2. HANDLING CAUTIONS

2.4 Selecting the Installation Location

The transmitter 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 significant 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 transmitter 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.

Although the transmitter 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 Transmitters

An explosion-protected transmitters is certified for installation in a hazardous area containing specific gas types. See subsection 2.9 “Installation of an Explosion-Protected Transmitters.”

(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 6.8, 6.9 and 6.10.)

2.7 Restrictions on Use of Radio Transceivers

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 this, start out from a distance of several meters and slowly approach the transmitter with the transceiver while observing the measurement loop for noise effects. Thereafter use the transceiver outside the range where the noise effects were first observed.

2.5 Pressure Connection

WARNING

•Never loosen the process connector bolts when an instrument is installed in a process. The device is under pressure, and a loss of seal can result in a sudden and uncontrolled release of process fluid.

•When draining toxic process fluids that have condensed inside the pressure detector, take appropriate steps to prevent the contact of such fluids with the skin or eyes and the inhalation of vapors from these fluids.

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

(a) Make sure that all the process connector bolts are

tightened firmly.

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. 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.

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

2-2

IM 01C25B01-01E

Page 10

2. HANDLING CAUTIONS

• 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 briefly 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) Technical Data

• Models without /PE3

directive 97/23/EC, which corresponds to Article 3, Paragraph 3 of PED, denoted as Sound Engineering Practice (SEP).

EJX440A, EJX510A-D, and EJX530A-D can be used above 200 bar and therefore considered as a part of a pressure retaining vessel where category III, Module H applies. These models with option code /PE3 conform to that category.

Article 3, Paragraph 3 of PED, denoted as Sound

Engineering Practice (SEP).

• Models with /PE3

Module : H

(3) Operation

CAUTION

•The temperature and pressure of fluid should be maintained at levels that are consistent with normal operating conditions.

•The ambient temperature should be maintained at a level that is consistent with normal operating conditions.

•Please take care to prevent water hammer and the like from inducing excessive pressures in pipes and valves. If phenomena are likely, install a safety valve or take some other appropriate measure to prevent pressure from exceeding PS.

•Take appropriate measures at the device or system level to protect transmitters if they are to be operated near an external heat source.

IMPORTANT

This section is applicable only for EJX110A and EJX130A differential transmitters, and not applicable for gauge or absolute pressure transmitters.

4.4.1 Rotating Pressure-detector Section

180

This procedure can be applied only to a transmitter with a vertical impulse piping type.

The procedure below can be used to turn the pressure detector assembly 180°. Perform this operation in a maintenance shop with the necessary tools laid out and ready for use, and then install the transmitter in the field after making the change.

1) Use an Allen wrench (JIS B4648, nominal 2.5 mm)

to remove the two setscrews at the joint between the pressure-detector section and transmitter section.

2) Leaving the transmitter section in position, rotate

the pressure-detector section 180°.

3) Tighten the two setscrews to fix the pressure-

detector section and transmitter section together (at a torque of 1.5 N·m). Reposition the process connector and drain (vent) plugs to the opposite side as described in subsection

4.3.

4.4.2 Using the Communicator

This method is applicable only to the Model EJX110A and EJX130A.

With a communicator, you can change which process connection is used as the high-pressure side without mechanically rotating the pressure-detector section 180 as described in subsection 4.4.1. To change, call parameter ‘D15: H/L SWAP’ for BRAIN Communication or ‘H/L swap’ for HART Communication and select REVERSE (right side: low pressure; left side: high pressure) or select NORMAL to change back to normal (right side: high pressure; left side: low pressure).

5. INSTALLING IMPULSE PIPING

5.1 Impulse Piping Installation Precautions

The impulse piping that connects the process outputs to the transmitter must convey the process pressure accurately. If, for example, gas collects in a liquidfilled impulse line, or the drain for a gas-filled impulse line becomes plugged, it will not convey the pressure accurately. Since this will cause errors in the measurement output, select the proper piping method for the process fluid (gas, liquid, or steam). Pay careful attention to the following points when routing the impulse piping and connecting the impulse piping to a transmitter.

5.1.1 Connecting Impulse Piping to a

Transmitter

(1) Check the High and Low Pressure Connec-

tions on the Transmitter (Figure 5.1)

Symbols “H” and “L” have been placed on the capsule assembly to indicate high and low pressure side. With differential pressure transmitters, connect the high pressure side impulse line to the “H” side, and the low pressure side impulse line to the “L” side.

