Package Contents:
- PIKO G Scale Switch Decoder 35013
- Instruction Manual (this document)
- Mounting Screws (if included)
Wiring Instructions:
- Power Connection: Connect the decoder to your digital command station or a dedicated accessory power supply. Refer to your digital system's manual for specific power requirements and connection points. The decoder typically requires a stable DC or AC voltage, usually 16-24V.
- Track Connection (if applicable): Some decoders can draw power directly from the track. If your decoder supports this, connect the appropriate terminals to your track power bus.
- Switch Motor Connection: Connect the output terminals of the decoder to your G scale turnout motor. Most turnout motors have two or three wires for control (e.g., common, straight, diverging). Ensure correct polarity as per your turnout motor's specifications.
- Mounting: Secure the decoder in a dry, protected location under your layout using the provided mounting screws or suitable adhesive. Ensure it is easily accessible for future adjustments or troubleshooting.
Note: Always double-check all connections before applying power to prevent damage to the decoder or other components.
Operating Instructions
Once installed and powered, the PIKO 35013 Switch Decoder can be configured and operated using your digital command station.
Addressing the Decoder:
Each switch decoder needs a unique address to be controlled independently. Consult your digital command station's manual for instructions on how to assign accessory addresses. The PIKO 35013 typically supports DCC (Digital Command Control) protocols.
- Programming Mode: Place your command station into accessory programming mode.
- Assign Address: Follow the prompts on your command station to assign a desired accessory address to the decoder. This usually involves sending a specific command or pressing a button on the decoder itself (if available).
- Test: After assigning the address, exit programming mode and test the turnout operation by sending commands from your command station to the assigned address.
Controlling Turnouts:
To change the position of a turnout connected to the decoder:
- Select the assigned accessory address on your digital command station.
- Send the "throw" or "close" command (often represented by 'T' or 'C', or a specific button) to change the turnout's position. The turnout motor will activate, and the points will move.
- Observe the turnout to ensure it moves to the desired position.
Maintenance
The PIKO G Scale Switch Decoder 35013 is designed for durability and requires minimal maintenance. However, following these guidelines can help ensure its longevity:
- Environment: Keep the decoder in a dry, dust-free environment. Avoid exposure to extreme temperatures or humidity, which can damage electronic components.
- Cleaning: If necessary, gently wipe the exterior of the decoder with a soft, dry cloth. Do not use liquid cleaners or solvents.
- Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation or damage.
- Physical Damage: Avoid dropping or subjecting the decoder to physical shocks, as this can damage internal circuitry.
