  • Page 6: Rs485 Cable Connection, Shielding, And Grounding

    RS485 Cable Connection, Shielding, and Grounding The FG terminal of the FR-DCMG must be grounded, otherwise communication will interfere and the reliability of the device will decrease. The grounding wire should be grounded nearby. The grounding wire should be no more than 15cm from the “FG” terminal to the bottom of the combiner box.

  • Page 7: Operation Interface Display

    Operation interface display Button Key Operation FR-DCMG-MMPU has four keys “ESC”, “-”, “+”, and “SET”. "ESC" key is used to return to the default interface and cancel parameter setting; “SET”key is used to enter the parameter setting mode, select the parameter to be set and complete the setting of the parameter;...

    Channel current and power generation display interface In the histogram mode, press the "+" or "-" key to enter the channel current and power generation display interface. The current value and cumulative power generation of each channel are displayed on the screen. When the "+" key is pressed first, the digital value of the current is displayed first, and when the "-"...

  • Page 10: Parameter Setting Interface

    Parameter setting interface In the histogram interface, press the "SET" key to enter the Modbus parameter setting interface. The Modbus parameter setting is as follows: • ADDR: The communication address of the Modbus slave node, the range is 1 ~ 247 (default is 247).

  • Page 11: Alarm Status Display Interface

    HV：Keep • SV：Software version number • ST：Keep • Alarm status display interface Alarm messages can be cleared remotely and manually. Manual clearing requires long-pressing the host's "ESC" key for 2 seconds, remote clearing requires writing "1" to register 0x0079 to clear. If an arc alarm occurs, it must be cleared manually or remotely. Restarting the host will still display the alarm message.

  • Page 12: Items That Can Generate Alarms Can Be Set

    system jumps out of the interface as shown below, indicating that the alarm status has been cleared; remote processing needs to write "1" to 0x0079 to clear, and the interface shown below will be displayed after clearing successfully. Items that can generate alarms can be set Voltage is too high Voltage is too low Temperature is too high...
