The AMDG-X/F42□ series motor protection is a digital setting, digital display of three-phase AC motor protection, with undervoltage, short circuit, grounding, stalling, overload, unbalanced current, underload and other protection functions.
The XWAM AMDG‑X/F42 series motor protector provides digital DSP‑based protection for three‑phase AC motors up to 1140 V, 50/60 Hz. It displays motor current, voltage and fault codes on a 5‑digit LED display and offers RS‑485/MODBUS communication, 4‑20 mA analog outputs, and a full set of protection functions such as phase loss, short‑circuit, ground fault, stall, overload and imbalance.
The manual explains how to set protection parameters, use the keypad, reset the device, connect the RS‑485 network, and wire the unit to the motor and current transformers. It also lists technical specifications, fault codes, and provides wiring diagrams for installation. This manual is written in Chinese.

Press the R key; this resets the microcontroller and stops the motor.
The device includes RS‑485 and MODBUS interfaces for network communication.
Up to 32 protectors can be placed on the same RS‑485 segment.
Use the keypad: select a parameter number with the * key, change its value with the full‑key, and save with the J key.
