CLV490 Bar Code Scanner

Operation

B. CLV490 integrated in OTS400 Omni Tracking System

(mechanical construction called "reading gate")

B1. Start/stop mode

Conditions:

• One object in the reading field per reading interval

Example: Omni-directional 2-side reading with CLVs (slaves) und OTC400 Controller

(master)

• Minimum object distance > size of reading field

(size of reading field = distance between sensor for start and stop of reading trigger)

• 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 "Minimum distance" or "Differential background",

see Table 6-6, Page 6-13

• Two reading sensors connected to OTC400 (start and stop)

• Height detection photo reflex switches connected to OTC400 (optional)

• Master/slave arrangement using the CAN interface

Possible reading triggers in the CLV490:

• OTS trigger

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.
