Note!
Make sure you comply with the instructions for installing sensors. You will find them in
the Operating Instructions for the assembly used.
Installing a
measuring point For a complete installation of a measuring point, proceed as follows:
1. Installing an retractable or an flow assembly (if used) into the process.
2. Water connection to the rinse connections (if you use an assembly with cleaning
function).
3. Installing and connecting the oxygen sensor.
4. Installing an immersion or an suspension assembly (if used) into the process.
"
Caution!
•
For immersed operation, the sensor must be installed in an immersion assembly (e. g.
CYA 611).
Do not install the sensor suspended from the cable.
•
Screw the sensor into the assembly so that the cable is not twisted.
•
Avoid exerting excessive tensile force on the cable (e.g. from jerky pulling).
•
Select the installation location so that there is easy access for later calibration.
#
Warning!
When using metallic assemblies and installation equipment, comply with national
grounding regulations.
Pre-installation
For immersed operation, install the individual modules away from the basin on a solid
base. Only carry out the final installation at the intended installation location.
Placing
Select the installation location so that there is easy access for later calibration. Make
sure that upright posts and assemblies are secured safely and vibration-free. For
immersed operation in an activated sludge basin, select an installation location which
produces a typical oxygen concentration.
