58 PNEG-2343 U-Trough Free Flow Unloading System
10. Troubleshooting
Q: My slide gates will not open?
A:
1. Check floor flange gate slide clearance. (See Page 53 for details.)
2. In colder temperatures moisture can collect and freeze slide gate to the lid.
Q: Why is my unload tube filled with product?
A:
1. The center and intermediate gates were not fully closed before filling the bin. Close the center
gate and the intermediate gates. (See Page 46.)
2. The powerhead door is open when aeration fans are running. Make sure to close the powerhead
door to pressurize the U-Trough and prevent product build up when aeration fans are operating.
Q: My sweep will not advance?
A: Check sweep engagement lever adjustment (See Page 26 for details) problem solved? Yes or No
If No,
Is the sweep flight turning? Yes or No
If Yes,
Is the sweep flight turning but not the elevator drive wheel? Yes or No
If Yes,
Is the elevator drive wheel turning but the sweep is not advancing? Yes or No
If Yes,
Adjust sweep backplate and elevator wheel to be more aggressive. This is done by tilting the
backplate towards the pile. (See Page 32.)
Q: My sweep will not disengage?
A:
1. Check sweep engagement lever adjustment. (See Page 26 for details.)
2. Ensure center gearbox assembly shifter arm is in shifter slot. (See Page 22 for details.)
Q: My sweep is piling grain at the center of the bin?
A:
1. Center gate must be completely open. This is done by using the crank handle to rotate the center
gate control. (See Page 46 for details.)
2. Unload is exceeding the capacity of the take away (i.e. transport auger). (See Page 56.)
3. Some piling of grain around the center is normal, especially when the sweep is 180° from its
parked position.
Q: Grain is avalanching over the sweep backplate?
A: Under normal operation there will be some grain spillage over the backplate. It is important not to
enter the bin while the sweep is operating and is recommended that a second pass of the sweep is
performed to collect any grain that spills over.
