1. Inleiding
The SmartGen HAT360 series dual power automatic transfer switch (ATS) controller, including models HAT361 and HAT361C, is designed with a microprocessor core for precise monitoring and control of dual power systems. It accurately measures two-way voltages, detects abnormalities (such as over/under voltage, over/under frequency, loss of phase, and reverse phase sequence), and intelligently manages the transfer between power sources. This controller integrates an LCD display and digital communication capabilities, providing a user-friendly interface for efficient power management.
The HAT361C model includes RS485 communication for remote control and monitoring via Modbus protocol.

5.4 Bedrijfsmodi
5.4.1 Handmatige modus
To enter Manual Mode, press the Handmatig key. The manual status indicator will illuminate. In this mode, you can manually control the S1 and S2 breakers:
- S1 Close: If the load is open, S1 closes and supplies power to the load.
- S2 Close: If the load is open, S2 closes and supplies power to the load.
- Open: Disconnects the load from both power sources.
5.4.2 Automatische modus
To enter Auto Mode, press the Auto key. The auto status indicator will illuminate. In Auto Mode, the controller automatically transfers the switch based on the status of S1 and S2 power, transfer priority, and auto transfer/restore settings to ensure continuous power supply to the load.

7. Onderhoud
To ensure the longevity and reliable operation of your SmartGen ATS controller, follow these general maintenance guidelines:
- **Regular Inspection**: Periodically check the controller for any visible damage, loose connections, or signs of overheating.
- **Cleaning**: Keep the controller's front panel and ventilation openings clean and free of dust. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
- **Firmware-updates**: Controleer de firmware van de fabrikant website for any available firmware updates. Follow the instructions carefully if performing an update.
- **Environmental Conditions**: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent premature component failure.
- **Wiring Integrity**: Annually inspect all wiring connections for tightness and corrosion. Loose connections can lead to intermittent operation or damage.
8. Probleemoplossing
If you encounter issues with your HAT361/HAT361C controller, consider the following general troubleshooting steps:
- **No Power/Display Off**: Check the power supply to the controller. Ensure all power input terminals are correctly wired and receiving the specified voltage.
- **No Automatic Transfer**: Verify that the controller is in 'Auto Mode'. Check the status of S1 and S2 power sources on the display. Ensure all abnormal conditions (over/under voltage, frequency) are cleared. Review the wiring for S1/S2 voltage inputs and breaker control outputs.
- **Manual Operation Fails**: Ensure the controller is in 'Manual Mode'. Check the wiring to the S1/S2 close and open outputs.
- **Alarm Indicator On**: Check the LCD display for specific alarm messages. Refer to the 'Indicator Display' section for common alarm meanings. Address the underlying issue (e.g., voltage abnormality, frequency deviation).
- **Communication Issues (HAT361C)**: Verify RS485 wiring (A+, B-, GND) is correct and secure. Ensure the 120Ω matching resistor is properly connected if required by your setup. Check communication settings (baud rate, parity) on both the controller and the connected device.
- **Incorrect Readings**: Confirm that the voltage and current transformer ratios (if applicable) are correctly configured in the controller's settings.
If the problem persists after performing these checks, contact technical support.
9. Gebruikerstips
- **Parameter Configuration**: Take time to properly configure all parameters, especially voltage and frequency thresholds, to match your specific power system requirements.
- **Test Regularly**: Periodically test the automatic transfer function to ensure the system operates as expected during a power outage.
- **Backup Settings**: If possible, record or back up your controller's configuration settings for quick restoration in case of a reset or replacement.
- **Environmental Protection**: While the front panel is IP40 rated, ensure the overall installation protects the controller from excessive dust and moisture, especially the rear terminals.
