3-4 STARTUP & INITIALIZATION
1. Check the sample system operation, and
make sure that flows are correct. Be
careful not to destroy the Analyzer flow
sensor with excessive flow (maximum 2
l/min).
NOTE
Ensure that all flow and pressure
settings are at or below their rec-
ommended values before applying
gas or power to the Analyzer mod-
ules. Instrument damage can occur
if maximum values are exceeded.
2. Check the power connections, and LON
connections, and power up the system.
Do not initiate any PC LON software yet.
3. The Platform should interrogate the sys-
tem, and build its database. See the NGA
2000 Reference manual for troubleshoot-
ing information if anything goes wrong.
4. Apply power to the NGA 2000 Platform by
plugging it into a power source. The Plat-
form has no ON/OFF power button. Once
power has been supplied to the Platform,
any connected Analyzer modules will be
energized.
5. After switching on the CLD, the Analyzer
will begin its booting procedure which is
apparent on the LCD screen. The first
part of the initialization procedure is a self
check of the software and Analyzer com-
ponents. Various displays will show the
status of the initialization including revi-
sion notes.
6. 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 se-
quence will interrogate the network to lo-
cate and identify all components on the
network. The user will have to bind ap-
propriate combinations of components
after the startup sequence. See Section
2-6 for instructions on binding combina-
tions of modules.

7. Pressing the F1 key during initializing will
reset the LCD brightness and contrast to
factory settings (See Section 3-6c).
Pressing the F3 key will abort the network
initializing, aborting any connection to
other Analyzers. In that case, only the
menus of the local Analyzer will be avail-
able.
8. At the end of the initializing routine the
“measure” screen will display. This screen
is the access to all other channels, menus
and submenus. The actual display may
differ from that shown depending on any
custom configuration as described in
Section 3-5.
9. Check that the Platform has found all the
Analyzer modules and I/O modules, and
all have been correctly bound. Systems
are normally provided already setup, but if
not done, bind the I/O modules to the
Analyzer modules using the procedure
outlined in the NGA 2000 Reference
manual.
10. Set up any PC interface components.
11. Verify the operation of the Analyzer mod-
ules on zero and span gases, and then on
the sample itself.
12. Verify the Analyzer module linearity on
mid-scale span gases.
13. Verify the operation of the sample system.
14. After the warm-up period (about one hour
for most Analyzer modules), all modules
are completely functional.
