2.1 Shaft rotation speed test This menu option is used to run the shaft rotation speed test. This test allows you to control the number of shaft RPMs during the

launch. A number indicating the speed of the shaft will be viewed on the right display.

To access the RPM TEST program, proceed as described below:

Ph.

1 Press on icon.

2 Press on icon.


3 Lower the wheel guard: the

machine will run a launch.

4

NOTE: the speed of rotation also depends on the frequency of the main supply. The

nominal speed of rotation stated in table T11.2 refers to a frequency of 50 Hz. If the

frequency, in that country, is 60 Hz, the speed of rotation will be 20% greater (if motor

and pulley are the same).

If the speed of rotation is much lower than stated, ensure that the main supply voltage

does not drop excessively during rotation. If the main supply voltage is correct, check

the belt tension. If the belt tension is correct, check the motor and the PWRB board.

At the end of the launch, the

screen will display the speed of

rotation in RPM (revolutions per

minute). It is possible to repeat

rotation every time it is necessary.

The nominal speed of rotation

must be between 135 ÷ 145 RPM as stated in table T8.2.


5

Press on icon to exit the RPM TEST

program.

2.2 Pick-up signals test This menu option is used to run the pick-up signals test. This program allows you to check the pick-up signal. To run the test, you will need to mount a preferably balanced steel wheel (complete with rim and tyre) measuring approximately 15” in diameter and 6” in width (or as similar as possible), on the machine. A 50-gram weight must be applied on the external side of the wheel. If the wheel size is different from the measurements provided above, the detected pick-up signals will differ from those stated in

table T8.2. The pick-up signals depend heavily on wheel diameter and width (the greater the diameter, the higher the signal, just as

the greater the width the higher the signal).

To access the PICK-UP SIGNAL TEST program, proceed as described below:

Ph.

1 Mount a preferably balanced steel wheel (complete with rim and tyre) measuring approximately 15” in diameter and

6” in width (or as similar as possible), on the machine.

2 A 50-gram weight must be applied on the external side of the wheel.

Example

Example

Lower the wheel guard: the

machine will run a launch and

display shaft RPM. The machine

will spin continuously and the

pick-up signals at the three

attenuation processes

(Attenuation 1, Attenuation 2,

Attenuation 4) will be displayed in

sequence. Each attenuation value

reading must be between 70 ÷ 120 (See table T8.2).

This sequence repeats until the

wheel stops spinning when the

wheel guard is raised.

If the value of both or one of the

two pick-ups is 0, check the

connection and change the pick-

up, or both, if necessary.


6

Example

Press on icon to exit the SIGNAL

TEST program.

The values of the displayed signals are expressed in an internal number format and not in any international unit of measure.

The attenuation circuit controls the pick-up signals to avoid saturating the input stage of the CPU-LCD board which offers poor results.

If both pick-up signals differ significantly from the values provided in table T8.2 but are similar to each other, check whether:

• The adjustment springs are pre-loaded correctly;

• Both pick-ups are the original ones;

• The CPU-LCD is operating correctly (it is possible to run this check through the VFC TEST described below).

If both pick-up signals differ significantly from the values provided in table T8.2 and differ from each other, check whether:

• The pick-up A and pick-up B cables have been connected to the wrong connectors;

• The pick-up adjustment springs are pre-loaded correctly;


If only one pick-up signal differs significantly from the values provided in table T11.2, check whether:

• The pick-up A and pick-up B cables have been connected to the wrong connectors;

• The pick-up adjustment springs are pre-loaded correctly;

• Both pick-ups are the original ones;



2.3 Voltage – frequency converter test This menu option is used to run the voltage - frequency converter test (or VFC) on the CPU-LCD board. The converter voltage –

frequency test shows two numbers on the displays that represent the electronic control board conversion values.

To access the VOLTAGE - FREQUENCY CONVERTER TEST program, proceed as described below:

Ph.

1 Press on icon.

2 Press on icon.


3

Example

The voltage - frequency converter

test program displays two

numbers that represent internal

conversion values used in the

electronic control board, and

must be between 40.0 ÷ 45.0 (See table T8.2).

