6. Operating Instructions
The ATS unit is designed for automatic operation, but also offers a manual override.
6.1 Automatic Mode
In automatic mode, the ATS unit continuously monitors the utility power supply. In the event of a power outage:
- The ATS detects the loss of utility power.
- After a brief delay (approximately 15 seconds), the ATS sends a start command to the connected generator.
- The generator attempts to start (up to 5 attempts with 5-second pauses). If the generator fails to start, a fault indicator will illuminate.
- Once the generator starts, the ATS waits for a warm-up period (approximately 30 seconds) before transferring the household load to generator power.
- When utility power is restored, the ATS switches the load back to the utility grid and signals the generator to shut down after a cool-down period (approximately 30 seconds).
6.2 Manual Mode
The ATS unit can be manually operated for testing or specific situations. Refer to the control panel for manual switch operation.
6.3 Control Panel Overview
