Messages
A distinction is made between alarm messages and warning messages
Alarm
Power operation is automatically shut off if serious errors occur. The PCS switches to the alarm state and outputs an alarm message. Power operation can only be restarted after the cause of the alarm has been removed and the alarm message has been reset
Warning
In case of less severe faults, the power operation is not interrupted, but a warning message is issued.
