Safety & function

1.3 General safety rules

Only properly trained personnel shall be allowed to
operate the geodyna 6800 optima balancer.

The machine must be used exclusively for the scope
of application by following the operating indications
container in the manual.

Unauthorised changes and modifications to the
machine relieve the manufacturer from any liability for
damages and injuries that might result there from.

On no account should safety features be removed or
made inoperative. In general any work on the electrical

1

1.2-1

system, during installation or power supply
modifications, must be carried out by a qualified
electrician in line with relevant national standards and
the regulations of the local power station.

Note: Remove jumper X46 prior to insulation

resistances tests (500 V DC) and high
voltage tests (1000 V AC), in line with EN
60204-1 (see electrical diagram).

It should be noted that working with technical
equipment may always involve an unforeseeable
acceptable risk. Therefore the operator should
eliminate such dangers by operating the machine with
care.
The following points should be observed:
use the machine only as a technical work tool for its
specified scope of application only;
always use original accessories, approved by the
manufacturer, in perfect condition and suitable for the
type of work to be carried out;
follow the instructions, notes and technical data of the
machine manufacturer and the manufacturer of the
wheels to be balanced;
wear suitable protective clothing and accessories (e.g.
goggles, safety shoes, etc.);
avoid eye contact with the laser scanners;
do not knock or camper the laser scanners;
carry out a regular cleaning of the laser scanners
glass;
do not rest on the wheel guard whilst the laser scanner
is in operation.

In case of calibration defects there is an internal
diagnostic that prompts contacting service.

1.4 Description of function

The wheel data detection is carried out automatically
and with no contact by 3 laser scanners, with
integrated CCD. The 6800 optima balancer calculates
the co-ordinates of the optimal positions for the
application of balancing counter-weights.

The geodyna 6800 optima balancer can be used to
determine geometric information relative to rim
deformations (deviations of the axis in respect of its
rotation axis, commonly referred to as RUNOUT); to
determine geometric information relative to tire
deformations (deviations of the axis in respect of its
rotation axis). This information is useful for an accurate
diagnosis of the wheel behaviour as well as providing
the operator with useful indications to minimise the
effects of these deformations.

The geodyna 6800 optima balancer is able to
automatically determine the unbalance of the rim or
of the wheel in respect of its rotation centre. At the
end of the measuring run the control software carries
out a matching, that consists in corresponding the top
part of the tire with the bottom part of the rim. The
balancer analyses the overall state of the wheel and
prompts for any repairs required.

1.4-1

The geodyna 6800 optima balancer carries out two
types of runout:

1) radial (on the radius);

2) lateral (on the lateral shift).

The geodyna optima balancer also has the TDI (Tread
Depth Indication) system, which provides a general

indication of tread wear. This function is only active in
OPTIMA mode.

The geodyna 6800 optima balancer can operate in
three distinct modes:

a) MANUAL
b) PROFILING
c) OPTIMA

MANUAL

The machine guarantees the basic functions,
suggesting the position and value of the weights to
apply to the rim. The use is similar to the standard
models; balancers fitted only with the left detecting
device. The MANUAL mode is activated through the
functions menu.

PROFILING

This mode is identifiable on the monitor with the symbol
displayed in fig. 1.4-1 detail 1. The control software
automatically acquires the wheel dimensions during
the measuring run. During the normal measurement
cycle the laser scanner automatically sample the rim
shape (internal and external). The machine optically

5

Safety & function

suggests the exact application point of the weight on
the rim through the laser beam (laser pointer).

LASER POINTER: even if inactive, the
Laser Pointer function is present on the
optima balancer. The machine is set in
geodata arm mode as default. The Laser
Pointer mode can be activated by
contacting service. For the use of the
geodata arm refer to the instructions
contained in the geodyna 6800 basic
manual.

OPTIMA

Identifiable on the monitor with the symbol displayed
in fig. 1.4-2 detail 1. In this mode the balancer, as well
as the profiling, carries out the automatic diagnosis
of the runout and the reading for the TDI function.

