HAZARD AREAS
Height of safety fence (according to standard: EN ISO 13857:2008):
• If the machine is raised with extended leg set, the height of the safety fence must be at least
300mm higher than the lower frame on the feed table. See gure below.
• As an alternative to higher safety fences all distances of at least 850 mm can be raised to a
minimum of 1400mm.
• Minimum recommended distance from safety fence to conveyor is 600 mm, safety fence
towards the conveyor is always to be a minimum of 2000mm high.

INSTALLATION
MaxiFeeder and MaxiMag are exible machines that can be designed according to your
wishes and needs. It can be delivered as MaxiMag with only feedtable/magazine or
MaxiFeeder with cutting device for cutting and processing of forage. The system can be
delivered with up to 5 mid-sections of 2 meters each, for a total length of 14,5 meters. The
shortest unit, consists of only back- and front-section will have a total length of 4,5 meters.
Mid-sections are bolted together with splicing plates, side supports, side walls and adjusted
chain.
OBS! Control the elements are placed edge to edge without any overlap.
Figure 8: MaxiFeeder with cutting device and
two mid-sections.
Figure 7: MaxiMag with two mid-sections.
STANDARD LEG SET
Standard leg-sets on MaxiFeeder and
MaxiMag if there is no other spesications.
This leg set can be combined with a
conveyor. Lifts the machine 600 mm from
the ground.
Slide the leg into the bracket on the side of
MaxiFeeder or MaxiMag. Fasten with bolts,
nuts and support rods as shown on gure 9.
Load cells are assembled as described on
next page.

INSTALLATION
STAN
The stand is assembled to the frame of the machine. The stand has lugs for assembling
supporting struts and must therefore be placed inwards toward the underside of the
machine.
The leg on the stand is prepared for adaption on site and can be cut to the required length.
To fasten the oor fastener a hole is drilled in the leg. Use the hole in the oor fastener
for steering during drilling. Bolt and counter nut are assembled in the hole to fasten the
installation. See gure below.
Figure 10:
Stand fastened to the frame.
Fastening the stand in the frame is done
with two throughout brackets which is
fastened to the stand. The stand is secured
with a supporting strut between the frame
and the leg.
The oor fastener is fastened to the
foundation with bolts.
Lug
To adapt the length of the stand cut the
legs to the required length. Floor fastener
is placed in the bottom of the stand (after
adjustment of length). Drill hole and lock the
oor fastener with bolt and counter nut. See
picture 9.

drilled in the frame.
In the back of the machine the bracket is
placed as shown on gure 11.

To adjust angle: loosen bolts beside the
fastener for the stand.
The fastener is twisted into wanted position
and bolts fastened to lock the position.

INSTALLATION INSTALLATION

LOAD CELL
MaxiFeeder with cutting device has a load cell
installed in each leg to measure the forage amount
which goes through the machine.
The load cells are placed on a ball to remove side
circuits. These balls are placed after the legs are
assembled. After installation calibrate load cells in
the setup menu with empty chamber.
See page 38 for fullling information about
calibrating load cells.
1. Place the machine in position. Load cells are delivered balanced
without ball to prevent damage on the load cells during
transportation.
2. Make sure the machine rest on the assembling jigs cone, to prevent
side circuits on the load cells. Fasten the base to the fundament.
3. Place ball in the groove on the base.
4. Fasten bolt to the machine lifts a couple of millimetres and thereby
rests on the ball. Make sure the ball is placed correctly between the
base and bolt.

CONNECTING
CONTROL CABINET
The control cabinet is complete and assembled from the factory. The placing of the control
cabinet is spesied when ordering.
Connecting:
• Power supply for control cabinet
• Startup signal from superior control/software
Signal for external startup of MaxiMag on input 19+20.
CONNECTING MAXIFEEDER AND TOPFEEDER
To control MaxiFeeder via TopFeeder use following setup:
Signal on input 11 Startup machine and running knifedrum
Signal on input 12 Pause mode canselled, conveyor belt can start
MaxiFeeder receeive startup signal when TopFeeder starts on input 11.
Machine starts with acoustic signal before startup. Knife drum runns.
When the machine receive signal on input 12 conveyor belt starts, feeding will thereby start.
When signal on input 12 ceases, the machine will go into pause mode where only kutting
device run, but forage will not be drawn to the drums.
This function is useful in combination with for instance TopFeeder where it is desirable to
pause the feeding while replacing the plow between the dierent groups, without stopping
the machine completely.
The signal can in sometimes be permanently xed to always feed when signal 11 is activated.
MAXIFEEDER OG MAXIMAG IS DELIVERED IN 230V OR 400V
MaxiFeeder use a control cabinet with more advanced software while MaxiMag has a control
cabinet with a more
Two motors for conveyor belt is used when there are three or more midsections.
