2. Monitor the SCS enclosure thermometer during the warm-up period
for
5-8 hours
to confirm that the sample system enclosure
temperature does not exceed 65

C.
To start up the field pressure reducing station
1. Open the low pressure flare or atmospheric vent header shut-off
valve for the relief valve vent from the field pressure reducing
station.
2. Slowly open the sample probe process shut-off valve at the sample
supply tap.
3. Slowly open the pressure regulator at the field pressure reducing
station (adjustment knob turned clockwise) and set the pressure
regulator to the specified pressure (refer to Appendix A).
Allow the system a
minimum of 5 to 8 hours
(preferably
overnight) to ensure stabilization. During this time, the system
will emit a variety of alarms - this is normal. Contact Service if the
alarms do not resolve themselves by the end of the warm-up
period. Refer to “Service Contact” on page B-31.
The entire analyzer system is calibrated for operation at the
enclosure temperature specified. Measurements should be
considered valid only when the enclosure is at the specified
temperature.
If the SCS enclosure exceeds 65

C, damage to the system could
occur. Shut down the system immediately .
An optional field pressure reducing station and/or sample probe
may be provided by SpectraSensors or through a third party. This
is not included in a standard configuration.
The process sample at the sample tap may be at a high pressure.
Use extreme caution when operating the sample probe isolation
valve and field pressure reducing regulator.
The low pressure flare or atmospheric vent header shut-off valve
must be “car-sealed” open and tagged as a relief valve vent so
that this valve will not be closed unless the SCS is not in
operation.
