Appendix A: Generator Auto Start Requirements and Types

Recommended Features

In order for the generator to be automatically started by the AGS, it must include electric start and an automatic choke. An automatic primer system may also be required on natural gas and propane powered generators. The generator should also include remote start ability with accessible remote start terminals or a connector. Protective systems for low oil pressure, over temperature, starter lockout and over crank control are valuable features that will prevent generator damage and increase system reliability. “Two- wire” start generators are highly recommended because of the greater simplicity for automatic starting and because they are intended for remote/ automatic/unattended operation.

Generator Starting Types

The AGS supports three major generator starting types:

•Two wire

•Three-wire “Onan”

•Three-wire automotive

NOTE: The terms “two-wire” and “three-wire” refer only to the minimum number of wires necessary to start the generator. Actual installations will require additional wires to connect to the generator, including the generator run signal (switched B+) wiring, and wiring to an optional external ON/OFF switch. For installation wiring diagrams, see page 15 to page 28.

NOTE: For overcurrent protection guidelines that apply to the wiring types discussed in this appendix, see page 11.
