Section 16

Fault tracing and repair

About this chapter

This chapter describes how to carry out fault tracing and if necessary, a change of
circuit board.

16.1

Fault tracing

16.1.1

Information on the local HMI

If an internal fault has occurred, the local HMI displays information under

Main

menu/Diagnostics/IED status/General

Under the Diagnostics menus, indications of a possible internal failure (serious
fault) or internal warning (minor problem) are listed.

Indications regarding the faulty unit are outlined in table

Table 27:

Self-supervision signals on the local HMI
