2. HANDLING CAUTIONS

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.

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

: Refer to USER'S MANUAL

F0202.EPS

Figure 2.2 Name Plate

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

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.

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.

IM 01C21C01-01E 2-1

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.

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

2. HANDLING CAUTIONS 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.

(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 M 1 .

4) After completing the test and being very careful not to touch exposed conductors disconnect the insulation tester and connect a 100 k 1 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.

2-2 IM 01C21C01-01E

2. HANDLING CAUTIONS

2) Turn OFF the dielectric strength tester. Then connect the tester between the shorted SUPPLY terminals and the grounding terminal. Be sure to connect the grounding lead of the dielectric strength tester to the ground terminal.

3) Set the current limit on the dielectric strength tester to 10 mA, then turn ON the power and gradually increase the test voltage from ‘0’ to the specified voltage.

4) When the specified voltage is reached, hold it for one minute.

5) After completing this test, slowly decrease the voltage to avoid any voltage surges.

2.9 Installation of Explosion

Protected Type

4.1 Precautions

Before installing the transmitter, read the cautionary notes in Section 2.4, “Selecting the Installation

Location.” For additional information on the ambient conditions allowed at the installation location, refer to

Subsection 10.1 “Standard Specifications.”

IMPORTANT

Please use a gasket which has a bigger inside diameter than that of gasket facing (ød) on diaphragm seal. In case a gasket which has a smaller inside diameter than that of gasket facing is used, it may cause an error as the gasket prevents diaphragm from working correctly. (Refer to Subsection 10.4 ‘Dimensions’)

IMPORTANT

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

• Do not step on this instrument after installation.

• Never loosen the four screws securing the cover flanges (if the seal liquid leaks, the transmitter cannot be used).

4.2 Mounting

The transmitter is mounted on a process using its highpressure side flange as shown in Figure 4.1. The customer should prepare the mating flange, gasket, stud bolts and nuts.

5. INSTALLING IMPULSE PIPING

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.

(2) Tightening the Process Connector Mounting Bolts

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

(3) Removing the Impulse Piping Connecting

Port Dustproof Cap

The impulse piping connecting port of the transmitter is covered with a plastic cap to exclude dust. This cap must be removed before connecting the piping. (Be careful not to damage the threads when removing this cap. Never insert a screwdriver or other tool between the cap and port threads to remove the cap.)

5.1.1 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. For liquid level measurement in an open tank, the ‘L’ (low pressure) side is used to refer atmosphere. For a closed tank, connect the impulse line to the low pressure side of the transmitter. This will refer the pressure in the tank.

5.1.2 Routing the Impulse Piping

(1) 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.

(2) 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.

“ H ” and “ L ” are shown

Low pressure connection

Process connector

Bolt

F0501.EPS

Figure 5.1 “H” and “L” Symbols on a Capsule Assembly

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.

5-1 IM 01C21C01-01E

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.), etc. and make appropriate changes and additions to the connection configurations.

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

When adjusting the transmitter zero point, the liquid level in a tank does not have to be set to the low limit

(0%) of the measuring range. In such case, match the transmitter output signal with the actual measured value using a glass gauge, for example.

7. OPERATION

7.2.1 When you can obtain Low Range

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

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 (12) 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.

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.

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.

7.3 Starting Operation

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

1) Confirm the operating status.

The output signal may widely fluctuate (hunting state) due to process pressure periodic variation. In such case, BT200 operation can dampen the transmitter output signal. Confirm the hunting state 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:

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.

7-3 IM 01C21C01-01E

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 plug and drain the transmitter pressure-detector section. (See Figure

7.5.1.)

2) When all accumulated liquid is completely removed, close the drain plug.

3) Tighten the drain plug to a torque of 34 to 39 N·m.

7.5.2 Venting Gas

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

7.5.1)

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

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

Drain plug

Vent screw

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

7. OPERATION

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.

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.

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.”

7-4 IM 01C21C01-01E

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.

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.

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 (low pressure side open to atmosphere). If the measurement range 0% point is shifted in the negative direction (elevated zero), the reference pressure should be applied on the low pressure side (high pressure side open to atmosphere).

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.

Note: The above table contains the instruments capable of performing calibration to the 0.2% level. Since special maintenance and management procedures involving traceability of each instrument to higher-level standards are required for calibration to the 0.1% level, there are difficulties in calibration to this level in the field. For calibration to the 0.1% level, contact Yokogawa representatives from which the instrument was purchased or the nearest Yokogawa office.

CAUTION

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. MAINTENANCE

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.

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.
