Hi everyone.
I am looking at moving a psi control loop that is currently ran by a single loop psi controller into a slc 5/04 pid loop.
My problem is i don't know where to begin as far as tuning it.
Where would i get initial values for the pid instruction and which values are more critical thatn others?
Max operating psi is about 1600 psi and high limit is 2500 psi low limit and output min is 0 psi.Would 1600 psi be my output cv% max?
How can i get values for gain kc,reset ti,rate rd,loop update,deadband.
Default control mode is E=SP-PV is this correct?
What about time mode default is sti. What is sti?
I have read the instruction help and i am still lost.
Can someone give me some direction please.
