The generator is designed to be mounted onto a 2i2-inchh50.8 mm) diameter steel pipe. The pipe should have a minimum wall thickness of .156 inches (4 mm). Supplied with the generator is a mounting flange. This must be welded square to the top of the mast. It should be welded in three positions on the underside, between the mounting bolt holes. The top face of the flange should be welded all round. After welding, sand flat and paint. The generator is attached to the mast flange by the 3 M8 X 30 Hexbolts and Nyloc nuts.
ATH: THE GENERATORS’ PIVOT SHAFT IS CLAMPED TO THE ADAPTOR BY A SPECIAL LOCKING BOLT AND FACTORY TIGHTENED TO THE CORRECT TORQUE.IF, FOR ANY REASON, THIS IS REMOVED, A NEW M8 NYLOC NUT MUST BE USED AND TIGHTENED TO A TORQUE OF 450 POUND-INCHES.
The pipe should be firmly erected to prevent excessive sway in strong winds, either by fitting stays or by securing it to a rigid post or wall. To prevent accidents, it is important that the generator is mounted with at least 9 Feet (3 Metres) clearance between the blades and the ground. To gain maximum output, the generator should be sited so that there are as few obstacles as possible to the prevailing wind. The mast must BEIS PERFECTLY UPRIGHT AND RIGID FOR THE AeroGen-F to operate AND TRACK THE WIND CORRECTLY AT ALL WIND SPEEDS.

SAMSETNING

SAMSETNING VIÐVIFTABLÉ
Assemble the fan using the M6 X 25 screws, M6 Nyloc Nuts, and M6 Washers. The best way to assemble the fan is to lay the Inner Fan Hub on a flat surface, blade sockets upwards, and then insert the 6 blades concave side (hollow side) upwards. See Fig. 1. Place the Outer Fan Hub on top, locating the blades in the sockets. Insert the 6 off M6 screws, washers, and nuts, and at this stage, only tighten the nuts sufficiently to lightly grip the blades. See Fig. 2. Turn each blade until the indicator mark on the blade and hub align as shown in Fig. 3. Note how the right-hand side of the blade indicator mark is set to align with the indicator mark on the outer hub. This sets the blade tip angle to 10 degrees. Then, finally, fully tighten the nuts and fit the M6 plastic nut covers. We recommend that the fan assembly be fitted after the generator is mounted.

SAMSETNING HALDA
Attach the tailfin onto the tail tube using the M6 x 35 long bolts, washers, and M6 Nyloc nuts.

RAFGIGN
Aero6gen-F output wire colour Code – The Red output wire is POSITIVE (..+) The Black output wire is NEGATIVE (-).. Wire Rating – The output wires of the Aero6gen-F will require extending. Electrical systems lose energy from the resistance of the wire size used. The larger the wire size, ze the smaller the l; ss, however, larger cross-sectional area wire can be costly and in some cases more difficult to source. The following table shows recommended wire sizes; they are based on a 3% and 5% energy loss at an average wind speed of 20 knots. It is recommended that a minimum wire size of 4.0 sq mm be used.

If the Aero6gen-F is connected directly to the battery terminals, we recommend a 30 Amp öryggi fyrir 12V gerðir og 15 Amp fuse fo24V4v Models is fitted in the red (positive) wire from the generator to the battery, so that if a dead short occurred, it would prevent serious damage to the wiring and the generator. The RED OUTPUT WIRE output is connected to the POSITIVE + terminal of the battery. The BLACK OUTPUT WIRE to the NEGATIVE terminal of the battery.

