Installing a measuring point
WARNING
!
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 errors
Cable breakage, loss of the sensor, unintended unscrewing of the membrane cap
►
Do not install the sensor suspended from the cable.
►
Screw the sensor into the assembly so that the cable is not twisted.
►
Mounting or dismounting the sensor: hold the sensor body, only turn the threaded plug-in head
while screwing the sensor in or out of the assembly. Otherwise you could unscrew the sensor’s
membrane cap. It will remain in the assembly resp. in the process then.
►
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.
