- Page 2 1. ERROR MESSAGES The machine can recognise a certain number of malfunction conditions and signals them by displaying the relevant messages. – A – Notice Messages wheel not suitable for performing sensitivity calibration - use a wheel of average size (typically 5.5”X1440”) or a larger wheel weighing no more than 40 kg.
- Page 3 First calibrate sensitivity and then set the zero position for the assembly. If the message persists, check the following: that the search card reads correctly by performing the encoder test (see paragraph “Service programmes”); PK modules and phases as indicated in the paragraph “Service Programmes”. E 3 I/E 2/3 Error condition at end of sensitivity calibration.
- Page 4 Unbalance values greater than 999 grams. 2. TROUBLESHOOTING The wheel balancer is equipped with self-test and self-diagnosis programmes supplying information about most possible faults and the relative interventions (refer to the list of error messages and the paragraph “Troubleshooting” in the User Manual). There are, however, irregular working conditions that the machine is not able to recognise, and which are listed below.
- Page 5 - place the terminals of a tester (used as an alternating voltmeter) in contact with the terminals of the disconnected cables; • press the START key. If the piloting part upstream of the measuring point is working correctly, you should read a voltage value of around 115/230 Volts (based on the type of power supply used).
- Page 6 If the motor does not start up: - check that the motor power supply cable is connected correctly; - check motor operation. If when commanding the spin (or when lowering the guard or pressing the Start key and the button) the wheel turns in the opposite direction (i.e.
- Page 7 Check that the CF was inserted correctly in the graphic card and replace the CF if necessary; • the machine resets. The fault (usually sporadic) can arise due to the temporary absence of a power supply to the main board, or owing to a disturbance or malfunctioning of the main board.
- Page 8 Check the efficiency of the earthing connection of the socket (essential for the correct operation of the machine as well as for safety purposes). the earth cable is correctly connected inside the electric system and on the internal machine parts. 3.
- Page 9 This function allows you: to check with the maximum precision (a tenth of an inch) the match between the values obtained with the sensor and the nominal values of the wheels. - The current value of the angular position transducer of the wheel (encoder), its variation interval, and two numerical values corresponding to the number of impulses counted by the encoder during a spin and the expected value for this count (XXX).
- Page 10 lightly push the search card A in the direction of the metal disc D, tighten the two fastening screws then remove the calibration template. IMPORTANT: after any adjustment or after replacing the encoder board, perform the relative test cycle by performing a spin with a wheel, and check that the two numerical values shown on the right hand side of the row denominated ENCODER TEST in the service environment match.
