Detector: GD40G (General Purpose), GD40R (TIIS) (Style S2), GD40T (FM), GD40V (CSA) (Style S1) Converter: GD402G (General Purpose), GD402R (TIIS), GD402T (FM), GD402V (CSA) (Style S2) Note: When using GD40/402 as CE marking compliance product, select GD40G and GD402G. The related documents are as follows. General Specifications: GS 11T3E1-01E User’s Manual: IM 11T03E01-01E (this manual) * the “E” in the document number is the language code. An exclusive User’s Manual might be attached to the products whose suffix codes or option codes contain the code “Z” (made to customers’ specifications). Please read it along with this manual. The GD402 gas density meter and the GD40 detector not only provide continuous measurement of gas density, but also several other valuable parameters, including specific gravity and molecular weight. The GD40 detector is designed for intrinsically safe and flame-proof, explosion protected applications. It is designed to be virtually maintenance free for all accepted applications. The GD402 is a rugged microprocessor-based converter designed in two versions to meet both general area and explosion-proof application requirements. In addition to the display of several key data items, the converter also provides the choice of three different means for calibration: automatic; semi-automatic and one-touch manual operation. l Cross-Checking the Specifications CAUTION The GD402 gas density meter is shipped after adjusting the both of detector and converter in pairs. When installation, confirm whether the serial number on both of converter and detector are in pairs or not. If mismatched in pairs, converter is to be out of order. When converter or detector supplied individually, enter the detector constants, described on inside the lid of the GD40, into converter so that the GD402 is going to be well. In detail, please refer to Figure 5.30, Figure 6.31 or Figure 7.28. Upon delivery of the purchased product, unpack it carefully and make sure it is completely free from damage that may have occurred during transport. It must be shipped in strict conformance to the purchaser’s specifications. By way of precaution, confirm that the equipment is the exact model you ordered. Also check that all accessory components are included, when confirming the specifications, refer to the model and suffix codes indicated on the nameplate on the equipment. For a description of the model and suffix codes, refer to Chapter 1,’’Specifications.’’ l Consideration of Operation Parameters The GD402 operates with the same parameters set when it was delivered (default data) , when it is put into operation under these conditions.

Specifications> 1.1.2 1-4 GD40G, T, V, R Detector l Material exposed to gas SUS 316 stainless steel, Acrylonitrile Butadiene Rubber and Fluorine-contained Rubber (O-ring) l Ambient conditions Temperature: -10 to 60°C (14 to 140 °F) Humidity: 5 to 95%RH Installation: Pipe-mounted or on panel Construction: Explosion-proof and Intrinsically safe. (See 1.1.1 “System Components”)  hough the detector construction makes it relatively insensitive to sudden changes in T the gas temperature, extra precision can be achieved by keeping ambient temperature conditions as constant as possible. In measurements where optimum precision is required it is therefore not recommended to install the detector in an outdoors environment, especially not if such installation is prone to direct sunlight. l Finish Cover: Equivalent to Munsell 0.6GY3.1/2.0 Case: Equivalent to Munsell 2.5Y8.4/1.2 l Weight Approximately 7 kg (with pipe mounting bracket) l Detector unit When the system is ordered to be used as a hydrogen purity meter, an optional pressure transmitter is required for pressure compensation. • If /EJAJ1, /EJAF2, /EJAF3 or, /EJAF4 are ordered, the detector unit and the pressure transmitter and the tubing in between will all be integrated on a single mounting plate. This allows the space where the pressure transmitter is normally mounted to be used effectively for other purposes. 1.1.3 GD402G, T, V, R Converter l Display Reading: Digital (6 digits maximum; resolution: 0.0001 kg/m3) Data items shown: Measured value: Always on display.

