System features: 1, battery management: According to float conversion parameters set by the user, the battery automatically float management, the limiting charge management, temperature compensation, battery nuclear capacity test; battery test is divided into nuclear capacity test manually and automatically test, the use of automatic test battery online activation. 2 battery overcharge protection according to user-set automatic overcharge protection, complete battery charge protection; the manual equalize protection and automatic charge at different times, you need to set the exception, are fully automatic float switch, the system serious failure automatic float switch. 3 Alarm: feed the branch open space trip alarm detected by EGU01 switch module; fuse off the battery, charger output fuse broken insulation relay alarm detected by the # EGU01 switch module; fall alarm bus insulation support Road, insulation falling alarm JYM-2 or EDU01, EGU01 insulated from the machine detection; the the distribution monitor (EAU01 EDU01) switch sampling box (EGU01), rectifier module, battery tester, insulation monitor, DC / DC module DC / AC module communication interrupt alarm, detection via CAN or RS485 communication; exchange undervoltage, phase, power failure, abnormal AC open space trip, AC lightning alarm by EAU01 detection; bus, the battery voltage over-voltage alarm, float overvoltage alarm through the the EDU01 detection; battery charging current alarm, battery pack temperature anomalies alarm, battery charging flow through the the EDU01 detection temperature EGU01 detection can also be through EBU01 detected; battery cell over-voltage alarm, detected by EBU01; rectifier module, inverter module, DC / DC module protection, fault alarm, insulation monitor, battery tester equipment failure alarm, detection via CAN or RS485 communication; background communication: with background monitoring RS232/RS485 communication . The communication protocol is MODBUS of CDT91 agreement, the user site as needed to select the desired protocol, communication protocol point table by U disk between the different monitoring module export, import, copy; the IEC61850 protocol EMU10 software version in V2. 0 or more support; 5, to upgrade and import and export data, U disk can be upgraded application can also import and export configuration files, U disk can be inserted the EMU10 \ USB port;, GPS hard on the access IRIG-B code signals (RS485) GPS hardware connected to IN2 and DGND infrared control of LCD backlight time IRIG-B code signals (RS485) to access infrared alarm device sensing staff to enter, without operator PSD and open the DC panel touch EMU10 can be achieved the EMU10 automatically turn on the backlight must be compatible with the use of infrared alarm device, the specific wiring shown in Figure 3-121; 8, the battery curve shows the current real-time battery charge and discharge curve and the curve of history, the vertical axis shows battery voltage, battery Current, and the horizontal axis shows the time, click on the map of a point to the point on the voltage, current, and time information is displayed. Button to start and stop a real-time charging and discharging curve recorder, real-time recording in the last 20 days of the positive and negative bus stop automatically recorded into the historical curve, the original historical curve record is cleared 9 Insulation curve, can be displayed resistance to ground. recorded, and the vertical axis shows the positive and negative bus line to ground resistance, the horizontal axis shows time, click on the image of a point to the points on the positive and negative bus line to ground resistance and time information is displayed. Taken within 15 minutes of the minimum value of resistance as a point of the curve is recorded every 15 minutes or so.
