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 water.

• It suffers minimum vibration and shock.

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

Ambient temperature:

–40 to 85°C without integral indicator –30 to 80°C with integral indicator

Relative humidity:

5% to 100% R.H. (at 40°C)

Preferred temperature and humidity:

approx. 25°C and 65% R.H.

(b) When storing the transmitter, repack it as nearly as

possible to the way it was packed when delivered from the factory.

oughly clean the chambers inside the cover flanges and integral flow orifice unit, so that no measured fluid remains in it. Also make sure before storing that the pressure-detector and transmitter section are securely mounted.

2-1

IM 01C22K01-01E

2. HANDLING CAUTIONS

2.4 Selecting the Installation Location

The transmitter is designed to withstand severe environmental conditions. However, to ensure stable and accurate operation for years, observe the following precautions when selecting an installation location.

(a) Ambient Temperature

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

(b) Ambient Atmosphere

Avoid installing the transmitter in a corrosive atmosphere. If the transmitter must be installed in a corrosive atmosphere, there must be adequate ventilation as well as measures to prevent intrusion or stagnation of rain water in conduits.

Select an installation site suffering minimum shock and vibration (although the transmitter is designed to be relatively resistant to shock and vibration).

(d) Installation of Explosion-protected Transmitters

Explosion-protected transmitters can be installed in hazardous areas according to the types of gases for which they are certified. See Subsection 2.9 “Installation of Explosion Protected Type Transmitters.”

2.5 Pressure Connection

WARNING

• Instrument installed in the process is under pressure. Never loosen the process connector bolts to avoid the dangerous spouting of process fluid.

The following precautions must be observed in order to safely operate the transmitter under pressure.

(a) Make sure that the four manifold bolts are tightened

firmly.

(b) Make sure that there are no leaks in the impulse

piping.

maximum working pressure.

2.6 Waterproofing of Cable Conduit Connections

Apply a non-hardening sealant to the threads to waterproof the transmitter cable conduit connections. (See Figure 6.4.2a, 6.4.2b and 6.4.2d.)

2.7 Restrictions on Use of Radio Transceiver

IMPORTANT

Although the transmitter has been designed to resist high frequency electrical noise, if a radio transceiver is used near the transmitter or its external wiring, the transmitter may be affected by high frequency noise pickup. To test for such effects, bring the transceiver in use slowly from a distance of several meters from the transmitter, and observe the measurement loop for noise effects. Thereafter, always use the transceiver outside the area affected by noise.

2.8 Insulation Resistance and Dielectric Strength Test

Since the transmitter has undergone insulation resistance and dielectric strength tests at the factory before shipment, normally these tests are not required. However, if required, observe the following precautions in the test procedures.

(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.

lines from the transmitter terminals. Perform the tests in the following procedure:

• 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.

2-2

IM 01C22K01-01E

2. HANDLING CAUTIONS

3) Turn ON the insulation tester power and measure the insulation resistance. The voltage should be applied short 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 specified voltage.

4) When the specified voltage is reached, hold it for one minute.

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

2.9 Installation of Explosion

Protected Type

In this section, further requirements and differences and for explosionproof type instrument are described. For explosionproof type instrument, the description in this chapter is prior to other description in this users manual.

4.4 Changing the Direction of Integral Indicator

IMPORTANT

Always turn OFF power, release pressure and remove a transmitter to non-hazardous area before disassembling and reassmbling an indicator.

An integral indicator can be installed in the following three directions. Follow the instructions in section 9.4 for removing and attaching the integral indicator.

5. INSTALLING IMPULSE PIPING

5.1 Process Piping Installation Precautions

The manifold contains a small-bore orifice. For the transmitter of a high pressure connection right side, the orifice is placed facing such a direction as to enable normal flow measurement when fluid is flowed from right to left (as viewed from the front). If the orifice is removed from the manifold, it must be replaced facing the correct direction. (For disassembly and reassembly procedures, see Subsection 9.4.4)

Pay careful attention to the following points when routing the process piping and connection the process piping to the transmitter.

5.1.1 Connecting Process Piping to the

Transmitter

(1) Confirming the Process Fluid Flow Direc-

tion (Figure 5.1.1)

The mark “ ” on the manifold indicates the direction in which the process fluid is flowed (from right to left). When connecting the process piping to the process connector, confirm the process fluid flow direction.

Manifold

(2) Tightening the Process Connector Mount-

ing Bolts

The transmitter is shipped with the process connector mounting bolts only loosely tightened. After connecting the process piping, tighten these bolts uniformly to prevent leaks with a torque of 39 to 49 N·m {4 to 5 kgf·m}.

