Installation
Mounting
These Eriez heavy duty Feeders may be mounted in
any of the following ways:
Suspension Mounting
Suspend front and rear of Feeder from cables
attached to the suspension bracket eyebolts. Refer to
Table 1 for suspension cable size. Cables should be
minimum 3/8" (10 mm) dia. standard. Safety cables
are also recommended for suspension mounted
feeders.
Refer to Eriez Vibratory Feeders Hopper Transition
and Installation Guide for additional information.
(VM-3320)
WARNING
Suspension mounting inherently involves
risk of property damage or personal injury to
equipment or personnel located under or near
the machine, should a mounting cable fail.
Suspension component specifications given
in this manual are suggestions only, and final
selection of suspension method is entirely
the responsibility of the user. Select and
use suspension cables with rated capacities
(including reduction factors for clamps, etc.)
that provide adequate safety factors when
the weight of the equipment and all possible
loading conditions and upsets are taken
into account. Consult Eriez at 814-835-6000
if additional Eriez equipment information is
needed to make this selection. As with all
suspended equipment, access to the area
under the machine should be restricted.
Floor Mounting
Mount front and rear of Feeder on the floor
mounting accessories provided as an alternate to
the suspension accessories. The mounting bases
(Part #27 or #28) should be bolted to the floor or other
mounting surface, and the unit, with the floor mounting
springs (Part #24, 25, or 26 on part list), simply placed
on the bases (no fastening necessary). (See Figure 1)
Combined Suspension and Floor Mounting
Any combination of suspension and floor mounting
means may be utilized. The details of any such
combination will, of course, be dictated by the
particular application. The instructions given above
should be followed.
IMPORTANT NOTE:
Special Trays and Attachments
Eriez engineering service should always be consulted
before undertaking the design or construction of
special trays. Neither standard nor special trays as
furnished by Eriez Magnetics should be modified or
attachments made without first consulting us. (See
Eriez Standard Tray Specifications.) Unauthorized
alterations void Eriez’ warranty.
NOTE: Do not suspend from eyebolts threaded
horizontally into the tray or drive housing. Eyebolts
loaded at right angles to their shanks may fail
unexpectedly causing damage to equipment
or personal injury.

Electrical Connections
NOTE: The Eriez Vibratory Feeder is designed to be
operated from an AC source. It cannot be operated
from a DC source.
All wiring should conform to all applicable
electrical codes.
FIGURE 2
Eriez Feeder Control
1. Refer to the schematic and outline drawing
and Instruction Operation Manual for the specific
Eriez control operating your feeder.
2. Check the specifications of the power line to be
certain that they are the same as those shown
on the nameplate of the Feeder and Control.
3. Caution: The cable between the feeder and
control must be of sufficient size for the current and
voltage as indicated on the equipment name tag.
A voltage drop through a cable of insufficient size
for the required distance may result in reduced
feeder displacement while operating.
4. 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. The black wires should
be connected to the positive side of the single-
phase input voltage and the white wires should
be connected to the negative side.
You are now ready to start your vibratory feeder.
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 operating point due to
changes in frequency (+or-1 cycle) cause higher
than normal spring stress, striking and high line
currents which can cause drive and tray failure.
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 feeder.
The feeder should always be stopped first when
the engine-driven power plant is shut down.

