Err.59

Radial and lateral Sonar readout error.

Lateral and radial Sonar values are insuffi-

cient for correct measurement of radial and 

lateral eccentricity.

1.  Check points Err. 55

2.  Check points Err. 57

Err.65

Printer timeout

1.     Check that a printer is present.

2.  Check the code of the processor card.

3.  Check the printer <-> processor card connection.

4.  Run the printer test function.

Err.66

Printer buffer error

1.  Reset the printer.

2.  Repeat the print function.

Err.70

Error regarding ADC 16 bit readings

1.  Check correct connection cable for distance and diameter gauge 

(CN5/CN4).

2.  Switch off the machine, wait about 30 seconds and switch on 

again .

3.  Replace the PC board.

8 - ROUTINE MAINTENANCE

8.1 - SCHEDULED MAINTENANCE

Switch off the machine from the mains before carrying out any operation.

8.2 - REPLACING FUSES

Remove the weight tray to gain access to the power supply board where the 4 fuses are located (see Exploded 
Drawings).  If fuses require replacement, use ones of the same ampage rating. If the fault persists, contact Technical 
Service.

NONE OF THE OTHER MACHINE PARTS REQUIRE MAINTENANCE.