(3) Removing the Process Connector Port

Dustproof Cap

The process connector port threads are covered with a plastic cap to exclude dust. This cap must be removed before connecting the piping. (Be careful not to damage the threads when removing this cap. Never insert a screwdriver or other tool between the cap and port threads to remove the cap.)

5.1.2 Routing the Process Piping

(1) Relationship between Process Fluid and

Manifold Locations (For the vertical impulse piping type)

If condensate (or gas) generated in the process piping were allowed to accumulate, then it would be necessary to remove it periodically by opening the drain (or vent) plug. However, this would generate a transient disturbance in the pressure measurement. Therefore, the process piping must be routed so that any condensate (or gas) generated in the process piping will not accumulate in the pressure-sensing assembly of the transmitter.

Bolt

Process connector (low pressure side)

NOTE

• If the process fluid is a gas, then as a rule the manifold must be located at the downside of the pressure-sensing assembly. (Figure 5.1.2)

• If the process fluid is a liquid, then as a rule the manifold must be located at the upside of the pressure-sensing assembly. (Figure 5.1.3)

IM 01C22K01-01E

5. INSTALLING IMPULSE PIPING

(2) Pipe Size for Process Piping

Use a 15 mm (1/2-inch) pipe for process piping connection to the process connector.

(3) Preventing Freezing

If there is any risk that the process fluid in the transmitter pressure-sensing assembly could freeze or solidify, use a steam jacket or heater to maintain the temperature of the fluid.

6. WIRING

6.1 Wiring Precautions

IMPORTANT

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

• Remove electrical connection dust cap before wiring.

• All threaded parts must be treated with waterproofing 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 specific requirements (and, in certain countries, legal regulations) in order to preserve the effectiveness of their explosionprotected features.

• The terminal box cover is locked by an Allen head bolt (a shrouding bolt) on CENELEC, IECEx, and TIIS flameproof type transmitters. When the shrouding bolt is driven clockwise by an Allen wrench, it is going in and cover lock is released, and then the cover can be opened. See Subsection 9.4 “Disassembly and Reassembly” for details.

Refer to The “Installation and Operating Precautions for TIIS Flameproof Equipment” and “Installation and Operating Precautions for TIIS Intrinsically Safe Equipment” at the end of this manual for correct wiring.

CAUTION

When selecting cables for TIIS flameproof type transmitters, determine cables' maximum allowable heat resistance depending on the temperature condition on the transmitter. See Section

2.9.5 TIIS Certification for details.

(d) In environment where oils, solvents, corrosive gases

or liquids may be present, use wires or cables that are resistant to such substances.

(e) It is recommended that crimp-on solderless terminal

lugs (for 4 mm screws) with insulating sleeves be used for leadwire ends.

7. OPERATION

7.1 Preparation for Starting Operation

The Model EJA115 low flow transmitter measures the flow rates of liquids and gases. This section describes the operation procedure for the EJA115 as shown in Figure 7.1 (vertical impulse piping type, high-pressure connection: right side) when measuring a liquid flow rate.

(a) Follow the procedures below to introduce process

pressure into the transmitter.

1) Open the stop valve on the downstream side.

2) Gradually open the stop valve on the upstream side

to introduce process fluid into the transmitter pressure-detector section. This will cause process fluid to flow into the orifice built in the manifold, and apply flow-dependent differential pressure to the high and low pressure sides of the transmitter.

3) Confirm that there are no pressure leaks in the stop

valves on the upstream and downstream sides, process piping connection or transmitter, etc.

(b) Venting Gas from the Transmitter Pressure-detector

Section Since the piping in the example of Figure 7.1 is constructed to be self-venting, no venting operation is required. If it is not possible to make the piping self-venting, refer to Subsection 7.6 for instructions.

Open the terminal box cover, and connect the BT200 to the SUPPLY + and – terminals.

(d) Using the BT200, confirm that the transmitter is

operating properly. Check parameter values or change the setpoints as necessary. See Chapter 8 for BT200 operation. If the transmitter is equipped with an integral indicator, its indication can be used to confirm that the transmitter is operating properly.

7.3 Starting Operation

After completing the zero point adjustment, follow the procedure below to start operation.

1) Open the stop valve on the upstream side.

2) Gradually open the stop valve on the downstream

side. This places the transmitter in an operational condition.

3) Confirm the operating status. If the output signal

exhibits wide fluctuations (hunting) due to periodic variation in the process pressure, use BT200 to dampen the transmitter output signal. Confirm the hunting using a receiving instrument or the integral indicator, and set the optimum damping time constant. See Subsection 8.3.3 (3), “Damping Time Constant Setup.”

4) After confirming the operating status, perform the

following.

IMPORTANT

• Remove the BT200 from the terminal box, and confirm that none of the terminal screws are loosened.

