FEEDING SYSTEM MASTER CHAIN®
Preface
Thank you for selecting Egebjerg’s MASTER Chainmechanic feeding system.
The feeding system comprises a number of quality products that, combined correctly, gives you a system
characterised by great operating efficiency and a long working life. To ensure the greatest possible benefit of your
new feeding system in the years to come, please read this manual and follow the instructions given carefully.
Should you have any questions once you have read the manual, place contact one of our service employees on
tel.: [phone], fax: [phone] or on e-mail: [email protected].
Introduction
Egebjerg Master Chainis a modern dry feed dispenser system developed to transport animal meal or pelleted
feed with a diameter of up to 5 mm and a length of 10 mm from a silo to a number of feeding locations in the pig
barn.
The feed is transported in a galvanised steel piping system. The feed is transported via a chain or wire fitted with
cast plastic carriers that drives the feed to the feeding locations.
A computer-controlled drive unit drives the chain or wire. Once all feeding locations are full, a sensor switch
signals to the computer that the feeding system has been filled and must be stopped. The sensor switch is placed
after the last feeding location.
The drive unit is equipped with mechanical and electronic fuses against overload.
The loading system is placed below the silo, and doses the feed evenly and precisely into the piping system. Thus,
the loading hopper is indirectly decisive for the operating efficiency of the system and the working life of the feed
wire or feed chain.

Safety
-Switch off power to the system during service or inspection.
-Lock the main switch on the control unit.
It is dangerous to service or inspect the system without cutting off the power first. The system may
start automatically or another person may start it without knowing that the system is being serviced.
Therefore, do not dismantle the system or dismount screening, lids and covers without cutting off and
locking the main switch.
Never place objects or parts of the body under a feed outlet or other openings to clean away feed
remains or similar, without cutting off power and locking the system first. There is a great risk of being
injured if the system starts up by mistake.
Mounting and repairs of electric installations only to be performed by a trained electrician.

FEEDING SYSTEM MASTER CHAIN®
Planning the location of the feeding system
Before initiating installation of the feeding system it is essential to plan in detail the layout through the
pig barn, including the location of the individual components.
The longest working life is obtained by installing the feeding system with the lowest possible amount of
bends.
Please consider the following when planning the piping layout:
• Floor-to-ceiling height, windows, doors and gates that it must be possible to open.
• Steel rafters or other objects protruding from the walls or hanging down from the ceiling.
• Ventilating plants, posts or other piping that the feeding system passes.
• The possibility of suspending, supporting or in other ways fixing the feed pipe.
Installation height
Normally, the feed pipe should be installed at a height of 2.2-2.4 metres.
Please note that it must be possible for people working in the pig barn to open and close the shutters
in the feed outlets on the feed pipe. (In pig barns using Egebjerg’s KS dispensers, the feed pipe is
installed at a height of 2 metres.)
Feeding systems using plastic feed dispensers must have free space of 15 centimetres from the
underside of the feed pipe to ceiling, rafter or similar to make room for installation of wire and fittings
for central opening.

Bends
Where the feed mechanism changes to another level, the feed must be lifted via piping at a 45-degree slope, if
possible. This reduces the risk of segregation while at the same time causing minimum strain on the system. The
return pipe, on the other hand, may be lead down vertically.
Z piping and two bends, assembled at a right angle, are to be avoided wherever possible. This type of
installation causes the transport wire to twist and applies unnecessary strain on the system. If this
type of wiring is unavoidable, the distance between the bends must be a minimum of 2 metres.
Loading hopper
Place the loading hopper below the feed silo.

Drive unit
The optimum location of the drive unit is between the last feed outlet and the loading hopper. See
rotating direction on the illustration.
The drive unit may be installed:
-directly on the floor
-4-20 cm above the floor on adjustable legs
-on wall-mounted shelf brackets
Egebjerg’s drive unit has been designed to allow feed to pass through. Consequently, the drive unit
may be placed at the middle of the feeding system if other locations are not possible. This type of
installation, however, increases the risk of feed segregation, and should therefore be avoided.
The drive unit works best when there is a long piece of straight piping before the drive unit inlet.
In chain systems there must be a straight piece of piping measuring at least 3 metres from the drive
unit inlet to the bend before it.
Sensor switch
Place the sensor switch after the last feed outlet. Place the sensor a minimum of 1.5 metres from the
nearest feed bend.

