Trouble shooting
E9
Optimisation / minimisation was not carried out
correctly.
1. Wheel was not exactly centred on clamping means
for at least one run.
2. Tyre was not centred on rim for at least one run.
3. Valve position was not set and acquired correctly
at least once.
4. Wrong reference mark (single or double) was used
when readjusting the tyre.
5. Wheel moved on clamping means during a
measuring run (sudden start or braking).
6. Wheel dimensions were not set correctly.
Repeat optimisation.
E15
Recalibration correction is out of range.
During recalibration values above or below the
calibration value envisaged were found. This message
is only a warning. Press key C to transfer the correction
values to the permanent memory.
Use the clamping means supplied with the machine or
perform basic calibration (Service).
E16
During the fi rst recalibration run the calibration weight
was attached by mistake.
Unscrew the calibration weight and press START.
E17
Wheel slips on clamping means.
The clamping nut is not tightened properly, the main
shaft accelerates too quickly. The machine will stop.
Firmly tighten the clamping nut and in special cases
press the START key for longer.
E83
During a measuring run the values measured are
rendered useless due to outside interference pulses
(e.g.: strong vibrations). The run is interrupted.
Repeat the measuring run.
E88
The main shaft speed exceeds the safety limit.
