INTRODUCTION
This manual contains important information concerning your Rutland Furlmatic
910-3 Windcharger and its installation and operation.
It is strongly recommended that you read this manual and familiarise yourself
with its contents before installing and operating the Windcharger system.
The Rutland Furlmatic 910-3 Windcharger is designed to provide a direct
current (DC) power supply via a battery bank for 12/24V equipment, lighting,
etc. It is intended for professional and leisure applications which require
battery charging at off-grid locations.
WARNING!
• When turning, the Windcharger is capable of generating voltages in excess of
the nominal voltage,therefore the Windcharger should not be allowed to
rotate without connection to the battery. Caution must be exercised at all
times to avoid electric shock.
• No attempt to repair the system should be made until the wind generator is
restrained from turning.
• The Windcharger is fitted with ceramic magnets which can be damaged by
heavy handling. The main generator assembly should be treated with care
during transit and assembly.
• It is essential to observe the correct polarity when connecting the
Windcharger and all other components into an electrical circuit. Reverse
connection will damage the Windcharger and incorrect installation will
invalidate the warranty.
• The fuse supplied must be fitted to protect the system. (If the Wind generator
is used in conjunction with the RWS200 Charge Controller, this fuse is
already incorporated within the controller).
• If in doubt, refer to your dealer, a competent electrical engineer or the
manufacturer.

SITING THE WINDCHARGER
General Considerations
The location and height of the mounting pole or tower for your wind turbine
will be the major factor in the overall performance of your system.
The smooth flow of wind over land and water is often interrupted by a multitude
of obstructions causing wind sheer and turbulence.
Wind sheer describes the interference between the fast moving upper air and
the slow moving air close to the ground and the resulting decrease in average
wind speed as one gets closer to the ground.
Turbulence is caused by the wind passing over obstructions such as moored
boats, trees and buildings. Both wind sheer and turbulence diminish with
height and can be overcome simply by putting the machine sufficiently high
above them.
It is therefore essential that the wind generator should be located in an area as
free as possible from disturbed wind flow. Bear in mind that downwind
obstructions can be as detrimental to performance as upwind obstructions
(Fig.1).

PRINCIPLE OF OPERATION
Generator
The 3 phase ac generator is driven directly by the aerofoil blades, rotating
permanent magnets around the fixed stator winding. The variable
frequency alternating current is rectified within the generator housing, and
the resulting rectified current is transmitted via the sliprings and brushes at
the yaw axis to the output cable.
Winding Over-Temperature Protection
The generator stator winding incorporates embedded thermal protection to
protect the winding from damage due to over temperature during extreme
winds. On reaching the thermal protection limit, the device will reduce
generator output current to allow the winding to cool, whereupon normal
performance will be resumed. If the thermal protection is active, the
turbine may reduce to a slow rotational speed with a corresponding
reduction in charge current, this is normal.
Furling Tail System
The tail assembly is designed to direct the turbine into the main direction
of the wind at windspeeds up to approx 15m/s. Above this the automatic
“furling” mechanism is activated to turn the generator at an angle to the
wind to protect the turbine, generator and supporting structure from severe
electrical and mechanical loads due to high winds. When the wind speed
subsides, the tail assembly will automatically return the turbine to normal
operation. In prolonged gusty & turbulent conditions, the system may be
seen to repeat this cycle many times. Power will be reduced during
furling. For effective operation of the furling system the machine must be
sited to ensure it is as free as possible from turbulence and in a stable
upright position.
5
TOWER CONSTRUCTION
The Furlmatic 910-3 is designed to fit inside an aluminium, stainless or
steel tube with an internal diameter of 41mm with a minimum wall
thickness of 5mm.
A suitable mounting pole can be erected using a 6.5 metre (21 feet)
galvanised (medium) tube. The tube must be supported by a minimum of
four guy lines.
The attachment points for the guy lines to the tower should be securely
fixed to the tower.
•
•
•
•
The guy wires should be a minimum of 4mm in diameter.
The shackles should be a minimum of 5mm in diameter.
Rigging screws should be a minimum of 5mm in diameter.
All items should be galvanised or stainless steel for protection against
corrosion.
• Where guy lines are looped, the loop must incorporate a thimble and be
fitted with a minimum of three rope grips.
• All ground fixings must be made suitable according to the terrain.