If the value of both or one of the

two pick-ups is 0, check the

connection and change the pick-

up, or both, if necessary.

4

Example

Press on icon to exit the VOLTAGE

- FREQUENCY CONVERTER TEST

program.

Il Value A refers to pick-up A VFC, while value B refers to pick-up B VFC. The displayed values must be stable (if no one touches or

bumps into the machine) and must be between the tolerance range stated in table T8.2. If the machine is touched or bumped into,

both VFC channels will vary and re-stabilise when the mechanical interference stops.


PICK-UP SPRING PRE-LOAD ADJUSTMENT For correct operation the pick-up must be pre-loaded with a spring. To do so, the spring must be compressed by a screw, according

to the following:

1. ALL PROCEDURES (INCLUDING MINOR) MUST BE CARRIED OUT BY QUALIFIED STAFF;2. BEFORE PERFORMING ANY PROCEDURE, DISCONNECT THE ELECTRICAL POWER SUPPLY;3. Tighten the hex screw, by hand, as far as it will go;

4. Repeat step 1 for the other pick-up;

5. Make sure that the springs and hex keys are perpendicular to the pick-up support unit. If necessary, loosen the screw, turn

the spring (or switch it around the other way) and repeat steps 1 and 2 until the set-up is perpendicular;

6. Tighten the screws on the two pick-ups by turning them three full times. It is good practice to spin the two pick-up springs

by a full turn, alternating one at a time. See picture F2.1;

7. Calibrate the machine.

IMPORTANT: Every time a pick-up tightens or loosens, it is compulsory to calibrate the machine.

Example

Example

Turn the shaft and make sure all of

the values between 0 ÷ 255 are read (from 000 to 255 turning

clockwise, and from 255 to 000

turning anti clockwise). When the

reset "notch" on the encoder disc

is in position H12, the displayed

value must be 000 (or it must be

reset to 000 if the value is

different).

If the count is incorrect, clean the

encoder disc; check and/or adjust

the mechanical DEB board

fastening system. If there are no

mechanical problems, then check

the cable and change the encoder

board if necessary.

4. MACHINE CALIBRATION To operate properly, the machine must be calibrated. Calibration allows storing the mechanical and electrical parameters specific to

each machine so as to provide the best balancing results.

4.1 When to carry out machine calibration Table T4.1 lists the cases in which machine calibration should be carried out.

Table T4.1: Conditions for carrying out machine calibration Condition Status Who must perform it

When the machine is installed at the final user. Mandatory Technical Service When the electronic circuit board is replaced. Mandatory Technical Service When a mechanical part linked to the pick-up signals (pick-up, pick-up compression springs, suspension unit + shaft) is replaced.

Mandatory Technical Service

When the pick-up compression springs adjustment are modified. Mandatory Technical Service When the encoder disc is replaced. Mandatory Technical Service When a different motorbike adaptor is used since the last calibration for MOTO Wheel Type.

Mandatory Final user and/or Technical Service

When the machine doesn’t show accurate results for balancing. Recommended Final user and/or Technical Service When there are wide and constant variations due to environmental humidity and temperature (for example seasonal changes).

Recommended Final user and/or Technical Service

The machine requires two independent calibrations:

• Calibration for the CAR/SUV Wheel Type (calibration is the same for both types of wheel);

• Calibration for the MOTO Wheel Type (wheels for motorbike).

It is not mandatory to perform both calibrations. If the user exclusively uses the machine to balance auto-vehicle/off-road wheels

(CAR/SUV) he must perform only calibration for the CAR/SUV wheel type.

4.2 Machine calibration for the CAR/SUV Wheel Types Calibration for the CAR and SUV Wheel Types is the same. To perform machine calibration, you must first provide for the following material:

• A balanced wheel (complete with rim and tyre) with steel rim and with the following dimensions: 14” ÷ 16” diameter: 5” ÷ 5.5” width. Do not use wheels with aluminum rims.

