Relay Problems

[richskiddle 0]

I've got some fibaro re;ays 2 x 1.5kw

However I am still having an issue with one of the relays. It was working as expected on both channels, now one channel, the main lights is permanently on and nothing will control it, not even the switch.

ANy ideas?

richskiddle, sometimes, when non-resistive load is connected to the relay, the connectors can weld together. What was connected to this switch? To temporary repair Relay, just tap it a few times e.g. with screwdriver, and it should go back to normal. However such situation can repeat if inappropriate load was involved. Of course you can also start warranty procedure.

...such situation can repeat if inappropriate load was involved....

Fibaro please spell it out, what type of loads are inappropriate for FGS 221 and FGS211?

Just experienced this problem on two of my FGS 211. One controlling a small valve motor, the other a number of fluorescent lamp tubes - total of 180W.

The time since installation for both about a year and a half. This is not good enough for me.

I have no intention of running around my smarthouse manually tapping all my FGS boxes.. Some of them not so easy to get to anyway. I need devices fit for purpose, so please advice.

1152, as i mentioned in another topic, the Relay you used for motor was being toggled too often. And about lamp: it is capacitive load. 2x1,5kW should not be used for loads other than resistive, while 3kW should work fine in most installation. However in some grids they can fail too, so the safest solution if you need to operate loads other than resistive is to use external relay.

And worth mentioning is that this is not something that is unique to Fibaro and their modules but is the same for all manufacturers. It's well knows stuff if you know a little about electricity, electronics and electronic components.

Thank you for a quick response. My posts are specifically about the FGS-211/3kW. The Technical Data section of the FIB_FGS-211 documentation clearly states: “Attachable Loads 16 A (3500 kW), lower at very inductive or resistive loads“. I believe it should read capacitive loads and not resistive loads.

Yes, I know. How the customers are informed varies though:

That said: I don’t think Fibaro or others will find the public supportive for an approach with the need for an extra relay…

Have a Look at this:

It is German i Hope you can understand it. I can say that this thing works fine without any problems.

You can rebuild this ESB 1 you need one fuse and one ntc. I have build some of this things and it cost about 3~4€..

P.S. My english is not the best

The other problem not mentioned so far with the relays is that you will not get a warning or any other indication (except "the physical evidence" eg the change that should have occured based on the the issued zwave command does not happpen), The HC2 will happily report that the switch changed from on to off and vice versa , but in reality it does not happen... So depending on the situation it may take some time before you know you have a problem (or a cascading problem)
