24V supply low

What does 47 mean?

The 24V DC supply generated by the switch-mode power supply (SMPS) on the power card is operating below its acceptable voltage range. This low voltage can cause erratic behavior or non-operation of components that rely on the 24V supply, potentially leading to incorrect sensor readings or control issues.
