Installation

Step 2

Flow direction

Process fluid

Orientation

Keys for sensor orientation

The sensor will function properly in any orientation if the sensor flow tubes remain filled with process fluid.

Micro Motion sensors measure accurately regardless of flow direction as long as the sensor flow tubes remain filled with process fluid.

Flow direction arrow

The sensor has a flow direction arrow (see illustrations, pages 3-6) to

help you configure the transmitter for flow direction. Process fluid flowing in the direction opposite to the flow direction arrow may cause unexpected transmitter output unless the transmitter is configured appropriately. For instructions on configuring the transmitter’s flow direction parameter, refer to the transmitter instruction manual.

Vertical pipeline

If the sensor is installed in a vertical pipeline, liquids and slurries should flow upward through the sensor. Gases may flow upward or downward.

Typical sensor orientations are shown in the tables on the following pages:

• For measuring liquids, see page 14.

• For measuring gases, see page 15.

• For measuring slurries, see page 16.

Mounting continued

Conduit openings

Optional Model D600 mounting

If possible, install wiring with the conduit openings pointed downward to reduce the risk of condensation or excessive moisture in the housing.

Otherwise, install drip legs on the cable or conduit.

When installing a Model D600 in a high-vibration area, additional support may be added if desired. Use the D600 snub-mount connector with vibration isolator to help support the sensor. See illustration, below.

Typically, the snub-mount connector is used when the D600 is installed in the flag-mount orientation (in a vertical pipeline), as shown below.

Model D600 mounting with snub-mount connector

D600 in flag-mount orientation can use snub connector for added support in high-vibration installations

The following warning applies to hazardous area installations

WARNING

Failure to comply with requirements for intrinsic safety in a hazardous area could result in an explosion.

• Make sure the hazardous area specified on the sensor approvals tag is suitable for the environment in which the

sensor is installed. See illustrations, pages 3-6.

• For installation in an area that requires intrinsic safety, refer to Micro Motion hazardous approval installation instructions.

• For hazardous area installations in Europe, refer to standard EN 60079-14 if national standards do not apply.

Most Model D sensors are shipped with a junction box for wiring. There are two types of junction boxes: one for the D600 sensor, one for all the other D sensors.

• The D600 junction box is different than the junction box for other D sensors. D600 sensors are also available with a core processor. For

more information on the D600 sensor, see page 24.

• Model DT sensors can use a junction box. For more information on the

DT sensor junction box, see page 20.

For Model D sensors (except the DT series and D600):

• If it if not already installed, install the junction box on the sensor, following the wiring instructions on the junction box.

• If possible, install wiring with the junction-box opening pointed downward, or with a drip leg in the conduit or cable, to reduce the risk of condensation or excessive moisture in the junction box. See

illustration on page 20.

• Next, follow the guidelines in Connecting and shielding 9-wire cable to

wire the sensor to the transmitter.

Both cable types contain shield drain wires. You may also use jacketed cable with conduit.

Cable connections to sensor and transmitter

The wiring procedure is the same for the sensor and transmitter. Refer to the wiring diagrams on the following pages, and follow these steps:

CAUTION

Failure to seal the sensor and transmitter housings could cause a short circuit, which would result in measurement error or flowmeter failure.

• Ensure integrity of gaskets and O-rings.

• Grease all O-rings before sealing.

• Install drip legs in cable or conduit.

• Seal all conduit openings.


Wiring continued

1. Locate the wires by color and terminal number.

2. Insert the stripped ends of the individual wires into the terminal blocks. No bare wires should remain exposed.

• At the sensor, connect wiring inside the junction box.

• At the transmitter, connect wiring to the transmitter’s intrinsically safe terminals for sensor wiring.

3. Tighten the screws to hold the wires in place.

4. Ensure integrity of gaskets, then tightly close and seal the junction-box cover and all housing covers on the transmitter.

CAUTION

Drain wires from a 9-wire cable must be clipped at the sensor end and insulated with heat-shrink wrapping.

Failure to properly terminate drain wires will cause sensor error.

D600 sensor For wiring between the sensor and transmitter, there are two options: junction box or core processor.

• For wiring instructions from junction box to transmitter, see page 29.

• For wiring from core processor to transmitter or for direct host, see

page 32.

