1. Summary(Tóm tắt)

The power system contains rectifier modulule, battery, monitor

unit and some wiring units. The main parts of the system are modules,

it accomplishes N+1 redundant backup, hot-plug and on line repairable.

1.1 System Type Explanation

1.2 System Characterization

Main monitor unit adopts 320×240 LCD Chinese-Englishdisplaying, touching operation.

The monitor parts are modules. The control systemadopts(thông qua) distributing CPU mode, Communication adoptsRS485 mode between main monitor unit and all units includesome inspecting units and rectifier units.

Configure battery-detecting unit for detecting voltage ofevery one; the insulation inspection unit can detect bus andbranch circuit insulation states.

2.1 Main function

Detect the output current of the rectifier module and errorstate: When there is error, the system will make sound andlight alarm signal and average the load of rectifier moduleagain.

Locally or remotely control the on/off of the rectifiermodule and auto control equalize/floating charge of thebattery.

Locally or remotely set the output voltage and current limitof the module continuously(lien tục).

Monitor DC output voltage and current, the state of MCB, fuseplug state, insulation state and dropping voltage modulestate. When something is wrong, it will make sound and lightalarm.

Monitor battery voltage and charging/discharging current:When AC main terminal voltage begins to drop(khi mà ACcurrent bắt đầu giảm), if it drops to alarm upper limit(nếunó giảm xuống tới giới hạn trên), there will be sound and

light alarm; When the AC main recovers, the system controlsequalize(cân bằng) charging for the battery; If the batteryis in floating charging state too long, the system controlequalize charge for the battery every other time formaintaining it(duy trì nó). (The time is set by users and thedefault value is 720 hours.)

Support detecting batteries. It has over/under-voltage andvoltage difference(chênh lệch điện áp) alarming function forsingle battery and finds the error battery exactly.

Support insulation testing branch circuit of bus bar. Therewill be alarm if the insulating resistance of branch circuitis too low.

Adopt standard communication protocol, RS232/RS485 COM port,support 1200bps、2400bps、4800bps、9600bps baud rate, it iseasy to connected with electric autoimmunization system.Realize four functions such as remote communication, remotemeasure, remote control, and remote adjust.

Provide 6 groups of frequent open contact output of relaysfor important error information and the error content can beset according to the users’ need.

2.2 Monitor System structure

The basic configurations of the monitor system are main monitorunit, AC monitor unit, DC monitor unit, and digital value I/O unit.The optional units are battery detect unit. The above configurationcontains all of the functions of DC system. The theory of system is asfollow:

Users can touch the“Startup” button to startdischarging, touch “Stop”button to terminatedischarging. Beforestarting discharge,operator need clear thelast records ofdischarging capacity anddischarging time bypressing “Clean” button.System will automaticallystop computation on thecharging status.

Other explanationThe method of

eliminating “equalizeovertime” fault: users canmodify charging mode of the alarming bat group in the operating system,“Exit” or “Save” is ok.

The setting system can automatically inspect, if the parameter isillegal, the “system parameter fault” will be shown, because thepower’sun-M4 dose not communicate with units and rectifiers, theeliminating method: checking up the parameters of system configure,system setup and operating system, if there are errors, users canmodify the corresponding items, and then made the power’sun-M4 power onagain, users do it repeatedly until it is ok. Restore system’s originalparameters by inputting original password in the system setup, and thenmodify the setting parameters again.

System password includes system setting password, system controlling

7. Common fault processing

7.1 PM4 common fault processing

Fault name: Monitor blue screenFault phenomenon: The monitor does not have any display, does not stop

the twinkle

Reason analysis: The monitor has not inspect the data

Processing method: Disassemble the host monitor, insert the data bus

again. If supply power the display is

still exceptional, had to relate with the company to

replace this host monitor

Fault name: The monitor is fuzzy

Fault phenomenon: The monitor has the display, but displays gloomily,

not easy to distinguish

Reason analysis: The brightness adjustment of the monitor is

unreasonable

Processing method: The different model monitor adjustment display

brightness method is as follows

PM3, PM3BJ liquid crystal box monitor: In main page, press

key to increase the monitor brightness, press key to

reduce the monitor brightness, when adjust brightness need

press key which does not stop until the brightness is

appropriate;

30


PM4 touching screen monitor: Adjust the brightness must to

be on “The system setting/the brightness adjustment”

Fault name: Monitor black screen

Fault phenomenon: Monitor black screen, when pressed key the buzzer is

not loud

Reason analysis: The liquid-crystal display has not worked

Processing method: Inspect whether there is 90--320V voltage on the

power terminal of the host monitor, if

there is no voltage inspect whether the power bus

becomes less crowded, if normal

must relate with our company to replace this host

monitor

Fault name: The touching screen response is not keen

Fault phenomenon: The touching screen display is normal, but when

touches the display monitor, pressed

key function shifts or does not have the response

Reason analysis: The touching scope must be redefined

Processing method: Adjust the touching screen, the concrete step is as

follows

1. Separate the host monitor power, press the display monitor to

obtain the electricity, the monitor enters the updating

procedure again；

2. According to the monitor prompt “Please click on the left-

top corner luminescent spot”, clicks on the top left-hand

corner luminescent spot gently with tiny hard；

3. According to the monitor prompt “Please click on the right-

under corner luminescent spot, clicks on the right-under

corner luminescent spot gently with tiny hard；

31
