Original  MEBAY ATS520IR Diesel Generator Controller Dual Power Switch ATS Control Module

Overview

This series of controllers is a dual-power switching controller with programmable functions, automatic measurement and control, and LCD display dual power intelligent switching module.

This controller uses a 3.5-inch 240*128 large-screen high-resolution LCD display and a brand-new original UI design. The controller has built-in display interfaces such as simplified Chinese and English, and the language interface can be customized according to customer requirements. All parameters of the controller can be adjusted through the controller panel buttons, or adjusted and monitored using a PC through the USB port or RS485 interface. It can be widely used in various types of power systems.

Wide Application Range

Data center precision dual-power distribution cabinet, hospital medical uninterrupted power supply system, high-end commercial building backup power ATS cabinet, industrial factory multi-generator standby power station, key engineering emergency power distribution project, marine auxiliary dual-power system, off-grid industrial multi-unit power supply base, generator factory high-end complete machine supporting assembly, renovation and replacement of imported high-end ATS integrated panels such as DeepSea and Smartgen.

Common Equipment Failures Solved

  • LCD no display after power on: Check DC battery voltage within 8~36V working range, confirm positive and negative wiring correct
  • No power data display: Check CT transformer wiring sequence and short circuit state, recalibrate CT ratio parameters via USB
  • Frequent ATS false switching: Adjust mains/genset transfer delay time to filter instantaneous grid voltage fluctuation
  • Dual genset cycle function invalid: Confirm cycle mode is enabled, recalibrate master-slave parameter settings
  • PC cannot remote connect via RS485: Check A/B wiring sequence, baud rate and Modbus address consistency
  • Overcurrent protection false trip: Adjust overload inverse time delay threshold according to actual load
  • Need engine mechanical data monitoring: Match GM50HR/DC42D genset controller, ATS520IR only responsible for dual-power switching and electrical monitoring
  • Old high-end ATS panel upgrade: 186×142mm universal cutout, direct replacement for DSE6120/HAT600 without cabinet modification
