Status diagnosis and repair

Service-Codes Displayed

Your FRONIUS IG unit is equipped with a self diagnostic system which
automatically identifies a large number of possible defects by itself and
displays them on the screen. It is thus possible to quickly ascertain de-
fects in the FRONIUS IG unit, in the photovoltaic system as well as instal-
lation and operation errors.

Whenever the self diagnostic system has identified a particular defect, the
respective service code is displayed on the screen.

Note! Display of a service code for a short time may be a result of
the control procedure of your FRONIUS IG unit. If subsequently it
continues to operate normally, there has not been a case of an
error.

Service dis-
play

starts synchronizing the network (display shows „SYNC

“).

General ser-
vice codes

As long as the no load voltage of the solar modules is not sufficient, the
screen displays the information „DC

LOW

“.
