FAQ
Selection mainly depends on current rating and wireless needs. Current ratings correspond to CT models: 5A, 100A, 400A, 600A. For wireless (2G/4G/NB-IoT/LoRa), add AWT100 series module.
Up to MK+MTL+AWT100 modules can be connected simultaneously (daisy-chained via RJ45). Configure as needed to ensure communication efficiency.
Set the primary current value for each circuit (CH1~CH4) via the meter‘s panel in the “Signal Input” menu, or by writing to Modbus registers (addresses 14H~17H).
Configure in the “Alarm Setting” menu. Select alarm mode (e.g., overvoltage, overcurrent), target circuit, delay, hysteresis, and thresholds (high/low). Relays can be set to remote or associated with alarms.
Check: 1) RS485 A/B wiring is correct. 2) Address, baud rate, parity match host. 3) 120Ω termination resistor connected at bus end. 4) Test with only one device online to avoid address conflicts.
