4.3 Test Phase Indicator Lights
Time A
This phase begins the test sequence and determines the time
in which amplitude is increased from 0 to the programmed
setting. Gradual increase of amplitude allows samples with
large amounts of fines, low density or electrostatic tendencies
to gently separate before more severe action generates static
buildup and causes particles to agglomerate.
Time B
This phase determines the time that the test will be run at the
programmed maximum amplitude setting. Most of the testing
time will be in this phase.
Time C
This is the duration needed for the amplitude to decline from
maximum to zero. Each sieve size has an optimum separation
amplitude that decreases with particle size. The gradual decrease
at the end of the test serves to clean up separation of near-sized
particles on each sieve.
Max. Amplitude
This LED is on at any time the programmed maximum amplitude
setting is active.
4.4 Operating Mode Indicator Lights
Run
This LED is active whenever the AutoSiever is in operation.
Pause
This LED is lit when the “PAUSE/RES” button is pressed. In this
mode, the test in progress is interrupted, but the time and am-
plitude settings are saved. When the button is pressed again,
the test sequence resumes. This LED is also lit when the stack
assembly is removed during a run.
Auto
The Auto LED is lit when programming, saving programs or
testing with a saved program.
Manual
The Manual LED is lit when establishing amplitude levels and
sequencing for materials.
The LED Digital display shows all of the settings and values
needed when programming and using the AutoSiever. When
numerical values are entered, they appear in the space for the
right-hand digit and “push” any digit currently displayed to the
left. It may be necessary to enter a series of zeroes if you want
to start from a “clear” display.
