Xantrex Technology XW POWER SYSTEM XW4024-120/240-60 - Manual (Page 105)

The XW Automatic Generator Start
975-0239-01-01 5–13
This section describes the generator configurations and provides diagrams for connecting
the wiring harness to the generator’s start wiring.
Connecting the Thermostats (optional)
Wires 1, 2, 3, and 4 on the wiring harness can be connected to two thermostats. Wires 1
(yellow) and 2 (gray) are intended for thermostat 1 and wires 3 (orange) and 4 (gray) are
intended for thermostat 2.
These wires connect to 12-volt/24-volt output signals from the thermostats. The XW
Automatic Generator Start will start the generator in response to these signals.
Thermostats can not be programmed using the XW Automatic Generator Start.
For specific information about thermostat wiring and where XW Automatic Generator
Start connections should be made, please consult your thermostat documentation or
contact the thermostat manufacturer.
Connecting an External Shutdown (optional)
The external shutdown input is a 12-volt/24-volt input used to assure that the XW
Automatic Generator Start keeps the generator off under conditions that may be potentially
hazardous. Wire 5 (white/black) and 6 (gray) on the wiring harness are intended for an
external switch or sensor (such as a moisture detector, carbon monoxide detector or coach
running signal) that produces an active high 12-volt or 24-volt output.
Important: You can only change GenType after you have put the system or the XW Automatic
Generator Start into Standby mode. See the XW Inverter/Charger Operation Guide for instructions
on putting the system in Standby Mode.
Important: For an explanation of the terminology used in the following section, refer to
Appendix B of the XW Automatic Generator Start Owner’s Guide. For more information about
XW Automatic Generator Start internal relay activity and timing, see the Automatic Generator
Start Owner’s Guide.
