    INTRODUCTION The purpose of your Wulftec equipment is to wrap palletized loads with stretch film or netting using various modifiable wrap parameters. Importance of the Manual This user reference guide, included with the machine, contains mechanical drawings, electrical schematics as well as a CD containing the machine programs and drive parameter settings.

  • Page 8: Safety Instructions

    SAFETY INSTRUCTIONS Read Carefully Before Operating Any Wulftec Machinery Wulftec stretch wrap machinery should be handled with the same caution and care as with any other industrial equipment. Many automatic functions may be potentially hazardous. For this reason, except for the authorized operator(s) and maintenance crew, other personnel should keep clear at all times.

  • Page 9: Inspection

    INSPECTION TRANSPORT INSPECTION Immediately upon arrival, visually inspect machine for damages caused in transport. If damage to the machine has occurred, it must be reported to the freight carrier immediately and Wulftec should be notified. As stated in the warranty, Wulftec is not responsible for damage caused in transit. If no damage is apparent, carefully remove all wrapping material, strapping, blocks, etc.
  • Page 10 GENERAL SAFETY The wrapper has been built in compliance with the presently valid technical rules and is reliable in operation. It has been submitted to a final test on the functionality of components, protections, controls and emergencies. However, dangers may still arise from this machine if it is inappropriately used by untrained personnel or if it is used for purposes it is not intended for.
  • Page 11 PERSONAL SAFETY It is mandatory to respect the following personal safety guidelines to prevent all types of injuries (minor to fatal). Use the E-Stop button if stopping machine movement (wrapper/conveyor) rapidly is necessary. Never try to stop or hold a pallet while it is in movement on the conveyor line or on a turntable. Never use or service the machine without proper safety protections (deactivated or absent).
  • Page 12 PERSONNEL The wrapper must only be operated and serviced by authorized, trained and instructed personnel. Instructed personnel consists of persons who have been informed about their work and the dangers that may possibly arise in case of inappropriate behavior and who have been trained, as far as this was necessary, and instructed about all necessary safety installations and safety measures.

  • Page 15: Installation

    INSTALLATION To install the machine is to unwrap, erect and position structures, align, level and position all conveyors according to the machine’s layout drawing specifications and install any options the equipment could have. Install all junction boxes and liquid tight wire runs under the conveyors. Make sure all sensors and quick plugs are properly connected. Hook-up necessary communication signals, required electrical power (always done by an electrician) and air supply.
  • Page 16 INSTALLATION (CONT’D) Important! Refer to mechanical layout to make sure you have the proper measurements or information regarding the machine since machine height, conveyor positioning and control panel location have already been pre-determined by Wulftec according to the specifications received. Make sure machine is placed on a level surface before and after unpacking and that machine structure is level as well once placed in position.
  • Page 17 INSTALLATION (CONT’D) 13. Plug in pneumatic components to air supply. Make sure CFM and PSI are appropriate (refer to mechanical drawings). 14. At this point, if the necessary wires for the communication signals have been pulled, plug them in the proper terminals according to the electrical schematics, prior to moving on with the start-up procedure.

The leg with the junction box and control box with the E-stop goes on the motor side facing the outside (B) Install the second leg Put the 3 bolts, locks and nuts to hold the legs.
  • Page 20 INSTALLATION OF FENCE HANDLE Refer to the mechanical drawings in order to facilitate the installation of the handle on the safety fencing. INSTALLATION OF LIGHT CURTAIN The light curtains must be installed at the end of a conveyor, away from the wrap zone and be positioned as close to the conveyor side as possible (refer to overview drawing).

  • Page 21: Glossary

    GLOSSARY Analog sensor: Supplies a proportional signal corresponding to the distance from the target to the sensor face. Autoheight: A feature characterized by a photoeye constantly monitoring the height of the carriage in relation with the height of the load being wrapped. The optical sensor detects when the carriage has reached proper height and gives the signal to the PLC to stop the carriage.
