FAULT TRACING
The fault codes, their causes and correcting actions are presented in Table 11-2 below. The
converter has an internal memory for storing the converter status at the time of fault as well as
additional information about the source of the fault. This feature is intended to help the user or the
service personnel to determine the cause of fault.
11.1 Fault time data record
When a fault occurs a fault code is displayed on the keypad. By pushing the
Menu button right
here
you will enter the
Fault time data record menu
indicated by T.1 T.16. In this menu, some selected
important data valid at the time of the fault are recorded.
