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. Refer to "To check the filter" below and “To replace the
filter” on page B-3 for instruction.
Regular SCS status check
1. Open the SCS door.
2. Read and record the flow meter settings while the gas is flowing.
3. Close the SCS door.
4. Compare the current readings with the past readings to determine
any variations. Reading levels should remain consistent.
5. If reading levels decrease, check the filters.
To check the filter
1. Shut down the system following the procedure in “Shutting Down
the SCS” on page 3-10.
2. Inspect, repair or replace the filter as required. Refer to “To replace
the filter” on page B-3, if required.
3. Restart the system.
The system must be taken out of service during any cleaning of
the sample transport line.
Do not leave the SCS door open any longer than absolutely
necessary. SpectraSensors recommends no more than 60
seconds. Opening the door may affect the temperature reading
until the temperature is stabilized.
