CLV63x Bar Code Scanner

Product description

4.6.2 Object trigger control

In order to start an object-related reading process, the bar code scanner requires an appro-

priate external signal (trigger source) for reporting an object in the reading area. The start

signal is emitted via an external reading pulse sensor (e. g. photoelectric reflex switch) as

standard. As soon as an object has passed the reading pulse sensor, a time window opens

in the bar code scanner (“reading gate“) for the reading process.

Alternatively, a command activates the reading process via a data interface or the CAN-SEN-

SOR network. In Automatic Cycle mode, the actual bar code scanner generates the reading

gate internally with an adjustable mark-space ratio.

The reading pulse can be ended in a number of ways: With external triggering by the reading

pulse source or a command, internally by a timer or an evaluation condition to be met.

4.6.3 Oscillating mirror control

You can manipulate the position of the scanning line for the line scanner with oscillating mir-

ror (CLV63x-6000/CLV63x-6120) by configuring the oscillating mirror.

In addition to parking (fixed scanning line position which can be adjusted) or continuous

oscillation independent of the reading pulse, controlled operation of the oscillating mirror

also enables optimised operation sequences related to the reading pulse:

• n-fold oscillation around an adjustable start position within the reading pulse

• One-shot: one-time deflection (forward and return) per reading pulse from an adjusta-

ble start position

In every oscillation mode, the amplitude can be adjusted separately for each of the two de-

flection directions. The deflection speed ratio of one deflection direction to the other can be

adjusted within the selected periodic time for the entire oscillation sequence.
