Product Introduction

Motor unexpected trips cause costly downtime in continuous process plants. Improper protection settings may lead to winding burnout or mechanical damage under locked rotor and unbalanced load conditions.

ABB REM615 HCMJAEADABC2BNN11E belongs to the Relion 615 platform, developed specifically as all-in-one protection equipment for asynchronous motors. It covers complete motor-specific protection algorithms including thermal overload model, startup supervision and stall protection.

The unit supports flexible signal matrix configuration, allowing engineers to adjust logic without extra hardware modification. Integrated disturbance recorder stores fault waveforms in COMTRADE format for post-fault analysis. Wide communication protocol compatibility enables seamless connection with substation SCADA and DCS systems. This relay sees widespread deployment in mining, chemical, water treatment and metallurgy facilities.

Installation & Configuration Guide

Pre-Installation Preparation (15 mins)

⚠️ Safety Requirements

Carry out lockout-tagout procedures. Cut motor primary circuit power and relay auxiliary supply. Maintain minimum 5 minutes waiting time for voltage discharge on CT/PT circuits.

Tool List

ESD wrist strap, PH1 screwdriver, digital multimeter, mobile phone for wiring and screen capture.

Preparation Work

Connect via PCM600 software and export complete parameter setting group.
Photograph all binary input/output wiring, CT polarity terminals and front panel layout.
Record existing signal matrix, protection curves and communication IP settings.

Old Relay Removal (12 mins)

Step 1: Mark every control wire, CT secondary cable and communication cable with unique labels.

Step 2: Disconnect communication cables first, then open secondary circuit terminals. Never open CT circuit under live status.

Step 3: Unlock front panel latch, pull the inner withdrawable unit out steadily. Avoid sharp tilt to prevent PCB damage.

Step 4: Inspect base unit terminals for oxidation or carbon traces. Clean dust using dry compressed air.

New Relay Installation (18 mins)

Step 1: Wear anti-static protection before unpacking. Mainboard signal chips are sensitive to electrostatic discharge.

Step 2: Confirm complete ordering code REM615 HCMJAEADABC2BNN11E matches original specification. Different suffix codes carry different I/O layouts.

Step 3: Insert the withdrawable unit horizontally into base socket until mechanical locking clicks.

Step 4: Recover wiring strictly following photos. Verify CT polarity and earth connection again before tightening terminals.

Self-Check List

CT secondary loop closed completely ✅

All communication cables fixed properly ✅

No loose terminal connections ✅

Relay unit fully locked inside base ✅

Power-On & Commissioning (30 mins)

Pre-power inspection: Confirm no short circuits on auxiliary supply and signal loops.

Step 1: Switch on auxiliary power and wait for relay initialization process.

Step 2: Launch PCM600 software, establish online connection with the new REM615.

Step 3: Import saved parameter set and verify protection characteristic curves.

Step 4: Test binary input and output channels by simulating switch status signals.

Step 5: Run motor no-load startup test, observe current balance and protection alarm status.

Step 6: Keep continuous running observation for minimum 30 minutes, confirm no unexpected warning codes.

Step 7: Update site maintenance log with relay serial number and replacement date.

Troubleshooting Tip: Communication offline after replacement usually comes from mismatched IP address or wrong network VLAN configuration, not hardware defect.

Quality Inspection Process

Incoming Visual Inspection

Check model marking, housing integrity, no scratch, disassembly traces or burnt components.
Power-Up Basic Test

Supply rated auxiliary voltage, verify normal LED startup sequence, confirm no internal short circuit.
Communication Function Test

Build test network to establish PCM600 connection, read hardware information normally.
Parameter Download Test

Import standard configuration to confirm all function blocks can be activated.
Data Archiving

Record serial number, hardware revision and test date for full traceability.
Final Packaging

Place relay into anti-static bag, fill bubble cushion, attach QC passed shipping label.

Field Replacement Pitfall Guide

❗ Suffix Code Matching Risk

REM615 has dozens of ordering variants. HCMJAEADABC2BNN11E defines I/O quantity, display type and communication hardware. Partial model matching will cause unavailable terminals.

❗ CT Secondary Safety Rule

Always short-circuit current transformer terminals before disconnecting wiring. Open CT circuit generates dangerous high voltage.

❗ Parameter Version Conflict

If the new relay firmware version differs greatly, some old configuration files cannot be imported directly. Export .cid file and recompile in PCM600.

❗ Ignoring Static Protection

Unprotected handling causes invisible partial hardware failure. Intermittent tripping faults may emerge weeks after commissioning.

❗ Motor Startup Parameter Calibration

Each motor has unique startup characteristics. Copying relay settings blindly may trigger false startup timeout protection.

❗ Cable Separation Rule

Run CT wiring separately from power cables. Electromagnetic interference leads to distorted current sampling values.

Frequently Asked Questions (FAQ)

What equipment can REM615 HCMJAEADABC2BNN11E protect?

It is designed for asynchronous motors, widely used for pumps, fans, conveyors and crushers in industrial distribution networks.
Does this relay support hot swapping?

The withdrawable unit can be pulled out only after cutting auxiliary power. Hot swap operation is not permitted.
Which software is required for parameter setting?

ABB PCM600 is the official configuration tool. Generic third-party software cannot access full protection logic settings.
Can it realize arc flash protection?

This specific variant supports arc protection function if matched with external light sensors; confirm demand before ordering.
Is direct replacement available for old REM615 units?

It depends on full ordering code. If suffix strings differ, terminal allocation and onboard functions may change.
What warranty is offered for stocked units?

All available relays carry a 12-month warranty. Damage caused by miswiring, surge voltage and ESD abuse is not covered.
Can fault recording data be exported?

Yes. Waveform records support COMTRADE format export for off-line fault analysis.
