Protections
In the event of protection or measurement alarms, the associated signals are reported:
Signal
Trip Test
Protection timing (for example: L
timing)
Protection prealarm (for example:
Prealarm G)
Protection (Trip off) [for example: S
(Trip off) ]
2I Protection Active
Load LC1 / Load LC2
Iw1 Warning / Iw2 Warning
Harmonic dist.
Power factor
Phase cycle
Frequency
5th harmonic above Th / I sopra Th
/ THD I above Th / THD V above Th
to resolve them are given below. Integrate the table with that of the circuit-breaker available in manuals
1SDH000999R0002 and 1SDH001000R0002.
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
Communication
Circuit-breaker in withdrawn position,
problems with
Vaux absent or modules not inserted
modules in terminal
properly
box
CB status not aligned Absence of terminal box modules or of
with CB position contact S75I
The connections or supplies of the
opening/closing actuators are not
correct
Circuit-breaker fails
to react to opening/ Absence of auxiliary power supply to
closing command
Ekip Touch
from Ekip Touch
Circuit-breaker is in a condition which
fails to enable the selected command
No auxiliary supply or currents lower
Display off and/or not
than minimum turn-on values
backlit
Temperature outside range
Type of alarm
Trip test performed signal. Press iTEST to reset the message
Specific protection in time delay mode
Specific protection in prealarm
Specific protection, configured with trip disabled, in alarm state
2I Protection active
Current threshold 1 I1 / 2 I1 exceeded and in alarm state
Current threshold Iw1 / Iw2 exceeded and in alarm state
Harmonic Distortion protection in alarm state
Power factor measurement (cos φ) less than set threshold
Phase sequence protection in alarm state
Frequency measured off range (<30 Hz or >80 Hz)
Single or total harmonic measurement above threshold
Suggestions
Insert modules, set CB to Connected
position, connect Vaux
Check for presence of terminal box
modules and connect contact S75/I
Check connections and supplies.
Check supplies and status of Power
LEDs
Check circuit-breaker documentation
and cases that fail to enable command
Correct operating condition.
Correct operating condition.
