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. 
 

WARNING! 

For all electrical irregularities, before replacing a board you are advised to check: 
- the effectiveness of the wiring between those components probably involved in the malfunctioning. In particular, check: 
- that the connectors are correctly inserted; 
- that the contacts are correctly fixed to the ends of the individual wires of the cables; 
- the stability of the mains voltage in the area where the machine is installed and the efficiency of the earthing system of the shop; 
- for damage to the protection fuses installed in the power supply panel. 
The table below summarises the general wiring diagram. 
 

The machine does not switch on. 

Using a voltmeter, check that there is a power supply voltage on the terminal board of the PEAL32F power supply card. 
1)  If there is no voltage on the PEAL32F card, check: 
- that the power socket and the relative protection fuses are in proper working order; 
- the correct connection of the plug to the machine power supply cable; 
- the mains cable is not damaged; 
- the main switch is working correctly. 
2)  If there is voltage on the PEAL32F card, check: 
- the presence of the voltages envisaged on the PEAL32F card, i.e. from 90V to 250V; 
- the efficiency of the power supply card, checking: 

• that the relative signalling LEDs light up; 

- that the power cable of the MBUGRF main board is installed correctly, and that the cable connectors are connected correctly;  
- any  short-circuits  on  the  peripheral  devices.  For  this  purpose,  detach  all  the  cables  of  the  connectors  of  the  Mother  card,  apart  from  the 

power supply one, and try to switch on the machine; 

- the monitor is powered. Check: 

• the power supply cable is correctly inserted in the power supply panel; 
• the green indicator light is switched on; 

- the monitor, if correctly powered, is working properly. Check: 

• that the signal cable connector is fastened correctly to the MBUGRF board. 

- that the cables of the internal and mechanical external sensor (if installed) are installed correctly - specifically, check: connector JSA2 external sensor 

cable, JDSI2 internal distance sensor cable.

 

• Replace the SD board and, if necessary, the MBUGRF board if the checks described above identified no faulty components. 
 

The picture on the monitor is not correctly visualised: it is not centred, not bright enough, there are strange colours, lines etc. 

- adjust the registers in the front part of the LCD monitor, referring to the manual supplied together with the monitor; 
- check that the monitor signal cable connection to the FPGA graphic card is fastened securely; 

- correctly resynchronise the LCD monitor approved by the manufacturer, as indicated in the “Monitor Auto Setting” programme described in the user 

manual.

 

 

The image of the monitor is distorted.

 

- Check that the screen format setting is correct for the monitor installed on the machine (see paragraph “Selecting monitor display format”) 
 

Pressing the START key and/or lowering the guard, the machine does not perform the spin 

In this case, the different causes can be distinguished on the basis of the display indications. 
1)

 If the monitor continues to show the unbalance values previously calculated.

 

The main board is not receiving or perceiving the START signal arriving from the keyboard or the micro-switch. 
Check: 

• the correct operation of the  automatic  start micro-switch associated with the wheel guard  casing (with the guard lowered, the  contact of 

the switch must be closed); 

• that the automatic start micro-switch is wired correctly 

• the correct operation of the Start key. 
  • Replace the MBUGRF main board if the checks described above identified no faulty components. 

2)

 

If the monitor shows the geometric data of the wheel.

 

The main board receives the signal from the START key or the micro-switch, but the subsequent command is not carried out. 
Check: 
- the “command cable” connecting the Mother board to the “PEAL32F power supply card” is correctly inserted and wired; 
- that the “PEAL32 power board” is working correctly, as described in paragraph “2.1 PEAL32F power board”. To do this, proceed as follows: 
• disconnect the power supply cables of the motor;
