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
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.
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
The AGS can also be used to manually start and stop the generator at any time.
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.
