1.13 Maintenance and inspection safety information
Warning – Risk to persons!
When the housing cover is open, EMC and protection against contact are suspended. There
are electric circuits within the housing which pose a contact risk.
The auxiliary power must be switched off before opening the housing cover.
Warning – Risk to persons!
The inspection screw (for draining condensate fluid) for devices
≥
DN 450 can be under
pressure. The fluid which spurts out can cause severe injuries.
Depressurize pipes before opening the inspection screw.
Corrective maintenance work may only be performed by trained personnel.
• Depressurize the device and adjoining lines or containers before removing the device.
• Check whether hazardous materials are used as materials to be measured before opening
the device. Residual amounts of hazardous material may still be present in the device and
could escape when the device is opened.
• As far as provided in the scope of the operational responsibility, check the following items
through a regular inspection:
the pressure-carrying walls / lining of the pressure device
the measurement-related function
the leak tightness
the wear (corrosion)
1.14 Returning devices
Use the original packaging or suitably secure shipping containers if you need to return the
device for repair or recalibration purposes. Fill out the return form (see the Appendix) and
include this with the device.
According to EC guidelines for hazardous materials, the owner of hazardous waste is
responsible for its disposal or must observe the following regulations for shipping purposes:
All devices delivered to ABB Automation Products GmbH must be free from any hazardous
materials (acids, alkalis, solvents, etc.).
Rinse out and neutralize hazardous materials from all hollow spaces such as between meter
tube and housing. For flowmeters larger than DN 400, the service screw (for draining
condensate fluid) at the lower point of the housing must be opened to dispose of hazardous
substances and to neutralize the coil and electrode chamber. These activities must be
confirmed in writing using the return form.
