Controller recovered from internal temperature fault
Allen-Bradley · Logix 5000
What does 17-37 mean?
This fault indicates that the controller has successfully recovered from an automatic shutdown caused by exceeding its internal temperature threshold. The module's temperature has decreased to a suitable level, re-enabling controller voltages.
Common Causes
- Controller recovered from automatic shutdown due to high internal temperature
- Module's temperature decreased to a suitable level after exceeding temperature threshold of preservation fault
Repair Steps & Checklist
Click steps to track your progress.
- 1
Inspect the electrical cabinet's ventilation openings, filters, and cooling fans for obstructions or proper operation.
- 2
Measure the internal ambient temperature within the electrical cabinet and compare it against the Allen-Bradley Logix 5000 operating temperature specifications.
- 3
Verify proper spacing and airflow around the Logix 5000 controller modules as per the installation manual guidelines.
- 4
Measure the input voltage to the Logix 5000 power supply module and verify it is within the specified operating range.
- 5
Inspect the Logix 5000 controller modules and rack for excessive dust accumulation that could hinder heat dissipation.
