Micro Motion Rack-Mount Transmitter for Commercial Trade - Model RFT9739 Owner's Manual

Configuring the RFT9739
Rack-Mount Transmitter for
Commercial Trade
Introduction These instructions explain how to configure a Version 3 rack-mount
RFT9739 transmitter for use in custody transfer and other commercial
trade applications.
For commercial trade applications, the transmitter has security
switches and an optional lockout Kit.
* Security switches enable the user to write-protect all configuration
and calibration parameters and/or disable flowmeter zeroing and
resetting of totalizers.
The lockout kit prevents access to the transmitter’s electronics.
NOTE
Before securing the transmitter configuration or
installing the lockout screws, make sure the transmitter
has been properly installed in the rack and the
flowmeter has been zeroed, according to the
appropriate sections in the instruction manual that is
shipped with the transmitter.
Securing the transmitter . A Version 3 rack-mount RFT9739 has three security switches.
configuration » Switches are on the processor board. Remove the bottom cover of
the housing to access the switches. Top and bottom covers are
secured to the housing by screws.
* Figure 1 illustrates the switches, which are labeled SECURE 1,
SECURE 2, and SECURE 3.

Security modes Switches 1, 2, and 3 enable the user to disable flowmeter zeroing,
disable resetting of totalizers, and write-protect all configuration and
calibration parameters.
Switch settings enable any of eight possible security modes. Different
modes determine which functions are disabled and whether
configuration and calibration parameters are write-protected. The
following functions can be disabled: |
Flowmeter zeroing through digital communications
Flowmeter zeroing with the Scroll and Reset buttons
Totalizer reset, with flow, using digital communications
Totalizer reset, with flow, using the Scroll and Reset buttons
Totalizer reset, with zero flow, using digital communications
Totalizer reset, with zero flow, using the Scroll and Reset buttons
Table 1 lists the parameters that are write-protected and functions that
are disabled for each security mode. Security modes 1 through 7 are
entered immediately when switches are set.
For information about security mode 8, see page 3.

Configuration and
calibration parameters
*Security mode 8 is not entered when switches are set. For more information about security mode 8, see page 3.
Security mode 8 When transmitter security is set for mode 8, the transmitter meets
security requirements for custody transfer described in National
Institute of Standards and Technology (NIST) Handbook 44.
NOTE
Once the transmitter is configured for security mode 8,
the security mode cannot be changed unless a master
reset is performed.
A master reset causes all configuration parameters to
return to their default values, and requires complete
characterization and reconfiguration of the
transmitter.
If the user attempts to enter a new security mode or change the
transmitter configuration after entering security mode 8:
* Internal totalizers stop counting
The frequency/pulse output goes to 0 Hz
mA outputs go to 4 mA
The display reads "SECURITY BREACH; SENSOR OK"
Custody transfer event registers record each change made to
defined configuration and calibration parameters. (For a list of these
parameters, see the instruction manual that is shipped with the
transmitter.)
The security breach continues, and totalizers and outputs remain
inactive, until the transmitter is reconfigured for security mode 8, or
until a master reset has been performed. Custody transfer event
registers are not affected by a master reset. For information about
event registers, or to perform a master reset, see the instruction
manual that is shipped with the transmitter.
NOTE
Milliamp output trim, milliamp output test, and
frequency/pulse output test cannot be performed after
security mode 8 is entered.
Before entering security mode 8, perform milliamp
trim and/or test procedures, if necessary, as described
in either of the following manuals:
* Using the HART Communicator with Micro Motion
Transmitters
* Using ProLink Software with Micro Motion

Lockout screw installation
procedure
To enter security mode 8:
Note the position of switch 5.
Set switches 1, 2, 3, and 10 to the ON position.
Set switches 4, 5, and 6 to the OFF position.
Locate the ZERO button on the transmitter front panel.
Press and hold the ZERO button for five seconds.
Reset switch 5 to the desired position (as noted in Step 1).
Reset switch 10 to the OFF (OPERATE) position.
To verify the transmitter is in security mode 8, use the Scroll button
to scroll through the display screens. The transmitter is in security
. mode 8 if the CONFIG REG and CALIBRATE REG screens
appear.
00 М Ол В о № +
To verify the transmitter is in security mode 8:
Use the Scroll button to scroll through process variable screens to
event register screens. If event register screens appear, the transmitter
is in security mode 8.
To make changes to configuration or calibration parameters once
security mode 8 is entered:
1. Set switches 1, 2, and 3 to the OFF position.
2. Make changes through digital communication or with the Scroll and
Reset buttons. Custody transfer event registers record each change
made to defined configuration and calibration parameters. For more
information about digital communications, see the following
instruction manuals: |
e Using the HART Communicator with Micro Motion Transmitters
* Using Modbus Protocol with Micro Motion ELITE RFT9739
Transmitters
* Using ProLink Software with Micro Motion Transmitters
3. Reset switches 1, 2, and 3 to the ON position.
To re-enter security mode 8:
If security mode 8 has been established previously, and the security
mode has been temporarily changed, it is not necessary to use the
Reset button to re-enter security mode 8. In such a case, resetting
switches 1, 2, and 3 to the ON position will re-enter security mode 8
immediately.
If a master reset has been performed, it is necessary to use the ZERO
button method to re-enter security mode 8. See the procedure at the
top of this page.
NOTE
For custody transfer and other commercial trade
applications in the United States and Europe, both
mounting screws are required (see Figure 2).
Figure 2.
Lockout screw
Note for Figure 2.
The lockout kit includes two screws.
To install the lockout screws, refer to Figure 3 and follow these steps:
1. The front panel of the transmitter is held in place by four screws.
Replace the two top or two bottom screws with the lockout screws.
2. Make sure all four front-panel screws are tightly secured to the rack
assembly.
3. A weights and measures inspector will inspect the installation.
4. To complete the installation, the inspector runs a wire seal through
the holes in the lockout screws, then secures the seal.
