General Specifications: GS 11T3E1-01E
User’s Manual:
IM 11T03E01-51E (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.

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 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.

<2. 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
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.

Installing the Converter
2.2.1
Selecting the Location
l Ease of operation
Select a location where you can easily view the readings on the display and work with the
keys. Installing the converter closer to the detector will ease your maintenance work, including
calibration.
l No corrosive gases
Corrosive gases are not desirable because they may damage the electrical components in the
converter.
l Slight mechanical vibration
Although the converter 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 converter 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 converter. If the converter is likely to
receive direct sunlight and the temperature in the converter will likely exceed the operating limits,
attach a hood (optional).
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 converter be used at a humidity between 25% and
85%RH.
l No exposure to rainwater
Even though the converter is rainproof, whenever possible install it where it is protected from

2.3 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).

2.4 Wiring
WARNING
Danger High Voltage !
Some parts of the meter’s internal assembly have high voltages. 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 following explains the general wiring procedure for each type of 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
glands to the converter. Beware of the correct polarities.
• After wiring, reinstall the terminal cover and front cover in place.

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.
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.
Loosen the terminal screw, insert the stripped part of the wire into the terminal hole,and fix
the cable by tightening the screw. (adequate tightening torque: 0.4 N·m)

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 finished 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 2.13).
(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 fix 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.)

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 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 2.13).
(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 fix the cables. (The appropriate tightening torque is 0.4 N·m)

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 finished 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 fit 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 terminal 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
Preparation for Operation
WARNING
• DO NOT supply power to the analyzer when inspecting it.
• Leave the power switch which is built in the converter, in the ON position.
• When using the converter under high ambient temperatures, be careful as the metal parts of
the converter will also be hot.
3.1.1
Inspecting Installation, Piping and Wiring
Workmanship
Before turning the power on, inspect workmanship with regards to installation, piping and wiring
as instructed below:
l Examine how the GD402 analyzer and its peripheral equipment are installed.
l Check the sample-gas line, which feeds the GD40 detector, for any gas leakage.
l Inspect the system to ensure that the GD402 analyzer and its peripheral equipment are
wired correctly. After inspection, shut the terminal box cover securely.
3.1.2
Supplying Power
First make sure that when the GD402 analyzer is turned on, no control instruments connected to
the analyzer will come into operation by the signals transmitted from the analyzer. Next, turn on
the external power switch to start the analyzer. At that point, make sure the internal power switch
is in the ON position if the converter is an explosion-protected model.
After power-on, the analyzer will begin to operate in the measurement mode.

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

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.

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 .

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.

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,

(3) Entries for Calorie and Concentration Measurement
Measuring the calorific value (or concentration) requires the density to be correlated with the
calorific value (or concentration) by a linear equation (linear proportion).
Therefore, use the gas calorie meter in order to measure the calorific value as accurately as
possible.
The relationship must be given by Y=aX+b, where Y is the calorific value (MJ/m3) and X is the
density (kg/m3).
l Example of Entries for Calorie Measurement
Assuming the relationship is given by “calorific value = 58 × density + 6 (MJ/m3)”, the density
ranges from 0.5 to 0.7 kg/m3 while the calorific 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:
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

Parameter Setting at Service Level
To move to the service level, select [*SERVC] at the setting level, and press the [YES] key.
(see Figure 5.3 on page 5-10.) The main task at the setting level is to set data values such as a
measuring range. To go into each mode of the service level, enter the appropriate code number.
CAUTION
DO NOT enter codes other than those listed in Table 5.4. A change to the settings of any unlisted
code can result in the failure of the analyzer to operate properly. If you have entered a wrong code
number by mistake, press the [MODE] key to return to the measurement mode().
You may exit the mode of that wrong code by pressing the [ENT] key, if you haven't made any
change to the relevant data.
(1)
When [*SERVC] is shown on the display, press
[YES] key. The message field changes to look
like the one shown left.
(2)
Press the [ENT] key with code number 01 shown
on the display, for example. The analyzer enters
the mode for setting the parameters of that code.

