AMDP-X/F841 series motor protection is a digital motor protection developed and produced by Shenyang Xinwei Automation Co., Ltd., which has functions such as lack of phase, short circuit, grounding, stall, overload, unbalanced current, underload, overvoltage and undervoltage. It is suitable for AC voltage not exceeding 1140V and frequency of 50Hz or 60Hz three-phase AC motors.
This manual describes the AMDP‑X/F841 series motor protector, a digital, DSP‑based device that monitors three‑phase AC motors. It details the main features, protection functions such as phase loss, short‑circuit, ground fault, overload, over‑/under‑voltage, and provides wiring diagrams and parameter configuration procedures.
The document also covers the LED display operation, keyboard functions, analog 4‑20 mA outputs, fault codes, and installation dimensions, helping users set up, operate, and maintain the protector in industrial environments. This manual is written in Chinese.
