This chapter provides important information on how to handle the indicator. Read this carefully before using the indicator.

FVX110 Fieldbus Segment Indicator thoroughly tested at the factory before shipment. When taking delivery of an instrument, visually check them to make sure that no damage occurred during shipment.

Also check that all indicator mounting hardware shown in gure 2.1 is included. If the indicator is ordered without the mounting bracket the indicator mounting hardware will not be included. After checking the indicator, carefully repack it in its box and keep it there until you are ready to install it.

2.2 Unpacking

Keep the indicator in its original packaging to prevent it from being damaged during shipment. Do not unpack the indicator until it reaches the installation site.

2.3 Storage

The following precautions must be observed when storing the instrument, especially for a long period.

(a) Select a storage area which meets the following

conditions:

• It is not exposed to rain or subject to water seepage/leaks.

• Vibration and shock are kept to a minimum.

• It has an ambient temperature and relative humidity within the following ranges.

Storage ambient temperature: –30 to 80°C Relative humidity: 0% to 100% R.H. Preferred temperature and humidity: approx. 25°C and 65% R.H.

(b) When storing the indicator, repack it carefully

in the packaging that it was originally shipped with.

2.4 Selecting the Installation Location

The indicator is designed to withstand severe environmental conditions. However, to ensure that it will provide years of stable and accurate performance, take the following precautions when selecting the installation location.

(a) Ambient Temperature

Avoid locations subject to wide temperature variations or a signicant temperature gradient. If the location is exposed to radiant heat from plant equipment, provide adequate thermal insulation and/or ventilation.

(b) Ambient Atmosphere

Do not install the indicator in a corrosive atmosphere. If this cannot be avoided, there must be adequate ventilation as well as measures to prevent the leaking of rain water and the presence of standing water in the conduits.

IM 01S01C01-01EN

<2. Handling Cautions>

2-2

Although the indicator is designed to be relatively resistant to shock and vibration, an installation site should be selected where this is kept to a minimum.

(d) Installation of Explosion-protected Indicators

An explosion-protected indicators is certied for installation in a hazardous area containing specic gas types. See subsection 2.8 “Installation of an Explosion-Protected Indicators.”

2.5 Waterproong of Cable Conduit Connections

Apply a non-hardening sealant to the threads to waterproof the indicator cable conduit connections. (See gure 5.2, 5.3 and 5.4.)

2.6 Restrictions on Use of Radio Transceivers

IMPORTANT

Although the indicator has been designed to resist high frequency electrical noise, if a radio transceiver is used near the indicator or its external wiring, the indicator may be affected by high frequency noise pickup. To test this, start out from a distance of several meters and slowly approach the indicator with the transceiver while observing the measurement loop for noise effects. Thereafter use the transceiver outside the range where the noise effects were rst observed.

2.7 Insulation Resistance and Dielectric Strength Test

Since the indicator has undergone insulation resistance and dielectric strength tests at the factory before shipment, normally these tests are not required. If the need arises to conduct these tests, heed the following:

(a) Do not perform such tests more frequently than

is absolutely necessary. Even test voltages that do not cause visible damage to the insulation may degrade the insulation and reduce safety margins.

(b) Never apply a voltage exceeding 500 V DC

(100 V DC with an internal lightning protector) for the insulation resistance test, nor a voltage exceeding 500 V AC (100 V AC with an internal lightning protector) for the dielectric strength test.

signal lines from the indicator terminals. The procedure for conducting these tests is as follows:

• Insulation Resistance Test

1) Short-circuit the + and – SUPPLY terminals in the terminal box.

2) Turn OFF the insulation tester. Then connect the insulation tester plus (+) lead wire to the shorted SUPPLY terminals and the minus (–) leadwire to the grounding terminal.

3) Turn ON the insulation tester power and measure the insulation resistance. The voltage should be applied as briey as possible to verify that the insulation resistance is at least 20 MΩ.

