Honeywell UDC3200 ユーザーズマニュアル

PV out of range. 
PV = INP1 x RATIO1+ 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 

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. 

Setpoint Program start segment number is 
less than ending segment number. 

Check SP Program configuration, subsection 3.4 Set 
up Group SPPROG function prompts “STRSEG” and 
“ENDSEG”. 

Slidewire calibration never performed. 

Field Calibrate the slidewire. 

Position Proportional slidewire input failure.

Check the slidewire. 

Percent Carbon falls outside sooting 
boundary 

Check process for correct operation. 

Thermocouple on Input x (1 or 2)  is 
starting to burnout. 

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. 

The Thermocouple on Input x (1 or 2) is in 
imminent danger of burning out. 

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. 

Current Output is less than 3.5 mA. 

The current output is open circuit. Check the field 
wiring. 

Auxiliary Output is less than 3.5 mA. 

The auxiliary output is open circuit. Check the field 
wiring.
