    ATK Gets Confused by Hight Water

    When I go into feed mode my return pump turns off and the sump fills up higher then the High Water Sensor, I get an alarm which i muted and or defered in the EmailAlm_15 Code. But it seems that the ATK gets confused due to the longer period of high water. Can i just put a defer statement in the last line of code which will keep the ATK Happy and return to normal operation after the feed time. For instance:

    Fallback OFF
    Set OFF
    If ATKLow OPEN Then ON
    If ATHigh CLOSED Then OFF
    When On > 005:00 Then OFF
    Defer 000:10 Then ON
    Defer 000:04 Then OFF
    Min Time 060:00 Then OFF
    If FeedA 015 Then Off
    If FeedB 015 Then Off

    Thanks

    What do you mean by "ATK gets confused"?

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

    I can'tBe sure what the poster means, but in my situation I have the ATO defer 30 minutes after the return pump comes back on. Even though no top off as needed , The pump starts and add to top off water even though the sensors should be telling the ato not to. This only happens after power has reapplied and does not happen at other times.

    My system is doing the same thing after a power reset. It runs the pump for the (When On > 004:00 Then OFF) setting then turns off.....Even though the sensors should tell it not to run.

    Fallback OFF
    Set OFF
    If Swx11_1 OPEN Then ON
    If Swx11_2 CLOSED Then OFF
    When On > 004:00 Then OFF
    Defer 000:10 Then ON
    Defer 000:04 Then OFF
    Min Time 060:00 Then OFF

    Make sure your FMM module firmware is updated and the sensors are set to optical (dont use auto-detect it's buggy).

    When in auto-detect the FMM can sometimes get confused and mistake an optical for a leak sensor or vice versa, which reverses CLOSED and OPEN states if that happens. The chance of this occurring is somewhat low, but can have very detrimental effects if it does happen. Better to be safe and just tell the FMM what is in each port so it can't ever get confused.

    Funny thing - just had a power blip and my alarms went bonkers related to the high ATK sensor. I'm not sure if the pmup turned on as I have about 115 pages of output logs from the high ATK sensor flapping like an animal. I even have a defer statement in the high sensor. SumpH is the high ATK sensor, the below is the virtual outlet code for the sensor (i tend to use a lot of VO's so I can use longer names)

    SumpATOHigh:
    Set OFF
    If SumpH CLOSED Then ON
    If Output SkimmerPump = OFF Then OFF
    Defer 000:20 Then ON
    Defer 000:10 Then OFF <--- just added this to see if it helps, haven't tested yet.
    If FeedA 000 Then OFF

    Got a ton of emails too - all of them were simply the blank ON/OFF notifications, none told me what actually went on and off. Indicative of a flap

    (I know this thread is slight diverging, just adding color) I also noticed that while my Apex stayed online as as 2 of my 3 powerbars are on UPS, but one of my powerbars lost power just for a moment, so some of my non-UPS backed stuff went offline for a moment, triggering fallback I imagine.
