1.4 Description of function

Display and key pad

The display and key pad are arranged on the ergonomic front
panel.

Gauge arm for distance and rim diameter

Entry of rim diameter and distance between left correction
plane and machine is by means of an integrated gauge arm
or also via the key pad. In the latter case the relative function
key is held pressed while the wheel is rotated to choose the
desired inputs and enter them by releasing the function key.
When fitting adhesive weights with the weight holder, the
machine will support the operator in relocating the correction
position.
Rim width is entered via the menu keys and rotation of the
wheel.

Balancing mode

Readings in different balancing modes (weight position on
the rim) can be given on the display, depending on the type of
wheel to be balanced (car, light-truck, motorcycle, PAX, steel
or alloy rim).
Measuring run and measured values
All measurements are taken and stored in one run during
the automatic program. On completion of measurement the
machine stops automatically and the wheel is slowed down
to standstill. Amounts and locations of unbalance are read out
separately for each correction plane. Main shaft lock
The machines have a pedal-operated main shaft lock which
is used to retain the wheel in the correction position so that
the balance weights can be fitted. This lock is designed only
to facilitate orientation of the wheel and must not be used for
braking the main shaft. Store wheel profiles
Wheel profiles permit the storage of values for wheels that
are balanced frequently in order to save having to enter the
wheel data etc. each time. It is possible to store up to 4 wheel
profiles.
Error codes
Errors in operation or failures in the electronic or mechanical
system are signalled via respective error codes (see § 11.
Error codes).
User calibration
If several measuring runs are necessary to balance a wheel
because balance weight size and position have to be adjusted
repeatedly, this is often due to insufficient measurement ac-
curacy.
In such case the operator has the possibility of readjusting the
machine (see § 13. User calibration). Wheel guard
A wheel guard with electric interlocking is mandatory for the
European Union and is part of the standard equipment. The
measuring run may only be started with closed guard. The
electronic unit can be programmed via code C13 so that mea-
surement is started by closing of the guard.
