clean the chambers inside the cover anges, so that there is no process uid remaining inside. Before placing it in storage, also make sure that the pressure-detector is securely connected to the transmitter section.

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.

IM 01C25F01-01E

<2. Handling Cautions>

2-2

(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 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 certied for installation in a hazardous area containing specic gas types. See subsection

2.9 “Installation of an Explosion-Protected Transmitters.”

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 uid.

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

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 rmly.

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

piping.

specied maximum working pressure.

2.6 Waterproong of Cable Conduit Connections

Apply a non-hardening sealant to the threads to waterproof the transmitter cable conduit connections. (See gure 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 rst observed.

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.

IM 01C25F01-01E

<2. Handling Cautions>

2-3

(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.

all signal lines from the transmitter 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.

2.9 Installation of an ExplosionProtected Instrument

NOTE

For FOUNDATION Fieldbus explosion protected type, please refer to IM 01C22T02-01E. For PROFIBUS PA explosion protected type, please refer to IM 01C25T04-01EN.

If a customer makes a repair or modication to an intrinsically safe or explosionproof instrument and the instrument is not restored to its original condition, its intrinsically safe or explosionproof construction may be compromised and the instrument may be hazardous to operate. Please contact Yokogawa before making any repair or modication to an instrument.

CAUTION

This instrument has been tested and certied as being intrinsically safe or explosionproof. Please note that severe restrictions apply to this instrument’s construction, installation, external wiring, maintenance and repair. A failure to abide by these restrictions could make the instrument a hazard to operate.

• 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.

WARNING

Maintaining the safety of explosionproof equipment requires great care during mounting, wiring, and piping. Safety requirements also place restrictions on maintenance and repair. Please read the following sections very carefully.

WARNING

The range setting switch must not be used in a hazardous area.

Before installing the transmitter, read the cautionary notes in section 2.4, “Selecting the Installation Location.” For additional information on the ambient conditions allowed at the installation location, refer to section 9.1 “Standard Specications.”

IMPORTANT

• When welding piping during construction, take care not to allow welding currents to ow through the transmitter.

• Do not step on this instrument after installation.

• For the EJ530 and EJX630A whose capsule code is A, B or C, the pipe of the atmospheric opening is located on the pressure detecting section. The opening must not face upward. See subsection 5.1.1.

• D capsule of EJ530 and EJX630A is of sealed gauge reference and the change in atomospheric pressure may affect the measurement.

IMPORTANT

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

F0404.ai

1) Remove the two setscrews that fasten the transmitter section and capsule assembly, using the Allen wrench.

2) Rotate the transmitter section slowly and stop it at designated position. For the EJ530 and EJX630A whose capsule code is A, B or C, the pipe of the atmospheric opening may interfere with the stopper and disturb further rotation. In that case, screw off the pipe rst, rotate the housing, and then screw in the pipe by hand again.

3) Tighten the two setscrews to a torque of

1.5 N·m.

IMPORTANT

Do not rotate the transmitter section more than the above limit.

An integral indicator can be installed in the following three directions. Follow the instructions in section 8.4 for removing and attaching the integral indicator.

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 liquidlled impulse line, or the drain for a gas-lled 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 uid (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

IMPORTANT

The transmitter can be installed in horizontal impulse piping conguration, tilting the transmitter's position up to 90°. When tilting, observe that the pipe (for Model EJ530 and EJX630A with measurement span code A, B, and C) is positioned horizontal downwards, or any place between them, as shown in Figure 5.1 The zero-adjustment screw must be positioned downwards for all the models.

The pipe (open to atmosphere) is positioned horizontal.

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 gure 5.2 according to the kind of uid being measured.

NOTE

• If the process uid is a gas, the taps must be vertical or within 45° either side of vertical.

• If the process uid is a liquid, the taps must be horizontal or below horizontal, but not more than 45° below horizontal.

• If the process uid is steam or other condensing vapor, the taps must be horizontal or above horizontal, but not more than 45° above horizontal.

If the zero-adjustment screw is positioned other than donwards after installation, rotate the housing unitl it is positioned downwards.

Figure 5.1 Horizontal Impulse Piping Connection

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 uid is a gas, then as a rule the transmitter must be located higher than the process pressure taps.

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

IM 01C25F01-01E

<5. Installing Impulse Piping>

5-2

(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.

(4) Preventing Freezing

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

NOTE

After completing the connections, close the valves on the process pressure taps (main valves), the valves at the transmitter (stop valves), and the impulse piping drain valves, so that condensate, sediment, dust and other extraneous material cannot enter the impulse piping.

5.2 Impulse Piping Connection Examples

Figure 5.3 shows 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 uid (corrosiveness, toxicity, ammability, etc.), in order to make appropriate changes and additions to the connection congurations.

Note the following points when referring to these piping examples.

• 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 (anged, screwed, welded), construction (globe, gate, or ball valve), temperature and pressure. Select the type of valve most appropriate for the application.

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 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 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.

NOTE

If any of the above errors are indicated on the display of the integral indicator or the communicator, refer to subsection 8.5.3 for the corrective action.

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.

NOTE

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.

■ Verify and Change Transmitter Parameter Setting and Values

The parameters related to the following items are set at factory as specied in order.

• Calibration range

• Integral indicator display

• Software damping (optional) Other parameters like following are shipped with the default setting.

• Low-cut

• Process alarm setting

• Signal characterizer

• Write protection To conrm or change the values, see IM 01C25T0106EN or 01C25T03-01E.

