Event E017

Qualified person

Event message:

  • BCMU Sleep

Explanation:

The Battery Control Management Unit (BCMU) has been put into energy-saving mode manual by the "Power" button being pressed down and held. This device will cease operation, thereby switching off the battery cluster it manages from the system. As a result, the system has entered an error state.

Corrective measures:

  • Locate the “Power” button on the respective battery cluster and press and hold it down for more than three seconds to attempt to wake the BCMU and exit sleep mode.

  • Backup solution: If the method described above fails, disconnect and reconnect the DC circuit breaker of the battery cluster. Completely switching the device off and on again forces the BCMU to initialize and resume normal operation.

  • Once the BCMU has been successfully woken up or restarted, it automatically exits sleep mode and the system error alarm is cleared accordingly.