The D600 also requires wiring to an AC power supply for the integral and remote version of the booster amplifier. Between 85-250 VAC of power

must be provided. See pages 26-27.

The remote version of the booster amplifier requires wiring to the sensor

and wiring of the drive wires. See page 28.

The sensor is shipped with 16 feet (5 meters) of 9-wire cable for connecting from the remote booster amplifier to the intrinsically safe junction box located on the sensor. For longer cable lengths, up to 60 feet (20 meters), contact Micro Motion.

CAUTION

Improper installation of wiring could cause measurement error or sensor failure.

• Shut off power before installing power-supply wiring.

• Follow all instructions to ensure sensor will operate correctly.

Core processor to a 4-wire remote transmitter or remote host

To connect wiring at the core processor:

1. Use one of the following methods to shield the wiring from the core processor to the remote transmitter:

• If you are installing unshielded wiring in continuous metallic conduit that provides 360° termination shielding for the enclosed wiring, go

to Step 6, page 35.

• If you are installing user-supplied cable gland with shielded cable or armored cable, terminate the shields in the cable gland. Terminate both the armored braid and the shield drain wires in the cable gland.

• If you are installing a Micro Motion-supplied cable gland at the core processor housing:

- Prepare the cable and apply shielded heat shrink as described below. The shielded heat shrink provides a shield termination suitable for use in the gland when using cable whose shield

consists of foil and not a braid. Proceed to Step 2.

32 Micro Motion

Wiring continued

- With armored cable, where the shield consists of braid, prepare the cable as described below, but do not apply heat shrink. Proceed to

Step 2.

2. Remove the cover from the core processor.

4. For connection at the core processor housing, prepare shielded cable

as follows (for armored cable, omit steps d, e, f, and g):

a. Strip 4 1/2 inches (114 mm) of cable jacket.

b. Remove the clear wrap that is inside the cable jacket, and remove the filler material between the wires.

c. Remove the foil shield that is around the insulated wires, leaving

3/4 inch (19 mm) of foil or braid and drain wires exposed, and separate the wires.

d. Wrap the shield drain wire(s) around the exposed foil twice. Cut off the excess wire.

Shield drain wire(s) wrapped twice around exposed shield foil e. Place the EMI-shielded heat shrink over the exposed shield drain wire(s). The tubing should completely cover the drain wires.

f. Without burning the cable, apply heat (250 °F or 120 °C) to shrink the tubing.


Wiring continued

Shielded heat shrink completely covers exposed drain wires g. Position gland clamping insert so the interior end is flush with the heat shrink.

h. Fold the cloth shield or braid and drain wires over the clamping insert and approximately 1/8 inch (3 mm) past the O-ring.

i. Install the gland body into the core processor housing conduit opening.

34

5. Insert the wires through the gland body and assemble the gland by tightening the gland nut.

6. Identify the wires in the 4-wire cable. The 4-wire cable supplied by

Micro Motion consists of one pair of 18 AWG (0,75 mm 2 ) wires (red and black), which should be used for the VDC connection, and one pair of 22 AWG (0,35 mm 2 ) wire (green and white), which should be used for the RS-485 connection. Connect the four wires to the numbered slots on the core processor, matching corresponding numbered terminals on the transmitter.

• If you are connecting to an MVDSolo with MVD Direct Connect ™ I.S. barrier supplied by Micro Motion, the barrier supplies power to the core processor. Refer to the barrier documentation to identify the terminals at the barrier.

• If you are connecting to an MVDSolo without I.S. barrier:

- Connect the VDC wires from the core processor (see figure on

page 36) to an independent power supply. This power supply must

connect only to the core processor. A recommended power supply is the SDN series of 24-VDC power supplies manufactured by

Sola/Hevi-Duty.

- Do not ground either connection of the power supply.

- Connect the RS-485 wires from the core processor (see figure below) to the RS-485 terminals at the remote host. Refer to the vendor documentation to identify the terminals.

CAUTION

Improper grounding could cause measurement error.

To reduce the risk of measurement error:

• Ground the flowmeter to earth, or follow ground network requirements for the facility.

• For installation in an area that requires intrinsic safety, refer to Micro Motion hazardous approval documentation, shipped with the sensor or available from the Micro

Motion web site.


