Safety Manual 4–1
4 - EQUIPMENT OPERATION
This chapter provides an overview of safety operational instructions for the
SS2100i-1.
Firmware Version
Each SpectraSensors analyzer operates based on its own version of firmware.
The firmware version for each analyzer is listed in the system calibration
report, and displays upon start-up of the analyzer. Detailed operation
instructions are provided in the firmware manual shipped with the purchased
analyzer or by model type on the SpectraSensors website
(
www.spectrasensors.com).
Intermittent Operation
If the analyzer is to be stored or shut down for a short time period, follow the
instructions for isolating the measurement cell and sample conditioning system
(SCS).
Cleaning and Decontaminating the Analyzer
If the analyzer has been installed and or operated (even for purposes of a
demonstration), the system should be decontaminated (purged with an inert
gas) before powering down the analyzer.
Cleaning and decontaminating the analyzer for shipment or
storage:
1. Shut off the process gas flow.
2. Allow all residual gas to dissipate from the lines.
3. Connect a purge supply (N
2
), regulated to the specified sample
supply pressure, to the sample supply port.
4. Confirm that any valves controlling the sample flow effluent to the
low pressure flare or atmospheric vent are open.
5. Turn on the purge supply and purge the system to clear any residual
process gases. For differential systems, make sure to purge the
scrubber/dryer for several dry cycles. If necessary, dry cycles can be
initiated by pressing the # key followed by the 2 key to enter Mode
2 and then pressing the # key followed by the 1 key to return to
Mode 1.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
of the sample and prescribed safety precautions before installing,
operating or maintaining the analyzer.
