Where do I park the sweep before I fill the bin with grain?
There is a section in the manual called “ Storage Preparation on Page 62 ”. The section says to “Park
the sweep behind the intermediate sumps, so that the sumps are on the auger side of the sweep”. The
sweep should not completely cover the inside sump hole (the one closest to the center sump). You will
have to clean out around the tractor drive and the jack wheels before operation.
Where do I find the track dimensions?
The wheel path dimensions are listed at the front of the Owner’s manual. Your dealer also has a copy
of the path dimensions in his price book. The head jack wheels are not listed on the chart. These are
always 34" from the center of the bin. The area around the center sump must be kept clear for the
head jack wheels to roll.
What do I need to hook electrical power to the Series II Sweep?
The Series II Sweep is designed to operate using 460 volt 3 phase 60 cycle power. The voltage must
be within plus or minus 4% for proper operation. Voltages outside of this range may cause excessive
power draw or other operating problems. Please contact the factory for applications outside of
these parameters.
The power must be locked out before servicing the equipment, entering the bin or resetting the
motor overloads.
The wiring to the GSI supplied control box is the owner’s responsibility and is not included with
the sweep.
Electrical controls and wiring should be installed by a qualified electrician. The conductor cables
should comply with the National Electrical Code and any state or local codes which may apply.
How does the Series II Sweep operate?
The Series II Sweep is designed with a small controller in the control panel door to monitor the load on
the screw motor. It automatically shuts the tractor drive OFF when the screw motor reaches a
percentage of the motor nameplate full load amperage. As the material clears the screw, the amperage
lowers until it reaches a set value and the tractor drive turns back on and moves the screw into the
material. The customer must program the set points into the controller and this setup is fully explained
in the Owner’s manual. We usually start the high set point at approximately 90% of full load amps
(FLA) listed on the motor nameplate and the low set point at 60% of the FLA.
Can I use the same control panel for different size sweeps?
If the different size sweeps use the same size motors, the same control panel can be used for different
sweeps. The controller must be reprogrammed for each sweep.
Why does the controller need to be located at the bin door?
The control panel MUST be mounted OUTSIDE the bin near the door for safety reasons. It must be
located so the operator has a full view of the equipment. It must NEVER be installed inside the bin.
Why do I need a foot switch?
The foot switch has to be plugged into the control panel and depressed before the sweep is
operational. It has a 10' cord so the sweep can only be monitored from OUTSIDE the bin.
