Connecting an External Manual ON/OFF Switch (optional)

The external manual ON/OFF inputs (wires 7 and 8 on the wiring harness) are intended for wiring to one or more remote ON/OFF switches for starting and stopping the generator manually. The other contact of the switch should be connected to ground. In order for the XW Automatic Generator Start to be able to detect these switches, wire the positive of the generator battery to the constant 12-volt/24-volt generator battery positive (wire 10 on the XW Automatic Generator Start wiring harness). See Figure 5-7.

If the generator battery does not have the required voltage, any 12-volt or 24-volt power source will suit this purpose. If an alternate power source is used, the negative of the power source must be connect to the other contact of the switch.

CAUTION: Equipment Damage

Do not connect the XW Automatic Generator Start to a 48-volt battery bank. The XW Automatic Generator Start is limited to a 30V open-circuit maximum by its regulatory approval and cannot be connected to a 48-volt power source.

Furthermore, tapping 12-volts or 24-volts from a 48-volt battery bank will unevenly wear out the batteries and shortens the battery bank life.

Multiple control panels or simple contact closures can be wired to the external manual ON/OFF inputs. The XW Automatic Generator Start detects if any of the contacts close and will change its operating mode to External Manual On or External Manual Off (for more information, see the XW Automatic Generator Start Owner’s Guide). The XW Automatic Generator Start turns the generator on or off according to these inputs and the resulting operating mode change.

The External Manual On and External Manual Off states are not affected by maximum generator run time. See the XW Automatic Generator Start Owner’s Guide for additional information.
