1. Introduction
Product Introduction
Congratulations. Your selection of the GSI Series II Sweep is a wise investment. It will give you years of
dependable service. The main function of the Series II Sweep is to clean out the remaining grain, from the
bin, after all gravity unloading has finished. The GSI Series II Sweep is a single pass sweep only. The unit
will only operate in a round grain bin equipped with a center sump in the bin floor. NOTE: The bin manufacturer should be contacted for their recommendations on your bin’s structural integrity. The
following are sweep criteria recommendations.
IssuesRecommendations
A track is required under each of the sweep tires and jack wheels where they travel
over the aeration (steel) floor. This is the case for all steel flooring including full floor
and flush floor aeration. The track should be a minimum of 10 gauge thick and made
from steel. The steel can be galvanized for the jack wheel paths but needs to have a
non-slip coating for the drive tire paths. The drive tire track coating must not be course
Flooring.
enough to damage the drive tires. A Chart on Page 17 is included that shows radius
dimensions locating the points of contact between the sweep and the bin floor. The
dimensions may be used to figure the material quantities of track to support the sweep
across the aeration flooring. The track material is not supplied with the sweep and
must be supplied by the installer or purchased from GSI. The dimensions are
approximate and the assembled sweep should be checked for exact points of contact.
Center sump size.
Number of intermediate sumps.
Routing the power supply to
the sweep.
Floor level tolerance.
If installing a sump with collector ring, the opening will be 42" x 42" for 12" sweep size.
The sump hopper supplied by GSI was designed with sufficient clearance around
the collector ring housing to allow grain to gravity flow through the hopper and be
carried away by the material handling equipment below. 42-3/4" is the maximum
opening size to allow rolling clearance for the casters assembled to the head end jack.
If made smaller, grain flow may be decreased to an unacceptable level.
**Flow of grain is limited to 15000 BPH when using this sump and collector ring
housing assembly. The collector ring housing extends 22-1/2" down from the floor
surface and is approximately 14-1/4" x 14-1/4" in size.
Intermediate sump pumps must be installed on a maximum of 10' centers where the
sweep will be parked during storage. The first intermediate sump should be placed at
a maximum of 10' from the center sumps and the end sump should be no more than
4' from the bin wall.
The extra sumps will help clean out the grain in front of the sweep, reducing the
start-up load. Doing this will save labor dollars and hours of work to dig out the sweep
and will help the sweep during start-up. The sweep is not designed to start-up when
submerged in material. The sweep should be parked behind the intermediate sumps
with sumps on the auger side of the sweep.
The only option is to use the hopper sump with collector ring. This allows the power
to be transferred through a mechanical device in the center sump and does not twist
any cords.
The top edge of the sump hopper and the top edge of the “X” brace support must be
level with the floor. The floor must be level within 3/4" plus (or) minus, preferably less.
Any high or low points must be gradually sloped. The change in elevation should be
no more than 3/4" over 60".
Diameter tolerances are limited by foundation limits and sweep operation as well as
Bin roundness tolerance.
structural issues. For 72' diameter and larger, the overall tolerance would be plus or
minus 1-1/4" on the radius, plus or minus 1" on 42'-66' diameter bins and plus or
minus 3/4" on 30'-39' bins.

1. Introduction
IssuesRecommendations
Bin opening size required
for installation.
Vo ltage specification.
Electrical requirements.
The tail section is the largest piece of a standard Series II Sweep. The dimensions for a
12" tail section are 21-1/4" x 51-1/2". If the bin wall is not too thick, this unit should fit
through a 21-1/2" x 45" opening.
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. Volt ages outside
of this range may cause excessive power draw or other operating problems. Please
contact the factory for applications outside of these parameters.
Electrical controls and wiring should be installed by a qualified electrician. The
conductor cables should comply with the National Electric Code and any local codes
which may apply.
Disconnect and lock out the power before servicing the equipment, entering the bin
or resetting the motor overloads.
The control panel MUST be mounted OUTSIDE the bin near the door. It must be
located so the operator has a full view of the equipment and can see that all personnel
are clear. It must NEVER be installed inside the bin. 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. The thermal protection
cord must also be plugged in before the sweep will operate.

