1 GENERAL
1.1 Introduction
The intention of this manual is to make the reader acquainted with the
properties and use of the Epec 4W30 2L measuring equipment. 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.

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.

1.4 Expressions
Harvester: Machine for tree felling, delimbing and
crosscutting. Harvester consists of base
machine, crane and multi-function head.
Multi-function head (grapple): 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.
Preselections: 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.
Preselection key: Key used to make a certain preselection.
Automatic feed: Feeding to a certain length is started by
pressing a preselection key.
Control keys: Keys used to control the mechanical actions
of the grapple: for instance the sawing key.
Programming wheel: By rotating the programming wheel, the
cursor is transferred in the display and
adjustment values are changed.
Cursor: A rectangular frame that is moved in the
display by means of the programming wheel.
Display window: A graphical window forming a complete
whole, used for display and adjustment of
certain matters.
Upper menu: 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.
Display key: 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.
Enter key
(green button): Key for acceptance:
−When the cursor is on a display key,
adjustment or function is activated
depending on the type of key.

Cancel key
(red button): 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.
Activation: When adjusting values, the adjustment is
activated by pressing Enter. Then a shading
appears around the control key in question.
