2. INSTALLATION, WIRING AND PIPINGThe Model GD410 Gas Calorie 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 workingNote that there must be a clearance of at least 400 mm at the back of the converter, GD410S, since cables are wired to the back by removing the screwed rear cover.

2.1 Installing the DetectorThe GD300S detector is an intrinsically safe, explosionproof instrument (Exd [ia]IIB+H2T5). Install the detector in a location where the following conditions are satisfied.

2.1.1 Selecting the Location

l Explosionproof constructionBefore installing the detector in an explosion-hazardous area, ensure that the area conforms to the explosion proof code noted above.

l No corrosive gasesCorrosive gases are not desirable because they may damage the electrical components in the detector.

l Slight mechanical vibrationAlthough the detector is vibration-resistant, vibration may loosen the connections of the external wiring.

l No exposure to direct sunlightExposure 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 converter.

lHumiditymaintainedbetween5%and95%RHAvoid 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 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.



IM 11T03C01-01E

2.1.2 Mounting the Detector The detector is designed for pipe mounting of horizontal position. Measuring accuracy can be worse if you don’t horizontally install it.

2.2 Installing the ConverterThe GD410 converter comes in either the general purpose Model GD410G or explosion proof Model GD410S (explosion proof code: Exd IIB+H2T6). Choose the Model GD410S if the con-verter is to be used in a hazardous area.

2.2.1 Selecting the Location

l Ease of operationSelect 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 calibra-tion.

l Explosionproof constructionWhen installing the converter in an explosion-hazardous area, ensure that the area conforms to the explosionproof code noted above.

l No corrosive gasesCorrosive gases are not desirable because they may damage the electrical components in the detector.

l Slight mechanical vibrationAlthough the detector is vibration-resistant, vibration may loosen the connections of the external wiring.

l No exposure to direct sunlightExposure 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 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).

lHumiditymaintainedbetween5%and95%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 rainwaterEven though the converter is rainproof, whenever possible install it where it is protected from water splashes. The reasoning for this is that the converter cover may need to be removed for maintenance or for other reasons

2.3 PipingThe piping connected to the meter 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 measure-ment, and lines that carry the zero- and span-point 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 JIS-based SUS stainless-steel piping of sizes from 6 mm and 4 mm in outer and inner diameters up to JIS 15A (1/2 in.).Refer to the following instructions when connecting the meter piping. l Figure 2.7, "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 sampled 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 pip-ing 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 (prefer-ably, no more than 0.5 m away).

2.4 Wiring

WARNINGDangerHighVoltage!

Some parts of the meter’s internal assembly have high voltage. 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.

This section explains how to wire the GD410 meter. 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.

CAUTIONAfter 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 GD410o converter are:

・ 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

(2) The GD410o converter has six cable-inlets for external wiring. Wire the converter through cable glands. As a rule, choose cable glands as shown in Figure 2.8.

(3) The following explains the general wiring procedure for each type of converter.<Wiring the GD410S converter>

CAUTION

Wait 5 minutes after power disconnection, before opening the enclosure.

CAUTIONThe rear cover and the metal plugs at the external-wiring connections are fixed onto the convert-er 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 set screws, their threads may be severed, making the cover un-removable.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 set screws and remove the rear cover by rotating it counter clockwise.

・ 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.

2.4.2 Cable Wired to Power SupplyThis cable supplies the power complying with the specifications to the GD410o converter. Use a two-conductor cable of at least 1.25 mm2 thick to connect the power source to the terminal block of the converter. Be SURE to install a double-pole power switch externally.

CAUTIONThe GD410S converter contains a power switch and a fuse. The switch cannot be operated how-ever, if the converter is installed in an explosion-hazardous area; it must be left placed in the ON position, For this reason, install a power switch externally. When turning the switch on, BE SURE to simultaneously shutdown the lines of both polarities.

Wire the cable as instructed below:(1) Use a cable 1.25 to 2.5 mm2 thick. Treat the end of the cable by stripping the core wires

back to a length of 7 mm (see Figure 2.10).(2) Wire the cable to the L and N terminals on the block.

