staff qualification
Improper handling can result in considerable personal injury and damage to equipment.
The activities described in these operating instructions may only be carried out by skilled
staff who have the appropriate qualifications. For installation and starting of the sensor,
the relevant regulations and directives of the country and the norms must be observed.
Especially during installation of the sensor, it is possible, depending on the use, to come
into contact with aggressive media. The safety instructions must be observed. There will
be danger to life if live parts are touched. Electrical installation and commissioning may
only be carried out by qualified and skilled personnel.
special hazards
Residual media in dismantled devices can result in a risk to personnel, the environment
and equipment. Sufficient precautionary measures must be taken here. Do not use the
instruments in safety or emergency stop devices. Incorrect application or operation of the
instrument can lead to injuries. Depending on the application, aggressive media with
extreme temperatures and high pressure or vacuum may be present at the instrument in
the event of a fault. We recommend installing and removing the device only at ambient
temperature and in a pressureless mode.
hazards when operating the device
Our devices have a very high protection class when properly mounted and installed. When
cleaning your system with high-pressure cleaners, steam cleaners etc., make sure that
both the cover and the cable screw or M12 connector are not directly exposed to the
pressure jet. If the temperature falls below the dew point, condensation may form in the
connection chamber of the device. In such extreme applications, contact our sales and
technical support before commissioning.
