Check For Correct Functioning Of Balancing Accessories; Troubleshooting - Corghi EM 9580 Manual De Uso

E 30
Spin device failure. Switch off the machine and
call in the technical support centre.
E 32
The wheel balancer was jolted during the reading
phase. Repeat the spin.
E 50
Automatic wheel clamping system fault.
Restart the wheel balancer.
If the error persists, request servicing.
E F0
Error in reading the 0 notch.
CCC CCC
Unbalance values greater than 999 grams.
CHECK FOR CORRECT
FUNCTIONING OF
BALANCING ACCESSORIES
Checking balancing accessories allows the oper-
ator to make sure that wear has not altered the
mechanical specifications of flanges, cones, etc.
beyond the specified limits.
A perfectly balanced wheel, which has been
disassembled and reassembled in a different
position, should not show an unbalance value
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 cen-
tring 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.
84
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 instal-
lation 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 (locat-
ed 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
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.
