Controller recovered from internal temperature fault

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.

• 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

Click steps to track your progress.

1. 1

   Inspect the electrical cabinet's ventilation openings, filters, and cooling fans for obstructions or proper operation.

2. 2

   Measure the internal ambient temperature within the electrical cabinet and compare it against the Allen-Bradley Logix 5000 operating temperature specifications.

3. 3

   Verify proper spacing and airflow around the Logix 5000 controller modules as per the installation manual guidelines.

4. 4

   Measure the input voltage to the Logix 5000 power supply module and verify it is within the specified operating range.

5. 5

   Inspect the Logix 5000 controller modules and rack for excessive dust accumulation that could hinder heat dissipation.
