CAUTION!
Physical injuries and damage to property and the environment
EN
If faults cannot be eliminated by means of the listed measures, the pressure transmitter must be taken
out of operation immediately.
▶
Ensure that pressure or signal is no longer present and protect against accidental commissioning.
▶
Contact the manufacturer.
▶
If a return is needed, please follow the instructions given in chapter 8.2 "Return".
WARNING!
Physical injuries and damage to property and the environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen) and also with refrigeration plants and compressors,
there is a danger of physical injuries and damage to property and the environment.
▶
Should a failure occur, media with extremely high temperature and under high pressure or vacuum
may be present at the instrument.
▶
For these media, in addition to all standard regulations, the appropriate existing codes or regulations
must also be followed.
▶
Wear the requisite protective equipment.
In the event of any faults, first check whether the pressure transmitter is mounted correctly, mechanically and
electrically.
If complaint is unjustified, the handling costs will be charged.
