Introduction
Functions
Generator Starting Triggers
The AGS can automatically start a generator in response to:
• a low battery voltage,
• large AC loads when inverter is operating,
• a thermostat signal, or
• a pre-programmed exercise period at a specified time of day.
Generator Stopping Triggers
The AGS 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),
• reduction in AC loads when inverter is operating,
• a thermostat signal, or
• a pre-programmed quiet time period.
The AGS can also be used to manually start and stop the generator at any
time.
Programmable Features
Quiet Time The AGS 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
AGS 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 AGS 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 Xanbus System Control Panel (SCP).
Installation Options
The AGS can be installed with an external shutdown input, a manual
generator ON/OFF switch, and an external ON/OFF indicator light.
