It is normal for a Platform to run out of
memory if it is given too many Analyzer
modules to deal with, or Analyzer mod-
ules are replaced too often without reset-
ting it. V2.2 Platforms can deal with about
6 Analyzer modules, and V2.3 or later
with about 10 (when used with the in-
creased RAM Platform Controller board).
The symptom of this is that the Platform
hangs up while starting up, or continu-
ously restarts itself. In this case, you need
a hardware upgrade, and should call
Rosemount Service.
3-6 BASIC CONTROLS, SETUP AND STATUS
The following sections describe the basic
control of the NGA 2000 Platform and any in-
stalled Analyzers. Examples of stepping
through the menus are shown so that the user
can become familiar with the operation,
keeping in mind that displays and menu
choices may be different depending on the
configuration and any customization of the
menus.
NOTE
See individual Analyzer manuals for
more detail and module specifics.
