Calibration steps
Disconnect the field
wiring
4/00
Use the following steps when calibrating an input.
Step
1 Find the minimum and maximum range values for your PV input range from
Table 7-1.
2
Disconnect the field wiring and find out what equipment you will need to
calibrate. DO NOT remove external resistor assemblies (if present).
3 Wire the calibrating device to your controller according to the Set Up wiring
instructions for your particular input.
4 Follow the calibration procedure given for Input #1, Input #2, or Input #3,
after the controller has warmed up for a minimum of 15 minutes.
Depending on which input (#1, #2, or #3) you are going to calibrate, tag
and disconnect any field wiring connected to the input terminals on the
rear of the controller.
Figure 7-1 shows the wiring terminal designations for Input #1, Input #2,
and Input #3.
