    Cor 20 ramp up / startup e graph. programming

    14 years in the hobby and finally started buying Neptune products, started out with the other stuff that is no longer being produced.

    I bought a COR 20 pump to replace a different failed pump about 4 months ago.

    I was running it stand alone external and had issues received parts and no fix, finally got it figured out. The soft start is too strong/fast, but I can get it to go if I start it low and ramp up manually to my desired speed.

    Now I have upgraded the controller to the an Apex and have the same startup problem, Fusion has helped and says it is in a run dry fault. But if I graph it at a low start point It goes.

    I see there is a way to program this to occur automatically at startup but where do I get information about the coding? Key words? Scripts? Etc?

    Can someone point me to a resource, or provide an example to try?
    Ive seen a few things that seem close.

    What I’m looking for is:
    Powerup / start up / maintenance?
    start at 5% then ramp up to the desired level on the graph
    over about 1 minute.

    Thanks

    Instead of using the graph, use profiles and the advanced coding window.

    First, set up the IQ so that 100% becomes your desired flowrate and 1% becomes your feeding flowrate (if you turn it off completely, just keep that a 1%).

    Make a ramp profile with a minimum of 1% and a max of 100% with a duration of 1 minute.

    In the COR code use this format

    Fallback ON
    Set profilename
    If FeedA 000 Then 1
    (Other feeds, shutoff for low water level etc.)

    Zombie's post has a slight error... the Start Intensity value in the profile should be 5%.
    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.

    I made the assumption he would set IQ minimum to 5% if that's what he wants his feed intensity to be. Not an error, just perhaps not explained in enough detail.

    Thank you both, where or how do I create this ramp profile? I know where the IQ Intensity is, and where to do the advanced profile opposite the graph.

    Folder icon is where the profiles can be edited/defined.

    So how’s this

    Fallback On
    Set 100
    If feedA 100 Then On
    If power Apex Off 001 then Startup (named Ramp profile)

    If you dont intend to change the intensity during feed, leave that line out completely.

    Change set 100 to set profilename.

    The power line is unnecessary since the ramp will start over upon reboot anyway with just the set statement.
