Introduction1.1

Read this Owner's Manual before using the Opti2 measure-

ment device and starting work. The Owner's Manual famili-

arises the reader with the features and operation of the

measurement device intended for harvester use. Reading

and understanding the instructions improves the utilisation

efficiency of the system and therefore increases work pro-

ductivity.

Also read the Owner's Manuals for the harvester head andbase machine.

This Owner's Manual applies to harvester head models X50,

H60e, H73e, H6, H7, H7euca and H8. If no specific harvester

head model is indicated in the heading of an instruction, the

instruction is applicable to all harvester heads.

General description of the Opti2 system1.2

The Opti2 is a control and measurement system that has

been designed for felling and cutting trees, recording output

statistics, and giving the driver information about the workflow

and the functionality of the system itself.

The Opti2 system controls the harvester head, tilt, feedrollers, delimbing knives and saw during the work.

The measurement device can be installed, for example, in

an excavator.

The Opti2 is comprised of four separate modules:seat module,

harvester head module,

bus distribution module (HUB),

and display module,

as well as a CAN bus and the controls: control wheel, control

buttons and preselection buttons.

The modules are connected to each other via the CAN bus.

Seat module1.3.1

The control wheel, control and preselection buttons are

connected to the seat module. The seat module identifies

the buttons pushed and the rotator handle control, as well

as sends information on buttons to the CAN bus.

Harvester head module1.3.2

The sensors and actuators of the harvester head are con-

nected to the harvester head module. The module controlsthe harvester head and reads the harvester head inputs

(sensors).

Bus distribution module1.3.3

The pumps are connected to the bus distribution module

(HUB) and, furthermore, the module monitors the currents

and the CAN bus.

Display module1.3.4

The display module compiles statistics and controls the

handling of logs. With the display module, the user can

monitor the system status and condition, and make system

adjustments. The display module collects data in the log file

regarding the system status and operation. All harvesting

data collected by the display module can be transferred to

the system printer, be recorded to a file in the display file

system, or be transferred as data to a memory stick via the

USB interface. The default display file system does not cre-

ate files.

The display module controls the status of the CAN bus and,if one of the modules is missing, the display informs the user,

and the system operation is limited.

The display module is controlled mainly with the control

wheel and its buttons. The display module's 5 buttons are

also used and the default functions of the display module

buttons are the same in all windows. If the function of the

display module buttons differ in some window, the button

has an icon at the bottom of the window. All windows have

an info window, which has a text description of the window

function and operations. The info window is activated using

display module button 5.

Measurement method, Continuousmeasurement of volume, i.e., cubing

1.5

The harvesting measuring method with this equipment is

based on continuous volume measurement. The volumeof the measurement batch is measured and calculated by

short logs and by means of the cylinder or truncated cone

formula. In practice, thickness readings are recorded in the

frame vector at one-centimetre (1 cm) intervals when feeding

a tree. The Opti2 screen module's memory contains a table,

always providing the volume of a one-centimetre-long trunk

corresponding to a specific thickness with an accuracy of

one-tenth of a millilitre. The final result is rounded to the

nearest decilitre.

The base of the first log after felling sawing is calculated by

forming a truncated cone.

When sawing using the topping saw, the unknown log section

is calculated on the basis of the prognosis prepared using

the log's realised narrowing.

For securing a reliable volume measure, the length and

thickness measures must be calibrated before starting themeasurement.

If the diameter is not in use, the measuring device will not

calculate the volume. Nevertheless, the harvester head must

be opened and closed before starting the work. This way

the preselections will function based on length alone.

Function, harvester head2

General2.1

The software of the measurement device assumes that trees

are felled in the following manner:

After turning the instrument On, the harvester head must

be first set to the Open and Close position and the

movement path must be correct with respect to its range

(sufficient number of pulses), before the diameter

reading appears on the screen (if the diameter is used).The measurement device does not calculate the volume

Opti2, version 1.62

6


10/82

if the diameter is not used. Even if the diameter is not

in use, the harvester head must be opened and closed

before starting the work. If the diameter is not in use,the preselections will function on length alone.

The harvester head is to be opened and lifted to a ver-

tical position, so that the tree to be felled can be caught.

Perform felling sawing.

The feeding starts with preselection, and also with

continuous feed from cut sawing. Using the manual feed

during the automatic feed will cancel the automatic feed.

The automatic feed can be restarted at any time by

pressing the preselection button.

As the feed is stopped at the correct dimension, sawing

is carried out (by pressing the button) and if the auto-matic feed is not selected, a new preselection is selec-

ted. When continuous feed is selected, but the minimum

diameter condition is not fulfilled, the feed will not start

automatically.

