SECTION 3

STARTUP AND OPERATION

3-1 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 assumed operational.

3-2 STARTUP PROCEDURE

WARNING

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 enclosure 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."
