    I have a 4-20ma sensor that measures a TANK level 4ma - Empty 9.3ma is Full

    I am trying to get my head around the Channel Operation mode. I want 4 group addresses to come ON and OFF at different levels.

    I was going to do in PAC but I thought I could do here as well. If I am wrong please let me know.

    I assume I need event mode but not single load or Bank Switch ?

    Why does Single Load turn on Bankswitch ?? when selected ?


    One of the other annoying things is that you cannot see the current "Current" level in the circuit (great for commissioning)

    Could I add to the WISH list to get the Current flowing in the "Show Current Level" since you need to set Channel Op Mode in Milli Amps and not the unit that you are Scaling to..

    Any help would be greatly appreciated.

    Probably not the answer you want to here, but my last experience of programming a General input module failed using toolkit, I tried various versions and could not get it work as expected.
    I was lucky enough to have learnt about these beast in C-Bus V2 software and always thought that the layout in that software was better. So I dug out an old PC with XP on and put V2 on it with a serial PCI and successfully programmed the unit, I then had a looked at the programming in toolkit and saved the info again, which wrecked the results, on opening via V2 software parameter's had changed, Today I won't modify that unit using toolkit, it works great measuring voltages for me.

    Thanks for the tip. Mine seems to program OK. It did work in the end. I have the other 3 channels monitoring pump current so I can tell if running too long and if the rota gets locked by debris
