    Why did pump run past time specified?

    I have dosing pumps set up for Triton dosing. I want each pump to run for just over a minute each hour for 8 hours (between 0900-1700). Although the OSC part worked perfectly, the pumps dosed every single hour all night long. What am I doing wrong?

    Fallback OFF
    If Time 09:00 to 16:59 Then ON
    OSC 001:06/058:54/000:00 Then OFF


    Thank you for the assistance!

    OSC has explicit on and off states so the If Time statement is overridden / ignored. An OSC must be the first regular program statement (except for a Fallback statement). Your program logic is wrong, and you are using the more difficult variant of OSC.

    Use this:

    Fallback OFF
    OSC 0:00/1:06/58:54 Then ON
    If Time 17:00 to 08:59 Then OFF
    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.

    Thanks for the assistance! I'll make the changes and test.
