4 Alarm and fault messages

4.1Fault handling

4.1.1Fault types

There are two different types of fault, i.e. plant faults and operational faults. Plant faults are caused by malfunctioning of an inverter component, while operational faults occur as a result of unexpected external influences or logical conditions of the control software.

Examples of plant faults:

F48

F65

F97

Examples of operational faults:

F94

F96

It is however possible for an operational fault to be caused by a defective component. Example: Fault 96 can be caused by a defective capacitor or transformer at the AC output.

4.1.2Fault display / messages

Faults are displayed at the following locations:

Inverter control panel

Control panel in PPsolar

S7 software modules

WinCC

Fault messages are transferred to the following locations:

FAX Alarm

WEB’log

WinCC

Sequential faults: In some cases, the first fault can trigger further sequential faults which are superimposed on the first fault or overwrite it on the display.
