When installing the photocell ensure that the detection is not confused by reflections, or

by poor light or colour contrast. The two LED lights on the photocell should only light once

as it detects the passage of the product. If this is not the case, adjust the sensitivity by

rotating the little screw either left or right (see manufacturers instructions).

2.1.4

Encoder installation

It is recommended to add an encoder to the system if :

the production line has an often varying or automatically varying speed

–

barcodes are printed.

–

In both cases it is recommended to install the encoder as close as possible from the

printing position of the printer along the conveyor, to minimize the elastic effects of the

conveyor belt.

Information for connecting the encoder to the controller and for operating the encoder can

be found in the controller manual.
