P3
Heated Flame Ionization Detector Analyzre Module
Rosemount Analytical NGA 2000
PREFACE
CAUTION: PURGE AIR REQUIREMENT
This Analyzer Module must be used in conjunction with a device (Control
Module or PC Interface) that can actively monitor network variables related to
pressure or flow of the continuous dilution purge, or the front panel LEDs of the
Analyzer Module, as installed, must be visible. The purpose of this requirement
is to maintain adherence to ANSI/NFPA 496 standard which assures the
continued viability of the purge system. Under no circumstances should any
pressure or flow indicator be connected to the PURGE AIR OUT outlet of the
Analyzer Module because this may affect the sealing performance of the
module.
CAUTION: PRESSURIZED GAS
This module requires calibration with a known standard gas. See General
Precautions for Handling and Storing High Pressure Gas Cylinders at the rear of
this manual.
WARNING: POSSIBLE EXPLOSION HAZARD
Ensure that all gas connections are made as labeled and are leak free. Improper
gas connections could result in explosion or death.
CAUTION: OVER-VOLTAGE SPIKING
If this Analyzer Module is used with a non-Rosemount Analytical power supply,
adding Rosemount P/N 903341 Current Protector in series with the 24 V positive
power line will prevent over-voltage spiking and resultant fuse blowing when
powering up the instrument.
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:
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 (six) minutes at the
minimum pressure of 689 hPa (10 psig).
