    Question 1 time DOS

    I'm wondering how I can setup to do a 1 time DOS?
    For example I DOS 2 part using 1 set of DOS pumps

    I have another DOS pump that I would like to be able to DOS Magnesium as needed. When I do a water test and I determine I need 500ml of Magnesium as an example. I would like to DOS that over maybe 10 hours and then STOP. I do not want it to DOS again ever till I go in and tell it to.

    How and I do that?

    Create a virtual outlet with this code

    VOname
    Set ON
    When On > 720:00 Then OFF

    Define a DOS profile that spreads the dose how you like. In the DOS use this code

    Set OFF
    If Output VOname = ON Then profilename



    When you want to add mag, set the VO to AUTO. It will automatically shut to manual off after 12 hours.

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

    Thank you for your quick response...

    I created the virtual outlet:
    VO12hrDOS
    Set ON
    When On > 720:00 Then OFF

    Now I'm trying to create a profile as you stated above. I selected the profile type as DOS. I'm stuck on finding information about how the options work:

    DOS/Rate 7ml/min ;I understand this one
    Pump Direction forward ; I understand this one
    Per DOS amount ; don't understand
    DOS intervals ;don't understand
    DOS count ;don't understand

    Lets say I want to DOS 500ml total, what values would I use.

    I googled DOS profile setup etc, but I was not able to find anything.

    Thanks,
    John

    These are not DOS interval, DOS count, etc. They are "per dose amount", "dose count", etc.

    It's covered in the DŌS manual found at https://www.neptunesystems.com/support/docs/

    Thank you very much... I've read that before and here it is

    Profile Name – Any unique name you chose, 8 characters or less, no special characters
    Control Type – Select ‘Dose’Dose Rate – Select the appropriate rate for your application. Note you can select 7, 12, 25, 60, 125 or 250mL/min in either forward (in to out) or reverse (out to in) direction.
    Per Dose Amount (mL) – enter the dose in mL that you want.
    Dose Interval (s) – What is the interval between the end of this dose and the end of the next dose?
    Number of Doses – How many doses (dose + interval) per run of this profile?

    Hence my question, which I do not understand...

    Same ? above, how do I fill out the form for example to DOS 500ml????

    is it Per Dos Amount multiplied by the Number of Doses

    do I for example put 100 in dos amount then 5 doses to equal 500ml????

    Correct. Interval is how far apart. Total dose is individual dose times the DOS count. Just make sure the interval is such that all the doses occur in less than 12 hours.

    Per Dose Amount (mL) – 5
    Dose Interval (s) – 300 seconds
    Number of Doses – 100

    Is my understanding and math correct then...

    5ml DOS times 100 DOSES = 500ml
    at a rate of every 300 seconds it would be 8.3 hours to dose 500ml

    10 DOS times 50 DOSES = 500
    at a rate of every 60 seconds it would be 8.3 hours to dose 500ml
    That would only take 50 minutes. Set interval to 800s and it will take about 11 hours. You could also do 1 mil per dose for 500 doses at an interval of 1 minute and it will does that in 500 minutes or 8.33 hours.
