2) When "dP" or "CP" or O2 are selected as the controlled

variable, this filter can affect the control action, the alarms,
the SMART algorithm and the process variable retransmission.

C.D07 - Auxiliary input function

Lower display: A.In.F
Range: nonE = Input not used
CO = Input used for CO measurement
rSP = Input used as remote set point
Available: Always
Note:The scalable for CO measurement is fixed from 000 to 100
When CO input is not used the CO value will be set to 20
The scalable for rSP measurement is fixed to:
0.00 / 2.00 if carbon potential is selected as primary control variable or
0 /100 °F (-18 / 40 °C) if dew point is selected as primary control variable or
0 / 1500 if sensor output in mV is selected as primary control variable
0.0/ 25.0 if oxygen value is selected as primary control variable

C.D08 - Auxiliary input type selection

Lower display:

A.In.t

Range:

0-20 = 0÷20 mA

4-20 = 4÷20 mA

0- 5 = 0÷ 5 V

1- 5 = 1÷ 5 V
0-10 = 0÷10 V
2-10 = 2÷10 V

C.D05 - Temperature input offset adjustment

C.D05 - Temperature input offset adjustment
Upper display: CnF.1
Lower display: OFSt
Range: from -500 to 500
NOTE

NOTE

NOTE: The offset value is algebraically added to temperature

input value.

C.D06 - Filter on temperature input value

C.D06 - Filter on temperature input value
Upper display: CnF.1
Lower display: tP.FL
Ranges: from 0 (no filter) to 8 seconds.

NOTES:

NOTES:
1) This is a first order digital filter applied to the temperature