The sawing compiles statistics for the trunk's active

preselection. When a trunk counter is used, the trunk

is added to the preselection active during the first saw-

ing. The length reading is reset in sawing.

Feeding2.2

The measurement device selects the feed speed between

fast, medium and slow feed, based on the remaining dis-

tance. Fast speed is used when far away from the dimension.

Slow speed is used when close to the dimension. The speed

selection is affected by the braking distance + stopping

advance. When the distance to the dimension exceeds the

braking distance + stopping advance, fast feed is selected.

The stopping advance is the distance which the trunk moves

after stopping the control of the feed valves. The braking

distance defines how far before the target dimension the

feed is changed to slow speed.

Preselection2.3

The tree species and desired preselection table row are

selected with the preselection button.

Opti2, version 1.62

11/82

Preselections are pre-programmed data regarding the type

of logs desired. The preselection can already be selected

before carrying out the felling.

Preselection consists of seven different pieces of information:

Tree species; the botanical name of the tree in question.

Timber assortment; the end use of the log (e.g., log,

pulp or rot).

Length; the desired length of the logs to be cut.

Sawing window; the allowed deviation from the desired

length. A separate parameter for the under- and over-

shoot of the desired dimension.

Minimum tree top; the diameter in millimetres belowwhich the tree top diameter of the desired log must not

fall.

Colour marking.

Debarking (preselection activates the debarking mode,

if selected).

Free cutting.

When pressing Preselection after sawing, the harvester head

activates the preselection of the trunk feed to inform the

dimension, taking into consideration the tolerance and tree

top diameter. If the diameter falls below the tree top dimen-

sion, the trunk feed is stopped for this preselection. The user

must select a new preselection or feed manually using the

Feed forward button.

The log cut in sawing is statistically compiled during the

sawing for the active preselection. The running meters and

number of logs cut for each preselection are counted

together. The cubic meters are counted if the diameter is in

use, and the number of trunks is always counted. The num-

ber of trunks is always added to the preselection, for whichthe first log is made from the trunk.

A .prd file is made based on the statistical compilation data.

The user is not allowed to make the wrong preselection.

If the Plus/Minus function has been

activated using the parameter, the

functionality of the preselection buttons9 and 10 is changed so that preselec-tion button 10 is the Plus button andpreselection button 9 the Minus button.The Plus button is used to change thepreselet value to the preselection of the

tree species and assortment having a

length measurement closest to the cur-

rent length measurement and a target

length greater than the current length

measurement.

The Minus button is used to changethe preset value to the preselection of

the tree species and assortment having

a length measurement closest to the

current length measurement and a tar-

get length smaller than the current

length measurement.

If the Plus/Minus function is activated,

presets 9, 10, 19, 20, 29 and 30 aredeactivated and therefore shown in grey

in the Preselection window.

Safety lock3.3

S a fe t y lo c k sy m bo l a t t he t o p r i gh t .

The purpose of the safety lock is to disable the harvesterhead controls in connection with the system booting, as well

as when the driver is not in the cabin. The safety lock symbol

informing the driver about this is shown as locked in the main

menu of the display, and access to the Handling screen has

been blocked. Therefore, all harvester head controls are

also blocked.

The safety is activated when

- The Opti2 system is launched,- The base machine's safety switch/safety mode (usually

in the seat or cabin door) switches on,- Default settings are restored,

- The driver's own settings are taken into use,

- Or the saw chain change in the sequence ends.

The safety lock is opened, if necessary

- First by switching off the base machine's safety switch,

and

- by simultaneously pressing the Shift1 and Top sawcontrol buttons.

Harvester head functions4

The opening movement of the actuator is always dominant.

That is, if one tries to simultaneously close and open the

same actuator, the open control dominates and the actuator

is steered open. This applies to all harvester head functions.

operates for an open extended period of time. The auxiliary

vibration operates for as long as the button is pressed

regardless of whether the "automatic vibration" is in use ornot. When pressing the vibration button before the feed, the

extended open pulse is in use.

The Shift1+Vibrate buttons activate the "automatic vibration"of the front and rear delimbing knives. The vibration functions

that are active will operate. The automatic vibration symbol

of the front and rear delimbing knives appears on the screen.

The Shift2+Vibratebuttons open a window where it is pos-sible to select which vibration functions are active when the

automatic vibration is in use.

Rollers open4.1.3

When pressing the Rollers open button and the feed is turned

on, the program's default value is that only the knives will

open. However, the default value can be changed so that

the rollers will also open and the feed will be stopped.