Loosen the terminal screws, insert the stripped ends of the core wires into the terminals, and fasten the screws to fix the cable.

2.4.3 Cables Wired to OutputsThese cables are used to transmit 4-20 mA DC signals and carry out BRAIN communication. Use shielded cables of 0.75 mm2 minimum in thickness (or a two-conductor shielded cable for single output).Wire the cables as instructed below:(1) Use cables 0.75 to 2.5 mm2 thick. Treat the cable ends by stripping the core wires back 7

mm (see Figure 2.10). (2) Wire the cable for out put 1 to terminals 3 and 4 on the block and the cable for output 2 to

terminals 5 and 6 on the block. Exercise care so as to avoid connecting the cables with the wrong polarities. Note that only terminals 3 and 4 (output 1) are effective for BRAIN commu-nication. Loosen the terminal screws, insert the stripped ends of the core wires into the terminals, and fasten the screws to fix the cable. (tightening torque: 0.4 Nm)

(3) Ground the shielding wire at a given terminal on the converter; do not ground the other end of the cable.

2.4.4 CablesWiredtoContactI/OsThe contact I/Os of the GD410o 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 con-tacts and for a group of other contacts separately.For wiring to the calibration contact output, use a four-conductor shielded cable 1.25 mm2 mini-mum in thickness. For wiring to other contacts, use an eight-conductor shielded cable of 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 sepa-rate 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 2.10).(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 2.9. 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 Nm.

2.4.5 Cable Wired to GD300S DetectorThe cable wired to the GD300S detector comes from the GD410o converter. Use a shielded ca-ble of 10 to 16 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 JIS M4-size (4-mm) crimp-on terminals to the ends of the core wires (see Figure 2.10). Connect the shielding wire to terminal 13 on the converter (see Figure 2.9).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 part number A1150WC). 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 2.12).

2.4.7 Cables Wired to the GroundWhen using the GD300S detector in an area requiring explosion protection, BE SURE to ground it as per the Class A Grounding Standard using a conductor of at least 2 mm2 in nominal thick-ness. The Class A ground terminal must be used for joining between converter and the earth cable as shown in Figure 2.14. For sealing wiring ports of the converter, use the explosionproof cable gland or the sealing fitting hardware.Also BE SURE to ground the GD410o converter as per the Class D Grounding Standard. Use No. 26 internal wiring terminals or the grounding terminals of the converter. (The appropriate tightening torque for the internal wiring terminals is 0.4 Nm.) Case-grounding terminal can be used as protective ground terminal. When using the detector's grounding terminals, attach M4 crimp terminals to the ends of the grounding cable. When crimping the terminals, use tools that fit the terminals.

3.1.5 Checking the Setting Parameters and Changes in Their Default Values

Set up the relevant parameters to meet individual operating requirements. The GD410 meter is designed to prohibit parameter setting unless you enter the password (331).The analog output range is factory-set to "0-133.000''. At the operation level, set the parameter “Density/ Convert-to-Calorie Factor” under the ADJUST mode and the parameter “Calorie Unit: MJ/Nm3“ under the DISP mode. Then, at the setting level, set the analog output.In the case of critical parameters, confirm that they are given correct settings even if the values set upon shipment from the factory (default values) will apply without needing any changes.Methods of changing the default values are detailed in Chapter 4. Refer to this information before you start setting parameters.

3.1.6 Calibrating the Meter for Correct ReadingsFor details on the calibration of the meter for correct readings, see Chapter 5.


<3. Operation> 3-7

IM 11T03C01-01E

3.1.7 Checking the Meter for PerformanceWhen 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 GD410 meter that are used to obtain the optimum operating conditions.[FunctionsRelatedtotheOutputSignal]

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).[FunctionsRelatedtotheHigh/Low-LimitAlarmContactOutput]

Select the parameters for which the alarms are raised, and then set their respective high/low-limit set points. The meter transmits an alarm contact signal if any of these set points is exceeded. (Define the voltage-free contacts and the state of contacts at the service level).[FunctionsRelatedtotheFAILContactSignal]

If a FAIL state occurs, an appropriate message appears on the LCD display. For details on these functions, see Chapter 6.

