(1) Installation for ISSeP/ATEX Flameproof Apparatus

1. General

1.1 The apparatus protected by the flameproof enclosure in accordance with EN
50018 can be installed in such hazardous areas, for which the apparatus has been
certified, as an explosive atmosphere containing flammable substances in the form
of gas, vapour, mist or dust may be present.

~Note The apparatus has been certified to comply with EN 50281-1-1 (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 The 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

Part 14: Electrical installations in hazardous areas other than mines

EN 60079-17 Part 17: Inspection and maintenance of electrical installations in

hazardous areas.

EN 50281-1-2 Electrical apparatus for use in the presence of combustible dust

Part 1-2: Electrical apparatus protected by enclosures

Safety Yamatake Corporation

2. Cable systems

2.1 Thermoplastic sheathed cables, thermosetting sheathed cables, or elastomeric
sheathed cables can be selected for fixed wiring in the hazardous areas.

2.2 Flameproof cable entry devices (cable glands) certified to comply with EN 50018
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 flexible
conduit for protection of cables in explosive atmospheres (see ISO 10807) can
be selected for fixed wiring in the hazardous areas.

3.2 Conduit must be threaded for connection to permit the full engagement of five
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 effect
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 certified
to comply with EN 50018.

3.4 The stopping boxes, if used, are filled with a compound which does not shrink
or setting and is impervious to, and unaffected by, chemicals found in the
hazardous area. The 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)

 CAUTION

A block valve is a kind of air actuator valve. It is used mainly for the protection of
the TCD and columns.

It works as sample shut-off valve when the pressure of the carrier gas or air supply
is lower than approximately 294 kPa.

Yamatake recommends that it should be installed.

The Heat Value Gas Chromatograph measures process gases (N2, CO2, C1~C6+) that
are mainly contained in natural gas, calculates heat value, density, Wobbe index and
compressibility factor, and converts them into a Fieldbus signal in the field and trans­mits the signal to receivers.

Parameters can be remotely set, adjusted, and self-diagnosed with the HGM.

Fieldbus components and characteristics

Cable

Various types cables are usable for fieldbus.

Type A is the preferred fieldbus cable.

Yamatake recommends type A as the fieldbus cable to use.

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.

Type Cable description Size Maximum length

A Shielded, twisted pair

#18 AWG (0.8 mm2)

1900m (6232 ft.)

Structure: twisted pair cable with overall shield

Detailed specifications of the Type A cable at 25°C are as follows;

a) Characteristic impedance: Z0 at 31.25 kHz = 100 ohm +/- 20%

b) Maximum attenuation at 39 kHz = 3.0 db/m

c) Maximum capacitive unbalance to shield = 2 nF/km

d) Maximum DC resistance (per conductor) = 22 ohm/km

e) Maximum propagation delay change 7.8 kHz to 39 kHz = 1.7 us/km

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.

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 HMU303 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.

3-4 : 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.

(1) Verify that the current time is correct in the [HGC time adjusting] box. [Current]

means the present time, which is being transmitted from the model HGC303.

(2) One measurement data will be used as calibration data. (not average data)

Therefore, set the enough hold time.

(3) Auto calibration will start on the day after the setting date.

(4) Model HGC303 holds the process variables to host control system during [Hold

time].

The model HGC303 discerns whether a new calibration should be performed or not by
using an RF (response factor) during auto calibration.

3-42 Model HGC303 - Heat Value Gas Chromatograph

Yamatake Corporation Operation

RF (Response Factor)

An RF is a correction factor used to discern whether a new calibration is correct as
compared with last valid calibration. (For each component)

The model HGC303 uses peak height for RF calculation.

Equation:

PH

RF

n

Where:

= Response factor for component “n“

RF

n

= Peak height of component “n” in calibration gas.

PH

n

= Gas concentration (Unit: mole%) of component “n” in calibration gas.

Cal

n

RF% DEV (Response Factor Percent Devitation)

------------=

Cal

n

n

RF% DEV is calculated by using the following equation.

RF

new

RF% DEV =

% DEV RF Limit

The model HGC303 automatically calculates a “RF% DEV” and decides whether the
value is smaller than the “% DEV RF Limit” or not.

|RF% DEV| ≤ “%DEV RF Limit” => “OK“
|RF% DEV| > “%DEV RF Limit” => “NG“

If all calculation are “OK“, the checked components are calibrated and the new RF is
used as the response factor.

If a NG message appears, none of the components are calibrated and the previous RF
will be used as the response factor.

The user can manually change the “% DEV RF Limit” in Configuration mode.