• Close the terminal box cover and the amplifier cover. Screw each cover in tightly until it will not turn further.

• Two covers are required to be locked on the CENELEC, IECEx, and TIIS Flameproof type transmitters. An Allen head bolts (shrouding bolts) are provided under edge of the each cover for locking. When a shrouding bolts are driven counterclockwise by an Allen wrench, it is coming out and locks up a cover. (See page 9-3) After locking, the covers should be confirmed not to be opened.

• Tighten the zero-adjustment cover mounting screw to fix the cover in position.

7.4 Shutting Down Operation

Shut down the transmitter operation as follows.

1) Turn off the power.

2) Close the stop valves on the up and downstream sides.

NOTE

Whenever shutting down the transmitter for a long period, remove any process fluid from the transmitter pressure-detector section.

7. OPERATION

7.6 Venting or Draining Transmitter Pressure-detector Section

Since this transmitter is designed to be self-draining and self-venting with vertical impulse piping connections, neither draining nor venting will be required if the impulse piping is configured appropriately for selfdraining or self-venting operation.

If condensate (or gas) collects in the transmitter pressure-detector section, the measured pressure may be in error. If it is not possible to configure the piping for self-draining (or self-venting) operation, you will need to loosen the drain (vent) screw on the transmitter to completely drain (vent) any stagnated liquid (gas).

However, since draining condensate or bleeding off gas gives the pressure measurement disturbance, this should not be done when the loop is in operation.

WARNING

Since the accumulated liquid (or gas) may be toxic or otherwise harmful, take appropriate care to avoid contact with the body, or inhalation of vapors.

7.6.2 Venting Gas

1) Gradually open the vent screw to vent gas from the transmitter pressur-detector section. (See Figure

7.6.2.)

2) When the transmitter is completely vented, close the vent screw.

3) Tighen the vent screw to a torque of 10 N·m {1kgf·m}.

7.6.1 Draining Condensate

1) Gradually open the drain screw or drain plug and drain the transmitter pressure-detector section. (See Figure 7.6.1.)

2) When all accumulated liquid is completely removed, close the drain screw or drain plug.

3) Tighten the drain screw to a torque of 10 N·m {1kgf·m}, and the drain plug to a torque of 34 to 39 N·m {3.5 to 4 kgf·m}.

With actual pressure being applied to the transmitter, the range-setting switch (push-button) located on the optional integral indicator plate and the external zeroadjustment screw allow users to change (re-range) the low- and high-limit values for the measurement range (LRV and HRV) without using BT200. However, other changes in the display settings (scale range and engineering unit) for the integral indicator requires BT200.

Follow the procedure below to change the LRV and HRV settings.

[Example]

Rerange LRV to 0 and HRV to 20 kPa.

1) Connect the transmitter and apparatus as shown in Figure 9.3.1 and warm up for at least five minutes.

2) Press the range-setting push-button. The integral indicator then displays “LSET.”

3) Apply a pressure of 0 kPa (atmospheric pressure) to the transmitter.

(Note 1)

4) Turn the external zero-adjustment screw in the desired direction. The integral indicator displays the output signal in %.

(Note 2)

5) Adjust the output signal to 0% (1 V DC) by rotating the external zero-adjustment screw. Doing so completes the LRV setting.

IM 01C22K01-01E

6) Press the range-setting push-button. The integral indicator then displays “HSET.”

7) Apply a pressure of 20 kPa to the transmitter.

(Note 1)

8) Turn the external zero-adjustment screw in the desired direction. The integral indicator displays the output signal in %.

(Note 2)

9) Adjust the output signal to 100% (5 V DC) by rotating the external zero-adjustment screw. Doing so completes the HRV setting.

10) Press the range-setting push-button. The transmitter then switches back to the normal operation mode with the measurement range of 0 to 20 kPa.

Note 1: Wait until the pressure inside the pressure-detector section

has stabilized before proceeding to the next step.

Note 2: If the pressure applied to the transmitter exceeds the previous

LRV (or HRV), the integral indicator may display error number “Er.07” (In this case, the output signal percent and “Er.07” are displayed alternately every two seconds). Although “Er.07” is displayed, you may proceed to the next step. However, should any other error number be displayed, take the appropriate measure in reference to Subsection

8.5.2, “Errors and Countermeasures.”

7. OPERATION

IMPORTANT

• Do not turn off the power to the transmitter immediately after completion of the change in the LRV and/or HRV setting(s). Note that powering off within thirty seconds after setting will cause a return to the previous settings.

• Changing LRV automatically changes HRV to the following value.

HRV = previous HRV + (new LRV – previous LRV)

• If the range-setting push-button and external zero-adjustment screw are not touched during a range-change operation, the transmitter automatically switches back to the normal operation mode.

