    DOS Missing Dose

    I'm using a DOS for AWC and every so often it misses a dose for no reason.

    Profile Configuration:

    Name: WtrChange
    Type: Dose
    Rate: 250ml /min
    Pump Direction: Forward
    Per Dose Amount: 375ml
    Dose Intervals: 600 seconds
    Dose Count: 5

    NSWDos

    Fallback OFF
    Set OFF
    If Time 20:00 to 21:30 Then WtrChange
    If Time 10:00 to 11:30 Then WtrChange
    If Output vNSWLo = ON Then OFF
    If Output vHi = ON Then OFF
    If Output vBsmtLeak = ON Then OFF
    If Output vTankLeak = ON Then OFF

    OSWDos

    Fallback OFF
    Set OFF
    If Time 20:00 to 21:30 Then WtrChange
    If Time 10:00 to 11:30 Then WtrChange
    If Output vNSWLo = ON Then OFF
    If Output vHi = ON Then OFF
    If Output vTankLeak = ON Then OFF
    If Output vBsmtLeak = ON Then OFF

    It appeared in this instance to have missed the NSWDos at 10:11:33 for some reason. From the code, the only thing that could have stopped the AWC was either running out of NSW (NSWLo), my sump being too high (vHi), or a leak. The thing is that if any of them were triggered, it should have stopped both NSWDos & OSWDos and not just one or the other.

    Add a defer then OFF (like 10 seconds would be fine) to both. I would also suggest using the wizard for your scheduled change rather than profiles.

    Can you explain what you mean by a defer statement?

    The person that helped me set up my DOS recommended that I do it using profiles. Is there a reason to change it since, for the most part, it's working? I'm always skeptical that I'll screw something up when I make major changes.

    The wizard is much simpler and is almost idiot proof. You select a time interval and a total volume for the interval and the apex figures put the rest.

    You would then click the gear icon to get to the advanced tab and copy over your if output statements and add this line as well

    Defer 000:10 Then OFF


    This forces it to wait until any of those statements is true for 10 seconds before shutting off.

    Do I delete the Profile (WtrChange) and both virtual outlets (OSWDos & NSWDos) and then use the wizard?

    The OSWdos and NSWdos outputs are not virtual outputs- they are the real ones which directly correspond to the two pumps. You can’t delete them.

    You also cannot delete profiles. You can simply rename ones you no longer use back to their default name or something like that.
    Please do not send me PMs with technical questions or requesting assistance - use the forums for Apex help. PM me ONLY if the matter is of a private or personal nature. Thanks.
