FGS-223 (with euFix S223) : Multiple unmanaged lamps on the same circuit Sx (safe ?)

[fubar 0]

Hello,

 

I installed a FGS-223 instead of a standard impulse switch.

 

In the electrical panel, in addition to the main line and neutral wires, I only have access to a single wire (line) which goes to multiple lamps switches (some are momentary switches, some simple switches) and the 2x switches return wires and 2x lamp wires from my 2x existing standard momentary switch (impulse switch).

Everything belongs to the same breaker

(in my country, line goes to the switches).

 

I put schematics of a dimmer since it matches whats written on the eufix adapter more accurately.

 

In drawing 1, everything is working correctly, but I'm wondering if my wiring is "safe" ? I used Sx instead of L for the switches wire.

 

In drawing 2, that's something I'm considering, but I don't know if it's safe as well.

 

One last question :Do you know if Sx is still powered (by L) in the event the FGS-223 breaks down ?

Attention!

you are in the "Double Switch 2" section, you are talking about FGS-223, which is correct. But you are using the diagram from the Dimmer module!

Moreover, it contradicts the manufacturer's instructions (and is not valid for any module variant).

Specify the module type, update the diagram.

Are you saying that Eufix has a poorly written description/visual, or did you just buy a different adapter than the module you have?

I have the eufix S223 for the FGS-223 :

Ok, so you have the right module, the right adapter and you are in the right section of the forum. That's it. So why are you using a Dimmer in the schematic?

Because it matches more closely whats written on the euFix, I have no idea why it's different...

[Martin_N 154]

I disagree with your statement. The Dimmer module has a regulated output and allows for two-wire connection. The FGS-223 has a switched output and two-wire mode (without N connected to the module) is not possible!

It is confusing for all readers of your post. Please redo the diagram according to reality.

 

I think I understand what you mean.

1 light controlled by Fibaro module

1 light controlled manually by a regular switch

1 light/s controlled via pulse relay

Please redo the diagram and I can help.

The diagram is exactly the same, with Q1 instead of the arrow symbol. I don't know how the FGS is "wired" behind the euFix adapter and I'm not at home so I can't open it to check the circuit tracks. I'm wondering where the Sx of the euFix goes to, maybe it's just bridged to L with a fuse in-between ?

Actually, there is more than 1 light controlled by a regular switch, but yeah that's the idea.

-> 1 light/s controlled via pulse relay : I haven't connected this one yet, for now the module is working with regular switches but I wanted some advice before going on.

Oh, I didn't notice that Eufix has the S223 model with the power input terminal marked as Sx.

Now it's clear to me. Below I've attached a few pictures with an explanation.

C)

Switching via an impulse relay, outside the FGS-223 circuits.

Here we are only talking about small currents, usually up to 250mA for switching the relay coil.

If connected via Eufix S223, this should not be a problem, but I recommend connecting it the same as in case B), i.e. directly to phase L.

 

 

Note:
On the PCB it can be seen that phase L is connected directly without any inserted circuit or fuse. The main problem is in the narrowed path. This is not a design error, it is only a matter of distributing the control signal voltage for the inputs.
This must be kept in mind and adapted to (respectively, respect the manufacturer's recommended connection).

Merry Christmas.

Thanks, but my problem is I only have one wire that goes to all the switches from the electrical panel. So I have to choose : either I plug it on Sx, or on the L from my main and not use Sx at all.

According to your warnings, I should unplug Sx and connect it on my breaker's L output, right ? Moreover since you have found out Sx is just bridged to L without any fuse, it seems pretty useless...

 

Merry Xmas too

Yes, you are right. The Sx terminal is only there for the Eufix adapter to simplify the installation. In your case, you can (and because of the B connection, you have to) connect the switches directly to L.

 

And as a result, you will actually honor the recommended connection of the manufacturer Fibaro for the FGS-223

Have a nice day/good n.
