Solenoid timing for RODI Storage

[XLOR8T]

I’m brand new to this Apex programming this and don’t want to screw this one up.

So my RODI Brute can hold 40 Galons (has float valve hooked up to RODI system)

I have put a Solenoid on that line and a optical sensor in the 20% mark in the barrel.

I don’t want to constantly store 40 gallons so I wanted to write a code so when the low sensor triggers the solenoid opens for 1 hour (which makes about 10G of new RODI) so please bare with my Terrible code and help me:

Fallback OFF
Set OFF
If RODI_L OPEN Then ON
When On > 060:00 Then OFF
Defer 000:10 Then ON
Defer 000:04 Then OFF
Min Time 060:00 Then OFF

That won't work. If you want to run an hour at a time whoever it goes low you need this

Fallback OFF
Set OFF
If RODI_L OPEN Then ON
When On > 120:00 Then OFF
Defer 000:10 Then ON
Defer 000:04 Then OFF
Min Time 060:00 Then ON



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

So the water fell below RODI_L triggered open but the water is well above the sensor and it’s still showing open. I shook it a bit (didn’t want to have to remove it if I don’t have to. Checked that it is active on FMM, Re updated software on FMM. Still showing open and it’s underwater. I’ve been waiting for over an hour. Any ideas? Do I have to remove the sensor to get it above water and see what’s wrong? Is this common? Kinda scary if they are used as failsafes.

Thank you

Is it fully submerged or just part way? If it is fully submerged, the when statement acts as a failsafe and will shut off after 2 hours.

Check the connector. A lot of people don't press them all the way in to the click.

Ya was fully submerged. And the sensor wasn’t reading closed. I don’t believe that has anything to do with programming.

I checked that it was fully plugged in and still no response. Eventually I unplugged and Replugged it to get it to work. I’m going to keep an eye on it next time it drops below. I set an alarm for it to notify when it’s open. And I’ll see if it works right.

Thank you

I’m trying to understand what each line of this code actually means. Can you please help with a 1 liner after each so I know what the code makes the system do.

Thanks a lot!!

Fallback OFF
Set OFF
If RODI_L OPEN Then ON
When On > 120:00 Then OFF
(Sets to manual OFF if switch is still open after 2 hours)
Defer 000:10 Then ON
(Filter)
Defer 000:04 Then OFF
(Filter)
Min Time 060:00 Then ON
(Runs for at least 1 hour any time it turns on)

So the program ran again today and the sensor didn’t go back to closed. It ran over the 1hr which I assume is because the sensor still showed open and it ran till it hit the 2 hour safety and it went to OFF not auto. (Again I believe that’s because it’s supposed to be failsafe) I’ve opened a ticket with Neptune support. I have to unplug and Replug that sensor for it see closed.

Interested in what response you received from support... I too use an optical sensor on my RODI tank to trigger the re-fill.

My FMM module has an occasional issue with the optical sensors as well. I found that 're-booting' the FMM module (unplugging all connection to it) has given me a 'reliable' period of running until it doesn't...

Hi. After a few days of testing and eliminating the other variables, we have determined that the sensor is faulty. They are processing a replacement. Support experience has been fantastic, and I’ve learned a lot about my apex in the process )
