Point Unhealthy Troubleshooting (continued)
Digital Input Internal Wetted Input exceeded range of
operation
Check field wiring. Measure incoming mA signal and verify that it is 10
mA.
Digital Input External Wetted Input exceeded range of
operation
Check field wiring. Measure voltage across digital inputs terminal points
and verify it is between -1 V and 21 V.
Digital Input NAMUR input exceeded range of operation Check field wiring. Verify mA signal through field device does not exceed
9 mA. Replace the field device.
Digital Input Digital Input mode configured as wrong type Verify field wiring and field device matches the configured Input Mode
found in the ToolboxST application.
Digital Input Open circuit detected on digital input signal Check the wiring between the terminal board and the device. Verify that
the recommended line monitoring resistors are being used.
Digital Input Short detected on digital input signal Check the wiring between the terminal board and the device. Verify that
the recommended line monitoring resistors are being used.
Pulse
Accumulator
Pulse input voltage exceeds the limits of the
YUAA hardware
Check field wiring. Measure incoming signal and verify that it is within -11
V and 21 V. Replace the field device.

Description Invalid calibration settings
Possible Cause
• Calibration file not detected
• Calibration file corrupted
• Calibration constants invalid
• Hardware Failure
Solution Replace the I/O pack.
97-98
Description Cold Junction temp [ ] exceeds range limit ([ ])
Possible Cause Cold junction input to the analog-to-digital converter exceeded the limits of the converter. If a cold
junctions fails, the CJ_Backup value is used.
Solution
• Check the mounting of the I/O pack on the terminal board.
• Replace the terminal board.
• Replace the I/O pack.
