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

2.3 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.
(b) When storing the transmitter, repack it as nearly as possible to the way it was packed when delivered from the factory.
(c) If storing a transmitter that has been used, thoroughly clean the chambers inside the cover flanges, so that no measured fluid remains in it. Also make sure before storing that the pressure-detector and transmitter section are securely mounted.
IM 01C21D01-01E
2.4 Selecting the Installation
Location
The transmitter is designed to withstand severe environmental conditions. However, to ensure stable and accurate operation for years, observe the following precautions when selecting an installation location.
(a) Ambient Temperature
Avoid locations subject to wide temperature variations or a significant temperature gradient.
If the location is exposed to radiant heat from plant equipments, provide adequate thermal insulation and/or ventilation.
(b) Ambient Atmosphere
Avoid installing the transmitter in a corrosive atmosphere. If the transmitter must be installed in a corrosive atmosphere, there must be adequate ventilation as well as measures to prevent intrusion or stagnation of rain water in conduits.
(c) Shock and Vibration
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.
• During draining condensate from the pressure-detector section, take appropriate care to avoid contact with the skin, eyes or body, or inhalation of vapors, if the accumulated process fluid may be toxic or otherwise harmful.
<2. Handling Cautions>
2-2
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.
(c) Never apply a pressure higher than the specified 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 6.7, 6.8 and 6.9.)
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.
IM 01C21D01-01E
(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.
(c) Before conducting these tests, disconnect all signal 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 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.

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 gasfilled 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 5.2 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.

Figure 5.2 Process Pressure Tap Angle
(For Horizontal Piping)
(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
(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 (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 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. Wiring
6.1 Wiring Precautions
IMPORTANT
• Lay wiring as far as possible from electrical noise sources such as large capacity transformers, motors, and power supplies.
• Remove electrical connection dust cap before wiring.
• All threaded parts must be treated with waterproofing sealant. (A non-hardening silicone group sealant is recommended.)
• To prevent noise pickup, do not pass signal and power cables through the same ducts.
• Explosion-protected instruments must be wired in accordance with specific requirements (and, in certain countries, legal regulations) in order to preserve the effectiveness of their explosion-protected 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.
6.2 Selecting the Wiring
Materials
(a) Use stranded leadwires or cables which are the same as or better than 600 V grade PVC insulated wire (JIS C3307) or equivalent.
(b) Use shielded wires in areas that are susceptible to electrical noise.
(c) In areas with higher or lower ambient temperatures, use appropriate wires or cables.
(d) In environment where oils, solvents, corrosive gases or liquids may be present, use wires or cables that are resistant to such substances.
(e) It is recommended that crimp-on solderless terminal lugs (for 4 mm screws) with insulating sleeves be used for leadwire ends.

7. Operation
7.1 Preparation for Starting
Operation
The Model 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, highpressure 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 pressuredetector section.
3) Confirm that there is no pressure leak in the impulse piping, transmitter, or other components.
(b) 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 self-venting, refer to
Subsection 7.5 for instructions.
(c) Turn ON power and connect the BT200.
Open the terminal box cover, and connect the
BT200 to the SUPPLY + and – terminals.
(d) Using the BT200, confirm that the transmitter is operating properly. Check parameter values or change the setpoints as necessary. See
Chapter 8 for BT200 operation.
If the transmitter is equipped with an integral indicator, its indication can be used to confirm that the transmitter is operating properly.

7.2 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
7.2.1 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 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 zero adjustments varies with the screw turning speed, turn the screw slowly for fine adjustment and quickly for coarse adjustment.
Using the BT200
Zero point can be adjusted by simple key operation of the BT200.
Select parameter J10: ZERO ADJ, and press the
ENTER key twice. The zero point will be adjusted automatically to the output signal 0% (4 mA DC).
Confirm that the setting value displayed for the parameter is ‘0.0%’ before pressing the ENTER key. See Subsection 8.3.3 (11) for BT200 operating procedures.

