10.2 Mounting the sensor
Installation in suitable assembly is required (depending on the application)
WARNING
L
Electrical voltage
In the event of a fault, non-grounded metallic assemblies may be under voltage and then are
not touchable.
‣
When using metallic assemblies and installation equipment, observe the national
grounding provisions.
For a complete installation of a measuring point, proceed as follows:
1. Install a retractable or a flow assembly (if used) into the process.
2. Connect the water supply to the rinse connections (if you use an assembly with cleaning
function).
3. Install and connect the oxygen sensor.
NOTICE
Installation error
Cable open circuit, loss of sensor due to cable separation, unscrewing of spot cap
‣
Do not install the sensor suspended from the cable.
‣
Screw the sensor into the assembly so that the cable is not twisted.
‣
When installing or uninstalling, hold the sensor body tightly. Only turn at the hexagonal
nut on the armored coupling. Otherwise you might unscrew the spot cap. This will then
remain in the assembly or process.
‣
Avoid exerting excessive tensile force on the cable (e.g. from jerky pulling).
‣
Select an installation location that is easy to access for later calibrations.
‣
Observe the instructions for installing sensors in the Operating Instructions for the
assembly used.
10.3 Post-installation check
• Are the sensor and cable undamaged?
• Is the orientation correct?
• Is the sensor installed in an assembly and is not suspended from the cable?
• Avoid the penetration of moisture by fitting the protective cap to the immersion assembly.
