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.

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.

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.

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

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.

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:

(1) The error code can be exited in the following ways:
OPERATOR
CONFIRMATION
The machine exits the error code display when the operator presses any key.
OPERATOR ACTION The machine exits from the error code display when the operator performs an action linked to said
error code (for example, ERR 064, brings the Distance sensor back to the rest position).
ONCE The machine displays the error code and its brief description just once, then it returns to the
previous status.
PERMANENT The machine permanently displays this error code until being turned off, therefore the error code
cannot be exited.
