Installing Coil Support Structure & Coils for Dual Coil TMD IV
The coil support structure is shipped from the factory partially assembled. Coils are mounted on the cross
members. Refer to Outline, Mounting and Assembly, Coil Stand (D07328C-A003) for assembly information.
Refer to Installation Placement (D07328C-A002) for detailed information about positioning the system
components.
Note
: The coil support structure must be located so that the conveyor will stop before any tramp is discharged.
Use the following procedure to assemble and install the coil support structure and coils on your conveyor.
1.
Assemble the coil support structure and the coils so that all electrical cables for the transmitter and
receiver coils are on the same side of the conveyor.
2.
Mount the transmitter coil to allow it to swing in the direction of belt travel at a height above the belt
so it will clear normal conveyor loads.
3.
The swing arm feature allows high loads to pass without damage. If the transmitter coil is mounted too
high, the system's sensitivity is reduced.
4.
Set the receiver coil located under the belt 1
–
2 in. (25
–
50 mm) below the belt line. The belt must not
rub on the receiver coil.
5.
Mount the coils across the conveyor on the centerline between the two idlers.
6.
Idler spacing at the coil location must be greater than 4 ft (1.2 m). If for mechanical reasons this
spacing is not possible, the distance may be reduced by using rubber impact-type idlers.
7.
Remove all deck plates, cross bracing, and return idlers located within 4 ft (1.2 m) of the receiver coil.
Installing Coil Support Structure & Coils for Under Belt Single Coil
TMD IV
The coil support structure is shipped from the factory partially assembled. The coil is mounted on the cross
members. Refer to Under Belt Single Coil Outline and Mounting (D07328C-B101), Under Belt Single Coil,
Assembly Stand, (D07328C-A110) for assembly information. Refer to Under Belt Single Coil Installation
Placement (D07328C-A102) for detailed information about positioning system components correctly.
Note
: The coil support structure must be located so that the conveyor will stop before any tramp is discharged.
Use the following procedure to assemble and install the coil support structure and coil on your conveyor:
Assemble the coil support structure.
Set the coil under the belt 1