1.4-2

1.4-3

Control of the rim only: in OPTIMA mode, clamping
only the rim on the balancer, the laser scanner detects
the absence of the tire. In this condition, the rear laser
analyses the runout on the bead recess in the internal
part of the rim and will prompt to automatically proceed
with the matching.

1.4.1 Switching operating modes

(fig. 1.4-3)
The balancer can be set so that it presents the desired
mode of operation at power-on.

• Set the desired value in the functions menu:

0 - MANUAL;
1 - PROFILING;
2 - OPTIMA.

Keep the F6 key pressed to switch from Profiling to

Optima and vice versa.

Note: refer to the geodyna 6800 basic manual

for the navigation procedure through the
function menus and personal data entry
modalities.

geodyna optima Operator’s Manual

1.4.2 TDI Tread Depth Indication

When run in OPTIMA mode, the machine always
automatically detects the depth of the tread groove at
the centre of the tire and over its whole circumference.

According to the mean value detected and the limit

a

b c

1.4.2-1

value set, the program displays one of the following
Tread Groove indications on screen (Fig. 1.4.2-1):
a) GREEN icon = higher than limit set.
b) YELLOW icon = close to limit.
c) RED icon = below limit set.

Note: The information provided for the operator is

intended as a guideline only. The TDI
function is designed to alert the operator
to the need for a closer examination of
wear on the tread.

The operator can set the tread depth limit value for which
wear information will appear on screen. To change the
limit value go to the “Optima Operating Parameters”
menu (Section 9.7).

1.4.3 Print functions

The FUNCTION screen page includes three print settings
items:

Printing. Field for switching the printer On/Off. Set to
On to enable printing. Set to Off to disable printing.

Paper size. Field for selecting the print format. Activate
the format which matches the paper size used, A4 or
Letter.

Printer type. Field for selecting the type of connection
to the machine PC.

- 0 activates the connection via parallel port.

- 1 activates the connection via USB port.

Operational Selections

9.0 Optima BALANCING

The geodyna optima balancer is fitted with 3 laser
scanners with integrated CCD that guarantee an
accurate detection of the characteristics of any type of
wheel. The laser scanners carry out a series of
geometric measurements on the rim, the tread, the
flange and the profile of the rim and of the whole wheel
with a single measuring run of a few seconds. The
measurements detected are then interpreted by the
integrated pc that provides detailed comparative
evidence with a geometric comparison aimed at
improving the wheel efficiency and can print an
exhaustive diagnostic report.

Note: the following instructions describe the

specific functions of the geodyna 6800
optima wheel balancer in OPTIMA mode.
For operations different from the ones
described refer to the manual for the
geodyna 6800 basic model.

9.1 Balancing

The balancer displays the start screen at power-on (see
geodyna 6800 basic model generic instructions).
The screen in fig. 9.1-1 appears automatically on the
monitor after clamping the wheel or by pressing F4
from the start screen. Keep the F6 key pressed to
select the Optima or the Profiling mode (fig. 9.1-4).

Note: If the Laser Pointer mode was activated

instead of the geodata system, the
balancing screen page appears as
shown in fig. 9.1-1a.

Note: With the Laser Pointer mode switched on,

the image is a true representation of the
actual location of the adhesive weights.
A larger rim cross-section shows the
weights suggested (yellow) or possible
alternatives (grey) in the 6 o-clock zone,
precisely where the laser beam indicates
they should be applied.

F1: to access the rim nominal dimensions screen.
With ALU mode selected, when the geodata arm is
removed, key F1 changes icon (fig. 9.1-2), allowing
relocation of the weight in a different position to the
one suggested.
In contrast, with Laser Pointer mode active the key
appears split in two (fig. 9.1-3): hold down the lower
part of the key and turn the wheel manually to vary the
position of the weight indicated by the pointer. In both
cases, changing the position varies the value of the
weight. Changing position is possible on both wheel
planes. When you change the position of the weight on
one side of the wheel the value of the weight on the
opposite plane turns red to indicate the change of value
and/or angular position.

configuration detected.

Note: The change in the weight application mode

is then automatically suggested for all
wheels with the same dimensions, until
the machine is switched off.

