Help with L5104D5: 4 Channel Dimmer

Hi Guys,

Have had one of these units installed in the house for 2 years now with no issues. It seems that one of the channels (3) may have jammed itself on.

The buttons on the front do not register the channel 3 on.
Pushing 3 has no effect
Powering on/off the unit has no effect.

Toolkit shows 0.9 amps being drawn on channel 3 (correct as the lights are stuck on).

Any ideas ? Is the channel just dead (stuck on).

Finally I suppose my only option is to buy another (eek) as in the UK.

Pro series dimmer locked on

Check to make sure your not using any "or" logic channels

 

Sorry, whats an 'or' logic channel ?

Can you set logic up in such a way to break the front of the unit led on/off displays ?and in such a way that a toolkit 'off' is completey ignored. And in such a way that you break cbus messaging/state- i.e that cbus thinks the channle is off and reports it as off ?

Sounds like a damaged triac.I`ve had this problem with quite a few pro dimmers.Have there been any faults on that circuit?I`ve had lamps blowing which caused the triac to blow!

 

Hey,

Possibly yes - the lamps do blow occasionally on my circuits. Never had a problem up till now though.

Guess its a nasty to fix ?

yeah.. i'm agree with this...
