Electronics Alerts; Processor Impaired Alerts - Fisher FIELDVUE DVC6200 Instruction Manual

Instruction Manual
D103409X012
Zero Power Condition as per figure 4‐6. It will remain latched in that condition until power to the instrument is cycled and the
failure alert has cleared. While in shutdown condition the instrument will remain powered up and able to communicate via HART.
Shutdown alerts are turned off by default.

Drive Current Shutdown
When enabled, the instrument shuts down whenever the drive current does not read as expected.
Drive Signal Alert—Drive Signal Alert checks the drive signal and calibrated travel. If one of the following conditions
exists for more than 20 seconds, the Drive Signal Alert is set.
For the case where Zero Power Condition is defined as closed:
Drive Signal < 10% and Calibrated Travel > 3%
Drive Signal > 90% and Calibrated Travel < 97%
For the case where Zero Power Condition is defined as open:
Drive Signal < 10% and Calibrated Travel < 97%
Drive Signal > 90% and Calibrated Travel > 3%
D Drive Signal Alert Enable—Yes or No. Drive Signal Alert Enable activates checking of the relationship between the
Drive Signal and the calibrated travel. Factory default is Yes.
D Drive Signal—Shows the value of the instrument drive signal in % (percent) of maximum drive.

Processor Impaired Alerts

D Offline/Failed Alert Enab—If enabled, set when the device is in a failed state and not controlling the input.
D Low Power Write Fail Enab—When enabled, an alert is generated if a write to the instrument is attempted and fails
when the loop current is less than 3.5 mA.
D Non‐Critical NVM Alrt Enab—When enabled, an alert is generated whenever there is a failure associated with
non‐critical NVM (non‐volatile memory).
D Critical NVM Shutdown—When enabled, the instrument shuts down whenever there is a failure associated with
critical NVM (non‐volatile memory).
D Flash ROM Shutdown—When enabled, the instrument shuts down whenever there is a failure associated with flash
ROM (read only memory).
D Reference Voltage Shutdown—When enabled, the instrument shuts down whenever there is a failure associated with
the internal voltage reference.