CAUTION
The instruments may not only work improperly but also big problems occur unless the detector
constants entered incorrectly. Do carefully and precisely when enter the detector constants into
converter.
1. The GD402 gas density meter is shipped after adjusting the detector and converter in pairs.
When installation, confirm 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.

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.

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.

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 9.
1. Analog output setting mode [*RANGE]
2. Calibration parameter setting mode [*CAL.DT]
3. Alarm-point setting mode [*ALARM]
4. Service level [*SERVC]
Select a mode from the above four choices. Each press of the [NO] key cycles through the
choices in sequence. Press the [YES] key to enter the desired mode when it is indicated.

Parameter Setting at Service Level
To move to the service level, select [*SERVC] at the setting level, and press the [YES] key.
(see Figure 6.4 on page 6-12.) The main task at the setting level is to set data values such as a
measuring range. To go into each mode of the service level, enter the appropriate code number.
CAUTION
DO NOT enter codes other than those listed in Table 6.4. A change to the settings of any
unlisted code can result in the failure of the analyzer to operate properly. If you have entered
a wrong code number by mistake, press the [MODE] key to return to the measurement
mode(). You may exit the mode of that wrong code by pressing the [ENT] key, if
you haven't made any change to the relevant data.

The instruments may not only work improperly but also big problems occur unless the detector
constants entered incorrectly. Do carefully and precisely when enter the detector constants into
converter.
1. The GD402 gas density meter is shipped after adjusting the detector and converter in pairs.
When installation, confirm 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.

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 10.
1. Analog output setting mode [*RANGE]
2. Calibration parameter setting mode [*CAL.DT]
3. Alarm-point setting mode [*ALARM]
4. Service level [*SERVC]
Select a mode from the above four choices. Each press of the [NO] key cycles through the
choices in sequence. Press the [YES] key to enter the desired mode when it is indicated.

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 set-points: 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) Output 1 [*OUT1]
(a) Select a parameter to be output.
Physical density [*DENS]
Compensated density [*C_DNS]
Hydrogen purity [*H_A] *1
Substituents-concentration [*H_C_A] *2
Gas temperature [*TEMP]
Gas pressure [*PRESS]
*1: Not selectable (i.e., not shown) if the analyzer is in the replacement (substituents-concentration) meter mode.
*2: Not selectable (i.e., not shown) if the analyzer is in the hydrogen purity meter mode.
(b) Set the zero and span points. (This item is not applied if temperature or pressure are
chosen as the parameter in item (a) above.)
Physical density [*Z_DNS], [*S_DNS]
Configure range:
00.0000 to 60.0000 (kg/m3),
0.00000 to 4.00000 (lb/ft3)
Compensated density [*Z_CP.D], [*S_CP.D]
Configure range:
0.0000 to 6.0000 (kg/m3),
0.00000 to 0.40000 (lb/ft3)
Hydrogen purity [*Z_H_A] , [*S_H_A]
Configure range:
0.0 to 100.0
Substituents-concentration [*Z_H.C.A] , [*S_H.C.A]
Configure range:
0.0 to 100.0
(2) Output 2 [*OUT2]
The same parameters as those of item (1) apply.
Note:If the same parameter is selected for both outputs 1 and 2, the zero/span point settings you made the last time apply when
the parameter is output.
Example: Assume you first select parameter [*H_A] for analog output [*OUT1] and set the zero/span points as 100.0/0.0, and
then select parameter [*H_A] for analog output [*OUT2] and set the zero/span points as 0.0/100.0. In that case, the
parameter is output with the 0.0/100.0 zero/span point settings for both outputs 1 and 2.

This setting determines whether or not the measured density should be compensated by the

transmitter or by using a fixed pressure set-point.
If you want the analyzer to compensate the density using a pressure transmitter, you MUST
connect a pressure transmitter to the converter and enter the pressure input and zero and span
points with CODE 12 at the service level.
If you do not want the analyzer to compensate the density, the analyzer shows and outputs the
measured density equivalent to a value at an atmospheric pressure of unity (101.33 kPa ABS)..

8.3 Calibration
8.3.1
Semi-automatic Calibration
In this mode of calibration, you can carry out one-touch calibration. 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.

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.

11. 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.

<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.

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).

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.
