Internal Module Fault / Over Temperature
Allen-Bradley · Compact 5000 I/O Analog Modules
What does Steady red mean?
An issue internal to the module has occurred, such as a nonrecoverable fault, a calibration fault, or an over-temperature condition. This indicates a critical problem within the module hardware or firmware, affecting its operation and potentially requiring module replacement or environmental correction.
Common Causes
- Nonrecoverable internal module fault detected.
- A calibration fault occurred on the channel.
- Module operating above its specified ambient temperature range.
- Incorrect current levels applied to the module, potentially causing overheating.
Repair Steps & Checklist
Click steps to track your progress.
- 1
If the indicator is steady red following initial power-up and remains, replace the module.
- 2
If a calibration fault occurred, cycle power to the module to return the channel to its factory calibration setting.
- 3
Check the ambient temperature at the module installation location and lower it if it exceeds specifications.
- 4
Verify the applied current levels to the module meet specifications (refer to publication 5069-TD001).
