Operating Instructions Chapter 6

CLV490 Bar Code Scanner

Operation

A2. Tracking mode (controlled by Increment)

• Max. 10 consecutive objects in conveyor direction simultanously in the reading field,

reading one side with internal object tracking

Conditions:

• 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 (data output)

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

event-controlled focus position switchover

• Incremental encoder connected to "IN 4" switching input

Possible reading triggers:

• One external sensor (e. g. photoelectric reflex switch)

• Command strings

Further preparations:

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.
