6.10. LED CURRENT ADJUSTMENT
The LED current is sensitive to the length of the light source module. With high LED current control
signals (above 150 with clean prism in air or above 200 in process) the length of the module can be
adjusted to decrease the current.
Note. The sensor should be checked first before adjusting the light source, See Sections 6.5 - 6.9.
Consult K-Patents or local K-Patents representative, if you are not familiar with the sensor check.
The length can be adjusted as follows:
– Remove the screw on the tightening ring in the middle of the module.
– Loosen the tightening ring.
– Rotate the module pipe one full turn to make the module shorter or longer.
– The LED current control signal decreases or increases as a result of modifying the length.
– The correct length of the module is the one that gives the lowest LED value for clean prism in air.