ASSEMBLY AND INSTALLATION OF THE WINDCHARGER
Blade Assembly (Fig.4)
1. Place the generator assembly on a flat surface hub-side down.
2. Position blade as shown. The blades will only fit one way round.
Insert the protrusion at the trailing edge of the blade root fixing first into
socket to align with the corresponding recess in the blade socket. The
blade can then be easily inserted with a lever action. Gentle assistance
with a soft faced mallet may be required.
3. Four screws are required for each blade. First secure each blade with
two of the special self-tapping screws provided.
4. Fit the remaining 2 blade screws from the front of the generator hub.
5. Check tightness of all screws. (Do not over-tighten).

BATTERIES
Leisure/Deep Cycle batteries are specifically designed for good
performance in terms of charge/discharge cycles. Batteries are the most
important part of your battery charging system and should be sized
according to your load requirements and provide at least 3 days reserve
capacity. This will reduce cycling, prolong the life of the battery and
ensure system reliability during periods of low wind
Permanent connections should always be made to the battery terminals.
Never use crocodile clips or similar devices. Battery terminals should be
well greased with petroleum jelly or similar.
We strongly recommend the SR200 or RWS200 is fitted to prevent battery
overcharging in strong winds and is essential with gel/sealed batteries.
Batteries may be linked as follows:
• In parallel to increase amp hours (Fig.6).
• In series to increase voltage (Fig.7).

SPECIFICATION AND PERFORMANCE
INSPECTION AND MAINTENANCE
The Rutland Furlmatic 910-3 requires no scheduled maintenance but an annual
inspection should be carried out to monitor the general condition of the system.
• Before inspection, the turbine should either be lowered to the ground or tied to
prevent the generator from turning. To stop the generator from turning follow
one of the procedures below:
1) Lower the windcharger on its tower to the ground, coming to rest on a structure
that will prevent the windcharger from striking the ground. Take care that all
persons are clear of the area. The turbine will eventually slow down. Tie a
blade to the mounting pole to prevent it from rotating.
2) If the tail boom is safely accessible, using the tail boom, rotate the generator out
of the wind, the turbine will eventually slow down. Tie a blade to the mounting
pole to prevent it from rotating.
• Whilst the generator is stationary, the following routine checks should be
performed:
1) Check the blade screws for tightness.
2) Check all other nuts, bolts and screws for tightness.
3) Check the yaw axis for free rotation.
4) Check the tail fin moves freely.
5) Check tower assembly for condition.
6) Check the tension of the guy wires if applicable. The tension of guy wires
should be checked frequently during the first year.
7) The unit can be wiped with a mild detergent and rinsed with water to remove
dirt and debris.

TROUBLESHOOTING
In the unlikely event that your Rutland Furlmatic 910-3 should develop a defect,
the turbine should either be lowered to the ground or tied to prevent the blades
from turning before the following inspection is carried out.
1. Read the Electrical Connection (page 10) and Up and Running (page 13) and be
satisfied that the system complies.
2. If your Furlmatic 910-3 fails to turn or produces low output, check the
following:
• Is there sufficient wind? The Furlmatic 910-3 needs 5mph wind speed to start
charging. At wind speeds below this, the turbine may be turning but will
produce no output. The wind speed across the turbine blades may be greatly
reduced in a built-up area or where surrounded by trees compared with
windspeeds quoted in weather reports.
• Is the battery in good condition? Check the voltage and electrolyte level of
each battery.
• Check electrical continuity throughout the system, especially corrosion and
poor connections in cable joins and connector blocks.
• Check the brushes and slipring for wear or damage. To inspect the brushes,
remove the cover plate on the side of the windshaft housing (white box) by
removing the four fixing screws. Inspect the brushes and slipring positioned
immediately above the yaw axis. Remove any black deposits from slipring with
emery paper.
• Check hub for free rotation with generator disconnected from battery. If
the hub does not rotate freely, check for a possible short circuit in the wiring. If
no wiring fault is found refer to your dealer or manufacturer.
• Remove the SR200/RWS200 from the charging circuit and connect the
Windcharger directly to the battery via an ammeter. Raise the wind generator to
it’s running position. If no charge current is measured and there is sufficient
wind, contact your dealer or manufacturer. If charge current is normal the
battery is fully charged or regulator is faulty.
Remember to always stop the wind generator from turning before making
any connections or disconnection’s.
If in doubt, refer to your dealer or manufacturer, quoting wind generator
type and serial number.
A comprehensive fault finding manual is available from your dealer or the
manufacturer : Document No SM2-127.
