Rosemount 8712
20 mA
Fix the analog loop current at 20 mA.
Simulate Alarm
Send the analog output into an alarm mA value. Actual mA value depends on
the alarm configuration.
• Rosemount Standard High Alarm – 22.6 mA
• Rosemount Standard Low Alarm – 3.75 mA
• Namur Compliant High Alarm – 22.6 mA
• Namur Compliant Low Alarm – 3.5 mA
Other
Fix the analog loop current to some other mA value between 3.5 mA and 23.0
mA.
End
This command cancels the analog loop test and returns the analog output
back into normal operating mode.
Pulse Output Loop Test
The Pulse Output Loop Test allows you to drive the frequency output at
terminals 3 and 4 to a desired value. The user then has the ability to compare
the pulse output value measured by auxiliary equipment to the desired pulse
output level set by the transmitter. On the LOI the test will end after five
minutes if the transmitter is not returned to normal operation manually.
Select Value
Set the value of the pulse output for the test to a value between 1 pulse/day to
10,000 Hz.
End
This command cancels the pulse output loop test and returns the pulse output
back into normal operating mode.
Tune Empty Pipe
Empty Pipe allows you to view the current value and configure the diagnostic
parameters. For more detail on this parameter see Appendix C: "Diagnostics".
Empty Pipe Value
Read the current Empty Pipe Value. This number is a unitless number and is
calculated based on multiple installation and process variables. For more
detail on this parameter see Appendix C: "Diagnostics".