Note : Use a thin bar which

has a blunt tip, e.g., a hexagonal wrench, to press the rangesetting push-button

Sets the Tag No. (using 16 alphanumeric characters). Note: Up to 8 alphanumerics (upper case letters) can be used in the BT100.

Sets the calibration range for 4 to 20 mA DC. Sets three data items: range unit, input value at 4 mA DC (LRV), and input value at 20 mA DC (HRV).

Note: LRV and HRV can be specified with range value specifications up to 5 digits

(excluding any decimal point) within the range of –32000 to 32000.

Adjusts the output response speed for 4 to 20 mA DC. Can be set in 9 increments from 0.2 to 64 s.

Sets modes for output signal and integral indicator to “Linear mode” (proportional to input differential pressure) or to “Square root mode” (proportional to flow).

Used mainly to stabilize output near 0% if output signal is the square root mode. Two modes are available: forcing output to 0% for input below a specific value, or changing to proportional output for input below a specific value.

Change the range of normal output.

Sets the following 5 types of integral indicator scale ranges and units:

% scale indicator, user set scale indicator, alternate indication of user set scale

and % scale, input pressure display, alternate indication of input pressure and % scale When using the user set scale, 4 types of data can be set: user set scale setting, unit (BT200 only), display value at 4 mA DC (LRV), and display value at 20 mA DC (HRV).

Note: LRV and HRV can be specified with range value specifications up to 5

digits (excluding any decimal point) within the range of –19999 to 19999.

Sets a unit for temperatures displayed on the BT200.

Sets a unit for static pressure displayed on the BT200.

Reverses the direction for 4 to 20 mA DC output relative to input. Reverse mode is used for applications in which safety requires that output be driven toward 20 mA if input is lost.

Displays the status of 4 to 20 mA DC output when a CPU failure. The parameter of the standard unit is fixed to the high limit value.

Sets the status of the 4 to 20 mA DC output when an abnormal status is detected with the capsule or the amplifier as the result of self-diagnosis. One of the following statuses; last held, high limit, and low limit values, can be selected.

Range for 4 to 20 mA DC signal is set with actual input applied. Sets 20 mA DC output precisely with respect to user’s reference instrument output. Note that DPharp is calibrated with high accuracy before shipment, so span should be set using the normal range setup.

Adjusts zero point. This can be done either using the external zero-adjustment screw on the transmitteror using the BT200.

Adjust the characterization curve. All the transmitters are calibrated at factory and this adjustment is normally not necessary for most cases. Use for specific purposes.

Used for loop checks. Output can be set freely from –5% to 110% in 1% steps.

Allows user to enter up to 5 items of any desired text in up to 8 uppercase alphanumeric characters per item.

IMPORTANT

If the transmitter is turned off within 30 seconds after parameters have been set, the set data will not be stored and the terminal returns to previous settings.

(13) Range Change while Applying Actual

Inputs (H10: AUTO LRV, H11: AUTO HRV)

This feature allows the lower and higher range values to be set up automatically with the actual input applied. If the lower and higher range values are set, C21: LOW RANGE and C22: HIGH RANGE are changed at this same time.

Follow the procedure in the figure below. The measurement span is determined by the higher and lower range values. Changing the lower range value results in the higher range value changing automatically, keeping the span constant.

• Example 1: When changing the lower range value to 0.5 kPa for the present

setting of 0 to 30 kPa, take the following action with input pressure of 0.5 kPa applied.

SET H10:AUTO LRV 0 kPa + 0

(14) Zero Point Adjustment

(J10: ZERO ADJ, J11: ZERO DEV, J20: EXT ZERO ADJ)

The DPharp supports several adjustment methods. Select the method best suited for the conditions of your application. Note that output signal can be checked by displaying parameter A10:OUTPUT (%) on the BT200.

Adjustment Method Description

Using the BT200 Set the present input to 0%.

Adjust for 0% output at input level of 0%.

Adjust output to the reference value obtained using other means.

If the input level cannot easily be made 0% (because of tank level, etc.), adjust output to the reference value obtained using other means, such as a sight glass.

Using the external zero-adjustment screw

Adjust zero point using the zeroadjustment screw on the transmitter. This permits zero adjustment without using the BT200. Accurately adjust the output current to 4 mA DC or other target output value using an ammeter that accuratly reads output currents.

Adjustment Screw

• Enabling/inhibiting of zero point adjustment using the external zero-adjustment screw on the transmitter (J20: EXT ZERO ADJ)

(15) Span Adjustment

Each DPharp EJA series transmitter is factory characterized according to the specification. Mounting position effects or zero shifts caused by static pressure are typically compensated by a zero adjustment.

A span adjustment is a function to correct the slope error from a zero point in characterizing 100% point (HRV). This function can be used when span drifts may be caused or characterization to the specific pressure standard is required.

