    ATK - Pump Shutoff, Low RO Reservoir

    I assumed that the ATK pump was capable of turning off automatically if the reservoir was low/out of RO water. Can it?

    Currently, I set a max on time and a deferral period to try to prevent the pump from burning out. I have woken up twice with the pump running none stop, not sure for how long it was running.

    Fallback OFF
    Set OFF
    If Swx5_1 OPEN Then ON
    If Swx5_2 CLOSED Then OFF
    When On > 002:00 Then OFF
    Defer 015:00 Then ON

    I am assuming the pump has no capability of knowing the water level. If I want it to shut off, I would need to buy digital eye to detect the low water level in the RO reservoir and then program the pump to shut off it water levels in the reservoir is too low.

    The When statement will automatically shut the pump off 2 minutes after the reservoir level is too low. The pump will run dry for those 2 minutes unless you also install a float or additional optical switch.

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

    Your best bet is to add a sensor into the resovoir
    im using the optical sensor with the magnetic mount place about three inches from the bottom of the tanks
    works well although I have only let my water get below it once and then in testing

    Yep without a sensor in your container it will still run if the ATK calls for the pump to add water. The when > 2 min will turn it off as a safety feature but it will still run dry for about 2 minutes.

    Heres how I added one to my setup.

    I would like to add a 3rd optical sensor in my reservoir to the ATK FMM (low water level)

    what is the process to add the 3rd sensor and what code to add.

    I want the low level optical sensor in my reservoir to stop the top off ATK pump from running. and send an alarm.

    Add this line to the end of the ATK code

    If switchname OPEN Then OFF

    Same line into email alarm but use ON instead of OFF

    There is a Task in Fusion to do this: ATK - Low Water
    Please do not send me PMs with technical questions or requesting assistance - use the forums for Apex help. PM me ONLY if the matter is of a private or personal nature. Thanks.

    But if you make it that easy, it takes all the fun out of it

    And I will not learn unless I ask and try to do it myself. like to know how the system works. But yes I do see the task for adding this. Thanks to you both.

    waiting on a support call today to debug a leak detector problem I am having. Hope to learn from that also.
