Introduing how to setting the DLB function with the EKEPC2 -C/S EVSE Controller
EKEPC2-C/S EVSE controller DLB function setting process like bellow
1)Choose EVSE Controller model and DLB current monitoring device
Commom EKEPC2-C or EKECP2-S controller only support kWH meter as the DLB current monitoring device,if you using CT(Current Tranformer) as the DLB current monitoring device,you need choose EKEPC2-S-CT or EKEPC2-C-CT,this model has integreted a CT converter PCB inside so can read CT singal.
| EKEPC2 Controller Model | DLB current monitoring device | |
| Single Phase | Three Phase | |
| EKEPC2-C | 1Ph KWH Meter with support RS485 | 3Ph KWH Meter with support RS485 |
| EKEPC2-S | 1Ph KWH Meter with support RS485 | 3Ph KWH Meter with support RS485 |
| EKEPC2-C-CT | Current Transformer | |
| EKEPC2-S-CT | Current Transformer | |
2)Installation the DLB monitoring device
Instailation the CT/KWH meter at the incoming side of this DLB circuit,eg.in home you need installation close to Mian switch or Main KWH meter.
3)Open the DLB function in EKEPC2 EVSE controller
you can pls open the front cover ,setting the number 2 DLB function to top On position in DIM switch
4) Using RS485 communication setting DLB Max Current and register address for kWM meter
you need using USB to RS485 converter to setting the register address 96,101,102,103, for 102 the DLB maxmum current should not exceed incoming total current of DLB circuit.
Modbus communication protocol, baud rate: 9600, 8, n, 1 Address: 1-255 Default: 255 (broadcast address)
| Register address | Data description (power failure protection) | （R/W） | type of data | Defaults | Remark |
| 96 | 2# DLB current address of the meter (65535 is an invalid address) | R/W | 16-bit integer | 65535 | you need setting the DLB meter Address02,bund rate 9600,N,8,1,single phase choosing total current register address,three phase choosing three phase average current register address,meter function code 03 or 04,only DLB with Meter need setting this parameter |
| 101 | DLB maximum startup current (0.01A) | R/W | 16-bit integer | 3500 | this is the restart current when charger pause charging during the DLB function processing,3500 means 35A,the different value between startup current and DLB Maximum protection current is the charger minmum charging current,here is minmum charging current is 10A,if you setting minmum charging current 6A ,then the value is 3900 |
| 102 | DLB maximum protection current (0.01A) | R/W | 16-bit integer | 4500 | 4500 means 45A,you can change this current setting |
| 103 | Maximum current of DLB current transformer (0.01A) | R/W | 16-bit integer | 10000 | 10000 means 100A,you need setting the CTRatio,eg, 100/5 CT you need write the value 10000,if 150/5 you need write 15000 value,only DLB with CT need setting this parameter |
