Configuración e instalación
Que hai na caixa:
- 1 x DIN rail mount indicator light module
Montaxe do módulo:
The module is designed for easy installation on standard DIN rails (35mm, 32mm, or 15mm). The carrier can also be detached for panel mounting applications.
- Montaxe en carril DIN: Align the module's clips with the DIN rail. Press down firmly until the module snaps securely onto the rail. Ensure it is seated properly and does not wobble.
- Montaxe no panel: The DIN rail carrier can be disassembled from the main PCB. Once detached, the PCB can be mounted directly to a panel using appropriate standoffs or screws (not included).

Instrucións de cableado:
The module features 5.0mm pitch screw terminal blocks for connecting input signals. Each LED channel (1-16) has a dedicated input terminal, and there is a common (COM) terminal.
- Prepare fíos: Strip approximately 7mm (0.28 inches) of insulation from the ends of your wires (26 to 12AWG / 2.5mm²).
- Connect Inputs: Loosen the screws on the desired terminal blocks. Insert the stripped wire ends fully into the terminal openings. Tighten the screws to secure the wires. Gently tug on the wires to ensure a firm connection.
- Common Connection: Connect the common return path of your control circuit to the "COM" terminal.

Modos de funcionamento
The OONO D-1003T Series supports both Common Positive and Common Negative control configurations. This flexibility allows integration into various existing control systems.
Common Positive Control:
In this mode, the "COM" terminal is connected to the positive supply voltage. Each individual channel terminal (1-16) is then connected to the negative side of the control signal. When a channel's input is pulled low (connected to ground or negative supply), the corresponding LED will illuminate.
- Connect the positive supply (e.g., +5VDC to +50VDC) to the COM terminal.
- Connect the negative side of your control signal for each channel (1-16) to its respective input terminal.
- LED illuminates when the input terminal is connected to the negative potential.
Common Negative Control:
In this mode, the "COM" terminal is connected to the negative supply voltage (ground). Each individual channel terminal (1-16) is then connected to the positive side of the control signal. When a channel's input is pulled high (connected to positive supply), the corresponding LED will illuminate.
- Connect the negative supply (e.g., Ground) to the COM terminal.
- Connect the positive side of your control signal for each channel (1-16) to its respective input terminal.
- LED illuminates when the input terminal is connected to the positive potential.

Mantemento
The OONO DIN Rail Mount 16 LEDs Indicator Light Module is designed for long-term, maintenance-free operation. However, periodic checks can help ensure optimal performance.
- Limpeza: If necessary, gently wipe the module with a dry, soft cloth to remove dust. Do not use liquid cleaners or solvents.
- Comprobación de conexión: Periodically inspect terminal block screw connections to ensure they remain tight and secure. Loose connections can lead to intermittent operation or damage.
- Condicións ambientais: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent premature component degradation.
Resolución de problemas
| Problema | Causa posible | Solución |
|---|---|---|
| No LEDs illuminate. | No power supply to the common terminal, incorrect common connection, or no input signal. | Verifique o voltage is within 5-50VDC. Check common terminal wiring (COM). Ensure input signals are correctly applied to individual channels. |
| Specific LED(s) do not illuminate. | Faulty input signal to that channel, incorrect wiring for that channel, or damaged LED. | Check the input signal for the specific channel. Verify wiring for that channel is secure and correct. If all else fails, the LED may be damaged and require module replacement. |
| LEDs are dim or flicker. | oferta insuficiente voltage, loose connections, or excessive current draw from other components on the same supply. | Asegurar a subministración voltage is stable and within range. Check all terminal connections for tightness. Isolate the module to confirm power supply stability. |
| Module does not mount securely on DIN rail. | Incorrect DIN rail size or improper mounting technique. | Ensure you are using a 35mm, 32mm, or 15mm DIN rail. Press firmly until the clips engage. |
