Fonrich New Energy Technology Co., Ltd. Ⅰ, Important Safety Instructions Please read this user manual carefully before product installation. Fonrich reserves the right to refuse warranty claims for equipment damage if the user fails to install the equipment according to the instructions in this manual.
Ⅱ, Product Brief FR-DCMG is mainly used in the PV combiner box in PV power plants, to monitor the working status of every PV string and send the status data to the monitor center of the PV power plant through field bus or industrial wireless. Also a new function is detect arc fault in PV string or DC bus-bar.

FR-DCMG DC System Monitor User Manual Fonrich New Energy Technology Co., Ltd. Ⅴ, Local Operation Instruction of buttons operation and display interface FR-DCMG has four key buttons:“ESC”、“-”、“+”、“SET”. The key “ESC” is used to return to the default interface or cancel the setting of parameters. The key “SET” is used to enter the parameter setting interface, chose the parameter that to be configured, or confirm the setting.
“*”: The selecting cursor that can be moved through pressing “+” and “-”keys. FWB NODE:Actually, it is a wireless client mode. FWB means Field Wireless Bus, which is robust filed wireless communication protocol designed by Fonrich. In this mode, the modbus interface is also active.
FR-DCMG DC System Monitor User Manual Fonrich New Energy Technology Co., Ltd. default interface of MODBUS mode, it will be shown like below: The histogram shows the current value of every channel, the current value ranges from -2A to 10A. For the hall sensors are four channel sensors, so in the histogram every four channels will be indicated from another four channels which means that from left to right is channels 1-4, channels 5-8, channels 9-12 and so on.
PARITY: The parity of MODBUS communication, the selectable parity none parity(NONE), odd parity(ODD), even parity(EVEN)(default none parity). ADDRESS: The address of the MODBUS slave device, ranges from 1 to 247(default 1). Digital displaying interface When the key “+” or “-” is pressed in the histogram interface, the digital display interface will come up to show the current values and generated energy values.
FR-DCMG DC System Monitor User Manual Fonrich New Energy Technology Co., Ltd. FWB NODE mode Select FWB NODE mode in the mode selecting interface, if the previous mode is not FWB NODE mode, the device will reboot after pressing the key “SET”, and the device will enter FWB NODE mode.
P/T will twinkle to indicate that the communication is normal. Wireless node connecting status interface The wireless node connecting status interface will come up after the interface of LOGO, wireless node connecting status interface is the default interface of FWB GATEWAY mode, it will be shown as below: The number 1 on the left side of the top line means the online number of wireless node, the address is composed by the numbers in the left column except the top “1”...
FR-DCMG DC System Monitor User Manual Fonrich New Energy Technology Co., Ltd. Among which: NODE QTY:the supported number of the wireless node by this gateway, default 30 ranges from 1 to 216. Generally, please keep this number as less as possible, because the communication cycle will become longer as this number growing.
Then the picture will change to histogram picture. Shunt Tripping Setup Interface At default picture, press key “ESC” and “+”in same time, will change to “Shunt Tripping” set interface, shows as below: Among which: “TIME”: Set the shunt trip drive hold time, the shunt trip drive signal will be enable when alarm event occurs, and hold on set time, then disable shunt trip drive signal.
FR-DCMG DC System Monitor User Manual Fonrich New Energy Technology Co., Ltd. Ⅵ, Definition of the Modbus Protocol Configuration of the modbus Modbus communication mode:RTU mode Address of the slave device:range from 1 to 247 (default 1) Baud rate:(bps) 2400、4800、9600(default)、19200、38400 Parity of the byte:odd parity、even parity、none parity(default)