Installation, Wiring and Piping> INSTALLATION, WIRING AND PIPING The GD402 Gas Density Meter is thoroughly inspected at the factory and carefully packed to ensure the equipment does not suffer any damage during transportation. The package should also be handled with care when unpacking to prevent the equipment from undergoing severe mechanical shock. After unpacking, visually check the equipment to ensure that it is free from any damage. Although the detector has no controls on it, it may need to be accessed for inspection or for other reasons. Install the detector in a location as close as possible to where the gas is sampled and where maintenance can be easily carried out. The converter has a display with controls on it; thus, you should install it so that the keys are positioned directly in front of you when working. Note that there must be a clearance of at least 400 mm at the back of the converter GD402G, GD402T, GD402V and GD402R since cables are wired to the back by removing the screwed rear cover. 2.1 Installing the Detector The GD40 detector is an explosion-proof with intrinsically safe sensor instrument. Install the detector in a location where the following conditions are satisfied. 2.1.1 Selecting the Location l Explosion-proof construction Before installing the detector in an explosion-hazardous area, ensure that the area conforms to the explosion-proof code noted above. l No corrosive gases Corrosive gases are not desirable because they may damage the electrical components in the detector. l Slight mechanical vibration Although the detector is vibration-resistant, vibration may loosen the connections of the external wiring. l No exposure to direct sunlight Exposure to direct sunlight may raise the temperature in the detector to abnormal levels, and should therefore be avoided. Note that such abnormal temperature levels can also result from heat irradiated from high-temperature equipment around the detector. l Humidity maintained between 5% and 95%RH Avoid choosing a location that is likely to be exposed to abnormally high or low humidity over a prolonged period. It is recommended that the detector be used at a humidity between 25% and 85 % RH. l No exposure to rain water Even though the detector is rainproof, whenever possible install it where it is protected from water splashes. The reasoning for this is that the detector cover may need to be removed for maintenance or for other reasons. l Altitude of installation site is lower than 2,000 m. IM 11T03E01-01E  2.1.2 2-2 <2.

Installation, Wiring and Piping> 2-10 Piping CAUTION In the case of replacement range, H2 in CO2 or Air in CO2, the output happen to be fluctuated by pressure loading to detector. In order to reduce the effect, flowmeter is to be set upper side of detector so that the pressure loading to the detector is going to be about atmospheric pressure. The piping connected to the analyzer comprises a line that feeds the gas under measurement to the detector, a line that returns (or releases to the atmosphere) the gas exhausted after measurement, and lines that carry the zero and span calibration gases. The type of piping chosen depends on the composition of the gas under measurement, its pressure, the amount of dust mixed, and the response (dead time). It is advisable however to use stainless steel piping of sizes from 6 mm and 4 mm in outer and inner diameters up to JIS 15 A (21.7mm in outer dia.). Refer to the following instructions when connecting the analyzer piping. l Figure 2.10, "System Configuration," shows an example of piping. Connect the lines securely to ensure that there is no gas leakage in the system. l Make sure the pressure of the sample gas is no greater than 0.5 MPa when measured at the detector inlet. If the pressure is too high, use a pressure reducing valve to regulate the pressure to a normal level. If the pressure is too low, it must be raised using a pump. l If the gas under measurement contains dust, mist or moisture, such impurities must be removed. Install a filter, mist separator or dehumidifier to remove these impurities from the gas. l In order to return the gas exhausted after measurement, the difference in pressure between the detector inlet and the point of returning the gas must be 0.5 kPa minimum. Choose piping with a large inner diameter to minimize pressure loss in the return gas line. l ALWAYS install a stop valve at the point where the gas is sampled (or returned). l The pressure transmitter for compensating pressure is designed to detect the pressure inside the detector; install a pressure lead pipe as close to the detector as possible (preferably, no more than 0.5 m away).

