2 - Identification of alarms or failures

Introduction The protection release is able to identify some faults and to signal them through LEDs or the 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 Expert Persons in the

electrical area (IEV 195-04-01: Person with sufficient training and experience to allow him/

her to perceive the risks and to avoid the hazards potentially created by electricity). 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 94 and "Faults signalled on the display" on page 97 where the possible causes of the main

faults are listed.

Further information on the Ekip Touch release and on the accessories mentioned in this chapter and which are

not covered in this manual are available from the web site http://www.abb.com/abblibrary/DownloadCenter/,
