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 the 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.