Inadvertent contact with those parts may result in electrical shock or injury. ALWAYS turn off the power to the meter before removing the rear or front cover by using external circuit breaker. This section explains how to wire the GD402 Analyzers. Note that this document is limited to the basic system configuration only (detector, converter and pressure transmitter). For details on the wiring of instruments used to receive analog output signals or contact output signals, see their respective instruction manuals. CAUTION The GD402 gas density meter is shipped after adjusting the both of detector and converter in pairs. When installation, confirm whether the serial number on both of converter and detector are in pairs or not. If mismatched in pairs, converter is to be out of order. When converter or detector supplied individually, enter the detector constants, described on inside the lid of the GD40, into converter so that the GD402 is going to be well. In detail, please refer to Figure 5.30, Figure 6.31 or Figure 7.28. CAUTION After wiring to the terminal block, do not push the remaining cables into the enclosure. 2.4.1 Wiring Procedure (1) The types of cables wired to the GD402 Analyzers are: (2) • Cable wired to power supply • Cable wired to detector input • Cables wired to output signals (two) -- or one signal if BRAIN communication is used • Cables wired to contact outputs (five) -- provided as necessary • Cable wired to contact input -- provided as necessary • Cables wired to pressure transmitter • Cables wired to the ground The GD402 converter has six cable inlets for external wiring. Wire the converter through cable glands. As a rule, choose cable glands as shown in Figure 2.11. IM 11T03E01-01E  2-13 <2. Installation, Wiring and Piping> Unit : mm (in.)

WARNING Cables that withstand temperatures of the least 75°C should be used for wiring. CAUTION The rear cover and the metal plugs at the external-wiring connections are fixed onto the converter case with hex setscrews. Before removing the cover, be SURE to loosen the setscrews. If you rotate the cover or a plug without loosening the setscrews, their threads may be severed, making the cover unremovable. When the rear cover or any of the cable glands or plugs are removed, handle them with utmost care so that the threads are not damaged. When re-attaching it on to the converter, clean the threads so they will not be damaged due to such foreign matters as dust. • • • Loosen the setscrews and remove the rear cover by rotating it counterclockwise. Guide the required external-wiring cables through the cable glands to the converter. Exercise care so as to avoid connecting them with the wrong polarities. After wiring, securely fasten the rear cover and cable glands. IM 11T03E01-01E  2-14 <2.

Installation, Wiring and Piping> 2-16 Cables Wired to Power Supply The GD402G bears the CE marking. When using the meter in a place where the CE marking is obligatory, or when performance meeting the CE marking requirements is needed, the following wiring is required. (Note that the following wiring is not required when the power supply is 24 V DC.) ● Install an external switch or circuit breaker to the power supply of the converter. ● Use an external switch or circuit breaker that is rated at 5 A and conforms to IEC 947-1 or IEC 947-3. ● Install the external switch or circuit breaker in the same room as the converter is installed. ● The external switch or circuit breaker should be installed in a location that allows operator access and should be marked a power supply switch to the converter. CAUTION The GD402R, T, V converter contains a power switch and a fuse. The switch cannot be operated however, if the converter is installed in an explosion-hazardous area; it must be left placed in the ON position. When Power ON/OFF, use external circuit breaker Wiring is for supplying power supply that meets specifications to the GD402 converter. Use a 3-conductor cable with a size of 1.25 to 2.5 mm2 and an outside diameter of 8 to 16 mm for 100-240 V AC type and a 2-conductor cable for 24 V DC type. Wire the cable as instructed below: (1) Strip the sheath 7 mm at the cable end to be connected to the converter. (2) Connect the cable to terminals L, N, and G or terminals + and - on the converter.

Choose the type of cables for a group of calibration-purpose contacts and for a group of other contacts separately. For wiring to the calibration contact output, use a cable of 8 to 16 mm in finished outer diameter and 1.25 mm2 minimum in thickness. For wiring to other contacts, use a cable of 8 to 16 mm in finished outer diameter and 0.13 to 1.25 mm2 in thickness, while choosing the number of core wires depending on the number of contacts used. Since the contact outputs are voltage-free, driving such devices as alarm lamps requires a separate power supply. For the contact input (start of calibration), provide a no-voltage signal. (Do not apply an external voltage.) Wire the cables as instructed below: (1) Use cables 0.13 to 1.25 mm2 thick. Treat the cable ends by stripping back the core wires to 7 mm from the end (see Figure 2.14). (2) Wire the cables to their respective given terminals on the block, being careful not to mistake one terminal for another. For terminal numbers assigned to the respective contacts I/Os, see Figure 2.12.

