4. Product Introduction

The ABB REM615E (Ordering Code: HBMBCAAJABC1BNN11G) is a dedicated motor protection and control IED from ABB’s Relion® 615 series, designed specifically for the protection, control, measurement, and monitoring of asynchronous motors in manufacturing, processing industries, and utility applications.The Relion 615 series represents ABB’s compact, cost-effective protection platform that brings substation-grade protection technology to distribution and motor applications. The REM615E variant is optimized for motor-specific protection requirements, offering comprehensive coverage against electrical and thermal faults.Key Features:

• Comprehensive Motor Protection: Includes thermal overload protection with accurate motor thermal modeling, stall protection during start-up and running, start-up supervision (excessive start time, locked rotor), and negative sequence protection for unbalanced conditions.
• IEC 61850 Native: Built from the ground up to support IEC 61850 Edition 2, enabling seamless integration into modern digital substations and smart industrial networks. Supports GOOSE messaging for high-speed interlocking and control schemes.
• RTD Temperature Monitoring: Supports direct connection of RTD sensors (Pt100, Pt1000, Ni100) for accurate stator and bearing temperature monitoring, providing an additional layer of thermal protection.
• Start-up Supervision: Monitors motor start-up parameters including start time, start current, and number of starts per hour to prevent damage from excessive or prolonged starting.
• Compact Design: The 615 series offers a space-saving form factor ideal for motor control centers (MCCs) and compact switchgear installations.
• Advanced Diagnostics: Features extensive self-monitoring, condition monitoring, and disturbance recording capabilities to aid in predictive maintenance and root cause analysis.
• Cybersecurity: Designed with “security by design” principles, complying with IEC 62351 standards to protect against cyber threats.

Ordering Code Breakdown (HBMBCAAJABC1BNN11G):
The ordering code defines specific hardware and software configurations:

• HB: Product family identifier (Relion 615 Motor Protection)
• M: Motor protection application
• B: Auxiliary voltage range (typically 110-250V DC/AC)
• C: Current input rating (1A or 5A)
• AA: Communication interface configuration (IEC 61850 + Serial)
• J: Front connector type
• ABC: Function package / protection feature set
• 1BNN: Software version / regional customization

The REM615E is configured entirely via the PCM600 software suite, offering intuitive graphical configuration, setting management, and real-time monitoring. We supply genuine new surplus units with full factory documentation and configuration files.

5. Troubleshooting Quick Reference

Closing Suggestion: For complex issues involving protection logic or communication protocols:

1. Export the Disturbance Record and Event Log via PCM600.
2. Capture the Configuration File (.IED) from PCM600.
3. Provide these files to technical support for detailed analysis.
   Our engineers can typically diagnose communication or logic issues within 2 hours using these data points.

6. Frequently Asked Questions (FAQ)

Q1: What is the difference between REM615, REF615, and REG615?A: All are part of the Relion 615 series but optimized for different applications:表格

Choose REM615 for motor applications (pumps, fans, compressors), REF615 for distribution feeders, and REG615 for generator protection.Q2: What does the ordering code “HBMBCAAJABC1BNN11G” specifically indicate?A: ABB ordering codes define specific hardware and software configurations:

• Auxiliary Voltage: Defined by the “B” position (e.g., 110-250V DC/AC wide range)
• Current Input: Defined by “C” position (1A or 5A CT secondary)
• Communication: “AA” indicates IEC 61850 + Serial ports (RJ45 + RS485)
• Function Package: “ABC” defines the protection function set enabled
• Software Version: “1BNN” indicates firmware version and regional settings
• Hardware Revision: “11G” indicates the hardware generation

Recommendation: When replacing, try to match the full ordering code exactly. If substituting with a different code, verify the auxiliary voltage, current input, and communication interfaces first.Q3: Does the REM615E support IEC 61850 communication?A: Yes. The REM615E natively supports IEC 61850 Edition 2, including:

• MMS (Manufacturing Message Specification): For client-server communication with SCADA/DCS.
• GOOSE (Generic Object Oriented Substation Event): For high-speed peer-to-peer communication (trip signals, interlocking).
• SCL (Substation Configuration Language): For system configuration and integration.

