Overview
In this program module you set all the times and values of variables that adapt the computer to various harvester heads, operating mode and operator. The number and configuration of the variables are unique for each make of harvester head.
Variables are saved in files with the suffix ".mas" and each operator can create an individual ".mas" file. This option allows each operator to program the desired times and variables individually. Authorization for programming of variables may vary for different operators. The next operator activates the correct ".mas" file automatically.
DCL
The DCL program is a separate program that is not included in this description. The DCL programming is made of the functions that control the harvester head. The functions can be "Feed forward", "Feed reverse, or" "Saw" for example.
The program defines exactly which valves and other control systems that are to come into action when the relevant function is activated. The program also decided whether the function is to include a variable giving the operator the option of affecting the function.
Here is also where the variables are put into groups and sub groups.
Variable Description
Variables can be programmed individually by each operator. To simplify the programming, the variables are divided into various groups.
The groups of variables can be divided into subgroups if desired.
The variables can be divided into five different types:
- Variable with numerical value
- Variable with numerical value and controlled output
- Variables have the choice between the options to be active or inactive.
- Variable have the choice between several options that can be selected individually or several various options
- Matrices or tables with one or several columns.
Note: During the programming the operator can see directly how the various values will affect the actual function.

Note: Too high of a value may cause overspeeding, cutting window overshoot and/or component damage. Too low of a value will result in longer processing times.
Forward Breakpoint Speed
Milliampere are supplied to the feed forward solenoid valve when tree reaches break point.
Note: As a tree is being fed, the feed speed will be reduced when the break point is reached. The feed speed will decrease to prevent overshoot of the cutting window. Setting the break point speed too high will over shoot the cutting window. Setting the break point speed too low will result in longer processing times.
Forward Minimum Speed
Sets the minimum milliampere supplied to the feed forward solenoid valve when the tree is approaching the cutting window. The lower the value the slower the roller speed.
Note: Too high of a value will cause a measurement overshoot. Too low of a value will result in longer processing times or tree stall. Set this speed so that a log will be fed at the slowest speed possible.
Forward Crawl Speed
Sets value in milliampere supplied to the feed forward solenoid valve during slow manual forward feeding.
Note: Set to the preference of the operator. Increasing the milliampere will increase the speed. Decreasing the milliampere will decrease the speed.
Reverse Maximum Speed
Sets the maximum milliampere that is supplied to the feed reverse solenoid valve. The higher the value the faster the roller speed.
Note: Too high of a value may cause overspeeding, measurement overshoot and/or component damage. Too low of a value will result in longer processing times.
Reverse Breakpoint Speed
Milliamperes are supplied to the feed reverse solenoid valve when tree reaches break point.
Note: As a tree is being fed in reverse, the feed speed will be reduced when the break point is reached. The feed speed will decrease to prevent overshoot of the cutting window. Setting the break point speed too high will overshoot the cutting window. Setting the break point speed too low will result in longer processing times.
Reverse Minimum Speed
Sets the minimum milliampere supplied to the feed reverse solenoid valve when the tree is approaching the cutting window. The lower the value the slower the roller speed.
Note: Too high of a value will cause a measurement overshoot. Too low of a value will result in longer processing times or tree stall. Set this speed so that a log will be fed at the slowest speed possible.
Reverse Crawl Speed
Sets the value in milliampere that are supplied to the feed reverse solenoid valve during slow manual reverse feeding.
Note: Set to the preference of the operator. Increasing the milliamperes will increase the speed. Decreasing the milliamperes will decrease the speed.
Reverse Speed to Photocell
Sets the milliamperes that are supplied to the feed reverse solenoid valve when the "end find" function is selected. The higher the value the faster the roller speed.
Note: Too high of a value may cause overspeeding, measurement overshoot and/or component damage. Too low of a value will result in longer processing times.

