Consult the paragraphs “Faults, causes andremedies” on page 95 and “Faults signalled on the display” on page 98 where the possible causes of the mainfaults are listed.Further information on the Ekip Touch trip unit and on the accessories mentioned in this chapter and which arenot covered in this manual are available on the web site http://www.abb.com/abblibrary/DownloadCenter/,with the Ekip Touch manual 1SDH001316R0002.
