99-130
Description IOPoint [ ] - Current output commanded current feedback error
Possible Cause
•
The measured current feedback does not match the commanded current.
•
There is an open circuit on an output.
•
Output impedance is too high (max allowed 800 Ohms).
Solution
•
Check the field wiring and device.
•
Verify that the commanded output is within output range.
•
Replace the I/O pack.
131-162
Description IOPoint [ ] - Open field wire detected
Possible Cause An open circuit has been detected at the terminal board based on the sensor type.
Solution
•
Digital Input:
−
Check the wiring between the terminal board and the device.
−
Verify that the recommended line monitoring resistors are being used (refer to the I/O pack user documentation).
•
Thermocouple Input: verify the wiring of the thermocouple at the inputs.
163-194
Description IOPoint [ ] - Thermocouple input millivolt exceeds hardware limit ([ ] mV)
Possible Cause
•
Thermocouple millivolt input exceeds the hardware limit
•
An open thermocouple was detected.
Solution This is usually not a I/O pack or terminal board failure if other thermocouples are working correctly.
•
Check the field wiring, including shields.
•
Check the installation of the I/O pack on the terminal board.
•
Replace the I/O pack.
