1.1 Micro Motion 9739 MVD transmitter
electronics module upgrade

The Micro Motion 9739 MVD transmitter electronics module upgrade is the replacement
for the RFT9739 electronics module and power board in your existing 9739 transmitter
with the 9739 MVD electronics module. The base housing, conduit connections, and
distance capabilities that currently exist for your RFT9739 transmitter apply to the
9739 MVD technology.

Planning

The 9739 MVD transmitter retrofit kit contains the following:

• 9739 MVD electronics module (with or without display)

• Ferrite clip

• Heat sink

• O-ring

• Terminal block kit (for optional replacement of existing terminal block connectors)

• Transmitter housing cover (for units installed with a display only)

Important

If you are replacing and installing an electronics module without a display, you can reattach
the existing transmitter housing cover. A new housing cover is not included as part of the
retrofit kit for units without a display.

Before upgrading your RFT9739 transmitter

CAUTION!

When upgrading your RFT9739 transmitter to use the 9739 MVD electronics module, you must
install a unit with the same type of display that your RFT9739 module used. For example, if
your RFT9739 electronics module has no display, you must upgrade to a 9739 MVD electronics
module that has no display. Failure to install modules with similar interfaces will invalidate all
approvals for the 9739 transmitter installation.

The 9739 MVD technology upgrade does not support the following RFT9739 transmitter
features:

Installation Guide 1

Planning

• Viscosity measurement

2.1 Back up and record the RFT9739 configuration
settings

Before removing the RFT9739 electronics module from the transmitter, you should record
the current configuration settings of this module. For the purpose of the 9739 MVD
electronics module upgrade, you have the following options:

• To download configuration settings to a PC, you can use the Micro Motion ProLink II

software (v2.91v2.91 or later). The ProLink II software provides a feature that allows
you to save configuration sets to your PC to upload to another device. Depending on
your digital communications, you will need one of the following signal converters
(and adapters, if necessary):

- RS-232 to Bell 202 signal converter

- RS-232 to RS-485 signal converter

- USB to Bell 202 signal converter

- USB to RS-485 signal converter

- Adapters as required (e.g. 9-pin to 25-pin)

Important

ProLink II will not download the settings for the security mode or fault output from the
RFT9739 transmitter. To save these settings, you must record the S1 switch positions of
switches 1 through 3 (which set the security mode), and switch 9 (which sets the fault output).
All other switch configuration settings are auto-detected and downloaded via the Micro
Motion ProLink II software.

Important

You cannot use the AMS Device Manager software or Field Communicator to back up the
RFT9739 transmitter configuration settings. The 9739 MVD transmitter has a different HART

Installation Guide 21

Installing the 9739 MVD electronics module

2.4 Upload the transmitter configuration using ProLink II

Prerequisites

• You should have downloaded the transmitter configuration from your RFT9739

electronics module to your PC, and have this file available to access via ProLink II.

Tip

If you manually recorded the RFT9739 transmitter configuration, refer to the Micro Motion
9739 MVD Transmitters: Configuration and Use Manual for information on configuring the

9739 MVD transmitter.

• Depending on your digital communications, you need the appropriate signal

converter to connect to the 9739 MVD transmitter via ProLink II. You will need one
of the following signal converters (and adapters, if necessary):

- RS-232 to Bell 202 signal converter

- RS-232 to RS-485 signal converter

- USB to Bell 202 signal converter

- USB to RS-485 signal converter

- Adapters as required (e.g. 9-pin to 25-pin)

Procedure

1. Restore power to the 9739 MVD transmitter.

CAUTION!

If the transmitter is in a hazardous area, do not apply power to the unit with the housing
cover removed. Applying power to the unit with the housing cover removed could cause
an explosion. To upload configuration information in a hazardous environment, use a
communication method that does not require applying power to unit with the
transmitter housing cover removed.

The flowmeter will automatically perform diagnostic routines. For transmitters with
a display, the status LED will turn green and begin to flash when the startup
diagnostics are complete. If the status LED exhibits different behavior, an alarm
condition is present.

2. Allow the electronics to warm up for approximately 10 minutes before relying on

process measurements. Although the sensor is ready to receive process fluid shortly
after power-up, the electronics can take up to 10 minutes to warm up completely.
For HART/Bell 202 communications, connect to the HART + and – clips. These clips
are polarity insensitive.

3. Depending on your digital communications used, connect your signal converter

leads to the following locations on the 9739 MVD electronics module user interface
(see Figure 2-17):

22 Micro Motion® 9739 MVD Electronics Module Upgrade

AA B

Installing the 9739 MVD electronics module

• For Modbus/RS-485 communications, connect to Service Port A and B clips.

Typically, the black lead connects to clip A, and the red lead connects to clip B.

Important

The SP (Service Port) clips on the user interface of the 9739 MVD transmitter are directly
connected to the RS-485 terminals 26 and 27 of the transmitter. If you have wired the
transmitter for RS-485 digital communications, you must directly connect to the
transmitter using the RS-485 terminal block connections or disconnect the RS-485
terminal connections to use the Service Port connections.

5. In ProLink II, choose File > Save to Xmtr from File, and navigate to the configuration file
that you downloaded.

See the ProLink II manual at www.micromotion.com for more information on this
feature.

Postrequisites

If this is the initial startup, or if power is been off long enough to allow components to
reach ambient temperature, allow the electronics to warm up for approximately 10
minutes before relying on process measurements. Although the sensor is ready to receive
process fluid shortly after power-up, the electronics can take up to 10 minutes to reach
thermal equilibrium. During this warm-up period, you may observe minor measurement
instability or inaccuracy.

