Auto tuning is the function that controller is set up most suitable PID number automatically.
Auto tuning is calculated with P, I, D as a cycle and amplitude.
Auto tuning is possible at Fix RUN only and set P, I, D vaule automatically.
Auto Tuning Action
Setting
OPER. MODE = FIX RUN
INPUT = TEMP(PT_1)
RANGE = -50.00℃ ~ 150.00
TEMP AUTO TUING POINT = 0.10%
EUS 0.10% = 0.2℃
SP = 50.0℃
OL = 0.0%
OH = 100.0%
Auto Tuning
Action
The caution about Auto Tuning.
Though SP has changed at Auto Tuning, Tuning Point is not changed. And changed SP start
control as TSP(Target SP) after bring Auto Tuning to an end.
If Burn Out is occurred at Auto Tuning, Auto Tuning is stopped.
Keep up previous P, I, D setting value.
If two cycle time is over 24 hours, Auto Tuning is stopped.
Though you can change P, I, D setting value at Auto Tuning, its value is changed
re-calculable value at Auto Tuning is stopped.
If Auto Tuning is stopped by compulsion, P,I,D value keep up previous setting value.
The order of the Auto Tuning
1 Auto Tuning of the temperature side.
2 Auto Tuning of the humidity side.
