  • Page 24: Use Of The Wheel Balancer

    9.0 USE OF THE WHEEL BALANCER 9.1 Presetting of wheeldimensions The balancing data is set by means of an “intelligent” automatic gauge; confirmation of the measurement and the position appear on the display. The round part of the gauge must rest on the rim where the weight will be positioned.

  • Page 25: Et (This Function Is Available Only In The Absence Of The La Sonar)

    9.1.1 ET (This function is available only in the absence of the LA sonar) Enabling the ET function, after the end of the automatic distance and diameter measurement, the wheel balancer suggests the most likely width value for the dimensions just acquired. If necessary, change the width value by pressing the buttons, otherwise proceed with normal balancing.

    c. Following the direction of rotation indicated by the position LED’s, move spoke 2 to12 o’clock and press The value to use for correction in position 2 is displayed. d. Move spoke 1 to the correction position as indicated by the position LED’s INDICATION If the OP function is enabled, see the chapter OPPOSITE POSITION for application of the weights at the bottom.

  • Page 30: Automatic Minimization Of Static Unbalance

    9.7 Automatic minimization of static unbalance Initial unbalance Phase shift 50° Possible approximations static residue static residue static residue static residue With traditional wheel Choice with minimum static balancer unbalance This program is designed to improve the quality of balancing without any mental effort or loss of time by the operator. In fact by using the normal commercially available weights, with pitch of 5 in every 5 g, and by applying the two counterweights which a conventional wheel balancer rounds to the nearest value, there could be a residual static unbalance of up to 4 g.

  • Page 38: Diagnostics

    11.0 DIAGNOSTICS 11.1 Inconsistent unbalance readings In some cases, when a wheel that has just been balanced is repositioned on the balancer, the machine can detect an unbalance. This is not a machine problem but is due to faulty mounting of the wheel on the flange. In other words, when mounting the wheel after initial balancing, it has taken another position with respect to the balancer shaft axis.
