Meaning or cause of fault
Possible solutions
0
No trial performed or trial interrupted by
switching to automatic operation
1
Interrupted:
Wrong direction for operation of
the manipulated variable, X does not change to
direction W.
Change operating direction
2
Terminated:
Self optimization has been successful (reversal point found; estimate confirmed )
3
Interrupted:
The manipulated variable does not react or is
too slow (alteration of
"
x less than
1% in 1 hour)
Close down control circuit
4
Terminated:
(deep reversal point)
Interrupted:
Stimulus too low (reversal point
found; estimate not confirmed)
In crease manipulated variable
dYopt
5
Interrupted:
Optimization interrupted due to
risk of exceeding set value
Increase interval between actual value
( X ) and set value (W ) at start
6
Terminated
: Optimization interrupted due to risk of exceeding set value (reversal point not yet reached;
estimate not confirmed).
7
Interrupted:
Manipulated variable interval too small
"
Y < 5%
Increase
Ymax
or set
YOptm
to a
smaller value.
8
Interrupted:
Set value reserve too small or
set value exceeded while
PiR monitoring is running.
Change set settling value
YOptm
.
g
If the control process is not as desired in spite of self optimization, steps can also be taken as per
Section 7 (Page 17, empirical optimization).
