Ekip Touch provides a series of signals that indicate its operating state, alarms present, or configuration errors
in progress.
The signals are provided:
• By LEDs, as described on page 37.
• By messages on the diagnosis bar.
The messages on the diagnostics bar can be divided into three categories: self-diagnosis, protection or
measurement alarms, and programming error.
In the event of an error, the detected fault is reported:
Signal
Local Bus
TC disconnected
L1 Sensor
L2 Sensor
L3 Sensor
Ne Sensor
Gext Sensor
Rating Plug
Internal Error
Invalid Date
CB status
RatingPlug installation
Battery low
Measuring installation
Measuring Error
Software Not Compatible
Configuration
NOTE: for resolution of the signals see section Fault resolution on page 294.
Description
Local Bus enabled but no module detected on the terminal box
Trip coil not connected
Current sensor not connected

Make sure that one of the following conditions is present:
• Rating plug not connected
• Invalid value
• Rating Plug Rc inserted but Ekip Measuring not present
• Upon replacing the rating plug I4 becomes > 1200 A (in the case of UL
circuit-breaker)
Internal error
Date not set
Error on CB status contacts
Rating Plug not installed
Battery low or absent
Ekip Measuring module not installed
Ekip Measuring module in error
The Mainboard and Ekip Touch software versions are not compatible with
each other: editing of all parameters is inhibited by the display.
The protections L, I and Iinst are active and working with the parameters
set in the previous protection trip unit.
To restore compatibility please contact ABB.
Make sure that one of the following conditions is present:
• I4 < 0.3 In (con In = 100 A), 0.25 In (con In = 400 A) or 0.2 In (for all
other sizes), in the absence of auxiliary power supply
• Iu < (2 * In * I1) if InN = 200 %
• t2 or t4 or t5 or t41 > 0.4 s (in case of UL circuit-breaker)
• I4 > 1200 A (in case of UL circuit-breaker)
• Protection curve L different from t=k/i
