5. Instal·lació i configuració
Before beginning installation, ensure all power to the automation system is disconnected. The R93/RX20/U receiver is designed for integration into existing control panels or enclosures.
5.1 Muntatge
- Choose a suitable location within the control panel or a separate protective enclosure. The location should be dry, protected from direct sunlight, and away from large metal objects that could interfere with radio signals.
- Secure the receiver using appropriate screws or mounting hardware (not included) through the designated mounting holes on the enclosure.
- Ensure adequate ventilation if installing in a confined space.
5.2 Cablejat
Connect the receiver to the control unit according to the following guidelines. Refer to your automation system's control panel manual for specific connection points.
- Font d'alimentació: Connect the 12/24 V AC/DC power supply to the designated power input terminals on the receiver. Observe polarity if using DC power.
- Sortides de relé: The receiver has two relay outputs. Connect these outputs to the corresponding input terminals on your automation system's control board. These outputs typically trigger actions like opening/closing a gate or activating a light.
- Antena: Connect the 433.92 MHz antenna (if external) to the receiver's antenna terminal. Position the antenna for optimal signal reception, away from metal obstructions.
Nota: Incorrect wiring can damage the receiver or the connected automation system. If unsure, consult a professional electrician or installer.
6. Instruccions de funcionament
Once installed and powered, the receiver is ready to receive signals from programmed 433.92 MHz fixed code transmitters. When a valid signal is received, the corresponding relay output will activate, triggering the connected function in your automation system.
6.1 Programming Transmitters (Remote Controls)
The R93/RX20/U receiver can store up to 50 unique fixed codes. The programming procedure typically involves a button on the receiver itself. Consult the specific instructions provided with your ROGER TECHNOLOGY transmitter for detailed pairing steps, as these can vary slightly.
- Locate the programming button (often labeled "PROG" or "LEARN") on the receiver module.
- Press and hold the programming button for approximately 2-3 seconds until an indicator LED (if present) illuminates or changes state. This indicates the receiver is in learning mode.
- While the receiver is in learning mode, press the desired button on your 433.92 MHz fixed code transmitter.
- The receiver's LED should flash or change state again to confirm successful programming.
- Repeat for any additional transmitters or buttons you wish to program, up to the maximum of 50 codes.
- To exit learning mode, wait for the receiver to automatically time out (usually after 10-15 seconds) or press the programming button briefly again.
6.2 Erasing Programmed Codes
To erase all programmed codes from the receiver's memory:
- Press and hold the programming button for approximately 8-10 seconds.
- The indicator LED will typically flash rapidly or remain solid for a moment, then turn off, indicating all codes have been erased.
- Test the previously programmed transmitters to confirm they no longer activate the receiver.
7. Manteniment
The ROGER R93/RX20/U receiver is designed for reliable, low-maintenance operation. However, periodic checks can help ensure its longevity and performance.
- Neteja: Keep the receiver's enclosure clean and free from dust and debris. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Connexions: Reviseu periòdicament totes les connexions del cablejat per assegurar-vos que estiguin ben fixades i que no presentin corrosió.
- Medi ambient: Assegureu-vos que l'entorn de funcionament es mantingui dins dels rangs de temperatura i humitat especificats.
- Antena: Verify the antenna is securely connected and positioned optimally for reception.