The feed rollers are also steered fully open when the har-

vester head is steered fully open.

When felling, the Rollers open button fully opens the feedrollers. The feed rollers are opened for at least the time set

with the parameters, or for as long as the button is pressed.

The commissioning time, which lasts from the fully closed

position of the feed rollers to the fully open position, is

adjusted as a minimum control time parameter.

Pressing the Rollers open button briefly in sawing fully

opens the feed rollers, after which they close automatically.Pressing the Rollers open button for a long time in cuttingmode fully opens the feed rollers and they remain open until

the user closes them with, e.g., the Head close button or

the horizontal position starts the change sequence of thesaw chain for the active saw, during which the display

instructs the driver of actions to be taken.

The clearing function is activated using the Head open+Sawbutton with the harvester head in a vertical position.

The Head close+Saw buttons activate forced sawing. Thesaw blade stays out for as long as the Saw button is pressed.

Front knives open4.1.6

The front delimbing knives are also steered fully open or to

intermediate positions when the harvester head is steered

fully open or to intermediate positions.

If the saw or top saw stays out simultaneously when the

"front delimbing knives open" (or "knives open") control is

activated, the saw is first taken to the saw box and, when

the "saw home" data is active (saw in the saw box), the

knives will be opened.

automatically close.

Head close4.2.2

The Head close button fully closes the feed rollers, front

and rear delimbing knives.

When the Head close button is pressed, there are adjustable

delays (parameters) with the controls of the feed rollers and

rear delimbing knives. That is, first the front delimbing knives

are closed and, following the set delay, the feed rollers and

rear delimbing knives. For example, when pressing the

Knives close button, there will be no delay and the knives

will close immediately.

The Head close control stays on when the button is released.

The Shift1+Head close button closes the feed rollers, frontand rear delimbing knives to intermediate positions; in other

words they will remain closed for as long as the button is

pressed.

Reset length4.2.3

The Reset length button resets its current length reading.

Pressing the button for a long time deletes the output data

of the last cut log.

The Shift1+Reset length buttons (= New stem) switch theOpti2 system into a post-felling sawing state, even thoughno felling sawing was actually done. This can be used, for

example, if one needs to start cutting a trunk that has already

fallen or has been felled earlier.

Shift2+Reset length buttons. If the function has beenallowed using a parameter, the target length of the active

preselection is set as the length measurement. If the lengthmeasurement clearly shows incorrect lengths, the length

Opti2, version 1.62

measurement can be "forced" to the active preset target

length, which will lead to more accurate statistics. If no

preselection has been activated, the system will simultan-eously activate the default preselection and set its target

length as the length measurement.

In order for the previous function to work, delimbing paramet-

ers must be active. In addition, the DB section must beselected in the specific preselection. This function is mainly

used in delimbing harvester heads.

Tilt toggle4.2.4

The Tilt toggle button lifts the harvester head to the uprightposition / lowers the harvester head to a horizontal position.

Rotator/bucket selector4.2.5

The Rotator/bucket selector button activates the rotatorcontrol when the bucket control is in use. Pressing the button

when the rotator control is in use activates the bucket control.

Top saw4.2.6

The Top saw button changes the top saw as the saw to beused. The selection is cancelled by pressing the button for

the second time. The selection is automatically cancelled

when the harvester head is opened and the top saw has

sawed. (The top saw function requires that the use of the

top saw is allowed using a parameter.)

The Shift1+Top saw buttons open the safety lock.

Slow feed forward4.2.7

While pressing the Feed forward button, trunks are fed at

high speed forward.

The trunk feed speed is limited to a maximum average

speed, if the trunk is taken in the harvester head during

felling sawing.

The trunk feed forward is prevented when the saw or topsaw is out of the saw box.

Opti2, version 1.62

21


25/82

While pressing the Shift1+Feed forward buttons, trunks are

fed at slow speed forward.

The trunk feed forward is prevented when the saw or top

saw is out of the saw box.

Slow feed backward4.2.8

While pressing the Feed backward button, trunks are fedbackward at high speed.

The feed speed is limited to a maximum average speed, if

the trunk is taken in the harvester head during felling sawing.

The trunk fast feed backward is prevented when the saw or

top saw is out of the saw box.

While pressing the Shift1+Feed backward buttons, trunksare fed at slow speed backward.

When the saw or top saw is out of the saw box, only a slow

speed backward of the trunk is allowed.

Default preselection4.2.9

The Default preselection button activates the default

selection.

Butt end4.2.10

Butt end debarking is carried out by pressing the Butt endbutton with the debarking mode active (parameter) or

debarking allowed in the preselection. In butt end debarking,the harvester head must be in the cutting mode.

