two-hour period, the generator will continue to run for an additional two hours. If at the end of the second two-hour period the battery voltage is still not up to 13.5 volts, then the AGS systems assumes that there is a problem and turns the generator OFF. It must be restarted manually.