The sensor can be grounded via the piping if the joints in the pipeline are ground-bonded. If the sensor is not grounded via the piping, connect a ground wire to the internal or external grounding screw, which is located on the core processor or junction box.

If national standards are not in effect, follow these guidelines:

• Use copper wire, 14 AWG (2,5 mm 2 ) or larger wire size for grounding.

• Keep all ground leads as short as possible, less than 1 ohm impedance.

• Connect ground leads directly to earth, or follow plant standards.

Refer to the transmitter documentation for instructions on grounding the transmitter.

Startup

Zeroing

Configuration, calibration, and characterization

After the flowmeter has been fully installed, you must perform the zeroing procedure. Flowmeter zeroing establishes flowmeter response to zero flow and sets a baseline for flow measurement. Refer to the transmitter instruction manual for information on performing the zeroing procedure.

You can use the transmitter to configure, calibrate, and characterize the meter. For more information, refer to the transmitter instruction manuals.

The following information explains the difference between configuration, calibration, and characterization. Certain parameters might require

configuration even when calibration is not necessary.

Configuration parameters include such items as flowmeter tag, measurement units, flow direction, damping values, and slug flow parameters. If requested at time of order, the meter is configured at the factory according to customer specifications.

Calibration accounts for the flowmeter’s sensitivity to flow, density, and temperature. Calibration is done at the factory.

Characterization is the process of entering calibration factors for flow, density, and temperature directly into transmitter memory, instead of performing field calibration procedures. Calibration factors can be found on the sensor serial number tag and on the certificate that is shipped with the sensor.

For instructions about flowmeter configuration, calibration, and characterization, see the manual that was shipped with the transmitter.

If the sensor and transmitter are ordered together as a Coriolis flowmeter, the factory has characterized the meter — no additional characterization is necessary. If either the sensor or transmitter is replaced, characterization is required.

Troubleshooting at the transmitter

The tables in the preceding sections refer you to this section for instructions on troubleshooting at the transmitter. To troubleshoot at the transmitter, you might need a digital multimeter (DMM) or similar device, the transmitter display, if it has one, and one of the following:

• HART Communicator

• ProLink or ProLink II software

• AMS software

• Modbus master controller (RFT9739 only, Series 1000, or Series 2000)

• Fieldbus host controller (Series 1000, or Series 2000)

• Profibus host controller (Series 1000 or 2000)

Checking or changing the flow units

Check or change the flow units (units of measure) configuration at the transmitter. If necessary, refer to the instruction manual (or on-line help for software) for the method you choose.

• Use the transmitter display, if it has one

• Use a HART Communicator, ProLink software, or AMS software

• Use a Modbus, fieldbus, or Profibus-PA host controller

Make sure the configured units of measure are the ones you want. Also, make sure you know what the abbreviations mean. For example, g/sec is grams per second, not gallons per second.

46 Micro Motion

Checking for erratic flow rate at the transmitter

Before troubleshooting erratic flow rate, you must first determine whether it is a result of the transmitter or a connected output device.

Check for an erratic flow signal at the transmitter using any of the following methods. If necessary, refer to the instruction manual (or on-line help for software) for the method you choose.



• Use a Modbus, fieldbus, or Profibus-PA host controller

• Use a DMM on the transmitter’s 4-20 mA or frequency output terminals

If the flow rate or output signal is not erratic at the transmitter outputs, the problem is not with the transmitter.

Checking for faulty output wiring

Having already checked the output at the transmitter end (above), use a

DMM to check the signal at the other end (the receiving end) of the output wiring. If the signal is not erratic, the problem is not with the output wiring.

Checking for faulty flowmeter wiring

Wiring problems are often incorrectly diagnosed as a faulty sensor.

Examine wiring between the sensor and transmitter as follows:

1. Check the cable preparation. The flowmeter cable must be prepared correctly. The most common problem is improperly prepared drain wires. See illustration, below. The drains are clipped at the sensor end. They should not be connected to any terminals in the

sensor junction box. See wiring diagrams, pages 22-32.

2. Check wire terminations. Check to be sure wires are secured tightly in the terminal blocks, and making good connections. Make sure no wires remain exposed at either end of the flowmeter cable.

