YUAA Diagnostic Alarms
The following diagnostic alarms are specific to the YUAA universal analog functions. Common Mark VIeS I/O module
processor diagnostics are listed separately.
32-63
Description
Failed loading configuration for point [ ]
Possible Cause
•
Attempted to change an already configured point to a different point type without making the point unused first.
•
Hardware communication failure
Solution
•
Set the PointType for the specified point to Unused and download before changing to desired PointType.
•
Re-download configuration
64-95
Description
Point [ ] unhealthy
Possible Cause
Use the following table to identify the possible cause for this unhealthy point, based on the configured
Mode of the channel and field device.
Solution
Use the following table to identify a solution for this unhealthy point, based on the configured Mode of the
channel and field device.
Point Unhealthy Troubleshooting
Mode
Possible Cause
Solution
CurrentInput
The excitation to transducer is wrong or
missing.
Check the field wiring and connections to indicated analog input channel.
Check the field device for failure. Check the YUAA power from terminal
board screw.
CurrentInput
The transducer is defective.
Replace the transducer.
CurrentInput
There is an open or short-circuit on input.
Check the field wiring and connections to indicated analog input channel.
CurrentInput
The analog current input is beyond the
specified range 4-20 mA
Check the field wiring and connections to indicated analog input channel.
Check the field device for failure. If incorrectly configured, from the
ToobloxST Component Editor, modify the specified range.
Current Input
The burden resistor protection has been
activated, greater than 30 mA has been
detected
Check the field wiring and connections to indicated analog input channel.
Current Input
Hardware failure in the I/O Module or Terminal
Board.
Replace the I/O Module.
Replace the Terminal Board.
VoltageInput
The excitation to transducer is wrong or
missing.
Check the field wiring and connections to indicated analog input channel.
Check the field device for failure. Check the YUAA power from terminal
board screw is correct.
VoltageInput
The transducer is defective.
Replace the transducer.
VoltageInput
There is an open or short-circuit on input.
Check the field wiring and connections to indicated analog input channel.
VoltageInput
The analog voltage input is beyond the
specified range.
Check the field wiring and connections to indicated analog input channel.
Check the field device for failure. If incorrectly configured, from the
ToolboxST Component Editor, modify the specified range.
