SYSTEM SETUP

The usual NGA system consists of a control
module, one or more analyzer modules, and
one or more I/O modules. If you have only the
one analyzer module, the system will set itself
up automatically, but if you have more than one
you will have to give it some instructions as to
how to configure itself. In particular, you have
to tell it which analyzers are connected to which
I/O modules.
If you have no I/O modules,. you can skip this
section.
If you have more than one control module in a
system, whether or not you have more than one
display in it, you will need to read the advanced
section here.

Basic Instructions

Verify you have all the modules you are go-
ing to use, and that they are all connected
to the power supplies, and to the LON.
Power connections are normally made
through the three pin connector on the front
of each analyzer module, or through the
audio connector on the back of the plat-
forms. You can power a single analyzer
from the internal power supply in a platform,
but if you have more than one analyzer you
will need some sort of additional power
supply, such as the 24V, 30 amp Bulk
Power Supply made by Rosemount Analyti-
cal. Each analyzer draws about 5 amps, so
a 30 amp supply can handle about five ana-
lyzers.
IMPROPER CONNECTION
The internal LON connection in the platform
is for use with internally mounted and pow-
ered analyzers only. Using this connection
for external analyzers or LON components
could result in short-circuiting the 24V
power supply through the cable, with resul-
tant damage.

Binding

You have to tell the system which I/O mod-
ule is bound to which analyzer.
Version 2.2 control modules:
Verify that all the analyzers and I/O mod-
ules are present:
Enter the Main menu.
Enter Technical level configuration...
Enter Listing of all modules...
Verify they are all there. (Note that system
Autocal modules are listed as five separate
modules.)
Enter the Main menu (press "HOME" or
"MENUS")
Select Technical level configuration...
Select System setup..
Select Module binding...
Verify that the analyzer listed on the Ana-
lyzer module selected: line is the correct
one.
If it isn't, select View bindings.... press
"NEXT" until the desired analyzer is shown
on the Analyzer module selected: line.
Press the left arrow key to return to the
Module binding menu
Select the desired module. You will jump
back to the previous menu.
Check that the I/O module selected is cor-
rect for the analyzer shown - NOT the ana-
lyzer at the very top of the screen!
Press "BIND".
Wait while the system restarts, and then re-
enter the binding menu.
Repeat the procedure for each I/O module
until all are bound.
