ERROR MESSAGES 

The machine is able to recognize a certain number of malfunctions and inform the user of 
their occurrence by displaying the respective messages on the screen. 
Err 1 
Sensitivity calibration error 
-

Perform sensitivity calibration. 

-

The MBC161 board has been changed. Perform sensitivity calibration.  

Err 4 
-

Outside sensor calibration error: perform outside sensor calibration. 

-

Outside sensor not present: click on the Sensor Calibration icon (utility menu) to disable 
the sensor check and clear the display of the error. 

Err 5 
-

Dimensions entered for an ALU program are not correct. Enter the dimensions correctly. 

Err 6 
Error detected in execution of the optimization program. Repeat the procedure from the start. 

Err 7 

-

The machine is temporarily unable to select the program requested. 

-

Carry out a spin and repeat the request.  

Err 8 

Printer out of service; no printer; printer fault.  

Err 9 

-

Unbalance value above 999 grams. 

-

Reduce the unbalance and repeat the spin. 

Err 10   
-

When the machine is switched on, the contacts of the reed microswitch, which indicates 
the standby position of the distance and diameter sensors, are open. Check that the sensor 
is in its standby position. 

-

With the sensor at standby, check that the microswitch cable contacts are closed with a 
tester. 

-

If not, check the adjustment of the microswitch (see above, "Replacing and adjusting the 
reed microswitch"). If the problem cannot be resolved, replace the microswitch. 

-

Check the connection of the cable connecting the microswitch to the circuit board. 

Err 11 
-

Diameter sensor not in standby (fully retracted) position when machine switched on. 
Return the sensor to the correct position. 

-

Distance sensor failure. Press the handle to disable the sensors and enter the data using 
the keyboard. Contact after-sales service. 

Err 12 
-

When the machine is switched on, the sensor standby position reference value is not 5 +/-
1 marks (use function 98 to check) or the sensor is not in the standby position; 

-

Check that the outside sensor connector is connected to the balancing machine's 
connector panel; 

-

If the outside sensor is not mounted, simply select the sensor calibration function to 
cancel the error message. 

Err 20 
Outside sensor calibration error 
-

Repeat the calibration procedure correctly;
