Page 16: Overview
<1. Overview> Overview Yokogawa’s TDLS 8200 is a laser gas analyzer that measures the concentration of gases (O CO, CH NH3, HCl) in various processes such as petrochemical, power generation. Since it can be inserted directly into the duct, the sampling equipment is unnecessary and installation cost and maintenance cost can be reduced.

Page 41: Installation Conditions
Install the product in a location that meets the conditions indicated in “1.3 Specifications”. Note the following points. • Process window purge protects the TDLS8200 from the heat, dust, and corrosive elements of the process gas. Be sure to run the process window purge gas during processing. The process window purge gas flow rate varies depending on the process gas conditions.
Page 42: Process Gas Temperature
Process flow rate Install TDLS8200 at a location with a flow rate of 1 m/s or above. Flow rate of 5 m/sec. or above secures more stable measurement. Install TDLS8200 at a location with minimum fluctuation of flow rate, otherwise it may result in the deviation of the measurement result.

Page 56: Connecting The Power Cable And Grounding
CAUTION Connect the power supply wires to the correct locations and don’t reverse polarity. Incorrectly connecting “PWR” the power supply can cause the TDLS8200 to malfunction. Use two-core or three-core shielded cable to wire the power supply. For ground wiring, use the internal ground terminal or external ground terminal. If you want to use the internal ground terminal, use a three-core power cable.
Page 57: Connecting To Temperature And Pressure Transmitters
For analog input settings, see “4.3 Analog Input Settings”. Connection Preparation To supply power to the transmitters from the TDLS8200, set the switch inside the analyzer part to Active AI. To supply power externally, set to Passive AI. If you want to connect to a 4-wire system pressure meter or thermometer, set to Passive AI.
Page 58 • For the cable type to use, see page 2-16 “n Types of Wiring and Cabling”. • Be sure to ground the cable shield on the TDLS8200 side and on the other side. • When supplying power to the transmitters from the TDLS8200, take into account the drop in the transmitter supply voltage due to wiring resistance and the like.
Page 59: Wiring Analog Outputs (Ao)
• For the cable type to use, see page 2-16 “n Types of Wiring and Cabling”. • Be sure to ground the cable shield on the TDLS8200 side. • For each output, keep the load resistance including the wiring resistance 550 Ω or less.
Page 60: Wiring Digital Outputs
• For the cable type to use, see page 2-16 “n Types of Wiring and Cabling” • Be sure to ground the cable shield on the TDLS8200 side and on the other side. • The contact rating is 24 V DC 1 A. Connect a load (e.g., indicator lamp, annunciator) that will not cause these values to be exceeded.
Page 61: Wiring Digital Inputs
• For the cable type to use, see page 2-16 “n Types of Wiring and Cabling”. • Be sure to ground the cable shield on the TDLS8200 side and on the other side. • The open and closed levels of the digital inputs are identified by the resistance seen from the TDLS8200 side.
Page 62: Wiring Solenoid Valve Control Outputs
• For the cable type to use, page 2-16 “n Types of Wiring and Cabling”. • Be sure to ground the cable shield on the TDLS8200 side and on the other side. CAUTION • The output rating is +24 V DC 500 mA max. Check that the solenoid valves that you want to use do not exceed these values before connecting them.
Page 63: Connecting An Ethernet Cable
When connecting the TDLS8200 to a network, manage the network appropriately. If you want to connect the TDLS8200 to an YH8000 (HMI unit) through an Ethernet hub or to an external device through Modbus/TCP communication, you will need to use an Ethernet cable.
Page 64 Finally, check that the plug has been crimped on properly by testing the connection with a LAN cable tester. (5) Insert the RJ45 connector into the TDLS8200 Ethernet port and the round crimp-on terminal at the end of the shielded wire to the functional ground terminal (M4 screw) inside.
Page 65: Optical Axis Adjustment
When wiring is complete, turn on the power, and adjust the optical axis as necessary. CAUTION The TDLS8200 is a Class 1 laser product. As such, the laser level of the product is safe to the eyes, but do not intentionally look at the laser light source. The TDLS8200 laser unit emits laser beam from the analyzer part as soon as the power is turned on.
Page 66 <2. Installation, Wiring, Optical Axis Adjustment, and Piping> n Optical Axis Adjustment As shown in Figure 2.20, there are some optical axis adjustment knobs on TDLS8200. Their position varies depending on the specification of each equipment. Unused knobs are sealed with stickers.

<4. Configuration> Configuration This chapter provides details of all the setting items and shows the locations of the setting menus of the TDLS8200. However, the setting items related to calibration and validation are described in “6. Inspection and Maintenance”. Process Parameter Settings Process parameters indicate the measurement conditions related to measurement process gas.
Page 93 If the analog input immediately after turning on the power of the TDLS8200 is out of range while “Hold” is selected, a pressure value corresponding to 4 mA is held.
Page 94 • If you select “Disable” in the backup mode, the last pressure value you enter remains valid i.e. in the same status as “Hold”. • After the power of TDLS8200 turns on, the backup function keeps active until the first pressure value is received. During this period, when you select “Hold”, or “Disable” in the backup mode, the pressure values will be on hold at the equivalent of the one obtained within the Analog input range mentioned below (3) with 4mA.
Page 95: Process Temperature
When “Active input” is selected, input the temperature value via a 4-20 mA analog input (AI- 2) or Modbus. The TDLS8200 acquires a temperature value sent from the input source at every measurement value analysis cycle and uses it for the concentration calculation.

This section describes the handling precautions to be taken when installing and operating the TDLS8200 in order to maintain the level of safety designed for using the TDLS8200 in a Safety Instrumented System application. It also provides an overview of the operation. The topics discussed in this section are the TDLS8200’s proof test, repairs, and replacement;...
Page 209: Connecting External Transmitters
App.4-2 <Appendix 4 Safety Instrumented System Installation> l Opening and Closing the TDLS8200 When online, do not open or close the cover. If you need to open and close the TDLS8200 cover for maintenance, obtain permission from your safety administrator. l Configuration Use the HART Configuration tool or a YH8000 HMI unit to set the range and unit. Connect the HART Configuration tool or the YH8000 according to the instructions in this manual.
Page 210: Proof Test
If a fault is detected, please consult with Yokogawa. The operator that performs proof tests on the TDLS8200 must have a thorough knowledge of the operation of Safety Instrumented Systems, including the bypass procedure, TDLS8200 maintenance, and change procedures.
Page 211: Firmware Updating
The expected useful lifetime of the TDLS8200 is 10 years. The reliability data in the FMEDA report is valid to 10 years. It is assumed that the failure rates of the TDLS8200 would increase when it is used over 10 years. Therefore, the safety integrity level based on the reliability data given in the FMEDA report may not be attainable.
Page 212: Terminology And Acronyms
When restoring zero or span calibration data to “factory default data”, an error may occur. It is possible to restore the data by performing the operation again. If the error occurs repeatedly, please contact Yokogawa service representative. For details about the operation, see “6.7 Calibration Data Record and Restoring”.
