If you read these instructions carefully and keep them in mind, you can more easily utilize the system efficiently and thus increase the productivity of the forest machine. 1.2 EPEC Products The Epec products are control and measuring systems manufactured by Epec Oy and intended for use in forest machines. The very newest technology in this branch has been utilized in the design and manufacture of these systems. We have paid special attention to the reliability and accuracy of the function in exacting conditions and, in spite of equipment versatility, easy operation. The Epec products have been developed in close co-operation with forest machine manufacturers, forestry companies and machine contractors in order to improve the productivity of the tree handling, measurement and harvesting. The Epec products have very versatile properties. In spite of that, the equipment has been made so easy to operate that every user is able to utilize the properties completely. 1.3 EPEC 4W30 Display Controlling switches and preselections Programming wheel Cabin module Head module In harvester head Printer (extra equipment) HUB Four wires Bus and power distribution unit Instructions for use Epec 4W30 7 Epec 4W30 is a system designed for control of the grapple functions. There are separate control buttons for each grapple function (generally in the control levers of the machine) for control of each function separately. The tree can be fed either automatically or manually. Automatic feed is started by selecting the desired length via the preselection keyboard of the measuring equipment. Then the tree will automatically be fed to the selected length. Manual feed is carried out according to the sections Feed forward, Feed backward and Low speed in this manual. Epec 4W30 consists of three modules (display module, cabin module and grapple module), bus distribution unit, preselection keyboard (PS), programming wheel and control keys. The modules are interconnected with a CAN bus. CAN bus (Controller Area Network) is fast data transmission bus and it has high error immunity. The preselection keyboard is either integrated into the levers or installed very close to the control levers of the machine. The preselection keyboard is used for selection of the product to be made (tree species, wood type, length, tolerance and top diameter limit). In order to achieve blameless operation it is important to read the instructions for use carefully and to understand the meaning of the different settings before starting to use the equipment. The length and diameter must also be calibrated and all settings must be checked by setting a reasonable value (if necessary) for each of them. When the diameter is mentioned in this manual, it is supposed that a diameter sensor is in use. If the diameter is not in use, the diameter limits will not influence feeding to the preselected length. NOTE! Prefer not to switch the measuring equipment on until the machine is running, since there can often occur disturbances in the electric system of the forest machine in connection with start-up. Instructions for use Epec 4W Expressions Harvester: Multi-function head (grapple): Preselections: Preselection key: Automatic feed: Control keys: Programming wheel: Cursor: Display window: Upper menu: Display key: Enter key (green button): Machine for tree felling, delimbing and crosscutting. Harvester consists of base machine, crane and multi-function head. Multi-function head (grapple) is mounted onto a crane for tree felling, delimbing and crosscutting. This part includes saw, feed tracks, delimbing knives, gripping knives etc. Pre-programmed data (tree species, wood type, length, tolerance and top minimum) according to which the tree is crosscut into pieces of the desired lengths and diameters. Key used to make a certain preselection. Feeding to a certain length is started by pressing a preselection key. Keys used to control the mechanical actions of the grapple: for instance the sawing key. By rotating the programming wheel, the cursor is transferred in the display and adjustment values are changed. A rectangular frame that is moved in the display by means of the programming wheel. A graphical window forming a complete whole, used for display and adjustment of certain matters. Icons at the upper edge of the display. The cursor goes to the upper menu when pressing the Cancel key. When the cursor is around an icon and the Enter key is pressed, a new display window is opened. A square shaped frame appearing in the display of the display unit. The cursor is moved to this frame by rotating the programming wheel. There are two kinds of keys: Adjustment keys: pressing Enter when the frame is at the adjustment key activates the adjustment. After that, the adjustment value can be changed by rotating the programming wheel. Function keys: pressing Enter opens a new display window or activates a certain function. Key for acceptance: When the cursor is on a display key, adjustment or function is activated depending on the type of key. Instructions for use Epec 4W30 9 Cancel key (red button): Activation: Key for cancelling a started function: If an adjustment key is concerned, the adjustment is not accepted but the old value will still remain valid. The Cancel key is also used for moving the cursor between the upper menu and the display keys. When adjusting values, the adjustment is activated by pressing Enter. Then a shading appears