Operating Instructions
3 Introduction
The reflow controller controls your reflow oven kit. To get the best soldering result, specified times and temperatures must be maintained when soldering SMD components using solder paste.
The reflow controller regulates your reflow oven in such a way that times and temperatures are maintained and the optimum soldering result is achieved.
The boards and components are heated gradually during a preheat phase in order to avoid mechanical stress in those elements.
Following the preheat phase, the temperature is raised to just below the soldering temperature. In this way, the volatile components of the solder paste can escape with no blistering.
The oven is then heated to the soldering temperature. The solder paste liquefies and the components adhere to the board. The temperature is kept stable during the soldering process in order to avoid damage through overheating.
The controller beeps to signal the end of the soldering phase.
The soldered board can now be removed from the oven.
You can adapt the solder curves to your own requirements. Up to five different curves can be stored in the reflow controller.

6 Self-test
When the controller is switched on, it runs a system test.
• Display test
The version number of the software will appear on the screen for around one second.
Please have this number ready in the event of any support queries.
• Sensor test
A temperature sensor check is done to determine whether a sensor is attached and if so, to ensure it is isolated from the mains.
If no sensor is found or the sensor is giving an error message, the display will show the status “Error” followed by “Sensor”.
If this error is displayed, please check the sensor and ensure it is attached correctly. The error message will disappear as soon as the controller finds a correctly attached sensor.
• Buzzer test
The acoustic alarm is activated for one second.
The first time the controller is switched on or following a software update, the error message ‘Learn’ will be displayed after the self-test.
This indicates that the controller has not yet learned the oven characteristics and is not ready for operation. A learn cycle must be carried out.

7 Operating modes/soldering
7.1 Appropriate oven
Please note that specific characteristics must be set for every oven type. In general, the following capacity limits apply for reflow ovens:
Europe: 220..240 V~ / 8 A, 50 Hz
USA: 110 V~ / 15 A, 60 Hz
Maximum power consumption: 1500 W
Higher oven capacity than the above is not supported and will destroy the controller.
Page 9 of 39
Reflow Controller V3 PRO
Operating Instructions
Please note that the oven must be able to build up to the temperature required for the soldering process. If the oven capacity is too low, it heats too slowly and this may expose the components to more thermal stress.
Please note the maximum temperature resistance of the sensor.
Note on using fan (convection) ovens:
Fan ovens should not be used because when the heat and fan functions are controlled simultaneously, the resulting air movement causes ‘hot spots’ in the oven, which can lead to significant temperature fluctuations.
7.2. Preparing the oven
TIP
Before you start soldering, you must prepare the oven and the temperature sensor.
• Connect the supplied sensor to the reflow controller, taking care to maintain correct
polarity.
• Run the sensor cable into the soldering area of the oven.
• Secure the sensor in such a way that the end of it is as close as possible to the
soldering material.
Attach the temperature sensor to a segment of board using a wire and place it along- side the board to be soldered. The board segment should have specifications identical to the board to be soldered.
The sensor supplied is heat-resistant up to 260 °C (500 °F).
Please ensure that your oven does not exceed the above temperature.
Please ensure also that the sensor cable does not come in contact with oven parts that may be hotter than 260 °C.
• Connect the mains plug of your reflow oven to the controller socket.
• Switch your reflow oven to the highest heat capacity.
• Switch the upper and lower heat on and slide the grill into the middle of the oven.
• Switch the oven temperature regulator to the highest setting.
• Set the oven timer to > 30 minutes. The oven should not be preheated

Reflow Controller V3 PRO
Operating Instructions
7.3 Learning the oven characteristics
Before the oven can be used for soldering, the controller has to learn its heat and temperature characteristics.
This is necessary before first use and after every software update at least.
The learned values are stored in the controller and used for all subsequent soldering processes. However, you can repeat the learn process as often as you wish.
The controller always uses the results of the most recent learn event.
The message “Error learn“ on the display indicates that the learn phase has to be run and the controller is not yet ready for soldering.
When you see this message, start the learn process by pressing START.
You can also start the learn phase at a later time, as follows:
• Connect the oven and temperature sensor according to the instructions and switch on
the controller.
• After the self-test, please wait until the oven is heated to a just below 50 °C.
• Now press OK once and the message “Setup” will appear on the display. Press OK
again and press “Down” while the message “Setup” is still present (around 2 seconds).
“Learn” will now appear in the bottom line of the display. Press OK to start the learn
process. Please wait until the learn process is fully complete and do not interrupt it. The
controller is only ready to use when the learn process is complete and the oven is at just
below 50 °C.
• The learn process requires a board to be placed in the oven and the temperature sensor positioned under or over the board in such a way that they make contact with each other.
This will ensure that the temperature sensor measures the board temperature and not the air temperature.
• Close the oven and start the learn process as described above.
During the learn process, the “Learn” status is displayed, with information on each
phase of the process.
Page 11 of 39
Reflow Controller V3 PRO
Operating Instructions
The oven is now heated to 100 °C. Once it reaches this temperature, the heat is
switched off. The controller now measures how much more the oven will heat despite
the heat being off.
A beep signals the end of the learn process and the display indicates the “Cooling”
phase.
• The oven door can now be opened.
The controller has now calculated and stored the oven’s characteristics.
When the oven has cooled to below 50 °C, it is ready for reflow soldering.
7.4 Reflow soldering
The reflow controller works by taking control of the oven. It uses one of 5 possible parameter sets for the reflow process.
In this way, you can define parameter sets for different soldering processes. Please select the required parameter set before starting the soldering process.
Chapter 9, “Setting parameters via the computer”, contains further information on how to change the active parameter set.
The number of the currently selected parameter set is shown on the display.
Ready 2 125C
The soldering process can only be started when the reflow oven has been heated to
< 50 °C. If you want to solder several boards in quick succession, the oven temperature must drop to below 50 °C between each soldering operation.
To solder the board, position it in the middle of the grill. Place the temperature sensor under or over the board in such a way that it makes contact with the board. This ensures that the sensor will calculate the board temperature and not the air temperature.
Close the oven door and check again that the temperature sensor has not slipped away from the board.
Press START to begin the automatic soldering process.

