Measured variable fluoride
Fluoride Measured Variable
When measuring fluoride as the measured vari‐
able, the sensor signal is converted into a 4 -
20 mA signal by a FPV1 or FP100V1 meas‐
uring transducer, depending on the measuring
range. The measuring transducer is connected
to the controller's mA input. The REFP-SE ref‐
erence sensor is connected to the measuring
transducer using a coaxial cable with an SN 6
plug.
FPV1 measuring transducer: Measuring range
0.05 ...10 mg/l.
FP100V1 measuring transducer: Measuring
range 0.5 ... 100 mg/l.
Measuring range of the measuring transducer
Select the measuring range. The measuring
range is printed on the nameplate of the meas‐
uring transducer. An incorrect measuring range
will lead to an incorrect measurement.
Configuring measured variables
Temperature compensation
This function is used for compensation of the
temperature influence on the measurement.
This is only necessary with pH and fluoride
measurement and when chlorine dioxide is
measured using a CDP sensor.
Temperature: [Off] / [Manual] / [Automatic]
[Off] switches the process temperature
n
setting off
[Manual] enables the process temperature
n
to be manually specified, which makes
sense with constant temperatures
[Automatic] uses a measured process tem‐
n
perature. Automatic measurement of the
temperature using the temperature sensor,
e.g. Pt1000. With pH, temperature com‐
pensation can be switched
in the menu.
9.1.7
Peracetic acid
Peracetic acid measured variable
Peracetic acid as a measured variable is meas‐
ured via one of the two mA sensor inputs. Tem‐
perature compensation is performed in the
sensor. An additionally connected temperature
sensor is only used for display and data
recording with a data logger and can be issued
on a mA-output via field bus or web server.
Measuring range of the sensors
Select the measuring range. The measuring
range is given on the sensor nameplate. An
incorrect measuring range leads to an incorrect
measurement.

Questions and answers
How do I calibrate measuring channel
To calibrate a measuring channel on a ProMinent diaLog DACb:
1. Select the channel to be calibrated (e.g., Channel 1: Chlorine).
2. Access the [Calibration] menu from the continuous display.
3. Follow the on-screen instructions to perform the calibration.
4. Adjust the value using the appropriate buttons if prompted.
5. Import the calibration result into the controller memory by pressing the confirmation button.
6. The controller will return to the continuous display and use the new calibration values.
If calibration values are outside specified limits, an error message appears, and the calibration is not saved. In that case, check conditions, correct any issues, and repeat the calibration. Each measuring channel must be calibrated separately.
