First you need to know: What is the output of the transmitter and what does it relate to?
You need to match the input range of the control to the output of the transmitter. If the transmitter is 4-20mA input then the control should be configured for an input of 4-20mA. Once you have that you need to match the scaling between the transmitter and the control.
Description
Example: If transmitters output is 4-20mA and 4mA is 0 Bar and 20mA is 30.0 PSI then use the following settings:
InPt: 4_20

All of the above is set in the control's configuration menu:
Description
Displayed Parameter | |
Input type and range | InPt |
Scale Range Upper Limit | ruL |
Scale Range Lower Limit | rLL |
Decimal Point Position | dPoS |
Example: If transmitters output is 4-20mA and 4mA is 0 Bar and 20mA is 30.0 PSI then use the following settings:
InPt: 4_20
ruL: 0
rLL: 30.0
dPoS: 1