VOLTAGE REGLUGERÐ
The output wires of the Aero6gen-F can be connected directly to the terminals of the battery that requires charging; however, if the terminal voltage of the battery is not continually monitored for overvoltage (14.2v for 12v batteries nd 28.4v for 24v batteries), the battery can be seriously damaged. Fitting an LVM voltage regulator will protect the battery from becoming overcharged. You may well have chosen a voltage regulator when purchasing the Aero6gen-F, but we would recommend you read the section below, SELECTING THE CORRECT LVM VOLTAGE REGULATOR, to make sure you have purchased the correct unit. You may also consider installing an ammeter, voltmeter, or an ampere meter – all are available from LVM, part number as follows –
(LVM66) 0 –5A Ammeter, (LVM67) 0 –20A Ammeter, (LVM69) 0-15v dc Voltmeter (LVM200) Digital Amp Klukkutímamælir

AÐ VELJA RÉTT LVM RÚMMÁLTAGE Eftirlitsaðili
The output of the Aero6gen-F can be simply connected directly to the terminals of the battery that requires charging; however, if the terminal voltage of the battery is not continually monitored for overvoltage (14.2v for 12v batteries, 24v for 24v batteries), the battery can be seriously damaged. Fitting an LVM voltage regulator will protect the battery from becoming overcharged.

HITABÚNAÐUR – This additional feature is available on all LVM regulators. If the battery is located in
a building where the ambient temperature is always around 20 deg.C, then standard regulators can be used. However, if you intend to locate a battery where temperatures may go down to freezing and perhaps rise to tropical temperatures, then you should install a regulator that is fitted with a temperature compensation circuit. This automatically allows the battery to be charged at a higher voltage þegar hitastigið lækkar og lægra rúmmáltage if the temperature increases.
Simply add (-T) after the LVM Product No. Ie. 4SB12 –T.

There are two types of regulators suitable for the Aero6gen-F.

1. Einn rafhlöðustýrir – LVM vörunúmer 4SB12, 4SB24 – Þessar einingar eru einfaldlega tengdar við rafhlöðutengi og ef rafhlaðan er með hærri spennutage reaches 14.2v (12v systems) or 28.4 (24v systems), the regulator diverts power to a high-wattage wire-wound dump resistor. This regulator should NOT be used if you have any other form of charging system connected to the battery, ie. Mains charger/ shore power, engine-driven alternator.
   Athugið: These regulators draw a continuous small standby current of around 10mA – 15mA.
2. Twin battery regulators – LVM product No. 4TB12, 4TB24, 6TB12, 6TB24 – These units are connected between the output of the Aero6gen-F and the battery terminals. They control the actual output voltage of Aero6gen-F by diverting power to a high-wattage wire-wound dump resistor when their output voltage reaches 14.2v (12v systems) or 28.4 (24v systems). They have two Schottky blocking diodes built into the regulator that enable them to monitor and control the charge to two batteries, totally independent of each other, therefore making it ideal for separate charging of engine starting and domestic batteries. The battery with the lowest terminal voltage will be charged first, then gradually, when both batteries become fully charged, the Aero6gen-F output is automatically diverted to the dump resistor. This does two things: it stops the battery from overcharging and keeps the generator always on load.
   Athugið: These regulators draw NO standby current from the battery.

Also available from LVM are Diode Units – LVM product No. 4DU, 6DU
The 4DU, when combined with a 2TB or 4TB regulator, enables one additional battery to be charged. The 6, when combined with a 4TB regulator, enables two additional batteries to be charged. The Aero6gen-F and a Solargen module’s output may often be combined; the table below shows the recommended regulator for various systems.
Athugið: Two batteries wired in parallel are classed as one independent battery. Having selected the recommended regulator model from the table, simply add the voltage required, ed ie. 4TB12 for a 12v system or 4TB24 for a 24v system. If you cannot find your particular system or application within the table or require full wiring diagrams, please check our websíða www.lvm-ltd.com or call our sales office, which will email, fax, or post you copies.

Whilst initially installing the generator or carrying out future maintenance, it is important that the fan assembly is stationary.