9 Setting parameters via the computer
9.1 Connecting to the computer
The reflow controller has a USB port which enables it to be connected to a PC or Notebook.
You can also update the reflow controller software via the USB port.
When you attach the USB cable, a new serial interface will be available. Further details can be found in the section on the USB driver.
You can set controller parameters using this serial interface in the same way as using the display. Other data such as status and diagnostic information can also be output and logged for quality assurance purposes.

Operating Instructions
9.2 Installing the USB driver
Depending on the operating system, it may be necessary to install driver software. The reflow controller uses a standard FTDI USB serial converter chip.
An up-to-date LINUX system does not require a driver as it will recognise the USB chip and allocate a port /dev/ttyUSB0. If you already have another USB serial converter in your system, the multiplexer will connect to port /dev/ttyUSB1 or port /dev/ttyUSB2.
Driver software may need to be installed on a Windows system. Drivers for this chip are available on www.beta-eSTORE.com/RKCV3 and on the website of the FTDI manufacturer (http://www.ftdichip.com/FTDrivers.htm). If you have a different device on your PC with an FTDI USB serial chip, the driver is already available. The most recent Windows systems include the driver in the installation.
Alternatively, you can download the driver from the manufacturer’s home page and configure it according to the installation instructions.
When the driver has been installed successfully, the operating system automatically assigns a virtual serial interface (COM port) to the USB. You can control this in the device manager and also modify the serial interface number as required. You will find the settings for your virtual port in the device manager under “Ports (COM & LPT)”.
COM port allocation
Page 25 of 39
Reflow Controller V3 PRO
Operating Instructions
Please note the following:
To make software updates easier, the USB chip uses voltage from the connected computer.
This means that the device is attached to your computer as soon as you connect the
USB cable, regardless of whether or not the reflow controller is connected to the mains.
The virtual COM port will remain in place for as long as the connection to the controller is physically available, regardless of whether or not the reflow controller is connected to the mains.
Data communication from the PC to the controller is only possible when the controller is also switched on.
If you wish to connect the reflow controller to various USB ports on your computer, the operating system must carry out a new driver installation each time and assign a new virtual COM port if necessary.
This is a feature of Windows operating systems which we cannot control. To make it less inconvenient, we recommend that you always connect the controller to the same
USB socket or alternatively, use a different operating system.
In Linux operating systems, the virtual port is always on /dev/ttyUSB0, or if you are using other devices, on the next ‘free’ ttyUSB. This is the case regardless of what USB port you are using on your computer.
9.3 Interface parameters
To communicate with the reflow controller, set the following parameters for your terminal program:
• 9600 baud
• 8 data bits
• no parity
• 1 stop bit
• no handshake.
9.4 Terminal program
You can use any terminal program to communicate with the controller.
See below for examples of suitable terminal programs that are free of charge:
Windows: Hyperterminal
Linux: Miniterm

9.7 Commands for parameter setting and calibration
The reflow controller can be set for different solder pastes, different temperature sensors and different oven types. The parameters necessary to make those settings are input via the computer interface.
Please ensure that all settings relate to the parameter set currently in use. You can store up to 5 different settings (parameter sets) in the controller. In the case of all commands, if the command has no parameters, the controller will display the value currently set.

This command checks that the oven temperature has reached a level of at least X * 0.25 °C within
15 seconds. If this is not the case (e.g., due to a defective oven or the oven door not being closed fully), the soldering process is terminated and an error message displayed.
9.8 Manual operation
The operating mode “Manual operation” can only be controlled via the PC.
In effect, this operating mode allows you full access to the controller, which means you can write your own controller programs on the PC.
You can also devise special profiles or applications, for example, “managed cooling” of sintered tools.
When the controller is in “Manual” mode, the message “Manual” will be shown in the display line, along with the current temperature.
Page 32 of 39
Reflow Controller V3 PRO
Operating Instructions
The “Pulse” phase will appear in the last line of the display. In “Manual” mode, it is not possible to use the keyboard or carry out normal soldering functions.
Manual 75F
Puls
When a heat pulse is now released via the interface, the pulse capacity is displayed simultaneously for exactly one second; so for example, a 50% pulse would be displayed as follows:
Manual 75F
Puls 50%
In “Manual” mode, you can release single heat pulses via the serial interface using the command “shot X”, where X indicates the required capacity in %.
A heat pulse always lasts for a second. You can use the parameter “Capacity” to determine for how long the heat is actually switched on during a heat impulse.
Example: shot 10 --> 10 % capacity for 1 second --> Heating is on for 100 ms and off for 900 ms shot 25 --> 25 % capacity for 1 second --> Heating is on for 250 ms and off for 750 ms
At the end of a heat pulse, the measured temperature is displayed via the interface in the format “shot, seconds, +xxx, unit”.
Example: shot, 31, +058, C bzw.
shot, 31, +136, F
A period of 31 seconds has elapsed since the controller was switched on and the temperature measured was 58 °C. Data elements are separated by a comma, which makes it easier to separate each value in the control program.
Please note that for safety reasons, the oven cannot be switched on permanently via the interface. Every heat pulse takes exactly a second. If the connection to the control computer is lost, the oven will switch off in a second at most.
The “Shot” command can only be used under the following circumstances:
• The controller is in “Manual” operating mode.
• A previous heat pulse is completed.