4) After completing the test and being very careful not to touch exposed conductors disconnect the insulation tester and connect a 100 kΩ resistor between the grounding terminal and the shortcircuiting SUPPLY terminals. Leave this resistor connected at least one second to discharge any static potential. Do not touch the terminals while it is discharging.

• Dielectric Strength Test

1) Short-circuit the + and – SUPPLY terminals in the terminal box.

2) Turn OFF the dielectric strength tester. Then connect the tester between the shorted SUPPLY terminals and the grounding terminal. Be sure to connect the grounding lead of the dielectric strength tester to the ground terminal.

3) Set the current limit on the dielectric strength tester to 10 mA, then turn ON the power and gradually increase the test voltage from ‘0’ to the specied voltage.

4) When the specied voltage is reached, hold it for one minute.

5) After completing this test, slowly decrease the voltage to avoid any voltage surges.

Note: In the rating 1, the output current of the barrier must

be limited by a resistor “Ra” such that Io=Uo/Ra. In the rating 2 or 3, the output characteristics of the barrier must be the type of trapezoid which are certied as the FISCO model (See “FISCO Rules”). The safety barrier may include a terminator. More than one eld instruments may be connected to the power supply line.

● FISCO Rules

The FISCO Concept allows the interconnection of intrinsincally safe apparatus to associated apparatus not specically examined in such combination. The criterion for such interconnection is that the voltage (Ui), the current (Ii) and the power (Pi) which intrinsically safe apparatus can receive and remain intrinsically safe, considering faults, must be equal or greater than the voltage (Uo, Voc, Vt), the current (Io, Isc, It) and the power (Po) which can be provided by the associated apparatus (supply unit).

Po ≤ Pi, Uo ≤ Ui, Io ≤ Ii

In addition, the maximum unprotected residual capacitance (Ci) and inductance (Li) of each apparatus (other than the terminators) connected to the eldbus must be less than or equal to 5 nF and 10 µH respectively.

Ci ≤ 5nF, Li ≤ 10µH

In each I.S. eldbus segment only one active source, normally the associated apparatus, is allowed to provide the necessary power for the eldbus system. The allowed voltage(Uo, Voc,Vt) of the associated apparatus used to supply the bus cable must be limited to the range of 14 V dc to 17.5 V dc. All other equipment connected to the bus cable has to be passive, meaning that the apparatus is not allowed to provide energy to the system, except to a leakage current of 50 µA for each connected device.

Supply unit

Trapezoidal or rectangular output characteristic only

Uo = 14...17.5 V (I.S. maximum value)

Io according to spark test result or other

assessment. No specication of Lo and Co is required on the certicate or label.

Cable

The cable used to interconnect the devices needs to comply with the following parameters:

Loop resistance R': 15...150 Ω/km Inductance per unit length L': 0.4...1 mH/km Capacitance per unit length C': 45...200 nF/km. C'=C' line/line + 0.5 C' line/screen, if both lines are oating or C'=C' line/line + C' line/screen, if the screen is connected to one line. Length of spur cable: max. 60 m Length of trunk cable: max. 1 km (Group IIC) or 5 km (Group IIB) Length of splice: max.1m

Terminators

At each end of the trunk cable an FM approved line terminator with the following parameters is suitable:

R = 90...100 Ω C = 0...2.2 mF

System evaluations

The number of passive device like transmitters, actuators, hand held terminals connected to a single bus segment is not limited due to I.S. reasons. Furthermore, if the above rules are respected, the inductance and capacitance of the cable need not to be considered and will not impair the intrinsic safety of the installation.

● FNICO Rules

The FNICO Concept allows the interconnection of nonincendive eld wiring apparatus to associated nonincendive eld wiring apparatus not specically examined in such combination. The criterion for such interconnection is that the voltage (Vmax), the current (Imax) and the power (Pmax) which nonincendive eld wiring apparatus can receive and remain nonincendive, considering faults, must be equal or greater than the voltage (Uo, Voc or Vt), the current (Io, Isc or It) and the power (Po) which can be provided by the associated nonincendive eld wiring apparatus (supply unit). In addition the maximum unprotected residual capacitance (Ci) and inductance (Li) of each apparatus (other than terminators) connected to the Fieldbus must be less than or equal to 5nF and 20uH respectively.

