Common C-Bus faults

Lighting flicker ghosting & LED Issues

One of the most common issues in older CBUS systems occurs after replacing traditional halogen lamps with low-power LED bulbs.

  • Lights flickering intermittently
  • Single bulbs staying ON when switched OFF
  • Dimmer instability
  • Ghosting - some lights stay on when the circuit is off
Cause:
Older C-Bus dimmers were originally designed for higher electrical circuit loads of 200W+. Modern LEDs often draw less than 5W, causing unstable dimmer operation.
Recommended Solution:
Install load correction devices at each dimmer channel to stabilise the circuit and restore reliable operation. Or replace the dimmer with one of the new SpaceLogic options.

C-BUS Network lock-ups

Intermittent C-Bus communication faults can become more common as installations age.

  • Switches flickering randomly
  • Lights failing to turn ON or OFF
  • Entire CBUS network freezing
  • Faults appearing inconsistently
Possible Causes:
Deterioration of electronic components, mechanical faults, unstable bus power supplies, or damage caused by power surges and lightning events.
Diagnosis:
These faults can be extremely difficult to locate, especially when the issue is intermittent and not present during testing. Once the problem is found it usually a case of replacing the part thats causing the intermittent fault.
