Setting the Lighting Angle
For optimal detection of the perforated matrix, code sheets must be illuminated at a certain
angle to achieve maximum contrast between the holes and the metal plate. The angle must be
set manually depending on whether you use CB1 or CB3 code sheets. The lighting unit is
mounted on a rail in the OIT housing. The lighting unit can be moved to the right position using
a scale.
The lighting unit is preset for the CB1 code sheet as the factory default.
Setting the Lighting Angle to CB3 Code Sheets
1. Disconnect the device from the power supply.
2. Unscrew the enclosure cover.
