specied maximum working pressure.

2.6 Restrictions on Use of Radio Transceivers

IMPORTANT

Although the transmitter has been designed to resist high frequency electrical noise, if a radio transceiver is used near the transmitter or its external wiring, the transmitter may be affected by high frequency noise pickup. To test this, start out from a distance of several meters and slowly approach the transmitter with the transceiver while observing the measurement loop for noise effects. Thereafter use the transceiver outside the range where the noise effects were rst observed.

2.7 Insulation Resistance and

• Insulation Resistance Test

1) Remove the battery pack. See subsection 9.4.6 for details on how to remove it.

2) Short-circuit the battery connection terminals in the terminal box.

3) Turn OFF the insulation tester. Then connect the insulation tester plus (+) lead wire to the shorted battery connection terminals and the minus (–) leadwire to the grounding terminal.

4) Turn ON the insulation tester power and measure the insulation resistance. The voltage should be applied as briey as possible to verify that the insulation resistance is at least 20 MΩ.

5) 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 battery connection terminals. Leave this resistor connected at least one second to discharge any static potential. Do not touch the terminals while it is discharging.

NOTE

Dielectric Strength Test

Since the transmitter has undergone insulation resistance and dielectric strength tests at the factory before shipment, normally these tests are not required. If the need arises to conduct these tests, heed the following:

(a) Do not perform such tests more frequently than

is absolutely necessary. Even test voltages that do not cause visible damage to the insulation may degrade the insulation and reduce safety margins.

(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.

follows:

• Dielectric Strength Test

1) Remove the battery pack. See subsection 9.4.6 for details on how to remove it.

2) Short-circuit the battery connection terminals in the terminal box.

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

4) Set the current limit on the dielectric strength tester to 0.1 mA, then turn ON the power and gradually increase the test voltage from ‘0’ to the specied voltage.

5) When the specied voltage is reached, hold it for one minute.

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

4.4 Swapping the High/Lowpressure Side Connection

IMPORTANT

This section is applicable only for EJX110B differential transmitters, and not applicable for gauge or absolute pressure transmitters.

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 eld after making the change.

1) Use an Allen wrench (JIS B4648, nominal 2.5 mm) to remove the ve setscrews 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 ve setscrews to x the pressuredetector section and transmitter section together (at a torque of 1.5 N·m).

Reposition the process connector and drain

(vent) plugs to the opposite side as described in subsection 4.3.

4.5 Rotating Transmitter Section

WARNING

Intrinsic safe type transmitters must be, as a rule, do not rotate transmitter section if it is powered. In case you need to rotate when the transmitter is powered, using gas detector and conrm no existence of explosive gas before rotating.

The transmitter section can be rotated approximately 360° (180° to either direction or 360° to one direction from the original position at shipment, depending on the conguration of the instrument.) It can be xed at any angle within above range.

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

2) Rotate the transmitter section slowly and stop it at designated position.

3) Tighten the ve setscrews to a torque of 1.5 N·m.

IMPORTANT

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

Since the H/L label plate on the capsule assembly will remain unchanged, use this function only when you cannot switch the impulse piping. If the ‘H/L_SWAP’ parameter setting is changed, the input/output relationship is reversed as shown in Figure 4.6; be sure this is understood by all. After reversing the setting, modify the H/L label plate to clearly indicate this change.

5.1 Impulse Piping Installation Precautions

The impulse piping that connects the process outputs to the transmitter must convey the process pressure accurately. If, for example, gas collects in a liquid-lled impulse line, or the drain for a gas-lled impulse line becomes plugged, it will not convey the pressure accurately. Since this will cause errors in the measurement output, select the proper piping method for the process uid (gas, liquid, or steam). Pay careful attention to the following points when routing the impulse piping and connecting the impulse piping to a transmitter.

5.1.1 Connecting Impulse Piping to a Transmitter

(1) Check the High and Low Pressure

Connections on the Transmitter (Figure 5.1)

Symbols “H” and “L” have been placed on the capsule assembly to indicate high and low pressure side. With differential pressure transmitters, connect the high pressure side impulse line to the “H” side, and the low pressure side impulse line to the “L” side.

“H” and “L” are shown

(2) Changing the Process Connector Piping

Connections (Figure 4.1) (for differential pressure transmitters)

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 an impulse line with a process connectors.

(3) Tightening the Process Connector

Mounting Bolts

After connecting an impulse line, tighten the process connector mounting bolts uniformly. (Apply a torque of 39~49N·m {4~5kgf·m})

(4) Removing the Impulse Piping Connecting

Port Dustproof Cap

The impulse piping and a 3-valve manifold connecting port on the transmitter is covered with a plastic cap to keep out dust. This cap must be removed before connecting the line. (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) Connecting the Transmitter and 3-

Valve Manifold (for differential pressure transmitters)

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 3-valve manifold types: 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.

 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 (2-

inch) 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:

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 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 gure 5.4 according to the kind of uid being measured.

NOTE

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

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

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

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

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

[Steam][Liquid]

(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

Lines (for differential pressure transmitters)

If there is a temperature difference between the high and low impulse lines, the density difference of the uids in the two lines will cause an error in the measurement pressure. When measuring ow, impulse lines must be routed together so that there is no temperature difference between them.

(5) Condensate Pots for Steam Flow

Measurement (for differential pressure transmitters)

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 uid 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 ow.

(6) Preventing Wind Speed Effects in Very Low

Differential Pressure Measurement (for differential pressure transmitters)

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 an impulse line to the low pressure side and insert its end into a windexcluding pot (cylindrical with a base plate).

(7) Preventing Freezing

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

IM 01C27B01-01EN

<5. Installing Impulse Piping>

5-4

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 and 5.6 show examples of typical impulse piping connections. Before connecting the transmitter to the process, study the transmitter installation location, the process piping layout, and the characteristics of the process uid (corrosiveness, toxicity, ammability, etc.), in order to make appropriate changes and additions to the connection congurations.

Note the following points when referring to these piping examples.

• 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 conguration in which the direction of connection is either upwards or downwards.

• If the impulse line is long, bracing or supports should be provided to prevent vibration.

• The impulse piping material used must be compatible with the process pressure, temperature, and other conditions.

• A variety of process pressure tap valves (main valves) are available according to the type of connection (anged, screwed, welded), construction (globe, gate, or ball valve), temperature and pressure. Select the type of valve most appropriate for the application.

6.1 Mounting Antenna and Wiring

For Amplier housing code 8 and 9, an antenna is not attached to the transmitter. The following provides the instructions for mounting the antenna and installing the remote antenna and wiring using antenna extension cable.

IMPORTANT

6-1

The antenna connector is covered with a cap at the time of delivery. Keep the cap attached until the installation of the antenna or antenna cables to protect the inside connection part. The unscrewed cap should be stored in order to replace it immediately after the antenna or antenna cables are removed.

CAUTION

To maintain the ultimate conditions of radiofrequency signal, protect the connectors of antenna, extension antenna cable, and arrester from the corrosive atmosphere by the following treatment.

1. Clean the connection to be protected.

2. Wind the butyl rubber self-bonding tape around the connection. See the manual of the tape about the winding.

3. To protect the butyl rubber self-bonding tape from the environment such as ultraviolet rays and so on, wind vinyl tape (or a vinyl type self-bonding tape) on it.
