Key Features:
- 16 track occupancy detection sections.
- Occupancy detection via current monitoring.
- R-Bus connection for integration with Z21 systems.
- Configuration via push button or POM-CV programming.
4. Setup
Follow these steps to set up your Roco Z21 Detector X16:
- Power Disconnection: Before beginning installation, ensure that all power to your model railway system, especially the track power, is completely disconnected.
- Mounting: Choose a suitable location for the detector, preferably close to the track sections it will monitor. Ensure it is protected from dust and moisture.
- Track Section Wiring:
- Identify the 16 track sections you wish to monitor. Each section requires isolation from adjacent sections and the main track power.
- Connect one rail of each isolated track section to the corresponding input terminal (1-16) on the Z21 Detector X16. The other rail of each section should remain connected to the main track power bus.
- Ensure secure and correct polarity connections for reliable detection.
- R-Bus Connection: Connect the R-Bus port on the Z21 Detector X16 to your Z21 central control unit using a standard R-Bus cable.
- Power Connection: Connect the power input of the Z21 Detector X16 to a suitable power supply as specified in the Z21 system documentation.
- Initial Power-Up: Reconnect power to your model railway system. Observe the Status and Error indicator lights on the detector. The Status light should indicate normal operation (refer to Operating Instructions for light behavior).
5. Operating Instructions
The Z21 Detector X16 operates by monitoring current draw in the connected track sections. When a locomotive or rolling stock with current-drawing components (e.g., lighting, decoders) enters a monitored section, the detector registers occupancy.
Indicator Lights:
- Status: Indicates the operational status of the detector. Typically solid green for normal operation.
- Error: Illuminates or flashes to indicate a fault or wiring issue. Refer to the Troubleshooting section.
- Program: Used during configuration via push button or POM-CV programming.
Configuration:
The detector can be configured using a push button on the device or through POM-CV programming via your Z21 central unit. Consult your Z21 central unit's manual for detailed instructions on POM-CV programming for R-Bus devices.
- Push Button Configuration: Specific functions can be assigned to the push button for quick setup adjustments. Refer to the detailed Roco Z21 X16 manual for specific button press sequences and their functions.
- POM-CV Programming: This method allows for advanced configuration of the detector's behavior, such as sensitivity adjustments or addressing, directly from your Z21 control software or app.
6. Maintenance
The Roco Z21 Detector X16 is designed for reliable, long-term operation with minimal maintenance. Follow these guidelines:
- Cleaning: Keep the device free from dust and debris. Use a soft, dry cloth for cleaning. 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 detection or errors.
- Environment: Ensure the detector is operated within its specified environmental conditions (temperature, humidity) to prevent damage.
