For further information on internal relay faults, refer to the Operator’s Manual.
Warnings
In case of a warning, the relay continues to operate except for those protection
functions possibly affected by the fault, and the green target LED (ready) remains lit
as during normal operation. Further, a fault target message, which depending on the
type of fault includes a fault code, appears on the LCD. If more than one type of