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. Operation>
7.4 Shutting Down Operation
Shut down the transmitter operation as follows.
1) Turn off the power.
2) Close the stop valve.
3) Close the tap valves.
7-4
NOTE
Whenever shutting down the transmitter for a long period, remove any process fluid from the transmitter pressure-detector section.
7.5 Venting or Draining
Transmitter Pressuredetector Section
Since this transmitter is designed to be selfdraining and self-venting with vertical impulse piping connections, neither draining nor venting will be required if the impulse piping is configured appropriately for self-draining 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.
IM 01C21D01-01E
7.5.1 Draining Condensate
1) Gradually open the drain screw or drain plug and drain the transmitter pressure-detector section. (See Figure 7.2)
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.
Drain plug
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 zero-adjustment 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.
1) Connect the transmitter and apparatus as shown in Figure 9.1 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.
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.”
IM 01C21D01-01E
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.

Precautions
8.1.1 Connecting the BT200
The transmitter and the BT200 can be connected either to the BT200 connection hooks in the transmitter terminal box or to a relaying terminal board.
• Note for Connecting the BT200
IMPORTANT
• Analog output may change temporally in connecting with BRAIN terminal due to an initial current flowed to it. To prevent communication signal affecting the upper system, it is recommended to install a lowpass filter (approximately 0.1s).
• Communication signal is superimposed on analog output signal. It is recommended to set a low-pass filter (approximately
0.1s) to the receiver in order to reduce the output effect from communication signal.
Before online-communication, confirm that communication signal does not give effect on the upper system.

Description
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.
Change the range of normal output.
Sets the following 5 types of integral indicator scale ranges and units:
% scale indicator, user set scale indicator, alternate indication of user set scale and
% scale, input pressure display, alternate indication of input pressure and % scale
When using the user set scale, 4 types of data can be set:
user set scale setting, unit (BT200 only), display value at 4 mA DC (LRV), and display value at 20 mA DC (HRV).
Note: LRV and HRV can be specified with range value specifications up to 5 digits (excluding any decimal point) within the range of –19999 to 19999.

Reverses the direction for 4 to 20 mA DC output relative to input.
Reverse mode is used for applications in which safety requires that output be driven toward 20 mA if input is lost.
Displays the status of 4 to 20 mA DC output when a CPU failure. The parameter of the standard unit is fixed to the high limit value.
Sets the status of the 4 to 20 mA DC output when an abnormal status is detected with the capsule or the amplifier as the result of self-diagnosis. One of the following statuses; last held, high limit, and low limit values, can be selected.
Range for 4 to 20 mA DC signal is set with actual input applied. Sets 20 mA DC output precisely with respect to user’s reference instrument output. Note that DPharp is calibrated with high accuracy before shipment, so span should be set using the normal range setup.
Adjusts zero point. This can be done either using the external zero-adjustment screw on the transmitteror using the BT200.
Adjust the characterization curve. All the transmitters are calibrated at factory and this adjustment is normally not necessary for most cases. Use for specific purposes.
Used for loop checks.
Output can be set freely from –5% to 110% in 1% steps.
Allows user to enter up to 5 items of any desired text in up to 8 uppercase alphanumeric characters per item.

Description
Set the present input to 0%.
Adjust for 0% output at input level of

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

(13) Span Adjustment
Each DPharp EJA series transmitter is factory characterized according to the specification.
Mounting position effects or zero shifts caused by static pressure are typically compensated by a zero adjustment.
A span adjustment is a function to correct the slope error from a zero point in characterizing 100% point
(HRV). This function can be used when span drifts may be caused or characterization to the specific pressure standard is required.
Therefore, the zero point adjustment should always be performed before the upper point adjustment in order to maintain the pitch between zero and 100% points within the calibration range.
You can manually perform the trimming procedure by using J15: SPAN ADJ.
• Span adjustment value
The span adjustment value is calculated as follows.

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. Maintenance>
9-1
9.2 Calibration Instruments
Selection
Table 9.1 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 9.1 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.
• Do not perform the calibration procedures until the transmitter is at room temperature.
2) Apply reference pressures of 0%, 50%, and 100% of the measurement range to the transmitter. Calculate the errors (differences between digital voltmeter readings and reference pressures) as the pressure is increased from 0% to 100% and is decreased from 100% to 0%, and confirm that the errors are within the required accuracy.

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)
Removing the Integral Indicator
1) Remove the cover.
2) Supporting the integral indicator by hand, loosen its two mounting screws.
3) Dismount the LCD board assembly from the

9.4.3 Cleaning and Replacing the Capsule
Assembly
This subsection describes the procedures for cleaning and replacing the capsule assembly. (See
Figure 9.5.)
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 and dry thoroughly 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.
3) Separate the transmitter section and pressuredetector section.