Therefore, the zero point adjustment should always be performed before the upper point adjustment in order to maintain the pitch between zero and 100% points within the calibration range.

You can manually perform the trimming procedure by using J15: SPAN ADJ.

• Span adjustment value The span adjustment value is calculated as follows.

• Zero point adjustment using external zero-adjustment screw on the transmitter

Turn the zero-adjustment screw on the outside of the transmitter case using a slotted screwdriver. Turn the screw to the right to increase the zero point or to the left to decrease the zero output; the zero adjusts in increments of 0.01% of the range setting. Note that the amount of adjustment to the zero point changes according to the speed at which the screw is turned. To make fine adjustments, turn the screw slowly; to make coarse adjustments, turn the screw quickly.

Note: When a zero point adjustment has been made, do not turn off

the transmitter less than 30 seconds after adjustment.

9. MAINTENANCE

9.1 Overview

WARNING

Since the accumulated process fluid may be toxic or otherwise harmful, take appropriate care to avoid contact with the body, or inhalation of vapors during draining condensate or venting gas in transmitter pressure-detector section and even after dismounting the instrument from the process line for maintenance.

Maintenance of the transmitter is easy due to its modular construction. This chapter describes the procedures for calibration, adjustment, and the disassembly and reassembly procedures required for component replacement.

Since the transmitters are precision instruments, carefully and thoroughly read the following sections for proper handling during maintenance.

IMPORTANT

• As a rule, maintenance of this transmitter should be implemented in a maintenance service shop where the necessary tools are provided.

• The CPU assembly contains sensitive parts that may be damaged by static electricity. Exercise care so as not to directly touch the electronic parts or circuit patterns on the board, for example, by preventing static electrification by using grounded wrist straps when handling the assembly. Also take precautions such as placing a removed CPU assembly into a bag with an antistatic coating.

9.2 Calibration Instruments Selection

Table 9.2.1 shows the instruments required for calibration. Select instruments that will enable the transmitter to be calibrated or adjusted to the required accuracy.

The calibration instruments should be handled carefully so as to maintain the specified accuracy.

9.3 Calibration

Use the procedure below to check instrument operation and accuracy during periodic maintenance or troubleshooting.

1) Connect the instruments as shown in Figure 9.3.1

and warm up the instruments for at least five minutes.

IMPORTANT

• To adjust the transmitter for highest accuracy, make adjustments with the power supply voltage and load resistance including leadwire resistances set close to the conditions under which the transmitter is installed.

• Dismount the manifold assembly(see Subsection 9.4.4) and apply reference pressure on the high pressure side. (The low pressure side should be open to atmosphere.)

• Do not perform the calibration procedure until the transmitter is at room temperature.

2) Apply reference pressures of 0%, 50%, and 100% of the measurement range to the transmitter. Calculate the errors (differences between digital voltmeter readings and reference pressures) as the pressure is increased from 0% to 100% and is decreased from 100% to 0%, and confirm that the errors are within the required accuracy.

Note: When the output mode is set to SQRT, apply reference

pressures of 0, 6.25, 25, 56.25, and 100%, instead.

INSTALLATION AND OPERATING PRECAUTIONS FOR TIIS INTRINSICALLY SAFE EQUIPMENT

Apparatus Certified Under Technical Criteria (IEC-compatible Standards) and from “RECOMMENDED PRACTICES for Explosion-Protected Electrical Installations in General Industries,” published in 1979

1. General

The following describes precautions on electrical apparatus of intrinsically safe construction (hereinafter referred to as intrinsically safe apparatus).

Following the Labor Safety and Health Laws of Japan, an intrinsically safe apparatus must undergo type tests in order to be certified by the Technical Institute of Industrial Safety, Inc. These tests are required to satisfy either the technical criteria for electrical machinery and equipment in compliance with explosionproof standards involving inflammable gases or vapors and for machinery and equipment having explosionproof performance (standards notification no. 556 from the Japanese Ministry of Labor) (hereinafter referred to as technical criteria), in conformity with IEC Standards, or the “Recommended Practice for Explosion-Protected Electrical Installations in General Industries,” published in

1979. Such a certified apparatus can be used in hazardous locations where inflammable gases or vapors may be present.

Certified apparatus includes a certification label and an equipment nameplate with the specifications necessary for explosion requirements as well as precautions on explosion protection. Please confirm these precautionary items and use them to meet specification requirements.

For electrical wiring and maintenance servicing, please refer to “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 intrinsically safe requirements, equipment that can be termed an “intrinsically safe apparatus” must:

(1) be certified by the Technical Institute of Industrial

Safety, Inc. in accordance with the Labor Safety and Health Laws of Japan and have the appropriate mark of certification labeled on its case, and

(2) be used in compliance with the specifications marked on

its certification label, equipment nameplate and precautionary information furnished.

