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 Xantrex XW
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 Xantrex XW 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 2–10
to page 2–23.
Note: For overcurrent protection guidelines that apply to the wiring
types discussed in this appendix, see page 2–5.
