Trouble shooting
H28
The gauge was moved too slowly.
Return the gauge the starting position and repeat
the operation, bringing the gauge towards the weight
application point again.
H33
The SONAR doesn't work.
H80
Recalibration was not set up. As a result, it cannot be
performed by the operator.
Press the STOP key to clear the message.
Call the service team for machine calibration.
H82
The self-test was disturbed (e.g.: by turning the wheel).
The message is displayed for 3 seconds, then the
measurement is repeated (max. 10 times) or aborted
by pressing the STOP key.
H90
Wheel acceleration was too slow, or braking was too
weak after a measuring run.
If the main shaft does not reach the required speed,
check that the brake is not activated or the weight of
the wheel is too great. In this case:
Release the brake.
Make sure that the shaft with the wheel clamped on it
can rotate freely.
Turn the wheel by hand then press the START key.
If the error cannot be eliminated, call the service team.
H91
Speed variations during measuring run. The brake
may be ON.
Release the brake.
Make sure that the shaft with the wheel clamped on it
can rotate freely.
Repeat the run.
H946
Incorrect Lifter version selection.
Call the service department.
