<11. COMMUNICATION (FIELDBUS)> 54 11. COMMUNICATION (FIELDBUS)
Fieldbusisfullydependentupondigital communication protocol and differs in operation from conventional 4 to 20 mA transmission
and the BRAIN communication protocol. It is recommended that novice users use eldbus devices in accordance with the procedures described in this section. The procedures assume that eldbus devices will be set up on a bench or in an instrument shop.
11.1 Ampli erforFieldbus
Communication Type
Read IM 01F06A00-01EN for the details of the amplifier. This section encompasses topics applicable to only the Fieldbus communication type.
(1) TheFieldbuscommunicationtypehasnolocal key access function.
(2) TheFieldbuscommunicationtypehasno BT200(BRAINTERMINAL)connectionpin.
(3) TheFieldbuscommunicationtypehasa simulation function. The SIMULATE_ENABLE switch is mounted on the ampli er. Read Section 11.6 “Simulation Function” for details of the simulation function.
• Terminator:
Fieldbus requires two terminators. Read the supplier for details of terminators that are attached to the host.
• Fielddevices:
Connect your Fieldbus communication type digitalYEWFLO to a eldbus. Two or more digitalYEWFLOs and other eld devices can be connected. For the terminal assignment on the digitalYEWFLO, read Table 11.1.

11.2 ConnectionofDevices
The following instruments are required for use with Fieldbus devices:
• Powersupply:
Fieldbus requires a dedicated power supply. It is recommended that current capacity be well over the total value of the maximum current consumed by all devices (including the host). Conventional DC current cannot be used as is.
Used for accessing eld devices. A
dedicated host (such as DCS) is used for
an instrumentation line while dedicated communication tools are used for experimental purposes. For operation of the host, read the instruction manual for each host. No other details on the host are given in this manual.
• Cable:
Used for connecting devices. Read “Fieldbus Technical Information” (TI 38K03A01-01E) for details of instrumentation cabling. For laboratory or other experimental use, a twisted pair cable two to three meters in length with a cross section of 0.9 mm2 or more and a cycle period of within 5 cm (2 inches) may be used. Termination processing depends on the type of device being deployed. For the digitalYEWFLO, use terminal lugs applicable to M4 screw terminals. Some hosts require a connector.
Read Yokogawa when making arrangements to purchase the recommended equipment. Connect the devices as shown in Figure 11.2. Connect the terminators at both ends of the trunk, with a minimum length of the spur laid for connection.
The polarity of signal and power must be maintained.

11.5 GenerationofAlarm 11.5.1 Indication of Alarm
When the self-diagnostics function indicates that a device is faulty, an alarm (device alarm) is issued from the resource block. When an error (block error) is detected in each function block or an error in the process value (process alarm) is detected, an alarm is issued from each block. If an LCD indicator is installed, the error number is displayed as AL- XX. If two or more alarms are issued, multiple error numbers are displayed in 2-second intervals. (when “1” is set to DISPLAY_CYCLE).

Figure 11.5 Error Identi cation on Indicator
The error details corresponding to alarm indications on the LCD indicator and whether or not switches are provided to disable the corresponding alarms are shown in Table 11.3. For the alarms for which an alarm mask switch is provided, the default alarm settings are also shown. Those alarms for which
an alarm mask switch is not provided are enabled at all times. For how to modify these mask switch statuses, read IM 01F06F00-01EN APPENDIX

<11. COMMUNICATION (FIELDBUS)> 58 11.6 SimulationFunction
The simulation function simulates the input of a function block and lets it operate as if the data was received from the transducer block. It is possible to conduct testing for the downstream function blocks or alarm processes.
A SIMULATE_ENABLE jumper switch is mounted on the digitalYEWFLO’s ampli er. This is to prevent the accidental operation of this function. When
this is switched on, simulation is enabled. (Read Figure 11.4.) To initiate the same action from a remote terminal, if REMOTE LOOP TEST SWITCH is written to SIM_ENABLE_MSG (index 1044) parameter of the resource block, the resulting action is the same as is taken when the above switch is on. Note that this parameter value is lost when the power is turned off. In simulation enabled status,
an alarm is generated from the resource block, and other device alarms will be masked; for this reason the simulation must be disabled immediately after using this function.
The SIMULATE parameter of AI block consists of the elements listed in Table 11.5 below.

