WIKA operating instructions electronic contact, model 830 E 9
4. Design and function / 5. Transport, packaging, storage
The familiar advantages with inductive contacts, such as an especially safe
contact operation, no wear at all by proximity contact operation as well as
virtually no reaction on the measuring system, thus enabling the accuracy of the
indication, are used in this context, too.
An additional control unit is not required.
The electronic contact with 2- or 3-wire design is realised with PNP output. The
operating voltage is 10 ... 30 V DC. The maximum switching current is 100 mA.
The model 830 E electronic contact is not intrinsically safe and therefore not
suitable for applications in potentially explosive atmospheres!
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.
5. Transport, packaging and storage
5.1 Transport
Check instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g.
change in installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: In accordance with measuring instrument
