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?
The thermal protection lead 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.
The overload for the screw drive keeps tripping. What do I do?
The overload for the auger motor is adjustable. The auger is not set at the factory prior to delivery and
installation. The overload inside the control panel has a small, 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 overload is 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.
Check the incoming power at the control box. The “X” Series Sweep is designed to operate using
460 Volt 3 Phase 60 Hz Cycle Power, 380V 50 Hz or 600V 60 Hz . 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 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 instructions are included
in the manual that shipped with the sweep. The controller can be damaged by large power fluctuations
or lightning strikes.