IM 11T03E01-01E  3.1.7 <3. Operation> 3-7 Checking the Analyzer for Performance When the required parameters have been completely set, bring into operation all equipment composing the measurement loop. Keep this equipment operating for a while. After making sure there is no problem with the equipment, go into normal operation. For reference, the following summarizes the setting functions (related to signals) of the GD402 analyzer that are used to obtain the optimum operating conditions. [Functions Related to the Output Signal] The output signal can be held at a value immediately before calibration or at a desired value during calibration or at the setting/service level. This is to prevent the output signal from adversely affecting the operation of the equipment configuring the measurement loop (default setting: the output signal is held at the value immediately before). [Functions Related to the High/Low Limit Alarm Contact Output] Select the parameters for which the alarms are raised, and then set their respective high/low limit set-points. The analyzer transmits an alarm contact signal if any of these setpoints is exceeded. (Define the voltage-free contacts and the state of contacts at the service level.) [Functions Related to the FAIL Contact Signal] If a FAIL state occurs, an appropriate message appears on the LCD display. For details on these functions, see Chapter 11. [Contact output of Hydrogen purity / Replacement meter] According to switching of Replacement meter, the status of contact and display (LED) is changed as following.

FAILURE: OPEN IM 11T03E01-01E  3.2 3-8 <3. Operation> Normal Operation In normal operation, there is no need for working with the GD402 analyzer except when calibrating it. Unless there is any failure found, carry out maintenance, inspection, and so on at the same time the analyzer is calibrated. The analyzer is designed to prohibit you from calibrating it or setting each parameter unless you have entered the password (XXX). (See section “4.2 Setting Lists”.) 3.2.1 Starting Operation Follow the procedure below to start operation. Turn on the external power switch. Set the operating parameters. Calibrate the analyzer for correct zero and span setpoints. Completing these steps return to the mode. F0307.ai The following details the operations required in this procedure. (1) The analyzer, when turned on, indicates the density value. See Figure 5.2, 6.3 or 7.3 for the operations used to change to the required unit of density. (2) Set the relevant operating parameters by checking and modifying their default values in order to meet individual operating requirements. (3) Supply the zero and span gases to check readings. If the readings contain errors, the analyzer must be calibrated. For details on calibration, see Chapter 8, 9 or 10. (4) When calibration is complete, the analyzer returns to the mode. 3.2.2 Corrective Actions in Case of Failure If the GD402 analyzer senses a failure, it sends out a FAIL contact output signal through terminals 18 and 19. In such a case, the output signal is held at either the value held immediately before or at the preset value for each setting. The message field indicates the type of error by the error code. Should a failure occur, check the nature of the failure and take corrective action without delay. Table 3.1 summarizes the numeric codes of errors that may occur in the measurement mode. For details on each type of error, see Table 11.2 on page 11-4.