1. The Aero6gen-F output cables are stripped and ready to insert into one end of a butt sealed splice. This type of connector is suitable for 2.5 sq. mm cables. Strip one end of your output cable 5 – 6 mm, observing polarity. Insert them into the other end of the butt sealed splices and, using a crimping tool, crimp them. A hot air gun can seal the joint, or carefully use a cigarette lighter with the naked flame well away from the actual plastic, just use the heat. This will make the plastic ends contract and grip the cable, giving a waterproof joint. If you decide to use some other type of connector, which can accommodate a larger cable size, it must be rated at 30 Amps.
2. Thread the output cable carefully through the centre of your mounting tube. If the bottom of the tube is not accessible, a hole must be drilled to enable the cable to be brought out. Be sure to leave enough slack in the cable so that, if necessary, the generator can be removed.
3. Locate the generator on top of your mast mounting flange, and insert the 3 x M8 retaining bolt. Fully tighten the M8 Nyloc nuts.
4. Fitting the fan blade assembly onto the main shaft of the generator. Grease the an hub bore, then fit the fan assembly onto the generator main shaft, aligning the M8 clearance hole in the fan hub boss with the M8 tapped hole in the main shaft. Fit the M8 spring washer under the head of the M8 x 25 Socket Cap Screw. Insert the bolt through the M8 clearance hole in the outer fan hub boss and fully tighten it into the main shaft using the Allen key supplied (best to increase the leverage on the Allen key by fitting a tube or something similar to make sure it is fully tightened). See Fig. 4. Push the safety circlip into the shaft groove as shown in Fig. 5, then finally push fully into the gro. The black hub cover is then pushed onto the hub boss.
5. Fully grease the tail pivot shaft on the generator and the bearings in the tail tube assembly, fit the tail fin assembly onto the tail pivot, grease the top face of the bronze bearing, fit the retaining bolt and washer, tighten fully, and fit the plastic nut cover. See Fig. 6
6. The output wires are then connected to the battery. The RED WIRE is connected to the POSITIVE + terminal and the BLACK WIRE to the NEGATIVE – terminal. We recommend a 30 Amp öryggi fyrir 12V gerðir og 15 Amp fuse for 224V models be fitted in the red positive. Cable from the generator to the battery, so that if a dead short occurred, it would prevent serious damage to the wiring and the generator. Note: Do NOT reverse the connections from the generator to the battery (ie, Generator Positive to battery Negative and generator Negative to battery Positive). Doing this will damage the rectifier and void your warranty.

VIÐHALD

The Aero6gen-F is designed to operate for long periods without needing any maintenance. The life of the generator and its performance will be enhanced if periodic inspection is carried out. For personal safety reasons, before carrying out any inspection, make sure you stop the generator from rotating. The following should be checked every 6 months.

• Athugið hvort blöðin séu skemmd og skiptið þeim út ef þörf krefur. Notið ekki rafstöðina með skemmdum eða ójafnvægðum blöðum. Það mun valda óþarfa sliti og hugsanlega skemmdum á aðallegum.
• Check the fan hub and tail pivot assembly for tightness. (grease tail pivot)
• Athugið hvort festingarmillistykkið og festingarkerfið séu þétt.
• Athugið hvort allar ytri rafmagnstengingar séu þéttar eða tærðar.
• Wash down the generator with fresh, clean water to remove debris that can build up.
• After several years of use, the carbon brushes that collect current from the slip rings may require replacement.

Carbon brushes Pt. No. BRUSHES 781 are available, complete with full instructions. If you experience a problem with your Aero6gen-F, contact LVM to determine the nature of the problem. LVM will send you replacement parts and instructions needed to repair the generator. If the generator is returned for repair/service, you will be notified of the cost for carrying out the work and will incur the transport costs.

AÐ STÖÐVA AERO6GEN-F
Electrical stopping
A 20A double-pole on/off/on switch can be fitted as shown in the wiring diagram opposite. This will short-circuit the Aero6gen-F’s output, and the fan assembly will stop or slow down considerably, then the fan assembly can be tied off to the mast.
VIÐVÖRUN – THE BRAKE SWITCH SHOULD ONLY BE USED TO STOP/SLOW DOWN THE FAN ASSEMBLY BEFORE SECURING WITH A ROPE – IT SHOULD NOT BE USED AS A PERMANENT PARKING BRAKE

VILLALEIT

The AERO6GEN-F is designed to give many years of reliable service as it contains really only two moving parts and one electronic component; they are the permanent magnet rotor, the slipring brush assembly, and a rectifier. The only parts that can wear are: Main bearing ball races, pivot shaft ball races, and the carbon brushes, which make contact with the sliprings. For safety reasons, fan blades are designed to break off aarmorhahasaught in the fan.

