4. Start-up and tuning

Preliminary tuning can be done during installation at the actual place by simulating paper on situation with

dry paper on front of sensor head. Final tuning should be always done with real paper running situation.



Set unit to "Mode: Maintenance" in the "Configuration" menu.



Turn on the power.



Select from the "Maintenance" menu "On-line signals".



Turn the sensor head light beam so that signal levels are on their maximum values (normally 100 -

700) when simulating paper in front of sensor. Paper sheet should be close its correct position. Signal

level can be adjusted with "TX Power" and "RX gain" in the "Measurement config" menu. Ambient light

should be < 60 %.



Simulate break: Press "SAMPLE". Store signals as "Break level".



Simulate paper: When the paper is front of the sensor close to its normal position, press "SAMPLE".

Store signals as "Paper level".



Perform "Calculate Auto-limit" to find the best break detection signal.



Select the signal suggested by KPM KB2 pressing right arrow and "ENTER".



Select "Auto-alarm" to set the alarm signal Low/High limits. Drift alarm action, alarm limit and

direction should be set as well.



Activate the break relay by selecting operating mode ("Configuration" -

› "Mode"): "Detect

enabled".



Check that the position memory ring is locked.

5. Final tuning

Final tuning should be always done with real paper running situation and real break situation.
This time paper distance to the detector is stable and temperature as normal running temperature.



Select "Configuration" -

› "Mode"

› "Maintenance" (break relay deacti

vated).



While the machine is running without paper press "SAMPLE" and store signals as "Break level".

This can be done when the paper machine is warm and before paper sheet is on.



When the web (paper) is on press "SAMPLE" and store signals as "Paper level".



Perform "Calculate Auto-Limit" to find the best break detection signal.



Select the signal suggested by KPM KB2 by pressing right arrow and "ENTER".



Activate the break alarm relay by selecting operating mode ("Configuration" -

› "Mode"): "Detect

enabled".
