If an alarm/warning has occurred, refer to this chapter and remove its cause.
13.7.1 Alarms and warning list
When an error occurs during operation, the corresponding alarm or warning is displayed.
If any alarm has occurred, refer to section 13.7.2 and section 8.3; if any warning has occurred, refer to section