• Intrinsically Safe Ex ic
Applicable Standard: EN60079-0: 2009/EN60079- 0:2012
Special conditions for safe use
1. For process temperatures above 250°C the ow meters of the /HT version must be used.
2. Because the enclosures of the ow meters
and the ow converter are made of aluminium alloy, when used in an potentially explosive atmosphere requiring apparatus of equipment categoly 1 G, they must be installed so, that even in the event of rare incidents, an ignition source due to impact of friction between the enclosure and iron/steel is excluded.
• Precautions shall be taken to minimize the risk from electrostatic discharge of painted parts.
• The dielectric strength of at least 500 V a.c. r.m.s. between the intrinsically safe circuits and the enclosure of the ow meter or the converter is limited only by the overvoltage protection.
 Installation WARNING
• All wiring shall comply with local installation requirements and local electrical code.
• Use the suitable heat-resisting cables (over 90°C) for the digitalYEWFLO Series Vortex Flowmeter when the ambient temperature exceeds 60°C and/or the process temperature exceeds 200°C.
• For ameproof; Cable glands, adapters and/ or blanking elements shall be of Ex “d” for Ex “d” installations. They shall be installed so as to maintain the speci ed degree of protection (IP Code) of the owmeter.
• For ATEX intrinsically safe Ex ic; Cable glands, adapter and / or blanking elements shall be of Ex “n”, Ex “e”, or Ex “d” and shall be installed so as to maintain the speci ed degree of protection (IP Code) of the equipment.

<INSTALLATION AND OPERATING PRECAUTIONS FOR TIIS FLAMEPROOF EQUIPMENT> 70
INSTALLATION AND OPERATING PRECAUTIONS FOR TIIS FLAMEPROOF EQUIPMENT
Apparatus Certi ed Under Technical Criteria (IEC-compatible Standards)
1. General
The following describes precautions on electrical apparatus of ameproof construction (hereinafter referred to as ameproof apparatus) in explosion- protected apparatus.
Following the Labour Safety and Health Laws
of Japan, ameproof apparatus is subjected to
type tests to meet either the technical criteria for explosionproof electrical machinery and equipment (standards noti cation no. 556 from the Japanese Ministry of Labour) (hereinafter referred to as technical criteria), in conformity with the IEC Standards, or the “Recommended Practice for Explosion-Protected Electrical Installations in General Industries,” published in 1979. These certi ed apparatus can be used in hazardous locations where explosive or in ammable gases or vapours may be present.
Certi ed apparatus includes a certi cation label and an equipment nameplate with the speci cations necessary for explosion requirements as well as precautions on explosion protection. Please con rm these precautionary items and use them to meet speci cation requirements.
For electrical wiring and maintenance servicing, please read “Internal Wiring Rules” in the Electrical Installation Technical Standards as well as “USER’S GUIDELINES for Electrical Installations for Explosive Gas Atmospheres in General Industry,” published in 1994.
To meet ameproof requirements, equipment that can be termed “ ameproof” must:
(1) Becerti edbyaJapanesepublicauthorityin
accordance with the Labour Safety and Health Laws of Japan and have a certi cation label in an appropriate location on its case, and
(2) Beusedincompliancewiththespeci cations marked on its certi cation label, equipment name plate and precautionary information furnished.
2. Electrical Apparatus of Flameproof Type of Explosion-Protected Construction
Electrical apparatus which is of ameproof construction is subjected to a type test and certi ed by the Japanese Ministry of Labour aiming at preventing explosion caused by electrical apparatus in a factory or any location where in ammable gases or vapours may be present. The ameproof construction is of completely enclosed type and
its enclosure shall endure explosive pressures in cases where explosive gases or vapours entering the enclosure cause explosion. In addition, the enclosure construction shall be such that ame caused by explosion does not ignite gases or vapours outside the enclosure.
In this manual, the word " ameproof" is applied
to the ameproof equipment combined with the types of protection "e", "o", "i", and "d" as well as ameproof equipment.
3. Terminology (1) Enclosure
An outer shell of an electrical apparatus, which encloses live parts and thus is needed to con gure explosion-protected construction.
(2) Shroud
A component part which is so designed that the fastening of joint surfaces cannot be loosened unless a special tool is used.
(3) Enclosure internal volume
This is indicated by:— the total internal volume of the ameproof enclosure minus the volume of the internal components essential to equipment functions.
(4) Path length of joint surface
On a joint surface, the length of the shortest path through which ame ows from the inside to outside of the ameproof enclosure. This de nition cannot be applied to threaded joints.
IM 01F06A01-01EN


