6. ACOUSTIC SIGNALS
The machine emits different acoustic signals based on its status. The acoustic signals are listed in table T6.1.
Table T6.1: Acoustic signals
Signalling Meaning Notes
Very brief beep Manual entry of wheel geometric data.
Short beep Selecting a program or a function.
Long beep
Acquisition.
•
Acquisition of a value,
•
Acquisition of the wheel dimensions in the STD
program.
Long beep +
1 Short beep
Acquisition of internal plane in ALS1 or ALS2 Program
Types.
Long beep +
2 Short beep
Acquisition of external plane in ALS1 or ALS2 Program
Types.
Double beep Warning.
A particular condition has occurred that requires the
operator’s attention.
Triple beep Function not available or Error.
The requested function is not available or an error
condition has occurred.
Short Beep + Long beep
Storing one or more values in the permanent
memory (eeprom) of the circuit board.
One or more values have been stored in the permanent
memory of the circuit board (for example, at
completion of calibration phases).
Intermittent beep Adjustment.
Signal used in some service programs to simplify sensor
adjustment.
The acoustic signal is also heard for about two seconds at machine start-up allowing the operator to check the operation of the alarm
(buzzer).
7. SPECIAL VISUAL SIGNALS
The machine gives special visual signals in certain cases. The special visual signals are listed in table T7.1.
Table T7.1: Special visual signals
Signalling Meaning Notes
Three decimal points on Imbalance exceeds 999 grams. This signal can be triggered due to:
• Lack of machine calibration;
• Incorrect measures of the wheel dimensions;
• Incorrect setting of the Wheel Type;
• Incorrect setting of the Program Type.
8. TROUBLESHOOTING
Table 8.1: Troubleshooting table
Part Problem Cause Solution
SENSORS
•
The sensors do not read wheel
dimensions.
•
Disabled sensors.
•
Interrupted sensor cable.
•
Blown sensor board (when you
enter the sensor calibration
programs the calibration
values are not displayed).
•
Re-enable the sensors.
•
Change the interrupted cable.
•
Change the sensor board.
MACHINE
• The machine does not turn on. • Fuse on socket.
• Power supply unit.
• Power supply board.
• Check and change the fuse.
• Check and change the power
supply unit.
• Check and change the power
supply board.
MOTOR
• The motor short circuits at
power on and blows the fuse. • Disconnect the motor from the
power supply board. • Change the motor.
