Input Calibration

5.5 Input 1 Calibration Procedure

Preliminary Steps
• 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.
CAUTION
For linear inputs, avoid step changes in inputs. Vary smoothly from initial value to final 100 % value.
Procedure
The calibration procedure for Input #1 is listed in Table 5-10. The numeric codes are also
listed.

•
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.