With gauge/absolute pressure transmitters, connect the impulse line to the ‘H’ side.

(2) Changing the Process Connector Piping

Connections (Figure 4.1) (for differential pressure transmitters)

The impulse piping connection distances can be changed between 51 mm, 54 mm and 57 mm by changing the orientation of the process connectors. This is convenient for aligning an impulse line with a process connectors.

(3) Tightening the Process Connector Mount-

ing Bolts

After connecting an impulse line, tighten the process connector mounting bolts uniformly.

(4) Removing the Impulse Piping Connecting

Port Dustproof Cap

The impulse piping connecting port on the transmitter is covered with a plastic cap to keep out dust. This cap must be removed before connecting the line. (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) Connecting the Transmitter and 3-Valve

Manifold (for differential pressure transmitters)

A 3-valve manifold consists of two stop valves to block process pressure and an equalizing valve to equalize the pressures on the high and low pressure sides of the transmitter. Such a manifold makes it easier to disconnect the transmitter from the impulse piping, and is convenient when adjusting the transmitter zero point.

There are two 3-valve manifold types: the pipemounting type and the direct-mounting type; care should be taken with respect to the following points when connecting the manifold to the transmitter.

 Pipe-Mounting Type 3-Valve Manifold

(Figure 5.2)

1) Screw nipples into the connection ports on the transmitter side of the 3-valve manifold, and into the impulse piping connecting ports on the process connectors. (To maintain proper sealing, wind sealing tape around the nipple threads.)

2) Mount the 3-valve manifold on the 50 mm (2-inch) pipe by fastening a U-bolt to its mounting bracket. Tighten the U-bolt nuts only lightly at this time.

3) Install the pipe assemblies between the 3-valve

NOTE

manifold and the process connectors and lightly tighten the ball head lock nuts. (The ball-shaped ends of the pipes must be handled carefully, since they will not seal properly if the ball surface is scratched or otherwise damaged.)

4) Now tighten the nuts and bolts securely in the following sequence: Process connector bolts → transmitter-end ball head lock nuts → 3-valve manifold ball head lock nuts → 3-valve manifold mounting bracket U-bolt nuts

5. INSTALLING IMPULSE PIPING

After completing the connection of the transmitter and 3-valve manifold, be sure to CLOSE the low pressure and high pressure stop valves, OPEN the equalizing valve, and leave the manifold with the equalizing valve OPEN. You must do this in order to avoid overloading the transmitter from either the high or the low pressure side when beginning operation. This instruction must also be followed as part of the startup procedure (chapter 7.)

5.1.2 Routing the Impulse Piping

(1) Process Pressure Tap Angles

If condensate, gas, sediment or other extraneous material in the process piping gets into the impulse piping, pressure measurement errors may result. To prevent such problems, the process pressure taps must be angled as shown in figure 5.4 according to the kind of fluid being measured.

F0502.EPS

 Direct-Mounting Type 3-Valve Manifold

(Figure 5.3)

1) Mount the 3-valve manifold on the transmitter. (When mounting, use the two gaskets and the four bolts provided with the 3-valve manifold. Tighten the bolts evenly.)

2) Mount the process connectors and gaskets on the top of the 3-valve manifold (the side on which the impulse piping will be connected).

5. INSTALLING IMPULSE PIPING

NOTE

(2) Position of Process Pressure Taps and

Transmitter

If condensate (or gas) accumulates in the impulse piping, it should be removed periodically by opening the drain (or vent) plugs. However, this will generate a transient disturbance in the pressure measurement, and therefore it is necessary to position the taps and route the impulse piping so that any extraneous liquid or gas generated in the leadlines returns naturally to the process piping.

• If the process fluid is a gas, then as a rule the transmitter must be located higher than the process pressure taps.

• If the process fluid is a liquid or steam, then as a rule the transmitter must be located lower than the process pressure taps.

(3) Impulse Piping Slope

The impulse piping must be routed with only an upward or downward slope. Even for horizontal routing, the impulse piping should have a slope of at least 1/10 to prevent condensate (or gases) from accumulating in the pipes.

