8、 module has been added diode against reverse pour at output terminal.l LED digital screen, digital calibrate, stable current ,fault alarml Output overvoltage protection To prevent the disastrous accident caused by outputting overvoltage to electric consumers, there is overvoltage protection circuit

9、in the module. After output overvoltage occurs, the module locks up automatically, the relative module fault indication light is on, the faulty module quits work automatically and doesnt affect the normal operation of the entire system. The overvoltage protection point is set when ex-factory, 182V5V

10、 is set for rated output 110V machine type.l Output current limiting protect The output current cannot increase infinitely. The maximum value of the output current of each module is limited to the rated output current 105%, in this range, the output current value of the module is continuously adjust

Switching button for display shows the output voltage and current switching. There are 3 digitals can be displayed, the

27、 accuracy of voltage is 0.5V, the accuracy of current is 0.2A. When the module alarms, the fault code can be displayed by pushing the switching button. When the module shut down, the shut down code can be displayed by pushing the switching button .4.2 Indication lightThere are three indication light

If the LED are displaying the output voltage, then you push the button, there will be display output current, if you push the button again, then it

30、will also display the output voltage. 4.4 Manual adjusting voltage buttonTwo buttons embedded in the panel are used to adjust the output voltage in the manual state. The output voltage will at the lower of 1V，when the left button is pushed; also the output voltage will arise 0.5V when you push the r

31、ight button. You must pay attention to that this button is working only in manual state.4.5 Dial switchingDial switching are used to select the control module and mailing address. Definition is shown in Figure 4-2Figure 4-24.5.1 Control options codeThe dial switching of the farest left is dial-contr

32、ol options, selecting the automatic control or manual control. Control methods for allocation allocated under manual control, as shown in Figure 4-2. In automatic control mode, the modules output voltage limiting, switching planes are monitored by module control，artificial can not intervene it . If

33、modules for rechargeable batteries to switch on the bus, the general approach should be set up for control. In manual control mode, the output voltage can be adjusted by the manually button. Module output voltage limiter point and switch control module from machine control, etc. However, the operati

34、ng parameters can be reported to the Control Module.If connected to the control bus module, the module will need a single output voltage stability. At this time should be set up for manual module state, the module output voltage surge by manual adjustment buttons, limiting points are all relaxed, ab

35、out 105%.Note:Surge button manual recharging module will reach a maximum output voltage 175V. Do not adjust the normal system in the random button. Since different users have different choices and the number of battery, for the sake of safety, Charging module output in the whole factory has been set

36、 at the Floating 117V voltage values.4.5.2 Broadcast address identification code The left side of Switching dial-second is broadcast address identification code allocated，used to identify the broadcast data packets. Appropriated for the top, a module of Group 1, the broadcast data packet with 255 of

37、 253; appropriated the bottom, a module of the second group, the broadcast data packet with 254 and 255.4.5.3 Address setting dial Four of dial switching with the right allocation of broadcast address identification code addresses communications module installed together constitute dial, The mailing

38、 address for the module. Module installed in the mailing address in binary, every allocation of representatives allocated upward binary code 0 appropriated to represent binary 1. One addresses the right to set up most of dial-lowest, the most left one of the highest places. TH110D40ZZ-3-AHF charging

39、 module addresses set up for dial-five. Therefore module addresses the range of 031, that is the control module with a serial port to connect the largest number is 32. Module addresses is the only identification signals that charging control module identify others. the same system can not be install

40、ed at the same module. To the same modules, control modules to be installed mailing address, which should be the same with communication modules. Control module installed in the module addresses a number of the metric system, 4-2 with the conversion table.table 4-2Binary00000000010001000011001000010

It can send the output voltage and

44、 current, the module protection and alarm information to a host computer, accepting and implementing the control orders issued by the host computer. Note：When the charging module is in automatic model, there will not be any communication in 4 minutesThe output voltage can be adjusted to the voltage of 117V automatically. Limiting point can be open