Brake Distance
Brake distance is the distance, in centimeters, from the brake point to the point where minimum speed feeding begins.
Note: Setting the brake distance too short will overshoot the cutting window. Setting the brake distance too long will result in longer processing times.
Speed Filter
Filter for the displayed value in machine variable settings for Fwd Max and Min speed settings. A low percentage causes a rapid update of the value. A high percentage causes slow response in the updating of the value.
Max Slope Speed
Set according to displayed value from "Viewing the Measured Speed". Use the feed forward key.
Note: The minimum and maximum speeds must be set as close to the measured speed as possible. These values allow the calculation of the "Calculated Speed" for each position along the slope length.
Min Slope Speed
Set according to displayed value from "Viewing the Measured Speed". Use the feed forward key and the override key.
Note: Set "Fwd crawl speed" equal to "Fwd Min Speed" before you collect the value.
Max AS Comp (p.m.)
Creates the base regulating area, in the shape of a funnel around the classic slope. This area cannot be exceeded by the calculations for compensation.
Min AS Comp (p.m.)
Creates a tube or spout area around the classic slope. This area is merged with the funnel from "Max AS Comp" factor. Together, the factors create the shape of the total regulating area. A smaller regulation close to the target is prevented or allowed.
Comp Term
The value controls the output effect of the speed. If the value is high, the output correction will be a low value. If the value is "1", the correction value will follow the edge of the regulating area if "Current Speed" and "Calculated Speed" differ.

| Illustration 25 | g02274113 |
Jam Protection
The jam forward function is either ON or OFF. When the function is ON, the head will automatically change direction and refeed the tree when the head stalls against a limb during reverse feeding.
Start Length
Length in centimeters from the butt, where the jam protection will active. If a jam occurs in this defined area, the head will not reverse the tree automatically. This precaution is done in order to prevent the tree from feeding out of the lower knives.
Sensitivity
Time in milliseconds, once the jam occurs, that the controller waits before activating jam protection. Set sensitivity so that sufficient time is allowed to power through larger limbs.
Note: Too short of a time will cause unnecessary reverse and forward feeding. Too long of a time will result in longer processing times.
Reverse Speed at Jam Forward
Milliampere are supplied to the feed reverse solenoid valve when tree jams.
Note: Set to the preference of the operator. Increasing milliampere will increase speed, decreasing milliampere will decrease speed.
Reverse Length at Jam Forward
Once the tree jams, the distance in centimeters that the tree will reverse before forward feeding resumes.
Note: Too low of a value will cause unnecessary reverse and forward feeding. Too high of a value will result in longer processing times.
Feed Reverse Time at Jam
Allowable time is in milliseconds, that the controller will wait to meet the reverse length target.
Note: If reverse length at jam forward is not reached within the defined time limit, forward feeding will resume.