EINFALT PRÓF
Einföld prófun til að sanna að úttaksrúmmál sé til staðartage from the generator can be carried out whilst the generator is in its working position. Disconnect the generator’s output cable from the battery or the voltage regulator if fitted. With the fan turning in the wind and the two output leads open circuit, allow the fan to build up speed, then touch the two output leads together (shorting them), the fan should noticeably slow down and act as a brake. If this does not happen, check that your extension wire connection from the actual generator’s output cables is not corroded or has become disconnected. If there is a fuse fitted in the output cable, check that it has not blown. The above test can also be carried out by turning the generator’s main shaft by hand (in any direction to check the braking action.
Athugið: Although the instruction sheets supplied with the generator warn you not to run the generator in an open circuit condition, the tests can be carried out safely at wind speeds of up to 20 knots. (The reason we do not recommend generators be left in an open circuit condition is that at very high wind speeds, the suppression capacitors’ maximum voltage gæti verið farið yfir og eyðilagt þau.

Ef ekkert binditage is present, check that your extension wire connection from the actual generator’s output cables is not corroded or has become disconnected. If there is a fuse fitted in the output cable, check that it has not blown. Check the output voltage again at the actual output cable. If there is still no voltage output, go to the instructions and tests listed under the heading NO OUTPUT.

MINNKUR AFKÖST
Check that blades are set at the correct angle, and the concave side (hollow side) of the blade faces the wind. The main shaft of the generator should turn freely; however, there will always be a slight resistance, which is called the cogging effect. To check the starting torque/cogging effect of the generator is correct Sellotape on 4 – 5 pound coins. (40 – 50 grams) on the tip of a blade. Set this blade by turning the fan till it is horizontal, let go of the blade, and the fan should just start to turn. If the fan turns on ok as described above, then follow the instructions under the heading NO OUTPUT, with particular attention to the rectifier test. If the fan did not turn as described in the test above, follow the instructions and tests listed under headings KNOCKING/SCRAPING SOUND ONCE PER REVOLUTION, MECHANICAL NOISE, and NO OUTPUT.

ENGIN ÚTTAKA
Remove the generator from its mounting, taking off the tailfin and fan assembly. Remove the rear cover (6 ocrews) and hinge back the cover. A component called a rectifier that converts the 3 Phase A/C output voltage statorsins í jafnstraumsrúmmáltage is mounted on the inside of the cover. (Note: later models have also suppression capacitors soldered to the rectifier.) You will note that the rectifier has 5 terminals, 2 of which are marked + and-, the remaining 3 unmarked terminals are connected to the 3 output wires from the stator (3-phasea/c ~). Disconnect these 3 push fit connectors from the rectifier, then using a multimeter set on resistance measurement (ohms), check the resistance in turn of the 3 output wires (in pairs) from the stator. They should read 0.9 ohms 12v model, 3.5 ohms 24v model. When replacing the push-fit connectors to the rectifier after the test, there is no need to remember which order or terminal they came from, as they can fit on any of the 3 unmarked terminals.

ATHUGAÐU ÚTGANGSSTÆÐI LOFTRÆSTINGARTAGE AF STATÓR
Set the multimeter to read A/C volts, attach test leads to the 3 off stator output wires (in pairs), then turn the main shaft of the generator by hand (any direction) small voltage should be indicated on the multimeter. Check the stator and suppression capacitors; they should not look burnt or overheated. Check the tightness of stator retaining screws. If at any time the generator’s output leads have ever been connected to battery terminals the wrong way round, or the generator has been struck by lightning, t thenen the rectifier may have been damaged.

If in doubt about the condition of the rectifier, replace it with a new one.

