Event message:
Restricted Battery Stack Startup
Explanation:
The system has entered an error state and has been blocked due to multiple consecutive automatic startup errors. To protect the devices, automatic starts will not be attempted. Manual intervention is required for troubleshooting and to resolve this condition.
Corrective measures:
Startup errors are normally caused by the following:
The voltage difference between P+ and B+ did not reach the set target value during the pre-charging phase.
The main contactor or the pre-charging contactor not engage properly or gave a different feedback signal.
Troubleshooting should be carried out according to the specific cause. Once internal problems have been resolved, a manual restart is required to fix the error and enable automatic system startup again.
