Fig. 16: amplitude mm/”g” display

In the display marked amplitude mm/”g” the double amplitude is shown as the

measured value. Hereinafter this measurement will be referred to as amplitude.

When the AS450 is switched on, the amplitude is pre-set to the last amplitude

used.

5.14.1.1 Setting the amplitude

reducing

• Press the - key (B3) to reduce the amplitude down to 0.2 mm.

Keep the keys pressed down for 5 seconds for fast adjustment.

If the level drops below 0.2 mm, 2.2 mm will appear again.

increasing

• Press the +key (B4) to increase the amplitude to 2.2 mm.

Keep the keys pressed for 5 seconds for fast adjustment.

If 2.2 mm is exceeded, 0.2 mm will appear again.

When switching the AS450 on, the amplitude is pre-set to the last amplitude used

and can be switched to the sieve bottom acceleration mode.

• Keep the + and - keys (B3 and B4) pressed simultaneously for 2 seconds.

The display does not show any measurements straightaway after the switch-over;

the START key must be pressed first before the measurements are displayed.

In the display (Aa) marked amplitude mm/”g” a multiple of the “g” gravitational

acceleration is displayed as a measurement.

(1g = 9.81m/s ²)

5.15.1 Setting sieve bottom acceleration in “g”

from 0.7 – approx. 7 g

Your AS450 can of course only reach the sieve bottom acceleration at which an

amplitude of 2.2 mm is not exceeded in relation to the natural frequency.

reduce:

– button (B3) reduces the sieve bottom acceleration down to 0.7g.

– keep button (B3) pressed – after 5 seconds fast adjustment is possible

increase:

– button (B4) increases the sieve bottom acceleration up to approx. 7g.

– keep button (B4) pressed – after 5 seconds fast adjustment is possible
