Ensure Q1 is off when Q2 is on and v.v.

Question

Hello,

I have a  AC- fan with 2 Levels. 

Please login or register to see this link.

 There is a toggle-switch for Off - Level1 -Level2. The lower speed is managed by using an elko. 

To control it with HC3 I use an Double switch FGS223. Works fine, but I don't know what happens when Q1 an Q2 are switched on at the same time.

So I like to ensure that this can't happend.

 

Any idea how i can mange this?

 

Thanks for helping me.

Gerhard

 

I used as well an dimmer but this gives me, as expected, a terrible noise.

I expect  you can manage this only by a scène with double switch 2. 
 

with the double smart module you can enable a parameter that doesn’t allow both outputs to be turned on. So that is an alternative option.

    That is what I'm doing. But even when I hide the devices they are still there. 😁 

    The 3 scences work perfect. To have a scene on my dashboard I have to create an QuickApp? (Never doing this)

    That's new to me. I will look for the specific parameter. 

     

    Thanks for your input!!

    Can't find the parameter. But you said "smart module". I use double switch FGS 223. I think that is the reason.

    BTW the GUI is awful. When I open parameter all parameters sticks on the left side. It is hard to read.

    @ggoetz56 Hello.

    The solution will be quite simple, but space-consuming.

    You will need one relay with a changeover contact. Connect Q2 to one coil terminal, the other coil terminal to N.

    Connect Q1 to the COM contact of the relay. Connect the NO contact of the relay to the I. engine speed. Connect the NC relay contact. and II. engine speed.

    It will then work in such a way that you will control the motor speed through Q2 (switches I. and II.). You will switch the fan on/off via output Q1.

    This solution assumes that the motor speed is switched directly to phase L. The fan does not contain any rear electronics for speed switching. Most of these fans are made in such a way that you actually connect phase L to a different winding of the motor.

  • Thank you Martin,

     

    I read it 5 times but I think I have to make a drawing. 😚

    A changeover relay like this one?

    Not.

    This is a relay that has two sets of NO contacts. Terminals COM + NO (normal open).

    You need a relay that has a switch contact. So the COM (middle) switches between NO (normal open) and NC (normal close).

    Please login or register to see this spoiler.

     

    Note: the motor is connect to N, I. and II. must setting via the phase L.

    If it is other diagram, please write and attach the photo.

    @ggoetz56

    As I wrote that other wiring diagrams can be used, I meant the case where neutral N is switched by a switch on the motor, for example, or some other voltage needs to be switched, from some electronics.

    Then, of course, it will be involved a little differently.

    Yes! L is connected to the switch. Position 2 provides 220v and Position 1 provides 150 V.
