THE CONTROLLER

How do I use N_electronics controller?.

If you are looking for the manual you should look here .

This controller is completely managed through a computer USB connection. From the PC program you can do everything:

  1. Define 4 different soldering profiles for you oven.
  2. Adjust and test the PID settings to have the best possible temperature regulation.
  3. Configure the folder where you soldering curves will be saved.
  4. Look the real-time temperature vs time graphs during the soldering process.

Why this controller needs a computer to work?.

Honestly our firsts prototypes for this controller had a build in LCD screen and a nice set of buttons to change the configuration of the temperature profiles, this controller could function completely stand-alone from a computer. But, after a while we decided it was much cheaper and better to get rid of all this. The reason is simple, if you want to control you soldering profiles you must see the soldering curves during soldering, and this can not be done with build-in small LCD. Also changing the configuration with some buttons on the board with lots of menus is quite…exasperating.

After a while playing with a stand alone controller we saw that we were always using it connected to the PC as the configuration and monitoring was muuuuch easier with a computer, so we decided to eliminate the in-built LCD and buttons and save quite a lot of money in the final price of the board.

Anyway if you don’t have a lot of faith on Windows controlling you soldering process, don’t worry. The controller only needs the computer as an interface. If you start the soldering process and the computer stops working this is not going to affect the controller. Once the soldering program has been started from the PC the controller can work completely stand alone.

Specifications.

  • Operating systems: Windows XP, Windows Vista, Windows 7, Windows 8.
  • Temperature measuring accuracy: From 0-250ºC +/- 3ºC.
  • Type of temperature sensor: Any thermocouple type K, but you should look for one able to survive temperatures over 250ºC as our oven work at this temperatures.
  • PWM frequency: 3 Hz.

    You list the temperature measuring range as 0-250ºC +/- 1ºC. Is this the absolute limit? I would find this useful as is, but also see the need for controlling temperatures up to 1200° Celsius for some types of ovens or kilns so I thought I would inquire about the limitations.

      It is not the absolute limit, as the analog reference is fixed to 3V and we have 5mV/°C signal from the amplifier so the actual limit would be 600°C. Sorry for that, we were not thinking about someone using it for 1200°C.

    Hey,

    I recieved your controller in good working order,
    now i was wondering if I want to use the sequencer
    do I need an upgrade of the firmware of the controller?
    Greetings

      Hi Erwin,

      No problem, you can use the sequencer, the only type of phase that will not work is the PWM in the output2, the other features and types of phases will work without problems. If one day you want to change the firmware just send it back to me and I will reprogram it with the latest version.

      Best regards,