(6) Preventing Wind Speed Effects in Very

Low Differential Pressure Measurement (for differential pressure transmitters)

IMPORTANT

When using a differential pressure transmitter to measure very low pressures (draft pressure), the low pressure connection port is left open to atmospheric pressure (the reference pressure). Any wind around the differential pressure transmitter will therefore cause errors in the measurement. To prevent this, it will be necessary either to enclose the transmitter in a box, or to connect an impulse line to the low pressure side and insert its end into a wind-excluding pot (cylindrical with a base plate).

(7) Preventing Freezing

If there is any risk that the process fluid in the impulse piping or transmitter could freeze, use a steam jacket or heater to maintain the temperature of the fluid.

(4) Temperature Difference Between Impulse

Lines (for differential pressure transmitters)

If there is a temperature difference between the high and low impulse lines, the density difference of the fluids in the two lines will cause an error in the measurement pressure. When measuring flow, impulse lines must be routed together so that there is no temperature difference between them.

(5) Condensate Pots for Steam Flow Measure-

ment (for differential pressure transmitters)

If the liquid in the impulse piping repeatedly condenses or vaporizes as a result of changes in the ambient or process temperature, this will cause a difference in the fluid head between the high pressure and low pressure sides. To prevent measurement errors due to these head differences, condensate pots are used when measuring steam flow.

After completing the connections, close the valves on the process pressure taps ( valves at the transmitter (

main valves

stop valves

), the

), and the impulse piping drain valves, so that condensate, sediment, dust and other extraneous material cannot enter the impulse piping.

5. INSTALLING IMPULSE PIPING

5.2 Impulse Piping Connection Examples

Figure 5.5 and 5.6 show examples of typical impulse piping connections. Before connecting the transmitter to the process, study the transmitter installation location, the process piping layout, and the characteristics of the process fluid (corrosiveness, toxicity, flammability, etc.), in order to make appropriate changes and additions to the connection configurations.

Note the following points when referring to these piping examples.

• The high pressure connecting port on the transmitter is shown on the right (as viewed from the front).

• The transmitter impulse piping connection is shown for a vertical impulse piping connection configuration in which the direction of connection is either upwards or downwards.

• If the impulse line is long, bracing or supports should be provided to prevent vibration.

• The impulse piping material used must be compatible with the process pressure, temperature, and other conditions.

•A variety of process pressure tap valves (main valves) are available according to the type of connection (flanged, screwed, welded), construction (globe, gate, or ball valve), temperature and pressure. Select the type of valve most appropriate for the application.

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 the 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 ATEX flameproof type transmitters. 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 8.4 “Disassembly and Reassembly” for details.

• Plug and seal an unused conduit connection.

7. OPERATION

7.1 Preparation for Starting Operation

This section describes the operation procedure for the EJX110A as shown in figure 7.1a (vertical impulse piping type, high-pressure connection: right side) when measuring the liquid flow rate, and EJX430A and EJX310A as shown in figure 7.1b when measuring pressure.

NOTE

Check that the process pressure tap valves, drain valves, and 3-valve manifold stop valves on both the low pressure and high pressure sides are closed, and that the 3-valve manifold equalizing valve is opened.

(a) Follow the procedures below to introduce process

pressure into the impulse piping and transmitter.

 Differential Pressure Transmitters

1) Open the low pressure and high pressure tap valves

to fill the impulse piping with process liquid.

2) Slowly open the high pressure stop valve to fill the

transmitter pressure-detector section with process liquid.

3) Close the high pressure stop valve.

4) Gradually open the low pressure stop valve and

completely fill the transmitter pressure-detector section with process liquid.

5) Close the low pressure stop valve.

6) Gradually open the high pressure stop valve. At this

time, equal pressure is applied to the low and high pressure sides of the transmitter.

7) Check that there are no liquid leaks in the impulse

piping, 3-valve manifold, transmitter, or other components.

 Gauge/Absolute Pressure Transmitters

1) Open the tap valve (main valve) to fill the impulse

piping with process fluid.

2) Gradually open the stop valve to introduce process

fluid into the transmitter pressure-detector section.

3) Confirm that there is no pressure leak in the

impulse piping, transmitter, or other components.

Venting Gas from the Transmitter Pressuredetector 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 selfventing, refer to subsection 7.5 for instructions. Leave the equalizing valve open even after venting gas.

(b) Turn ON power and connect the communicator.

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

7.2 Zero Point Adjustment

After completing preparations for operating the transmitter, adjust the zero point.

Zero point adjustment can be done by turning the transmitter’s zero-adjustment screw or by using the communicator. This section describes the procedure for the zero-adjustment screw. For the communicator procedure, see the communication manual.

