An event about the fault is stored as a message on the WHMI. The text Internal Fault with an additional text message, a code, date and time, is stored to indicate the fault type.
Different actions are taken depending on the severity of the fault. The merging unit tries to eliminate the fault by restarting. After the fault is found to be permanent, the merging unit stays in the internal fault mode. All other output contacts are released and locked for the internal fault. The merging unit continues to perform internal tests during the fault situation.
The internal fault code indicates the type of internal fault. When a fault appears, the code must be recorded so that it can be reported to ABB customer service.
