Operation
3.1 Overview
The 943-TGS-CE analyzer system is designed to operate automatically with a minimum need
for human intervention. Once installation, commissioning and initial start-up have been
completed, the only human intervention required is when the system indicates a problem or
when routine preventative maintenance is scheduled. Section 4 of this manual describes the
local user interface (UI) displayed on the analyzer’s full-colour display and its operation using
the handheld keypad.
The analyzer system computer automatically performs all the normal operational procedures
including sample flow initiation, sampling and analysis, back purge and zero calibration , range
sensitivity selection, fault detection, temperature zone control, and fail-safe back purge in the
event of an analyzer fault. Operators are alerted to an abnormal state or fault occurrence
through indicators on the local display located on the control cabinet door as well as fault and
warning relay contact closures.
The only manual adjustments to system controls (not through the computer) are the flow control
of various instrument air streams. Flow adjustment valves for the zero/purge gas flow rate, the
aspirator drive air flow rate and the probe cooler (used for sulfur vapour condensation at the
probe tip) air flow rate are located on the left side of the oven cabinet
All valves are clearly labeled according to their title and function. The Flow Diagram drawing
shown in Figure 15 provides a schematic of the flow streams in the analyzer sample handling
system.