3. Check ohm levels. If the cable was properly prepared and terminal connections are good, check resistance across wire pairs to determine whether the flowmeter cable is faulty. The procedure is performed first at the transmitter, then at the sensor. Follow these steps: a. Disconnect the transmitter’s power supply.

b. Disconnect sensor wiring from the transmitter’s flowmeter terminals.


Troubleshooting continued c. Use a DMM to measure resistance across wire pairs at the

transmitter end of the cable. See table on page 48.

• If the measured value is within the range listed in the table, reconnect wiring and restore power to the transmitter.

• If the measured resistance is outside the range listed in the table, repeat the measurements at the sensor junction box.

- If the sensor is a not a D600, refer to the “Nominal resistance ranges” table below.

- If the sensor is a D600, refer to the table and illustration on

page 49.

- If resistance values measured at the sensor are also outside the range listed in the table, the sensor might be faulty.

Checking the calibration factors

Check or change the flow, density, or temperature calibration factors at the transmitter. The temperature cal factor is for the RFT9739, Model

1700, Model 2700, Model 3500, and 3700 only. If necessary, refer to the instruction manual (or on-line help for software) for the method you choose.

• Use the Model 3500 or 3700 display

• Use a HART Communicator, ProLink or ProLink II software, or AMS software

• Use the host controller

Enter the calibration factors that are listed on the flowmeter calibration tag. (Calibration factors are also listed on the certificate that was shipped with the meter.) If the calibration factors at the flowmeter are already correct, the problem is not with the calibration factors.

Checking the damping value

Check or change the damping value at the transmitter. If necessary, refer to the instruction manual (or on-line help for software) for the method you choose.

• Use the Model 3500 or 3700 display



In almost all applications, the damping value should be greater than or equal to 0.8 seconds. If the damping value is already greater than or equal to 0.8 seconds, the problem is probably not with the damping value.

Damping values less than 0.8 seconds are used in very few applications.

After troubleshooting is complete, if you have a question about whether your application might require a lower damping value, contact the Micro

Motion Customer Service Department. Phone numbers are listed on

page 41. The two most common applications affected by a damping

value that is too high are:

• Very short batching applications

• Very short-pass proving applications

Checking the drive gain

Contact Micro Motion to check the drive gain. Phone numbers are listed

on page 41.

If the transmitter is a Model 1700, 2700, 3500, or 3700, you can use the display to view drive gain. For more information, refer to the manual that is shipped with the transmitter.

Checking the density or temperature reading

View the flowmeter density or temperature measurement in any of several ways:


• Use a HART Communicator, ProLink or ProLink II software, or AMS software

• Use the connected output device, if there is one

Micro Motion

If necessary, test the process fluid to confirm the flowmeter measurement is correct.

Checking for RF or transient-voltage interference

Radio-frequency (RF) or transient-voltage interference can affect the input or output signals at the transmitter. If you suspect interference, and can eliminate the source, do so before checking the alternatives described below.

Output wiring. Output wiring can be affected by interference. Make sure output wiring from the transmitter is properly grounded in accordance with the instructions in the transmitter manual. Also make sure no wires remain exposed at either end of output wiring.

Flowmeter cable. If the flowmeter cable does not have an external shield (see illustration, below), and is not installed in conduit, it could be affected by interference. Also make sure no wires remain exposed at either end of the flowmeter cable.

Troubleshooting at the sensor The tables in the preceding sections refer you to this section for instructions on troubleshooting at the sensor. To troubleshoot at the sensor, you might need a digital multimeter (DMM) or similar device. For some procedures, you might also need the transmitter manual.

Checking flowmeter grounding

The sensor can be grounded via the piping, as long as joints in the pipeline are ground-bonded, or by means of a ground screw on the sensor case. See illustration, below. Transmitter grounding is described in the transmitter instruction manual.

If the sensor is not grounded via the piping, and if national standards are not in effect, adhere to these guidelines to ground the sensor via the junction box:

• Use copper wire, 14 AWG (2,5 mm 2 ) or larger wire size for grounding.

• Keep all ground leads as short as possible, less than 1 ohm impedance.

• Connect ground leads directly to earth, or follow plant standards.

Model D600 sensors

For hazardous area installation in Europe, use standard EN 60079-14 as a guideline if national standards are not in effect.

