17.Maintenance and repair
Before carrying out any maintenance or service activities,
the engineer concerned must ensure that the analyser is
disconnected from the electrical supply of power!
• Maintenance of the analyser should be performed by
qualified personnel, and the frequency of maintenance may
vary as a result of operating experience.
• Any used spare parts must be specified as M&C spare parts.
• Routine maintenance of the PMA100-L oxygen analyser
is limited to frequently checking the zero and span point
cali-bration. If the values are not correct, the instrument
should be recalibrated according to the procedure as
outlined in this instruction manual.
• In the event of an incorrect reading of the analyser or a
system failure make certain that the sampling system is in a
good condition and that all sample handling components
are working properly.
• Check that gas cooler, filters, condensate drain or other
components are not blocked with dirt or any foreign matter.
Ensure that the sample gas is connected correctly and is
flowing properly through the system, and make a visual
inspection of the analyser for loose or leaking connections.
Note!
It is strictly recommended that the repair of the analyser
should be performed by high qualified as well as experienc-
ed personnel, and that any spare part which is used should
be specified as M&C spare part !
