To select a sequence (see Figures 7 and 8 on the following pages):
1. Turn off and disconnect power to the unit.
2. Remove the controller box cover.
3. Move the DIP switches on the DIP switch array labeled SW1 to
one of the sixteen (16) available configurations as shown in
Figure 8.
4. Replace the controller box cover.
5. Reconnect power to the Series 1 controller and prepare the unit
for operation.
4-5 Selecting the Most Efficient Loading Sequence
By selecting the best sequence, you can reduce vacuum motor wear, save energy, and reduce
your need to maintain filters.
1. Begin with a sequence time longer than what is required for your
process.
2. Start up the hopper loader with the Series One controller.
3. Observe the flex hose and the material in which you buried the
pickup probe. Listen to the vacuum motor and the sound that the
material makes as it enters the hopper loader.
4. When the hopper loader is full, the conveying rate drops off
sharply. You can observe this condition in the clear flex hose and
the material container in which you buried the pickup probe.
When the hopper loader is full, the vacuum motor and material
sounds also change.
5. Make a note of the elapsed time from the start of conveying to the
time the hopper loader is full.
6. See Figures 7 and 8; pick the next-shorter sequence. For example,
if the hopper is full by the 90-second point of the conveying
sequence, select the 80-second conveying sequence.