around the control key in question. Instructions for use Epec 4W USER INTERFACE The user interface of the system consists of the control keys, the preselection keys, the programming wheel, the Enter and Cancel keys of the programming wheel, the graphical display and the symbols and texts displayed. Epec 4W System Enter key Cancel key EPEC Programming wheel Preselection keys In normal harvesting situations (when felling and crosscutting trees) the driver controls the system by means of the machine control and preselection keys. The settings of the system are changed by use of the programming wheel and the Enter and Cancel keys as well as the information seen in the graphical display. NOTE! Operator can select whether the measuring equipment uses the metric system (millimetres, centimetres, metres) or the imperial system (inches, feet). The data is displayed as units of the selected measurement system. The pictures in this manual are displayed in units of metric system. For detailed information, see chapter 7.39 Selection of measurement system. MAIN DISPLAY Upper menu Length Diameter Symbol of grapple closed Preselection data Info line. In this case it informs of shortcircuit or break in grapple output 2 Instructions for use Epec 4W30 11 The different display items can be selected by rotating the programming wheel and by pressing ENTER key or CANCEL key. The preselection data can be changed by pressing the preselection key in question to the bottom, then the frame jumps to the bottom line and the data to be changed can be selected with the programming wheel. Data can be changed, provided that the grapple is kept open during the change. Switching between the different display keys or adjusting the value of an active adjustment key is done with the programming wheel. The Enter key can be used for instance to open a new display window or to activate an adjustment key for adjustment. There is a shading around the active square, i.e. the lower edge and the right edge of the key are thicker than the other edges. The Cancel key is used for switching between the upper menu and the other display keys. Cancel is also used for removal of the activation of an active display key. The Cancel key can also be used for cancellation of a printout. In that case, the Cancel key must be pressed for appr. 2 seconds. Pressing the Cancel key for 4 seconds in the main display activates the service mode, where all the parameters can be adjusted. The text SERVICE is displayed on the bottom line of the display, when the service mode is activated.

The printout window has no display keys if there is no printer connected to the system Test Length calibration Calibration of the diameter pulse span Instructions for use Epec 4W30 13 PRESELECTIONS The preselections are pre-programmed data of the different types of pieces to be produced. The preselections consist of 5 different data: Tree species, Wood type, Length, Tolerance and Top diameter minimum. Tree species Wood type Active preselection Length Tolerance Top minimum Tree species is the botanical name of the tree (i.e. fir, pine). Wood type defines the use of the piece, for instance: if the pieces are intended for manufacture of paper, the wood type can be PULP, and if the pieces will be sawed to boards, the wood type can be LOG. Length is the desired length of the pieces to be made. Tolerance is the accepted deviation from the desired length. Top diameter is the minimum acceptable top diameter (given in millimetres). When pressing the preselection after the sawing, the harvester starts to feed the tree to the length of the preselection in question, observing the crosscutting tolerance and the desired top minimum diameter of the piece. If the diameter falls below the top minimum, the feed is interrupted at the diameter limit. The sawed piece is counted into the statistics of the preselection used. The number of running meters and the number of pieces produced for each preselection are added up. If diameter is used, the volumes are calculated, and if trunk counter is used, the trunk numbers are counted too (the trunk numbers are added always into that preselection, to which the first piece of the trunk is made). CONTROL KEYS OF THE GRAPPLE The control keys of the grapple are used to control the grapple functions. In order to ensure easy working, these keys are located either in the crane levers or very close to them. More detailed information is given in section 4. Grapple functions . Instructions for use Epec 4W FUNCTION 3.1 Initial Actions Before harvesting is started, the measuring equipment must be given information of the motion range of the grapple by opening the grapple with the key Grapple open and then closing it with the key Grapple closed. If pieces with other dimensions than those included in the system are wished to be produced, the preselection data must be changed. If harvesting is going to be started in a new working site or a new stand, the pieces of which must be counted separately, the job number must be changed. If the old data is wished to be saved, it has to be printed out. 3.2 Supposed Tree Harvesting Sequence The program of the measuring equipment supposes the trees to be felled in the following sequence: 1. After the equipment has been switched on, the grapple must first be used in opened and then in closed position, and the motion must be of the right extent (the pulse range must be sufficient, look at section 8.2 Pulse range calibration of diameter ), before the diameter is displayed (if diameter is used). Measuring equipment will not calculate the volume nor accept preselections, if the diameter is not displayed. Thus, measuring faults are avoided. Even if the diameter is not in use, the grapple must be opened and closed before the work is started. 