• A 50-gram weight (preferably made of Iron or Zinc). To calibrate the machine, proceed as described below:

Ph.

until you see 50 g on the right

display.

13 On the outer side of the wheel, at

12 o'clock, apply the 50 g weight.




14 Keep the wheel guard lowered. The machine will perform a set of short spins to calibrate the function of automatic stop on imbalance position (see chapter SWI Stop the wheel on imbalance). Do not lift the wheel guard and do

not press on icon during this procedure.

15 Calibration is finished: the

machine automatically exits the

calibration program and returns

to the NORMAL mode, ready to

perform the balancing.

16 To exit at any time the calibration

procedure during its progress,

press on icon.


4.3 Machine calibration for the MOTO wheel type The calibration for MOTO wheel type (motorcycle wheels) is completely separated from CAR/SUV wheel type because in the

calibration for MOTO a specific adaptor for motorcycle wheels is used and this slightly the shaft balancing.

If the calibration for MOTO wheel type has not been done and the user try to spin the wheel for balancing in the MOTO wheel type

mode, the machine will not run and will display an error code ERR 031.

To perform machine calibration for the motorbike flange, proceed as described below:

machine will display the message

shown here. Apply the calibration

weight to the inner side, as

shown. The calibration weight

must be applied on the hole

marked with the “CAL”

inscription.


7

Move the motorcycle adaptor to a

stable vertical position with the

calibration weight at the top as

shown in the figure.


NB If the weight position is significantly different from the vertical position, the machine will refuse to perform the spin and it

will display an error code ERR 043. If the motorcycle adaptor is near to the vertical position but not in the precise vertical

position, the machine will spin but at the end of the calibration each balancing spin will have an error in the balancing

angular position of the weights.

calibration weight at the top as

shown in the figure. If the weight

position is significantly different

from the vertical position, the

machine will refuse to perform

the spin and it will display an error

code ERR 043.

11




12 At the end of the spin, the MOTO

wheel type calibration is finished

and the machine will switch to

NORMAL mode, ready to run the

balancing.

13 To exit at any time the calibration

procedure during its progress,

press on icon.

The MOTO wheel type and the

ALU1 Program Type will remain

set and the wheel dimensions will

be those which were

automatically set by the machine

for this kind of calibration.

If you have anomalies during the calibration procedure, the machine will display the error message (for example ERR 025). See

chapter “5. Error codes” to solve the problem and continue/repeat/cancel the calibration in progress. Launches that are interrupted

by lifting the wheel guard can be repeated by lowering the wheel guard back down.

Acquisition of external plane in ALS1 or ALS2 Program Types.

Double beep Warning. A particular condition has occurred that requires the operator’s attention.

Triple beep Function not available or Error. The requested function is not available or an error condition has occurred.

Short Beep + Long beep Storing one or more values in the permanent memory (eeprom) of the circuit board.

One or more values have been stored in the permanent memory of the circuit board (for example, at completion of calibration phases).

Intermittent beep Adjustment. Signal used in some service programs to simplify sensor adjustment.

The acoustic signal is also heard for about two seconds at machine start-up allowing the operator to check the operation of the alarm

(buzzer).

7. SPECIAL VISUAL SIGNALSThe machine gives special visual signals in certain cases. The special visual signals are listed in table T7.1.

Table T7.1: Special visual signals

Signalling Meaning Notes Three decimal points on Imbalance exceeds 999 grams. This signal can be triggered due to:

• Lack of machine calibration;• Incorrect measures of the wheel dimensions;• Incorrect setting of the Wheel Type;• Incorrect setting of the Program Type.

8. TROUBLESHOOTINGTable 8.1: Troubleshooting table

Part Problem Cause Solution SENSORS • The sensors do not read wheel

dimensions.• Disabled sensors.• Interrupted sensor cable.• Blown sensor board (when you

enter the sensor calibrationprograms the calibrationvalues are not displayed).

• Re-enable the sensors.• Change the interrupted cable.• Change the sensor board.

MACHINE • The machine does not turn on. • Fuse on socket.• Power supply unit.• Power supply board.

• Check and change the fuse.• Check and change the power
