Fix 5000CT [Discontinued Legacy Unit] Stuck-On Channels | Clipsal C-Bus Repairs Sutherland Shire

⚠️ Discontinued Unit — No Manufacturer Support

The C-Bus 5000CT MKII series (including SC5000CTL2 and C-5000CTDL2) is a discontinued legacy wall-mount control panel for Clipsal C-Bus systems. Clipsal no longer provides firmware updates or manufacturer support for these units. Independent specialist repair is the only option.

Direct Answer: C-Bus 5000CT MKII Touch Screen (Legacy) — Stuck-On Channels

Stuck-on channels are typically caused by fused load contactors inside the relay. When inrush currents exceed the relay rating, the contacts weld together, keeping the lights permanently on.

Step-by-Step Diagnostic Steps

Attempt to manually toggle the channel override button on the unit.
If the button is physically stuck or does not change the light state, the relay is fused.
Turn off the circuit breaker for the affected lights to save energy.
The internal relays cannot be safely un-welded.
A hardware replacement of the dimmer or relay module is required.