Note: Intrinsically safe apparatus satisfy their performance under

specific conditions. They are not always absolutely safe under every operational and environmental condition. In other

words, they are not safe products involved with factors such as chemical reactions, geographical changes or the like other than affected by electric energy from the equipment itself.

2. Electrical Apparatus of Intrinsic Safety Type of Explosion-Protected Construction

The intrinsic safety type of explosion-protected construction is a method of protection applicable to a circuit or part of a circuit in which, under prescribed test conditions, no spark or thermal effect, whether produced normally or accidentally, is capable of causing a prescribed explosive gas to ignite. In other words, electrical apparatus of this construction is intended to suppress electrical energy thereby preventing ignition of a given explosive gas atmosphere even though spark or high thermal effect occurs in the electric circuitry.

Intrinsically safe electrical apparatus generally comprise intrinsically safe apparatus installed in a hazardous location and a safety barrier (associated apparatus), installed in a nonhazardous location, aimed at preventing electrical energy from flowing into the electric circuitry of intrinsically safe apparatus.

However, battery-operated, portable intrinsically safe apparatus or the like may be used alone.

3. Terminology

(1) Intrinsically safe apparatus: Electrical apparatus in which

all the circuits are intrinsically safe circuits.

(2) Associated apparatus: Electrical apparatus in which there

are both intrinsically safe circuits and non-intrinsically safe circuits that can affect the safety of intrinsically safe circuits.

(3) Safety barrier: A specific type of associated apparatus,

which consists mainly of safety barrier elements, and serves to limit the flow of excessive electrical energy, which is capable of causing ignition of a given explosive gas or vapour of a non-intrinsically safe circuit into concerned intrinsically safe circuits.

(4) Apparatus of category “ia”: Intrinsically safe electrical

apparatus and associated apparatus which are incapable of causing ignition of a given explosive gas or vapour with the appropriate safety factors such as:

EX-A03E

INSTALLATION AND OPERATING PRECAUTIONS FOR TIIS INTRINSICALLY SAFE EQUIPMENT

— when up to two countable faults are applied and, in

addition,

— when non-countable faults produce an onerous

condition.

(5) Apparatus of category “ib”: Intrinsically safe electrical

apparatus and associated apparatus which are incapable of causing ignition of a given explosive gas or vapour, with the appropriate safety factors such as: — when up to one countable fault is applied and, in

addition,

— when non-countable faults produce an onerous

condition.

(6) Safety rating: A rating to be designated to intrinsically

safe apparatus as well as associated apparatus and is the maximum rating allowable for maintaining intrinsic safety of concerned intrinsically safe circuits.

4. Caution on Combining Intrinsically Safe Apparatus and Safety Barriers

(1) A combination of certified intrinsically safe apparatus

and safety barriers needs to satisfy combination requirements. If intrinsically safe apparatus specify safety barriers for combination, safety barriers other than specified cannot be used (see Note 1 for more details).

(2) Certified intrinsically safe systems specify specific safety

barriers in combination with intrinsically safe apparatus. So safety barriers other than specified cannot be used (see Note 2 for more details).

(3) Other than limitations of combining intrinsically safe

apparatus and safety barriers as given in (1) and (2) above, two or more pieces of apparatus certified under different standards cannot be combined with each other (see Note 3 for more details). In addition, bear in mind that classifications of explosion protection such as “IIA,” “IIB” and “IIC” and category “ia” and “ib” limit a combination of intrinsically safe apparatus and safety barriers. For more details, see the “Type Certificate Guide for Explosion-Protected Constructionfor Electrical Machinery and Equipment,” issued by the Japanese Ministry of Labour, the Research Institute of Industrial Safety.

Note 1: Testing Apparatus

Intrinsically safe apparatus and safety barriers are assessed individually to ensure that their safety requirements are satisfied. Tested and certified intrinsically safe apparatus and safety barriers incorporate individual certification numbers. A combination of intrinsically safe apparatus and safety barriers involves the following two limitations: (1) A safety barrier which meets the combination require-

ments by referring to its safety rating and combination parameters shall be selected.

(2) For pressure transmitters, pH transmitters, temperature

detectors and the like, safety barriers that can be combined are already specified. Other safety barriers cannot be used.

Note 2: Testing Intrinsically Safe System

An assembly (as a system) in which intrinsically safe apparatus and safety barriers are combined is assessed to ensure that its safety requirements are satisfied. A tested and certified system incorporates a certification number (intrinsically safe apparatus and safety barriers have the same certification number).

