ATO Pump not shutting off with APEX

[genericfishname]

I recently picked up a used Apex classic. I added a break-out box, (diy) and two float switches in ports one and two. I am struggling to get the ATO function to work properly. Any advice is welcome. I verified the pin out of the break out box with a VOM and a diagram of the connector found on an older thread. The pumpis on outlet 3. It turns on but then keeps going after the high level switch should kick it off.

Fallback OFF
Set OFF
If Sw1 OPEN Then ON
If Sw2 CLOSED Then OFF
Defer 001:00 Then ON

oddly, i also have this error every hour

First and foremost, what kind of ATO pump is it? Second, are these optical switches or actual floats? Are you running the Neptune ATK kit?

It is a cheap Amazon pump I had previously used with my reef-pi. I have it restricted down to do less than a gal/min. I am using basic float switches mounted one a 1/4" higher than the other in a custom 3d printed holder. I am not using the ATK kit.

This is my programming. Maybe some of this will be of assistance.

Fallback OFF
Set OFF
If FeedD 000 Then OFF
If ATK_RO < 2.0 Then OFF
If LEAK CLOSED Then OFF
If ATK_LO OPEN Then ON
If ATK_HI CLOSED Then OFF
When On > 010:00 Then OFF
Defer 000:10 Then ON
Defer 000:04 Then OFF
Min Time 030:00 Then OFF

I believe you may have an alarm configured for that port which is why you're getting the alert every hour.

If you're using an EB8 I would use outlet 4 or 8.

@genericfishname

You should be able to take @blaxsun ATK's programming and just change it to something like:

Fallback OFF
Set OFF
If FeedD 000 Then OFF
If Sw1 OPEN Then ON
If Sw2 CLOSED Then OFF
When On > 010:00 Then OFF
Defer 000:10 Then ON
Defer 000:04 Then OFF
Min Time 030:00 Then OFF

You can change the FeedD to a feed mode you're actually using or eliminate it completely if you're not using feed modes, or add a line for all of the feed modes if you use them all.

This also breaks down the commands, so you know what they are doing instead of blindly copying code. It's for the ATK but is well written and adaptable to your ATO - https://forum.neptunesystems.com/showthread.php?26967-ATK-Troubleshooting-Tips

Thank you all very much! I will continue testing this tonight and report back.
