DVC6200 Digital Valve Controller
Configure / Setup, Detailed Setup, and Alerts. Follow
the prompts on the Field Communicator display to
configure the following Alerts: Electronic Alerts,
Sensor Alerts, Environmental Alerts, Travel Alerts,
Travel History Alerts, SIS Alerts (instrument level
ODV), and Alert Record.
Note
The Alerts section covers alerts and
shutdowns. An alert, if enabled, can
provide information on operation and
4
performance issues. A shutdown, if
enabled, and upon the occurrence of
the associated failure alert, will cause
the instrument air output to go to the
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.
D Electronic Alerts (1-2-3-1)
D Drive Current Shutdown— When enabled, the
instrument shuts down whenever the drive current
does not read as expected.
Drive Signal Alert (1-2-3-1-2)
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.
42
D Drive Signal—Shows the value of the
instrument drive signal in % (percent) of maximum
drive.
Processor Impaired Alerts (1-2-3-1-3)
D Offline/Failed Alrt Enab—If enabled, set when
the device is in a failed state and not controlling the
input.
D Low Power Write Alert Enabled—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.
D Sensor Alerts (1-2-3-2)
D Tvl Sensor Shutdown
When enabled, the instrument shuts down
whenever there is a failure associated with the
travel sensor.
D Temp Sensor Shutdown
When enabled, the instrument shuts down
whenever there is a failure associated with the
temperature sensor.
D Press Sensor Shutdown
When enabled, the instrument shuts down
whenever there is a failure associated with the
pressure sensor.
