Dimmer 2 overcurrent problem

[treboR 3]

Hello,

 

I'm having a strange problem with multiple dimmer 2 modules.

 

When ever I connect a laptop charger ( of vacuum cleaner ) the modules will shut off and report overcurrent. After 5 seconds the light turns on again.

 

one of them has one Osram 30 - 105w transformer connected with 2 35w halogen spots behind it. So the load isn't the issue. The electric system is brand new ( new home ) and the modules are connected with 3 wires.

 

I've tried using a dimmer 2 bypass to maybe filter the "overcurrent" but that also does not work. This is pretty annoying since I have 40 of these in the house now. Would be a shame if this is normal..

 

Thanks in advance,

 

Robert

I got the same problem too and got the response from Fibaro that they want me to send in the dimmers and they will update the firmware.

 

My problems are similar:

- Connecting eg a drill/saw to the same fuse gets my Halogen light to shut down and then return to the same state of 1-2s.

- Connecting a Fibaro dimmer 2 and Switch to the same "Line" but for 2 different lights. During operation of the Switch it causes the dimmer to shut down the light for the dimmer for 1-2s.

Ha ha ha treboR,

 

Luckily I have some spare ones on the shelf.

I think, as stated in the reply of KristianO, it's a firmware issue. My Dimmer 2's were the first one sold in The Netherlands

so the primary model. I don't know which version is now being sold. What version do you guy's have?

[treboR 3]

I have firmware versions 3.2 and 3.3 ( all 40 dimmers are version 2 ). But as far as I know I have the issue with both firmware's. Will check this when home from work.

[KristianO 15]

According to Fibaro the new firmware with a solution is not release yet. That's why they asked me to send them in to "fix" the problem.

My concern is that I do not want to tear down my house for weeks to solve this. Im hoping the new firmware will be release soon or Fibaro makes it possible to do a remote firmware update.

[TRicky 84]

I use version 3.2 and with the Dimmer 1 I never had these problems. 

So in most areas where this problems occurred I changed a Dimmer 2 with a Dimmer 1.

Problem solved but not the best solution.

[KristianO 15]

Same here! I had this issue in 5 places, The initial dimmer "solved" my problem. But im not happy.

[treboR 3]

The power consumption feature is one of those things I wanted. But I'm pretty sure Fibaro will come up with a solution. But will wait on your results TRicky

 

Also forgot to mention, did you experience any flickering with these dimmers? I have..

[TRicky 84]

Nope treboR,

 

But most dimmers are well loaded and the ones with small loads have a Bypass 2.

There's no flickering in my house (when I'm sober, lol)

[Guest chaicka]

I do not have such luck. Dimmer 1 resulted in the LED dinning light flickering after switch on for awhile or when tuning up or down brightness. Dimmer 2 fixed all these but introduce a new problem - switch off for 1-2 seconds at the moment when other lights in the same circuit are switched on.

Haha nice. But in my case I have dimmers with 200watt of load and some around 70watt ( all halogen icm Osram Haltronic transformers ) and they all flicker from time to time. Do you have the by pass 2 fitted at the halogen load aswell?

No, all my halogen loads are higher then 50W. All small loads are led spots.

I have 18 dimmers 2. Serval ones with bypass 2. There are a lot of problems with the dimmer 2. Flickering, Switching of when Switching on dimmer next to each other. 2-way switch not working. It is time that Fibaro is coming op with some solutions! The dimmer 2 is not working in the way they sell it!

[TRicky 84]

Today I finally had the time to exchange the Dimmer 2's for other one's.

Strange enough that one exchange solved the problem but the other exchange didn't make any difference.

They will be posted tomorrow to Fibaro and let's see what they will find out....

[treboR 3]

Thats sort of good news! Do you see any difference in the revision/firmware version?

[Sankotronic 2,370]

I use for now only two dimmer 2 modules. One for living room main light with four Osram dimmable LED bulbs each around 9W, other is for parking space controlling seven Osram dimmable LED bulbs each 10W and now all working as expected.

 

When I installed dimmer 2 for parking space there were seven Osram LED bulbs each 7W non dimmable and it didn't work correctly. These LEDs were causing surge on dimmer so turning ON these LEDs was erratic, sometimes turned on but most of the time not with surge fault. Then, after I replace these common LED bulbs with new dimmable I still had problems but because one of the new LED bulbs was with manufacturing problem and died next day. Finally when this bulb was replaced no more problems occurred except that occasional flickering. This I eliminated with turning off automatic calibration, and I also play with parameter 2 "max. brightness level" to reach maximum brightness and not causing module to have any of the faults. Actually there is this part in operating manual that says:

 

"There is a 10% probability that calibration settings will require a

manual correction. In a 2-wire connection for loads other than resistive

parameter 1 settings must be adjusted manually."

 

In my case is a 2-wire connection and manual calibration really was needed to make it working properly.

 

Regarding this problem with vacuum cleaner or drill influencing dimmer I can test and come back with results since I have also lighting and sockets on same circuit and fuse. I am not happy with that but previous owner of the house make it that way to save some money

Still all good? Can you see any difference in the rev. of firmware version?

[TRicky 84]

Still the same situation.

And all modules (original & replaced) are Version V 3.2

 

And no report from Fibaro till now

The problem that is discussed here, occurs in versions up to and including version 3.3 under certain conditions. Unfortunately, I cannot tell you when the next firmware version will be available to the public. I assume when you are talking about "replaced", you mean this was done by your dealer. Or maybe Fibaro didn't have the next version ready at that time? Anyway, may I suggest you to hold on until the next HC firmware release? If you can't wait, I think your only option at the moment, is to talk to support...

[TRicky 84]

No, I replaced them with Dimmers that I still had on the shelve. Last July I bought 14 pieces of and din't install them all till now.

So the replacement was from the same first shipment (first one's in the Netherlands)

Perhaps a new firmware will do but most of all, first wait on the report of Tech support when they have investigated my 2 modules.....

[petergebruers 1,268]

Ah! Thank you for explaining that. So they've got your modules. Good!
