ABB Emax2 Ekip (E4.2) Lista de códigos de falla & Communication Commissioning Guide

Applicable to Ekip Dip / Tocar / 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

1. LED Alarm Indications (Common to all Ekip units, for on-site quick diagnosis)

Amarillo (Advertencia)

Encendido fijo: 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

Rojo (Alarm/Trip)

Encendido fijo: Protection activated & tropezó, trip command issued

Fast flashing: Sensor disconnection, trip coil open circuit, BF trip failure, protection timing fault

2 flashes every 2s: Rating plug damaged

Amarillo + Red fast flashing: Communication lost between main trip board and protection timing module

Amarillo + Red slow flashing: Critical internal trip unit fault, contact ABB service

2. On-screen Alarm & Lista de códigos de falla (Touch/Hi-Touch)

🔹 Protection Trip Events (Trip log, check first)

🔹 Hardware / Communication Alarms (Fault alarms, not trips)

Event storage: Touch/Hi-Touch stores up to 200 latest events, with timestamp, fault current and voltage exportable; Ekip Dip has no event storage

3. 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: velocidad en baudios 19200, Incluso paridad, 1 bit de parada, 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

Fuente de alimentación: Ekip Com requires 24V DC auxiliary supply (Vaux). Module will not run without 24V!

3.2 Herramientas de puesta en marcha

1. Ekip Connect (ABB official, privilegiado): Parameter read/write, bus scan, event export, IP/slave address modification, actualización de firmware, iTEST; supports direct connection via USB T&P test head, independent of field bus
2. Modbus master tools: Modscan, Modbus Poll, SOCIEDAD ANÓNIMA (siemens, Schneider etc.)

3.3 Commissioning Steps for RTU RS485

1. Apagar, mount Ekip Com Modbus RTU module, connect W1(A) W2(B), feed 24V DC to module; fit 120Ω terminators at bus ends
2. Encendido, on trip unit screen: Settings → Communication → Modbus RTU

Enable bus

Set slave address (1~247, unique per bus segment)

Match baudrate & parity with master

3. Connect PC USB-RS485 adapter: A→W1, B→W2; common ground is critical
4. Ekip Connect → Scan → Serial → Configure COM port, baudrate, even parity → Start scan
5. Device found: Read measurements (I/U/P), breaker status, alarmas; write operations require password authority
6. No device found troubleshooting:

Confirm 24V supply; W1/W2 polarity; terreno común; terminator; abordar el conflicto; baud/parity mismatch

Confirmar “Local bus enabled” on trip unit screen

3.4 Commissioning Steps for Modbus TCP

1. Mount Ekip Com Modbus TCP module, supply 24V DC, connect Ethernet to switch
2. On trip unit screen: Settings → Communication → Modbus TCP

DHCP: Enable/Disable; set static IP, subnet, puerta

Enable Modbus TCP service (Puerto 502)

3. Keep PC and module on same subnet, direct cable or via switch
4. Ekip Connect → Scan → Ethernet; or open module IP in browser for read-only web page
5. PLC/SCADA access: Modbus TCP port 502, refer to ABB Ekip Modbus register map

3.5 Access Rights & Contraseña

Read measurements & alarmas: No password required

Modify protection settings, parámetros de comunicación, clear events: Engineer password (por defecto 000000)

iTEST trip test: Local operation only at connected position; remote test trigger blocked

3.6 Common Communication Pitfalls (E4.2N4000R4000)

1. Missing 24V auxiliary supply: Com module fails to start. CT self-power only supports protection logic, cannot power Com module
2. Ungrounded RS485 bus: Intermittent packet loss and garbled data; single-point grounding for long-distance bus
3. Ekip G Touch has integrated gateway. Do not use together with external Ekip Com, bus conflict will occur
4. Withdrawable breaker: Bus connection inside the cradle is disconnected in test position; communication only available in connected position
5. Modbus register types: Input registers (read-only: actual, Voltaje, estado); Holding registers (read/write: settings, control). Remote open/close requires additional Ekip Com Actuator module; standard Com module is read-only, cannot execute remote switching
6. Reset Rules
7. Protection trips (L/S/I/G): Clear fault first, then reset locally (screen reset or remote reset via YR contact)
8. Warning alarms (low battery, SNTP error): Auto clear after root cause removed or manual acknowledge
9. BF trip failure alarm: Mechanical inspection on-site required, manual confirmation to clear alarm
