Three lights on the front panel, the functions are as follows table 3-12
Table 3-12
Define | Normal | Abnormal | Reasons |
Power light (green) | on | off | No input voltage or damage may lead to internal auxiliary power supply does not work |
Over temperature light (red) | off | on | Overheating inside |
Fault light (red) | off | on | internal fault such abnormal input, over/under voltage/current |
The Display Switch button is used to switch what LED displays. If output voltage info on the LED screen, get the output current info by pushing the switch button. When push again, get output voltage back.
lManual adjusting voltage button
Two buttons embedded in the panel are used to adjust the output voltage in the manual mode. The output voltage will get down 1V (0.2V of 48V/24V models) when push left button“∨”. And the output voltage will rise 0.50V (0.1V of 48V models) when push the right button“∧”.
The alarm information in fault code is displayed in the LED screen. The fault code
definition is as table 3-14. Press the V/A Switch and get the voltage info back in the screen.
Table 3-14 fault code definition
fault code | E01 | E02 | E03 | E04 | E05 | E06 |
Definition | Output Under voltage | Output over voltage | Output Overflow protection | Output over voltage protection | Over temperature protection | AAbnormal Ac input |
Communicate with superior end via RS485. Transfer the output voltage, current,
protection and alarm information to superior end and execute the superior commands.
Table 3-15 Communication function
No. | Item | Index | PS |
1 | Remote signaling | Transfer the faults info such as AC input, DC output over/under voltage, over temperature to monitor unit | ~ |
2 | Remote measuring | Measure charging module output voltage, current and display in the screen. Same time transfer to superior monitor unit | ~ |
3 | Remote control | Control the switch on/off of the charging module and equalizing/float charge convert according the command from monitor | With Manual control function, which disable the monitor function |
4 | Remote regulating | Regulate the output voltage according to commands | |
Regulate output current limit threshold within 10%~100% according to commands. |
