1. 1

   Verify the nominal 24VDC input supply voltage at the NX-series CPU power terminals for stability and correct levels.

2. 2

   Inspect all power supply wiring, fuses, and terminal connections leading to the NX-series CPU for looseness, damage, or corrosion.

3. 3

   Check the integrity of the main plant power supply, including circuit breakers and distribution, for stability and absence of transient events affecting the CPU's power source.

4. 4

   Review the NX-series CPU's diagnostic log for any concurrent or preceding power supply alarms, undervoltage warnings, or related system events.
