Operation
If indication H0 appears
•
Exit the OP program and return to the balancing
program by pressing the
STOP key ( 5 ).
The unbalance on the wheel will be displayed.
•
Perform compensation according to the indication.
The optimum optimisation condition has been achieved
and cannot be further improved
.
If indication H2 appears
Silent running cannot be further improved. However,
it is possible to achieve a further weight minimisation
(indications with code
Un .).
Option 1: Weight minimisation
•
Go to the program by pressing the FINE ( 3 ) key.
Indication II - Un.7 or Un.7 - II appears.
Option 2 : Abort optimisation
•
Exit the OP program and return to the balancing
program by pressing the
STOP key ( 5 ).
The unbalance on the wheel will be displayed.
•
Perform compensation according to the indication.
Weight minimisation program
If the rim compensation run was omitted, go immediately
to the weight minimisation program by pressing the
FINE ( 3 ) key (indication Un .), proceed as follows:
•
Clamp the wheel.
•
Position the valve exactly perpendicular to and
above the main shaft.
•
Press ENTER ( 1 ) to acquire the valve position.
Indication Un.4 appears ( Fig. 5-34 )
•
Start the run (START).
The measuring run is carried out. After the measuring
run two indications are possible:
Un.5 - H1
Further optimisation is not recommended, but is
possible.
Un.5 – I (1 reference mark Fig. 5-35 )
Proceed with the UN program.
If indication Un.5 - H1 appears
If indication Un.5 - H1 appears, further minimisation
is not recommended, since the measurement values
are below the pre-set limit values. However, it is
possible to continue minimisation so as to achieve an
improvement, if only slight (e.g.: for critical vehicles).
To continue minimisation:
•
Proceed as specifi ed for Un.5 – I indication.
