Dings Magnetic Group Self-Cleaning Permanent Overhead Magnet - Manual (Page 6)

Revised May 19, 2014
INSTALLATION
A Self-Cleaning permanent overhead magnet is built in 2 types: Inline and Crossbelt. An
Inline type is installed over a conveyor head pulley so that the cleaning belt runs parallel to
the travel direction of material falling off the conveyor. The head pulley must be made from
non-magnetic material. A Crossbelt type is installed over a conveyor so that the cleaning
belt runs at a right angle to the travel direction of the material on the conveyor.
Magnetic performance may be affected by magnetic material in the field. This includes such
items as I-beams, metal supports, hoppers, or splitters. These and other ferrous objects
need to be kept out of the magnetic zone.
Crossbelt Inline
Suspension height is critical to the performance of the magnet. This distance is measured
from the bottom of the magnet face to the surface of the material handling belt.
The magnet should be mounted at the recommended suspension height. IF MAGNET IS
TOO HIGH ABOVE BURDEN, SUFFICIENT MAGNETISM MIGHT NOT REACH INTO THE
BURDEN. TOO MUCH HEIGHT WILL CAUSE A LOSS OF SEPARATION EFFICIENCY.
For best results, crossbelt separators should be centered over the belt and parallel to the
slope of the belt conveyor. Refer to page 6 for maximum conveyor incline.
Electrical Connections
Wiring should be in accordance with prevailing local and national electric codes. Wire size
should be based on the nameplate wattage.
Voltage of magnet terminals should be within + 5% of nameplate voltage.
After electrical connections have been completed, connect a-c power to the motor thru a
motor starter. Be sure line voltage and frequency agree with voltage and frequency shown
on motor nameplate. Check the cleaning belt for correct travel direction.
