Programming-Saving-Recalling-Running
After you determine the proper amplitude (power level) for sieving a sample, press
the Manual/Auto key and return the unit to automatic operation. The timing is
programmed in 1/10
th
of a minute intervals. The power level (amplitude) is from 0
to 99% of power.
1) Press the Program key (PGM) until the Time A indicator light starts to blink.
Then enter the duration using the numbered keypad for the power level to rise
from 0 to the maximum power for the run. A minimum default value of 0.1
minutes (6 seconds) is pre-established.
The TIME A, or ramp-up time, is critical with samples containing large
amounts of fines and/or samples of low specific gravity or with tendencies to
acquire electrostatic charge. Gradual power build up allows such particles to
gently separate before the more severe action causes electrostatic charges to
agglomerate the particles. Experimentation may be necessary to determine
whether extended ramp-up times should be used with each sample type.
2) Press the program key until the maximum amplitude light starts blinking, then
enter the percentage of power needed to sift the particles as determined in
Manual mode during Setup Adjustment.
3) Press the Program key again and the TIME B indicator light will start blinking.
Enter the time of the main test duration to be run at a constant maximum
amplitude.
