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.
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 Table 6-2, page 64.)
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, see Section 6.3, page 64.
• To perform a master reset, see Section 7.7, page 79.
Milliamp output trim, milliamp output test, and frequency/pulse output
test procedures 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 any of the following manuals or
in AMS on-line help:
•
Using the HART Communicator with Micro Motion Transmitters
• Using ProLink Software with Micro Motion Transmitters
• Using Modbus Protocol with Micro Motion Transmitters
To enter security mode 8:
1. Note the position of switch 5.
2. Set switches 1, 2, 3, and 10 to the ON position.
3. Set switches 4, 5, and 6 to the OFF position.
4. Locate the Reset button on the transmitter front panel.
5. Press and hold the Reset button for ten seconds.
6. Reset switch 5 to the desired position (as noted in Step 1).
7. Reset switch 10 to the OFF (OPERATE) position.
8. 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.
9. Leave switches 1, 2 and 3 in the ON position to maintain security
mode 8.