3.2

3.2.1

• Perform a loop test on the 9739 MVD transmitter.

• If indicated by the loop test results, trim the mA output.

• Zero the flowmeter.

For additional information on configuring the 9739 MVD transmitter, see Micro Motion
9739 MVD Transmitters: Configuration and Use Manual.

Perform a loop test

A loop test is a way to verify that the transmitter and the remote device are
communicating properly. A loop test also helps you know whether you need to trim mA
outputs.

Tip

Loop tests are not required. However, Micro Motion recommends performing a loop test for every
input or output available on your transmitter.

Perform a loop test using the display

• Test the mA output(s).

1. Choose OFFLINE MAINT > SIM > AO1 SIM, and select SET 4 MA or another mA
output value.

Dots traverse the display while the output is fixed.

Installation Guide 27

9739 MVD transmitter startup

• Test the frequency output(s).

2. Read the mA current at the receiving device and compare it to the transmitter
output.

The readings do not need to match exactly. If the values are slightly different,
you can correct the discrepancy by trimming the output.

3. At the transmitter, activate Select.

4. Scroll to and select SET 20 MA.

Dots traverse the display while the output is fixed.

5. Read the mA current at the receiving device and compare it to the transmitter
output.

The readings do not need to match exactly. If the values are slightly different,
you can correct the discrepancy by trimming the output.

6. At the transmitter, activate Select.

1. Choose OFFLINE MAINT > SIM > FO SIM, and select the frequency output value.

The frequency output can be set to 1, 10, or 15 kHz.

Trim mA outputs

Trimming the mA output establishes a common measurement range between the
transmitter and the device that receives the mA output.

Restriction

You cannot trim mA outputs with the display. You must use ProLink II or the Field Communicator to
trim the mA outputs.

Trimming the mA output is not required. However, if there is a small discrepancy in the mA
reading between the transmitter and the receiving device, trimming the output will
correct this.

Installation Guide 31

9739 MVD transmitter startup

Note

Any trimming performed on the mA output should not exceed ±200 microamps. If more trimming is
required, contact Micro Motion customer service.

3.3.1 Trim the mA outputs using ProLink II

1. Choose ProLink > Calibration > Milliamp 1 Trim or ProLink > Calibration > Milliamp 2 Trim.

2. Follow the instructions in the guided method.

3.3.2 Trim mA outputs using the Field Communicator

1. Press Service Tools > Maintenance > Routine Maintenance > Trim mA output 1 to start the mA
trim procedure.

2. Follow the instructions in the guided method to trim the mA output.

3. Choose Service Tools > Maintenance > Routine Maintenance > Trim mA output 2 to start the
trim procedure for the secondary mA output.

4. Follow the instructions in the guided method to trim the mA output.

3.4 Zero the flowmeter

Zeroing the flowmeter establishes a baseline for process measurement by analyzing the
sensor's output when there is no flow through the sensor tubes.

Prerequisites

To prepare for the zero procedure:

1. Record the current zero value.

2. Allow the flowmeter to warm up for at least 20 minutes after applying power.

3. Run the process fluid through the sensor until the sensor temperature reaches the
normal process operating temperature.

4. Stop flow through the sensor by shutting a valve downstream from the sensor.

5. Ensure that flow has completely stopped through the sensor, and that the sensor is
completely full of process fluid.

6. Check the flow rate reported by the transmitter. If the flow rate is close to 0, you
should not need to zero the flowmeter.

Note

Do not zero the flowmeter if a high-severity alarm is active. Correct the problem, then zero the
flowmeter. You may zero the flowmeter if a low-severity alarm is active.

32 Micro Motion® 9739 MVD Electronics Module Upgrade

3.4.1 Zero the flowmeter using the display

1. Initiate flowmeter zero by choosing OFFLINE MAINT > ZERO > CAL ZERO, and select
CAL/YES?.

Dots traverse the display while flowmeter zero is in progress.

2. Read the zero result on the display.

The display will report CAL PASS if the zero was successful, or CAL FAIL if it was not. If
the zero fails, restore the factory zero (if available).

Tip

Flowmeters with an enhanced core processor are capable of restoring the factory zero as a
way to recover from a failed field zero.

9739 MVD transmitter startup

3.4.2

Zero the flowmeter using ProLink II

1. Choose ProLink > Calibration > Zero Calibration.

2. Modify Zero Time, if desired.

Zero Time controls the amount of time the transmitter takes to determine its zero­flow reference point.

• A long zero time may produce a more accurate zero reference, but is more likely

to result in a zero failure. This is due to the increased possibility of noisy flow,
which causes incorrect calibration.

• A short zero time is less likely to result in a zero failure but may produce a less

accurate zero reference.

The default Zero Time is 20 seconds. For most applications, the default Zero Time is
appropriate.

3. Click Perform Auto Zero.

The Calibration in Progress light will turn red during the zero procedure. At the end of
the procedure:

• The Calibration in Progress light will return to green if the zero was successful.

• The Calibration Failure light will turn red if the zero procedure failed.

3.4.3

Installation Guide 33

Zero the flowmeter using the Field Communicator

To initiate the flowmeter zero, press Service Tools > Maintenance > Zero Calibration > Perform
Auto Zero.

The display will report Calibration in progress. When the calibration is complete, the display
reports Auto zero complete if the zero was successful, or Auto zero failed if it was not.