Torque Values to be used when Tightening the Bolts on the Series II Sweep
It takes more force to tighten a 3/4"-10 bolt than to tighten a 1/2"-13 bolt because of its larger diameter. It
also takes more force to tighten a grade 8 bolt than it does to tighten a g rade 5 bolt because of the greater
material strength. A bolt that is waxed or otherwise lubricated requires much less force to tighten. If the
same amount of force is used with a lubricated bolt as with a non-lubricated bolt, the lubricated bolt often
will break.
A suggested initial tightening torque is listed in the Chart below.

NOTE: In order to fine tune the control panel, the bin must have grain in it.
The Series II Sweep is supplied with adjustable overloads that are not set at the factory. These should be
set slightly higher than the Full Load Amp (FLA) value listed on the motor nameplates.
A. Find the desired “High” Amp and “Low” Amp set points.
1. High Amp Set Point: The Amp load the auger draws when the auger flighting is 90% loaded.
This will turn OFF the tractor drive motor. Initially, set the value to 90% of the Full Load Amps
(FLA) listed on the motor nameplate.
2. Low Amp Set Point: The Amp load the auger motor draws when the auger flighting is 10%
loaded. This will turn ON the drive motor. Initially, set this value to 10% over the Amp draw of the
sweep running empty.

6. Start-Up
CAUTION
DO NOT start or stop the auger while it is under load.
CAUTION
Failures may occur if the auger is run full before it has been “polished” during
the “break-in” period.
CAUTION
NEVER operate the auger empty. Operating augers empty for any length of
time will cause excessive wear. NEVER operate the auger at speeds higher
than recommended.
CAUTION
Be aware of any unusual vibration or noises during the initial start-up and
“break-in” period. If anything unusual is detected, immediately shut down the
auger and disconnect and lock out the power supply before servicing.

7. Operation
NOTICE
Gear reducer is shipped without oil. Add the proper amount of the recommended
lubricant before operating. Failure to observe these precautions could result in
damage to or destruction of, the equipment.
Keep out of the bin while the bin sweep auger is in operation. The rapidly moving
sweep auger can cause SERIOUS INJURY or DEATH.
CAUTION
Be alert for any unusual vibrations, noises and the loosening of any fasteners.
If anything unusual is detected, immediately shut down the auger, disconnect and
lock out the power source before servicing.
NEVER enter the bin while the bin sweep is in operation.

operating controls with shovels, brooms or any other objects.
DO NOT attempt to restrain movement of the bin sweep with ropes, bars or
other devices.
NEVER allow an operator to attempt to manually restrain the bin sweep.
DANGER
Operating the Sweep Auger
DANGER
NOTE: The auger capacity can fluctuate greatly under varying conditions. Moisture content, different
commodities, amount of foreign matter and speeds all play a part in the performance of the auger.
Twenty five percent (25%) moisture may cut capacity by as much as 40% under some conditions.
A. Make certain there are at least two (2) people in the work area to monitor operations at all times.
B. Start the bin unloading equipment before starting the bin sweep auger.
C. Shut down the auger as soon as the bin is empty.
D. Consideration should be given to the proper size auger for any intermittent type operations. When
augers are stopped and restarted under full load, it may result in damage to the auger. Using a larger
diameter auger and reducing its load level will be far better than subjecting a smaller diameter auger
to big loads. If an auger is kept from absolute filling, it will make start-up easier and will convey
more efficiently.