Checking for moisture in the core processor or sensor junction box

Note that the following will help reduce the risk of getting moisture in the core processor or sensor junction box: If possible, install wiring with the conduit openings pointed down to reduce the risk of condensation or moisture in the housing. Otherwise, install drip legs on the cable or conduit.

All wiring compartments must be sealed to prevent a short circuit. A short would result in measurement error or flowmeter failure.

• The D600 has a junction box and a booster amplifier housing.

• Do not open the D600 booster amplifier housing while the booster amplifier is energized. See the warning statement below.

• Replace all covers and seal all openings before applying power to a

D600 sensor.

WARNING

Explosion Hazard




Micro Motion

®



Open the junction box (and, for a D600, the booster amplifier housing) to check for moisture. If moisture is present, dry out the junction box. Do not use contact cleaner. Follow these guidelines to avoid risk of condensation or excessive moisture from accumulating:



• If possible, install wiring with junction-box openings pointed down.

• Check integrity of gaskets.

• Close and fully seal all housing covers.

Checking for mounting stress on the sensor

Because each installation is unique, it is not possible to offer a definitive solution for mounting problems. However, mounting stresses can be caused by one or more of the following conditions:

• The pipeline is being supported by (hung from) the sensor.

• Misaligned piping was drawn together by the sensor.

• An unsupported pipeline is not sturdy enough to support the sensor.

If you are unable to determine whether the process connections are being subjected to mounting stress, contact Micro Motion for additional

assistance. Phone numbers are listed on page 41.

Checking for vibration and crosstalk

Micro Motion sensors have been designed to minimize the effect of vibration. In very rare cases, however, vibration or crosstalk can affect flowmeter operation. Crosstalk is the transfer of resonant vibration from one sensor to another, and sometimes occurs when two like-size sensors are installed in close proximity to each other and are operating on the same fluid for short periods of time.

Micro Motion meters are rarely affected by vibration, so vibration or crosstalk is probably not the problem. If you are not sure whether vibration or crosstalk is affecting the sensor, contact Micro Motion for

additional assistance. Phone numbers are listed on page 41.

Checking for 2-phase flow

Two-phase flow occurs when air or gas is present in a liquid process stream, or when liquid is present in a gas process stream. Two-phase flow has several causes, as described below.

Leaks. Leaks can occur at process connections, valve seals, and pump seals, resulting in air being introduced into a liquid stream. Air might also be drawn in at the system inlet. Check the system for leaks, and repair any leaks that are found.

Cavitation and flashing. Cavitation and flashing are caused by operating the system at or near the process fluid vapor pressure, resulting in pockets of air or gas being introduced into the process fluid.

If the sensor is near a device that causes pressure drop, such as a control valve, locating the sensor upstream from the device can decrease the risk of flashing. Alternatively, increasing back pressure downstream from the sensor can also reduce the risk of cavitation and flashing.

Cascading. Cascading of the fluid can occur when the flow rate diminishes to the point where the sensor tube is only partially filled.



Often, this occurs because fluid is flowing downward through a sensor installed in a vertical pipeline. (When a sensor is mounted this way, it is called the flag-mount orientation).

To help eliminate cascading, fluids should flow upward through a flagmounted sensor. Mounting the sensor in the preferred orientation often

reduces cascading. (See Orientation, page 13.) Increasing back

pressure downstream from the sensor can also reduce or eliminate cascading.

High points in the system. When measuring liquids, entrained air

(pockets of non-condensable gas) can collect in high points of a fluid system. If the fluid velocity is low, and/or the high points are very high relative to the system, entrained air pockets can grow and persist. If the air pocket releases and passes through the sensor, measurement error could occur. One possible solution is to install vent valves or air eliminators at a high point in the system, upstream from the sensor. Use your common plant practices if you choose to install vent valves or air eliminators.

Low points in the system. When measuring gases, liquid condensate can collect in low points of a fluid system. If the fluid velocity is low, and/or the low points are very low relative to the system, condensates can accumulate and persist. If the liquid passes through the sensor, measurement error could occur. One possible solution is to install condensate valves at a low point in the system, upstream from the sensor. Use your common plant practices if you choose to install condensate valves.

