Grain Systems Bucket Elevtors, Conveyors, Series II Sweeps PNEG-720-G2 - Manual (Page 16)

3. Introduction
16 PNEG-720-G2 12" and 16" Series II Sweep
Bin Roundness Tolerance
Diameter tolerances are limited by foundation limits and sweep operation as well as
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.
Bin Opening Size
Required for Installation
The tail section is the largest piece of a standard Series II Sweep. The dimensions
for a 16" tail section are 23-1/2" x 55-1/4". If the bin wall is not too thick, this unit
should fit through a 23-1/2" x 47" opening. The dimensions for a 12" tail section are
21-1/4" x 51-1/2". Again, if the bin wall is not too thick, the section should fit through
an opening 21-1/2 x 45".
GSI offers a special Knock Down Sweep, uniquely designed for storage units with
small doors. This sweep is broken into 10 main pieces that can fit through a door as
small as 30-1/2" in diameter for 16", 27-1/2" in diameter for 12" or a 20" x 24"
rectangular door. The components are then assembled inside the storage unit.
Voltage Specification
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.
Electrical Requirements
Electrical controls and wiring should be installed by a qualified electrician. The motor
disconnect switches and conductor cables should comply with the National Electric
Code and any local codes which may apply.
A main power disconnect switch capable of being locked only in the OFF position
should be used. This has been integrated into the control panel after June of 2010.
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 wired into or plugged into the control panel
before the sweep will operate.