IMPORTANT

Do not turn off the power to the transmitter immediately after performing a zero point adjustment. Powering off within 30 seconds of performing this procedure will return the zero point to its previous setting.

Before performing this adjustment, make sure that the external zero adjustment function has NOT been disabled by a parameter setting.

To check the output signal, use a digital multimeter, calibrator, or communicator.

The zero-adjustment screw is located inside the cover. Use a slotted screwdriver to turn the zero-adjustment screw. Equalize the transmitter, then turn the screw clockwise to increase the output or counterclockwise to decrease the output. The zero point adjustment can be made with a resolution of 0.01% of the setting range. The degree of zero adjustments varies with the screw turning speed; turn the screw slowly to make a fine adjustment, quickly to make a rough adjustment.

When using differential pressure transmitters for level measurement and if you cannot obtain the lower range value from the actual measurement value of 0%, refer to subsection 7.2.2(2).

7.2.2 Adjusting Zero Point for Gauge/ Absolute Pressure Transmitters

(1) When you can obtain the Low Range

Value from the actual measured value of 0% (0 kPa, atmospheric pressure);

For pressure measurement using gauge pressure transmitters, follow the steps below before performing zero point adjustment.

1) Close the tap valve (main valve).

2) Loosen the fill plug so that the pressure applied to

the transmitter is only the head of the seal liquid.

3) Adjust the zero point at this status.

4) After the adjustment, close the fill plug and then

gradually open the tap valve.

Use a slotted screwdriver to turn the zero-adjustment screw. Turn the screw clockwise to increase the output or counterclockwise to decrease the output. The zero point adjustment can be made with a resolution of

0.01% of the setting range. Since the degree of the zero

adjustment varies with the screw turning speed, turn the screw slowly to make a fine adjustment and quickly to make a rough adjustment.

Turn the screw to match the output signal to the actual measured value.

7.3 Starting Operation

After completing the zero point adjustment, follow the procedures below to start operation. Steps 1) and 2) are specific to the differential pressure transmitters.

1) Close the equalizing valve.

2) Gradually open the low pressure stop valve. 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 the communicator to dampen the transmitter output signal. Confirm the hunting using a receiving instrument or the integral indicator, and set the optimum damping time constant.

4) After confirming the operating status, perform the following.

IMPORTANT

• Remove the communicator from the terminal box, and confirm that none of the terminal screws are loose.

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

• There are two covers that must be locked on the ATEX Flameproof type transmitters. An Allen head bolt (shrouding bolt) under the edge of each cover is used to lock the cover. When the shrouding bolt is driven counterclockwise with an Allen wrench, the bolt rotates upward and locks the cover. (See section 8.4.) After locking the covers, confirm that they are secure and cannot be opened by hand. Tighten the zero-adjustment cover mounting screw to secure the cover.

7. OPERATION

• Tighten the zero-adjustment cover mounting screw to secure the cover.

7.4 Shutting Down the Transmitter

Shut down the transmitter as follows. Steps 2) and 3) are specific to the differential pressure transmitters.

1) Turn off the power.

2) Close the low pressure stop valve.

3) Open the equalizing valve.

4) Close the high pressure stop valve.

5) Close the high pressure and low pressure tap

valves.

NOTE

•Whenever shutting down the transmitter for a long period, remove any process fluid that is in the transmitter pressure-detector section.

•The equalizing valve must be left OPEN.

7.5.1 Draining Condensate

1) Gradually open the drain screw or drain plug and drain the transmitter pressure-detector section. (See figure 7.5.)

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, and the drain plug to a torque of 34 to 39 N·m.

Figure 7.5 Draining the Transmitter

7.5 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 disturbs the pressure measurement, 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.

7.5.2 Venting Gas

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

7.6.)

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

3) Tighten the vent screw to a torque of 10 N·m.

7. OPERATION

7.6 Setting the Range Using the Range-setting Switch

WARNING

The range setting switch must not be used in the hazardous area. When it is necessary to use the switch, operate it in a non-hazardous location.

When pressure is applied to the transmitter, the lowand high-limit values for the measurement range (LRV and URV) can be changed (re-ranged) using the rangesetting switch (push-button) located on the optional integral indicator plate and the external zero adjustment screw. This procedure does not require use of the communicator. However, changes in the scale range and engineering unit display settings for the integral indicator require use of the communicator.

