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 6.
• 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
With Vaux present and local Bus enabled: no module detected on
terminal box by trip unit (with alarm icon) or loss of communication for
more than 5 seconds between trip unit and previously detected module
(with prealarm icon)
TC disconnected
Trip coil not connected
L1 Sensor
Current sensor not connected
L2 Sensor
L3 Sensor
Ne Sensor
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
CB state incorrect (esample: current present but CB in open state)
Rating Plug Installation
Rating Plug not installed
Battery low
Battery low or absent
Measuring Installation
Ekip Measuring module not installed
Measuring 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
