The Help structure is on-line "tutorial," context-sensitive and topic-interconnected, so
that the user can practically operate NGA 2000 without need of an instruction manual.
3.3 STARTUP PROCEDURE
Introduce zero gas into SAMPLE INLET and reference and source purge gas, if
applicable, into their respective inlets. Ensure that gas pressures are set to
requirements listed on the Specifications page of the Preface section of this manual.
Apply power to the NDIR Analyzer Module. If it is associated with a Platform, do this
by plugging in the Platform to a power source. The Platform has no ON/OFF power
switch. Once power has been supplied to the Platform, the NDIR Analyzer Module will
be energized.
If the user's system contains only one Analyzer Module, all system components, the
Controller Board and the network "self-install" (bind together) during initial startup. If
the system contains more than one Analyzer Module, the startup procedure will
interrogate the network to locate and identify all components on the network. The
user will have to bind appropriate combinations of components after the startup
sequence.
After the warm-up period (about one hour for the NDIR Analyzer Module), all modules
are completely functional.
Check the tune and detector signal values against the factory settings listed in the
Diagnostic Service menus. If both settings are within
±
5% tolerance of factory setting,
go to section 3.4 for binding and 3.5 for calibration. If not, refer first to section 4.11 for
instructions about oscillator tune/source balance shutter adjustments
