Immediately notify the shipping carrier if the carton or its contents are damaged. Retain the carton and packing material until the instrument is operational. ASSEMBLY If the Analyzer Module requires assembly with other components, do so at this time.
Instruction Manual 748297-E June 2003 Model NGA2000 HFID tal. Otherwise, water may accumulate in the line, causing back pressure and noisy readings, or may back up in the line and flood the burner. Depending on the percent of water vapor in the sample, the sample bypass out connection may have condensation. Proper drainage may be required. All new external gas tubing (except for PURGE IN/OUT and SAMPLE BYPASS) is strongly recommended, preferably precleaned, stainless steel, gas chromatograph-grade tubing.

Instruction Manual 748297-E June 2003 Model NGA2000 HFID 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. 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.
Instruction Manual 748297-E June 2003 Model NGA2000 HFID • EPROM test - Checks the EPROM on the Analysis Computer PCB. • RAM test - Checks the RAM on the Analysis Computer PCB. • Power supply test - Verifies that all internal DC voltages are within the required tolerances. • Network test - Checks the internal network interface. • 20 bit ADC test - Checks the 20-bit ADC on the Analysis Computer PCB by sending a DC signal through the Preamp PCB and reading the signal back with the 20-bit ADC.
Instruction Manual 748297-E June 2003 Model NGA2000 HFID Noncompliance could cause damage to the module. At the very least, the module's safety system, which requires a certain volume of purge air flowing through the case before allowing burner ignition, will not allow the instrument to operate. The lowest purge air flow/pressure setting possible during burner operation is preferable. Thus, the user should set the external purge air pressure initially at 689 hPa-gauge (10 psig).
Instruction Manual 748297-E June 2003 Model NGA2000 HFID 15. Check and re-adjust the internal pressures if required. 16. The unit is ready for operation. 3-3 3-4 BINDING To achieve full coordination between Analyzer Modules and associated I/O Modules, the user must bind those components together in the System Set Up portion of the Technical Configuration Menu in software. CALIBRATION Calibration gas setup is as follows: 3.
Instruction Manual Model NGA2000 HFID If the user is unable to calibrate the Analyzer Module (i.e., when ZERO or SPAN is initiated, nothing happens), several possible solutions present themselves. One solution relates to the use of an incorrect gas for zeroing or spanning (e.g., using a high concentration gas to zero or a zero gas to span the Analyzer Module).
Instruction Manual 748297-E June 2003 3-6 SAFETY SYSTEM The HFID Analyzer Module safety system will not allow ignition or continuous burner function unless the following conditions are present: • • 3-6 Model NGA2000 HFID The internal purge gas pressure is at least 380 hPa - gauge (5.5 psig). (Monitor display message, Purge Gas Pressure in Physical Measurements menu, for proper setting.) Flow rate for purge air in is at least 16 L/min. and case pressure is greater than 0.5 inches of water.
