    programming my ATO

    Hi,
    i would like to have help programming my ATO .
    actually i have this program in this outlet


    Fallback OFF
    Set OFF
    If ATOADD CLOSED Then ON

    If ATOVID CLOSED Then OFF
    Defer 000:20 Then ON
    Min Time 010:00 Then OFF


    which correspond to ON when swith (a float) is closed
    defer tell to wait 20 second for the float to be steady on before start the pump
    min time tell to wait at least 10:00 between each start
    set it to off when ATOVID swith (not enough fresh water) is CLOSED


    i would like to be able to put something who will tell the outlet to run no more than 15 seconds when it start.


    that's because it happen randomly since couple of weeks that the float "ATOADD" do not recover the "OPEN" status immediately when water reach his level . So the outlet can run 1:00 to sometime 3:00 who is making a big change in my parameter when this happen.


    I haven't found information about how to set a max time to run. I found OSC but i think that i do not really understand the function of OSC because i haven't been able to realize what i really want.


    hope you'll be able to help me.


    thanks.

    What do you want to happen when the max time is reached? Do you want it to self reset and try again a certain amount of time later or do you want it to lock out, alert you, and stay off until you reset it?

    You might be an engineer if...You have no life and can prove it mathematically.

    I want it to turn off like if the float sended the signal of "enough water".
    Just to prevent me the problem that the float do not send the signal. Normally, 10-15 seconds of water is enough.

    You cant just turn it off, because the float is still closed so it will get stuck in a loop.

    You can either have it latch off and manually reset or force it OFF for a set amount of time before it tries again.

    If I understand correctly, the solution I use is a virtual outlet that creates a periodic 'window':

    ATO_ALLOW
    OSC 000:00/000:35/010:00 Then ON

    ATO
    Fallback OFF
    Set OFF
    If ATOADD CLOSED Then ON
    If ATOVID CLOSED Then OFF
    If Output ATO_ALLOW = OFF Then OFF
    Defer 000:20 Then ON

    The ATO_ALLOW VO creates a 35 second window during which the ATO could run. This is the desired 15 seconds of run time plus a 20 second delay caused by the DEFER in the ATO outlet. Then the 'window' closes for 10 minutes, before it repeats.
