220 AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B
1 analyzer module, external gas supply with 1 solenoid valve
To calibrate analyzer modules with simplified calibration 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.
The external solenoid is controlled via a digital output on the electronics
module (Digital output DO4 on Digital I/O module – "Status signals/ Exter-
nally controlled calibration" (see page 112) standard function block applica-
tion).
1 analyzer module, external gas supply with 3 solenoid valves
To calibrate all analyzer modules with zero and span gas, even without an
integral pneumatic module.
The external solenoid valves are controlled via digital outputs on the elec-
tronics module (Digital outputs DO1, DO2 and DO3 on Digital I/O module –
"Calibration control" (see page 112) standard function block application).
