    Default Dosing with 30 minutes difference?

    I am using timer 28 to dose Magnisium: 24 dosings per day / 5ml per dose / every day (flow rate 41ml/minute).
    I am using timer 32 to dose kH: 24 dosings per day / 13 ml per dose / every day (flow rate 43ml/minute).

    I need theese products to be added with 30 minutes from each other.

    How can I do that?




    **My other dosing pumps acts like this:
    Timer 25: Manu.dosing 4ml at 15:00
    Timer 26: Auto dosing 1 dosing per day / 1ml per dose / every day (flow rate 55ml/minute)
    Timer 27: Auto dosing 24 dosings per day / 3ml per dose / every day (flow rate 42ml/minute)
    Timer 28: See above
    Timer 29: Manu.dosing 15ml at 12:00
    Timer 30: Manu.dosing 8ml at 21:00
    Timer 31: Manu.dosing 6ml at 14:30
    Timer 32: See above

    Possible would be (not tested)

    • increase of timer 28 to 48 dosings (all 1/2 h)
    • increase of timer 32 to 48 dosings (all 1/2 h)
    • new timer with programm "cyclic", "min. wait time" of 1800s and also a "max. wait time" of 1800s
    • new programmable logic1, function AND with input1 timer 28, not inverted, not delayed and input2 the new timer, not inverted, not delayed
    • new programmable logic2, function AND with input1 timer 32, not inverted, not delayed and input2 the new timer, inverted, not delayed
    • assign new programmable logic1 to Magnisium socket/dosing pump
    • assign new programmable logic2 to kH socket/dosing pump


    The function is as follows: The dosing units try to dose all half hour, but only one of the two can dose due the cyclic timer allows only one to be active.
