Calibration 5.3
Length measurement calibration 5.3.1
This display can be used to correct length measurement data. Any incorrect measurement is corrected, or the desired length measurement data is calibrated, by measuring the last cut short log manually.
The length measurement calibration must be performed for all tree species cut separately.
1. Make a short log which is over one metre in length. The last made log will do, if the device has not been switched off in between the functions.
2. Measure the length of the log using a tape measure.
3. Go to 3. Calibration -> Length.
4. Ensure that the system has suggested the correct tree species. If not, select the tree species of the measured short log using the control wheel and press the green button.
5. Adjust the length if necessary.
6. Save the calibration by pressing the green button.
Calibrating the diameter sensor range 5.3.2
1. Go to 3. Calibration -> Diameter range.
2. Close (0 pulses) and open the harvester head until the maximum pulse value remains almost unchanged (between 450 and 550) when the harvester head is fully open. Normal variation of the maximum value is +/- 1 pulse.
3. Save the maximum value using the control wheel's green button. If the value has decreased or changed when saving, the calibration must be performed again.
4. The use of the diameter sensor's new calibration value can be prevented by pressing the control wheel's red button.
Calibrating the diameter curve 5.3.3
The display will show the length and diameter measurement data of the short logs from the last handled trunk as calcu-lated by the device. Then measure the same short logs manually and compare the data. If the value calculated by the device differs from the manually measured data, this is to be fixed this using the device. The minimum number of measuring points in use is 2 (diameter curve = straight line) and the maximum number is 20.
on/off:
The measuring point is enabled by checking the box or dis-abled by removing the check mark.
Length:
The measuring points are given in the format x/yyy, where number x indicates the sequence number of the short log, starting from the butt log whose sequence number is 1.
Number yyy indicates the measuring point in centi-metres/inches measured from the butt end of the log in question. In other words, measuring point 3/482 refers to a point which is 482 cm/inches away from the butt end of the third log. If the measuring point numbers are replaced with a '-' character, the last log has not included that specific diameter class.
Diameter:
The diameter used by the system for that specific diameter class is indicated in millimetres/inches.
Diameter curve.
The Graph button allows you to open a graph representing the current calibration curve.
Before diameter calibration, the operator must ensure that the length measurement and diameter sensor range are correct. If necessary, these need to be calibrated first.
1. Cut the whole trunk into short logs, if you have not done this already.
2. Select 3. Calibration -> Diameter curve.
3. Use the Print button to print out the measuring points and values or write them down on a piece of paper.
4. Measure the short log diameters with measuring cal-lipers at given measuring points.
5. If necessary, adjust the diameter values. You can only adjust the diameter classes in use. Classes can be activated or deactivated by checking or unchecking the on/off column.
6. The settings will be saved and implemented once you exit the screen.
Calibrating the rotator handle 5.3.4
Handle calibration, 2 potentiometers.
The rotator control handle must be calibrated whenever the rotator pressure sensor has been replaced or the feel for the rotator's controls has become strange or different.
Left/CCW:
Extreme left position of the steering handle (= maximum voltage value).
Right/CW:
Extreme right position of the steering handle (= maximum voltage value).
Voltage values (V):
The voltage values on top of the bars represent "the current voltage value" and the voltage values on the bars' pages represent the voltage values of the extreme positions, that is, the calibration values, when the steering handle is turned right or left.
OK:
Saves the adjusted values to the module and the program returns to the previous display.
Handle calibration, 1 potentiometer.
1. Select 3. Calibration -> Rotator lever.
2. Move the right hand side handle sideways to both extremes several times. The bars on the screen must move in the same direction as the steering handle. If the bars are moving in the opposite direction, the pres-sure sensor channels are crossed. Check the correct connection from the electrical diagram (Installation instruction, Appendix 4). The voltage values must be stable when the handle is in the middle or at either extreme position. If the voltage values fluctuate a lot, check the sensor wiring, connections and the stability of the pre-control pressure.
3. The settings will be saved when you exit the screen by pressing the green button. If you press the red button, the old calibration values will remain in effect.

Extension calibration (if the machine is equipped with an extension)
5.3.7
Extension calibration, 2 potentiomet-ers
The extension is calibrated automatically when taking a new harvester head into use. The extension must also be calib-rated whenever the pressure sensors have been replaced or the feel for the extension's controls has become strange or different.
In:
Calibration of the retraction of the extension control handle (= maximum voltage value).
Out:
Calibration of the ejection of the extension control handle (=
maximum voltage value).
Voltage values (V):
The voltage values on top of the bars represent "the current voltage value" and the voltage values on the bars' sides represent the voltage values of the extreme positions, that is, the calibration values, when the extension is controlled in or out.
OK:
Saves the adjusted values to the module and the program returns to the previous display.
Extension calibration, 1 poten-tiometer.
1. Select 3. Calibration -> Extension calibration
2. Move the extension handle sideways to both extremes several times. The bars on the screen must move in the same direction as the steering handle. If the bars are moving in the opposite direction, the pressure sensor channels are crossed. The voltage values must remain stable when the handle is in the middle position or one of the extreme positions. If the voltage values fluctuate a lot, check the sensor wiring, connections and the stability of the pre-control pressure.
3. The settings will be saved when you exit the screen by pressing the green button. If you press the red button, the old calibration values will remain in effect.
Movement-specific pressure calibration (H6, H7, H7euca, H8)
5.3.8
Pressure sensor, i.e., the calibration of the harvester head's pressure transmitter, must always be performed before cal-ibrating the movement-specific pressure sensors. This action can only be performed by the Ponsse service personnel.
The pressure sensor has normally been calibrated when implementing the harvester head.
Before starting calibration, steer the harvester head to a horizontal position, i.e., the grapple must be in the processing mode. Make sure that no unauthorised persons are in the machine danger zone.
1. Select 3. Calibration -> Pressures.
2. Press the control wheel's green button, and select OK
= Automatic calibration.
