6. Configuration
This chapter provides details of all the setting items and shows the locations of the setting menus
of the TDLS8000. However, the setting items related to calibration and validation are described in
“9. Inspection and Maintenance”.
The setting menus of the YH8000 can be opened by performing the operation of “ >> Select
analyzer >>Configuration” but the location is shown as just being under “Configuration” in this
chapter for simplicity.
6.1 Process Parameter Settings
Process parameters indicate the measurement conditions related to measurement process gas.
Set the process optical path length, process pressure, and process temperature of the process
gas correctly because they directly affect the measurement values.
NOTE
If nitrogen purge gas will not be used, you also need to configure the non-measurement process
optical path length, pressure, and temperature in addition to the settings in this section. For
details, see “6.10 Non-process Parameter Settings”.
6.1.1 Process Optical Path Length
Set the process optical path length of the process to be measured. For a definition of the process
optical path length, see “5.3.2 Setting the Process Optical Path Length”.
Setup menu path:
[HART] “Detailed setup>>Analysis>>Process param>>OPL”
[YH8000] “Configuration>>Analysis>>Process Parameters>>Path Length”
6.1.2 Process Pressure
Set the process pressure of the process to be measured. When you select the input source, set
the action for error input as described in the procedure below.
Setup menu path:
[HART] “Detailed setup>>Analysis>>Process param>>Pressure”
[YH8000] “Configuration>>Analysis>>Process Parameters>>Pressure”
(1) Select “Mode” (pressure input mode).
When “Fixed” is selected, set the pressure value as an arbitrary fixed value.
When “Active input” is selected, input the pressure value via a 4-20 mA analog input (AI-1)
or Modbus. The TDLS8000 acquires a pressure value sent from the input source at every
measurement value analysis cycle and uses it for the concentration calculation.
(2) Configure the settings below according to the pressure input mode.
When “Fixed” is selected
Enter a fixed pressure value for “Fixed mode value.” The other parameters do not need to
be set.
When “Active input” is selected
Set each of the following parameters.
• Active type: Setting of pressure input source
“AI-1” is analog input (AI-1).
