Click steps to track your progress.

1. 1

   Inspect all power supply input terminals, main circuit connections, and grounding connections on the Omron NJ/NX controller for secure attachment, corrosion, or damage.

2. 2

   Verify the Omron NJ/NX controller's diagnostic logs and system alarms for additional error codes, warnings, or detailed status messages related to the temperature monitoring circuit.

3. 3

   Check the controller's system parameters and configuration settings related to internal temperature monitoring or associated safety functions to ensure they are correctly configured and within specified operational limits.

4. 4

   Measure the input supply voltage and frequency at the controller's main power input terminals to confirm they are within the specified operational range for the Omron NJ/NX controller.
