    Kalk stir program

    I have my kalk reactor fed by a peristaltic pump that turns on every hour on the hour. I want to program my kalk stirring pump to automatically turn on for 1 minute whenever the dosing pump turns off so it will mix everything up for the next dose on the next hour. I thought I could do this with the following line but it doesn’t work.

    If outlet kalk = off 001 then on

    Any help is appreciated.

    The only way to do exactly what you asked for is this

    StirStop (VO)
    Set OFF
    If Output Kalk = OFF Then ON
    Defer 001:00 Then ON

    Stirrer
    Set OFF
    If Output Kalk = OFF Then ON
    If Output StirStop = ON Then OFF

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

    This works. Thank you. This makes it much easier for me to adjust my kalk dosing and keep the longest possible settling time before the next dose.
