| EXAMPLE: | |
|
|
|
|
|
|
|
| Process Variable = Flow | |
|
|
|
|
|
|
|
| Range of Flow = 0 to 250 Liters/Minute | |
|
|
|
|
|
|
|
| Actuation (Input 2) = 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 | |
|
|
|
|
|
|
|
|
| The control setpoint will be |
|
|
|
