OVERVIEW

Prior to initial startup, the user should leak test
the module as outlined in Section 2.
For the remainder of this section, Analyzer
Module interconnection with a control module
or some interfacing component will be as-
sumed operational.

STARTUP PROCEDURE

PRESSURIZED ENCLOSURE
This enclosure shall not be opened unless
the area is known to be free of flammable
materials or unless all devices within have
been de-energized.
Area classification for the protected enclo-
sure:
Nonclassified.
Pressurization: Type Z
Temperature Identification Number: T4A
Power shall not be restored after enclo-
sure has been opened (or loss of purge)
until enclosure has been purged for a
minimum of 6 minutes at the minimum
pressure of 689 hPa (10 psig). For safety,
the Analyzer Module should be installed in
a non-confined, ventilated space. Do not
block any of the rear panel outlets as they
are part of the safety system.
1. Connect supply gases and outlets
to/from module.
2. Turn ON the purge gas only. Perform a
leak check. Wait a minimum of 6 min-
utes.

3. Connect the LON cable(s) and the
+24VDC power cable.
4. Turn power ON.
5. Check the 4 LEDs. The power green
LED should be illuminated. The Oven
amber LED should be blinking or on.
The other LEDs should be OFF.
6. Allow the network to initialize.
If the user's system contains only one
Analyzer Module, all system compo-
nents, the Controller Board and the net-
work "self-install" (bind together) during
initial startup. If the system contains
more than one Analyzer Module, the
startup sequence will interrogate the
network to locate and identify all com-
ponents on the network. The user will
have to bind appropriate combinations
of components after the startup se-
quence. (See Section 3-3 on page 3-4.)
7. Check the general health of the analyzer
by reviewing the status of the Self Tests.
All "Pass" conditions should be ob-
tained.
These test results can be found by se-
lecting the following from the Main
Menu: Technical Level Configuration,
Diagnostic Menus, Analyzer Module Di-
agnostics, Self Test. All tested parame-
ters should indicate "Pass."
