PV LIMIT
PV out of range.
PV = INP1 x RATIO1+ INP1 BIAS
The result of the formula shown below is
RV LIMIT
beyond the range of the remote variable.
RV = INP2 X RATIO + BIAS
SEGERR
Setpoint Program start segment number is
less than ending segment number.
Slidewire calibration never performed.
CAL MTR
Position Proportional slidewire input failure. Check the slidewire.
SW FAIL
Percent Carbon falls outside sooting
SOOTING
boundary
TCx WARN
Thermocouple on Input x (1 or 2) is
starting to burnout.
TCxFAIL
The Thermocouple on Input x (1 or 2) is in
imminent danger of burning out.
Current Output is less than 3.5 mA.
CURFAIL
AXFAIL
Auxiliary Output is less than 3.5 mA.

Reason for Failure
UDC3200 Universal Digital Controller Operator Manual
How to Correct the Problem
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
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.
Check SP Program configuration, subsection 3.4 Set
up Group SPPROG function prompts "STRSEG" and
"ENDSEG".
Field Calibrate the slidewire.
Check process for correct operation.
This diagnostic message means that the controller
has detected that the thermocouple is starting to
burnout. This error message may also be created if
the resistance of the wires used to connect the
thermocouple to the instrument is above 100 ohms.
This diagnostic message means that the controller
has detected that the thermocouple will soon fail. User
should consider replacing the thermocouple as soon
as possible. This message will also be generated if the
resistance of the wires used to connect the
thermocouple to the instrument is above 180 ohms.
The current output is open circuit. Check the field
wiring.
The auxiliary output is open circuit. Check the field
wiring.
