ABB Emax2 Ekip (E4.2) Fault Code List & Communication Commissioning Guide
Applicable to Ekip Dip / Tocco / Hi-Touch / G Touch; Ekip Dip has no screen, only LED alarms; Touch/Hi-Touch support text & numeric fault codes and event logging
Preliminary note: Protection trips (L/S/I/G) are protection events, not hardware faults; 3xxxx numeric codes indicate internal trip unit hardware faults
- LED Alarm Indications (Common to all Ekip units, for on-site quick diagnosis)
Giallo (Avvertimento)
Acceso fisso: Pre-alarm, protection pre-warning, auxiliary signal alarm
2 flashes per 0.5s: Parameter configuration error
Fast flashing: Rating plug mismatched or not properly fitted
Rosso (Alarm/Trip)
Acceso fisso: Protection activated & inciampato, trip command issued
Fast flashing: Sensor disconnection, trip coil open circuit, BF trip failure, protection timing fault
2 flashes every 2s: Rating plug damaged
Giallo + Red fast flashing: Communication lost between main trip board and protection timing module
Giallo + Red slow flashing: Critical internal trip unit fault, contact ABB service
- On-screen Alarm & Fault Code List (Touch/Hi-Touch)

🔹 Hardware / Communication Alarms (Fault alarms, not trips)
| Alarm Text | Descrizione del guasto | Risoluzione dei problemi |
| BF Trip failed command | Trip command sent, breaker remains closed with primary current present | Check YO trip coil, mechanism jamming, mechanical blockage; perform iTEST |
| Local bus | Internal Ekip bus W1/W2/W3/W4 communication lost, expansion module offline | Check Ekip Com / Ekip Signalling module power supply, terminali degli autobus, module compatibility |
| Low battery | RTC backup battery depleted | Replace CR2450 battery kit, reset date/time after replacement |
| Invalid date | RTC time lost | Settings → System → Date & Tempo; enable SNTP sync with Com TCP |
| Errore di configurazione | Conflict between rating plug and protection settings | Verify rating plug; G / I4 threshold cannot exceed 100A without Vaux auxiliary supply |
| Sensor broken wire | Internal CT signal abnormal | Check connection between trip unit and CT; internal failure requires factory repair |
| Trip coil open circuit | YO loop wiring break | Measure YO coil resistance and external wiring |
| SNTP error | NTP time synchronization failed (Modbus TCP module) | Check gateway, network, NTP server address |
| Ekip Com module missing | Communication module not detected | Check module power, bus connector, model compatibility; replace defective module |
| 30002, 30xxx numeric codes | Trip unit firmware / MCU internal error | Ciclo di alimentazione; if fault persists replace trip unit, contact ABB |
| Breaker status unknown | Conflicting feedback from auxiliary contacts | Check auxiliary contact wiring and mechanical position |
Event storage: Touch/Hi-Touch stores up to 200 latest events, with timestamp, fault current and voltage exportable; Ekip Dip has no event storage
- Ekip Communication Commissioning Guide (Ekip Com Modbus RTU / ModBus TCP)
Communication module types:
Ekip Com Modbus RTU (RS485, 2-wire W1/W2, ModBus RTU)
Ekip Com Modbus TCP (Ethernet, ModBus TCP)
✅ Ekip Dip has no native communication. Communication requires Touch/Hi-Touch/G Touch plus optional Ekip Com module
3.1 Factory Default Communication Parameters
ModBus RTU: Baudrate 19200, Anche la parità, 1 fermati un po', Slave ID 1
ModBus TCP: DHCP enabled by default; fallback static IP: 192.168.1.100, mask 255.255.255.0
Bus wiring: RS485 W1=A, W2=B; 120Ω terminating resistor required at bus ends
Alimentazione elettrica: Ekip Com requires 24V DC auxiliary supply (Vaux). Module will not run without 24V!
3.2 Strumenti di messa in servizio
- Ekip Connect (ABB official, preferito): Parameter read/write, bus scan, event export, IP/slave address modification, aggiornamento del firmware, iTEST; supports direct connection via USB T&P test head, independent of field bus
- Modbus master tools: Modscan, Modbus Poll, PLC (Siemens, Schneider etc.)
3.3 Commissioning Steps for RTU RS485
- Spegnimento, mount Ekip Com Modbus RTU module, connect W1(UN) W2(B), feed 24V DC to module; fit 120Ω terminators at bus ends
- Accendere, on trip unit screen: Settings → Communication → Modbus RTU
Enable bus
Set slave address (1~247, unique per bus segment)
Match baudrate & parity with master
- Connect PC USB-RS485 adapter: A→W1, B→W2; common ground is critical
- Ekip Connect → Scan → Serial → Configure COM port, baudrate, even parity → Start scan
- Device found: Read measurements (I/U/P), breaker status, allarmi; write operations require password authority
- No device found troubleshooting:
Confirm 24V supply; W1/W2 polarity; terreno comune; terminator; address conflict; baud/parity mismatch
Confermare “Local bus enabled” on trip unit screen
3.4 Commissioning Steps for Modbus TCP
- Mount Ekip Com Modbus TCP module, supply 24V DC, connect Ethernet to switch
- On trip unit screen: Settings → Communication → Modbus TCP
DHCP: Enable/Disable; set static IP, subnet, porta
Enable Modbus TCP service (Porta 502)
- Keep PC and module on same subnet, direct cable or via switch
- Ekip Connect → Scan → Ethernet; or open module IP in browser for read-only web page
- PLC/SCADA access: Modbus TCP port 502, refer to ABB Ekip Modbus register map
3.5 Access Rights & Password
Read measurements & allarmi: No password required
Modify protection settings, parametri di comunicazione, clear events: Engineer password (predefinito 000000)
iTEST trip test: Local operation only at connected position; remote test trigger blocked
3.6 Common Communication Pitfalls (E4.2N4000R4000)
- Missing 24V auxiliary supply: Com module fails to start. CT self-power only supports protection logic, cannot power Com module
- Ungrounded RS485 bus: Intermittent packet loss and garbled data; single-point grounding for long-distance bus
- Ekip G Touch has integrated gateway. Do not use together with external Ekip Com, bus conflict will occur
- Withdrawable breaker: Bus connection inside the cradle is disconnected in test position; communication only available in connected position
- Modbus register types: Input registers (read-only: attuale, voltaggio, stato); Holding registers (read/write: settings, controllare). Remote open/close requires additional Ekip Com Actuator module; standard Com module is read-only, cannot execute remote switching
- Reset Rules
- Protection trips (L/S/I/G): Clear fault first, then reset locally (screen reset or remote reset via YR contact)
- Warning alarms (low battery, SNTP error): Auto clear after root cause removed or manual acknowledge
- BF trip failure alarm: Mechanical inspection on-site required, manual confirmation to clear alarm
