ABB Emax2 Ekip (E4.2) 오류 코드 목록 & Communication Commissioning Guide
Applicable to Ekip Dip / 만지다 / 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)
노란색 (경고)
계속 켜져 있음: 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
빨간색 (알람/트립)
계속 켜져 있음: Protection activated & tripped, trip command issued
Fast flashing: Sensor disconnection, trip coil open circuit, BF trip failure, protection timing fault
2 flashes every 2s: Rating plug damaged
노란색 + Red fast flashing: Communication lost between main trip board and protection timing module
노란색 + Red slow flashing: Critical internal trip unit fault, contact ABB service
- On-screen Alarm & 오류 코드 목록 (Touch/Hi-Touch)
🔹 Protection Trip Events (Trip log, check first)
| Display Label | 설명 | 비고 |
| 엘 | Long-time overload trip ANSI49 | 초과 적재, 열 기억, reset after cooling |
| 에스 | Short-time short-circuit ANSI51/50TD | Short-circuit short delay, for selectivity |
| 나 | Instantaneous short-circuit ANSI50 | Instant short-circuit trip |
| G | Ground fault ANSI51N | Only available on LSIG versions |

| 단계 | 위상 순서 오류 | Phase sequence protection activated |
| THD V / THD I | Harmonic distortion excess | Hi-Touch harmonic monitoring |
| MCR | Closing short-circuit protection | Short-circuit at closing instant |
🔹 Hardware / Communication Alarms (Fault alarms, not trips)
| Alarm Text | 오류 설명 | 문제 해결 |
| 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, 버스 터미널, module compatibility |
| 배터리 부족 | RTC backup battery depleted | Replace CR2450 battery kit, reset date/time after replacement |
| Invalid date | RTC time lost | Settings → System → Date & 시간; enable SNTP sync with Com TCP |
| 구성 오류 | 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, 회로망, 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 | 전원 주기; 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 / 모드버스 TCP)
Communication module types:
Ekip Com Modbus RTU (RS485, 2-wire W1/W2, 모드버스 RTU)
Ekip Com Modbus TCP (이더넷, 모드버스 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
모드버스 RTU: Baudrate 19200, 짝수 패리티, 1 정지 비트, Slave ID 1
모드버스 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
전원공급장치: Ekip Com requires 24V DC auxiliary supply (Vaux). Module will not run without 24V!
3.2 시운전 도구
- Ekip Connect (ABB official, 우선의): Parameter read/write, bus scan, event export, IP/slave address modification, 펌웨어 업그레이드, iTEST; supports direct connection via USB T&P test head, independent of field bus
- Modbus master tools: Modscan, Modbus Poll, PLC (지멘스, Schneider etc.)
3.3 Commissioning Steps for RTU RS485
- 전원 끄기, mount Ekip Com Modbus RTU module, connect W1(에이) W2(비), feed 24V DC to module; fit 120Ω terminators at bus ends
- 전원 켜기, 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, 경보; write operations require password authority
- No device found troubleshooting:
Confirm 24V supply; W1/W2 polarity; 공통점; terminator; address conflict; baud/parity mismatch
확인하다 “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, gateway
Enable Modbus TCP service (포트 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 & 경보: No password required
Modify protection settings, 통신 매개변수, clear events: Engineer password (기본 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: 현재의, 전압, 상태); Holding registers (read/write: settings, 제어). 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