3.2 Normal Operation In normal operation, there is no need for working with the GD410 meter except when calibrating it. Unless there is any failure found, carry out maintenance, inspection, and so on at the same time the meter is calibrated. The meter is designed to prohibit you from calibrating it or setting each parameter unless you have entered the password (331).

3.2.1 Starting OperationFollow the procedure below to start operation.

↓

↓

↓

Completing these steps return to the <MEASURE> mode.

Turn on the external power switch.

Set the operating parameters.

Calibrate the analyzer for correct zero and span set points.

F3.5.ai

The following details the operations required in this procedure.(1) The meter, when turned on, indicates the calorific value. See Figure 4.1 for the operations

used to change to the required unit of calorie.(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 meter

must be calibrated. For details on calibration, see Chapter 5.(4) When calibration is complete, the meter returns to the <MEASURE> mode.

3.2.2 Corrective Actions in Case of FailureIf the GD410 meter 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 6.2.

3.2.3 Inspection and MaintenanceDue 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 GD410 meter basically does not have to undergo any inspection or maintenance. Periodic inspection and maintenance are recommended however, to ensure optimum performance. For details on inspection and maintenance, see Chapter 6.

3.3 Shutdown and Restart3.3.1 Measures for Shutdown

Data set in the meter 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 RestartingVisually check all component equipment of the meter before you resume measurement after a long-term shut down of the meter. Re-confirm the wiring and piping have tight connections .

4. PARAMETER SETTINGWhen using the GD410 analyzer, set data and select functions according to the measuring conditions. This chapter describes the procedures for setting various parameters.

4.1 Summary of Setting Operations4.1.1 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.[MeasurementLevel]

This level is used to view various measured values, and includes a mode for selecting between items to be viewed in the measurement mode and another for selecting a parameter to be measured.[OperationLevel]

This is basically a level used to perform operations relating to routine inspection and/or maintenance such as calibration.[SettingLevel]

At this level, there are modes for setting data related to analog outputs, calibration data and alarm contact outputs.[ServiceLevel]

The GD410 analyzer has numerous functions. At this level, there are modes for selecting the functions necessary for system operation.

4.1.2 Key OperationsKeys 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 for information in the key operation indicators. For basic key operations, see Subsection 3.1.4.[Interactions]

l Flashing pointerThis 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.lFlashingnumeralsindatafield

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.[AbortingtheSettingOperation]

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.

(2)Density/CalorieConversionFactorSettingMode[ADJUST]A caloric value is derived from the measured density value in the following equation, H=K1 x r +K0+K0_ADJWhere H is the caloric value, r is the density. K1, K0, and K0_ADJ are the conversion factors. Normally, K0 and K1 factors are automatically set (while the K0_ADJ factor is "0”) when the zero and span calibrations are performed with inputs of the density and the caloric value. After the calibration, an error may be generated between the actual caloric value of the gas of interest, Hm, and the reference caloric value, Hs, obtained from, for example, gas chromatograph. In this case the K0_ADJ factor is used to compensate for the error. Figure 4.2 illustrates how to set the factors.

・ As explained above, K0 and K1 factors are automatically set when the density and caloric values of the zero and span gases, respectively, are entered upon calibration. These factors can also be specified by direct input of the values in the [SET_K] mode.

・ When reference caloric value, Hs, is set for [VALUE] and actual measured value, Hm, is set for [CAL.SET] in the [AT_ADJ] mode, the compensation value for the error between Hs and Hm will be automatically set for [K0_ADJ]. Without setting values in the [AT_ADJ] mode, the same thing can also be achieved by direct setting of the compensation value for the error between Hs and Hm for [K0_ADJ]. If the compensation factor is set both through the [AT_ADJ] mode and by directly setting for [K0_ADJ], only the last-set factor will be valid.

