Dings Magnetic Group 2 PULLEY EDDY CURRENT SEPARATOR - Manual (Page 3)

EDDY CURRENT SEPARATOR
OPERATION
CAUTION: Do not operate the separator with the
access doors open.
The separator has two motor drives (Fig. 3):
(A) fixed high speed drive which rotates the magnetic rotor
assembly;
NOTE: The rotor is a high inertia load on the rotor motor,
so special consideration must be taken during start-up.
The motor can be started no more than once in a 15
minute period. After shut down, allow the motor to rest
for at least 15 minutes before restarting.
(B) fixed speed drive which runs the conveyor belt at about
400 fpm.
Optional motor controls are located in the control panel (C).
Conveyor belt
Nitrile belt with thermowelded PVC “T”
cleats and PVC “C” sidewalls.
Conveyor belt pulley
Pulley is crowned and there is lagging on the
drive pulley.
Gearmotor.
Belt speed adjustment (if equipped)
See “Start-Up” on page 5 for more information
about belt speed.
If equipped with a variable frequency drive:
The conveyor belt speed is preset to 400 fpm.
The speed is adjustable at the drive from 198 to
440 fpm by pushing and holding one of the
arrow keys on the drive until the desired speed
is reached. The unit reads the speed of the belt
directly in fpm. (Eg: 400/MIN = 400 fpm).
For most applications, a belt speed of
approximately 400 fpm will result in the best
separation.
If equipped with a fixed-speed drive:
The belt speed is fixed at approximately
400 fpm.

Figure 5 - Variable Frequency (VF) Drive for
Conveyor Belt (Optional).
No keys other than speed
adjustment need to be
used, as the main control
panel (Fig. 7) controls the
VF drive. If other changes
to the drive’s programming
are needed, please refer to
the VF manual or consult
Dings. See wiring diagram
for factory settings on
the VF drive.