Checking for plugging or build-up

If the process fluid tends to build up in the piping, the sensor can become plugged or partially plugged due to build-up of material inside the sensor flow tubes. To determine whether plugging or build-up has occurred, check at the transmitter for a high drive gain and high density

reading (see page 50).

• If the drive gain and the density reading are both high, flush or clean the sensor, then check for an accurate density reading on water (or some other fluid with a known density). If the density is still wrong, plugging of the tube is probably not the problem.

• If either the drive gain or the density reading is not high, plugging of the tube is probably not the problem.

Purge Fittings

Keeping purge fittings sealed If the sensor has purge fittings, they should remain sealed at all times.

After a purge plug is removed, the sensor case should be purged with a

dry, inert gas (such as argon or nitrogen), and resealed. See Case

purging procedure, page 56.

Purging the case protects internal components. Before Micro Motion ships a sensor from the factory, it purges the sensor case. If you never loosen or remove the fittings, you do not have to be concerned about them.

Purge Fittings continued

Using purge fittings

Removing a purge plug

Case purging procedure

The primary reason for having purge fittings is to monitor pressure inside the sensor case. Some users, such as those measuring highly volatile fluids, install a pressure transmitter across the sensor purge fittings. A control device, connected to the pressure transmitter, shuts down the process if a change in pressure is detected. This provides additional protection should a rupture occur inside the sensor.

If you remove a purge plug from the sensor case, it is necessary to re-purge the case.

WARNING

Removing a purge plug will require the sensor case to be re-purged with a dry inert gas. Improper pressurization could result in serious personal injury.

Follow all instructions for re-purging the sensor case. See

Case purging procedure, below.

Read all instructions before performing the case purging procedure. It is not necessary to perform this procedure unless a purge plug has been removed.

1. Shut down the process, or set control devices for manual operation.

CAUTION

Performing the purge procedure while the flowmeter is operating could affect measurement accuracy, resulting in inaccurate flow signals.

Before performing the case purging procedure, shut down the process, or set control devices for manual operation.

2. Remove both purge plugs from the sensor case. If purge lines are being used, open the valve in the purge lines.

56 Micro Motion

Purge Fittings continued

3. Connect the supply of dry, inert gas to the inlet purge connection or open inlet purge line. Leave the outlet connection open.

• Exercise caution to avoid introducing dirt, moisture, rust, or other contaminants into the sensor case.

• If the purge gas is heavier than air (such as argon), locate the inlet lower than the outlet, so the purge gas will displace air from bottom to top.

• If the purge gas is lighter than air (such as nitrogen), locate the inlet higher than the outlet, so the purge gas will displace air from top to bottom.

4. Make sure there is a tight seal between the inlet connection and sensor case, so air cannot be drawn by suction into the case or purge line.

5. The purge time is the amount of time required for full exchange of atmosphere to inert gas. For each sensor size, the purge time is different. Refer to the table below. If purge lines are being used, increase the purge time to fill the additional volume of the purge line.

6. Avoid pressurizing the sensor case. At the appropriate time, shut off the gas supply, then immediately seal the purge outlet and inlet connections. If pressure inside the case elevates above atmospheric pressure during operation, the flowmeter density calibration will be inaccurate.

Rupture Disk

Using the rupture disk The primary reason for having a rupture disk is to vent process fluid from inside the sensor case, should the sensor flow tube rupture in a highpressure application. Some users, such as those measuring highpressure gases, install a pipeline at the rupture disk fitting, to help contain escaping process fluid. This provides additional protection should a rupture occur.

WARNING

Escaping high-pressure fluid can cause severe injury or death.

Stay clear of rupture disk pressure-relief area.

STEP 1.

Choosing a location

Choose a location for the sensor based on the requirements described in this section.

General guidelines

The following conditions must be met:

• Before operation, you must be able to stop flow through the sensor.

(During the zeroing procedure, flow must be stopped completely, and the sensor must be full of process fluid.)

• During operation, the sensor must remain full of process fluid.

• The sensor must be installed in an area that is compatible with the classification specified on the sensor approvals tag (see Figure 1 and

Figure 4).

Hazardous area installations

Make sure the hazardous areas specified on the approvals tags are suitable for the environment in which the sensor and booster amplifier will be installed. See Figures 1 and 4. For installation in an area that requires intrinsic safety, refer to Micro Motion UL, CSA, or ATEX documentation, shipped with the sensor or available from the Micro

Motion web site.

