sieving process can be interrupted manually at any time.
Press the
button (
H1
)
once
to interrupt the sieving process.
The process time is stopped.

7.3 Speed
The speed display (
H6
) shows the set speed value depending on the setting either in mm or g
(acceleration of gravity). The speed is adjustable between 50 rpm (1 g) and 300 rpm (1.51 g).
When the device is switched on, the last used speed is preset.
Press the "+" or "-" button to set the desired speed.
Press and hold the "-" or "+" button to increased or decreased the speed in fast steps,
respectively.
The speed can also be changed during operation by pressing the "+" or "-" button. An
exceeding or falling below of 300 rpm or 50 rpm respectively is not possible.
The speed can either be displayed as frequency in rpm or as a multiple of gravity g (9.81 m/s
2
),
the so called gravitational acceleration.
Simultaneously press the "+" and "-" button to toggle the display between "rpm" and "g".
During the sieving process, the speed is kept constant within a predetermined tolerance of
0.5 %.
7.3.1 Automatic Unbalance Detection
The AS 400 control is equipped with an automatic unbalance detection. During operation, the
movement of the sieve plate is permanently monitored by sensors. If an unbalance is
registered, i.e. if the sieve plate experiences an excessive acceleration, the sensors
automatically switch off the drive of the AS 400 control.
If an unbalance is detected, the device stops immediately and the display "speed" (
H6
) flashes.
The green LED of the
button (
H2
) extinguishes and the red LED of the
button (
H1
)
lights up. A restart of the AS 400 control is only possible again when the speed has been
reduced.