11. Troubleshooting
Do I want to buy a pivot or a standard sweep? What is the difference?
The following Figure 11A is of a 12" pivot sweep head end weldment and a 12" standard sweep head
end weldment. There are very few differences between the two. The standard head weldment has the
female pivot tube welded to the drive end of the unit. Two (2) plate braces and one pipe brace support
this tube. The pivot head weldment has a lug welded to the underside of the motor mount plate. This
lug is for attachment of the sweep pivot rod assembly. There is a large hole in the rear plate for the
center support tube assembly to pass through. Next to the large hole is a slot that the center support
mounts to.
Figure 11A
How complete is the Series II Sweep?
With the exception of a few electrical connectors, all components required to assemble your sweep
are included.
How level does my floor need to be for the sweep to operate properly?
The top edge of the sump hopper and the top edge of the “X” brace support must be level with the
floor. The floor must be level within 3/4" plus or minus, preferably less. Any high or low points must be
gradually sloped. The change in elevation should be no more than 3/4" over 60".
Where should the center pivot pin be located?
The center pin or pivot pipe must be in the center of the bin. If it is not, the sweep could hit the bin wall.
There should be between 2" and 14" of clearance between the end of the sweep and the closest
obstruction (bin wall, stiffeners, etc.).
How round must my bin be for the sweep to operate properly?
Diameter tolerances are limited by foundation limits and sweep operation as well as structural issues.
For 72' diameter and larger bins, the overall tolerance would be plus or minus 1-1/4" on the radius, plus
or minus 1" on 42'-66' diameter bins and plus or minus 3/4" on 30'-39' bins.
PNEG-751-G2 12" Series II Sweep 131' and 135' Diameter75
11. Tr oubleshooting
How large of an opening do I need for a standard flow (15000 BPH) center sump?
If installing a GSI supplied sump shell with collector ring, the opening must be 42-1/2" x 42-1/2" x 30"
deep for the 12" sweep.
The sump hopper supplied by GSI was designed with sufficient clearance around the collector ring
housing to allow grain to gravity flow through the hopper and be carried away by the material handling
equipment below it. 42-3/4" is the maximum opening size to allow rolling clearance for the casters
assembled to the head end jack. If the sump is made smaller, grain flow may decrease to an
unacceptable level.
Figure 11B
The open area of this sump is misleading. The collector ring housing sticks down into the sump,
blocking off a portion of the flow. Also, the sweep covers about one quarter of the opening at the top.
We use 75% of the theoretical flow around the housing for the actual flow.
What intermediate sump spacing do I need? Why?
It is required to install the intermediate sumps on a maximum of 10' centers where the sweep will be
parked during storage. The first intermediate sump should be placed a maximum of 10' on center from
the center sump and the end sump should be no farther than 4' from the bin wall. The extra sumps will
help clean out the grain in front of the sweep, reducing the start-up load. Doing this will save labor
dollars and hours of work to dig out the sweep and will help the sweep during start-up. The sweep is
not designed to start-up when submerged in material. The sweep should be parked behind the
intermediate sumps with the sumps on the auger side of the sweep.
Do I need to clean out around the end of the sweep prior to starting it up?
Enough material must be removed from around the tractor drive and the screw drive units to allow
access to the motor/drive covers. Both the chain drive and the belt drive must be free of grain before
and during operation.
76PNEG-751-G2 12" Series II Sweep 131' and 135' Diameter
11. Troubleshooting
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 sa me size motors, the same control panel can be used for dif ferent
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.
PNEG-751-G2 12" Series II Sweep 131' and 135' Diameter77
11. Tr oubleshooting
Can I just run my sweep in the manual mode?
The Series II Sweep is designed to run in the automatic mode. If the sweep is run in the manual mode,
either of the motors may overheat and/or become damaged. Also, excessive amounts of material may
spill over the back board of the sweep.
How do I set my overloads?
The overloads for both motors are adjustable and are not set at the factory. The overload inside the
control panel has a small, usually yellow, dial with numbers on it. Record the full load running amp
value listed on the nameplate attached to each motor. Increase the full load amp value by 10% and
set this number on the overload dial. If the adjustable overloads are set too low, the motors will shut
down as soon as a load is put on them. Disconnect and lock out the power before resetting the
motor overloads.
When do I program my controller?
Initially the sweep should be tested in the manual mode. If it operates properly, then move on to try the
automatic mode.
How do I program my controller for automatic mode?
The Owner’s manual has a detailed set of instructions describing the setup of automatic mode. The
final programming must be performed with material in the tank.
Why does not the auger run while tractor drive is in reverse?
This is a safety feature of the Series II Sweep.
Can I get the unit to reverse while in automatic?
No. This is another safety feature of the Series II Sweep.
What do I do if I encounter any operational problems?
Disconnect and lock out the power before servicing the equipment, entering the bin or resetting the
motor overloads. Look through the troubleshooting section to identify any problems.
There does not seem to be any power to my sweep. What do I do?
Check to be sure the foot switch is depressed. The foot switch has a 10' cord so t he sweep can only be
monitored from OUTSIDE the bin.
The thermal protection cord must be connected before the sweep will operate.
Your electrician should check to make sure there are no loose or shorted connections or wires. It is
possible that one of the components failed after it was tested in our plant and needs to be replaced. A
jobsite electrician can isolate any malfunctioning components. Each fuse should also be checked and
replaced if necessary.
The sweep must be wired according to the Owner/Installation manuals.

