Reason for Failure
How to Correct the Problem
IN2_FL
Two consecutive failures of input 2
integration. i.e., cannot make analog to
digital conversion.
Same as IN1FL above.
CNFERR
• PV low limit is > PV high limit
• SP low limit is > SP high limit
• Output low limit > Output high limit
1. Check the configuration for each item and
reconfigure if necessary.
PV LIM
PV out of range.
PV = INP1 x INP1 BIAS
1. Make sure the input signal is correct.
2. Make sure the Ratio and Bias settings are
correct.
3. Recheck the calibration. Use Bias of 0.0
RV LIM
The result of the formula shown below
is beyond the range of the remote
variable.
RV = INP2 X RATIO + BIAS
1. Make sure the input signal is correct.
2. Make sure the Ratio2 and Bias2 settings are
correct.
3. Recheck the calibration. Use a Ratio2 of 1.0
and a Bias2 of 0.0.
SEGERR
Setpoint Program start segment
number is less than ending segment
number.
1. Check SP Program configuration, subsection
4.6 Set up Group SPPROG function prompts
“STRSEG” and “ENDSEG”.