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.

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 ll 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 ll plug and then gradually open the tap valve.

IM 01C25F01-01E

<7. Operation>

7-3

Use a slotted screwdriver to turn the zeroadjustment 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 ne adjustment and quickly to make a rough adjustment.

(2) When you cannot obtain the Low Range

Value from the actual measured value of 0%;

Adjust the transmitter output to the actual measured value obtained by a digital manometer or a glass gauge.

[Example]

(=10.4mA)

IMPORTANT

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

• Close the terminal box cover and the amplier 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, conrm that they are secure and cannot be opened by hand. Tighten the zero-adjustment cover mounting screw to secure the cover.

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

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 specic to the differential pressure transmitters.

1) Conrm the operating status. If the output signal exhibits wide uctuations (hunting) due to periodic variation in the process pressure, use the communicator to dampen the transmitter output signal. Conrm the hunting using a receiving instrument or the integral indicator, and set the optimum damping time constant.

2) After conrming the operating status, perform the following.

7.4 Shutting Down the Transmitter

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

1) Turn off the power.

2) Close the stop valve.

3) Open the equalizing valve.

4) Close the high pressure stop valve.

5) Close the tap valves.

NOTE

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

• The equalizing valve must be left OPEN.

7.5 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 range-setting 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.

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.

1) Connect the transmitter and apparatus as shown in Figure 8.1 and warm it up for at least ten 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.

(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.

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

7) Apply a pressure of 3 MPa 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 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.

8.1 Overview

WARNING

Since the accumulated process uid 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.

8.3 Calibration

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

1) Connect the instruments as shown in gure 8.1 and warm up the instruments for at least ten 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 gure. 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 conrm that the errors are within the required accuracy.

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 specied accuracy.

CAUTION

Precautions for ATEX Flameproof Type Transmitters

• Flameproof type transmitters must be, as a rule, removed to a non-hazardous area for maintenance and be disassembled and reassembled to the original state.

• On the ameproof type transmitters the two covers are locked, each by an Allen head bolt (shrouding bolt). When a 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.

When a cover is closed it should be locked

by a shrouding bolt without fail. Tighten the shrouding bolt to a torque of 0.7 N·m.

8.4.1 Replacing the Integral Indicator

CAUTION

Cautions for Flameproof Type Transmitters

Users are prohibited by law from modifying the construction of a ameproof 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 ameproof type transmitter with its integral indicator removed, or from adding an integral indicator to a transmitter. If such modication is absolutely required, contact Yokogawa.

This subsection describes the procedure for replacing an integral indicator. (See gure 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

1) Align both the LCD board assembly and CPU assembly connectors and engage them.

2) Insert and tighten the two mounting screws.

3) Replace the cover.

8.4.2 Replacing the CPU Board Assembly

This subsection describes the procedure for replacing the CPU assembly. (See gure 8.3)

■ Removing the CPU Assembly

1) Remove the cover. If an integral indicator is mounted, refer to subsection 8.4.1 and remove the indicator.

2) Turn the zero-adjustment screw to the position (where the screw head slot is horizontal) as shown in gure 8.3.

3) Disconnect the output terminal cable (cable with brown connector at the end). When doing this, lightly press the side of the CPU assembly connector and pull the cable connector to disengage.

4) Use a socket driver (width across ats, 5.5mm) to loosen the two bosses.

5) Carefully pull the CPU assembly straight forward to remove it.

6) Disconnect the at cable (cable with white connector at the end) that connects the CPU assembly and the capsule.

NOTE

Be careful not to apply excessive force to the CPU assembly when removing it.

■ Mounting the CPU Assembly

1) Connect the at cable (with white connector) between the CPU assembly and the capsule.

2) Connect the output terminal cable (with brown connector).

NOTE

Make certain that the cables do not get pinched between the case and the edge of the CPU assembly.

NOTE

Conrm that the zero-adjustment screw pin is placed properly in the groove on the bracket prior to tightening the two bosses. If it is not, the zeroadjustment mechanism will be damaged.

5) Replace the cover.

8.4.3 Cleaning and Replacing the Capsule

Assembly

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

CAUTION

Cautions for Flameproof Type Transmitters

Users are prohibited by law from modifying the construction of a ameproof 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 ameproof 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 amplier case.

4) Tighten the two bosses. If the transmitter is equipped with an integral indicator, refer to subsection 8.4.1 to mount the indicator.

■ Removing the Capsule Assembly

IMPORTANT

Exercise care as follows when cleaning the capsule assembly.

• Handle the capsule assembly with care, and be especially careful not to damage or distort the diaphragms that contact the process uid.

• Do not use a chlorinated or acidic solution for cleaning.

• Rinse thoroughly with clean water after cleaning.

1) Remove the CPU assembly as shown in subsection 8.4.2.

2) Remove the two setscrews that connect the transmitter section and pressure-detector section.

3) Remove the hexagon-head screw and the stopper.

4) Separate the transmitter section and capsule assembly.

5) Clean the capsule assembly or replace with a new one.

■ Reassembling the Capsule Assembly

1) Insert the capsule assembly to the transmitter section. Reattach the sopper with the hexagonhead screw.

2) Tighten the two setscrews. (Tighten the screws to a torque of 1.5 N·m)

3) Install the CPU assembly according to subsection 8.4.2.

4) After completing reassembly, adjust the zero point and recheck the parameters.
