Manual Instruction

1. Install RS232 driver
   Please see the CD-“usb driverV3.1”
2. Install the software
   Open the CD, find the “T-937 回流焊控制系统.exe（T-937 Reflow Soldering Control System.exe）”, double-click, start to install.
3. Software Operation
   1. Viewport setting
      After open the software, you will see the ”viewport setting”, in order to get good visual effect, please set the time parameter of viewport to ”reflow target time +10S”, set the temp parameter to “target peak temp+20℃, press “confirm”
   2. Operation with PC
      Please use the communication line to connect with computer.
      Open T-937 software, press menu bar-other function-system parameter, open the setting window. Select “USB-SERIAL CH340 (COM**)”, press “confirm” and return to main interface, you will see like this in the shortcut bar, then press F2 on the reflow oven, T-937 reflow oven LCD displayer will show “connected with PC”, also you will see in the software, connect successfully.
   3. Make the wave
      1. Set the solder paste character click “Display setting area -7 paste”, the wave will display in the client drawing area. Click “display setting area – paste user”, it will show the user-defined paste character, or the the paste character from the paste database. Use the paste database from software
         Select the paste model from the shortcut bar, the paste wave will display in client drawing area.
         User define paste data
         Click “others” –“ user defined solder paste”, it will show “user defined paste window”, fill in the paste parameters you use, click “save”. This wave will display in the client draw area.
      2. Set up the wave
         open the wave from machine memory
         Click “menu” – “open recipe”, select the wave you want to use.
         Tips：this machine is with 8 waves inside, if these 8 waves can not match your solder paste, please adjust the wave in order to match with your solder paste, get good reflow effect.
         Set up wave
         Under “place control points state”, the mouse cursor will change to （click the right mouse button to switch “place/check control points state”）, then click in the client draw area, place the control point, set up new wave.
      3. Adjust the wave
         Under “check control points state”, double click the client draw area, it will show many control
         also you can use to adjust the wave in different direction, it can change the wave fastly. Tips：the paste character wave show the theoretical wave, in fact, due to the influence of various factors such as heat conduction rate, so please adjust the wave according to the actually reflow effect, in order to get perfect soldering effect.
      4. Preview the wave
         Please click “operation” – “profile preview” to check the wave which the user made if it meets request, if the temps are over the “T Limit” (in the display setting area, No.9) , this software will set these temps to 45℃ automatically.
      5. Set the wave heating time
         Please set the heating time in the shortcut bar –

2. operation tips(F1/select next wave ; F3/select last wave; F2:switch last/next 8 mins wave)

1. Set temp
2. set time（–:– is untimed model）
3. operation tips（F1/ up，F2/ down，F3/switch set temp or set time
4. current temp
5. current running time

Operation

1. Enter the software interface
   Press F1, will come to the independent operation interface
2. Select the wave
   Under the independent operation interface, press F2 to select wave, press F1 and F3 to select the wave you need, then press “return key” to independent operation interface.
3. Run the wave
   Under the independent operation interface, press F1, it will run the wave you selected.
4. Thermostatic timer function
   Under the independent operation interface, press F3, start the thermostatic timer function. Thermostatic timer function means the machine can keep thermostatic temp if you set time, once time over, the machine stop heating.
   Press F3 change “set temp”/”set time”, press F1/F2 to adjust the numerical value, the time is–:– is untimed model, means the machine is keeping thermostatic heating, not stop automatically.