F3: The upper part of the key is described in the geodyna
6800 basic model manual.
Use the lower part of the key to select the Vehicle Type
to be operated on. There are three vehicle types
selectable (fig. 9.1-5): CAR, SUV, TRUCK, with runout
limits suitable for the class of vehicle set for each. The
limit values assigned separately to each Vehicle Type
are:

- First harmonic Wheel radial Runout,

- Peak to Peak Wheel radial Runout and

- Tread Depth.

The values can be changed individually and saved by
the user in the "OPTIMA PARAMETERS" menu.

F5

9.1-7

F4: prints the diagnostic report (the printer must be
active). Pressed again it interrupts the current print (in
this case the key will be blocked).

F5: activates the mode on the spokes. For a correct
detection the spokes on the rim must be equidistant,
of a regular shape and of a minimum number of 3
and maximum number of 12. If the number of spokes
has been detected correctly, a check mark will appear
on the relative key (fig. 9.1-6). If the spokes cannot be
detected, the pictorial as shown in Fig 9.1-7 is displayed.
Pressing F5 will display the values of the two separate
weights to apply on the wheel. Therefore it will not be
necessary to introduce the reference spoke location
data as it has already been detected by the control
software. Proceed directly with the application of the
wheel weights. To exit the Spoke mode, press F5 once
again or remove the wheel.

Operational Selections

If the laser scanners have not been able to detect the
spokes or estimate their location, even if the type of
wheel has been correctly identified, activate the
Advanced Spoke Detection function (Section 10.1) in
the OPTIMA PARAMETERS screen and repeat the
wheel run. In any event, the data with the number of
spokes and their position can be nevertheless
introduced manually
Proceed as follows:

• Keep F5 pressed and contemporaneously manually

rotate the wheel.

• Release F5 when the correct number of spokes is

displayed on the monitor.

• Manually rotate the wheel in order to align one of the

spokes at 12 o’clock.

• Press F5, the control software carries out the

calculation and displays the two weight values,
appropriately divided.

• Fit the weights to the wheel, behind the spokes, as

shown on the monitor.

F6: keeping it pressed changes the mode from Profiling
to Optima. Pressed briefly it accesses the OPTIMA
ENTRY Screen.

9.1.1 Wheel measuring run in
OPTIMA Mode

• Lower the covering guard. If the automatic measuring

run function has not been activated, press the
START key: the balancer carries out the wheel
measuring run piloted by the laser scanners. They
detect the rim profile; measure the wheel runout;
the internal rim lateral and radial and the external
rim lateral and radial.

At the end of the wheel measuring run the balancer
displays any unbalance on the wheel and signals the
points to fit the weights, unless the RUNOUT limits
have not been exceeded, in this case the balancer
automatically suggests the OPTIMA ENTRY procedure.

Press F1 to display the wheel (rim + tire) size data
detected with the wheel measuring run.

9.5 Rim Only Diagnosis

Optima can be used to perform an analysis of the rim
only and to process its structural parameters,
independently of the tire.
If only the rim is clamped, the machine always
automatically recognises the presence of a rim without
the tire.

To activate the "Rim only diagnosis" function:

• enable "1" in the "Optima Parameters" screen at the

"RIM ONLY" item (m, Section 9.6).

• start the run.

During the run measurements are taken on the lateral
internal profiles and on the bead recesses (fig. 9.5-1).
The laser reading positions on the rim are the same as
the contact points obtained with a circle with 16mm
diameter, as shown in figure 9.5-2.

When the run is complete, the graph showing the curves
for the radial Run-out of the right and left bead recesses
appears (fig. 9.5-3).
Only in the RIM ONLY function, the graph shows three
different coloured markers, indicating the first harmonic
peak position for:
Left bead recess - Yellow triangle
Right bead recess - Red triangle
Mean of the entire rim - Grey triangle
When the rim is turned, it will be stopped by the brake
in each peak position, to facilitate rim marking. The

18

9.5-3

geodyna optima Operator’s Manual

9.5-4

peak markings on the rim can then be suitably combined
with the minimum reference present on the tyre.

