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:

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)

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)
