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 01C21B01-01E
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.
The following precautions must be observed in order to safely operate the transmitter under pressure.
<2. Handling Cautions>
2-2
(a) Make sure that the four 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.
CAUTION
Maximum working pressure of the model
EJA120A differential pressure transmitter is 50 kPa {0.5 kgf/cm 2 }.
Should the pressure exceed 50 kPa {0.5 kgf/ cm 2 }, it is possible to break the sensor. Proceed with caution when applying 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.
IM 01C21B01-01E
(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.
(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.

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 a Allen wrench (JIS B4648, nominal 5 mm) to remove the two Allen screws 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 Allen screws to fix the pressuredetector section and transmitter section together (at a torque of 5 N·m).
IMPORTANT
Do not rotate the pressure-detector section more than 180°.

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-filled 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) Check the High and Low Pressure
Connections on the Transmitter (Figure 5.1)
Symbols “H” and “L” are shown on a capsule assembly to indicate high and low pressure side.
Connect the impulse piping to the “H” side, and the low impulse piping to the “L” side.

(2) Changing the Process Connector Piping
Connections (Figure 4.1)
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 the impulse piping with the process connectors when connecting the piping.
(3) Tightening the Process Connector
Mounting Bolts
After connecting the impulse piping, tighten the process connector mounting bolts uniformly.
(4) Connecting the Transmitter and 3-Valve
Manifold
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 types of 3-valve manifold: 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.
IM 01C21B01-01E
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 (2inch) 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 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

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 strictly 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.
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.

(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.
<5. Installing Impulse Piping>
5-3
(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) Temperature Difference Between Impulse
Piping
If there is a temperature difference between the high and low impulse piping, the density difference of the fluids in the two lines will cause an error in the measurement pressure. When measuring flow, impulse piping must be routed together so that there is no temperature difference between them.
(5) Condensate Pots for Steam Flow
Measurement
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.
(6) Preventing Wind Speed Effects in Very Low
Differential Pressure Measurement
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 a impulse piping to the low pressure side and insert its end into a windexcluding pot (cylindrical with a base plate).
IM 01C21B01-01E
(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.
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 5.5 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 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 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 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 EJA110A, EJA120A and EJA130A pressure transmitter measures the flow rates and the pressure of liquids, gases, and steam, and also liquid levels. This section describes the operation procedure for the EJA110A as shown in Figure
7.1 (vertical impulse piping type, high-pressure connection: right side) when measuring a liquid flow rate.
NOTE
Check that the process pressure tap valves, drain valves, and 3-valve manifold stop valves on both 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.
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.
<7. Operation>
7-1
(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. Leave the equalizing valve open even after venting gas.
(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.

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 BT200 to dampen the transmitter output signal. Confirm the hunting using a receiving instrument or the integral indicator, and set the optimum damping time constant. See
Subsection 8.3.3 (3), “Damping Time Constant
Setup.”
4) After confirming the operating status, perform the following.
<7. Operation>
7-3
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
Shut down the transmitter operation as follows.
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 from the transmitter pressure-detector section.
• The equalizing valve must be left OPEN.
IM 01C21B01-01E
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.
<7. Operation>
7-4
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.

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.”
<7. Operation>
7-5
IMPORTANT
• Do not turn off the power to the transmitter immediately after completion of the change in the LRV and/or HRV setting(s). Note that powering off within thirty seconds after setting will cause a return to the previous settings.
• Changing LRV automatically changes HRV to the following value.
HRV = previous HRV + (new LRV – previous LRV)
• If the range-setting push-button and external zero-adjustment screw are not touched during a range-change operation, the transmitter automatically switches back to the normal operation mode.

• Note 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).
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 at amplifier.
Can be set in 9 increments from 0.2 to 64 s.
Sets modes for output signal and integral indicator to “Linear mode” (proportional to input differential pressure) or to “Square root mode” (proportional to flow).
Used mainly to stabilize output near 0% if output signal is the square root mode.
Two modes are available: forcing output to 0% for input below a specific value, or changing to proportional output for input below a specific value.
Change the range of normal output.

Description
Available from the following 5 types of integral indicator scale ranges and units:
input pressure, % of range, user set scale, input static pressure, % of static pressure range, and alternating among any four of the above.
When using the user set scale, 4 types of data should be configurated in advance:
user set scale setting, unit (BT200 only), display value at 4 mA DC (LRV), and display value at 20 mA DC (URV).
Note: LRV and URV can be specified with range value specifications up to 5 digits (excluding any decimal point) within the range of –32000 to 32000.
Sets a unit for temperatures displayed on the BT200.
Sets a unit for static pressure displayed on the BT200.
Reverses the direction for 4 to 20 mA DC output relative to input.
Reverse mode is used for applications in which safety requires that output be driven toward 20 mA if input is lost.
Used where installation conditions make it imperative to connect high pressure side impulse line to low pressure side of transmitter. Reversal of orientation should be dealt with by reversing impulse line wherever possible. Use this function only where there is no alternative.
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.
Used to measure bi-directional flows.
Output at zero flow is 12 mA DC, with output range equally divided between forward and reverse flow.
Can be used with square root mode.
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.

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.

This is set to “ENABLE” when the instrument is shipped.
<8. BRAIN TERMINAL BT200 Operation>
8-17
• Zero point adjustment using external zeroadjustment screw on the transmitter
Turn the zero-adjustment screw on the outside of the transmitter case using a slotted screwdriver.
Turn the screw to the right to increase the zero point or to the left to decrease the zero output; the zero adjusts in increments of 0.01% of the range setting.
Note that the amount of adjustment to the zero point changes according to the speed at which the screw is turned. To make fine adjustments, turn the screw slowly; to make coarse adjustments, turn the screw quickly.
Note: When a zero point adjustment has been made, do not turn off the transmitter less than 30 seconds after adjustment.
(17) 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.

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 vacuumpump.
• 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.

Precautions for CENELEC and IECEx
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 flameproof 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.

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)
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
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.
IM 01C21B01-01E
Attaching the Integral Indicator
Integral indicator can be installed in the following three directions.

4) Use a socket driver (width across flats, 5.5mm) to loosen the two bosses.
5) Carefully pull the CPU assembly straight forward to remove it.
6) Disconnect the flat cable (cable with black 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 flat cable (with black connector) between the CPU assembly and the capsule.
2) Connect the output terminal cable (with brown connector).
NOTE
Make certain that the cables are free of pinching between the case and the CPU assembly edge.
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.
4) Tighten the two bosses. If the transmitter is equipped with an integral indicator, refer to
Subsection 9.4.1 to mount the indicator.
NOTE
Confirm 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.

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.
