Emerson Process Management CFA-3000 User Manual

Accuracy: All two­decade ranges up to 1000 ppb
maximum: ±10% of reading or ±2 ppb, whichever is
greater

0.1­10 ppm range = ±10% of reading or ±0.5 ppm,
whichever is greater

Automatic Calibration: 40 minutes

Total Calibration: 40 minutes, twice/week

Reagent Consumption: 5 L of each reagent per 3
months

Standard Consumption: 1 L of high standard,1 L of
low standard per 3 months

Flow: 40­50 mL/min
Current standard bottles are:

“0”­(baseline): 1.0 L.
Full­scale: 5.0 L

Pressure: <10 psig (<170 kPa)  (overflow cup must
drain to atmosphere)

Temperature: 0­50° C (32­122° F)

Filter: 8 micron filter in sample line is
Recommended; (#180­1341­08).

Multiple Stream Option: General: up to 6 sample
streams; measurement is sequential

Response Time:  15 minutes (method­dependent)

Outputs: 4­20 mA or 0­5 Vdc (non­isolated). 
(Isolated output is optional.)

Load requirements for 4­20 mA output: 450 ohms
minimum, 1200 ohms?  maximum

Load requirements for 0­5 Vdc output: 10 k Ohms,
minimum

The range of outputs is the same as the measure­
ment range. Parallel output for printer is optional for

single stream, standard for multi­stream monitors.
RS232C output is optional for single stream monitors,
standard for multi­stream monitors.

General:   contact closures for
•   leak detection,
•   calibration in progress,

Contact closures are rated:2 A at 250 Vac or 3 A

at 30 Vdc; delay on/off is 1 minute

•   One alarm relay for each stream; contacts have  

dc ratings

•   100 Vdc (maximum ­ carry only)
•   0.5 A (maximum ­ switched) 
•   delay on/off time is 1 minute

Display: Single line LCD, 4 1/2 digits, readout in
concentration units. For multi­stream option display
remains at last value until new stream reading is stable.

•   Leak,
•   Lamp failure, 
•   Quarterly maintenance due
•   Calibration in progress.

For multi­stream analyzers.

•   the sample stream currently selected 
•   the sample stream for which data is being

displayed.

Environmental: The analyzer is not intended for out­
door use. Install in a clean, indoor environment.

Ambient Temperature:
40­120° F (10­45° C)  must be regulated to ± 10°
within 

range, avoid temperature swings 

greater than ± 10° F (± 5± C) over a 12­hour period

Humidity: 5­95% (non­condensing)
Pollution degree: Standard
Altitude: Not applicable
