Decimal Alarm
Bit Value Type Alarm Condition / Description and Suggested Corrective Action
4 16 Warning w: Zero gas pressure range
The Zero gas pressure is outside of 1 % to 99 % of full-scale range.
Note: This alarm is used only by analyzers with the pressure transducer
option.
Corrective Action:
•
Check the Zero gas regulator on the Zero gas bottle and ensure it has an
adequate supply.
• Check the Zero gas pressure gauge and ensure that it is at an appropriate
pressure (see “Zero Gas” in Chapter 3). Adjust the pressure regulator until the
pressure is at an appropriate level. The pressure must be less than the 1380
kPag (200 psig) maximum Cell Pressure.
• From the Analog Inputs dialog box, check the Cell Pressure Low and High
range readings. If the High range reading is > 100 PSIA (5171.5 mmHg) or the
Low
range reading is < 66 PSIA (3413.2 mmHg), this indicates the pressure
transducer is saturated; it won’t allow the analyzer to perform an Auto-Zero.
Adjust the pressure to 80 PSIG and restart the Auto-Zero.
Take appropriate safety precautions, open the Lower Enclosure, and:
• Check the pressure transducer.
•
Check the zero solenoid.
•
From the Output Setup dialog box, confirm the
Low Scale
and
High Scale
pressure settings are correct.
• Confirm the Measuring Cell pressure transducer jumpers on the
Customer I/O
board are configured correctly (see “Compensations” in Chapter 4).
•
Replace the Customer I/O board. Contact AMETEK to verify operation
before removing this board.
5 32 Warning w: Sample gas pressure too high
The sample gas pressure is above 99 % of the full-scale range.
Note: This alarm is used only by analyzers equipped with the optional
pressure transducer.
Corrective Action:
•
Check the sample gas pressure gauge and ensure it is at an appropriate flow
and pressure (80 PSIG), or as recommended on the system drawings.
•
From the Output Setup dialog box, confirm the sample gas
Low Scale
and
High Scale pressure settings are correct.
Take appropriate safety precautions, open the Lower Enclosure, and:
•
Check the pressure transducer.
•
Confirm that the pressure transducer jumpers on the Customer I/O board are
configured correctly. See “Cell/Miscellaneous (Compensation) Parameters” in
Chapter 4.
