Setup and Installation
Follow these steps to properly set up your automatic signal:
- Track Integration: The signal main body is integrated with a 64mm straight track. For longer track sections, combine it with the two included 30mm auxiliary straight tracks to achieve a total length equivalent to a 124mm straight track. This allows for flexible placement in various layout configurations, including tight spaces or near points.
- Power Connection:
- Connect the signal to a DC 12V power source.
- Compatible power sources include:
- KATO 22-018/018BK Power Pack Standard SX (with 22-082 N AC Adapter)
- KATO 24-829/829BK Accessory Adapter
- KATO 22-081 Power Connector connected to a 22-082 Power Pack Hyper DX
- Important: Do not use power packs older than the KATO 22-012 Power Pack Standard S, as this may cause product malfunction.
- Ensure a secure connection using the provided cable. An accessory adapter (e.g., 24-829) is often required to connect the signal to your power pack.
- Layout Integration: The signal is designed for N-Gauge Uni-Track systems. Its compact design allows for improved freedom of installation.

Operation
The KATO 20-606 Automatic Signal operates based on vehicle detection:
- Automatic Signal Change: The signal utilizes a flange touch sensor for reliable operation. When a vehicle passes over the sensor, the signal light sequence will automatically change from Green → Red → Yellow → Green.
- Reverse Direction: If a vehicle reverses direction over the signal, the signal will consistently display Red.
- Stop Signal Button (Sold Separately): The signal is compatible with the KATO 24-848 Stop Signal Button. Pressing this button will force the signal to always display Red, overriding automatic operation.
- Analog/DCC Layout Identification: The signal automatically identifies the power supply method of your layout (Analog or DCC).
- DCC Layout Specifics: In a DCC layout, the signal will turn Green when standing, regardless of the direction of progress. To reverse the signal direction in a DCC layout, you must use the KATO 24-848 Stop Signal Button to force it to Red.
Maintenance
The KATO 20-606 N-Gauge 3-Light Automatic Signal is designed for durability and reliable performance. Regular maintenance is generally not required beyond keeping the track and sensor area clean from dust and debris to ensure proper vehicle detection.
- Ensure track connections are secure and free from corrosion.
- Gently clean the sensor area on the track with a soft, dry cloth if operation becomes inconsistent.
Troubleshooting
- Signal Not Functioning:
- Verify that the signal is correctly connected to a compatible DC 12V power source.
- Ensure you are not using a power pack older than KATO 22-012 Power Pack Standard S, as this can cause malfunction.
- Check all cable connections for security. An accessory adapter (e.g., KATO 24-829) is often necessary for power connection.
- Inconsistent Signal Changes:
- Ensure the track and the flange touch sensor area are clean and free from obstructions.
- Verify that vehicles are passing over the sensor correctly.
- Signal Always Red in DCC Layout:
- In DCC mode, the signal turns green when standing. If you require it to be red, use the KATO 24-848 Stop Signal Button (sold separately).
