| Upper Display |
|
IN2 HIGH | INPUT 2 HIGH RANGE VALUE in engineering units | |
| (in engineering units) | is displayed for all inputs but can only be configured |
|
| for linear or square root transmitter characterization |
|
| See the example in IN1 HI. |
|
|
|
IN2 LOW | INPUT 2 LOW RANGE VALUE in engineering units | |
| (in engineering units) | is displayed for all inputs but can only be configured |
|
| for linear or square root transmitter characterization. |
|
| See the example in IN1 HI |
|
|
|
RATIO 2 | RATIO ON INPUT | |
| Floats to 3 decimal places | want on Input 1. |
|
|
|
BIAS IN2 | BIAS ON INPUT 2 — Bias is used to compensate | |
| (in engineering units) | the input for drift of an input value due to |
|
| deterioration of a sensor, or some other cause. |
|
| Select the bias value you want on Input 1. |
|
|
|
FILTER 2 | 0 to 120 seconds | FILTER FOR INPUT |
| No filter = 0 | provided for Input 1 to smooth the input signal. You |
|
| can configure the first order lag time constant from 1 |
|
| to 120 seconds. If you do not want filtering, enter 0. |

|
BURNOUT |
| BURNOUT PROTECTION (SENSOR BREAK) |
|
| provides most input types with upscale or downscale |
|
| protection if the input fails. |
| NONE | NO |
|
| Control Algorithm (such as the PV or RSP input |
|
| parameter), then the |
|
| (selected in the CONTROL Set up Group) is applied |
|
| when a failed input is detected (does not apply for an |
|
| input out of range). Diagnostic message IN2 FAIL is |
|
| intermittently flashed on the lower display. |
| UP | UPSCALE BURNOUT will force the Input 2 signal to |
|
| the full scale value when the sensor fails. Diagnostic |
|
| message IN2 FAIL intermittently flashed on the lower |
|
| display. |
|
| The controller remains in Automatic control mode |
|
| and adjusts the controller output signal in response |
|
| to the full scale Input 2 signal developed by the |
|
| Burnout circuitry. |
| DOWN | DOWNSCALE BURNOUT will force the Input 2 |
|
| signal to the lower range value when the sensor |
|
| fails. Diagnostic message IN2 FAIL intermittently |
|
| flashed on the lower display. |
|
| The controller remains in Automatic control mode |
|
| and adjusts the controller output signal in response |
|
| to the lower range Input 2 signal developed by the |
|
| Burnout circuitry. |
