Function Features
- Comprehensive and Targeted Motor Protection
It is equipped with an enhanced thermal model that uses resistance temperature detector bias and negative sequence current compensation to prevent rotor heating. It provides overvoltage, undervoltage, overfrequency and underfrequency protection, and the current unbalance protection threshold can be adjusted between 4% – 30%. It can quickly detect locked rotor and mechanical jamming faults and trigger tripping actions immediately, and also provides directional ground overcurrent protection to cover all potential fault points of the motor.
- Precise Metering and Complete Data Recording
It can conduct real-time metering of multiple electrical parameters such as motor current, voltage, power, energy and frequency, and monitor temperature parameters up to 200°C. It can capture 16-cycle oscillographic data when a fault trip occurs or a manual command is issued. It can store the last 512 event records, including motor start-up times, trip causes and thermal capacity usage, providing a full data basis for fault analysis.
- Flexible Communication and Remote Management
It supports multiple communication protocols including Modbus RTU, Modbus TCP/IP and Profibus DP. It is equipped with Ethernet connectivity and RS232/RS485 communication interfaces, and supports 1ms precision IRIG-B time synchronization for event logging. Users can use EnerVista software to remotely configure parameters, update firmware and retrieve data, realizing centralized monitoring and management of motors.
- User-Friendly Operation and Intelligent Diagnosis
It is equipped with a 40-character liquid crystal display and a keypad operation interface, and LED indicators can clearly show the motor’s stop, operation and overload status. It can automatically generate motor health reports, analyze historical operation data to predict maintenance needs, and send early warnings for problems such as broken belts and pump suction loss, reducing troubleshooting time.
