Honeywell UDC3200 ユーザーズマニュアル

The UDC3200 performs ongoing background tests to verify data and memory integrity.  If 
there is a malfunction, a diagnostic message will be displayed (blinking) in the lower 
display. In the case of simultaneous malfunctions, the messages will appear in sequence in 
the lower display. 

Diagnostic messages may be suppressed (stop the blinking) by pressing the RUN/HOLD 
key. The messages will still be available for viewing by pressing the LOWER DISPLAY 
key. 

Unable to write to non-volatile memory. 
Anytime you change a parameter and it is 
not accepted, you will see E FAIL. 

1.  Check the accuracy of the parameter and re-enter. 

2.  Try to change something in configuration. 

3.  Run through Read STATUS tests to re-write to 

EEPROM. 

This error message shows whenever the 
controller goes into a failsafe mode of 
operation. This will happen if: 
 

•  RAM test failed 

 

•  Configuration test failed 

 

•  Calibration test failed 

 

•  Burnout configured for none and 

the input failed. 

1.  Run through STATUS check to determine the 

reason for the failure. 

2. Press the SET UP key until STATUS appears in 

the lower display. 

3. Press the 

FUNCTION key to see whether the tests 

pass or fail, then run through the STATUS codes a 
second time to see if the error cleared. 

Input 1 out of range. The process input is 
outside the range limits. 

 

1.  Make sure the range and actuation are configured 

properly. 

2.  Check the input source. 

3.  Restore the factory calibration. 

4. Field calibrate. 

Two consecutive failures of input 1 
integration; i.e., cannot make analog to 
digital conversion. This will happen if: 
• Upscale or Downscale burnout is 

selected and the input is open 

• Input not configured correctly for the 

sensor being used  

• Input source is grossly out of range.  

1.  Make sure the actuation is configured correctly. 

See Section 3 - Configuration. 

2.  Make sure the input is correct and that it has not 

burned-out (opened). 

3.  Check for gross over-ranging with a multimeter.  

4.  Restore factory calibration. 

Input 2 out of range. The remote input is 
outside the range limits. 

Same as INP1RNG above. 

Two consecutive failures of input 2 
integration. i.e., cannot make analog to 
digital conversion. 

Same as INP1FAIL above. 

• 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.
