System Configuration Menu
The
System Config
menu displays the following options
Input Quality Alarms and Range
Alarms*.
Input Quality Alarms
–
Directs you to a sub-menu. When accessed, this will allow you turn
On or Off the following menu options
Allow Measurement out of Conformance Range,
Allow Limited,
and
Allow Dropping.
These settings allow the user to determine how
certain types of input quality issues are handled and how they can affect the Device
Variables, Dynamic Variables and AO. See Section 6 for more information.
Range Alarms
–
Directs you to a sub-menu. When accessed, you will able to configure Range
Alarms 1-4. You can also select and reset an actively latched range alarm provided that
the input has returned to a non-alarm level. See Section 1 more information on Range
Alarms.
Each alarm has the following settings:
Enabled:
[Disabled] Enables or Disables the Range Alarm
Source:
[Primary Variable] The Variable to be used as a source for the Range Alarm
Response:
[Warning] How to react if the specified condition occurs:
Warning
- Sends a warning message to the HART Handheld/FDT host, TDZ
3
display and
sets a HART status bit.
Alarm
- Sends the AO into fail mode and sends an alarm message to the HART
Handheld/FDT host, TDZ
3
display. It also sets a (different) HART status bit.
Assertion:
[In Range] Indicates if the Range Alarm should detect if the source variable goes
Out of range, or goes In range.
Low:
[0.00] The defined lower limit of the Range Alarm
High:
[100.00] The defined upper limit of the Range Alarm
Latching:
[Enabled] Disables or Enables latching of the alarm. Non-latching alarms return to a
non-alarm state whenever the process input returns to a non-alarm level. Once tripped, a
latching alarm remains in an alarm state until the input returns to a non-alarm level and is
reset. Latching alarms can be reset from the Range Alarm or Custom Calibration menu.
Note:
The
Range Alarms
menu is only visible if
Advance Settings
is Enabled.
Note:
If a Range Alarm Response is set to Alarm, the AO will always perform a fail response
even if the Source Device Variable is not assigned to the PV.
Note:
After making all desired changes enter
SEND
to update the unit.
