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 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:

• Insulation Resistance Test

1) Remove the battery pack. See subsection 9.4.5 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

1) Remove the battery pack. See subsection 9.4.5 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 10 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.

4.3 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. For the EJX530B whose capsule code is A, B or C, the pipe of the atmospheric opening may interfere with the stopper and disturb further rotation. In that case, screw off the pipe rst, rotate the housing, and then screw in the pipe by hand again.

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.

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 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

IMPORTANT

The transmitter can be installed in horizontal impulse piping conguration, tilting the transmitter's position up to 90°. When tilting, observe that the pipe (for Model EJX530A with measurement span code A, B, and C) is positioned horizontal downwards, or any place between them, as shown in Figure 5.1 The zero-adjustment screw must be positioned downwards for all the models.

F0501.ai

Zero-adjustment screw Pipe

(backside of the instrument)

The pipe (open to atmosphere) is positioned horizontal.

If the zero-adjustment screw is positioned other than downwards after installation, rotate the housing until it is positioned downwards.

Figure 5.1 Horizontal Impulse Piping Connection

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 5.2 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.

Figure 5.2 Process Pressure Tap Angle

(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.

<5. Installing Impulse Piping>

5-2

IM 01C27F01-01EN

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

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 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.

• 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.