Note 3: Impossible Combinations of Apparatus Certified Under

Different Standards Intrinsically safe apparatus certified under technical criteria and safety barriers certified under the “Recommended Practice for Explosion-Protected Electrical Installations in General Industries” (1979) and vice versa cannot be combined even if their combination requirements are satisfied.

5. Installation of Intrinsically Safe Apparatus and Safety Barriers

(1) Classification of installation location

Intrinsically safe apparatus may be installed, depending upon applicable gases, in a hazardous area in Zone 0, 1 or 2 (Note 4 below), where the specified gases are present. However, note that apparatus certified under Technical Criteria, in category “ib” shall be installed only in Zone 1 or 2. Safety barriers (associated apparatus) that are combined with these intrinsically safe apparatus shall be installed only in a nonhazardous area. In cases where safety barriers are installed in a hazardous area, they shall be enclosed, for example, in a flameproof enclosure.

Note 4: Hazardous areas are classified in zones based upon 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 is

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) Ambient temperature limits for intrinsically

safe apparatus

Intrinsically safe apparatus shall be installed in a location where the ambient temperature ranges from –20° to +40°C (for those certified under Technical Criteria) or –10° to +40°C (for those certified under the “Recommended Practice for Explosion-Protected Electrical Installations in General Industries” (1979). However, some field-mounted

EX-A03E

INSTALLATION AND OPERATING PRECAUTIONS FOR TIIS INTRINSICALLY SAFE EQUIPMENT

intrinsically safe apparatus may be used at an ambient temperature up to 60°C. So, specifications should be checked before installing intrinsically safe apparatus.

If the intrinsically safe apparatus are exposed to direct sunshine or radiant heat from plant facilities, appropriate thermal protection measures shall be taken.

6. Wiring for Intrinsically Safe Circuits

In intrinsically safe construction, safety shall be maintained as an intrinsically safe system involving intrinsically safe apparatus and safety barriers connected thereto, and electrical wiring (through intrinsically safe circuits) interconnected between them. In other words, even when safety requirements are maintained individually by intrinsically safe apparatus and safety barriers, they shall not be affected by electrical or magnetic energy caused by electrical wiring.

To make electrical wiring for intrinsically safe circuits, you must:

(a) refer to the equipment configuration diagram and make

electrical wiring properly;

(b) prevent intrinsically safe wiring from being contacted

with non-intrinsically safe wiring, and separate the intrinsically safe circuit from other electrical circuits;

electrostatically and magnetically affected by nonintrinsically safe wiring;

(d) reduce wiring inductance and capacitance produced

between the intrinsically safe apparatus and safety barrier where possible, and use a shorter cable between the intrinsically safe apparatus and safety barrier than specified if the maximum permissible inductance of the cable is specified as operating conditions;

(e) conform to conditions of installation such as wiring

method, earthing or the like, if any; and

(f) protect the outer sheath of cables from damage with

appropriate measures.

7. Maintenance and Inspection of Intrinsically Safe Apparatus and Safety Barriers

Installations for Explosive Gas Atmospheres in General Industry” issued in 1994 by the Japanese Ministry of Labour, the Research Institute of Industrial Safety.

(1) Requirements for maintenance personnel

Maintenance and inspection of intrinsically safe apparatus and safety barriers shall be conducted by maintenance personnel skilled in intrinsically safe construction and installation of electrical devices as well as capable of applying associated rules.

(2) Maintenance and Inspection

(a) Visual inspection

Visually inspect the external connections of intrinsically safe apparatus and safety barriers, and cables for damage or corrosion as well as other mechanical and structural defects.

(b) Adjustments

Zero, span and sensitivity adjustments shall be made with applicable adjusting potentiometers and mechanical adjustment screws. These maintenance adjustments shall be made in a nonhazardous location.

CAUTION

If intrinsically safe apparatus and safety barriers require maintenance service and checking, a gas detector shall be used to ensure that there is no explosive gas in the location (maintenance servicing shall be conducted in a nonhazardous location).

(3) Repair

Intrinsically safe apparatus and safety barriers shall be repaired by manufacturers.

(4) Prohibition of modifications and specifica-

tion changes

Do not attempt to make modifications or change specifications which may affect safety.

Maintenance and inspection of intrinsically safe apparatus and safety barriers shall be limited to within the instructions described in applicable instruction manuals. If other than this is required, contact the manufacturers. For more information, refer to the “USER’S GUIDELINES for Electrical

INSTALLATION AND OPERATING PRECAUTIONS FOR TIIS FLAMEPROOF EQUIPMENT

Apparatus Certified Under Technical Criteria (IEC-compatible Standards)

1. General

The following describes precautions on electrical apparatus of flameproof construction (hereinafter referred to as flameproof apparatus) in explosion-protected apparatus.

