Putting into service and maintenance

2 - Identification of alarms or failures

Faults, causes and remedies

The following is a list of possible fault situations, their possible causes and suggestions for resolving
them.

NOTE:

with Ekip Touch, also make use of the suggestions given in document

1SDH001316R1002

Faults

Possible causes

Suggestions

The circuit-breaker
doesn't close when the
closing pushbutton is
pressed

The trip signal of the protection trip
unit has not been reset

Press the TU mechanical reset
pushbutton or operate the electrical
reset remotely.

The open-position key lock or
padlock is activated

Unlock the lock in open position
using the relevant key

The circuit-breaker is in an
intermediate position between
connected and isolated for test
or between isolated for test and
disconnected

Complete the rack-in operation

The undervoltage coil is not
energized

Check the power supply circuit and
the power supply voltage

The opening coil is permanently
energized

Correct operating condition.

The trip unit pushbutton is pressed
(withdrawable version)

Rotate the crank to complete

The circuit-breaker
doesn't close when the
closing coil is powered

The trip signal of the protection trip
unit has not been reset

Press the TU Reset button

The power supply voltage of the
auxiliary circuits is too low

Measure the voltage: it should not
be lower than 70% of the rated
voltage of the coil

The power supply voltage is
different from that indicated on the
rating plate

Check the voltage on the rating
plate

The cables of the coil are not
inserted correctly in the terminals

Make sure there is continuity
between cable and terminal and if
necessary reconnect the cables of
the coil to the terminals

The connections in the power
supply circuit are wrong

Check the connections using the
relevant wiring diagram

The closing coil is damaged

Replace the coil

The operating mechanism is
blocked

Perform the closing operation
manually; if the fault persists
contact ABB

The open position key lock is
activated

Unlock the lock in open position
using the relevant key

The circuit-breaker is in an
intermediate position between
connected and test or the trip
unit pushbutton is pressed
(withdrawable version)

Complete the rack-in operation

The undervoltage coil is not
energized

Make sure that undervoltage coil is
energized properly

The opening coil is permanently
energized

Correct operating condition. If
necessary, disconnect the power
from the opening coil

The racking out crank handle is
inserted (withdrawable version)

Remove the crank

The circuit-breaker
doesn't open when the
opening pushbutton is
pressed

The operating mechanism is
blocked