• press F2 for further information about the rim Runout
(Fig. 9.5-4).
These graphs also show the first harmonic peak
markers, combined with the Position Brake.

The "RIM ONLY" diagnosis uses specific limit values,
irrespective of those used for the whole wheel. The
factory values set are:
First harmonic Radial/Lateral Runout = 0.5
Peak to Peak Radial/Lateral Runout = 0.7.
The values can be changed by the user in the "OPTIMA
PARAMETERS" menu.

Note: Activating the "RIM ONLY" function also

allows a specific printed report to be
obtained (if optional printer is present) for
the rim only "Rim diagnostic report" (see
Section 9.7).

Note: The function lengthens the measuring

cycle to a total of 55 seconds.

9.7 Advanced Spoke Detection

This mode, which can be activated when required, allows
absolute precision when detecting the position and
dimensions of the rim spokes, to allow more precise
behind the spokes placement. If the laser scanners can't
recognise the spokes or the operator decides he is
dealing with a rim with a particularly complex shape,
enable the Advanced Spoke Detection function which
recognises any type of spokes, even those with unusual

Preset value: 1,7 mm (0,068 ince).

e) The wheel data detection scan occurs always during

the first measuring run. This function allows the
exclusion of the activation of the laser scanner in
the following measuring runs, in order to optimise
the operating times whenever it is necessary to
carry out more than one measuring run for the same
wheel. By assigning value “0” the scan occurs
automatically and only at the first measuring run,
after fixing the wheel. By assigning value “1” the
scan occurs automatically at every wheel
measuring run (Preset value).

f) Sets the rim runout measurement (if the value is 0

the measurement occurs only if the threshold is
exceeded; if the value is 1 the measurement
occurs always). Preset value: 0.

g) Runout measurement unit selection in mm or

inches. Preset value: mm.
h) Reset the preset default values.
i) Saves the values set by the operator.
k) Automatically prints when the wheel is removed

(only if the printer is present and active). If the

value is “0” (preset) it doesn’t print, if the value is

“1” it prints.

11.0 Optional functions

The wheel balancer has additional functions, which can
be enabled individually after purchasing the machine.
They are enabled by plugging a software key (fig. 11.0-

1) into one of the USB ports on the back of the machine
(fig. 11.0-2).

Each USB key acts exclusively as an enabling device
and its presence on the machine is essential in order
to use the Optional Functions. The USB key must
remain plugged in constantly until the cycle of the
Function it enables is complete.

You can plug in the key at any moment. The program
recognises the key immediately and the Optional
Function is instantly made available, without the
operator having to perform any other procedures.

The key can also be removed at any moment, disabling
any Optional Functions.

A

THE OPTIONAL FUNCTIONS ARE ONLY ACTIVE
WHEN THE USB KEY IS PLUGGED INTO THE
MACHINE'S USB PORT.
AS SOON AS THE KEY IS REMOVED FROM THE
USB PORT THE OPTIONAL FUNCTIONS ARE NO
LONGER AVAILABLE ON THE MACHINE.

How to use the key:

• Plug the key into one of the USB ports, shown by the
yellow sticker (A fig. 11.0-2), on the back of the
machine.

11.0-2

Keep the key by leaving it plugged into the machine's
USB port.

Operational Selections

11.1 OPTI LINE mode

The OPTI LINE mode is a computerised function
designed to improve the vehicle "PULL" effect, that is
to say, the lateral pull force caused by excessive tread
conicity, as well as to minimise the vibrations caused
by any residual wheel unbalance.

Note: is an optional function which must

be requested and enabled separately.

With the OPTI LINE mode (function only possible in
OPTIMA mode) the balancer analyses a set of wheels,
saving their tread conicity index. When the procedure
is complete the machine selects the best four wheels,
suggesting the order in which they should be mounted
to minimise the lateral pull force they produce on the
moving vehicle.

The "PULL" effect caused by excessive tread conicity,
which cannot be corrected by means of wheel
positioning, can be eliminated thanks to Optima's OPTI
LINE mode, using the "Set of Wheels" procedure.

