Alarm Signal

The machine has a self-diagnostics cycle which 

identifies the most frequent malfunctions during the 

normal work cycle. These malfunctions are processed 

by the system and shown on the display.

Note:

 The information in the POSSIBLE REMEDY 

column requires work to be performed by specialist 

technicians or other authorised people who must 

always work using the Personal Protective Equipment 

indicated in the INSTALLATION manual. In some 

cases, this work can be performed by a normal opera-

tor. Installation Instructions

ERROR

PROBLEM

POSSIBLE SOLUTIONS

Black 

 

 

Wheel balancer does not switch on

•  Verify correct connection to the mains

•  Verify and eventually replace the fuses on the power card

•  Verify monitor function

•  Replace the computer board

Err. 1

No rotation signal

•  Check in self-diagnostics that the encoder functions properly

•  Replace the phase pick-up board

•  Replace the computer board

Err. 2

Speed too low during detection

During the unbalance measurement 

revolutions, the wheel speed has 

fallen to below 42 rpm

•  Make sure that a vehicle wheel is mounted on the wheel 

balancer

•  Use the self-diagnostics function to check the encoder

•  Disconnect the piezo connectors from the board and do a 

spin (if no error is detected, replace the piezo sensors)

•  Replace the CPU board

Err. 3

Unbalance too high

•  Verify wheel dimension settings

•  Check detection unit connections

•  Perform machine calibration

•  Mount a wheel with more or less known unbalance

 (less than 100 grams) and verify the response of the machine

•  Replace the computer board

Err. 4

Rotation in opposite direction

After pressing [START], the wheel 

starts turning in the opposite direc-

tion (anticlockwise)

•  Check in self-diagnostics that the encoder functions properly

•  Check the bearing/spring of the phase generator

Err. 5

Guard open

•  Reset the error

•  Close the guard

•  Verify the function of the protection Switch

Err. 7/

Err. 8/

Err. 9

NOVRAM parameter read error
