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 enclosure:
Non-Classified.
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 minutes.
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 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 sequence will interrogate
