7 - ERRORSDuring machine operation, various causes of faulty operation could occur. If detected by themicroprocessor, they appear on the display as follows:ERRORMEANING1 No rotation signal. Could be caused by faulty position transducer, or somethingpreventing the wheel from turning.2 During the measurement spins, wheel speed had dropped below 60 r.p.m. Checkencoder functioning (see SELF-DIAGNOSTICS) and repeat the launch.3 Unbalance too high.4 Rotation in opposite direction.5 Guard open before start of spin.7 Fault in reading the machine calibration parameters. Repeat the self-calibration.8 Fault in reading the machine calibration parameters. Repeat the self-calibration.9 General fault in memory of the machine calibration parameters. ContactTechnical Service Department.10 Measured width too small. Repeat the automatic width measurement making surethat the preset distance value is correct.11 Speed too high during unbalance measurement spins.12/13/14 Diffi culty in reading the analog signal. Check encoder functioning (see SELF-DIAGNOSTICS). Contact Technical Service Department.15/17 Inside/outside analog signal too high. Contact Technical Service.16/18 Inside/outside analog signal too low. Contact Technical Service.7.1 - INCONSISTENT UNBALANCE READINGSSometimes after balancing a wheel and removing it from the balancing machine, it is found that, uponmounting it on the machine again, the wheel is not balanced.This does not depend on incorrect indication of the machine, but only on faulty mounting of the wheelon the adapter; i.e. in the two mountings, the wheel has assumed a different position with respect to thebalancing machine shaft centre line. If the wheel has been mounted on the adapter with screws, it couldbe possible that the screws have not been correctly tightened, i.e. crosswise one by one, or else (as oftenoccurs) holes have been drilled on the wheel with too wide tolerances.Small errors, up to 10 grams (0.4 oz) are to be considered normal in wheels locked by a cone; the error isnormally greater for wheels fastened with screws or studs.If, after balancing, the wheel is found to be still out-of-balance when refi tted on the vehicle, this could bedue to the unbalance of the car brake drum or very often due to the holes for the screws on the rim anddrum sometimes drilled with too wide tolerances. In such case a readjustment could be advisable usingthe balancing machine with the wheel mounted (For example, see our models L36, L38/2).8 - ROUTINE MAINTENANCESwitch off the machine from the mains before carrying out any operation.8.1 - TO REPLACE THE FUSESThe power supply board, accessible from the rear by removing the rear cover, is fi tted with safety fuses(see Exploded Drawings). If fuses require replacement, use ones of the same current rating.If the fault persists, contact the Technical Service Department.NONE OF THE OTHER MACHINE PARTS REQUIRE MAINTENANCE.I 0226 GB - 26
