Operating Instructions Chapter 6

CLV490 Bar Code Scanner

Operation

B2. Tracking mode (controlled by increment)

Note SICK AG can design and preconfigure more complex omni-portal systems to fulfill the

customer's reading requirements and then provide appropriately trained personnel to

install, test and put these systems into operation.

An overview of the parameterization steps for an example situation is given below (the

overview does not include all available parameterization options).

Conditions:

• Max. 20 consecutive objects in conveyor direction simultanously in the reading field.

Example: Omni-directional 3-side reading with groups of CLV490 (slaves) and OTC400

Controller (master) for object tracking

• Minimum object gap between two objects in conveyor direction: 50 mm (1.97 in)

• Size of reading field = distance between sensor for beginning/end of object and object

release point parameterized in the OTC400 (data output)

• Autofocus/focus position switchover in the CLV490 according to application:

– with OTS height information via CAN bus for reading from top

– one distance configuration (fixed focus) for e. g. reading from side and sufficient

depth of field (DOF)

• Autofocus mode "Differential background and tracking", see Table 6-6, Page 6-13

• Sensor for beginning/end of object and incremental encoder connected to the OTC400

• Master/slave arrangement using the CAN interface

Possible reading triggers:

• via OTS

Further preparations for each CLV490:

¾ Configuring reading area: see Chapter a)Parameterizing reading area, Page 6-10.

¾ Selecting focus control mode: see Chapter b) Selecting focus control mode,

Page 6-11.

¾ Configuring focus control: see Chapter c) Parameterizing focus control, Page 6-12.

¾ Configuring oscillating mirror (optional): see Chapter e) Parameterizing oscillation mirror

functions (optional), Page 6-17.

¾ Configuring no. of bar codes to be read: see Chapter h) Parameterizing the evaluation

characteristics, Page 6-36

Note To separate bar codes of the same type with identical contents, connect an incremental

encoder and activate the "Seperate codes dependent on reading angle" function. See also

Table 6-24, Page 6-36.