6
To start the Vibratory Feeder after all connections
have been made, turn the switch on the control to
the “ON” position and adjust the feed rate by rotating
the control knob. Do not operate the unit with
any associated equipment touching any part
of the unit.
No routine maintenance or lubrication is required,
except that any accumulation of foreign matter should
be periodically removed from between the tray and
the body to prevent restriction of movement of the
vibratory elements.
Adjustment (Tuning)
Eriez feeders, when shipped from the factory with
a tray, are tuned and require no further adjustment.
However, if tray is to be attrached in the field or
replacement liners installed, etc.. final tuning may
be required. In this instance the instructions outlined
below should be followed:
This unit is adjusted by changing the stiffness of the
springing system. Spring stiffness adjustment consists
of varying the number of springs (Part 8, on part list)
at the back of the unit or the thickness of individual
springs. Access to the rear springs is gained by
removing the cover (Part 6, on part list) at the back
of the unit (see Figure 3). In tuning, the front springs
need never be disturbed. In NORMAL OPERATION
at full voltage with the unit fully warmed up, the
displacement of the tray, measured at the back of
the tray or the tray mounting brace is .065" – .070"
(1.65 – 1.78 mm) for 58B, 70B and 75B; .055" –
.060" (1.4 – 1.5mm) for 62B and 65B. Excessive
displacement will result in noisy operation of the unit
and may, if continued, cause damage to components.
Operation
CAUTION
(Please Read Carefully): Only those feeder trays
approved by Eriez are acceptable under the limits
of our warranty. Any modifications, alterations, or
changes of any degree must be approved by the
Eriez Manufacturing Co.This is a tuned device
and the correct tray must be applied to the motor
drive for which it is tuned. NEVER OPERATE THE
UNIT IN A STRIKING CONDITION!
Adjustment (Tuning) Guide
The following general rules should be kept in mind
when making adjustments:
1. To increase the tray displacement, decrease
the stiffness of the spring system.
2. To decrease the tray displacement, increase
the stiffness of the spring system.
The above rules are true where the unit is operating
on the normal side of its tuning curve. If increasing or
decreasing the spring stiffness has an effect opposite
to that noted in (1) or (2) above, it means that the
mass of the tray and/or load has been great enough
to throw the operating point to the reverse side of the
curve, which is undesirable. In this event, the stiffness
should be increased (or the tray-load mass reduced)
until the behavior is in accordance with rules (1) and
(2) above. The unit can then be properly tuned.
Normally spring thicknesses of 5/16", 1/4" 3/16" and
1/8" (7.9, 6.4, 4.8, and 3.2 mm) are used. To serve
as a guide in tuning, the following spring stiffness
figures should be used: 1/4" (6.4 mm) thick spring is
approximately 53% as stiff as a 5/16" (7.9 mm) thick
spring; 3/16" (4.8 mm) thick spring is approximately
44% as stiff as a 1/4" (6.4 mm) thick spring; and a
1/8" (3.2 mm) thick spring is approximately 30% as
stiff as a 3/16" (4.8 mm) thick spring.
Example: to slightly increase the deflection of a unit
a 1/4" (6.4 mm) thick spring could be removed and
replaced with two 3/16" (4.8 mm) thick springs. Or, to
slightly decrease the deflection of a unit, a 5/16" (7.4
mm) thick spring could be removed and replaced with
two 1/4" (6.4 mm) thick springs. These combinations
must be determined by the existing springs on the
rear spring stack.

How To Measure Displacement
With the unit operating, observe where the fine gray
lines on the displacement sticker meet. This point
will be higher or lower as the displacement changes.
Opposite the point where they meet, read amount of
displacement.
FIGURE 4
Tuning with New Tray
In the adjustment of the unit, the following steps
should be followed:
1. Attach the tray (Part 12, on part list) and draw all
bolts tight. Tray mounting studs - the nuts are
torqued per Table 2. Check air gap (See Items 8
and 9 under Coil Replacement.)
2. Energize the unit at the voltage and frequency
shown on nameplate.
3. If a control box is used, turn potentiometer from 0%
to 100% slowly and observe the unit in operation.
a) If a hammering noise is in evidence, the tray
displacement is excessive.
To produce normal quiet operation, increase
the stiffness of the rear spring stack by
substituting a spring of greater thickness for
one or more of the rear springs, or by adding
additional springs until the displacement is
approximately .065" – .070" (1.65 – 1.78 mm)
for 58B, 70B and 75B; .055" – .060" (1.4 –
1.5mm) for 62B and 65B. Additional springs
may be purchased from Eriez (see Parts List
Part 9). Under normal operating conditions,
the unit may be turned “ON” or “OFF” quickly
without any momentary or prolonged
striking noise.
b) If the displacement so measured is
considerably less than .065" – .070" (1.65 –
1.78 mm), decrease the spring stiffness by
substituting springs of lesser thickness. If the
displacement is much more than .065" – .070"
(1.65 – 1.78 mm), increase the spring stiffness
by substituting springs of greater thickness.
In changing tuning springs, put the clamp blocks
(Parts 9 & 10, on part list) back on the same way they
came off (see Figure 3) to ensure smooth clamping
surfaces against the springs. All clamping bolts (Part
19) should have a thread engagement of not less than
one and one-half times the bolt diameter and should
be drawn very tight (see Bolt Torque Information
below on Table 2). If “bottoming” of bolts should
occur, washers of sufficient thickness to prevent such
“bottoming” should be used under the bolt heads.
To insure proper clamping pressure, threads should
be lightly coated with a good molybdenum disulfide
anti-seize compound.
KEEP COMPOUND OFF OF CLAMPING
SURFACES.

