Endress+Hauser silometer FMC 671 Z - Continuous Volume Measurement (Linearization)

10.2 Continuous volume measurement (linearization)
Start
Chapter 4, Section 4.1
- Constants for EC 37 Z/EC 47 Z or
EB 17 Z/EB 27 Z
- level is displayed at V0H0
Calibration
Chapter 4, Section 4.3
- After calibration level is
displayed at V0H0
Linearization
Chapter 5
- V0H0 displays volume
- Relays and analogue output must
be set in volume units
Set analogue output signal
Chapter 6
- Enter settings in the units selected
during calibration or linearization
Set relay parameters
Chapter 7
-both relay follow channel 1
Lock parameter matrix
Chapter 4, Section 4.6
Reset parameters: V9H5
Enter sensor constants
zero frequency V3H5
sensitivity V3H6
Select mode V8H0
1 = Level measurement
»Empty« calibration V0H1
»Full« calibration V0H2
For vessel linearization
Set linearization type V2H0
1 = horizontal cylinder*
2 = factory setting
3 = manual characteristic
For Option 1,
Enter tank diameter V2H7
Enter tank volume V2H8
Select output range V0H3
0 = 0…20 mA/0…10 V,
1 = 4…20 mA/2…10 V
Set output damping V0H4
Set 0/4 mA value V0H5
Set 20 mA value V0H6
Set output at fault V0H7
0 = –10% (–2 mA/–1 V)
1 = +110% (+22 mA/11 V)
2 = last measurement
Set switch point relay 1 V1H0
Set fail-safe mode V1H1
0 = Minimum
1 = Maximum
Set switching hysteresis V1H2
Set status at fault V1H3
0 = de-energises
1 = depends on V0H7
* If the calibration is made in volume units
check Section 5.1 for correct
linearization/calibration sequence
Assign relay 2 V1H9
1 = channel 1
Set switch point relay 2 V1H5
Set fail-safe mode V1H6
0 = Minimum
1 = Maximum
Set switching hysteresis V1H7
Set status at fault V1H8
0 = de-energises
1 = depends on V0H7
Lock parameter matrix V8H9
