The GD402 gas density meter and the GD40 detector not only provide continuous measurement
of gas density, but also several other valuable parameters, including specic gravity and molecular weight. The GD40 detector is designed for intrinsically safe and ame-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.
Before use, read this manual thoroughly in order to fully realize the capabilities of the Meter.

(For Explosion-proof use)
Part No.Description
L9811LLG3/4 explosion-proof cable gland.
Cable’s outside diameter 8 to 16 mm.
Used for the GD402R converter.
Note: Specify the number of cable glands for converter in hazardous area
1.2.4 Two-core, Double-Shielded Cable
Normally two conductor shielded cable can be used, but when failure arises from noises
disturbance, this cable is recommended for connection between the GD402 converter and
GD40 detector.
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 satised.
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.

In the case of replacement range, H2 in CO2 or Air in CO2, the output happen to be uctuated by
pressure loading to detector. In order to reduce the effect, owmeter 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 Conguration," shows an example of piping. Connect the lines secure-
ly 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.
2-10
l If the gas under measurement contains dust, mist or moisture, such impurities must be
removed. Install a lter, mist separator or dehumidier 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).

CAUTION
The rear cover and the metal plugs at the external-wiring connections are xed 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.
<Wiring the GD402G converter>
• Loosen the setscrews in the four corners and remove the front cover.
• Remove the terminal cover. Guide the required external-wiring cables through the cable

2.4.2 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.
● Connect the supplied surge protector to the power supply. This protects the power supply
circuit of the converter from surge.
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
2-16
Wiring is for supplying power supply that meets specications 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. A surge protector is not provided with the GD402T, V, R type converter.
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.
Loosen the terminal screw, insert the stripped part of the wire into the terminal hole,and x
the cable by tightening the screw. (adequate tightening torque: 0.4 N·m)
(3) The length of wire between the converter and a connecting device for the surge protector
should not exceed 1 m.
(4) To connect the surge protector, use a terminal box or relevant device. Wires of the surge
protector have a M4 ring terminal crimped.
(5) Connect black cables of the surge protector to terminals L and N, and the green cable to
terminal G. (Terminal G is internally connected to the case-grounding terminal.)

2.4.3 Cables Wired to Outputs
These cables are used to transmit 4-20 mA DC signals and carry out BRAIN communication.
Use shielded cables of 8 to 16 mm in nished outer diameter and 0.75 mm2 minimum in thickness (or a two-core shielded cable for single output).
Wire the cables as instructed below:
(1) Use cables that are 0.75 to 2.5 mm2 thick. Treat the cable ends by stripping the core wires
back 7 mm (see Figure 2.14).
(2) Wire the cable for output 1 to terminals 3 and 4 on the block and the cable for output 2 to
terminals 5 and 6 on the block. Beware of the correct polarities. Note that only terminals 3 and
4 (output 1) are effective for BRAIN communication.
Loosen the terminal screws, insert the stripped ends of the core wires into the terminals, and
fasten the screws to x the cables.
(3) Ground the shielding wire at a given terminal on the converter; do not ground the other end of
the cable. (The appropriate tightening torque for the internal wiring terminals is 0.4 N·m.)

<2. Installation, Wiring and Piping>
2.4.4 Cables Wired to Contact I/Os
The contact I/Os of the GD402 converter comprise the start-of-calibration contact (input), the
FAIL, ALARM and MAINTENANCE contacts, and the contacts for operating the solenoid valves
for span and zero calibrations. 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 nished outer diameter
and 1.25 mm2 minimum in thickness. For wiring to other contacts, use a cable of 8 to 16 mm in
nished 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 voltage-free signal.
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.
Loosen the terminal screws, insert the stripped ends of the core wires into the terminals, and
fasten the screws to x the cables. (The appropriate tightening torque is 0.4 N·m)

2.4.5 Cable Wired to GD40 Detector
The cable wired to the GD40 detector comes from the GD402 converter. Use a shielded cable
of 10 to 13.5 mm in nished outer diameter that suits the dedicated cable gland. Wire the cable
through the cable gland, being careful not to connect the cable with the wrong polarities. Attach
M4 crimp terminals to the ends of the core wires (see Figure 2.14). Connect the shielding wire to
terminal 13 on the converter (see Figure 2.12). When crimping the terminals, use tools that t the
terminals.
If a malfunction occurs and it is assumed to be due to noise, use a double-shielded cable (for example, the cable with Yokogawa’s Model GDW-L ). Connect the outer shielding wire to ter-
minal 13 on the converter and the other end of the wire to the grounding terminal on the detector.
Connect the inner shielding wires to the grounding terminal on the converter (see Figure 2.17).

