greater than 10 grams.
When a higher unbalance is found, check all the
accessories carefully and replace the components
that are not in perfect condition (e.g. showing
dents, abnormal wear, flange unbalance, etc.).
Anyhow it is necessary to bear in mind that, if
the cone is used to centre the wheel, satisfactory
balancing results cannot be achieved if the central
hole of the wheel is out-of-round or incorrectly
centred; Better results can be achieved by centring
the wheel using the securing holes.
Bear in mind that any re-centring error made
when the wheel is mounted on the car can be
removed only removed with an "on-the-vehicle
balancing" of the wheel, using an on-the-vehicle
wheel balancer to complement the work of the
wheel balancer.
TROUBLESHOOTING
Below is a list of faults that may occur and that
the user can solve if the cause is found among
those indicated.
For any other malfunction or fault call in the
technical support centre.
Machine does not switch on
(monitor remains switched off)
No power at the socket.
- Make sure that the mains power is present.
- Make sure that the workshop electrical install-
ation is working efficiently.
The machine plug is defective.
- Check if the plug is working properly and replace
it if necessary.
One of the FU1-FU2 fuses of the rear electrical
panel has blown.
- Replace the blown fuse.
The monitor has not been switched on (only
after installation).
- Switch on the monitor by pressing the button
located on the front of the monitor.
The monitor's power supply connector (located
on the rear of the monitor) is not correctly
inserted.
- Check for proper insertion of the connector.
The diameters and width values
measured with the automatic
measuring devices do not match
the rated values of the rims
The internal sensor was not positioned correctly
when measuring.
- Bring the internal sensor to the position shown
EM 9580 - Operator's manual
in the manual and follow the instructions in the
WHEEL DATA ENTRY section.
The external sensor has not been calibrated.
- Perform the sensor calibration procedure. See
warning instructions at the end of the
TION OF THE ULTRASONIC WIDTH SENSOR"
section.
The automatic internal sensor does
not work
The internal sensor was not in the rest position
when switched on (Warning window on the video)
and the Kis knob or ENTER button was pressed,
disabling control of the automatic sensors.
- Return the sensors to the correct position.
START has been pressed and the
wheel fails to spin
(the machine does not start)
The wheel guard is raised (the "A Cr" message
is displayed).
- Lower the guard.
The wheel balancer provides
unsteady unbalance values
The machine was jolted during the spin.
- Repeat the wheel spin while making sure that
nothing affects machine operation while acquis-
ition is in progress.
The machine does not firmly rest on the floor.
- Make sure that the floor support is firm.
The wheel is not locked correctly.
- Tighten the locking ring nut firmly.
Several spins are to be performed
to balance the wheel
The machine was jolted during the spin.
- Repeat the wheel spin while making sure that
nothing affects machine operation while acquis-
ition is in progress.
The machine does not firmly rest on the floor.
- Make sure that the floor support is firm.
The wheel is not locked correctly.
- Tighten the locking ring nut firmly.
- Make sure that the accessories used for centring
are suitable and original.
The machine has not been calibrated correctly.
- Perform the sensitivity calibration procedure.
The entered geometric data are not correct.
- Make sure that the entered data correspond
to the wheel dimensions and correct them if
necessary.
- Carry out the external sensor calibration pro-
cedure (width).
