Honeywell UDC2500 ユーザーズマニュアル

•  Apply power and allow the controller to warm up for 30 minutes before you calibrate. 
•  Please read Subsection 5.4 – Input 1 Set Up Wiring before beginning the procedure. 
•  Make sure you have LOCK set to NONE. See Subsection 3.4 - Tuning Set Up 

Group. 

•  See Table 5-1 for Voltage vs. Resistance equivalents or 0 % and 100 % range values. 

For linear inputs, avoid step changes in inputs. Vary smoothly from initial value to final 100 % value. 

 

The calibration procedure for Input #1 is listed in Table 5-10. The numeric codes are also 
listed. 

Step 

Enter Calibration 
Mode 

 

until you see 

 = CAL ( 

 = INPUT1 (10000) 

 

 

You will see: 

 = DIS ( 0 ) 

 = CALIN1 (10001) 

 

 

The calibration sequence is enabled and you will see: 

 = BEGN ( 1 ) 

 = CALIN1 (10001) 

At the completion of the sequence, the selection 
automatically reverts to disable. 

Calibrate 0 % 

 

You will see: 

 = APLY ( 2 ) 

 = IN1ZRO (10002) 

•  Adjust your calibration device to an output signal equal 

to the 0 % range value for your particular input sensor. 
See Table 5-1 for Voltage, Degrees, or Resistance 
equivalents for 0 % range values. 

•  Wait 15 seconds, then go to the next step.
