Power Source
12. POWER SOURCE
A. The horsepower recommendations are for augering reasonably dry grain. High moisture grain (above 15%) will
require greater power if maximum capacity is to be maintained. The maximum possible capacity will be less
with high moisture grain than with dry grain.
A main power disconnect switch capable of being locked only in the off position should be
used. The switch should be locked out whenever sweep is not in operation.
1. Electric motors and controls should be installed by a qualified electrician and must
meet the standards set by the National Electrical Code and all local and state codes.
2. A magnetic starter should be used to protect your motor when starting and stopping. It
should stop the motor in case of power interruption, conductor fault, low voltage,
circuit interruption or motor overload. Then the motor must be restarted manually.
Some motors have built-in thermal overload protection. If this type motor is used, use
only those with a manual reset.
3. The motor starting controls must be located outside the bin. They must never be
installed on the sweep auger inside the bin. Locate the motor starting controls outside
the bin, but near the bin door so the operator has full view of the operation inside
the bin.
4. Disconnect power before resetting motor overloads.
5. Reset and motor starting controls must be located so that the operator has full view of
the entire operation.
6. Make certain all electric motors are grounded.
7. Shut off power to adjust, service or clean.
Use the table below to determine the horsepower and electric motor pulley size your specific
sweep requires. Use an electric motor that operates at 1750 RPM (motor pulley not furnished).