For a complete list of hazardous area classifications for Micro Motion sensors, refer to the EXPERT

Wiring from the remote booster amplifier to the sensor

The remote version of the booster amplifier requires connection of two cables from the booster amplifier to the junction boxes on the sensor:

• 9-wire cable (signal wires) — This cable is supplied by Micro Motion, and is pre-attached to the booster amplifier.

• 2-wire cable (drive wires) — In some locations, this cable may be supplied by Micro Motion. If the cable is not supplied, use twistedpair 18 AWG (0,75 mm 2 ) 2-wire cable.

To connect the 9-wire cable (signal wires):

1. Do not modify connections at the booster amplifier.

2. Do not place the 9-wire cable and 2-wire cable in the same cable tray.

3. At the sensor end of the 9-wire cable (see left side of Figure 10): a.

Clip all four drain wires and leave them disconnected.

b.

Clip the red and brown wires and insulate them.

c.

Matching by color, connect the remaining wires (except for the orange wire) to the corresponding terminals from the sensor feedthrough.

d. The orange wire in the cable does not have a corresponding orange wire from the sensor. Connect the orange wire to the terminal indicated in Figure 10. e.

Terminate the cable braid inside the cable gland.

11

To connect the 2-wire cable (drive wires):

1. Use twisted-pair 18 AWG (0,75 mm 2 ) 2-wire cable. Ensure that the cable is shielded, continuous from the booster amplifier to the sensor’s explosion-proof junction box. Two methods can be used:

• Metallic conduit

• Shielded or armored cable (do not place the 2-wire cable and 9wire cable in the same cable tray)

2. Connect the wires: a.

Connect terminal 1 at the sensor (see Figure 10) to terminal 1 at the booster amplifier (see Figure 11).

b.

Connect terminal 2 at the sensor to terminal 2 at the booster amplifier.

3. If the cable has a drain wire: a.

At the sensor end, clip the drain wire and leave it disconnected.

b.

At the booster amplifier end, connect the drain wire to the internal ground screw. See Figure 11.

4. If the cable has a braid, terminate it in the cable gland at both ends.

Wiring the sensor to the transmitter or direct host

WARNING

Failure to comply with requirements for intrinsic safety in a hazardous area could result in an explosion.

• For installation in an area that requires intrinsic safety, refer to Micro Motion UL, CSA, or ATEX documentation, shipped with the sensor or available from the Micro Motion web site.


13

CAUTION

Failure to seal sensor and transmitter housings could cause a short circuit, which would result in measurement error or flowmeter failure.



• If conduit is used, install drip legs in conduit.


CAUTION

Allowing the shield drain wires to contact the sensor junction box can cause flowmeter errors.

Do not allow the shield drain wires to contact the sensor junction box.

Junction box to 9-wire transmitter

If connecting from a D600 sensor with an integral booster amplifier and junction box (see Figure 1) or from a remote booster amplifier with a junction box (see the left side of Figure 4), follow the steps below to connect the 9-wire cable between the junction box and the transmitter.

1. Prepare and install the cable according to the instructions in Micro

Motion’s 9-Wire Flowmeter Cable Preparation and Installation

Guide.


3. Match the wires color for color. For wiring at the transmitter, see the transmitter Quick Reference Guide.


5. Ensure integrity of gaskets, grease all O-rings, then tightly close and seal the junction box cover and all housing covers on the transmitter.

14

Core processor to 4-wire transmitter or direct host

If connecting from a D600 sensor with an integral booster amplifier and core processor (see Figure 2) or from a remote booster amplifier with a core processor (see the right side of Figure 4), follow the steps below to connect the 4-wire cable between the core processor and the transmitter or direct host.

1. Use one of the following methods to shield the wiring:

• If you are installing unshielded wiring in continuous metallic conduit that provides 360° termination shielding for the enclosed wiring, go to Step 6.

• If you are installing a user-supplied cable gland with shielded cable or armored cable, terminate the shields in the cable gland.

Terminate both the armored braid and the shield drain wires in the cable gland. Go to Step 6.

