7.1
Setting of ultrasonic cleaning process
The ultrasonic acitivity is switched on by the turning knob
„ultrasonic time“ (
Illustration 4.10.1/2 A
).
For short period operation turn the knob to timer operation (1-15
min). The timer starts the ultrasonic operation and switches it
off after the set period of time has run down. If necessary, this
process can be repeated as often as required or be interrupted
before the set period has run down (turn to “off”).
For longer ultrasonic treatment periods turn the knob to the left
into the permanent operation position (
∞
). In this mode there is
no automatic switch-off. The operator must switch off the
ultrasonic operation by hand (turn to „off“).
Caution!
The ultrasonic activity can heat up the medium during
permanent operation even without heating; in this process
temperatures exceeding the set temperature can be reached.
In order to avoid unnecessary heating of the cleaning medium,
in particular with low set temperatures, switch on the ultrasound
only during the cleaning stage (other than for degassing and for
revolution of the bath during heating up).

Setting of ultrasonic intensity
For the treatment of sensitive surfaces the ultrasonic intensity
can be reduced. If in doubt, we recommend to carry out trial
cleaning processes with reduced ultrasonic activity.
The ultrasonic intensity can be controlled in a range between 10
– 100 % at the turning knob „power“ (
Illustration 4.10.1/2 E
).
The ultrasonic intensity can be changed during ultrasonic
operation.
7.3
Setting of ultrasonic frequency
(only on multi-frequency units)
The present unit can be operated with two different ultrasonic
frequencies.
The ultrasonic frequency can be set at the knob „freqency“
(
Illustration 4.10.1 F
). The following frequencies are available:
for the removal of coarse and tenacious contaminations and for
the precleaning of robust surfaces
for the fine cleaning and removal of contaminations from
sensitive surfaces
The frequency can be changed during ultrasonic operation.
25 kHz
45 kHz
