Locating Errors
In the status file, 2 words per loop provide error codes for their
corresponding loop. The first word for each loop indicates
configuration-block and gains-block errors for that loop.

of the
status block
A nonĆzero value in
these two digits
indicate an error in the
gains block
A nonĆzero value in
these two digits
indicate an error in the
configuration block
Example: If a value 4713 is diplayed, the 47 in the upper
pair of digits would indicate an error in the gains block and
the 13 in the leastĆsignificant pair of digits would indicate an
error in the configuration block

A word in the configuration 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
6
is xx14, word
14
(cool maximum cycle time) of the loopĆ2
configuration block has an outĆofĆrange value,
00xx
No error detected in gains block.
1xx
thru
57xx
A word in the gains block has an outĆofĆrange value.
Locate the specific word by the value in the 3rd and 4th
leastĆsignificant decimal digits of the status word.
(value = word)
•
Example: If the value in word
9
is 14xx, word
14
(loopĆ2 cool derivative gain) of the gains block has
an outĆofĆrange value,
