Yokogawa In-Situ Gas Analyzer TDLS200 - Manual (Page 13)

<2 QUICK START> 2-3
9.0 Confi gure
ADVANCED Using the correct password (Default 1234), enter in to the Advanced Menu, then the Confi gure.
9.1 Select the desired measurement units (English or Metric selected on an individual parameter basis).
9.2 Optical Path Enter in the correct optical path length.
9.3 Gas Pressure Select Fixed or Active.
If Fixed, enter in the correct process gas pressure.
If Active, enter in the 4-20mA input signal range proportional to the pressure range.
“Control” mode is not applicable to TDLS200
9.4 Gas Temperature Select Fixed or Active.
If Fixed, enter in the correct process gas temperature.
If Active, enter in the 4-20mA input signal range proportional to the temperature range.
Active ambient and Active Peaks may also be used, refer to project specifi c and application
specifi c details.
“Control” mode is not applicable to TDLS200
9.5 Confi gure the system I/O by entering in to the System I/O sub menu in Confi gure.
9.6 If the Analog I/O board is installed, then select Analog Output and set the appropriate 4mA and
20mA values for Ch1 Concentration and Ch2 Transmission.
9.7 Select what mode (Block, Track or Hold) the 4-20mA outputs are to be when the analyzer is in
Warning, Fault and Calibration Modes.
9.8 Confi gure Digital outputs – Warnings and Faults. Many of these will be factory preset so if unsure
about any settings then leave as Factory Default. Select and set level for Alarm Limit to either the
Measured Gas orTransmission.
9.9 Go to the Data screen and set the appropriate parameters for and ‘Spectrum Capture’. These will
ensure the analyzer stores important information during operation that may be used to verify
operation/status/diagnostics and other trouble shooting.
9.10 Go to the Trends screen and review/plot several of the listed parameters to check analyzer
performance over a period of time.
9.11 Non- Process
Parameters If the application use gas containing the target gas (e.g. Oxygen measurement with
Instrument Air Purge) then the Non-Process parameters should be confi gured as detailed later in
this manual under the Software Section. Non-Process Parameters should also be confi gured if
using a linelocking gas in the validation cell (e.g. CO for combustion).
10.0 Normal Operation When the site/fi eld confi guration is complete and the analyzer has operated for at least two hours
without any functional alarms, then perform an export data routine.
10.1 To Export Data, simply insert an empty USB memory stick in to a USB port on the launch unit back
plane. The data transfer may take several minutes.
DO NOT REMOVE THE MEMORY STICK DURING THIS TIME!
10.2 Close out the VNC software and disconnect the service PC – if connected.
10.3 Ensure the doors/lids are closed and tightly sealed.
10.4 The system is now in normal operation mode.
10.5 We RECOMMEND sending all the Exported Data fi les to Yokogawa Laser Analysis Division
along with any notes and comments. We will then be able to store these fi les on a master
record for future reference.
Please carefully read the appropriate Sections of this Instruction Manual. The TDLS200 Tunable Diode
Laser (TDL) Analyzer is a technologically advanced instrument that requires the appropriate care when
handling, installing and operating.
Failure to do so may result in damage and can void any warranties!
If there is any doubt about any aspect of the Instrument or its use, please contact Yokogawa Laser
Analysis Division and/or your authorized Representative/Distributor.
