What this guide covers
This guide is for electricians who need a quick way to determine whether an RBC412 wireless receiving controller is dimming correctly. The video demonstrates the simple test and the response to look for.
Before you start
- Only carry out electrical testing if you are competent and authorised to do so.
- Confirm that the connected lamps or driver are dimmable and compatible with the controller.
- Have the RBC412 data sheet to hand so the test can be checked against the correct wiring and load requirements.
Step-by-step instructions
- Check that the controller has a stable supply and that the lighting load operates.
- Carry out the dimming test exactly as demonstrated in the video.
- Observe whether the load changes smoothly through the expected dimming range.
- Use the result to separate a controller issue from a pairing, wiring or load-compatibility issue.
Useful tips
- Test with a known compatible dimmable load wherever practical.
- Record the controller and load details before contacting support; it makes diagnosis much quicker.
- If switching works but dimming does not, check load compatibility and installation details before replacing the controller.
Troubleshooting
If the RBC412 does not respond correctly, safely verify the supply, wiring, connected load and paired switch against the product data sheet. Do not work on live equipment unless the test procedure specifically requires it and you are qualified to do so.