Jam Protection
Function is either ON or OFF. When the function is ON, the head will automatically change direction and refeed the tree when the head stalls against a limb during reverse feeding.
Sensitivity
Once the jam occurs, the controller waits before activating jam protection. The time is in milliseconds. Set sensitivity so that sufficient time is allowed to power through larger limbs.
Note: Too short of a time will cause unnecessary forward and reverse feeding. Too long of a time will result in longer processing times.
Speed
Milliamperes are supplied to the feed reverse solenoid valve when tree jams.
Note: Set to the preference of the operator. Increasing milliampere will increase speed, decreasing milliampere will decrease speed.
Feed Length at Jam
Once the tree jams, the distance in centimeters that the tree will forward feed before reverse feeding resumes.
Note: Too low of a value will cause unnecessary forward and reverse feeding. Too high of a value will result in longer processing times.
Feed Time at Jam Reverse
The time that the controller will wait to meet the feed length target is in milliseconds.
Note: If the feed length at jam reverse is not reached within the defined time limit, the reverse feeding will resume.
Feeding
| Factory Settings for the Feeding | |
| Feeding Variable | Factory Variable Setting |
| Acceleration at start | 0 |
| Fwd. M Slope Down Time | 15 |
| Rev. M Slope Down Time | 15 |
| Stop distance Cushion Fwd. | 3 |
| Stop distance Cushion Rev. | 3 |
| Rev. Debark Distance (cm) | 45 |
 | |
| Illustration 27 | g02278654 |
Acceleration at Start
Time is in milliseconds from minimum current output to maximum current output to the feed roller solenoid valve "ramp".
Note: Too short of a time will accelerate the feed rollers to maximum speed too quickly and cause feed roller slippage. Too long of a time will increase processing time and may result in jamming.
Forward Manual Slope Down Time
Once the manual forward feed button is released, milliamperes are supplied to the forward feed solenoid valve.
Note: Setting the slope down time too short will result in an abrupt feed stopping. Setting the slope down time to long will result in the tree drifting to a stop.
Reverse Manual Slope Down Time
The time is in milliseconds, between maximum milliampere and minimum milliampere supplied to the reverse feed solenoid valve once manual feed button is released.
Note: Setting the slope down time too short will result in an abrupt feed stopping. Setting the slope down time to long will result in the tree drifting to a stop.
Stop Distance Cushion Forward
The distance is in centimeters, from feed forward stop to desired cut length.
Note: Too long of a distance may damage hydraulic components, max value is equal to 15 units and the normal value is equal to 0.
Stop Distance Cushion Reverse
The distance is in centimeters, from feed reverse stop to desired cut length.
Note: Too long of a distance may damage hydraulic components, max value is equal to 15 units and the normal value is equal to 0.
Rev. Debark Distance
Distance in centimeters that the head will reverse feed the tree to a negative length after the key function "Debark Butt" is depressed. The function is utilized to reverse feed the tree automatically the specified negative distance to debark the lower portion of the tree. Too large of a distance will cause the tree to reverse feed out of the rollers. Too small of a value will result in ineffective debarking of the lower portion of the tree and increase processing times. The function speed utilizes the "Rev. Crawl Speed" setting and disables automatic processing when performing the reversing sequence.

Delay Rollers Close
Time in milliseconds before feed rollers begin to close after "all close" function has been activated.
Note: Too short of a time may cause poor tree placement in the head. Too long of a time will result in longer processing times.
Delay Rollers Open
Time in milliseconds before feed rollers begin to open after "all open" function has been activated.
Note: Too long of a time will result in longer processing times.
Opening Time, Rollers
Time in milliseconds that the controller energizes the feed roller open solenoid valve.
Note: The time should be set long enough in order to ensure that the feed rollers fully open when "all open" function is engaged. "All open"function only.
Automatic Pulse Open Multi Stem Mode
Time in milliseconds, that the feed rollers will pulse open to allow a second tree to be grabbed in multi stem applications.
Note: Too short of a time will not allow the roller arms to open far enough in order to allow a tree to be grabbed. Too long of a time will result in longer processing times.
Pulse Open Before Cut
Time, in milliseconds, that the feed rollers are allowed to pulse open after the head has stopped in the cutting zone. The tree is pulled tight against the frame of the head, reducing the amount of saw kerf to the log. During this time, increased knife pressure will be applied to pull the tree tight against the frame. All other automatic functions are disabled during this process. Set this value to "0" to disable this function.
Rev Time at Saw Bar Jam
Time, in milliseconds, that the feed reverse function is automatically activated during the saw bar jam sequence. The saw bar jam sequence allows the saw bar to be fully extended while the tree is reverse fed. This extension allows the saw bar to return to the saw home position without getting caught on the saw log.

Maximum Time
The allowable time that the controller will wait to meet the maximum saw bar out distance is in milliseconds.
Note: In case the maximum saw bar out is not reached within the defined time limit the alarm will be displayed.
Maximum Diameter
The maximum diameter determines the maximum saw bar out distance that is used as the target for Max saw time warning.
Note: When set too low, a false alarm will occur. When set to high no alarm will occur. Setting this variable to equal 0 disables this function.
Error Time Saw Prox
The allowable time before the saw time warning function is enabled is in milliseconds.
Note: Error times set too short will cause saw time warning false alarms to occur. Error times set too long will delay notification of legitimate saw feed errors.

