5.3.3 “Intensity” preselection (power stage)
CAUTION!
Danger of overload and fracture of the sonotrode.
Using the sonotrode at a higher power setting than the maximum
permissable power stage can lead to premature material fatigue and
fracture of the sonotrode.
It is not permissable using the sonotrodes at higher powers stages
than the maximum permissable power stage indicated.
.
IMPORTANT!
Depending on the sonotrode diameter the following power stages are
permissable:
Sonotrode ∅ maximum power stage
1.5 -- 2.4 mm II
3.5 -- 4.0 mm III
Z After switching on the device, power stage I is set.
' Use the lowest power stage in which the stone can be effectively dis-
integrated.
Z Preselect the required power stage by actuating the corresponding in-
tensity button (I = low power, III = high power).
' The power stage selected is indicated by the intensity button lighting
up.
5.3.4 Activation of transducer
Z Activate transducer by actuating the footswitch.
' Via the “Suction Pump control output” (10) the suction rate (power) of
the suction pump increases to the preselected value by send in/out a
signal.
' The “Foot switch actuated” indicator lamp (5) lights up.
.
NOTE!
If the transducer is activated for some time and if the temperature of the
grip becomes excessively high we recommend changing the transducer.
5.3.5 ”Transducer malfunction” warning lamp
Z Lights up in case of a transducer malfunction.
5.3.6 ”Generator malfunction” alarm lamp
Z Lights up if the preselected output power/rate is exceeded or if the U l-
trasound Generator is defective.
' The device switches off, accompanied by an accustic alarm.
