On the other hand, it is advisable for the ultrasound-supported
rinsing performed in the sequences
Rinsex.1
and Rinse.3 to be
followed in the sequences Rinsex.2 and Rinsex.4 in each case
for a short time (< 30 seconds) by flow through the holes and
gaps produced by fast (2-3 Hz) oscillation movement with
sufficient deflection (dependent on the positioning 3-5°).
Cleaning medium is rinsed away from poorly accessible parts
surfaces and also removed from the holes and gaps.
The positioning far enough on the outside in the rotating
cleaning basket of the holes and gaps to be flowed through
must be observed as prerequisite for the effectiveness of the
fast oscillation.
Thereby it is advisable to initially divide the intended overall
ultrasound-supported rinsing duration in the standard cleaning
program between the above 2 ultrasonic rinsing sequences and
only spend additional rinse time for the additional fast oscillation
in between.

Drying parameters recommendations
in Expert Mode
16.3.1
Spinning
If permitted by the parts and the parts carrier used (rotating
basket), the drying can be made much easier by spinning of the
remaining rinsing medium in the last rinse step
Rinsex
(usually
Rinse5).
The then still to be evaporated (using vacuum and cleaning
chamber wall heater) amount of the last rinsing medium on the
parts and rotating basket surfaces is then determined by the
duration and effectiveness of the preceding spinning sequences
in
Rinsex.5 (Fig. 16.4)
and
Dry1 (Fig. 16.5)
.
Thereby, after the draining of the medium, there is another
program-independent pre-spinning of 20 seconds duration at
max. 500 rpm without vacuum before every programmed
spinning sequence with duration > 0 so that a larger part of the
spun-off medium can discharge out of the cleaning chamber
into the medium tank when the drain valve is still open. It is not
until afterwards that the programmed spin sequence with closed
drain valve under vacuum <=120 mbar starts with the
programmed parameters for duration and (for logical reasons
higher than 500 rpm) speed.
