Optical reading head

PCV80-F200-R4-V19

3

Mounting and commissioning

Mount the reading head such that its optical surface captures the optimal read distance to the code band (see Technical Data). The stability of

the mounting and the guidance of the vehicle must be provided such that the depth of field of the reading head is not closed during operation.

All reading heads can be optimally customized by parameterization for specific requirements. The parameterization of reading heads with a bi-

directional interface (all except SSI-interface) can take place via the interface itself (internal parameterization) or via an optical parameterization

code (external parameterization). The reading heads with SSI interface only have the possibility of external parameterization via optical param-

eterization codes.

Displays and Controls

The reading head allows visual function check and fast diagnosis with 7 indicator LEDs. The reading head has 2 buttons on the reverse of the

device to activate the alignment aid and parameterization mode.

External parameterization

For external parameterization you require the parameterization code as Data Matrix with the desired reading head parameters. Data Matrix code

cards for step-by-step external parameterization are printed in the reading heads operating instructions.

Parameterization is only possible within 10 minutes of switching on the reading head. If a button is pressed after 10 minutes subsequent to switch-

ing on, there is visual signaling via the LEDs (LED1, yellow/LED2, red/LED3, yellow/LED4, yellow/LED5, yellow flash for 2 seconds)

• The switchover from normal operation to parameterization mode is via button 2 on the reverse of the reading head. Button 2 must be pressed

for more than 2 seconds. LED3 now flashes.

Note: Parameterization mode automatically ends after 1 minute of inactivity. The reading head returns to normal operation and works with

unchanged settings.

• Place the parameterization code in the view of the camera module. After recognition of the parameterization code, the green LED2 lights up

for 1s. In the event of an invalid parameterization code, the red LED2 lights up for 2 s.

• A short press on button 2 ends the parameterization mode and the changed parameters are not stored volatile in the reading head.

Alignment aid for the Y and Z coordinates

The activation of the alignment aid is only possible within 10 minutes of switching on the reading head. The switchover from normal operation to

“alignment aid operating mode is via button 1 on the reverse of the reading head.

• Press the button 1 for longer than 2 s. LED2 flashes green for a recognized code band. LED2 flashes red for an unrecognized code band.

•Z coordinate: If the distance of the camera to the code band too small, the yellow LED5 lights up. If the distance of the camera to the code

band too large, the yellow LED5 lights up. Within the target range, the yellow LED5 flashes at the same time as the green LED2.

•Y coordinate: If the optical axis of the camera is too deep in relation to the middle of the code band, the yellow LED4 lights up. If the optical

axis is too high, the yellow LED4 extinguishes. Within the target range, the yellow LED4 flashes at the same time as the green LED2.

• A short press on button 1 ends the alignment aid and the reading head changes to normal operation.