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

[Example]

Rerange LRV to 0 and URV to 3 MPa.

1) Connect the transmitter and apparatus as shown in

Figure 8.1 and warm it up for at least five minutes.

2) Press the range-setting push-button.

The integral indicator then displays “LRV.SET.”

3) Apply a pressure of 0 kPa (atmospheric pressure) to

the transmitter.

4) Turn the external zero-adjustment screw in the

desired direction. The integral indicator displays the output signal in %.

5) Adjust the output signal to 0% (1 V DC) by rotating

the external zero-adjustment screw. Doing so completes the LRV setting.

6) Press the range-setting push-button. The integral

indicator then displays “URV.SET.”

7) Apply a pressure of 3 MPa to the transmitter.

8) Turn the external zero-adjustment screw in the

desired direction. The integral indicator displays the output signal in %.

9) Adjust the output signal to 100% (5 V DC) by

rotating the external zero-adjustment screw. Doing so completes the URV 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 3 MPa.

(Note 1)

(Note 2)

(Note 1)

(Note 2)

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 URV), the integral indicator may display error number “AL.30” (In this case, the output signal percent and “AL.30” are displayed alternately every two seconds). Although “AL.30” is displayed, you may proceed to the next step. However, should any other error number be displayed, take the appropriate measure in reference to , “Errors and Countermeasures” in each communication manual.

IMPORTANT

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

• Changing LRV automatically changes URV to the following value.

URV = previous URV + (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.

8. MAINTENANCE

8.1 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 when draining condensate or venting gas from the 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.

Transmitters are precision instruments. Please carefully and thoroughly read the following sections for information on how to properly handle them while performing maintenance.

IMPORTANT

• As a rule, maintenance of this transmitter should be done in a shop that has all the necessary tools.

• The CPU assembly contains sensitive parts that can be damaged by static electricity. Take precautions such as using a grounded wrist strap when handling electronic parts or touching the board circuit patterns. Also be sure to place the removed CPU assembly into a bag with an antistatic coating.

8.2 Calibration Instruments Selection

Table 8.1 lists the instruments that can be used to calibrate a transmitter. When selecting an instrument, consider the required accuracy level. Exercise care when handling these instruments to ensure they maintain the specified accuracy.

8.3 Calibration

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

1) Connect the instruments as shown in figure 8.1 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.

• If the measurement range 0% point is 0 kPa or shifted in the positive direction (suppressed zero), the reference pressure should be applied as shown in the figure. If the measurement range 0% point is shifted in the negative direction (elevated zero), the reference pressure should be applied using a vacuum pump.

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.

8.4.1 Replacing the Integral Indicator

CAUTION

Cautions for Flameproof Type Transmitters

Users are prohibited by law from modifying the construction of a flameproof type transmitter. This would invalidate the agency approval for the use of the transmitter in a rated area. It follows that the user is prohibited from using a flameproof type transmitter with its integral indicator removed, or from adding an integral indicator to a transmitter. If such modification is absolutely required, contact Yokogawa.

This subsection describes the procedure for replacing an integral indicator. (See figure 8.3)

 Removing the Integral Indicator

1) Remove the cover.

2) While supporting the integral indicator with one hand, loosen its two mounting screws.

3) Dismount the LCD board assembly from the CPU assembly.

When doing this, carefully pull the LCD board assembly straight forward so as not to damage the connector pins between it and the CPU assembly.

 Attaching the Integral Indicator

8.4.3 Cleaning and Replacing the Capsule Assembly

This subsection describes the procedures for cleaning and replacing the capsule assembly. (See figure 8.4.)

CAUTION

Cautions for Flameproof Type Transmitters

Users are prohibited by law from modifying the construction of a flameproof type transmitter. If you wish to replace the capsule assembly with one of a different measurement range, contact Yokogawa. The user is permitted, however, to replace a capsule assembly with another of the same measurement range. When doing so, be sure to observe the following.

• The replacement capsule assembly must have the same part number as the one being replaced.

• The section connecting the transmitter and capsule assembly is a critical element in preservation of flameproof performance, and must be checked to verify that it is free of dents, scratches, and other defects.

• After completing maintenance, be sure to securely tighten the setscrews that fasten the transmitter section and pressure-detector section together.

3) Align and engage the zero-adjustment screw pin with the groove on the bracket on the CPU assembly. Then insert the CPU board assembly straight onto the post in the amplifier case.
