Functions
Generator
Starting
Triggers The XW Auto Generator Start can automatically start a generator in
response to:
• low battery voltage
• high battery drain from the AC loads
• a thermostat signal
• a pre-programmed exercise period at a specified time of day.
Generator
Stopping
Triggers The XW Auto Generator Start can automatically stop a generator in
response to:
• the introduction of qualified grid power (grid power within
acceptable parameters)
• high battery voltage
• battery charge stage (float or absorb stage)
• removal of a high battery drain from the AC loads
• a thermostat signal
• a pre-programmed quiet time period
The XW Auto Generator Start can also be used to manually start and stop
the generator at any time.
Programmable
Features Quiet Time The XW Auto Generator Start features a quiet time setting,
which prevents the generator starting at night or during other
inconvenient periods.
Exercise Period During times of prolonged generator inactivity, the
XW Auto Generator Start can be programmed to run (or “exercise”) the
generator for a pre-defined period. This ensures the generator remains
operational and that the starting battery stays charged.
Status
Reporting The XW Auto Generator Start reports its operating mode, its settings,
generator activity, and the reason for generator starts to the Xanbus
system. This information can be viewed on the XW System Control
Panel.
Installation
Options The XW Auto Generator Start can be installed with an external shutdown
input, a manual generator ON/OFF switch, and an external ON/OFF
indicator light.
