MAINTENANCE

When working during operation:
High surface temperatures!
Touching the surfaces can result in burns. Wear protective gloves.
Aggressive condensate possible!
Wear safety goggles and suitable protective clothing.
The requirements of VDE 0100 and its associated standards and regulations
must be observed when erecting and servicing high-voltage power installations
Warning
with rated voltages of up to 1000 V!
Work on the gas sample probe must only be carried out when the environment
has been declared as non-hazardous area, i.e. it is free of explosive
atmospheres.
The process side must also be declared as non-hazardous area – free of
explosive atmospheres – before the filter chamber is opened.
Warning
The back-purging unit must be switched off before the filter chamber is opened.
The gas sample probe with preliminary filter and internal filter must be checked
for temperature and dust deposits in suitable intervals of time depending on the
process conditions. Dust layers of more than 5 mm [≈ 0.2"] must be removed
immediately. The filters must be checked for damage and replaced if necessary.
Also remove the dust deposits under the cover.
The probe must be shut down when the respective maximum surface
temperature is exceeded.
The system and process-specific safety measures must be observed for all maintenance work.
Maintenance intervals cannot be recommended. They must be determined on site depending on the
specific application and process conditions. An indication of the need for maintenance work on the
probe can be a steady decline in the sample gas flow to the analyser system.
Check the probe every 3 years latest.
The testing steps are described as follows.
