Generator Auto Start Requirements and Types
B–2 975-0082-01-01
Recommended Features
In order for the generator to be automatically started by the Auto Gen
Start, 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 Auto Gen Start 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 2–10 to page 2–25.
Note: For overcurrent protection guidelines that apply to the wiring types
discussed in this appendix, see page 2–6.