This enables seamless integration into modern digital substations without requiring external communication gateways.Q4: What software is used to configure the REM615E?A: The ABB PCM600 (Protection and Control Manager 600) software is the standard engineering tool. It provides:

• Intuitive graphical configuration of protection functions.
• IEC 61850 system configuration (SCL file handling).
• Real-time monitoring and testing.
• Disturbance record analysis.
• Firmware management.
• Setting comparison and documentation.

PCM600 is compatible with Windows 10/11 and supports all Relion 615/670 series devices.Q5: How does the thermal overload protection work in REM615E?A: The REM615E uses a sophisticated thermal model that calculates the motor’s thermal capacity usage in real-time:

• Heating Curve: Based on motor current (including negative sequence for unbalanced heating).
• Cooling Curve: Different time constants for running and stopped conditions.
• Thermal Memory: Remembers thermal state across power interruptions.
• RTD Integration: Can combine thermal model with direct RTD temperature readings for enhanced accuracy.
• Alarm and Trip: Separate thresholds for thermal alarm (warning) and thermal trip (protection).

This ensures accurate protection against overload conditions while maximizing motor utilization.Q6: What motor start-up supervision features does the REM615E offer?A: The REM615E provides comprehensive start-up supervision:

• Start Time Supervision: Trips if start exceeds configured maximum time.
• Locked Rotor Protection: Detects failure to accelerate during start.
• Start Counter: Tracks number of starts per hour/day to prevent excessive starting.
• Start Inhibit: Blocks start if motor is too hot or start limit reached.
• Restart Delay: Enforces minimum time between consecutive starts.

These features protect motors from damage due to frequent or prolonged starting conditions.Q7: What is the warranty and support status for REM615E?A: As a current-generation product, the REM615E is fully supported by ABB with long-term availability guarantees.

• Warranty: We provide a 12-month warranty on our New Surplus units (covering hardware defects).
• Support: Full access to ABB technical documentation, firmware updates, and software tools.
• Lifecycle: Expected service life exceeds 15-20 years with ongoing support.
• Spare Parts: Individual modules and components available for repair.

Q8: Can the REM615E be used for synchronous motor protection?A: The REM615E is primarily designed for asynchronous (induction) motors. For synchronous motors, consider:

• REM615 with Synchronous Package: Some variants include synchronous motor-specific functions (loss of field, pole slip).
• REG615: For large synchronous motors/generators, the generator protection relay may be more appropriate.

Please consult with our engineers to verify suitability for your specific motor type and application.Q9: How do I backup settings for an REM615E?A: Settings backup is straightforward via PCM600:

1. Connect: Establish communication with the relay (Ethernet or Serial).
2. Read: Use “Read from IED” function in PCM600.
3. Save: Export the configuration as an .IED file.
4. Document: Generate setting reports in PDF/Excel format.

For emergency backup, you can also:

• Export individual setting groups.
• Print settings from the local HMI (if equipped).
• Save disturbance records and event logs separately.

Recommendation: Maintain regular backups after any setting changes and store copies off-site.Q10: Do you provide technical assistance for setting calculations?A: Yes. Our team includes engineers experienced with ABB Relion series relays. We can assist with:

• Motor Data Entry: Verifying nameplate data and CT/VT ratios.
• Thermal Model Settings: Calculating thermal time constants and overload curves.
• Start Supervision: Setting appropriate start time and current limits.
• Protection Coordination: Ensuring proper coordination with upstream/downstream devices.
• IEC 61850 Configuration: GOOSE mapping and SCL file integration.

Please provide your motor nameplate data, single-line diagram, and protection requirements for specific advice.
