Locationg Errors
Appendix B
B-2
The second word for each loop indicates dynamic-block and auto-tuning
errors for that loop.
Display of integer value in word 4,
7, 10, 13, 16, 19, 22, or 25 of the
status block
A nonĆzero value in
these two digits
indicate an error in the
autoĆtuning process
A nonĆzero value in
these two digits
indicate an error in the
dynamic block
Example: If a value 6724 is diplayed, the 67 in the upper
pair of digits would indicate an error in autoĆtuning and the 24
in the leastĆsignificant pair of digits would indicate an error in
the dynamic block
If This Word of
Status Block:
Contains This
Value:
The Error is:
4 (loop 1)
7 (loop 2)
xx00 No error detected in dynamic block.

A word in the dynamic block has an outĆofĆrange value
or incompatible bit selection. Locate the specific word
by the value in the 2 leastĆsignificant decimal digits of
the status word. (value = word)
• Example: If the value in word 13 is xx17, word 17
(loopĆ4 manual output value) of the dynamic block
has an outĆofĆrange value,
00xx No error in autoĆtuning the loop.
65xx AutoĆtuning terminated because of thermal runaway.
66xx AutoĆtuning terminated because the change in PV
(since initial PV temperature) has exceeded 200 .
67xx AutoĆtuning terminated because PV is within 50 of
setĆpoint.
