l Digit display

Voltage, current, alarm and power off information
V/A Switch button for display the output voltage and current alternately
3 digitals display, the voltage accuracyis ±0.5V (±0.1V of 48V/24V), current accuracyis ±0.2A.
View fault code by pushing V/A Switch button when alarms
Display OFF when push the V/A Switch button when the rectifier module is off.

l Indication light

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

l Display switch button

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.

l Manual 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“∧”.

l Fault Display

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.

l Communication Function

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
4	Remote regulating	Regulate output current limit threshold within 10%~100% according to commands.
