2. HANDLING CAUTIONS

This chapter describes important cautions regarding how to handle the transmitter. Read carefully before using the transmitter.

2. HANDLING CAUTIONS

The EJA-A Series pressure transmitters are thoroughly tested at the factory before shipment. When the transmitter is delivered, visually check them to make sure that no damage occurred during shipment.

Also check that all transmitter mounting hardware shown in Figure 2.1 is included. If the transmitter was ordered without the mounting bracket or without the process connector, the transmitter mounting hardware is not included. After checking the transmitter, repack it in the way it was delivered until installation.

2.2 Unpacking

When moving the transmitter to the installation site, keep it in its original packaging. Then, unpack the transmitter there to avoid damage on the way.

2.3 Storage

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

(a) Select a storage area which meets the following

conditions:

• It is not exposed to rain or 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.

2.1 Model and Specifications Check

The model name and specifications are indicated on the name plate attached to the case. If the reverse operat- ing mode was ordered (reverse signal), ‘REVERSE’ will be inscribed in field *1.

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

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

thoroughly clean the chambers inside the cover flanges, so that no measured fluid remains in it. Also make sure before storing that the pressuredetector and transmitter section are securely mounted.

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.

2-1

IM 01C21D01-01E

2. HANDLING CAUTIONS

(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 two process connector 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 6.4.2c.)

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.

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 M1.

4) After completing the test and being very careful not

to touch exposed conductors disconnect the insulation tester and connect a 100 k1 resistor between the grounding terminal and the short-

IM 01C21D01-01E

2. HANDLING CAUTIONS

circuiting 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.

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 piping, or the drain of a gas-filled impulse piping becomes plugged, the impulse piping 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 the transmitter.

5.1.1 Connecting Impulse Piping to the

Transmitter

(1) Connecting the Impulse Piping to the

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 5.1.2 according to the kind of fluid being measured.

NOTE

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

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

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

(2) Tightening the Process Connector Mount-

ing Bolts

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

(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.

IM 01C21D01-01E

5. INSTALLING IMPULSE PIPING

(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 fluid in the impulse piping or transmitter could freeze, use a steam jacket or heater to maintain the temperature of the fluid.

NOTE

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.

5.2 Impulse Piping Connection Examples

Figure 5.2 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 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 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 piping 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.

6.1 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 and IECEx 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 by hand. See Subsection 9.4 “Disassembly and Reassembly” for details.

7.1 Preparation for Starting Operation

7. OPERATION

The Model EJA310A, EJA430A and EJA440A pressure transmitter measures the pressure of liquids, gases, and steam. This section describes the operation procedure for the EJA430A as shown in Figure 7.1 (vertical impulse piping type, high-pressure connection: right side) when measuring a pressure.

NOTE

Confirm that the process pressure tap valve, drain valve, and stop valve are closed.

(a) Introduce a process fluid into the impulse piping

and then to the transmitter in the following procedure:

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.

(b) Turn ON power and connect the BT200.

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

 Verify and Change Transmitter Parameter

Setting and Values

The following parameters are the minimum settings required for operation. The transmitter has been shipped with these parameters. To confirm or change the values, see Subsection 8.3.3.

7.2 Zero Point Adjustment

Adjust the zero point after operating preparation is completed.

IMPORTANT

Do not turn off the power to the transmitter immediately after a zero adjustment. Powering off within 30 seconds after a zero adjustment will return the adjustment back to the previous settings.

The zero point adjustment can be made in either way: using the zero-adjustment screw of the transmitter or the BT200 operation.

For output signal checking, display the parameter A10: OUTPUT (%) in the BT200.

After reviewing this parameter you are prepared to adjust the zero point. When making the zero adjustment on a pressure transmitter, the process pressure value does not have to be set to the low limit of the measurement range (0%). In such case, adjust the transmitter output signal to the actual measured value obtained from a high-accuracy pressure measuring instrument.

IM 01C21D01-01E

7. OPERATION

7.2.1 When you can obtain Low Range

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

For pressure measurement using gauge pressure transmitters, follow the step below before 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.

 Using the Transmitter Zero-adjustment

Screw

Before adjusting a screw, check that the parameter J20: EXT ZERO ADJ displays ENABLE. See Subsection 8.3.3 (11) for the setting procedure.

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 zero

adjustments varies with the screw turning speed, turn the screw slowly for fine adjustment and quickly for coarse adjustment.

7.2.2 When you cannot obtain Low Range Value from actual measured value of 0%;

Convert the actual measured value obtained by a digital manometer or a glass gauge into %.

7. OPERATION

7.3 Starting Operation

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

1) 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.”

2) 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 and IECEx 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 by hand.

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

7.4 Shutting Down Operation

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 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.

7.5.1 Draining Condensate

1) Gradually open the drain screw or drain plug and

drain the transmitter pressure-detector section. (See Figure 7.5.1.)

2) When all accumulated liquid is completely re-

moved, 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.

Shut down the transmitter operation as follows.

1) Turn off the power.

2) Close the stop valve.

3) Close the tap valve.

NOTE

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

Drain screw

When you loosen the drain screw or drain plug, the accumulated liquid will be expelled in the direction of the arrow.

7.6 Setting the Range Using the

Range-setting Switch

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 3 MPa.

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

indicator then displays “HSET.”

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 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 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 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.”

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.

Integral indicator

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.

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.

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.

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.

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.

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.

Adjustment Method Description

Using the BT200 Set the present input to 0%.

Using the external zero-adjustment screw  P.8-14

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.

Adjust output to the reference value obtained using other means.

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

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.

T0809.EPS

(10) 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

The higher range value is changed keeping the span constant. Parameters C21 and C22 are changed at the same time.

F0826.EPS

Note that changing the higher range value does not cause the lower range value to change but does change the span.

• Example 2: When the higher range value is to be changed to 10 kPa with the

present setting of 0 to 30 kPa, take the following action with an input pressure of 10 kPa applied.

SET H11:AUTO HRV 30 kPa + 30

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.

• 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.

9.4.1 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 and the transmitter’s use in such rated area. Thus 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 9.4.2)

 Removing the Integral Indicator

1) Remove the cover.

9.4.3 Cleaning and Replacing the Capsule Assembly

This subsection describes the procedures for cleaning and replacing the capsule assembly. (See Figure 9.4.3.)

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 Allen screws that fasten the transmitter section and pressure-detector section together.

 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 fluid.

• 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

9.4.2.

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