6.3. Setting the Conveying Time
F Do not overfill the hopper loader& The conveying time cannot be set while the unit is in the process of conveying
material.
By correctly setting the conveying time, you can reduce vacuum motor wear, save
energy, and reduce your need to maintain filters:
1. Turn on the hopper loader
2. 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.
3. 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.
4. Make a note of the elapsed time from the start of conveying to the time the hopper
loader is full.
5. Turn the hopper loader off
6. Disable the conveying cycle by disconnecting the dump valve sensor from the
controller. With the dump valve sensor disabled, no demand will be indicated, and
the conveying cycle will not start.
7. Turn the hopper loader on.
8. Use the arrow key to adjust the conveying time to slightly shorter
than it takes to fill the hopper loader. For example, if the hopper is
full by the 30-second point of the conveying sequence, set the
conveying time to 28 seconds.
NOTE: To decrease the load time setting it is necessary to cycle the time setting past 99 and
then to the desired setting. There is no “down” button.
9. With the new time setting entered, reconnect the dump valve sensor. Conveying
should start again.
& The conveying time that was last selected appears in the display.
The conveying time can be set at 1 to 99 seconds.
• If the hopper loader is overfilling, reduce the conveying time.
• If the hopper loader is not filling to capacity, increase the conveying time.
10. Check operation to ensure proper settings. If settings are not right, repeat steps 1-9.
