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 36.
• 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.

Alarms displayed and A list of faults that may appear on the Ekip Touch display is given below along with suggestions on how to
suggestions resolve them:
Signal Suggestions
Numerical alarm (e.g. Internal error; contact ABB if this typoe of error occurs
30002)
Battery low Change the battery (See 1SDH001000R0509 kit sheet)
Unit on with auxiliary supply, Local Bus parameter enabled but connection
to modules not present, incorrect or communication lost (for more than five
Local bus seconds); check:
• connection and powering of modules in terminal box or external
• that the moldules connected are compatible with Ekip Touch
CB undefined Check the circuit-breaker status signal contacts
CB has failed to open and/or current still present after a TRIP command:
Trip fail command (BF) comply with the procedure proposed in the next chapter 'Faults, causes and
remedies'
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
Configuration • If present, protection parameters do not conflict with size of current of unit
details on page 20 51)
• 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
Problem of Ekip Com Hub module with: certificates, connected devices,
Ekip Com Hub missing Com modules (RTU or with Ethernet connection), API TLS device, Hub
events, parsar configuration
Fault in Ekip Link module: check for loss of connection with one or more actors
Ekip Link Bus
(modules) connected to Link Bus
Ekip Sign 3T connection Alarm for connection of one or more analog inputs to Ekip Signalling 3T module
One or more thresholds of the Ekip Signalling 3T module has/have been
Ekip Sign 3T threshold
exceeded
Internal error Internal error; contact ABB if this typoe of error occurs
Fault with Ekip Com modules: synchronization problem of SNTP
SNTP error
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
Ekip Com module detected with incorrect / not allowed MAC address, contact
MAC Address
ABB.
