too slowly after a measuring run.
If the main shaft does not reach the required speed,
check whether the wheel shaft lock is actuated or
whether the weight of the wheel is excessive. In this
case:
•
Release main shaft lock.
•
Make sure that the shaft with clamped wheel can
rotate freely.
•
Turn the wheel by hand and then press on START
key.
•
If the error cannot be remedied: call service.

300 800 or C10 800
Line voltage under 170 V. Balancing is feasible if the
motor can drive the main shaft to the measuring speed.
Wheel data may be lost.
•
Bring the line voltage to within a range of 200 - 230
-240 Volts with an input transformer.
300 801 or C10 801
Line voltage over 265 V. Damage to the electronic unit
of the machine is likely!
•
Bring the line voltage to within a range of 200 - 230
-240 Volts with an input transformer.
300 804 or C10 804
Line voltage over 275 V. Damage to the electronic unit
of the machine is likely! Turn off mains switch. Any
damage resulting from repeated occurrence of this error
code is not covered by the guarantee.
_ Bring the line voltage to within a range of 200 - 230 -
240 Volts with an input transforme.
Error messages by means of acoustic signals
Error messages can also be indicated by means of

The service technician can locate and eliminate the
corresponding error by means of the number of tones,
their frequency
and duration (long/short) and the length of the pauses.
•
Switch off the machine.
•
