ENGLISH
Causes
1.
External supply off or phase not working.
2.
Fuse blown in the electrical plant.
3.
Control panel fuse blown.
1.
The card has lost the calibration data and factory configuration setting.
2.
One or more calibration or setting phases have not been carried out.
1.
The guard has been raised before completion of measurements.
1.
On start-up (using START key or lowering guard) the wheel was rotating backwards
2.
Motor winding inverted.
1.
The motor cannot reach the revolutions needed for effective balancing
2.
electronic card malfunctioning
3.
electrical plant malfunctioning
1.
Calibration weight has not been applied on the wheel.
2.
The pick-ups have not been connected
1.
The guard has not been lowered.
2.
Guard microswitch broken
1.
Phase difference between the 2 pick-ups is too large.
1.
The left pick-up has not been correctly connected or is defective or the cable is disconnected.
1.
The right pick-up has not been correctly connected or is defective or the cable is disconnected.
1.
Position sensors in optoelectronics defective.
2.
The motor will not turn
1.
Passage through zero sensor defective in optoelectronics
2.
The motor will not turn
1.
Weight out of regulation field (weight necessary for balancing the wheel is above 500 grams)
1.
Wheel data not set.
1.
The signal reading at the right pick-up is lower than that at the left pick-up.
1.
1 Brake pedal operated during the measurement
2.
Motor rotation speed irregular.
1.
The electronic card has found a condition of danger connected to a too-high wheel speed during an inactive
machine phase (the shaft rotates at high speed without the operator having pressed the START command); the
electric power is deactivated.
1.
Some fault in the optoelectronic signals.
COD. 655632 Rev.0
Trouble-shooting
1.
Check that positive/negative and neutral are connected up to balancer.
2.
Replace fuses in electrical plant (blown fuses indicate fault in electric plant)
3.
Replace fuses on control panel (blown fuses indicate fault in electronic part).
1.
Repeat all calibration and balancer configuration stages
2.
Perform missing programming or setting operations.
1.
Wait for end of measuring launch before raising guard.
1.
Ascertain that the wheel is still before start-up and in any case avoid rotating wheel backwards on
START.
2.
Check for correct motor connection.
1.
Check mains voltage (it is probably low)
2.
Replace electronic card
3.
Replace electrical part
1.
Repeat calibration from beginning and apply the calibration weight when instructed in the calibration
procedure (also see "Basic Machine Calibration")
2.
Check pick-up connections.
1.
Lower guard with wheel mounted.
2.
Replace microswitch.
1.
a) check that the calibration weight has been correctly applied;
b) also check machine location; it is probably not stable and is vibrating excessively;
c) if the problem persists after having stabilised the machine correctly, check the sensor and
electronic card connections (and replace if necessary);
d) replace pick-ups;
e) if after replacing pick-ups the problem is not solved, replace the card.
1.
Check left pick-up connection (and replace if necessary).
1.
Check right pick-up connection (and replace if necessary).
1.
a) check optoelectronic card connection.
b) check the optoelectronic card is protected from daylight and cover if necessary;
c) if the defect persists check and if necessary replace the optoelectronic card.
2.
Check electrical part.
1.
a) check optoelectronic card connection.
b) check the optoelectronic card is protected from daylight and cover if necessary;
c) if the defect persists check and if necessary replace the optoelectronic card.
2.
Check electrical part.
1.
a) Check that the wheel is correctly fixed on the flange;
b) find (in any case) the external position, apply a 100 gram weight and launch a run..
1.
Set the wheel data before starting the measuring cycle.
1.
The connections to the two pick-ups might be inverted. Check (and exchange if necessary).
1.
Avoid pressing the brake pedal when the motor is operating.
2.
beware of knocking the machine during the measuring cycle. check mains voltage (probably low)
1.
Switch off the machine, lower the guard and switch the machine back on without moving the wheel; if
the error persists, check (and replace if necessary) the electric or electronic part (control panel or
encoder card).
1.
a) check the optoelectronic card is protected from daylight and cover if necessary;
b) if the defect persists check and if necessary replace the optoelectronic card.
c) check and if necessary replace the control panel electronic card.
