Multiple control for skimmer help

[Cali9dub]

Here is my goal: (1) to have my skimmer turn off when skimmate is full via the use of a level sensor (2) have my skimmer off for maintenance/water change (3) have a delayed start after the maintenance function is disabled or power outages ,etc.
I have my skimmer on maintenance 3 that is 120 minutes of various equipment off for maintenance (works as intended)
I have a level sensor that when skimmate is full it shuts down the skimmer and triggers an alarm (works as intended)
How do I add a 2 minute delay after a power outage or after the maintenance function has ended or been disabled ??

the skimmate full function is using control circuit 1 (leakage detection, fill), level sensor 1

I’m shakey at best with advanced programming so I need some help with this one to make it work correctly or clean up what I already have.

I assume it needs to be done in programmable logic of which I don’t find to be very logical. Lol

Can you post your function for your skimmer´s switch channel

Answers are in the Knowledge Base. :)

Once the functions are setup, use PL to combine functions. In this case, you'd be combining the leak function (skimmer off when cup is full) with the maintenance delay, then assign it to the socket that powers the skimmer. The AND function would be used here.

Here is the switch, what maint it is also attached to and the level sensor info:

I would combine your current function with a maintenance mode delay as described in Vinny´s answer. It could look like this

Create a PL like this gate x (in my example gate 31) -

Create a new PL (in my example gate 32)

Knit this last PL to the actual socket - in my case S63. NOTE the blackout delay - to set this to 2 minutes - you delay the socket for 2 minutes after a power blackout or after a break of connection between the PB and the computer

I have not test this - please test it before you run it sharp

Didn’t work. Skimmer just stays off

 

[Lasse]

Does the first (your original settings) works - just to knit the socket with the level function ?

I´m sorry did not test. Have done that now. You need to do gate 31 (in my example) in the second PL (gate 32 in my example) inverted - as this

I’ll give it a go when I get home from work. Thanks so much !

That worked !! Thanks. I still don’t understand The invert ??

 

[Lasse]

The first version state (in order to have the socket active) that both argument should be true (no full skimmer cup and maintenance 3 active (with delay off)) When you invert the argument maintenance 3 delay off - you simply state the opposite. The socket is only active if skimmer chamber is not full and if maintenance 3 delay off is not active.