Following the Labour Safety and Health Laws of Japan, flameproof apparatus is subjected to type tests to meet either the technical criteria for explosionproof electrical machinery and equipment (standards notification 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 certified apparatus can be used in hazardous

locations where explosive or inflammable gases or vapours may be present.

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 flame caused by explosion does not ignite gases or vapours outside the enclosure.

In this manual, the word "flameproof" is applied to the flameproof equipment combined with the types of protection "e", "o", "i", and "d" as well as flameproof equipment.

The physical distance between two mating surfaces, or differences in diameters if the mating surfaces are cylindrical.

Note: The permissible sizes of gaps between joint surfaces, 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 classification of the specified gases and vapours.

INSTALLATION AND OPERATING PRECAUTIONS FOR TIIS FLAMEPROOF EQUIPMENT

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 specified gases are present. Those apparatus shall not be installed in a hazardous area in Zone 0.

Note: Hazardous areas are classified in zones based upon 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 is

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

The standard environmental condition for the installation of flameproof apparatus is limited to an ambient temperature range from –20°C to +40°C (for products certified under Technical Criteria). However, some field-mounted instruments may be certified at an ambient temperature up to +60°C as indicated on the instrument nameplates. If the flameproof apparatus are exposed to direct sunshine or radiant heat from plant facilities, appropriate thermal protection measures shall be taken.

5. External Wiring for Flameproof Apparatus

Flameproof apparatus require cable wiring or flameproof metal conduits for their electrical connections. For cable wiring, cable glands (cable entry devices for flameproof type) to wiring connections shall be attached. For metal conduits, attach sealing fittings as close to wiring connections as possible and completely seal the apparatus. All non-live metal parts such as the enclosure shall be securely grounded. For details, see 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 flameproof type) specified 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 waterproofing.

• Specific 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 flexible 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 fill the ducts with sand appropriately.

• When branch connections of cables, or cable connections with insulated cables inside the conduit pipes are made, a flameproof or increased-safety connection box shall be used. In this case, flameproof or increased-safety cable glands meeting the type of connection box must be used for cable connections to the box.

(2) Flameproof Metal Conduit Wiring

• For the flameproof metal conduit wiring or insulated wires shall be used as recommended by the USER’S GUIDELINES for Electrical Installations for Explosive Gas Atmospheres in General Industry, published in

1994.

• For conduit pipes, heavy-gauge steel conduits conforming to JIS C 8305 Standard shall be used.

• Flameproof sealing fittings shall be used in the vicinity of the wiring connections, and those fittings shall be filled with sealing compounds to complete sealing of the apparatus. In addition, to prevent explosive gases, moisture, or flame caused by explosion form being propagated through the conduit, always provide sealing fittings to complete sealing of the conduit in the following locations:

(a) In the boundaries between the hazardous and non-

hazardous locations.

(b) In the boundaries where there is a different

classification of hazardous location.

• For the connections of the apparatus with a conduit pipe or its associated accessories, G-type parallel pipe threads (JIS B 0202) shall be used to provide a minimum of five-thread engagement to complete tightness. In addition, since these parallel threads do not have sealing property, nonhardening sealant such as liquid gaskets shall thus be applied to those threads for ensuring waterproofness.

• If metal conduits need flexibility, use flameproof flexible fittings.

INSTALLATION AND OPERATING PRECAUTIONS FOR TIIS FLAMEPROOF EQUIPMENT

6. Maintenance of Flameproof Apparatus

To maintain the flameproof apparatus, do the following. (For details, see Chapter 10 “MAINTENANCE OF EXPLOSIONPROTECTED 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) Visual inspection

Visually inspect the flameproof apparatus, metal conduits, and cables for damage or corrosion, and other mechanical and structural defects.

(b) Zero and span adjustments

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 flameproof 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) Make only such electrical and mechanical repairs as will

restore the apparatus to its original condition. For the flameproof 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) If any damage occurs in threads, joints or mating

surfaces, inspection windows, connections between the transmitter and terminal box, shrouds or clamps, or external wiring connections which are essential in flameproofness, contact Yokogawa Electric Corporation.

requirements for flameproof apparatus (however, bear in mind that the apparatus must always be restored to its original condition). If you attempt to repair the flameproof apparatus, company-specified components shall be used.

(d) Before starting to service the apparatus, be sure to check

all parts necessary for retaining the requirements for flameproof apparatus. For this, check that all screws, bolts, nuts, and threaded connections have properly been tightened.

(3) Prohibition of specification changes and

modifications

Do not attempt to change specifications or make modifications 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 flameproof type) conforming to IEC Standards are certified in combination with the flameproof apparatus. So, Yokogawa-specified cable entry devices for flameproof type shall be used to meet this demand.
