KPS Intermediate Circuit Charging Circuit Defective

What does Intermediate circuit charging circuit defective PMx mean?

The optocoupler responsible for ballast resistor current detection signals that no current is flowing through the ballast resistor, even during charging. This indicates a defect in the intermediate circuit charging circuit of the KPS module (PMx).

• KPS intermediate circuit charging circuit is defective.
• Failure within the KPS power supply's charging module.
• Internal component failure affecting the charging circuit's operation.