Assembly
Loading hopper
Place the loading hopper below the silo. The station may be attached directly to the silo using bolts or attached via
a funnel installed on top of the loading hopper.
The loading hopper is supplied with or without gate. If the silo does not have a gate we recommend you select a
loading hopper with a gate.
If you use a funnel and your silo has a gate, the top edge of the funnel must be lower than the silo gate, allowing
it to open freely.
In outdoor installations we recommend the loading hopper to be protected with a cover to prevent water
percolation.
Attach the loading hopper directly to the floor using coach screws or mount on adjupig barn legs to adapt the
height to the silo.
Mount the inspection pipe after the outlet pipe on the loading hopper using a splicing sleeve. Place the inspection
pipe so that the oblong hole is horizontal, and covered by the slotted plastic tube. Attach the plastic tube to the
inspection pipe using two clamps.
The inspection pipe allows the user to see how full the feed pipe is, thus checking the adjustment of the loading
hopper.
Adjustment
The loading hopper is fitted with a motor that drives a horizontally rotating arm via an axle. The rotation of the
arm causes continuous administering of feed to the feeding system to occur, thus preventing overload and
blocking. The feed quantity may be adjusted using a turnable dosing gate.
Considering the load and operating reliability of the system, we recommend the feed quantity to be set so that the
feed pipe is approximately half full. The feed pipe must never be more than two thirds full.

Drive unit
The optimum location of the drive unit is between the last feed outlet and the loading hopper. See rotating
direction on the illustration.
The drive unit may be installed on the floor, raised above the floor on adjustable legs (4-20 cm), or on the wall
using shelf brackets.
Feed pipes
The feed pipes are galvanised on the inside and outside. Inside the pipes is a little welding seam that must face
upwards when installing the pipes. This prevents unnecessary wear of the carriers on the feed wire or feed chain.
If required, shorten the pipes using a hacksaw or an angle grinder. Saw the pipes at a right angle, allowing for a
tight connection in the splicing sleeves. Grind the pipes on the inside and the outside, and remove any chips from
the pipes before installation.
The feed pipes must be supported every 3 metres, and attach to the ceiling, wall or a post using fittings. The
pipes must be fixed tightly so that it is not possible move them horizontally or vertically. It is important not to
force or bend the feed pipes around obstacles. Use a guide to check whether the piping is straight. If the feed
pipes are not mounted correctly, the carriers are subjected to unnecessary wear on the inside of the pipes,
causing damage to both pipes and carriers.
If the feed pipes are lead from a warm pig barn outdoors or through a non-insulated room, we recommend the
pipes to be isolated through the cold area to prevent the feed from coating inside the pipes as a result of
condensation.

Splicing sleeves
Mount splicing sleeves with the screws pointing upwards to prevent feed loss. Where joints are made
outdoors, the splicing sleeve must be turned, placing the screws on the side of the tube to avoid water
percolation. If the joints are required to be completely tight, tighten with silicone.
Bends
Feed bends are mounted so that the cover with the wing screw points downward, and the direction indication on
the inner wheel is in accordance with the transport direction of the feed.(60 mm inner wheel does not have a
predetermined rotating direction). If the rotating direction on the corner wheel is incorrect, too much resistance
will build up in the system over time, and the system may subsequently break down.

Rotating direction
When mounting the feed pipes, make sure to push them all the way to the stop in the corners.
Feed outlet
When the feed system has been assembled, mark up for outlet holes where feed outlets or feed dispensers are to
be placed. Drill the outlet holes in the feed pipe using a tapered drill. See the size in the table.
Deburr the holes in the feed pipe on the inside and outside.
Mount the top cap of the feed outlet on top of the feed pipe, then tighten the feed outlet using a Parker’s
screwdriver.
Note!
Always tighten using a hand-held screwdriver, allowing the gate to move freely back and forth.
Do NOT use a clamping device or drilling machine
