MOUNTING
This Hi-Vi model should be mounted on a flat, stable
surface in one of the two following ways:
Positioned and Fastened
Fasten the unit to the desired surface with bolts or
screws of proper size through the standard rubber
isolators on the base. Use flat washers under the
bolt heads.
Positioned but Not Fastened
Install headless stud pins of proper size into the
rubber isolators. Set the base (with the standard
rubber isolators) into holes in a base plate. If the
drive unit is equipped with the optional coil spring
isolators, spring seats must be used.
DRIVES WITHOUT TRAYS
Drive units are often supplied without trays for use
with trays, chutes or tracks supplied by others. In
this case the chute, track, tray or other equipment
is bolted to the tray mounting plate supplied with
the drive unit. Maximum tray weight for each drive
is 3.0 pounds (1.36 kg). Make sure the drive unit is
installed so the end containing the leaf springs is
facing the direction of material flow (see Figure 1).
The center of gravity of any components attached
to the drive unit should be as close as possible to
the drive unit’s drive line (see Figure 1).
ELECTRICAL CONNECTIONS
NOTE: The Eriez Vibratory Feeder is designed to
be operated from an AC source. It cannot be oper-
ated from a DC source.
All wiring should conform to all applicable elec-
trical codes.
1.
Check the specifications of the power line to
be certain that they are the same as those
shown on the nameplate.
2.
Connect the black and white wires in the feeder
power cord to the power source or to the
terminals in the control box marked “Output”.
3.
Connect the green wire to the ground or to the
lug provided in the control box.
4.
Connect the power line to the terminals in the
control box marked “Line”.
5.
Connect the ground lug in the control box to a
good earth ground (a cold water line is
excellent).
6.
On multiple drive feeders (two or more drives
on one tray) all drives should be wired
electrically in phase. The black wires from each
power cord should be connected together and
the white wires connected together.
YOU ARE NOW READY TO START YOUR VIBRA-
TORY FEEDER.
FIGURE 1
CAUTION: Operation from portable engine
driven power plants.
Varying and unstable line frequency has an adverse
effect on vibratory feeders because they are tuned
mechanical devices, designed around either 50 or
60 cycle operating frequency. Shifts in the operat-
ing point due to changes in frequency cause higher
than normal spring stress, striking and high line cur-
rents. When operating from portable engine-driven
power plants, be certain that the engine is up to
speed and all other loads are started and at running
speed before starting the electromagnetic feeder.
The feeder should always be stopped first when
the engine-driven power plant is shut down.
