2.5Pressure Connection

WARNING

•Never loosen the process connector bolts when an instrument is installed in a process. The device is under pressure, and a loss of seal can result in a sudden and uncontrolled release of process fluid.

•When draining toxic process fluids that have condensed inside the pressure detector, take appropriate steps to prevent the contact of such fluids with the skin or eyes and the inhalation of vapors from these fluids.

IM 01C27B01-01EN

<2. Handling Cautions>	2-3

The following precautions must be observed in order to safely operate the transmitter under pressure.

(a)Make sure that all the process connector bolts are tightened firmly.

(b)Makesurethattherearenoleaksintheimpulse piping.

(c)Never apply a pressure higher than the specified maximum working pressure.

2.6Restrictions 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 first observed.

2.7Insulation 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 VAC (100 VAC with an internal lightning protector) for the dielectric strength test.

(c)The procedure for conducting these tests is as follows:

•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 briefly 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

When storing the instrument with a battery pack, it is recommended to put the instrument in Deep Sleep mode to conserve the batteries. For details on how to switch to Deep Sleep mode, refer to subsection 8.3.16 “Switching to Deep Sleep Mode”.

•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 specified voltage.

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

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

Since the H/Llabel 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/Llabel plate to clearly indicate this change.

4.5Rotating 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 confirm 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 configuration of the instrument.) It can be fixed at any angle within above range.

1)Remove the five setscrews that fasten the transmitter section and capsule assembly, using theAllen wrench.

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

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

5.Installing Impulse Piping

5.1Impulse 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 line, or the drain for a gas-filled 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 fluid (gas, liquid, or steam). Pay careful attention to the following points when routing the impulse piping and connecting the impulse piping to a transmitter.

5.1.1Connecting 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.

(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)

A3-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 tightentheballheadlocknuts.(Theball-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 U-bolt nuts

NOTE

Aftercompletingtheconnectionofthetransmitter 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 TapAngles

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.

Pressure	45° 45°		45°	45°
taps
Process		45°	45°
piping
				F0504.ai

Figure 5.4 Process Pressure TapAngle

(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.

(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 fluids in the two lines will cause an error in the measurement pressure. When measuring flow, 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 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

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

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.

5.2Impulse 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 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 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.

•Avariety 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.
