Intermittent – continuous operation
7 8 9 10 11
When the AS400 control is switched on, intermittent operation is
initially disabled. In intermittent mode, the machine runs until the
final, controlled standstill, followed by a pause of 2 seconds stand-
still, before the drive starts turning in the opposite direction.
Enabling intermittent mode of 1-10 min. :

Press key 10

The LED above key 10 illuminates

Display 8 shows 2 min.

Pressing key 9 raises the interval period by up to 10 min.
If 10 min. is overshot, start again with 1 min.

Key 7 reduces the interval period down to 1 min.
If 1 min. is undershot, start again with 10 min.
Disabling intermittent mode :

Press key 11

The LED above key 11 illuminates
 Display 8 is extinguished
Setting the speed in "r.p.m." from 050-300
Never start at the maximum speed of 300 r.p.m., but rather increase the
speed slowly. When using sieves with diameters from 400mm and the
max. sieve stack, do not set the speed higher than 200 r.p.m.. Otherwise
the masses set in motion too quickly can displace, causing the AS400 to
tip over. Or fasten the AS400 as described in the chapter "Assembly".

The speed of the sieve disk is shown as a measured value in dis-
play 5 marked with speed/“g“.
The speed is preset to 050 r.p.m. when the AS400 control is
turned on.
Increase :

Key 6 increases the speed up to 300 r.p.m. in discrete steps of
1 r.p.m.

Hold down key 6, after 5 sec. rapid adjustment of 10 r.p.m. is
possible
if 300 r.p.m. is exceeded 050 r.p.m. appears again
Reduce :

Key 4 reduces the speed down to 050 r.p.m. in discrete steps
of 1 r.p.m.

Hold down key 4, after 5 sec. rapid adjustment of 10 r.p.m. is
possible
if 050r.p.m. is undershot, 300 r.p.m. appears again
Setting the sieve plate acceleration in “g“
from 0.04 – approx. 1.51g
4 5 6
When the AS400 control is switched on, the speed is preset to
050 r.p.m. and can be switched to sieve plate acceleration mode by
simultaneously pressing and holding down
keys 4+6 for 2s.
The display 5 marked as speed/“g“ will show a multiple of the
Earth's gravity "g" as the measured value. ( 1g = 9.81m/s
2 )
Reduce :

Key 4 reduces the sieve plate acceleration down to 0.04g in dis-
crete steps

Hold down key 4, after 5 sec. the rapid adjustment function will
commence
Increase :

Key 6 increase the sieve plate acceleration up to approx. 1.51g in
discrete steps

Hold down key 6, after 5 sec. the rapid adjustment function will
commence
