Original Mebay DC80DR MK3 Start Stop Diesel Generator Controller Module RS485 Monitoring

Original Mebay DC80DR MK3 Start Stop Diesel Generator Controller Module RS485 Monitoring

Overview:
This series of controllers are designed for the start, stop, parameter monitoring and fault monitoring of generator sets and have parameter setting functions.

This controller uses a dot matrix LCD screen to display the relevant parameters of the generator set, and displays the relevant fault status through the LCD screen. It can effectively implement protective parking when the generator set is not working properly.

The controller uses LCD display, built-in simplified Chinese, English and other display interfaces are optional, 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, and can be widely used in various types of generator set automation systems.

Wide Application Range

Medium silent single diesel generator control cabinet, construction machinery single engine unit, light marine auxiliary genset, off-grid medium independent power supply equipment, generator repair shops and medium power distribution engineering projects that only need standalone genset automatic start-stop + remote centralized cloud monitoring without electronic injection ECU data reading and ATS automatic mains transfer requirements.

Common Equipment Failures Solved

• Generator cannot auto start after receiving remote signal: Remote dry contact wiring loose, auto start delay 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
• No remote monitoring function reminder: DC80DR built-in RS485 port, compatible with DT1000 DTU to realize full cloud remote management
• No engine ECU data display reminder: DC80DR MK3 model has no CAN J1939 bus, select DC92DR MK3 if electronic injection ECU reading function is required
• Frequent low oil pressure / high water temperature alarm: SGPT110 pressure/temperature sensor damaged or threshold parameter misadjusted
• Old DSE5220 or DC80D MK3 panel upgrade replacement: DC80DR MK3 fully compatible with original installation and wiring, direct upgrade and replacement
