PMUP with Os-1 optical sensor

[HardDog]

I am going to put a skimmate accumulation tank in service. This tank will collect excess skimmate. When somewhat full I want the sensor activate the PMUP to run approximately 0:15. Any help in programming this set up?

I wouldn't recommend using an optical sensor with skimmate. It's too likely to gunk up and misread, so a float switch is more reliable.

With that said, you want something like this

Fallback OFF
Set OFF
If Switch CLOSED Then ON
Min Time 000:15 Then ON
When On > 002:00 Then OFF

Email
(Existing code)
If Error Outletname Then ON

This will run 15 seconds when the switch closes and if for some reason the switch is still reading closed after 2 minutes it will go to manual OFF and send you a text.

thank you for that information. Which float switch would you recommend? I have the ones that would require the instalation of a breakout box and I have one that has a male plug in that is a little to large for the FMM so, I have a reducer on it and it would plug in.

Floats have to go into a breakout box.

The best and most reliable I have used are madison floats (just dont forget to buy a nylon nut cause they dont include one for no good reason).

What if the skimmer is going crazy? Do you want to shut it down?

That can be done with additional failsafes, but requires some initial testing first on how often "normal" is to be effective.

If for example the pump typically ran once every 3 hours then you could add a failsafe like this (assumes switch opens at high level). This would detect if the pump ran in the last 90 minutes before the switch closed again and if it did, it shuts off the skimmer for 6 hours as a precaution.

SkimTimer
Set OFF
If SkimSwitch OPEN Then ON
Defer 090:00 Then OFF

StopSkimmer
Set OFF
If SkimSwitch OPEN Then ON
If Output SkimTimer = OFF Then OFF
Defer 002:00 Then ON
Min Time 360:00 Then ON

Skimmer
(Existing code)
If Output StopSkimmer = ON Then OFF
