1. Introduction
The SmartGen HAT560N series ATS controller is an intelligent dual-supply module designed for automatic transfer switch (ATS) applications. It integrates configurable functions, automatic measurement, an LCD display, and digital communication capabilities. This controller combines digital, intelligence, and networking technologies to provide precise control and reduce operational errors, making it an ideal solution for various ATS systems.
Equipped with a powerful microprocessor, the unit accurately measures 2-way 3-phase/single-phase voltage and frequency. It provides digital output signals for abnormal conditions such as over/under voltage, over/under frequency, loss of phase, and reverse phase sequence. The HAT560N series is suitable for specialized ATS, Contactor ATS, and Air break ATS, offering a compact structure, advanced circuits, simple wiring, and high reliability. It is widely applicable in electrical devices, automatic control, and testing systems across industries like electric power, telecommunications, petroleum, coal, metallurgy, railways, municipal administration, and intelligent buildings.

3.2 Wiring Connections
Refer to Figure 2 for the rear panel wiring terminals. The controller uses pluggable terminals for convenient and secure connections. Ensure all connections are made according to the specific application requirements and local electrical codes.
- DC Power Supply: Connect the main DC power supply to terminals B- and B+.
- Auxiliary Outputs: Terminals 1-7 provide auxiliary outputs (e.g., AUX OUTPUT1 (7A), AUX OUTPUT2 (7A), AUX OUTPUT3 (16A), AUX OUTPUT4 (16A)).
- AC Voltage Input: Connect AC voltage inputs for 1# AC Voltage Input (A1, B1, C1, N1) and 2# AC Voltage Input (A2, B2, C2, N2).
- Close Outputs: Terminals for 1# CLOSE OUTPUT (16A) and 2# CLOSE OUTPUT (16A) are available.
- Auxiliary Inputs: Terminals 22-26 are for auxiliary inputs (AUX. INPUT1, AUX. INPUT2, AUX. INPUT3, COM).
- Communication Link: The LINK terminals are used for communication.
3.3 System Type Configuration
The controller supports various system configurations, which can be set during initial setup:
- Mains (1#) & Generator (2#)
- Generator (1#) & Mains (2#)
- Mains (1#) & Mains (2#)
- Generator (1#) & Generator (2#)
The controller can be configured for either an AC or DC system, depending on your application.
4. Operation
4.1 User Interface
The controller features a 132x64 LCD with backlight for clear display of information. Operation is performed via push-buttons. The display supports both Chinese and English languages.
4.2 Operating Modes
The HAT560N/HAT560NB supports two primary operating modes:
- Automatic Mode: The controller automatically manages the transfer between power sources based on configured parameters and detected conditions.
- Manual Mode: Allows manual control to force the switch to close or open, providing flexibility for testing or specific operational needs.
4.3 Parameter Settings
All operational parameters can be configured directly on-site using the controller's interface. A two-level password system ensures that only authorized personnel can modify settings, enhancing security and preventing unauthorized changes.
4.4 Genset Operation Settings
During commissioning, the genset can be configured to operate in either On-load or Off-load mode. The ATS controller also includes an automatic re-closing function for enhanced reliability.
The closing output signal can be configured as either interval-based or continuous output, depending on the requirements of the connected ATS mechanism.
4.5 Neutral Line Configuration
The controller is compatible with various ATS configurations, including those with one neutral position, two neutral positions, or no neutral position. It also supports applications with two isolated neutral lines.
4.6 Scheduled Operations
The controller features a real-time clock (RTC) and supports scheduled start and stop functions for generators. This allows for setting the genset to start once a day, week, or month, with options for both loaded and unloaded operation. It can also manage two generators in a cyclic operation, with configurable running and crank rest times.
4.7 Remote Communication
A standard LINK communication interface is provided, enabling "remote controlling, remote measuring, and remote communication" functions via the ModBus communication protocol. This allows for remote starting/stopping of the genset and remote control of the ATS to close or open. Users can also remotely monitor the controller's current status, including digital input/output ports, and detect conditions like over/under voltage and frequency.
5. Maintenance
Regular maintenance ensures the longevity and reliable operation of your ATS controller.
- Keep Clean: Periodically clean the controller's exterior with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Check Connections: Ensure all wiring connections are secure and free from corrosion. Loose connections can lead to intermittent operation or system failures.
- Monitor Event Log: The controller records up to 50 events circularly. Regularly review the event log for any recurring issues or unusual activities, which can aid in proactive troubleshooting.
- Firmware Updates: Check with the manufacturer for any available firmware updates to ensure optimal performance and access to new features.
6. Troubleshooting
This section provides guidance on common issues you might encounter with your HAT560N/HAT560NB ATS controller.
6.1 Diagnostic Features
The controller can display its current status, including the state of digital input/output ports and detected abnormal conditions. Utilize this feature to diagnose problems.
6.2 Common Issues and Solutions
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on | No DC power supply; loose power connections. | Check DC power input (B-, B+). Ensure connections are secure. |
| ATS not transferring automatically | Incorrect system type setting; abnormal voltage/frequency detected; controller in Manual mode. | Verify system type configuration. Check voltage/frequency readings. Ensure controller is in Automatic mode. Review event log for fault codes. |
| Over/Under Voltage/Frequency alarm | Actual power source voltage/frequency outside set limits; sensor issue. | Check the power source quality. Verify controller settings for voltage/frequency thresholds. Inspect AC voltage input wiring. |
| Loss of Phase / Reverse Phase Sequence alarm | Incorrect phase wiring; phase loss in power source. | Verify 3-phase wiring sequence (A1, B1, C1, N1 / A2, B2, C2, N2). Check power source for phase integrity. |
| Remote communication failure | Incorrect LINK wiring; ModBus configuration error; network issue. | Check LINK terminal connections. Verify ModBus parameters and network connectivity. |
