Initialization
6.2.2
Normal Mode
OMA-2000 analyzer performs the measurement tasks and may stay in normal or alert status.
z
Normal Status:
OMA-2000 analyzer performs the measurement tasks normally and the
analog input port (4-20)mA outputs the measurement value of the corresponding gas density.
The density of measured gas will be displayed on the LCD of operation panel.
z
Alert Status:
The system will alert when the measured density or pressure is abnormal, or
the gas path has been blocked. In the meantime, the LCD of the operation panel will display
the density of measured gas and the bottom of the LCD will light up the alert status like
“System Alert” or “Abnormal Pressure”.
Note:
: Used to indicate the normal status;
：
Used to indicate the alert status which requires the checking of such information.
Please refer to
7.1 Alert Information
.
6.2.3
Failure Mode
The system will automatically switch itself to failure mode when the temperature control is
abnormal. Under this mode, the system will stop the measurement of gas density and display the
density of last normal measurement. Now the “Temperature Error” at the bottom of the LCD will
be lighted up to alert status.