In each N.I. Fieldbus segment only one active source, normally the associated nonincendive eld wiring apparatus, is allowed to provide the necessary power for the Fieldbus system. The allowed voltage (Uo, Voc or Vt) of the associated nonincendive eld wiring apparatus used to supply the bus cable must be limited to the range 14Vdc to 17.5Vdc. All other equipment connected to the bus cable has to be passive, meaning that the apparatus is not allowed to provide energy to the system, except a leakage current of 50 µA for each connected device. Separately powered equipment needs galvanic isolation to ensure the nonincendive eld wiring Fieldbus circuit remains passive.

4.1 Outline

Fieldbus is a widely used bi-directional digital communication protocol for eld devices that enable the simultaneous output to many types of data to the process control system.

FVX110 Fieldbus Segment Indicatior employs the specication standardized by The Fieldbus Foundation, and provides interoperability between Yokogawa devices and those produced by other manufacturers.

For information on other features, engineering, design, construction work, startup and maintenance of Fieldbus, refer to “Fieldbus Technical Information” (TI 38K03A01-01E).

4.2 Internal Structure of FVX110

The FVX110 contains two virtual eld devices (VFD) that share the following functions.

4.2.1 System/network Management VFD

• Sets node addresses and Physical Device tags (PD Tag) necessary for communication.

• Controls the execution of function blocks.

• Manages operation parameters and communication resources (Virtual Communication Relationship: VCR).

4.2.2 Function Block VFD

(1) Resource block

• Manages the status of FVX110 hardware.

• Automatically informs the host of any detected faults or other problems.

(2) LCD Transducer block

• Controls the display of the integral indicator.

(3) MAO function block

• Transfers 8 analog variables of the IO subsystem to transducer block using 8 input parameters (IN_1 to IN_8).

(4) PID function block

• Performs the PID control computation based on the deviation of the measured value from the setpoint.

(5) SC function block

• Uses the line-segment function to convert input signal values.

(6) IT function block

• Integrates input signal values.

(7) IS function block

• Same as MAO function block, this block transfer 8 analog variables (IN_1 to IN_8) to transducer block.

• Provides a function for automatic selection of one signal from multiple input signals using a specied method of selection.

5.3 Wiring

5.3.1 Wiring Precautions

IMPORTANT

• Lay wiring as far as possible from electrical noise sources such as large capacity transformers, motors, and power supplies.

• Remove the electrical connection dust cap before wiring.

• All threaded parts must be treated with waterproong sealant. (A non-hardening silicone group sealant is recommended.)

• To prevent noise pickup, do not pass signal and power cables through the same ducts.

• Explosion-protected instruments must be wired in accordance with specic requirements (and, in certain countries, legal regulations) in order to preserve the effectiveness of their explosion-protected features.

• The terminal box cover is locked by an Allen head bolt (a shrouding bolt) on ATEX ameproof type indicators. When the shrouding bolt is driven clockwise using an Allen wrench, it goes in. The cover lock can then be released and the cover can be opened by hand. See subsection 10.2 “Disassembly and Reassembly” for details.

• Plug and seal an unused conduit connection.

5.3.2 Wiring Installation

(1) General-use Type and Intrinsically Safe

Type

With the cable wiring, use a metallic conduit or waterproof glands.

• Apply a non-hardening sealant to the terminal box connection port and to the threads on the exible metal conduit for waterproong.

5.5 Connection of Devices

The following are required for use with Fieldbus devices:

• Power supply:

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.

• Terminator:

Fieldbus requires two terminators. Refer to the supplier for details of terminators that are attached to the host.

• Field devices:

Connect Fieldbus communication type eld devices. Two or more EJX, YTA, AXF or other devices can be connected.

• Host:

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, refer to the instruction manual for each host. No other details on the host are given in this manual.

• Cable:

Used for connecting devices. Refer to “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 FVX110, use an M4 screw terminal claw. Some hosts require a connector.