Diameter Limit Cut to Matrix
Pausing the automatic processing, allows the operator to move the position of the head in order to facilitate easier sorting for different log values. These values of log diameter are user-defined in millimeters.
Note: The automatic process is initiated by the operator performing a semi-automatic cut. Setting this variable to equal 0 disables this function.
Delay Auto Cut
The time from when the tree reaches the cut target to when the saw engages is measured in milliseconds.
Note: Too short of a time may result in saw bar and chain damage. Too long of a time will result in longer processing times.
Note: The delay auto cut function is only valid for the automatic cut function when the automatic cut function is performed during matrix cutting.
Oiler Time ON
The time that the saw chain oiler will pulse ON when the saw is activated is measured in milliseconds.
Oiler Time OFF
The time that the saw chain oiler will remain OFF between chain oiler ON pulses when the saw is activated is in milliseconds.
Note: Oiler time functions are only valid when the head is equipped with an electronic chain oiler.
Max Bar Return Time
Maximum time allowed, in milliseconds, for the saw bar to return to the home position before automatically extending to the fully extended position. At this time, the feed rollers will reverse feed the tree for the time value specified in "Rev Time @ Saw Bar Jam". After the feed rollers function is complete, the saw bar will safely return to the home position in the saw box. Too low a value will cause the saw to extend completely. Too high a value may result in saw bar jamming.

| Illustration 37 | g02274597 |
Slope Down Time Saw Motor
Time in milliseconds for deceleration from "Min speed" to "Max speed" for butt saw chain.
Note: Too high of a value may increase processing time. Too low of a value may cause bar and chain wear/damage. Normal values equal 8 to 15 units.
Slope Up Time Saw Motor
The time for acceleration from "Min speed" to "Max speed" for the butt saw chain is in milliseconds. The saw bar remains in the home position until the slope up time expires.
Note: Too high of a value may increase processing time. Too low of a value may cause bar and chain wear/damage. Normal values equal 8 to 15 units.
Minimum Saw Motor Speed
The minimum milliamperes that are supplied to the butt saw motor solenoid valve where chain begins to move.
Note: Set this value so that the chain spins as slow as possible.
Maximum Saw Motor Speed
The maximum milliamperes that are supplied to the saw motor solenoid valve.
Note: Too high of a value will overspeed the motor and reduce the chain life and/or throw the chains. Too low of a value will increase the cutting time resulting in longer felling, and cross cutting times.
Pulse On - Bar feed
Time in milliseconds in the frequency loop when the saw motor is "On". Frequency loop is designed to slow down saw bar feed speeds in the first part of the saw cut. The speed increases after the midpoint and reduces the chances of incurring a saw crack in the log. The frequency loop consists of time-specific pulses which determine the duration the saw is "on" and "off" during cutting. (test purposes)
Pulse OFF - Bar feed
Time in milliseconds in the frequency loop when the saw motor is "Off". This variable is more "critical" than the "on" pulse variable: Too low of a value will result in no performance differences. Too high of a value will result in inconsistent bar feeding (the bar will begin to bounce during feeding) and may cause component damage. The Fequency Loop is designed to slow down saw bar feed speeds in the first part of the saw cut. The speed increases after the midpoint and reduces the chances of incurring a saw crack in the log. The Frequency Loop consists of time-specific pulses which determine the duration the saw is "on" and "off" during cutting. (test purposes)
Full Speed Breakpoint
Percentage of current butt saw tree diameter where the intermittent saw pulsing sequence ends and the butt saw completes the cut at full speed. Setting the value to low will cause the saw to reach full speed too late and saw cracks are likely to occur. Too high of a value will cause the saw to cut most the log utilizing full speed. The saw will not provide the desired function to reduce saw cracking. The sequence is "Off" when the tree diameter is lower than "Diameter Limit for Alarm (mm)" (for test purpose).

