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.
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
Rating Plug Installation
Battery low
Measuring Installation
Measuring Error
Software Not Compatible
Configuration
Ekip Link Bus
PC Power exceed
IEEE1588 synch
Maintenance
Zone Selectivity Diag
CB undefined
Description
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)
Trip coil not connected
Current sensor not connected
Toroid S.G.R. 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
CB state incorrect (esample: current present but CB in open state)
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
Loss of connection with one or more actors
The average power limit setting of the Power Controller has been
exceeded
Synchronization problem of IEEE 1588 synchronization reference module
Maintenane alarm
Error in zone selectivity connections (Hardware Selectivity)
CB state contacts error
