NOTES
1. Avoid applying the auto-tuning to the following processes.
(a) The process must not be disturbed due to temporary ON-OFF
control output from CN4800.
(b) Process featuring very quick response such as pressure/flow
rate process.
(c) Process where overshoot must not be generated
2. Auto-tuning cannot be executed under the following conditions. If
the auto-tuning is already being executed, stop it.
(a) Manual operation
(b) Measured value (PV) error occurring
(c) When the set value (SV) has changed by more than 0.5%FS
per 0.5 second during auto-turning
(d) Auto-tuning not terminated within 12 hours
3. Do not execute auto-tuning when the ramp soak function is being
used (i.e. when the parameter “
” is not
), since it
may result in incorrect tuning.
4. When the operation condition is changed, restart the auto-tuning
5. When the auto-tuning terminates abnormally, the PID value takes
the value prior to auto-tuning, in such cases as abnormal
termination of auto-tuning. The same applies when the auto-tuning
command is switched to
during auto-tuning.
