    DOS Code Help-short duration, defined speed and volume

    I'm looking to use my DOS to drive a kalk reactor, specifically the TLF KW 300 because it's been laying in my basement for a few years. It has a spinning nozzle at the end that needs decent volume to spin and stir the kalk properly. This setup is serving two purposes. One is that my CARX was driving my pH down, and the other is that my CARX solenoid died. Using kalk will allow me to save up for a bit and get a better regulator setup.


    I'd like to start by dosing 100ml at a rate of 250ml/minute every three hours. I'd like to keep the code simple to modify as my demand changes. I tried setting my DOS to follow the following profile, but it didn't work as I expected. Note that 10,800 seconds adds up to 3 hours. Also note that my battery has decent charge left.


    What do I need to change here? Note that I have it set to turn off in case of high pH or ATO emergency floats and my system evaporates in excess of 2000ml/day so I have plenty of room to adjust the dose.Thanks for the help!

    The interval actually doesn't matter for this part. Pick any random number that it will accept and keep number of doses at 1.

    Create a virtual outlet with the code

    OSC 000:00/005:00/175:00 Then ON


    In the DOS use

    If Outlet Virtualoutletname = ON Then profilename

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

    Thank you

    I waited a little bit to comment so I could see how it works. Well, it appears to be working perfectly.

    It ran the dose at 0000, 03, 06, 09, 12, 15, 18, and 2100. What is strange is that it also dosed at 1000 and 2200. I changed the OSC to 000:00/001:00/179:00 and will see how it goes.

    The on time needs to be at least 1 min 12 seconds in the event the pump takes rest breaks during the dose. I would use 2 minutes if you want to reduce on time.

    DOS Code Help-short duration, defined speed and volume

    So, I've gotten Triton additives and would like to check the code here. My intent is to have 10 equal doses from each DOS, and each part starting 10 minutes after the preceding part. This should allow me to easily adjust the dosing volume in increments of 1ml/day and keep the parts seperated by the 5 minutes recommended by Triton.

    Note that the OSC commands are modified in each outlet, but I'm only verifying the concept and safeties.

    If Output TritTim_1 = ON Then PF7-Core7
    If ATOE OPEN Then OFF
    If pH > 8.50 Then OFF
    If pH < 7.50 Then OFF
    If DTemp > 86.0 Then OFF
    If DTemp < 65.0 Then OFF
    If Time 22:00 to 11:59 Then OFF

    Thanks again for the help

    Using a DOS in a similar fashion but to feed a Nitrate Reactor.
    I use the wizard to pump 36,000ml in 24hrs on one head.
    The system sets it up at 125ml/min, 143doses, interval 10min with about 250ml per dose.
    How do you get the screen posted above that allows setting of the pump speed?
    Mine is running faster than necessary and very noisy.
    Would rather have it run slower and somewhat continuously.

    You cant slow it more than it already is. The minimum speed allowed with the DOS is a 1/3 duty cycle, which for your daily amount is a minimum speed of 75ml/min. You would need to reduce the daily dose to below 28,000 to let it drop down to the lower speed of 60ml/min.

    Thanks a lot!
    Reduced to 28,000 and it’s now at 60ml/min.
    Will see what effect the change will have on levels.