• If you are installing a Micro Motion-supplied cable gland at the core processor housing:

Prepare the cable and apply shielded heat shrink as described below. The shielded heat shrink provides a shield termination suitable for use in the gland when using cable whose shield consists of foil and not a braid. Proceed to Step 2.

With armored cable, where the shield consists of braid, prepare the cable as described below, but do not apply heat shrink. Proceed to Step 2.

2. Remove the cover from the core processor.

3. Slide the gland nut and the clamping insert over the cable.

4. For connection at the core processor housing, prepare shielded cable as follows (for armored cable, omit steps d, e, f, and g): a.

Strip 4 1/2 inches (114 mm) of cable jacket.

b.

Remove the clear wrap that is inside the cable jacket, and remove the filler material between the wires.

c.

Remove the foil shield that is around the insulated wires, leaving

3/4 inch (19 mm) of foil or braid and drain wires exposed, and separate the wires.

d. Wrap the shield drain wire(s) around the exposed foil twice. Cut off the excess wire.

Shield drain wire(s) wrapped twice around exposed shield foil e.

Place the shielded heat shrink over the exposed shield drain wire(s). The tubing should completely cover the drain wires.

f.

Without burning the cable, apply heat (250 °F or 120 °C) to shrink the tubing.

16

Shielded heat shrink completely covers exposed drain wires g. Position gland clamping insert so the interior end is flush with the heat shrink.

h. Fold the cloth shield or braid and drain wires over the clamping insert and approximately 1/8 inch (3 mm) past the O-ring.

i.

Install the gland body into the core processor housing conduit opening.

5. Insert the wires through the gland body and assemble the gland by tightening the gland nut.

6. Identify the wires in the 4-wire cable. The 4-wire cable supplied by

Micro Motion consists of one pair of 18 AWG (0,75 mm 2 ) wires (red and black), which should be used for the VDC connection, and one pair of 22 AWG (0,35 mm 2 ) wire (green and white), which should be used for the RS-485 connection. Connect the four wires to the numbered slots on the core processor, matching corresponding numbered terminals on the transmitter. See Figure 12.

• Do not connect shield drain wires to this terminal

7. Reattach the core processor cover.

8. For wiring at the transmitter, see the transmitter Quick Reference

Guide.

9. If connecting to a direct host, you must connect the VDC wires from the core processor to a power supply, and you must connect the

RS-485 wires to the RS-485 terminals on the host.

• If you are connecting to an I.S. barrier supplied by Micro Motion

(MVD Direct Connect installations), the barrier supplies power to the core processor. a.

Connect all 4 wires of the 4-wire cable from the core processor to the barrier. Refer to the barrier documentation to identify the terminals at the barrier. b.

Ensure that there is no electromagnetic interference coupled onto the 4 wires between the core processor and the barrier.

18

• If you are not using a barrier: a.

Connect the VDC wires from the core processor (see

Figure 12) to an independent power supply. This power supply must connect only to the core processor. A recommended power supply is the SDN series of 24-VDC power supplies manufactured by Sola/Hevi-Duty.

b.

Do not ground either connection of the power supply. c.

Connect the RS-485 wires from the core processor (see

Figure 12) to the RS-485 terminals at the direct host. Refer to the vendor documentation to identify the terminals.

d. Ensure that there is no electromagnetic interference coupled onto the cables between the core processor and the power supply or direct host.

STEP 6.

Grounding the sensor

CAUTION

Improper grounding could cause measurement error.

To reduce the risk of measurement error:

• Ground the flowmeter to earth, or follow ground network requirements for the facility.


The sensor must be grounded. The sensor may be grounded via the piping if the joints in the pipeline are ground-bonded. If the sensor is not grounded via the piping, connect a ground wire to the sensor ground screw.

If using an integral booster amplifier, it is grounded with the sensor. If using a remote booster amplifier, it must be grounded separately, using the internal or external ground screw as required.

19

If national standards are not in effect, follow these guidelines to ground the sensor and remote booster amplifier via the provided ground screws:

• Use copper wire, 14 AWG (2,5 mm²) or larger wire size, for grounding.

• Keep ground leads as short as possible.

• Use less than 1 ohm impedance for ground leads.

• Connect ground leads directly to earth, or follow plant guidelines.

For instructions on grounding the transmitter, see the transmitter Quick

Reference Guide.
