AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B 221
3 analyzer modules, external gas supply with 1 solenoid valve
To calibrate three analyzer modules connected in series with simplified cali-
bration procedures:
• Caldos27 with single-point calibration
• Magnos206 and Magnos28 with single-point calibration
• Limas11 IR, Limas21 UV, Limas21 HW with calibration cells
• Uras26 with calibration cells
• Oxygen sensor.
During the calibration of the analyzer module the external solenoid valve is
as standard controlled via a digital output on the electronics module via a
digital output (Digital output DO4 on Digital I/O module – "Status signals/
Externally controlled calibration" (see page 112) standard function block
application).
If the sample components of the individual analyzer modules show cross
sensitivities among each other, it must be made sure by appropriate ar-
rangement of additional solenoid valves that the test gas can be supplied
separately to each analyzer module. When activating the solenoid valves, it
must be taken into consideration that all analyzer modules are calibrated
simultaneously during automatic calibration.
