- 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). 

• the spin motor is not damaged. 
  Carry out this check using a multimeter on the PHOENIX connector connected to the PEAL32F power supply card: 
  PIN3 – PIN6   mains voltage (230/115vac) while spinning or braking               
  PIN4 – PIN5   mains voltage (230/115vac) while spinning or braking 
  PIN1 – PIN2   zero voltage, i.e. thermal overload circuit breaker closed, spin correct 
  PIN1 – PIN2   voltage approx. 3VDC, i.e. thermal overload circuit breaker open, spin NOT performed and error message “E 16” 
  PIN1 GND  
  PIN2 THERMAL OVERLOAD CIRCUIT BREAKER 
  If there is NO voltage across Pin3-Pin6 and/or Pin4-Pin5 there is a power supply card fault, whereas if there is voltage but the machine does 

not spin, there is a spin motor fault. 

 
- for damage to the coil of relay “RL2”, which is used to power the spin motor. If the relay operates correctly, after pressing START (or lowering 

the guard) there will be a mechanical tone coming from the Mother board. Otherwise, replace the PEAL32F power supply card. 

 
If the above checks have not pointed out any faulty components, replace the main board. 
 
 
 
For  the  machine  version  without  a  guard,  check  the  proper  operation  of  the  Start  key  on  the  keyboard  and  of  the  button  to  the  side  of  the 
machine. In the rest position, the button contact must be open whereas it must closed when pressed. 
 

3) The monitor displays the message “A Cr”. 

The Start button was pressed on the keyboard. 
Check: 

- that the guard is lowered when a spin is performed (pressing the START button); 
• 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). 

- in machine versions without a wheel guard but with an additional START button.  

Check soundness of the START button and, if necessary, check soundness of the START key on the keyboard. 

- in machine versions without a wheel guard and without an additional START button. Check soundness of the JUMPER plugged into the Mother 

board's JMCR1 connector.   

If the above checks have not pointed out any faulty components, replace the main board. 
 

4) The monitor show the message “ 

E 30”.

 

If you hear a strange noise, check the status of the pinion.  
If the wheel starts to rotate normally, check the operation of the encoder card, see paragraph “Service programmes”. 
If the motor does not start up: 

- check that the motor power supply cable is connected correctly;  
- check motor operation.  

 

Pressing the Start button and key, the machine does not perform the spin (wheel balancer version without the guard).  

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

1) The monitor continue to show previously calculated unbalance values. 

 The Mother board is not receiving or perceiving the Start signal arriving from the Start button and key. 
Check: 

- the correct wiring of the START micro-switch; 
- the correct operation of the micro-switch and the Start key. 

If the above checks have not pointed out any faulty components, replace the main board. 
 

2) If the geometric data of the wheel appear on the monitor. 

The Mother board receives the signal from the Start button or key, but the subsequent command is not carried out. 
Check: 

-  For  damage  to  the  coil  of  relay  “RL2”,  which  is  used  to  power  the  spin  motor.  If  the  relay  operates  correctly,  after  pressing  START  (or 

lowering the guard) there will be a mechanical tone coming from the Mother board. Otherwise, replace the PEAL32F power supply card.  

- for damage to the spin motor, checking that it is powered with the relative mains voltage. In the case of damage, replace the motor. 

If the above checks have not pointed out any faulty components, replace the main board. 
 

3) The message “A StP” appears on the monitor. 

- Either the Start button or key (or both) was released when the machine was in the spin or acquisition phase.  

 

4) The monitor show the message “E 30” 

If you hear a strange noise, check the status of the pinion.  
If the wheel starts to rotate, check the operation of the encoder card, see paragraph “Service programmes”.
