Self Test Failures for Instrument Shutdown
Field Communicator Setup & Diag > Detailed Setup > Self Test Shutdown (1-2-8)
Upon shutdown, the instrument attempts to drive its output pressure to the zero current condition and no longer
executes its control function. In addition, the appropriate failure statuses are set. Once the problem that caused the
shutdown has been fixed, the instrument can be restarted by cycling the power or selecting Restart from the Mode
menu of the Field Communicator. Also see the Viewing Instrument Status section on page 61 for further details about
failures.
Follow the prompts on the Field Communicator display to determine the self test shutdown criteria from the
following:
D Done—Select this if you are done modifying the self test shutdown criteria.
D Flash ROM Fail—When enabled, the instrument shuts down whenever there is a failure associated with flash ROM
(read only memory).
D No Free Time—When enabled, the instrument shuts down whenever there is a failure associated with No Free Time.
D Temp Comp Fail—When enabled, the instrument shuts down whenever this is a failure associated with Temperature
Compensation.
D Ref Voltage Fail—When enabled, the instrument shuts down whenever there is a failure associated with the internal
voltage reference.
D Drive Current Fail—When enabled, the instrument shuts down whenever the drive current does not read as expected.
D NVM Fail—When enabled, the instrument shuts down whenever there is a failure associated with NVM (non-volatile
memory).
D Temp Sensor Fail—When enabled, the instrument shuts down whenever there is a failure associated with the internal
temperature sensor.
D Press Sensor Fail—When enabled, the instrument shuts down whenever there is a failure associated with the pressure
sensor.
D Travel Sensor Fail—When enabled, the instrument shuts down whenever there is a failure associated with the travel
sensor.