2. To grip a standing tree the grapple had to be opened and lifted up. 3. After the tree is sawed the grapple had to be lowered in order to feed to the desired length. 4. The feed to the desired length starts when pressing the preselection and, by continuous feed (look at section 7.2 Feed method ), also after crosscut sawing (not after felling sawing). If manual feed is used during automatic feed, the automatic feed is interrupted. The automatic feed can be started again whenever wanted simply by pressing the preselection key. 5. When the tree has stopped at the desired length, the tree can be crosscutted and a new preselection can be made. The data of the produced piece is saved in the statistics of the active preselection. If trunk counter is in use, the trunk is added to that preselection, which is active when the first sawing is carried out. The length value is reset by sawing. Instructions for use Epec 4W Different Steps of Harvesting When starting to feed the tree to the selected length, the feeding is accelerated so that the outputs Feed forward 1 , Feed forward 2 , Feed forward 3 and Feed forward 4 are controlled on consecutively. After each output has been controlled on, there will pass a settable time delay (look at section 7.26 Feed delays ), before the next output is controlled on. Thus Feed forward 1 is controlled on time delay Feed forward 2 is controlled on time delay, etc. The measuring equipment selects, based on the distance to be fed, fast speed, low speed or search pulses. All the feed modes are used, if the distance left is more than twice the braking distance of the feed mode in question. If for example the braking distance for fast feed is 200 mm, the tree is fed with this feed mode, if the distance left until the desired length is reached is more than 400 mm, otherwise the tree is fed by low speed mode. The braking distance is the distance that the tree moves after the control of the feed valves has stopped. If there does not come enough pulses from the length sensors when feeding during the slip prevention time (feed jammed), the automatic feed is interrupted. When the slip prevention is zero, it is not in use (look at section 7.31 Slip prevention ). 3.4 Volume Calculation (if diameter is in use) The diameter of the piece is measured with intervals of 10 cm while feeding forward, and only diameters smaller than the previous one are registered for volume calculation. When the piece is crosscut, the volume is calculated based on the registered length and diameter values. The tree must be fed from the butt end towards the top. If the grapple has to be opened during the feed, the volume calculation of that piece will be interrupted. The handling of this piece must be started from the beginning by sawing a disk at the butt end. 3.5 Special Situations Handling of a Dropped Tree If the tree has dropped from the grapple, the volume calculation of the tree is interrupted. Then proceed as follows: 1. Open the grapple. 2. Take the butt end of the tree into the grapple. 3. Saw a disk at the butt end. 4. Feed normally. Instructions for use Epec 4W Handling of a Branched Tree 1. Saw the branches apart. 2. Open the grapple. 3. Take the butt end of one of the branches into the grapple. 4. Saw a disk at the butt end and feed normally. 5. Take the butt end of the other branch into the grapple. 6. Saw a disk at the butt end and feed normally Handling of a Tree Lying on the Ground 1. Open the grapple. 2. If trunk counter is in use, carry out felling sawing (lift the tilt up and carry out sawing) to increase the trunk number. 3. Take the butt end of the tree into the grapple. 4. Saw a disk at the butt end. 5. Feed normally. Instructions for use Epec 4W30 17 Instructions for use Epec 4W GRAPPLE FUNCTIONS 4.1 Knives Open When pressing the key Knives open , the delimbing knives are opened and remain open as long as the key is pressed. When the key is released, the delimbing knives are closed. If there are lock valves in the delimbing knives, then delimbing knives are closed when sawing, feeding forward or pressing the button Grapple closed is carried out. 4.2 Tracks Open When pressing the key Tracks open , the tracks are opened and remain open as long as the key is pressed. When the key is released, the tracks are closed. Also the back knife is opened and closed with the tracks, except when the back knife is opened by pressing the Back knife key. 4.3 Back Knife When the key Back knife is pressed, the back knife moves from one extreme position to another. When the back knife is open and the key is pressed, the back knife closes, and when the key is pressed once more, the back knife opens. If the back knife is opened with Back knife key, it will be closed only when pressing the Back knife key or the Grapple closed key. If the back knife is opened with the keys Tracks open or Grapple open , then the back knife will be closed also when the tracks are controlled to close. If the back knife is opened with the Back knife key and it has lock valves, then the back knife is closed when sawing or pressing the button Grapp
