Honeywell UDC3200 manual RV Limit, Segerr, Cal Mtr, Curfail, Axfail

Lower	Reason for Failure
Display
PV LIMIT	PV out of range.
	PV = INP1 x RATIO1+ INP1 BIAS
RV LIMIT	The result of the formula shown below is
	beyond the range of the remote variable.
	RV = INP2 X RATIO + BIAS
SEGERR	Setpoint Program start segment number is
	less than ending segment number.
CAL MTR	Slidewire calibration never performed.
SW FAIL	Position Proportional slidewire input failure.
SOOTING	Percent Carbon falls outside 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.
CURFAIL	Current Output is less than 3.5 mA.
AXFAIL	Auxiliary Output is less than 3.5 mA.

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 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.
