This section provides guidance on common issues you might encounter with the HAT700B ATS Controller. For complex problems, contact technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on | No power supply; loose wiring; blown fuse. | Check power input connections; verify power source; inspect fuses. |
| ATS not transferring automatically | Controller in Manual mode; incorrect parameters; power source issues (e.g., under/over voltage, frequency). | Switch to Auto mode; verify system type and transfer parameters; check power source quality. |
| Alarm indicator active | Over/under voltage; over/under frequency; loss of phase; over current. | Check LCD for specific alarm message; identify and resolve the fault condition; press Alarm Reset. |
| Communication (RS485) issues | Incorrect wiring; wrong communication settings; faulty cable. | Verify RS485 wiring (B(-), A(+)); check baud rate and parity settings; test cable continuity. |
