• Page 28: Ultrasonic Power/Amplitude

  Ultrasonic power/amplitude .02.02 The ultrasonic generator of the 8311 can be operated with amplitude control or with power control. The switch over takes place when inputting the setpoint value. An ultrasonic power of between 5 W and 400 W can be entered by pressing the ultrasonic power touch field.

• Page 29: Welding Force

  Sealing Welding force .02.03 Other important welding parameters are the roller force for force welding or the roller gap for gap welding. Your parameters are alternatively entered under the ultrasound parameters. During force welding, the welding force is measured by a load cell on the Sonotrode and adjusted via the lifting mechanism of the anvil wheel.

• Page 30: Roller Gap

  The rollers move to a fixed position for gap welding. Since the Sonotrode is spring-loaded through the load cell on the 8311, this position can take on positive and negative values. A negative position defines a point below the zero force position of the Sonotrode and thus effects the resulting welding force depending on the material thickness.

• Page 31: Feed Roller Speed

  Sealing Feed roller speed .02.05 The feed roller speed for the bottom and top feed rollers can be entered together by pressing the feed roller speed touch field on the manual welding screen. A new input screen will open for this purpose. The feed roller speed can also be changed directly with the keys.

• Page 32
  Sealing Stop inhibitor The stop inhibitor, which can take on positive and negative values, defines the switch-off behaviour. If the stop inhibitor is positive, the ultrasound is switched off and the rollers con- tinue to run for the set time. With a negative value, the rollers stop im-mediately and the ultrasound then remains switched on for the set time.

• Page 33: Cutting Force (8311 — Dual Cut&Seal Model)

  Cutting force (8311 – DUAL Cut&Seal model) .02.06 In the 8311 versions with DUAL Cut&Seal, the cutting wheel force of the cutting wheel is determined with a stepping motor by means of a torsion spring drive. It is determined with an input/calibration function and stored in the control.

• Page 34
  Dual Cut&Seal = 1 setting, when the cutting wheel is then to extend with the rollers closed. The control of the 8311 checks this movement and can detect the loss of steps. In this case, the cutting wheel is deactivated and moved to the switch-off position. A yellow error LED is switched on in the display.

• Page 35: Opening / Closing The Feed Rollers

  Sealing Opening / closing the feed rollers .02.07 The feed rollers can be opened and closed with this key. If the material between the closing rollers is thicker than 8 mm, a safety shutdown is activated that immediately opens the rollers again. The purpose of this safety shutdown is to prevent the operator’s hand becoming trapped.

• Page 36: Basting

  Sealing Basting The upright rollers are closed and the ultrasound is switched on briefly during the basting process. This creates a welding point that fixes the material. If you press the baste touch field in stop mode, a new screen is opened in which the basting parameters can be defined.

• Page 37: Selecting Sealing Parameters And Program Numbers

  Sealing Selecting sealing parameters and program numbers The sealing parameters are saved in the machine in 50 data sets P1..P50. P1..P6 can be selected directly with the corresponding keys. The other data sets (P7..P50) can be selected individually with the program number selection function.

• Page 38
  Sealing Note: Programs with only one section can be converted. Programs consisting of multiple linked sections cannot be converted. They must first be deleted with the program editor except for one section and only then can they be converted. Program consists of multiple sections and can therefore not be converted. This prevents programs from being inadvertently fragmented and therefore rendered unusable.

• Page 39: Manual Sealing

  Sealing Manual sealing All relevant parameters for the sealing process can be entered or altered directly in the manual sealing mode, see chapter 10.02 Description of the function keys. The manual sealing mode is selected with the program number selection function, see chapter 10.04 Selecting sealing parameters and program numbers.

  Sealing All other functions work as with manual welding and can be read there. As already explained in the clear view of dynamic welding, the ultrasonic parameters and the speed are calculated and connected from the pedal position during welding operations. The other parameters remain at the set values.

• Page 45: Programmed Sealing

  Sealing Programmed sealing Programs can be created with up to 12 sections by linking multiple data sets P1..P50 into one unit. It is possible to switch to the next linked data set (section) via a welding distance (length specification), via programmable inputs (switches), via a change in material thickness or by the operator pressing the pedal.

  Input Initialization of the lifting drive (roller init) With this function, the machine automatically determines the relevant positions of the upper trans- port roller and the cutting wheel (if installed). To do this, the upper transport roller traverses the en- tire travel path of the lifting drive several times in order to determine the position and the force de- flection of the sonotrode depending on the installed upper transport roller.
• Page 70
  Input Then the load cell is adjusted. The force display changes from 999N to 0N. The upper transport roller slowly lowers down to the sonotrode. After a short touch, it moves back up again. This only determined the approximate position. The upper roller then moves directly over the sonotrode and begins to measure the load cell force positions, which are saved in an internal table.
• Page 71
  Input Machines with DUAL Cut & Seal equipment then determine the cutting wheel positions for cutting forces up to 150N. For this purpose, the now relative sonotrode position is first determined. The up- per roller moves with the cutting wheel in the upper switch-off position directly over the sonotrode (position with zero Newtons).

• Page 92: Software Update

  Adjustment Software update The software of the PFAFF 8303i tape sealing machine can be updated with an SD card. If an SD card with a software update is inserted in the SD card reader (next to the main switch) be- fore turning on the machine, a special program (boot loader) is activated that performs the software update.

• Page 93
  Adjustment Should a software update be essential for whatever reason, tap on the touch panel when switching on the machine. The boot loader then appears with the same software version. If the software update on the SD card is incomplete or faulty, the update process is cancelled without changing the previously programmed software.

• Page 94: Software Update Of The Touch Panel

  Adjustment Software update of the touch panel .06.01 An update of the touch panel may potentially be required when updating the control software. A folder DWIN.SET containing update information for the touch panel can be found on the SD card with the new software. Loosen the two Allen screws on the control panel when the machine is switched off.

• Page 95
  Adjustment Put the control panel back loosely in place and switch on the machine The control panel initially displays a blue screen for a few seconds. Then all screen templates are displayed briefly in quick succession. The start screen then remains on the display. Switch off the machine again, remove the SD card from the control panel and mount the control panel on the housing using the two Allen screws.

• Page 96: Resetting To Factory Setting

  Adjustment Resetting to factory setting The sealing parameter sets, settings and parameters for the 8303i are stored in a special battery-buffered module. The data is therefore retained when the machine is switched off. Sometimes it may be useful to reset this data back to the factory setting. A simple example is, for example, the function to protect the sealing parameters with a PIN.
