- Please read the product description prior to set-up of the unit. Ensure that the
product is suitable for your application without any restrictions.
- The unit conforms to the relevant regulations and EC directives.
- Improper or non-intended use may lead to malfunctions of the unit or to
unwanted effects in your application.
- That is why installation, electrical connection, set-up, operation and
maintenance of the unit must only be carried out by qualified personnel
authorized by the machine operator.
- The capacitive sensor detects without contact metals, almost all plastics, glass,
ceramics, wood, paper, oils, greases, water and all hydrous materials and
indicates their presence by providing a switched signal.
