<6. Configuration>
6-3
IM 11Y01D01-01EN
When “Active ambient” is selected, the value of the temperature sensor mounted in the
vicinity of the laser device in the TDLS8000 is used as the process temperature.
(2) Configure each of the settings below according to the temperature input mode.
When “Fixed” is selected
Enter a fixed temperature value for “Fixed mode value.” The other parameters do not need
to be set.
When “Active input” is selected
The setting items are the same as those in section 6.1.2. Read “pressure” as “temperature”
and “AI-1” as “AI-2” when configuring the settings.
When “Active ambient” is selected
Set the temperature offset value in “Temp act amb ofst” (“Offset value” on the YH8000).
The temperature sensor value is the temperature in the vicinity of the laser device, and is
not exactly equal to the process temperature so set a difference as an offset.
(3) Configure the analog input range setting only when “AI-2” is selected in “Active type.”
Enter the temperature value corresponding to each of 4 mA and 20 mA.
Setup menu path:
[HART] “Detailed setup>>I/O condition>>Analog input>>AI-2(Temperature)”
[YH8000] “Configuration>>I/O>>Analog Input>>AI-2 (Temperature)”
6.2 Unit Settings
Set the units for physical quantities related to concentration measurement. The physical
quantities for which units can be set are “optical path length,” “pressure,” and “temperature,” and
you can select from the following units for each of them.
When Only SI unit (-J) is assigned to TDLS8000, non SI Unit will not be displayed.
Item SI
Optical path length m, cm inch, feet
Pressure kPa, atm, bar psi, torr
Temperature deg C, K deg F
Setup menu path:
[HART] “Detailed setup>>Analysis>>Unit”
[YH8000] “Configuration>>Analysis>>Units”
6.3 Analog Input Settings
Analog input is used for the purpose of calculating a pressure value and temperature value from
analog input within the 4-20 mA range. Set the pressure value and temperature value ranges
here which will correspond to 4 mA and 20 mA.
Setup menu path to A1-1 (pressure input):
[HART] “Detailed setup>>I/O condition>>Analog input>>AI-1(Pressure)”
[YH8000] “Configuration>>I/O>>Analog Input>>AI-1(Pressure)”
Setup menu path to A1-2 (temperature input):
[HART] “Detailed setup>>I/O condition>>Analog input>>AI-2(Temperature)”
[YH8000] “Configuration>>I/O>>Analog Input>>AI-2(Temperature)”
