Anyone know if it matters how you place the optical level sensor in the water? Sideways? Facing up or facing down? Does it matter? All of a sudden having an issue with the one on my ATK so checking before I ask Neptune. thx

Facing up or sideways only. Facing down can allow a bead of water to stick to the tip and give false CLOSED readings.

Thanks. Something isn’t right. Acts like its stuck open.. Whether its in water or not it stays open. if I unplug it then it shows closed when in the water but then changes to open after few minutes. I went ahead and sent in a support request. appreciate it
Sounds like you have it configured for auto-detect or leak and not configured for optical. Go back into module setup and make sure it's set right.

its configured properly. had that issue a month ago when I bought it and IAMCHADSTER pointed out the config page. I have it set to sensor.
Does the module firmware show (OK)? That could also cause the behavior you describe if it shows (OLD)

yes it shows ok. When the power went out yesterday afterwards it showed an X or !, cant recall but after i rebooted it everything worked. i didn't pay attention to the OLS at that point it was today that i noticed it wasn't working but again the module reports good. i even re-uploaded the update just to make sure. It reports OK. Seems to be the module bc the sensors are pretty simply. cant really see an issue with the sensor itself.
Thanks. Currently its working. Guess I'll just have to keep an eye on it for now
Since this is already open I figured I would just ask in here instead of a new thread. Does anyone know the pinout of these sensors?
You won't get any help with anything like that here. Not publicly, anyway.
Can anyone tell me the sensor position on the sensor mount?
Are the sensor position 1 on the top and sensor 2 on the bottom? Or vice versa?
I am confused of it after switching over the way the sensors facing.
My programming is as follows:
Fallback OFF
Set OFF
If Swx4_1 OPEN Then ON
If Swx4_2 CLOSED Then OFF
When On > 005:00 Then OFF
Defer 000:10 Then ON
Defer 000:04 Then OFF
Min Time 060:00 Then OFF
and my sensor is showing as follows:

Currently, the bottom sensor is at water level and is in the closed position, and the top sensor is way above water level and in the open position.
It seems like the sensors are switched. I don't dare to add the pump to it and cause a major tank problem.

Looks like you have it correct. For optical sensors, CLOSED is wet, OPEN is not in water.
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 think I got it. Based on my progrmming above, if SWX4-2 IS now open, and if water keeps pumping in and reaches it, it will then be CLOSED, then the PMUP will shut off. Is this correct?

If I add a third optical sensor in SWX4-3, and place this in the sump, while sensors 1 and 2 are in the main tank, how would my program below looks like to have it shut off the PMUP when water reaches the 3rd sensor? is the following correct?
Fallback OFF
Set OFF
If Swx4_1 OPEN Then ON
If Swx4_2 CLOSED Then OFF
If Swx4_3 CLOSED Then OFF
When On > 005:00 Then OFF
Defer 000:10 Then ON
Defer 000:04 Then OFF
Min Time 060:00 Then OFF

I’ve had issues with my sensor in the ATO water storage attracting bubbles and giving me false readings. Blows up my phone and email and drives me crazy. Have to wipe off the bubbles off the sensor every couple days.
Horizontally. It’s my low water sensor in the storage box.
My tank is a 35g Read Sea Max with a build in sump with skimmer on the back of the tank. I have since added an overflow box, and a DIY 2 to 3 gallons sump below in the tank's cabinet.
Currently, I use a Hydor Probe Sensor ATO with the probe in the sump area. It had an accident caused by the overflow not "overflowing" to the sump, making the ATO continuously adding water diluting and overflowing the main tank.
Putting the sensor on top make more sense. But, it seems like it can cause the same problem too at the sump if the sensors are placed on top.
I think I might be able to place the Apex ATK sensors on the sump area after taking off the float valve. But, it can also cause the sump overflow problem just as before when the ATK fails to stop pumping to the main tank above.
I have ordered an additional Apex sensor, intending to have the 2 main sensors (without float sensor/valve) placed in the sump while the 3rd sensor placed in the main tank build in sump area (given if the main senors without float valve fits in my mini sump).
Can you tell me if this will avoid my overflowing main tank / sump problem with the following programming? Any help is greatly appreciated.
Fallback OFF
Set OFF
If Swx4_1 OPEN Then ON
If Swx4_2 CLOSED Then OFF
If Swx4_3 CLOSED Then OFF
When On > 005:00 Then OFF
Defer 000:10 Then ON
Defer 000:04 Then OFF
Min Time 060:00 Then OFF

I personally would do it the other way around. Have the ATK unit in the sump to control that level with the extra sensor in the main tank protecting against overflows. The code you showed will work for that.
