|
| This selection lets you instruct the controller | |||
|
|
|
|
| E H | 1 |
|
| ||
|
|
|
|
|
|
| to characterize a linear input to represent a | |||

| If input 1 is a 4 to 20 mA signal, but the | |

|
| NICL | 12 |
|
| signal represents a type K H thermocouple, | |

|
|

| then configure K H and the controller will | |
|
|
|
|
| S | 14 |
|
| characterize the 4 to 20 mA signal so that it | |
|
|
|

|
|

|
| Actuation (Input 1) = 4 to 20 mA | |

|
| Characterization (XMITTER) = LINEAR | |
|
|
|
|
|
|
|
|
| Set IN1 HI display value to 250 | |
|
|
|
|
|
|
|
|
| Set IN1 LO display value to 0 | |
|
|
|
|
|
|
|
|
| Then 20 mA = 250 Liters/Minute | |
|
|
|
|
|
|
|
|
| and 4 mA = 0 Liters/Minute | |
