Caution:In order to avoid damaging thefilm of control panel, pleasedont touch the keys with sharp

material.

Composite keys for function conversion

1. [ STOP ] + [ a ] + [ a ]

Conversion keys for the measurement

unit of gram/ounce.First, please press [STOP] button andhold it, thenpress [ a ] and [ a ] at thesame time, the information displayedon the control panel will put out; after

a while, please release button [ a ], [ a ] and [STOP] in turn, theprevious tested data will be redisplayedat once but with another kind of unitsystem.

Note: The different sequence forreleasing the keys may result inthe different data displayed, butit is not necessary for operator to

perform other operations, directlypressing [Start] button is ok.

2. [ STOP ] + [ C ] The keys formeasurement mode selection afterputting down the wheel protection.Please press [STOP] button and hold

it, then press[C] button and hold it; release [ C ]and [ STOP ] button in turn, themeasurement mode will be alternatedbetween Put down the wheelprotection to start measurement andPut down the wheel protection tostart measurement by pressing [START ] button.

3. [ STOP ] + [ FINE ] The keys

for entering the status of measure scale calibration.The self-calibration for measurescale is required to performwhen starting the balancer each

time, otherwise the correctmeasurement status cannot beentered (the detailed informationabout self-calibration will bedescribed later).


5/17

4. [ D ] + [ C ] The keys foroutside parameter calibration before

measurement.The keys are used to calibrate theCPU memories corresponding to thewheelbase, rim width and rim diameter ofdifferent wheels, so as to ensure themeasurement accuracy (it is necessaryto calibrate inboth Auto mode and Manualmode).

5. [ STOP ] + [ OPT ] Keys fordiameter data adjustment of automeasure scale function.The diameter data of different vehiclewheels can be stored into CPU throughthis operation, and the datacan keep stored even after balancershutdown (the detailed operation will bedesd later).

Installation

Transport

It is advisable to transport themachine with a forklift(Fig. 3)l Pay attention to the barycenter of the

machine. Do not tilt the machine muchduring the moving.

l Do not drive the forklift too fast.l Keep the location of the machine on

the forklift as low as possible.l Do not overturn it during the moving(pay attention to

the position of the barycenter).

Attention:

Fig. 4

Unpacking

Fig.3

Special anti-rust oil applied on the preciseparts may attract dust. Clean it whennecessary.

Positioning

The installation positionmust satisfy the requirementof safe work.l The machine should be installed

close to the main power supply.

l The machine should be installed on theeven concrete floor or other floors withhard surfaces. Adjust the anchor boltstill KWB-4XX is level and stable.(Fig.5). In order to fasten themachine reliably, use oneM1235 fastening bolt to fasten themachine on the floor tightly.Otherwise, it will cause vibrationand noise.

l Enough spaces should be kept foroperation and

maintenance. The space should be notless than 1m at

l Open the packing box according to theInstruction on it.

Remove the packing materials (Fig. 4)and check whether the machine isdamaged during the transportation.Confirm whether the main unit,accessory parts, and relativematerials are all included.

l Keep packing materials away fromchildren. If the packing materials may

cause pollution, please dispose themproperly.

l Remove accessories and spare partssupplied with the machine and place

them on a safe place. Then, removethe cabinet fixed on bottom plate ofpacking box and place them at a safeplace.

Note:

In order to use the machine safely andreasonably, LAUNCH suggests installingthe machine at least 0.6m away fromthe wall.

Installation

Attention:l Please place, move, and store

KWB-4XX in accordance withsafety signs on the package

l Never lift the rotary shaft whenmoving, installing or operating KWB-4XX. Otherwise, the rotary shaft maybe damaged.

Make sure that the machine is stable andin good condition after installation. Theninstall KWB-4XX according to thefollowing Setup Instruction.

Step 4: Switch on the machinel Check whether the power supply is in

accordance with the requirements ofthe data plate on the machine

before connection. All connection ofcircuit must be done by professional.l The socket of the power supply

must be installed within the reach ofthe operator. The height should be setat 0.61.7m.

l If the supplied voltage is not stable,please use a voltage regulator.

l The machine must have a goodcabinet ground connection.

Now you have finished the installationof KWB-4XXsuccessfully.

Calibration andAdjustment

Self-calibration Program of the Balancer

Attention:The self-calibration program should be runafter the equipments first installation or ifthe measurement accuracy of theequipment is suspect, to ensure themeasurementaccuracy of thebalancer.

Turn on the power supply switch of the

balancer, install a wheel with medium size

(13 --15 ), input the data of the

wheel rim and press key atthe same time. The control panel willdisplay the information as shown in Fig 16.

Release key, put

down the wheel protection, and press

key to rotate the main-shaft.The control panel will display theinformation as shown inFig 17 when the main-shaftstops rotating.

Fig17

Put down the wheel protection, and attach100g (3.5oz) counterweight on the outsideof the wheel rim. Put down the wheel

protection again, and press key tore-rotate the main-shaft. The control panelwill display the information as shown in Fig18 when the main-shaft stops rotating.

The position sensor can be tested at that

moment. Rotate the wheel manually andslowly, indicator ALUI starts flashing, and0 will appear on the right screen when0 position on the main-shaft passesacross the photoelectric sensor as shown inFig 28.

Fig28

Once the wheel turns by one circle, the[0] will appear on right screen one time.When the wheel rotates to the reversedirection, the indicator ALUS will start

flashing. Press key, a number will bedisplayed on the right screen, which is thedistance between the inner side wall of thewheel rim and the balancer cabinet. Whenmoving the measure scale, this number ischanged, too.

Press key, a number will be

displayed on the leftscreen, which is the diameter of thewheel rim. When swaying the measurescale, this number is changed, too. Press

key at current status to

return to the procedure of calibrating thediameter measure scale.

Press key to return to theprocedure of calibrating the width measurescale.

operation atany time.

Adjustment for Sensors and InsideParameters

Sensor

AdjustmentLevel sensor adjustment (Calibrate it afteradjustment each time, and then check it).When the data at the inner side is larger,please move the level sensor to the right.Release the nut at the inner side first, andthen screw the nut at the outsideclockwise; whenthe data at the inner side is smaller, pleasemove the level sensor to the left. Releasethe nut at the outside first, and then screwthe nut at the inner side counterclockwise.

Adjustment for Inside Parameters

Press key, the control panelwill display the information as shown in Fig

29.

Fig29

Press key, the screen will be

blackened, and then press key to

enter the adjustment for inside

parameters; press key to switch the insideparameters: AnP, 1.-1, PHA and Pro, etc.1. Adjustment for gram number error

When the displayed data is smallerthan the actual data, please adjustAnP higher (about two times of theerror value); adjust itsmaller contrarily.

2. Keep 1.-1 between 05.3. Phase error adjustment:

Rotate the wheel until all fiveindicators at the inner side of thedisplay panel are lit. Observe whetherthecounterweight is at the bottom of thewheel rim or not.If it is, the phase value of PHA shouldnot be changed; if it isnt, the phase

value of PHA should be increased ordecreased.

4. Pro should be set as OFF.

Press key to adjust the parameters.
