1. General
1.1 e apparatus protected by the ameproof enclosure in accordance with EN 60079-1 can be installed in such hazardous areas, for which the apparatus has been certied, as an explosive atmosphere containing ammable substances in the form of gas, vapour, mist or dust may be present.
Note: e apparatus has been certied to comply with EN 61241-0, EN 61241-1
(dust ignition protection).
1.2 The apparatus enclosure must be kept closed in the hazardous areas when the apparatus is energized because the internal circuit of the apparatus is capable of igniting the explosive atmosphere. (Never connect any hand-held communicator to the apparatus terminals by opening the cover, except while no explosive atmosphere is present.)
1.3 It is required to connect the external earthing terminal of the apparatus to the equipotential bonding system which includes protective conductors, metal conduits, metal cable sheaths, steel wire armouring and metallic parts of structures, but does not include the neutral conductors of the power systems.
Note: e protective conductor to which exposed conductive parts of equipment
(machines, apparatus, devices, components and instrumentation thereof) are connected, must be separated in the hazardous area from the neutral conductor, and must be connected to the power systems earth point in the non-hazardous area, if the power system is directly earthed.
For external earthing and bonding of the apparatus it is recommended to use
a cable lug so that the conductor is secured against loosening and twisting and that the contact pressure is permanently secured.
1.4 Either cable systems (cable entry systems) or conduit systems can be employed for wiring of the apparatus in the hazardous areas (see 2 or 3).
1.5 Non-sheathed single core cables are not permitted for live conductors unless they are installed inside enclosures or conduit systems.
1.6 Conduits and, in special cases, cables (for example, where there is a pressure difference) must be sealed so as to prevent the passage of the explosive atmosphere.
1.7 Further information concerning installation and maintenance of apparatus is given by relevant clauses of the following documents.
EN 60079-14 Electrical apparatus for explosive gas atmospheres
EN 60079-17 Part 17: Inspection and maintenance of electrical installations in
EN 50281-1-2 Electrical apparatus for use in the presence of combustible dust

2. Cable systems
2.1 Thermoplastic sheathed cables, thermosetting sheathed cables, or elastomeric sheathed cables can be selected for xed wiring in the hazardous
areas.
2.2 Flameproof cable entry devices (cable glands) certified to comply with EN 60079-1 and appropriate to the type of cable employed, must be used for the connection of cables to the apparatus.
3. Conduit systems
For conduit systems, relevant national standards or codes of practice are followed prior to the following recommendations.
3.1 Screwed heavy gauge steel, solid drawn or seam welded conduit, or exible conduit for protection of cables in explosive atmospheres (see ISO 10807) can be selected for xed wiring in the hazardous areas.
3.2 Conduit must be threaded for connection to permit the full engagement of ve threads.
3.3 Either conduit entry devices or sealing devices such as stopping boxes are provided at the wall of the apparatus enclosure to limit the pressure piling eect and to prevent hot gases from entering the conduit system from the enclosure containing a source of ignition. Each type of both the devices must be certied to comply with EN 60079-1.
3.4 The stopping boxes, if used, are filled with a compound which does not shrink or setting and is impervious to, and unaected by, chemicals found in the hazardous area. e depth of the compound in the stopping box is at least equal to the internal diameter of the conduit, but in no case less than 10 mm.
3.5 When the conduit contains three or more non-seathed single or multi-core cables, the total cross-sectional areas of cables, including insulation, are not more than 40% of the cross-sectional area of the conduit.
4. Installation in explosive atmospheres caused by air / dust
mixtures
4.1 Conduit or cable glands, if employed to connect cables to the apparatus, must be selected and used in such a way that an IP6X protection (dust-tight) is guaranteed.
4.2 It is recommended to maintain the apparatus so that the dust layer will not
exceed a thickness of 5 mm.
Note: Where the ignition temperature of a dust layer up to 5 mm thickness is
equal to, or higher than, the value that is obtained by adding 75K to the maximum surface temperature of the enclosure “T...°C” as marked on the apparatus, the apparatus is incapable of causing ignition of the dust layer. (T...°C is based on the maximum ambient temperature)

2-4-1. Fieldbus requirements

Fieldbus components and characteristics
Cable
Various types cables are usable for fieldbus. Type A is the preferred fieldbus cable. Azbil Corporation recommends type A as the fieldbus cable to use.
Fig. 2-18 HGM folder properties
2-25
Page 48
The table below describes the type of cable and its maximum length, which is specified in the IEC 1158-2/ISA S50.02 Physical Layer Standard.

Terminators
A terminator is an impedance matching module used near or at the end of a transmission line. Terminators prevent distortion and signal loss. A terminator shall be located at both ends of a trunk cable, connected from one signal conductor to the other. A trunk is the longest cable path between any two devices on the fieldbus network. ONLY TWO terminators are required per fieldbus segment. No connection shall be made between the terminator and cable shield.
2-26
Page 49
The terminator impedance value shall be 100 ohm +/- 2% over a frequency range of 7.8 kHz to 39 kHz. The model HGC303 and model HDM303 have a terminator at the fieldbus connection port therefore an additional terminator is not required.
Terminal blocks
The terminal blocks can be the same as those used for 4-20mA.
Connectors
D-sub 9P connector is as specified for standard fieldbus connectors in the IEC/ISA Standard.

