ABB PGC2000 Operation And Service Manual page 50

It is the customer's responsibility to ensure that the hydrogen supply to the
analyzer does not exceed 100 psig (689 kPa, 6.89 bar) and that the customer's
pressure relieving devices are set to relieve at 200 psig (1380 kPa, 13.8 bar).
Failure to control the hydrogen pressure within these specifications may cause
loss of property and loss of life.
5. Turn ON Burner Fuel and Burner Air at the flow shut off valves and observe the Actual values
shown on the Manual Pressure Control Mode screen. Ensure pressures are set according to the
Data Package and adjust set points (SP) as necessary. If the analyzer has mechanical
regulators, observe the gauges on the Pressure Control Panel and adjust the regulators as
necessary.
6. After the temperature stabilizes, recheck all purge air pressures at the gauges on the Purge Air
Panel. Adjust corresponding regulators, if needed, according to the Data Package.
7. Check column pressure by examining the Actual values for Carrier #1 and Carrier #2 shown on
the Manual Pressure Control Mode screen. Verify these values with the Data Package
specification and adjust the Carrier #1 and Carrier #2 set points as necessary.
8. If the analyzer has mechanical regulators, check column pressure by examining the Carrier #1
and Carrier #2 gauges on the Pressure Control Panel and verify these values with Data Package
specifications. Adjust the Carrier #1 and Carrier #2 regulators as necessary.
9. Turn ON Calibration Gas supply (may be called Standard Sample). The gauges and regulators
used to monitor the calibration gas are normally part of the Sample Conditioning System. If
necessary, adjust the appropriate controls on the Sample Conditioning System to provide the
analyzer with correct sample pressure and flow, according to the Data Package.
10. On the Background screen press the F2 (Manual Control) soft key.
11. On the Manual Control Mode screen press the F2 (Detector and Graphics) soft key.
12. For an analyzer with a TCD:
a. On the Chroma Board screen press the F3 (Manually Zero Baseline) soft key.
b. Add the values of the Hardware Zero reading and Software Zero reading.
c. Open the GCC front panel and locate the TCD Amplifier Board on the left side wall of the
GCC.
d. Adjust the TCD Zero Adjust on the TCD Amplifier Board until the Detector Reading on the
Chroma Board screen is equal to the sum of the Hardware and Software Zero readings.
e. On the Chroma Board screen, press the F3 (Manually Zero Baseline) soft key. The Detector
Reading should now be 2.00 ± 0.05 mV and the Hardware Zero should be 10% or less.
f. Close and fasten the GCC front panel.
