Retsch AS 200 control - natural frequency - Manual (Page 17)

Amplitude in „mm“
In display 5, labelled with amplitude mm/g, twice the amplitude is
shown as measured value. We refer to this measured value as
amplitude in our further explanations.
On switching on the AS 200 control the last used amplitude is
displayed.
Adjusting the amplitude from 0.20 – 3.00mm :
4 5 6
Reduction:
Button 4 reduces the amplitude down to 0.20 mm
Keep button 4 pressed – after 5 sec fast adjustment is possible. If
the value drops below 0.20 mm, 3.00 mm reappears.
Increasing:
Button 6 increases the amplitude up to 3.00 mm
Keep button 6 pressed – after 5 sec fast adjustment is possible. If
3.00 mm is exceeded the value 0.20 mm reappears.
Sieve botton acceleration in „g“
Keep buttons 4 + 6 pressed simultaneously for 2 sec.
Changeover to the sieve bottom acceleration mode then takes
place.
After changing over display 5 always indicates 01.0 g.
The required sieve bottom acceleration can now be set and the
machine started.
In display 5 , marked with amplitude mm/g, a multiple of the
acceleration due to gravity „g“ is displayed as measured value
( 1g = 9,81m/s
2 )
On changing over, the associated values of amplitude and sieve
bottom acceleration are converted and displayed only when the
machine is running.
Adjusting the sieve bottom acceleration in “g“
from 1 – 20
Your AS 200 control can of course only reach the sieve bottom
acceleration at which an amplitude of 3.00 mm in relation to the
natural frequency is not exceeded. If the maximum amplitude is
exceeded the display amplitude mm/g flashes uniformly.
4 5 6
Reduction:
Button 4 reduces the sieve bottom acceleration down to 1g.
Keep button 4 pressed – after 5 sec fast adjustment is
possible.
Increasing:
Button 6 increases the sieve bottom acceleration up to approx.
18g
Keep button 6 pressed – after 5 sec fast adjustment is
possible.
Acoustic signal for end of sieving
11 15 16
If the sieving process is brought to an end without interruption, the
end is signalled by an acoustic signal, which is given 5 times.
Switching off the acoustic signal:
Press buttons 11 and 16 simultaneously
This is confirmed by a signal.
Switching on the acoustic signal:
Press buttons 11 and 15 simultaneously
This is confirmed by a signal.
