Identification of alarms or failures
Introduction
The protection trip unit is able to identify some faults and to signal them through LEDs or display; you need to
identify the cause and eliminate it before re-closing the circuit-breaker, both locally and remotely.
WARNING! identification of the faults must be managed only by Skilled Persons in
the electrical field (IEV 195-04-01): person with relevant education and experience
to enable him or her to perceive risks and to avoid hazards which electricity can
create. Indeed, it may be necessary to perform insulation and dielectric tests on part
or all of the installation.
Some failures involve partial operation of the circuit-breaker. Consult the paragraphs “Faults, causes and
remedies” on page 295 and “Faults signalled on the display” on page 298 where the possible causes of the
main faults are listed.
Further information on the Ekip Touch trip unit and on the accessories mentioned in this chapter and which are
not covered in this manual are available on the website http://www.abb.com/abblibrary/DownloadCenter/,
with the Ekip Touch manual 1SDH001316r0002.
