  • Page 40: Voltage Supply

    In master/slave configurations, VISOLUX recommends a voltage supply with at least 24 V DC. The power consumption of the different VB34 models is slightly different. When several VB34 readers are connected in a master/slave configuration, the maximum power consumption per reader is 15 W. Starting the motor results in a peak demand of approx.

    VB34 test cable Adjusting the reader The VB34 reader is able to read labels at most angles, however, a strong distortion can have an unfavourable effect on reading performance. When assembling the VB34, note the following three ideal angles for the label position: Tilt angle 0°, angle of rotation 10°...
  • Page 42 Barcode reader VB34 Installation Figure 6.41 Tilt angle The angle of rotation is represented by the value S, see figure 42. Adjust the reader in such a way that the angle of rotation is at least 10°. This prevents a direct reflection of the laser beam emitted by the reader.

  • Page 43: Typical Installations

    Typical installations 6.6.1 Standard installation The VB34 reader is fitted on a ST-237 mounting angle with 105° (see figure 4), which ensures an angle of rotation (S in the following figure) of 15° to the level of the image. (Generally, the angle of rotation should lie between 10° and 20°.) This prevents a direct reflection of the laser beam emitted by the reader.

  • Page 44: Typical Hardware Configurations

    During online operation, the reader is activated by an external trigger (light barrier) when an object enters the reading zone. In the following example, the signal is created via a C-BOX 100 to the VB34 reader, which also supplies the system. *) Presence sensor connected to the external trigger input.

  • Page 45: Loops

    In this case, no external trigger is used. The C-BOX 100 is used only to supply the reader. The VB34 reader (as an Ethernet, DeviceNet or Profibus model) is connected to an external fieldbus host. It can be activated by a signal from the external host or always be active in automatic operation mode.

    RS232 master/slave for VB34 master/slave fieldbus models 6.7.4 Multiplexer The Multiplexer layout serves to integrate VB34 slave readers into a Multidrop network, which consists of different readers without a Lonworks interface . All the readers are connected via the primary interface to a Multiplexer.

  • Page 49: Local Lonworks Network

    With regard to the design of your network, always consider the following points: • from an electrical point of view, the network supports up to 31 VB34 readers with a network length of 130 m. • the maximum number of supported VB34 readers depends on how the system components are supplied.
  • Page 50 Barcode reader VB34 Installation The slave readers are connected together via the Lonworks connector plug. The network must be completed with a BTK-6000 termination network on the 9-pin socket of the last slave reader. Central light barrier The presence sensor is connected to the C-BOX 100 and is used as the sole, central trigger source in the system.
