Step Procedure
6
Check compressed-air tank (if present) for visible damage.
7
Check probe pipe for signs of wear, e.g. polished metal surfaces.
This applies particularly after start-up, after changing the alignment
of the probe, etc. The calcinator outlet measuring point is particular-
ly affected.
If you observe signs of wear, you must reposition the gas sampling
probe in the process gas flow; if you have any questions regarding
repositioning the probe, contact ABB Service.
Check the wall tube for clogging and deposits at regular intervals and clean if
necessary.
Note: Inserting the gas sampling probe when the wall tube is clogged can lead to
damage to the probe. The same applies to re-inserting the gas sampling probe
after prolonged standstill of the gas sampling system.
