    DOS won't turn on with schedule

    Hi, please can someone help me. I've programmed my Dos, as below, but the Dos doesn't appear to activate the profile at the allotted time!

    Program for DŌS Pump 1 on the DŌS named DOS_3 at Aquabus address 3.

    Fallback OFF
    Set OFF
    If Time 20:00 to 20:01 Then DosMix
    If Time 20:01 to 20:02 Then DosFeed
    If Time 20:02 to 20:03 Then DosFlush
    If FeedD 003 Then DosFlush
    If FeedD 001 Then DosFeed
    If FeedD 000 Then DosMix

    Here are the three profiles

    ID 30
    Name DosMix
    Type Dose
    Dose Rate 125 mL / min
    Pump Direction Reverse
    Per Dose Amount 15 mL
    Dose Intervals 30 seconds
    Dose Count 1

    ID 31
    Name DosFlush
    Type Dose
    Dose Rate 125 mL / min
    Pump Direction Reverse
    Per Dose Amount 60 mL
    Dose Intervals 100 seconds
    Dose Count1

    ID 32
    Name DosFeed
    Type Dose
    Dose Rate 250 mL / min
    Pump Direction Forward
    Per Dose Amount 15 mL
    Dose Intervals 200 seconds
    Dose Count 1


    It's driving me crazy as to why it's not turning on! If I just use SET ON then it starts, I'm really confused!!

    Cheers,

    Ali

    Obvious question but just checking.... Have you double checked your time to make sure it is correct in Apex? Does the Dos run when you activate feed cycle?

    Hi, thanks for the reply. I can confirm the time is correct and it doesn’t turn on when in feed mode :-(

    I don't have the DOS, but looking at the manual there is a TEST profile.

    https://www.neptunesystems.com/downl...DOS_manual.pdf

    Have you tried a test using it? If I understand correctly, the minimum Dose Count is 2?

    There is no test profile. The example given in the DŌS manual is just an example, and says that you can modify a profile to be used for testing. The minimum Dose Count is one; 2 is merely the example used in that same section of the DŌS manual.
    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.

    I meant to suggest creating the test profile illustrated in the manual to determine if it would run and eliminate any possible error with the users existing profiles. Thanks on clearing up the Dose Count, I was confused by the caveat (dose + interval) in the definition.

    Hi guys, the Dos is functional (I’ve calibrated) and if I write the statement Set ON it will turn on. My question is more of a programming question as to why it won’t activate the profile at the allotted time. Cheers

    The only thing that I see is some overlap in the time/feed commands. Normally, this wouldn't be an issue since the last true statement should prevail. But, I don't know if this affects how profiles would work. I wouldn't expect it to be an issue, but maybe it is. Start simple and work your way up.

    Try it without a profile:

    Set OFF
    If Time 20:00 to 20:01 Then ON
    If FeedD 000 Then ON

    If that works, try it with just one profile:

    Set OFF
    If Time 20:00 to 20:01 Then DosMix
    If FeedD 000 Then DosMix

    And so on.

    I'm curious as I'm new to DOSing, but what is the above programming doing?

    Which? In my last post, I showed two different simplified approaches in an attempt to isolate the problem. The first was without a profile. It would activate the device for the allotted time interval or if the Feed was initiated. The second was identical except it used a single profile.