<INSTALLATION AND OPERATING PRECAUTIONS FOR TIIS FLAMEPROOF EQUIPMENT> 71
(5) Gaps between joint surfaces
The physical distance between two mating surfaces, or differences in diameters if the mating surfaces are cylindrical.
Note: Thepermissiblesizesofgapsbetweenjointsurfaces,
the path length of a joint surface and the number of joint threads are determined by such factors as the enclosure’s internal volume, joint and mating surface construction, and the explosion classi cation of the speci ed gases and vapours.
4. Installation of Flameproof Apparatus (1) Installation Area
Flameproof apparatus may be installed, in accordance with applicable gases, in a hazardous area in Zone 1 or 2, where the speci ed gases are present. Those apparatus shall not be installed in a hazardous area in Zone 0.
5. External Wiring for Flameproof Apparatus
Flameproof apparatus require cable wiring for their electrical connections. For cable wiring, cable glands (cable entry devices for ameproof type)
to wiring connections shall be attached. All non- live metal parts such as the enclosure shall be securely grounded. For details, read the “USER’S GUIDELINES for Electrical Installations for Explosive Gas Atmospheres in General Industry,” published in 1994.
(1) Cable Wiring
• For cable wiring, cable glands (cable entry devices for ameproof type) speci ed or supplied with the apparatus shall be directly attached to the wiring connections to complete sealing of the apparatus.
• Screws that connect cable glands to the apparatus are those for G-type parallel pipe threads (JIS B 0202) with no sealing property. To protect the apparatus from corrosive gases or moisture, apply nonhardening sealant
such as liquid gaskets to those threads for
waterproo ng.
• Speci c cables shall be used as recommended
by the “USER’S GUIDELINES for Electrical Installations for Explosive Gas Atmospheres in General Industry,” published in 1994.
• In necessary, appropriate protective pipes (conduit or exible pipes), ducts or trays shall be used for preventing the cable run (outside the cable glands) from damage.
• To prevent explosive atmosphere from being propagated form Zone 1 or 2 hazardous location to any different location or non- hazardous location through the protective pipe or duct, apply sealing of the protective pipes in the vicinity of individual boundaries, or ll the ducts with sand appropriately.
• When branch connections of cables is made, a ameproof or increased-safety connection box shall be used. In this case, ameproof or increased-safety cable glands meeting the type of connection box must be used for cable connections to the box.
Note: Hazardousareasareclassi edinzonesbasedupon the frequency of the appearance and the duration of an explosive gas atmosphere as follows:
Zone 0: An area in which an explosive gas atmosphere
is present continuously or is present for long
periods.
Zone 1: An area in which an explosive gas atmosphere
likely to occur in normal operation.
Zone 2: An area in which an explosive gas atmosphere is not likely to occur in normal operation and if it
does occur it will exist for a short period only.
(2) Environmental Conditions
is
The standard environmental condition for the installation of ameproof apparatus is limited to
an ambient temperature range from –20°C to +40°C (for products certi ed under Technical Criteria). However, some eld-mounted instruments may be certi ed at an ambient temperature up to +60°C as indicated on the instrument name plates. If the ameproof apparatus are exposed to direct sunshine or radiant heat
from plant facilities, appropriate thermal protection measures shall be taken.
IM 01F06A01-01EN


<INSTALLATION AND OPERATING PRECAUTIONS FOR TIIS FLAMEPROOF EQUIPMENT> 72
6. Maintenance of Flameproof Apparatus
To maintain the ameproof apparatus, do
the following. (For details, read Chapter 10 “MAINTENANCE OF EXPLOSION-PROTECTED ELECTRICAL INSTALLATION” in the USER’S GUIDELINES for Electrical Installations for Explosive Gas Atmospheres in General Industry.)
(1) Maintenance servicing with the power on.
Flameproof apparatus shall not be maintenance- serviced with its power turned on. However, in cases where maintenance servicing is to be conducted with the power turned on, with the equipment cover removed, always use a gas detector to check that there is no explosive gas
in that location. If it cannot be checked whether
an explosive gas is present or not, maintenance servicing shall be limited to the following two items: (a) Visualinspection
Visually inspect the ameproof apparatus, metal conduits, and cables for damage or corrosion, and other mechanical and structural defects.
(b) Zeroandspanadjustments
These adjustments should be made only to the extent that they can be conducted from the outside without opening the equipment cover. In doing this, great care must be taken not to cause mechanical sparks with tools.
(2) Repair
If the ameproof apparatus requires repair, turn off the power and transport it to a safety (non- hazardous) location. Observe the following points before attempting to repair the apparatus.
(a) Makeonlysuchelectricalandmechanical repairs as will restore the apparatus to
its original condition. For the ameproof apparatus, the gaps and path lengths of joints and mating surfaces, and mechanical strength of enclosures are critical factors in explosion protection. Exercise great care not to damage the joints or shock the enclosure.
(b) Ifanydamageoccursinthreads,joints
or mating surfaces, inspection windows, connections between the sensor and terminal box, shrouds or clamps, or external wiring connections which are essential in ameproofness, contact Yokogawa Electric Corporation.
CAUTION
Do not attempt to re-process threaded connections or re nish joints or mating surfaces.
(c) Unlessotherwisespeci ed,theelectrical circuitry and internal mechanisms may be repaired by component replacement, as this will not directly affect the requirements for ameproof apparatus (however, bear in mind that the apparatus must always be restored to its original condition). If you attempt to repair the ameproof apparatus, company-speci ed components shall be used.
(d) Beforestartingtoservicetheapparatus,be sure to check all parts necessary for retaining the requirements for ameproof apparatus. For this, check that all screws, bolts, nuts, and threaded connections have properly been tightened.
(3) Prohibition of speci cation changes and modi cations
Do not attempt to change speci cations or make modi cations involving addition of or changes in external wiring connections.
7. Selection of Cable Entry Devices for Flameproof Type
IMPORTANT
The cable glands (cable entry devices for ameproof type) conforming to IEC Standards are certi ed in combination with the ameproof apparatus. So, Yokogawa-speci ed cable entry devices for ameproof type shall be used to meet this demand.
