Protections
In the event of protection or measurement alarms, the associated signals are reported:
Signal Type of alarm
Trip Test Trip test performed signal. Press iTEST to reset the message
Protection timing (for example: L
timing)
Specific protection in time delay mode
Protection prealarm (for example:
Prealarm G)
Specific protection in prealarm
Protection (Trip off) [for example: S
(Trip off) ]
Specific protection, configured with trip disabled, in alarm state
2I Protection Active 2I Protection active
Load LC1 / Load LC2 Current threshold 1 I1 / 2 I1 exceeded and in alarm state
Iw1 Warning / Iw2 Warning Current threshold Iw1 / Iw2 exceeded and in alarm state
Harmonic dist. Harmonic Distortion protection in alarm state
Power factor Power factor measurement (cos
φ
) less than set threshold
Phase cycle Phase sequence protection in alarm state
Frequency Frequency measured off range (<30 Hz or >80 Hz)
5th harmonic above Th / I sopra Th
/ THD I above Th / THD V above Th
Single or total harmonic measurement above threshold
Faults, causes and remedies
A list of possible faulty situations for Ekip Touch, their possible causes and suggestions about how to resolve
them are given below.
NOTE: check error messages on display before consulting the table; if the suggestions given
fail to resolve the problem, call the ABB assistance service and provide the report produced
by the Ekip Connect software if possible
Fault Possible causes Suggestions
Communication
problems with
modules in terminal
box
Circuit-breaker in withdrawn position,
Vaux absent or modules not inserted
properly
Insert modules, set CB to Connected
position, connect Vaux
CB status not aligned
with CB position Absence of terminal box modules or of
contact S75I Check for presence of terminal box
modules and connect contact S75/I
Circuit-breaker fails
to react to opening/
closing command
from Ekip Touch
The connections or supplies of the
opening/closing actuators are not
correct
Check connections and supplies.
Absence of auxiliary power supply to
Ekip Touch Check supplies and status of Power
LEDs
Circuit-breaker is in a condition which
fails to enable the selected command Check circuit-breaker documentation
and cases that fail to enable command
Display off and/or not
backlit
No auxiliary supply or currents lower
than minimum turn-on values
Correct operating condition.
Temperature outside range Correct operating condition.
Measurements
incorrect or absent
(current, voltage, etc)
Current below the minimum threshold
that can be displayed
Correct operating condition.
Incorrect frequency setting Set frequency
Harmonic distortion and/or crest factor
off range
Correct operating condition.
Rated Voltage parameter setting error Set the correct parameters