2-4-2. Fieldbus wiring

Signal wire
A Fieldbus signal is transmitted via 2-wire isolated signal lines. Please keep in mind that the Fieldbus signal has polarity, positive (+) and negative (-). All of the (+) terminals must be connected to each other and similarly, all of the (-) terminals must be connected each other. An important aspect of fieldbus is that neither of the signal wires are grounded.
Shielding
The preferred type of cable for fieldbus is a shielded cable. Assemble a lugged shield wire connected to the metallized shield of each cable. Connect all shield wires together to the terminal block. In addition, connect the overall shield to the ground at one point in instruments room to protect against field noise. Do not ground the shield at multiple points.
Termination
A terminator shall be connected at both ends of the signal wire pair, at the field device end and the host device end. Connect the terminator between signal (+) and (-). ONLY TWO terminators are needed per fieldbus segment. Never connect a terminator between the signal (+ or -) and cable shield.

3-1-3. Power on

Supply the power to operate the model HGC303 system according to the following action.
Table 3-2. The procedure to start up the model HGC303 system
Step Action
1 Supply the valve operating gas
2 Supply the carrier gas pressure
3 Supply the power to the model HGC303
4 Supply the power to the model HDM303
5 Wait until the model HGC303 system becomes stable.
6 Supply the process/standard gas*+
Note: After turning on the power, allow 2 hours for the device to warm up.
The carrier gas pressure SP and oven temperature SP have already been factory set in the model HGC303, therefore, the user doesn’t have to worry about setting this data. Carrier gas pressure SP: less than 300 kPa (43.5 psi) (SP differs with each model HGC303) Oven temperature SP: 58°C (136.4°F) Analyzing cycle: 300 sec.
Note: When the power is supplied to the model HGC303, a model HGC303 status error will
appear on HGM monitoring system (oven temperature error message etc.
This is because of a self-diagnostic system error, not a model HGC303 system error.
The model HGC303 status will automatically return to normal once the oven
temperature reaches 58°C (136.4°F).
Note *: Recommend supplying the standard gas if it is the first time set-up after delivery or
a long-period storage.
Note +: If the output value from HGC seems strange after several cycles supplying the
process gas, try to do followings:
1. Check the process/standard gas supplies properly and the vent line is not blocked. If there are problems, rectify them and check the output value again.
2. Run the HGM program, and make it “on-line”, then start “User’s mode”.
3. Check whether the peaks are small or normal, the peak shapes are strange or not by chromatogram.
4. If the phenomena in section above are observed, stop the process gas and quite the HGM program.
5. Connect blind plugs or shut the vent lines, then connect Helium gas cylinder at the ‘INLET’ port of HGC.
6. Charge Helium gas at 400kPa (58psi) to ‘INLET’ then leave it for about one hour.
7. Return the connection normal and supply process/standard gas for checking again.

Table 3-3. Model HGC303 leak test procedure
Step Action
1 Check that the valve operating gas is being supplied.
2 Check the carrier gas has a secondary pressure (A) of 400 ± 50 kPa (58 ± 7 psi).
Verify that the carrier gas line valve off and observe the rate of fall in the
3
indicated primary pressure (B).
Leak evaluation procedure. After introducing the carrier gas into the model HGC303, a normal condition is confirmed by a rate of fall of less than 1500 kPa (217 psi) per every 5 minutes.If more than 1500 kPa (217 psi) is observed, immediately contact an Azbil
4
Corporation products service office or the nearest distributor. If the carrier gas is being used for valve operating gas at the same time, the carrier gas consumption will be doubled. (less than 3000 kPa (435 psi) per 5 minutes)

(4) Output setting in Auto Calibration
Data update to the HDM during auto or semi-auto calibration can be selected after executing auto or semi-auto calibration.
- Hold [default]
- Calibration data (New RF) If “Hold” is selected, the HGC does not update the data to the HDM during auto/semi-auto calibration. If “Calibration data (New RF)” is selected, the HGC updates the data to HDM after the calibration. This case, HGC transmits “New Response factor (New RF)” of PV1 to 11 to the HDM instead of the components’ concentration. Refer to the description of RF (response factor) in 3-4-2. Calibration procedure for the “Response Factor”.
An example of a difference between “Hold” and “Calibration data (New RF)” is shown below. Setting data: Time: 6:00 Hold time: 30 minutes

3-4. Calibration

The device has already been calibrated at the factory but we recommend that you recalibrate it with your own calibration gas to ensure the accuracy of analysis in the following cases: 1 When the model HGC303 is newly installed. 2 When an unused model HGC303 is started up again. 3 At a calibration interval decided by the user. (Recommended calibration cycle is every 6
months.)
4 After the model HGC303 has been repaired or its parts have been replaced.

3-4-1. Calibration gas requirement

1 It is imperative that the composition of the calibration gas should resemble the process gas. If the process gas concentration is high and calibration was done using a low concentration
gas, the chance for error may increase. 2 The unit for calibration gas concentration should be mol%. 3 Methane gas should be contained in case of N2 calibration. 4 Ethane(C2H6) should be contained in the calibration gas to avoid “Retention time lock
error”.