Operation (cont.)
Adjusting or Tuning For Various Densities
of Materials
The unit may be adjusted to provide optimum
performance for a specific density of material in the
same manner as described for non-standard trays.
When units are adjusted with the tray empty to a
displacement of .065" – .070" (1.65 – 1.78 mm)
(all standard tray units are so adjusted at factory).
They are set for optimum performance on a material
with a density of 100 lbs/cu ft. (1.6 g/cc) For very
light materials, optimum performance occurs with
displacements above this value (up to .065" (1.7
mm)). For denser materials, optimum performance
occurs with displacements less than .065" – .070"
(1.65 – 1.78 mm).
The basic characteristic of these units is such that
the volume output is virtually constant for materials
from 40 lbs/cu ft to 125 lbs/cu ft (.65 g/cc to 2 g/
cc) when units are equipped with standard trays.
When non-standard trays are used (particularly large
trays), a tuning change is often necessary to provide
optimum performance for a specific material.
Repairs
Coil Replacement
The electrical assembly in a vibratory Feeder may
require replacement due to operation at over-voltage,
or normal aging of the unit. Re-assembly will require
checking and possible re-centering of the air gap
between the E-frame and the permanent magnet
elements. The air gap is directly accessible from the
outside of the unit as described below.
The following procedure should be followed in
removing and replacing the electrical assembly
(see Figures 5 & 6).
1. Remove the bolts securing the electrical assembly
plate to the body casting.
2. Back off the adjusting screws that position the
electrical assembly plate.
3. Pry and lift the electrical assembly from the body
casting, using a sling or some other safe method
of lifting. (See Figure 6).
4. Replace defective electrical assembly (order from
Eriez Parts List).
5. In replacing the electrical assembly, insert it into
its original position in the body casting. DO NOT
FORCE THE ASSEMBLY INTO PLACE. When
properly aligned, the assembly will go in easily,
although there will be a distinct pull exerted by the
permanent magnets in the armature. To overcome
this pull, it may be necessary to guide the plate
with a heavy screwdriver, meanwhile applying
pressure to the top of the plate.

6. Start the electrical assembly plate bolts into the
body casting, tighten bolts and back off 1/4 –
1/2 turn.
7. Tighten the adjusting screws that position the
electrical assembly plate.
8. Remove the nameplate from the side of the body
casting to gain access to air gap. (See Figure 7).
9. Working through the opening in the side of the
body casting (Figure 7) and using a non-magnetic
feeler gauge (furnished with each unit),
approximately .072" (1.8 mm) thick (.090" (2.3 mm)
thick for Model 58B) check the air gaps between
the E-Frame legs and the armature pole pieces.

These gaps should be uniform in width and parallel
and as nearly alike as possible. If they are not, they
should be adjusted by shifting the electrical assembly
plate with the front or rear adjustment screws. In
checking the gaps, the internal parts will be easier
to see if the rear cover (Part 6) is removed.

10. Tighten the electrical assembly plate bolts and
replace the cover nameplate.
Spring Change or Replacement
Although the metallic leaf springs have outstanding
life characteristics, failure may eventually occur,
especially if the displacement is greater than normal.
The symptoms of such failure are:
1. Erratic behavior of the unit,
2. Greatly reduced displacement and
3. Greatly increased and perhaps uncontrollable
displacement.
If spring failure is suspected, the front and rear spring
stacks should be removed, checked and replaced one
stack at a time. Replace broken or cracked springs
with springs of equal thickness.
NOTE: Fractures in springs are not always visible.
Tapping springs to obtain distinctive ring ensures no
fractures present. If sound is dull replace spring as it
has fractures.

Troubleshooting
1. Feeder Not Operating
a. Check fuses.
b. Check input voltage.
c. Check output voltage and current (amps).
d. If voltage is going to feeder coil, check coil for
open or ground.
2. Slow Output Of Feeder
a. Check current on feeder at 100% voltage
with the tray empty. If current is higher than
nameplate reading, check for broken
tuning springs.
b. Check for broken tray mounting studs.
c. Check for cracked welds and cracks in the tray.
d. Check for worn tray or liner.
e. If tray is enclosed, the booting to the inlet and
outlet must be flexible, as not to restrict
tray movement.
f. Check air gap.
3. Feeder Is Noisy
(metal-to-metal striking sound)
a. Check for broken isolation coil springs
(suspended or floor mount).
b. Is the tray rubbing on a hopper, chute work
or anything else in the area.
c. Check air gap per manual.
d. Check current on feeder at 100% voltage
with the tray empty. If the current is higher than
the nameplate reading, then check for broken
tuning springs.
Preventive Maintenance
1. Check suspension, and keep feeder clear
of hopper and all other objects.
2. Check for build-up of product in the tray.
3. Check deflection.
4. Check current on feeder (should be within
nameplate rating).
5. Check liners in tray for wear and loose bolts. If liner
is to be replaced, use same thickness material.
Storage of Equipment
Prior to storage, equipment should be carefully
inspected for shipping damage. Should damage
have occurred, immediately contact freight carrier
and Eriez Manufacturing. Equipment should remain
in its original shipping crate or packaging and be
placed in a clean, dry area.
For electronic controllers, in addition to the above,
a rust inhibitor should be placed inside the control
enclosure. Desiccant must be removed from control
enclosure prior to wiring control. Controls should not
be stored in temperatures above 110°F (43°C).
