User’s Manual Model GD402 Gas Density Meter IM 11T3E1-01E R IM 11T3E1-01E 7th Edition (YK)
i Introduction 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.
ii 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.

3. 3-1 <3. Operation> OPERATION This chapter explains how to operate the GD402 Analyzers. 3.1 Preparation for Operation CAUTION (1) DO NOT supply power to the analyzer when inspecting it. (2) Leave the power switch which is built in the converter, in the ON position. (3) DO NOT open the terminal box cover with the power turned on, if the analyzer is installed in an explosion-hazardous area.
3.1.2 <3. Operation> 3-2 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.
3.1.3 3-3 <3. Operation> Display on Operation Panel and Operation Keys Figures 3.1 and 3.2 illustrate the operation panels of the Model GD402G and GD402T, GD402V, GD402R converters, respectively. The operation panel has a display and operation keys. Use the seven operation keys on the panel to set operation parameters, and so on.

3.1.4 3-4 <3. Operation> Basic Key Operation The basics of key operation are the selection between modes/levels, the selection and execution of the function/action, and entry of data values. 1. Selecting Between Modes at the Operation Level (See Chapter 5, 6 or 7 for details.) l You can enter the measurement mode by pressing the [MODE] key while the analyzer is in a mode other than the measurement mode. When switching between modes, note the following two points: (1) Press the [MODE] key once.
3-5 <3. Operation> 3. Entering Data Values NOTE The data you have entered keep in memory even if you turn off the power. If the data you have entered are provisional, reenter the normal data. The following explains how to make changes to existing data entries. In the display shown in Figure 3.4-(2), pressing the [YES] key causes the message field to default to [*DENS].
3-6 <3. Operation> 4. Entering a Password If you need, a password can be entered to proceed into the operation, setting or service level. When you attempt to enter that level, a password-entry message (password prompt) like one shown in Figure 3.6-(1) appears. The required password is “XXX”. (See section “4.2 Setting Lists”.) (1) (2) When password is selected, pressing the [MODE] key, then the [*] key, changes the display to look like this. Type the password (XXX) and then press the [ENT] key.
3.1.7 <3. Operation> 3-7 Checking the Analyzer for Performance When the required parameters have been completely set, bring into operation all equipment composing the measurement loop. Keep this equipment operating for a while. After making sure there is no problem with the equipment, go into normal operation. For reference, the following summarizes the setting functions (related to signals) of the GD402 analyzer that are used to obtain the optimum operating conditions.
3.2 3.2.1 3-8 <3. Operation> Normal Operation In normal operation, there is no need for working with the GD402 analyzer except when calibrating it. Unless there is any failure found, carry out maintenance, inspection, and so on at the same time the analyzer is calibrated. The analyzer is designed to prohibit you from calibrating it or setting each parameter unless you have entered the password (XXX). (See section “4.2 Setting Lists”.
3.2.3 <3. Operation> 3-9 Inspection and Maintenance Due to the operating principle (polymodal self-excited oscillation circuitry), the sensor has only the slightest marginal drift, which is, in fact, generated by the detector itself or a result of contamination from dust, etc. Therefore, the GD402 analyzer basically does not have to undergo any inspection or maintenance. Periodical inspection and maintenance are recommended however, to ensure optimum performance.

5-7 <5. DENSITY / PARAMETER SETTING> 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.

5.2.2 5-10 <5. DENSITY / PARAMETER SETTING> 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.
5-11 <5. DENSITY / PARAMETER SETTING> 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.
5-12 <5. DENSITY / PARAMETER SETTING> (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).
