    ATO/Kalk Stirrer Code Sanity Check

    Hey Guys-

    Been having problems with my ATO/Kalk Stirrer on my frag tank. About a week ago, my Apex went offline due to a short power outage and when it came back on, one of my FMMs was not registering, hence the FRAGTO optical switch wasn't present and the ATO ran for a few hours spilling all over the place and driving my SG down to 1.018.

    In an attempt to avoid this happening again, I added a When On > statement to keep it from running too long.

    Problem is, now I am finding my levels too low and my ATO shut off all the time. I have filled it up and set it back to Auto in hopes of avoiding the shutoff due to run time. I am also noticing that my ATO (BRS dosing pump) will continue running even after the FRAGTO switch is registering as Closed, and we aren't talking 10 seconds... I have the pump on outlet 8 of one of my EB8s and it shuts off fine when I switch it to off or the 12 minutes goes by. Can't see any issue with the FRAGTO optical switch either. Very strange.

    Below is my code, maybe I have a statement priority causing this??

    Fallback OFF
    Set OFF
    If FRAGTO OPEN Then ON
    If FRAGTO CLOSED Then OFF
    Defer 002:00 Then ON
    If pHx6 > 8.65 Then OFF
    When On > 012:00 Then OFF

    Thanks in advance!

    Is the pump plugged into an electromechanical outlet (4 or 8 on and EB8 or any outlet on an EB832)