Auto Feed After Cut
In the OFF position, feeding must be initiated manually after the first cut. In the ON position, auto feed will start automatically after the first cut is completed. The automatic feeding will not start when the manual length button is selected. When the position is not set to first log, the auto feed will not start after first log is cut. The remaining logs will auto feed.
Tree Species Repeat
In the ON position, the designated "tree species" function button on the joystick is not reselected after each tree is processed. In the OFF position, the designated "tree species" function button on the joystick must be selected before processing another tree.
Start Auto Processing
In the hold position, the designated "start" function button on the joystick must remain depressed while processing. In touch position, the designated "start" function button on joystick is depressed and then released to start processing.
Overshoot Length
The distance that a tree will be fed past the cutting window, before backing up and cutting is called overshoot.
Note: Too short of a distance may not delimb a sufficient amount of distance on the next log to ensure ease of startup acceleration. Too long of a distance will result in increased processing time.
Start at Tree Species
In the ON position, the processing will begin at the designated "tree species" button selection. In the OFF position, the start button will need to be selected after the designated "tree species" button is selected.

Step During Feed
The defined action when the controller determines that the current tree does not meet the qualifications during feeding. The qualifications for the lengths are inputted in the bucking instructions.
Note: Based on precalculated forecast. Set to "stop"is recommended.
Step at Wrong Choice
The action at wrong manual length choice is to stop the automatic cutting or recount and continue cross cutting from the bucking list.
Note: Set to "stop" is recommended.
Step at Minimum Top Diameter
The action when the minimum top diameter is reached. The minimum diameter value is automatically extracted from the bucking instructions.
Note: Set to "stop" is recommended.

| Function during feed | Pause |
| Delay reset at knife open | 90 |
 | |
| Illustration 40 | g02273973 |
Sequence Mode
The sequence function is either ON or OFF. In the ON position, this selection allows the "all close" function to be utilized as the "saw" function and the "start" function. After grabbing a tree and keeping the "all close" function depressed, the sequence mode is activated. Releasing, and reselecting the "all close" function will perform a fell cut. Releasing and reselecting the "all close" function again after felling, will start automatic processing.
Note: Manual saw activation must be used for cross cutting if "Cut type automatic" is not selected.
Delay at Fell Cut
The delay time is in milliseconds between the "all close" and the "start" of the felling cut in the sequence.
Diameter Limit at Felling
The percentage of the butt diameter that must be reached during the felling cut before the sequence will continue to "start auto feeding". In the occurrence that the felling cut does not exceed the diameter limit, the sequence mode will stop.
Extra Fell in Sequence
The "extra fell in sequence" function is either ON or OFF. The ON position allows for multiple felling cuts to be made with the "all close" button.
Note: The sequence mode must be ON.
Function During Feed
The "Function During Feed" function allows the "all close" function to be used as a stop or pause function during automatic feeding. When set to pause, and the "all close" function is selected during feeding the feeding will be suspended until the "all close" function is released. When set to stop, and the "all close" function is selected, the "start" function must be utilized to resume feeding.
Delay Reset at Knife open
The time the feed rollers will delay opening when the "all open" function is depressed if feeding is still active is in milliseconds.
Note: Too low of a value will not provide sufficient time for the knives to open before the feed rollers open. Too high of a value will increase the processing time.