ATHUGAÐU RENNIHRINGA OG BURSTA
Remove the brush cover assembly (4 screws). Hinge back brush cover assembly, leaving the red and black wires attached. Check the condition of the sliprings and clean them if necessary. Check that the spring-loaded carbon brushes are clean and are free to move in the brush holder. Set a multimeter to continuity check (buzz test). Check there is continuity between the top carbon brush and the positive + terminal of the rectifier, then check there is continuity between the bottom carbon brush and the negative terminal of the rectifier. Check that there is continuity between the top slip ring and the red output cable of the generator. Then check that there is continuity between the blackout output cable of the generator. If no continuity is found on one or both output leads, check the soldered joint on the slipring. Resolder if necessary. Set the multimeter to read 0-15 volts DC. Connect the test leads of the multimeter to the brushes, the top brush is (Positive +),, bottom brush is (Negative -). Turn the generator main shaft by hand in any direction. If a voltage is present, then refit the brush cover using a new gasket. Attach the test leads of the multimeter to the output wires of the generator, then turn the main shaft again to check that a voltage er til staðar.

BANKA-/SKRAPAHLJÓÐ EINU SINNI Í HVERJUM SNÚNINGI
Whilst the generator is in its working position, check that the M8 allen screw, which retains the fan assembly to the main shaft, is fully tightened. Also, check the tightness of all other fasteners on the fan assembly, mounting adaptor, and tailfin. Check that the safety circl,,ip which is fitted on the end of the main shaft, in front of the fan assembly, is not loose and making a noise. Remove the rear cover and check the condition of the rotor; it may be rubbing on the stator. The inner main bearing could be worn; check for axial and radial movement. Check the tightness of the 4off M5 stator retaining screws; this can cause a noise if slightly loose.

VÉLFRÆÐUR hávaði
If the generator did not make the noise when first installed, but has very gradually developed a noise. Check the following –

1. Grease main bearings (recommended grease Castrol Spheerol L-EP2 or equivalent)
2. If the generator has been operating for 3 years or more, it may be that the main bearings need replacing.
3. If the generator is only quite new, the main shaft may have worn where the bearing inner race is located on the shaft.
4. The stator assembly has worked loose.
5. The fan assembly locking bolt is not fully tightened
6. Generator mounting arrangement not fully tightened.

If the generator did not make the noise when first installed, but has very suddenly developed a noise. Check the following –

1. If the noise developed after the generator had been subjected to very high wind speeds during storms, it may be that the three-phase rectifier has been damaged..
2. If the generator is only quite new, the main shaft may have worn where the bearing inner race is located on the shaft. The bearing assembly has worked loose. The fan assembly locking bolt is not fully tightened.
3. Generator mounting arrangement not fully tightened.

CHECKING MAIN BEARINGS
Remove the fan and check axial and radial play in the main front bearing. Remove the rear cover and check the inner main bearing in the same manner. If a large amount of play is found, replace the main bearings. Follow instructions listed REPLACING MAIN BEARINGS. Whilst the rear cover is removed, check the tightness of the 4 off stator retaining scre.ws

ELECTRICAL VIBRATION NOISE
As described on page one, it is normal for the Aero6gen-F to produce a very slight magnetic cogging vibration when rotating, and an electrical vibration whilst charging. This noise will be greatly amplified if the Aero6gen-F is mounted against a wall of a building. Well-known methods that can reduce vibration noise are listed below.

1. Gúmmífestið eins margar festingar og mögulegt er innan kerfisins.
2. Insert round insulation material (the type you fit around cold water pipes to stop them freezing during winter) into the bore of the mast.

AÐ SKIPTA UM SNÚNINGSLEGUR
Remove the generator from its mounting, taking off the tailfin and fan assembly. Remove adaptor-locking bolt and brush cover. Remove the bottom cover (2 screws). Clamp the pivot shaft in a vice, using jaw protectors so as not to damage the pivot shaft. Then, using a hammer against a piece of wood to protect the casting paintwork, tap out the pivot shaft assembly by hitting the base of the casting. The bearings can now be removed from the pivot shaft. Use Loctite bearing fit when refitting the new bearings to the pivot sshaft andto the generator housing. Apply silicone sealant to the bottom cover and the output wires within the adaptor when reassembling the pivot shaft assembly. Refit the brush cover using a new brush cover gasket.
