To verify the transmitter is in security mode 8:
1. Configure the security mode, as described above.
2. Wait until the diagnostic LED blinks ON once per second.
3. Move switch 1, 2, or 3 to the OFF position.
4. If the diagnostic LED blinks ON 4 times per second, the RFT9709 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 using the switches (see
Communication settings ,
page 47) or with a special version of the ProLink program. The HART
Communicator cannot be used. (Contact the factory for additional
ProLink information.) Event registers record changes made to defined
configuration and calibration parameters (see Section 3.3, page 29).
3. Set switches 1, 2, and 3 to the ON position.
To reenter 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 zero
button to reenter security mode 8. In such a case, resetting switches 1,
2, and 3 to the ON position will reenter security mode 8 immediately.
If a master reset has been performed (see Section 4.6, page 37), it is
necessary to use the zero button method to reenter security mode 8.
See the procedure on the previous page.
To change from security mode 8 to another security mode:
1. Perform a master reset (see Section 4.6, page 37).
2. Perform characterization and reconfiguration procedures using a
special version of the ProLink program. The HART Communicator
cannot be used. (Contact the factory for additional ProLink
information.)
3. Set switches 1, 2, and 3 to the desired positions, See Table C-2,
page 49.