11.1-1

Start the "Set of Wheels" procedure and the run, then
complete compensation of the unbalance, remove the
wheel from the balancer and finally assign the wheel to
the Set, saving its data. When the procedure is
complete, repeat these operations for up to five wheels.
When the fourth wheel is assigned to the Set, a
suggestion for mounting on the vehicle is provided,
allowing you to conclude the procedure. After entry of
the fifth wheel, the program selects and proposes the
best four wheels with the relative mounting suggestion.

Procedure:

• Check that the key which enables the Optional
Function is plugged in. See section 11.0.

Note: The OptiLine mode is active on the machine

when the specific USB key is plugged in.
If the key is removed the Function is not
available.

• Check that OPTIMA mode is switched on.

• Press F6 to go to the OPTIMA ENTRY SCREEN.

• Press F6 to switch on the Set of Wheels

procedure.

24

Note: When the "Set of Wheels" procedure is on,

the status bar shows the relative icon (Fig.

11.1-1) and key F6 shows the OPTIMA icon
again for exiting and returning to OPTIMA
mode.

The icon indicating the tread conicity angle appears on
the OPTIMA ENTRY screen page (Fig. 11.1-2).

The meanings of the icons are as follows:

1) Tread conicity reading with pull towards LEFT.

2) Tread conicity reading with NEUTRAL pull.

3) Tread conicity reading with pull towards RIGHT.

11.1.1 PULL calibration

The PULL calibration procedure is available if the OPTI
LINE mode is installed.
This procedure is for checking and correcting any
parallax problems between the rear scanner running
plane and the axis of the machine wheel shaft, to
guarantee precision measurement of the tread conicity
indices.
The procedure uses the special Calibration Tool
supplied, on whose front surface the rear laser's beam
must run (Fig. 11.1.1-1).

CAUTION: HANDLE THE CALIBRATION TOOL
WITH CARE. AVOID BUMPS AND KEEP IN A SAFE
PLACE.

Calibration must be carried out regularly.
When using the Set of Wheels procedure, the last
calibration should have been performed within a month.

Error Codes

E400

Pull index user calibration failure

The pull index user calibration performs a scanning of
the flat surface of the calibration flange and calculates
a pull index.
This is compared with the factory/service calibration
(step 7 of C122):

• if the difference is less then 0.5 degrees, OK
is displayed and the user calibrated pull index
overrides the factory/service value for set of
wheels calculations;

• if the difference is more then 0.5 degrees, the
error code E400 is displayed and a service call
is suggested; the machine still runs using the
most recent factory/service calibrated pull
index. This might result in a slight inaccuracy
of the conicity measurement.

Corrective actions:

• press F6 to repeat the procedure

press ESC or STOP to release the brake and exit

the procedure.

17.0 Accessories

17.1 Printer

The ink jet colour printer produces a professional
report that can be delivered to the client as the
balancing certificate. This certificate can function as
an extended guarantee of performance.

17.2 Wheel elevator

It can operate with a balancer, a tire changer or placed
between a balancer and a tire changer. Lifting capacity
up to 90 kg.

17.3 Trolley for Flanges

Designed for the complete range of universal and
special perforated flanges (17.4). This accessory
guarantees maximum safety in stocking.

17-2

17.4 Perforated flanges for screw
stud

A complete range of 6 universal flanges for all European
vehicles. Four flanges designed for North American
vehicles. Including bolts. Special flanges for BMW and
OPEL available. Special flange for custom-built vehicles.

17-3

17-4

17.5 SCA Flange

Adaptor for wheels with closed center hole also known
as UniLug adaptor.

When the SCA adaptor is attached to the geodyna
optima the power clamp system needs to be
switched off in the FUNCTION screen.

The operation of the geodyna optima depends a lot on
the power clamp in order to have the information
addressed to the software during some procedures. In
order not to loose the capability to know if a wheel has
been clamped or not and to keep the procedures identical
a special procedure has been implemented when the
SCA adaptor is attached to the machine.

The operator tells the machine that he clamps or
unclamp the wheel on SCA adaptor by simply
lifting the pedal in the same way as in the standard
procedure with the mid centering device.
