LV 123 10.4.8 - Test: undervoltage

The behavior in the event of undervoltage shall be verified for each controlled HV component. The specifications of Table “HV voltage levels” shall be used.

In the event of undervoltage, operation with the performance specified for the HV operating status B3 shall be verified.

Caratteristiche

Compliance with the HV operating status B3 shall be verified.

The operating behavior of the HV component shall be documented and verified. The test shall be used to verify that the maximum intended performance or the HV operating status B1 is complied with again when the DC HV voltage falls within the range of unlimited operating capability again after a deviating characteristic.

The test shall be used to verify that the maximum intended performance or the HV operating status B2 is complied with again when the DC HV voltage falls within the range of limited operating capability again after a deviating characteristic.

Test criteria for the HV operating status B3:

  • Operational, specified state
  • No fault memory entry if no power demand is present
  • Fault memory entry if there is a power demand
  • Automatic reestablishment of maximum intended performance and of the HV operating status B1 in the event of a return to the range of unlimited operating capability
  • Automatic reestablishment of maximum intended performance and of the HV operating status B2 in the event of a return to the range of limited operating capability
