Interrogation with the
ProLink
®
program
The transmitter provides diagnostic messages, which can be viewed
using a special version of the ProLink program. (The HART
Communicator cannot be used for troubleshooting.) Contact the Micro
Motion Customer Service Department for the special ProLink software
version:
• In the U.S.A., phone 1-800-522-6277
• Outside the U.S.A., phone 303-530-8400
• In Europe, phone +31 (0) 318 549 443
• In Asia, phone 65-770-8155
Figure 4-2 (next page) explains how to connect the ProLink PC Interface
adaptor to the RFT9709.
Fault detection indicates an interruption in the functional integrity of the
sensor and the electronics, including the sensor pickoff coils, drive coil,
and RTD. Faults, such as a short or an open circuit, are detected by the
ProLink program.
The RFT9709 runs continuous self-diagnostic tests. If these tests reveal
a failure, the ProLink program displays an error message. Self-testing
allows the RFT9709 to check its own circuitry.
Output test and trim
The RFT9709 works with a Micro Motion flow sensor to provide flow
information. Therefore, many of the troubleshooting checks pertain only
to the sensor. However, the ProLink program enables the user to
perform other tests:
• Performing an mA output test forces the transmitter to produce a user-
specified current output of 2 to 22 mA.
• Performing a frequency/pulse output test forces the transmitter
to produce a user-specified frequency output between 0.1 and
15,000 Hz.
• Performing an mA output trim allows adjustment of the primary and
secondary mA outputs against a highly accurate external standard
such as a digital multimeter (DMM) or receiving device.
If the transmitter is in security mode 8, mA output test, mA output trim,
and frequency/pulse output test cannot be performed.
• Perform mA trim and/or test procedures, if necessary, with the ProLink
program.
• For more information, see
