C. If there is little to no transport of material with a low vacuum, but the conveyor is still cycling properly.
1.The seals in between the modules may be cracked and leaking.
2.There may be a loose connection somewhere with the hose.
3.There may be too much aspiration.
a. If a sensing injection valve is being used, make sure the feed pressure is between 58-87 psi. If the
feed pressure is over 87 psi, the injection valve will remain open all of the time.
4.The seals inside of the pump may be cracked or worn. Refer to page 27.
5.Does the bottom flap close? - If not please turn to the section with the proper controller.
D. If there is little to no transport of material with a high vacuum, but the conveyor is still cycling properly.
1.The filter may be clogged.
2.Aspiration may need to be added.
3.There could be a clog in the pipeline.
4.The pump may be filled with material.
E. If there is material packed into the conveyor, and it is not dumping out properly.
1.The on time may need to be decreased.
2.The off time may need to be increased.
3.The material may be too damp.
a.The product may be sticky.
b.The compressed air may be damp, adding air to the material being conveyed.
4. Fluidization may need to be added to the conveyor. If it is already part of the conveyor, it may not be
functioning properly. The material would be stuck in the cone section located at the bottom of the convey-
or.
5.The filter air shock may not be working properly.
F. If the filter air shock does not function properly, there wouldn't be a 'bump' to shake the excess material off of
the filter. This can be heard when the bottom flap door opens.
1.Check the connections, both compressed air and from the air shock to the pump.
2.Make sure there is not a kink in the tubing to the air shock.
3.If the tubing has material in it, the tubing must be cleaned out or replaced.
4.The valve on the filter shock should push in and out easily. If not, clean it off and add a little lubrication.
5.If the air shock still won't function properly, the air shock valve may be defective.
G. If there is material coming out of the exhaust of the pump, there is a filter problem.
1.The filter may be worn and need to be replaced.
2.The filter may have been put on wrong. Please refer to diagram on page 18, 19.
3. In either case, the side plate should be removed to look inside of the pump. For optimum performance
there should not be any material in the pump, especially the nozzles. Please refer to page 23 for directions
on maintaining and cleaning the pump.
