6.1 Maintenance
For systems in hazardous areas, regular checks are required in order to maintain the proper
condition. The manufacturer recommends the following maintenance measures:
•
Check the housing, the cable entry and the feed lines for corrosion and/or damage.
•
Check the process connection and the piping connections for leakage.
•
Check the entire sensor for dust deposits.
6.2 Dismantling
In order to prevent injury or material damage when replacing the sensor, always observe the
following points:
•
Before dismantling the electrical connecting lines of the device, ensure that all the cables
leading to the sensor are de-energised themselves and to the reference potential of the
explosive area.
•
All the relevant process pipes or containers must be depressurised before dismounting the
sensor.
•
If the process pipes or the container contain products that are harmful to the environment or
to health, implement the appropriate safety measures before dismantling the sensor.
•
Replace all the seals when reinstalling the device in the process pipe or container.
CAUTION!
Maintenance measures of a safety-relevant nature within the meaning of explosion protection
may only be carried out by the manufacturer, his authorised representative or under the
supervision of authorised inspectors.
