Generator Auto Start Requirements and Types
B–2 975-0307-01-01
Recommended Features
In order for the generator to be automatically started by the XW Auto
Generator 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 XW Auto Generator 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 2–9 to page 2–25.
Note: For overcurrent protection guidelines that apply to the wiring types
discussed in this appendix, see page 2–5.
