Rev. 3.10 Manual Mistral 260 2020 There are two different modes for this function. The mode can be changed under Settings / System settings. (See Machine settings and info) A. The button shows Sensor(s) OFF or Sensor(s) ON By default, the button shows the text Sensor(s) OFF. Pressing the button changes the text to Sensor(s) ON and colours it red. The value fields are reset and the sensors are activated. In this mode the sensor(s) keep track of the highest temperature measured even if the temperature is decreasing after the soldering cycle. The time fields show the time the sensor has measured the melting point temperature. To clear both fields you have to turn off the oven or press the Sensor(s) OFF button. Pressing once more switches to Sensor(s) ON and all values are cleared. B. If the button shows Clear melt timers The sensor continuously shows the actual value measured if this mode is selected. The time field shows the last value it has measured. This is the period of time that the sensor was above the melting point temperature. To clear the timer field you have to press the Clear melt timers button. After this action you can use the sensor for a new solder cycle. Belt speed: This is the speed of the belt as set in the Recipe editor. The belt speed can be adjusted by cm/min with the + and – buttons or in the Recipe editor. If a value has to be changed the user should press the value that should be changed. This will display the Recipe editor. This screen will be discussed in the chapter Recipe editor. Invisible button: There is an invisible button between the Sensor and Recipes buttons. Pressing this button changes the screen to Max. brightness mode. This option is set in the Display & Sound screen. Please refer to Display & Sound for more information. Stop belt: With this button the belt can be stopped at any time during the process.

Rev. 3.10 Manual Mistral 260 2020 12.0 Motor setup. This screen depends on the motor type selected. Normally the right motor type is set at the factory. But it may be necessary to select the right motor type if a motor needs to be replaced. The setup screen for a machine with stepper motor is shown below. 12.1 Stepper motor functions explained Save: Save all changes. Cancel: Close the screen and lose all changes. 12.2 Stepper motor fields explained Motor type: This toggles between an analogue and a stepper motor. Selecting the wrong type of motor results in it not working – the motor does not respond to commands. This should therefore only be changed if either your reseller or the manufacturer instructs you to do so. Belt Direction: This function may never be needed, but there are situations in which it can be useful to change the motor direction. It can be switched between << or >>. The default value is 1. Speed adjust: In normal circumstances this field is never changed because the machine was calibrated before it left the factory. However, when a motor and/or spindle is changed it may be necessary to change the calibration using this field. The number is used by the controller to calculate the number of steps/min to achieve the speed requested. ...

Rev. 3.10 Manual Mistral 260 2020 Below you see the setup screen for a machine with analogue motor. This motor is more complex to calibrate. If one or two speed value(s) need to be calibrated this can be done in the screen/option below. If the whole machine needs to be calibrated it is better to use the application on the USB stick. This makes easier to calibrate multiple values. 12.3 Analogue motor functions explained Save: Save all changes. Cancel: Close the screen and lose all changes. 12.4 Analogue motor fields explained Motor type: This toggles between an analogue and a stepping motor. Selecting the wrong type of motor results in it not working – the motor does not respond to commands. This should therefore only be changed if either your reseller or the manufacturer instructs you to do so. Belt Direction: This function may never be needed, but there are situations in which it can be useful to change the motor direction. It can be switched between “<<” or “>>”. The default value is “>>”. Crystal type: This only applies to older machines. In the past a crystal was used as the time base for the controller. Later, an internal time base for the controller was used. This should only be changed if you are instructed to do so. Speed select: the speed to be calibrated should be selected here. Click the field to change the value. Factor: This value appears before and after Current factor. This is used to change the Current factor field. Changing it by just a few points changes the speed. The Current factor should be changed in ...

Rev. 3.10 Manual Mistral 260 2020 15.0 Controlling oven by serial communication. It is possible to control the oven with commands sent by serial communication. On the USB memory stick which was delivered with your oven, you will find instructions on how to install the application. The RS232 application has its own manual which will be installed together with the application. This manual shows the syntax of the commands used to control the oven. These commands can be used to write an application. Normally, a USB to RS232 chip is used for serial communication. This USB port is visual on the I/O panel on the left side of the machine. On new machines the I/O card is equipped with a legacy RS232 port as well. To use this, follow the instructions in the RS232 manual which is downloaded with the RS232 program. 16.0 Specifications The MISTRAL 260 reflow oven has been developed for lead free reflow soldering of SMT boards, hybrid boards or curing adhesives. Transport system The boards are transported through the oven on a conveyor belt (spring wires or mesh belt) made from high‐grade stainless‐steel. The conveyor belt speed can be varied between 2 and 60 cm/min (+/‐ 0.78 to 23.62 inch/min). Resolution goes in steps of 1 cm (+/‐ 0.39 inch). For analogue motors the minimum speed is 4 cm/min. (+/‐ 1.56 inch/min). The maximum permissible hight of the product is 25mm (+/‐ 1 inch) Heating system Heating is provided by forced air convection. This reduces shadow effects and results in no colour sensitivity, no hot spots and no cold solder joints. The heating system is suitable for lead‐free soldering. Cooling system Bottom cooling fans in the offload section ensure circuits cool down below melt point before leaving the transport belt. However, the product might be hot enough to cause burning. Protective equipment should be used to avoid burning. Control All functions are controlled by a touch screen display which is easy to programme with a user‐friendly interface. This control is also equipped with a USB 2.0 master port for data output to a storage device such as a USB stick or hard disk. The second USB 2.0 (slave) port is used for control by external devices, for example a PLC. The Ethernet port is not used. Exhaust ...
