or Miscellaneous Alerts. Starting from a cleared
database, the first 20 alerts that become active will be
stored in memory.
Select Setup & Diag, Detailed Setup, Alerts, and Alert
Record. Follow the prompts on the Field
Communicator display to Display Record, Clear
Record, set the Inst Date & Time (Instrument Date
and Time), and enable Record Groups.
Display Record—Displays all recorded alerts
and the date and time the alerts were recorded.
Clear Record—Clears the alert record. To clear
the alert record, all alerts in enabled groups must be
inactive.
Inst Date & Time—Permits setting the
instrument clock. When alerts are stored in the alert
record, the date and time (obtained from the
instrument clock) that they were stored is also stored
in the record. The instrument clock uses a 24-hour
format. Enter the date and time in the form:
MM/DD/YYYY HH:MM:SS, where MM is two digits for
the month (1 through 12), DD is two digits for the day
(1 through 31), and YYYY is four digits for the year
(1980 through 2040), HH is two digits for the hour (00
to 23), MM is two digits for the minutes (00 to 59), and
SS is two digits for the seconds (00 through 59).
Record Group Enab—Permits enabling one or
more alert groups. Table 5-2 lists the alerts included in
each of the groups. When any alert from an enabled
group becomes active, active alerts in all enabled
groups are stored.
Self Test Failures for Instrument
Shutdown
Select Setup & Diag, Detailed Setup, and Self Test
Shutdown. Follow the prompts on the Field
Communicator display to determine the self test
shutdown criteria from the following selections: Done,
Flash ROM Fail (Flash Read Only Memory Failure),
No Free Time, Ref Voltage Fail (Reference Voltage
Failure), Drive Current Fail, Critical NVM Fail (Critical
Non-Volatile Memory Failure), Temp Sensor Fail
(Temperature Sensor Failure), Press Sensor Fail
(Pressure Sensor Failure), or Tvl Sensor Fail (Travel
Sensor Failure). 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 5-3 for
further details about failures.
Done—Select this if you are done modifying the
self test shutdown criteria.
Flash ROM Fail—When enabled, the instrument
shuts down whenever there is a failure associated with
flash ROM (read only memory).
No Free Time—When enabled, the instrument
shuts down whenever there is a failure associated with
No Free Time.
Temp Comp Fail—When enabled, the instrument
shuts down whenever this is a failure associated with
Temperature Compensation.
Ref Voltage Fail—When enabled, the instrument
shuts down whenever there is a failure associated with
the internal voltage reference.
Drive Current Fail—When enabled, the
instrument shuts down whenever the drive current
does not read as expected.
Critical NVM Fail—When enabled, the instrument
shuts down whenever there is a failure associated with
critical NVM (non-volatile memory).
Temp Sensor Fail—When enabled, the
instrument shuts down whenever there is a failure
associated with the internal temperature sensor.
Press Sensor Fail—When enabled, the
instrument shuts down whenever there is a failure
associated with the pressure sensor.
Tvl Sensor Fail—When enabled, the instrument
shuts down whenever there is a failure associated with
the travel sensor.
Transmitters/Switches
These menu items are only available on units that
have the optional position transmitter / limit switch
hardware installed. Select Setup & Diag, Detailed
Setup, and Transmitter/Switches. Follow the prompts
on the Field Communicator display to configure the
following: Switch 1 Trip Point, Switch 1 Closed, Switch
2 Trip Point, Switch 2 Closed, and Transmitter Action.
