•
The LBA detection time is automatically set by auto-tuning (except in
heating and cooling control).
•
If the optimum LBA detection time cannot be obtained by auto-tun-
ing, set the time in the “LBA detection time” parameter (level 2
mode).
•
Calculate the LBA detection time as follows:
(1) Set output to maximum.
(2) Measure the time it takes for the input change width to reach the
LBA detection width (factory setting: 0.2% FS).
PV
0.2%FS
Measurement time Tm
LBA detection time = Tm x 2
Output
Time
(3) Take a value twice that of the measurement time as the LBA detec-
tion time.
