  • Page 34 CHAPTER 4: OPERATION The motor for the bar feeder is equipped with a built-in absolute encoder that continuously controls the position of the pusher. When the bar feeder is switched off or there is a power failure, this position is kept in the memory by the amplifier.
  • Page 35 CHAPTER 4: OPERATION The ergonomic and user-friendly remote control with a clear built-in display facilitates the handling of the bar feeder. Depending on the sequence under way, the bar feeder gives access only to those functions which are available, thus avoiding any incorrect handling, and reducing the access time to the necessary functions.
  • Page 36 CHAPTER 4: OPERATION The liquid crystal display provides the operator with all the necessary data, both for handling the bar feeder and for maintenance. The upper portion of the display has eleven lines and is reserved for the reading of text. Error messages are usually displayed with their diagnostics.
  • Page 37 CHAPTER 4: OPERATION These keys are located right below the display. The functions attributed to them are indicated on the display by icons. As the operator advances in the handling, the functions of the keys are automatically reattributed. The risk of error in handling is therefore virtually reduced given that the proposed functions always correspond to the circumstance and availability of the bar feeder.
  • Page 38 CHAPTER 4: OPERATION To facilitate these tasks, the MOVE S2 can be equipped with a retraction system, which allows the operator to move the bar feeder. The rigidity of the system guarantees a perfect alignment when the bar feeder is in working position. A safety switch impedes any handling as long as the bar feeder is not in operational position.
  • Page 39 CHAPTER 4: OPERATION Please read the safety instructions provided at the beginning of this manual before handling the following devices.