Operation> 3-9 Inspection and Maintenance Due to the operating principle (polymodal self-excited oscillation circuitry), the sensor has only the slightest marginal drift, which is, in fact, generated by the detector itself or a result of contamination from dust, etc. Therefore, the GD402 analyzer basically does not have to undergo any inspection or maintenance. Periodical inspection and maintenance are recommended however, to ensure optimum performance. For details on inspection and maintenance, see Chapter 11. 3.3 Shutdown and Restart 3.3.1 Measures for Shutdown Data set in the converter are retained even when the power is turned off. If the system needs to be shut down over a prolonged period, turn off the power. Any foreign matter that accumulates and hardens on the detector or any corrosive substance that condenses on the detector can be the cause of problems. Fully purge the sensor with fresh air (instrument air). Cleaning of the sensor is also recommended where it is appropriate; consult Yokogawa. 3.3.2 Measures for Restarting Visually check all component equipment of the analyzer before you resume measurement after a long-term shutdown of the analyzer. Re-confirm the wiring and piping have tight connections . IM 11T03E01-01E Blank Page  4-1 <4. Functions> 4. FUNCTIONS When using the GD402 analyzer, set data and select functions according to the measuring conditions. This chapter describes the structures of function. 4.1 Summary of Setting Operations 4.1.1 Measurement, Operation, Setting and Service Parameters can be set by selecting the appropriate mode. These modes are classified into four levels: measurement, operation, setting, and service. [Measurement Level] This level is used to view various measured values. [Operation Level] This is basically a level used to select between items to be viewed in the measurement mode and a parameter to be measured, and to perform operations relating to routine inspection and/or maintenance such as calibration. [Setting Level] At this level, there are modes for setting data related to analog outputs, calibration data and alarm contact outputs. [Service Level] The GD402 analyzer has numerous functions. At this level, there are modes for selecting the functions necessary for system operation. 4.1.2 Key Operations Keys can be operated in an "interactive" manner. Operate the keys according to the information in the data or message field, information pointed to by the pointer (mode indication), and/or information in the key operation indicators. For basic key operations, see Subsection 3.1.4. [Interactions] l Flashing pointer This inquires whether you want to go to the mode being pointed at or move the pointer to the next mode. When the system indicates the modes for the setting or service level, the message is preceded by an asterisk (*). When you enter one of the modes, the pointer stops flashing and remains continuously lit. l Flashing key operation indicators This prompts you to choose an indicator from the indicators flashing on the display and press the corresponding key. l Flashing numerals in data field This asks whether you want to change the flashing numeral or move to the next digit and have it flash. Press the appropriate key. If neither of these actions is required, press the [ENT] key. [Aborting the Setting Operation] Press the [MODE] key. Normally, the [MODE] key is used to move from the measurement () mode to a mode at the operation level. It is also used to return to the measurement mode from other modes. IM 11T03E01-01E  4.1.3 <4. Functions> 4-2 Points to Be Noted When Making Settings (1) Password Password is not selected in first condition. When password is necessary, refer to Section “4.2 Setting Lists” and selected password what you need. If password is selected, you are not allowed to access any mode unless you enter the given password (XXX). A password prompt appears when: l at the operation level, the [MODE] key is pressed during the measurement mode, or l at the setting level, the [*] key is pressed during the measurement mode. l at the service level, the [YES] key is pressed with [*SERV] displayed. (2) Related Parameters If any change has been made to a particular parameter, check its relationship with parameters set in other modes so that there will not be any inconsistency. [Parameters to Check When the Analog Output Settings Are Changed] a. High/low limit alarm set-points and contact outputs b. Fixed value for held output signal [Parameters to Check When High/Low limit Alarm Set-points Are Changed] a. Alarm actions (low limit alarm or high limit alarm operation) b. Analog output settings 4.2 Setting Lists The GD402 Gas Density meter comes in 3 different models (and model codes) to meet several measurement conditions: (1) Density meter, (2) Calorie meter, and (3) Hydrogen purity meter. The values measured by the different models are as follows. (1) Density meter : Density, compensated density, specific gravity, molecular weight, concentration and calorie. (2) Calorie meter : Density, compensated density, and calorie (3) Hydrogen purity meter : Density, compensated density, H2 in Air, Air in CO2, and H2 in CO2. The following describes the conditions required when using the GD402 Gas Density meter. After following the procedure below, set a model code and select a password. (1) Select a model code for each service in “Selecting the instruments” function of each service code. For example, if you select model 1, you can use the analyzer as a calorie meter. (See Figure 5.29, Figure 6.30 or Figure 7.27.) code 0 : Density meter 1 : Calorie meter 2 : Hydrogen purity meter (2) Next, set a password, if you need. (See Figure 5.27, Figure 6.28 or Figure 7.25.) (3) Other parameter settings can now be set. Set parameters according to the selected model code and password.

Normally, the [MODE] key is used to move from the measurement () mode to a mode at the operation level. It is also used to return to the measurement mode from other modes. 6.2.1 Parameter Setting at Operation Level To move to the operation level, press the [MODE] key and then enter the password (XXX). Password is not selected in first condition. When password is necessary, refer to Section 4.2 “Setting Lists” and selected password what you need. The operation level offers two mode categories: the measurement and calibration operation modes. Note that the function for which you have set a data value at the setting level does not work at all if that function is turned off at another level. For this reason, care must be taken when dealing with modes that relate to each other. This subsection explains the operating procedures for the levels/modes noted below.

