Test Gas Supply Control For Automatic Calibration - ABB AO2000 Series Operating Instructions Manual

Test gas supply control for automatic calibration

Test gas supply
1 analyzer module, integral pneumatic module with 1 solenoid valve
1 analyzer module, integral pneumatic module with 3 solenoid valves
AO2000 CONTINUOUS GAS ANALYZERS
The test gas supply for automatic calibration can be started by means of the
gas module's integral solenoid valves or via external solenoid valves.
Depending on the gas supply circuit and the number of analyzer modules
installed there are several layout possibilities for the test gas supply:
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.
•
To calibrate all analyzer modules that can be used with the pneumatic mod-
ule.
