Alarms and signals
Alarm Tests
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.
Self-diagnosis
Ekip Touch continuously monitors its own operating state and that of all connected devices.
In the event of an error, the detected fault is reported:
Signal Description
Local Bus Local Bus enabled but no module detected on the terminal box
TC disconnected Trip coil not connected
L1 Sensor Current sensor not connected
L2 Sensor Current sensor not connected
L3 Sensor Current sensor not connected
Ne Sensor Current sensor not connected
Gext Sensor Toroid S.G.R. not connected
Rating Plug
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 Internal error
Invalid Date Date not set
CB status Error on CB status contacts
RatingPlug installation Rating Plug not installed
Battery low Battery low or absent
Measuring installation Ekip Measuring module not installed
Measuring Error Ekip Measuring module in error
Software Not Compatible
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.
Configuration
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
2
(in case of UL circuit-breaker)
NOTE: for resolution of the signals see section Fault resolution on page 294.