| Illustration 41 | g02272796 |
Alarm at Cutting Window
The function is either ON or OFF. When the function is ON, an audible alarm notifies the operator when the tree is within the desired cutting window. The saw can then be activated.
Diameter Limit for Alarm
For an audible alarm to sound when the "alarm at diameter limit" is activated a diameter value must be specified in millimeters.
Alarm at Diameter Limit
The function is either ON or OFF. When in the ON position, and the diameter falls below the specified value, in millimeters, an audible alarm will sound to notify the operator.
Length Pulses per Meter
"Length Pulses per Meter" is the number of pulses per meter recorded by the length measuring wheel. Modify the value if the manual measurements differ more than 2.54 cm (1 inch) from the controller measured values. When the actual measured value is greater than the controller measurement, decrease the pulses per meter. When the actual measured value is shorter than the controller measurement, increase the pulses per meter.
Note: Small changes in pluses will result in a large change in calculated length.
Disable Diameter Encoder
The "Disable Diameter Encoder" allows the operator to disable one encoder if malfunction, failure, or damage occurs. This option prevents the operator from having to perform a new diameter setup and normal operation can be continued. By disconnecting an encoder input, the remaining encoder will generate double diameter address values.
Note: Encoder should be replaced/ repaired as soon as possible to prevent a situation where both encoders are inoperable.
Roller Length Mode
Determines the method used to interpret the signals received from the two feed roller encoders for length measuring.
"LEAST" mode analyzes both left and right encoder signals instantaneously and does not increase length unless only one pulse is received from each encoder. If a feed roller slips or spins on the tree, the measurement will not progress until receiving a signal from the stationary encoder. The values of the spinning roller will not be recorded.
"MOST_____AVERAGE" mode analyzes both left and right encoder signals for 20 milliseconds. The length is calculated using the average value of both encoders during that timeframe.
"SLOWEST" mode analyzes both left and right encoder signals for 20 milliseconds. The length is calculated using the encoder which has moved at the slowest speed during that timeframe.
"FASTEST" mode analyzes both left and right encoder signals for 20 milliseconds. The length is calculated using the encoder which has moved at the fastest speed during that timeframe. Priority is given to the two length measuring encoders in the feed wheels.
All Close Timer
Time, in milliseconds, allowed for the knives and feed rollers to close completely around a tree prior to the start of feed roller length measurement. The timer begins when the "All Close" function key is depressed. Too long of a time will increase processing time and result in short lengths. Too short of a time will result in longer than desired log lengths. "Start Auto Processing" is enabled once the "All Close Timer" ends.
Roller Measure Status
When set to "Disable", the machine ignores any values generated from the feed roller length encoders when the following conditions are present:
- The head is open.
- The head is tilted up.
- The tree diameter is smaller than "Min. Top Diameter".
The symbol for "Harvester mode" starts to flash when the length measure is disabled. When set to "Enable", the feed roller length measuring devices will record length whenever the feed rollers are rotated. The chance of length measuring errors is increased.

Depress "enter" to store the value and deactivate the function.
Rotator Start Ramp
Time from minimum to maximum current output to the rotator solenoid valve is measured in milliseconds.
Note: Too low of a value will accelerate the rotator to maximum speed too quickly and may cause component damage. Too high of a value will increase the rotation time.
Rotator Stop Ramp
Time from maximum to minimum current output to the rotator solenoid valve is measured in milliseconds.
Note: Too high of a value will increase the rotation time. Too low of a value may cause an abrupt stop or component damage.

Delay Tilt Up
The time allowed for the delimbing knives and feed roller arms to reopen before the head tilts up after the "all open" function activates. The time is measured in milliseconds.
Note: Too small of a value may cause the head to tilt before all trees have been dropped. Too large of a value may cause increased processing time.
Diameter Limit Tilt Float at Fell
The diameter that determines when the head will auto float after the saw leaves the home position is in millimeters.
Note: Too high of a value will cause head to hold large trees after felling and may cause equipment damage. Too small of a value may damage smaller trees.
Auto Tilt Up at Opening
The function is either ON or OFF. When in the ON position, the head is allowed to tilt up automatically when the "all open" function is selected. When in the OFF position the operator is required to tilt the head up manually.
Auto Tilt Up at "Finish"
The function is either ON or OFF. When in auto processing mode, the ON position allows the head to tilt up automatically when the final cut has been completed. The ON position also allows the head to tilt up automatically when the "finish" is active at "Action at...".
Time Tilt Up
The time that the controller energizes the tilt solenoid valve is measured in milliseconds.
Note: Set value long enough to ensure that the head fully tilts up when the "all open" function or "tilt up" functions are engaged.
Tilt Floating OFF Diameter
The measured diameter is in millimeters when the tilt float function is disabled during processing. Not floating while large tree is being harvested/processed will result in equipment damage. Only small diameter trees should utilize the tilt float OFF function.