To use this feature, you must observe the following instructions. • The analyzer needs solenoid valves for controlling the calibration gases (zero and span gases). Connect the solenoid valves with utmost care to ensure that there is no gas leakage in the system. • Install the calibration gas cylinders in a location close to the GD40 detector. If the detector needs to be installed in an explosion-hazardous area, the solenoid valves being used must also be protected against explosion. • The contacts for controlling solenoid valves are built in the GD402T, GD402V, GD402R converter. It is the user's responsibility to supply power to drive the contacts. You must install a switch and a fuse along the power line.

HYDROGEN PURITY /CALIBRATION PROCEDURE This chapter describes how to calibrate of Hydrogen purity meter. If select Density meter, see Chapter 8. If select Calorie meter, see Chapter 9. Zero and span calibration can be carried out using standard gases (zero and span gases). The analyzer uses hydrogen (100%) as the zero gas and carbon dioxide (100%) as the span gas. The analyzer is designed so that calibration is done manually. The basic calibration procedures and operations are as follows. 10.1 Basic Calibration Procedure Operation level Manual calibration mode See the Process in Figure 7.2. See the Process in Figure 10.2.

INSPECTION AND MAINTENANCE To ensure the GD402 analyzer remains highly accurate with excellent operating conditions, routine inspection and maintenance is essential. Refer to the check items in this chapter to determine which items to apply in your inspection and maintenance, and check them periodically. 11.1 11.1.1 Routine Inspection and Maintenance Checking Readings and Calibrating the Analyzer Measure the standard gases every two to three months to check the output signal (Note: the interval varies depending on the operating conditions). If the output signal has errors, carry out zero and span calibration. For details on calibration, see Chapter 8, 9 or 10. 11.1.2 Checking the Flowrate of Sample Gas The sample gas should be supplied to the detector at 600 mL/min ±10%. Periodically make sure the given flowrate is kept constant. When checking the flowrate, also make sure the piping is normal and there is no leakage of calibration gases. 11.1.3 Periodic Replacement of the Detector's O-rings The O-rings are made from NBR, a material that is not very susceptible to plastic deformation. Their sealing capabilities therefore are not readily impaired. Any deterioration in these O-rings however can result in not only gas leakage but reduced resistance to mechanical vibration, which in turn may lead to reading errors. For this reason, it is recommended that the O-rings be replaced at a fixed interval (every two to three years). Consult Yokogawa for the replacement of O-rings. IM 11T03E01-01E  11.1.4 11-2 <11. INSPECTION AND MAINTENANCE> Replacing the Fuse (1) For safety reasons, stop the power supply to the converter by switching the external breaker. (2) Remove the fuse from the fuse holder. Turn the holder cap counterclockwise by 90 degrees using a flat-blade screwdriver that fits the holder cap. Then, pull out the fuse together with the cap. (3) Check that the rating of the new fuse is correct, and put it in the fuse cap; insert the cap (and fuse) in the holder; then while pressing down, turn the cap clockwise by 90 degrees using the flat-blade screwdriver. (4) If the new fuse breaks too soon, the circuit may be abnormal. Contact Yokogawa in such a case. Fuse Holder General purpose type Fuse Holder Explosion-proof type Figure 11.1 F1101.ai Position of the Fuse Holder 11.1.5 Cleaning Use a clean, soft cloth when cleaning for inspection or maintenance. You can use a neutral detergent on the transparent window of the non-explosion-protected converter (weatheringresistant PVC sheet), when extremely dirty. But do not use any organic solvent. If the device is so dirty and/or badly scratched that it affects key operation or reduces visibility, replace the case cover (part No.: K9313DW). IM 11T03E01-01E  11-3 <11. INSPECTION AND MAINTENANCE> 11.2 Inspection In Case of Failure 11.2.1 Inspecting the Analyzer in an Alarm Status The GD402 analyzer outputs an ALARM signal through terminals 16 and 17 if a failure is detected by the self-diagnostic function during measurement. In addition, the lamp on the operation panel comes on and the message field shows an alarm number. The analyzer outputs no contact signal, however, if the alarm number is [ALM.09]. If a failure (alarm) is detected, take the corrective action given in Table 11.1.
