- 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”.
