Preventive and on-demand maintenance will be required when components
and parts deteriorate or fail as a result of continuous use. The performance of
the entire SCS and individual components should be monitored regularly so
that maintenance may be performed on a scheduled basis in order to prevent
a failure that could take the system out of operation.
The SCS is designed for convenient removal and replacement of component
parts. Complete spare components should always be available. In general, if a
problem or failure occurs, the complete part should be removed and replaced
to limit system down time. Some components may be repaired (replacement
of seats and seals, etc.) and then reused.
If the sample supply line does not appear to completely clear during normal
operation, it may be necessary to clean the sample transport line to remove
any liquid that may adhere to the wall of the tubing. The sample transport line
should be purged dry with air or nitrogen before the system is placed back in
operation.
If liquid makes it into the analyzer SCS, a filter element may become
obstructed leading to a decreasing supply pressure or bypass flow. If
obstruction of a filter is observed, the filter should be cleaned and the filter
element replaced.
ToperformregularSCSstatuscheck
1. Read and record the flow meter settings while the gas is flowing.
2. Compare the current readings with the past readings to determine
any variations. Reading levels should remain consistent.
3. If reading levels decrease, check the filters.
Tocheckfilters
1. Shut down the system following the procedure in “Shutting Down
the SCS” on page 4-9.
2. Inspect, repair or replace the filter as required.
3. Restart the system. Refer to “Starting up the full-featured
sample system” on page 4-5 or “Starting up the Simplified
Sample System” on page 4-7.
The system must be taken out of service during any cleaning of
the sample transport line.
