Original MEBAY DC72D MK2 Replaced By DC72D MK3 Genset Engine Control Module Panel AMF Automatic Switching ATS

Original MEBAY DC72D MK2 Replaced by DC72D MK3 Genset Engine Control Module Panel AMF Automatic Switching ATS

Overview：
    This series controller is specialized for Diesel / Gasoline / Gas Genset Start, Stop, Parameters monitoring, faults-checking as well as data setting.
4.3inch colorful LCD screen display with brand new UI design is adapted in this controller that the relative failures can be displayed directly. All the parameters can be displayed by simulated indicators and words. Besides, LCD screen can display various faults in the same time that the genset will be stopped once it can’t work smoothly.
    There are Chinese/English interface options, more language can be set according to user’s request. All the parameters can be configured through the front face buttons or use programmable interface by RS485 or USB or ETHERNET interface to adjust via PC. It can be widely applied for all kinds of auto control system of gensets.

Wide Application Range

Medium silent single electronic injection diesel generator control cabinet, commercial building backup AMF genset, small data center standby power, light marine auxiliary genset, generator repair shops and medium power distribution engineering projects requiring ATS automatic switching + ECU data reading without remote centralized cloud monitoring requirements.

Common Equipment Failures Solved

• Generator cannot auto start after mains power loss: Mains voltage sampling wiring loose, AMF delay start parameter misconfigured
• Laptop cannot connect controller for parameter modification: Use SG72A USB communication adapter, install official Mebay configuration software
• Onboard relay burned when driving glow plug: Onboard contact capacity limited to 5A, install external Hongfa HAT700BI 70A heavy relay for current amplification
• Need mobile APP remote cloud monitoring: DC72D MK2 without RS485 port, upgrade to DC72DR MK2 model with isolated RS485 Modbus communication
• No remote data upload reminder: DC72D MK2 lacks RS485 port, DT1000 cloud DTU is not compatible
• Frequent low oil pressure / high water temperature alarm: SGPT110 pressure sensor damaged or threshold parameter misadjustment
• Old DSE6120 MKII base panel damaged and need replacement: DC72D MK2 same mounting size and terminal definition, direct swap without cabinet wiring modification
