Operation
The selected reading mode depends on the number of objects that are simultanously in the
reading field of the CLV during each reading interval. This is independent of the number of
bar codes on the actual object.
Table 6-6 shows an overview of the configurations and ap-
plications.
A. CLV in stand-alone configuration
A1. Start/Stop mode
• One object in the reading field per reading interval, reading on one side
Possible reading triggers:
• One external sensor (e. g. photoelectric reflex switch)
• Two external sensors
• Command strings
• Free-running mode
Further preparations:
¾ Configuring distance configurations:
see Chapter a) Parameterizing focus position switchover, Page 6-9
¾ Configuring oscillating mirror (optional):
see Chapter c) Optional: Parameterizing oscillating mirror functions, Page 6-10
¾ Configuring no. of bar codes to be read:
see Chapter f) Parameterizing the evaluation characteristics, Page 6-23
Note The size of the reading field is determined by the distance between the start and stop sen-
sors in conveying direction (see Fig. 3-4, Page 3-8).
d) Parameterizing the reading trigger
Configuration Application See page

ing one side or more sides, master/slave arrangement with OTC 400
controller
