Skimmer Control (12 hrs pause) by Programmable Logic
Hello,
Could anyone please help me to set up a programmable logic function for my skimmer?
What I’m intending is as follows.
When I feed coral food and hit feed pause 1 (FP1) at around 23:00, the skimmer stops until I hit feed pause 2 (FP2) next morning,
or a timer gives a reset signal around 11:00. (for about 10~12hours).
This is for preventing the skimmer from overflow or the coral food is stripped by the skimmer too early.
I tried to write a programmable logic as follows.
G1 : Or (PL1)
Input 1 : FP2
Input 2 : Timer 1
G2 : SR-flipflop (PL2)
Input 1 (set) : FP1
Input 2 (reset) PL1
Timer 1 (Process)
Event start at 11:00
Power Outlet 5
PL2
Invert
This programmable logic does not work, so I tried to add a pulse (1s) after FP1 and FP2 before the input of their next gate, but nothing changed.
I tried with Maintenance Mode, but the duration is too short, 5 hours?
I fully understand the functions of those logic gates by my background, but I’m a very beginner for the PL of P4.
What did I do wrong?
Could you please give me a tip to achieve the function?
Thanks in advance.
Son