11. Troubleshooting
The overload for the screw drive keeps tripping. What do I do?
The overloads for both motors are adjustable. These are not set at the factory prior to delivery and
installation. The overload inside the control panel has a small, usually yellow, dial with numbers on it.
Record the full load running amp value listed on the nameplate attached to each motor. Increase the
full load amp value by 10% and set this number on the overload dial. If the adjustable overloads are set
too low , the motors will sh ut down as soon as a load is pu t on them. Disconnect and lock ou t the power
before resetting the motor overloads.
Check the incoming power at the control box. 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.
Check the incoming power at the motor. Check for balanced phases. If the loads are not properly
balanced between leads, disconnect the motor and check the power leads. By using this method, we
can tell if the imbalance is caused by the motor or is from the incoming power.
The sweep must be wired according to the Owner/Installation manuals.
My tractor drive seems to start and stop too often in automatic. What do I do?
The HYS A (High set point minus low set point) may be set with too large a number. To get maximum
capacity from the sweep, this number should be set as small as possible and not have grain spill over
the sweep backboard.
My controller quits operating. What do I do?
Check to make sure the controller has power. Each of the fuses should be checked and replaced
if required.
If the controller is functioning, it may need to be reprogrammed. Programming instructio ns are included
in the manual that shipped with the sweep. The controller can be damaged by large power fluctuations
or lightning strikes.
My sweep is not operating as well as it did the last time I used it. What do I do?
If the type of material or the density (moisture) of the material changes, the controller set points may
need to be adjusted for maximum output.
Is there any maintenance I need to perform on the electrical system?
None of the electrical components require maintenance. Be sure to disconnect and lock out the power
before servicing the equipment, entering the bin or resetting the motor overloads.
Does any part of the Series II Sweep need lubrication?
The fluid level of each of the gear reducers must be checked before operation. These reducers may
have been shipped dry and require oil before operation.
A complete lubrication section is provided in the Owner’s manual, which shows the type and amount of
lubricant to be used and which components need to be lubricated.
What maintenance should I perform and how often?
Follow the lubrication instructions in the Owner’s manual. Also visually inspect the sweep
before operation.

What should I visually inspect?
Starting from the drive end of the sweep:
Inspect the head jack, caster mounting channel and head casters. Look for any bent or
damaged components.
Inspect the motor covers. They should be in good shape and should be used properly. If the covers are
not used, the material will work its way into the motor cooling slots and when the sweep is started, the
motor fan and housing will be destroyed.
Inspect the belt guard for damage. Make sure there is no material inside the belt guard. The drain pan
at the bottom of the guard can be used if required.
Inspect the drive belts, sheaves and bushings. Check the belts for proper tension. Sheaves and
bushings should be tight.
Inspect the intermediate jacks for any broken or damaged components. Check the jack wheels for
damage. The jacks should operate freely.
Inspect each of the screw flight bearings and hangers for damage. Check to see if the bearings need to
be replaced. All hardware should be tight.
Inspect the screw flights for damage or excessive wear. Check to see if the screws are rusted or pitted.
Inspect the end bearing for damage.
Inspect the end caster (if one was originally supplied) to confirm it is working properly or if it needs to
be replaced.
Inspect the tractor drive chain guard for damage. Make sure there is no material (grain) inside the
chain guard. If there is any material (grain), drain pan which is at the bottom of the guard can be used
to empty the guard.
Inspect the drive chain for damage and proper lubrication. Check for proper tension and confirm the
sprockets and bushings are tight.
Inspect the tractor drive tires for damage or tread wear. Be sure the lug nuts are tight and tires are
installed with the tread direction as shown in the manual.
Inspect the bearings for damage or excessive wear. Replace if necessary.
Inspect the tractor drive motor and gear reducer for damage or excessive wear.
Make sure all hardware is tight.
Inspect the sweep structure for damaged or bent components.
