Signal Suggestions
Configuration
Protection parameter configuration error: make sure that threshold I4 and time t4 are
compatible with the minimum values required for self-supply
Check:
•
Rating plug
of model compatible with Ekip Touch and CB size
• If present, protection parameters do not conflict with size of current of unit details
on page 42)
• In the absence of
Vaux threshold I4 and/or I41 > 100 A
• In the absence of Vaux time t4 and/or t41 > 100 ms
• RC protection active and
Rating Plug
not RC
Invalid Date Wrong date and time: set in Settings-System-Date and Settings-System-Time

configuration = Normal
Ekip Com Hub
Problem of Ekip Com Hub module with: certificates, connected devices, missing
Com modules (RTU or with Ethernet connection), API TLS device, Hub events, parsar
configuration
Ekip Link Bus
Fault in Ekip Link module: check for loss of connection with one or more actors
(modules) connected to Link Bus
Ekip Sign 3T
connection
Alarm for connection of one or more analog inputs to Ekip Signalling 3T module
Ekip Sign 3T
threshold
One or more thresholds of the Ekip Signalling 3T module has/have been exceeded
Internal error Internal error; contact ABB if this typoe of error occurs

Fault with Ekip Com modules: synchronization problem of SNTP synchronization
reference module
Measuring Error Measurement module parameter reading error, contact ABB
Ethernet
disconnected
No external cable on one or more Ekip Com modules with Ethernet connection
IEEE1588 synch Synchronization problem of IEEE 1588 synchronization reference module
MAC Address
Ekip Com
module detected with incorrect / not allowed MAC address, contact ABB.
Ekip Installation Installation error between HMI and Mainboard, contact ABB
Measuring
installation Install Measurement module ( Settings-Circuit breaker-Installation-Measuring-Install )
menu
RatingPlug
Installation Install Rating Plug ( Settings-Circuit breaker-Rating Plug-Install menu) and check
connection if there are further faults
Maintenance
Maintenance alarm: carry out maintenance and then reset the alarm via Ekip Connect
(see page !da duplicazione!112)
Rating plug Rating plug not present, value or size incompatible with Ekip Touch parameters
Zone Selectivity
Diag
Error in zone selectivity connections (Hardware Selectivity)
S.G.R. Toroid Check connection and state of toroid
Sensor L1/L2/
L3/Ne Fault in connection of sensors to Trip unit; check status of sensors, including external
Neutral, or call ABB
Configuration
Session TFTP server enabled and/or configuration session open on module Ekip Com
IEC61850 or Ekip Hub
Software Not
Compatible
The software versions between Mainboard and display (Ekip Touch) are not compatible
with each other: To restore compatibility, please consult ABB.
NOTE :
modification of all parameters is inhibited via display; if present,
protections L, I and Iinst are active and function with the parameters prior to the
alarm (parameters of previous unit are active if display has been replaced)
CB status CB state incorrect (esample: current present but CB in open state)
Switchboard Actor
communication Error
Check configuration and connection of Ekip Link module
TC disconnected
Disconnection of Trip coil detected, check functionality
Check Trip coil, status of the terminal and cables connecting to Ekip Touch
Contact Wear Make sure that the contacts/poles are in good condition.
