Check For Correct Functioning Of Balancing Accessories - Mondolfo Ferro MT 3800 LASER Manual De Uso

A Stp
Wheel stop during the spin phase.
A Cr
Spin performed with the guard raised.
Lower the guard to perform the wheel spin.
– E – Error Messages
E 1
Sensitivity calibration missing. Perform the
sensitivity calibration procedure.
E 2
Error condition on sensitivity calibration. Repeat
the sensitivity calibration, paying attention to
the first spin, which must be performed with the
wheel like the subsequent spins.
Take particular care NOT to knock the machine
during calibration.
E 3 I/E 2/3
Error condition at the end of sensitivity calibration.
Repeat the calibration, if the message persists
perform the following checks:
• Correct sensitivity calibration procedure;
• Correct fastening and position of the calibration
weight;
• Mechanical and geometric condition of the
calibration weight;
• Geometry of the wheel used.
E 4
a) Error condition on sensor calibration.
Perform the sensor calibration procedure.
b) External sensor missing. Visualisation of
this error can be disabled by performing
the following procedure:
- Select ultrasonic width sensor calibration
and press the Kis knob or the ENTER
button.
E 6
Error condition when executing optimisation
programme.
Repeat the procedure from the beginning.
E 12
External sensor not present or faulty. Visualisa-
tion of this error can be disabled by performing
the following procedure:
- Select ultrasonic width sensor calibration
and press the Kis knob or the ENTER
button.

E 27
Excessive braking time. If the problem persists,
call in the technical support centre.
E 28
Encoder counting error. If the error occurs
frequently, call in the technical support centre.
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 op-
erator 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, satis-
factory 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.