When pressing the Butt end button, the trunk is fed backward

until the target length is achieved or is undercut.

Butt end debarking can be aborted with the Feed forward

and backward buttons, as well as by pressing the Butt end

button for the second time.

Butt end delimbing: After cutting, press the Butt end button

before the first preselection. After the first preselection,automatic butt end delimbing is carried out.

Opti2, version 1.62

22


26/82

In butt end delimbing, the part of the butt end which remains

outside the delimbing knives in connection with cutting the

trunk is to be delimbed. In butt end delimbing, the trunk isfed backward to the length defined with the average speed

parameter, after which the automatic cut-to-length is activ-

ated.

Butt end delimbing is available when the automatic feed or

preselection feed mode is selected.

Butt delimbing and the following automatic cut-to-length can

be aborted with the same buttons with which the automatic

cut-to-length is aborted. If it is desired to cancel butt

delimbing in the middle of delimbing but continue the auto-matic cut-to-length, then this is done by pressing the Butt

end button again.

The Shift1+Butt end function is used to locate the trunk buttend, that is, the zero point of the length, when the length

measurement is missing. The function requires that the

harvester head includes a butt end identification sensor. The

Butt end function feeds the trunk at average speed.

If the butt end identification sensor is active at startup of the

Butt end function, the trunk is fed backward until the identi-fication sensor changes mode, in which case the trunk feed

direction changes to forward and the speed to slow. When

the identification sensor changes mode again, the trunk feed

is stopped.

If the butt end identification sensor is not active at startup of

the Butt end function, the trunk is fed forward at average

speed, until the identification sensor changes mode and the

trunk feed is stopped.

Every time the butt end identification sensor changes mode,

the length display shows the distance from the sensor to the

saw.

The butt end search function is active regardless of the

selected feed mode.

The butt end search function can be aborted in the middle

of the butt end search by pressing the "feed forward" or "feed

backward" button or by starting the automatic cut-to-length.

The Butt end search function is automatically aborted whenactivating the slipping identification.

Calibration5.3

Length measurement calibration5.3.1

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.

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 curve5.3.3

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.

D i a me t e r c u r ve .

The Graphbutton 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 handle5.3.4

Handle calibr ation, 2 potentiometer s.

The rotator control handle must be calibrated whenever therotator 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.

1. Select 3. Calibration -> Rotator lever.

2. Move the right hand side handle sideways to both

extremes several times. The bars on the screen mustmove 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 calibr ation, 2 potentiomet-

er s

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.

1. Select 3. Calibration -> Extension calibration2. 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 oneof 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.

calibrated?" = Has the harvester head's pressure sensor

been calibrated? Continue by pressing OK, using thecontrol wheel's green button.

5. The program prompts you to turn on the machine's

working RPM. After setting the working RPM, press the

control wheel's green button.

6. Next, press the handles' Head Close button, i.e., closethe harvester head.

7. The program starts to prepare the installation. The

screen displays Preliminary Preparations...8. After the preparation, the program will perform a pres-

sure measurement for the front knives. CalibratingFront knives... The program measures the front knifepressure using ten increasing currents.

9. After the pressure measurement, the program asks if

you accept the measurement. Press the control wheel's

green button if you wish to use the machine's measure-

ment results. The front knife pressure calibration is now

complete.

opening time is extended when the Vibrate control buttonis pressed before starting the feed.

Parameters affecting the vibration ofthe front and rear delimbing knives(X50, H60, H73)

6.5



The delimbing knives vibration refers to the successive

sequential openings and closures of the front and/or rear

delimbing knives, which occur several times upon feeding

the trunk. This allows easier trunk movement in the harvester

head.

1. Select 4. Settings -> Parameters -> Knives vibration.2. Adjust the values the way you like.

Min open:Indicates in milliseconds the time for which the delimbing

knives open when the trunk diameter is the same or smaller

than the diameter set in Min .

knives open when the trunk diameter is the same or greater

than the diameter set in Max .

Close:Indicates in milliseconds the time in which the delimbing

knives close during vibration. The same time is applied to

all diameters.

If the diameter of the tree is between the Min (cannot be

adjusted) and Max values, the opening time used for thedelimbing knives vibration feature adjusts linearly between

the Min and Max values based on the diameter of the

tree.

The delimbing knives will not vibrate at all if the trunk dia-

meter is greater than the diameter set in Off .

Extra opening:Indicates as a percentage by how much the delimbing knives

opening time is extended during vibration when the Vibrate

control button is pressed during the feed. The extendedopening time is in effect until the Vibratebutton is released.