3.1.6 Calibrating the Analyzer for Correct Readings
For details on the calibration of the analyzer for correct readings, see Chapter 8, 9 or 10.
IM 11T3E1-01E
<3. Operation>
3.1.7 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 conguring 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
setpoints. The analyzer transmits an alarm contact signal if any of these setpoints is exceeded.
(Dene 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.

<3. Operation>
3.2 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 <MEASURE> mode.
3-8
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 ana-
lyzer must be calibrated. For details on calibration, see Chapter 8, 9 or 10.
(4) When calibration is complete, the analyzer returns to the <MEASURE> 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 eld 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.

<3. Operation>
3.2.3 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-conrm the wiring and piping have tight connections .

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 classied 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]
4-1
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 eld, 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 ashing and
remains continuously lit.
l Flashing key operation indicators
This prompts you to choose an indicator from the indicators ashing on the display and press
the corresponding key.
l Flashing numerals in data eld
This asks whether you want to change the ashing numeral or move to the next digit and have
it ash. 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
(<MEASURE>) mode to a mode at the operation level. It is also used to return to the measurement mode from other modes.

4.1.3 Points to Be Noted When Making Settings
(1) Password
Password is not selected in rst 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.

5.2.2 Parameter Setting at Setting Level
To move to the setting level, press the [*] key and then enter the password (XXX). The main task
at the setting level is to set data values such as the measuring range values.
Note that the function for which you have set data values at the setting level, will not work 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. The setting level has four levels/modes, as shown below, although this subsection explains only the analog output setting and alarm-point setting modes.
The calibration parameter setting mode is discussed in Chapter 8.

1. Analog Output Setting Mode [ *RANGE ]
The analog output has output 1 and output 2. Only output 1 can be used for communication
purposes.
Set a range appropriate for 4-20 mA DC output signals. The range has two setpoints: the lower
limit (zero point) of the range corresponding to the minimum (0%) of a given output signal and the
upper limit (span point) of the range corresponding to the maximum (100%) of the given output
signal.
(1) Output1 [*OUT1]
(a) Select a parameter to be output.
・ Physical density [*DENS]
・ Compensated density [*C_DNS]
・ Specic gravity [*SP_GR]
・ Caloric value [*CALRY]
・ Molecular weight [*MOL]
・ Concentration [*CONCT]
・ Gas temperature [*TEMP]

・ Gas pressure [*PRESS]
(b) Set the zero and span points. (This item is not applied if temperature or pressure are cho-
sen as the parameter in item (a) above.)
・ Physical density [*Z_DNS], [*S_DNS]
Congure range: 00.0000 to 60.0000 (kg/m3),
0.00000 to 4.00000 (lb/ft3)
・ Compensated density [*Z_CP.D], [*S_CP.D]
Congure range: 0.0000 to 6.0000 (kg/m3),
0.00000 to 0.40000 (lb/ft3)
・ Specic gravity [*Z_SPC], [*S_SPC]
Congure range: 0.0000 to 5.0000
・ Caloric value [*Z_CAL], [*S_CAL]
Congure range: 000.000 to 133.000(MJ/m3),
0.0000 to 3.5000 (kBTU/ft3)
・ Molecular weight [*Z_MOL], [*S_MOL]
Congure range: 000.00 to 140.00
・ Concentration [*Z_CON], [*S_CON]
Congure range: 000.0 to 100.0

