    Apex FMM and optical sensor programing

    I have 3 new optical sensors connected to an FMM. They are dry now and I believe show closed in fusion. See picture. I thought they should show open???

    Screen shot 2018-06-16 at 3.26.59 PM.png

    #2 is in my skimmer slime jug and needs to shut off my skimmer if it gets too full and I forget to look. What would the programing look like?

    If SWX7_2 OPEN Then 3_8 OFF (this is the skimmer pump at DB8)

    If SWX7_2 OPEN Then 4_1 OFF (this is the skimmer air pump at DB8)

    Questions:
    Will the device number work (3_8) and (4_1) or do I need to use the name I made up?
    Do I need any statement to have them turn back on or will they do that when the level drops below the sensor?

    Also the other 2 sensors are in my ato and mixing containers. I can use them to shut off the 24v power to the RO/DI solenoid when they get full? Should this be done at the DB8 outlet number for the power supply?

    If SWX7_1 OPEN Then 4_7 OFF (4_7 is the power brick for the FMM power)

    If SWX7_4 OPEN Then 4_7 OFF (4_7 is the power brick for the FMM power)

    Or should I have the FMM do it. If i go the FMM route what would the programing look like?

    Thanks in advance

    Note:
    My RO/DI comes on for a short period of time each day to replenish to ATO container and put some water in my mixing barrel. The process is not sensor driven. These are back ups in case something goes a miss.

    They should not show closed unless they are covered in water. Did you plug them in all the way?

    I unplugged them and plugged them back in and now they read open. Will my statements work if change the "open" to "closed"?

    I have my Rodi System plumbed into the sump with 2 Shut off solenoids(ATOSolenoid1,ATOSolenoid2) and a float valve in the sump. I recently installed the FMM with one optical sensor (SUMPLV) to monitor the sump level. I would like to set a program for both Solenoids after five minute of the optical sensor being open to trigger both solenoids to open for five minutes or a different time duration then close and repeat the process until the optical sensor reads closed. Any help would be much appreciated!

    Use OSC to get the desired pattern you want when open and then add a shutoff line for the optical being closed. I would also suggest using stuck open detection to shut it off or use a slower OSC in the event the optical fails open.

    That wont do what you originally asked for (unless you changed your mind on how you wanted to approach it)

    To do more like what you originally asked for you would want something like this.

    Solenoid
    OSC 000:00/005:00/015:00 Then ON
    If SumpLV CLOSED Then OFF
    If cond < 34.0 Then OFF
    If Output ATOstuck = ON Then OFF
    Defer 000:10 Then ON
    Defer 000:10 Then OFF

    ATOstuck
    Set OFF
    If SumpLV OPEN Then ON
    Defer 120:00 Then ON
