Subject to chance without notice
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -20 ... +80 °C
■
Humidity: 45 ... 75 % relative humidity (no condensation)
In order to protect the diaphragm, mount the protection cap before storing the instrument.
WARNING!
Before storing the instrument (following operation), remove any residual media. This is of particular
importance if the medium is hazardous to health, e.g. caustic, toxic, carcinogenic, radioactive, etc.
6. Commissioning, operation
CAUTION!
Only use the pressure switch if it is in perfect condition with respect to safety.
Check the following points before commissioning:
■
Check the diaphragm for any visible damage, since this is a safety-relevant component.
■
Leaking fluid is indicative of damage.
6.1 Making the mechanical connection
■
Remove the protection cap not until shortly before mounting. During installation, ensure that the diaphragm
is not damaged.
■
The sealing faces at the instrument always have to be clean.
■
Only ever screw in, or unscrew, the instrument via the spanner flats. Never use the case as a working surface.
■
The correct torque depends on the dimensions of the pressure connection and the gasket used (form/material).
■
When screwing in, do not cross the threads.
■
Never loosen sealed filling screws on the measuring instrument.
■
For installation, in accordance with the fitting and flange standards the appropriate fastenings, such as
screws, nuts or clamp rings, must be used.
■
For flange mounting, only use sealings with a sufficiently large inner diameter and centre them; contact with
the diaphragm leads to measuring errors.