<5. DENSITY / PARAMETER SETTING>
(3) Entries for Calorie and Concentration Measurement
Measuring the caloric value (or concentration) requires the density to be correlated with the
caloric value (or concentration) by a linear equation (linear proportion).
Therefore, use the gas calorie meter in order to measure the caloric value as accurately as possible.
The relationship must be given by Y=aX+b, where Y is the caloric value (MJ/m3) and X is the
density (kg/m3).
l Example of Entries for Calorie Measurement
Assuming the relationship is given by “caloric value = 58 × density + 6 (MJ/m3)”, the density
ranges from 0.5 to 0.7 kg/m3 while the caloric value ranges from 35 to 46.6 MJ/m3.
The entries for the [*CALRY] parameter (see Figure 5.4) therefore are:
*Z_CAL: 35
*S_CAL: 46.6
*Z_CL.D: 0.5
*S_CL.D: 0.7
l Example of Entries for Concentration Measurement
Assume we measure the concentration of hydrogen mixed with nitrogen and the relationship
is given by:
5-12
D = aX +b
where,
D=density of gas being measured (hydrogen: 0.0899 kg/m3; nitrogen: 1.2504 kg/m3),
and
X=volume percent (vol %) of hydrogen gas,
then the equation above is calculated as:
D= (0.0899-1.2504)(X/100) + 1.2504
= -1.1605(X/100) + 1.2504

CAUTION
The instruments may not only work improperly but also big problems occur unless the detector

converter.
1. The GD402 gas density meter is shipped after adjusting the detector and converter in pairs.
When installation, conrm the converter serial number described on the label of detector so
that combines converter and detector correctly. If mismatched in pairs, converter may be out
of order. If combined correctly, no need to enter the detector constants again, as converter
has been adjusted with the constants in factory.
2. When supply converter or detector individually, enter the detector constants, described on
inside the lid of the GD40, into the converter so that the GD402 is going to be well.

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.
The calibration operation mode is discussed in Chapter 9.
In order to this mode, select “MAN.CAL” in before page, and press [YES] key.
This mode is used to set a factor for converting density to calorie. This setting is mandatory when
measuring the calorie.
(a) Automatic zero-point adjustment [AT_ADJ] : 0 to 133.000, 0 to 3.5000
(b) Factor setting [SET_K] :
• Zero point [K0_ADJ] : -99999 to 99999
• K0 [K0] : -99999 to 99999
• K1 [K1] : 0 to 99999
Note: The result of executing item (a) above is also reected on [K0_ADJ] in item (b).

*1: See "Figure 6.1 Modes of Operation Level" on page 6-8.
*2: Using the [ ], [ ] and [ENT] keys, set a value (numeral position of the decimal point and sign).
Each press of the [ ] key moves through the fields of the numeral decimal point and sign in this order.
If you enter a value that exceeds the limits, the display shows [*OVER].
Press the [YES] or [NO] key to re-set the value.
*3: Set a value using the [ ], [ ] and [ENT] keys.
*4 When the reading stabilizes, press the [ENT] key to confirm the factor.
This parameter does not accept input from the [ ] and [ ] keys.

(3) Display Mode
Select one of the following seven parameters to be shown in the message eld. Each press of
the [NO] key cycles through the choices in the order shown below:
1. Physical density [XX.XXXX KG/M3] or [XX.XXXX LB/FT3]
(depends on the setting of CODE 21)
2. Compensated density [X.XXXX KG/M3 ]or [X.XXXXX LB/FT3]
(depends on the setting of CODE 21)
3. Caloric value [XXX.XXX MJ/M3] or [XX.XXXX KBTU]
(depends on the setting of CODE 22)
4. Temperature [XXX.X °C] or [XXX.X °F]
(depends on the setting of CODE 23)
5. Pressure [XXX.XX KPA] or [X.XXXX MPA] or [XX.XXX PSI]
(depends on the setting of CODE 20)
6. Current for analog output 1 (%) [XXX.X MA1%]
7. Current for analog output 2(%) [XXX.X MA 2%]
Show the desired choice and press the [YES] key. That choice is set as a parameter to be measured in the measurement mode (<MEASURE>). Parameters 1, 2 and 3 are congurable, while
parameters 4 to 7 are read-only.