4.3.3 Parameter Setting at Setting LevelTo move to the setting level, Press the [*] key and then enter the password (331).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 data setting mode is discussed in Chapter 5.1. Analog output setting mode 『*RANGE』2. Calibration parameter setting mode 『*CAL.DT』3. Alarm-point setting mode if 『*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.

You can abort the setting operation in any of the modes by pressing the【MODE】key.Doing this will return the analyzer to the measurement mode.

Three modes are available for calibration: automatic, semi-automatic (remote semi-automatic) and manual. Even if automatic calibration is enabled in the parameter setting, you can interrupt the system with either the semi-automatic or manual mode of calibration. The following explains the basic procedure and operation used in calibration.

5.3 Calibration5.3.1 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 GD300S 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 GD410S 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. Note that the contacts are rated at 250 V AC/3A or 30 V DC/3 A.

The 『ALM.10』 indication still remains on display even after the mode move to the measurement mode. This error massage does not disappear until normally ending in re-calibration or resetting the analyzer.*2: The values are operated and the calibration data are read at the time setpoint (calibration time) which is defined in the mode for setting automatics/semi-automatic calibration data in CODE 15. The display always shows the corrected density.*3: During automatic calibration, the display shows the same data items as those of the 『ZERO』 and subsequent indications.*4: When pressing the 【MODE】 key during 『ZERO』 or 『SPAN』 status, the 『WAIT』 appears on the display. When pressing the 【MODE】 key once again, the analyzer returns to the measurement mode. (This operation means you have cancelled automatic/semi-automatic calibration.)

5.3.2 Manual CalibrationIn this mode of calibration, you visually make sure the reading has settled, and then confirm the reading manually (by pressing the [ENT] key). There are two ways to switch between the zero, span and sample gases: by using manually-operated valves or by using solenoid valves. When switching between the gases using solenoid valves, follow the instructions on valve installation in Subsection 5.3.1.

5.3.3 Automatic CalibratioThis mode of calibration takes effect when you select “enable” for automatic calibration in CODE 13 『*AUTO.C』 at the service level. Even during automatic calibration, you can interrupt the system with the semi-automatic or manual mode of calibration. One cycle of automatic calibration is skipped, however, if the time of automatic calibration arrives when semi-automatic calibration is in progress.

CAUTIONDuring measurement after the calibration ends, the hydrogen density value might exceed 100 percent on the display, under the state that the hydrogen gas is filled and pressurized in the tank.This cause is in purity shortage of the density of the H2 gas when calibration. The H2 purity in the tank rises along with pressurizing the H2 gas. When the purity of the H2 gas exceeds the purity used for calibration, the density display exceeds 100.0%. At this time, the followings are recommended. It is waited to reach the highest pressure in the tank. Under such a condition, when it reaches the highest pressure, only zero calibration gas (H2) side is made.The operation is follows. Get out from the calibration screen by pushing [NO] key against the question of 『SPAN』 after the

『CAL SET』 screen of a normal zero gas calibration procedure is done in [ENT] key.


<6. Inspection and Maintenance> 6-1

6. INSPECTION AND MAINTENANCE To ensure the GD410 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.

6.1 Routine Inspection and Maintenance6.1.1 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, carried out zero- and span- point calibration. For details on calibration, see Chapter 5.

6.1.2 Checking the Flow rate of Sample GasThe sample gas should be supplied to the detector at 0.1 to 1.0 l/min. Periodically make sure the given flow rate is kept constant. When checking the flow rate, also make sure the piping is normal and there is no leakage of calibration gases.

6.1.3 Periodic Replacement of the Detector's O-ringsThe 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 11T03C01-01E

6.1.4 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 counter clockwise by 90 degrees

using a flat-blade screw driver 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-blades crew driver.

(4) If the new fuse breaks too soon, the circuit may be abnormal. Contact Yokogawa in such a case.

6.1.5 CleaningUse a dry, 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 (weathering-resistant 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. : K9215JA).

6.2 Inspection In Case of Failure6.2.1 Inspecting the Analyzer in an Alarm Status

The GD410 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 <ALARM> 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 6.1.
