Installation
MOUNTING
P150 and P155 ONLY
The Vibrator should be securely fastened to the
mounting surface, using bolts with lockwashers
or locknuts. The base of the vibrator must
have full contact with the mounting surface
without being forced. To insure full contact with
a surface that is not perfectly flat, use metal
shims as needed between the vibrator base and
the mounting surface.
ELECTRICAL CONNECTIONS
REFER TO FIGURES 1 AND 2
Check the specifications of the power line to be
certain that it is the same as that shown on the
name plate of the vibrator (or controller, if used).
Where no controller is used, connections are
as shown in Figure 1. Where an Eriez controller
is used, connections are as shown in Figure
2. Ground connections should always be
used as shown.
Eriez vibrators cannot be operated by Direct Current.
YOU ARE NOW READY TO OPERATE YOUR
PRECIPITATOR VIBRATOR.

Operation and Maintenance
To start in operation after all connections have been
made, simply turn the unit on. A warm-up period
is not needed.
Eriez vibrators are operated by an alternating
current electromagnet energized directly from any
single phase AC source of the correct voltage
and frequency. No intermediate rectification
equipment is required.
ROUTINE MAINTENANCE AND
CHECKING
In normal operation with the unit properly installed
and the cover in place, the unit will operate with a
solid hammering sound. This steady hammering
sound is a necessary by-product of the metal-
to-metal impacting action of this type of vibrator.
Spurious rattling or tinny noise indicate loose or
resonant parts in the system.
For inspection and checking purposes, units may
be operated temporarily with the cover removed.
The mounting bolts, as well as all fasteners in the
vibrator assembly, should be checked periodically
for tightness. Loose fasteners anywhere in the
assembly or mounting may result in a loss of
efficiency.
Foreign material, if allowed to accumulate on the
E-Frame and moving assembly or on the base,
may also result in loss of efficiency. Such foreign
material may be blown out with an air hose.
These vibrators do not require lubrication
of any kind.
For possible troubles and their remedies, refer to
the Troubleshooting section and Table 1. Service
Chart at the back of this instruction material.
E-FRAME AND ANVIL GAP
ADJUSTMENT
Whenever it becomes necessary to adjust the
E-Frame and anvil gaps (as when parts are
replaced – see Repairs section), use the
following procedure:
a. Loosen the bolts fastening the E-Frame, part
4, (see “Parts List”) and those holding the
spring assembly. Add or remove shims, part
13, equally at each side of the spring assembly,
as shown in Figure 3, until impact pad, part 9,
barely touches anvil part 10. Tighten the bolts
holding the spring assembly.
b. Fasten the E-Frame bolts only finger tight so
that the E-Frame can still be moved as shown
in Figure 4. Using a bar or large screwdriver,
shift the E-Frame to obtain a sliding fit of an
.015" (.4 mm) thick non-magnetic spacer
between the lower side of either armature pole
piece and the adjacent E-Frame leg. After
tightening the E-Frame bolts, the .015" (.4 mm)
spacer should slip easily through the gap from
one side to the other.

P150 Vibrator.

Repairs
SPRINGS
Although spring failure will rarely occur if the unit
is operated within its limitations, springs may
eventually fail. Such failure will cause the unit to
gradually become weak or inoperative. Faulty
springs will be indicated by irregular white areas
adjacent to the spring clamps, or as excessively
worn areas under the edges of the clamps. Refer
to the Parts List and order a new set of springs from
the factory. Be sure to include the serial number
of the unit when ordering.
Note: Springs should be replaced in sets to insure
proper overall springing characteristics.
To install a new set of springs, proceed as follows:
a. Remove the armature, part 3, and the E-Frame.
b. Remove the old spring, noting the relative
positions of the hammer, spring clamps,
spacers, and shims in, the assembly.
c. Reassemble the new springs, hammer, spring
clamps, and spacers on the base, referring to
Figure 4 for relative positions of the parts.
d. Align the parts as shown in Figure 4 and tighten
the outside center spring clamp bolt.
e. Reverse the assembly (turn 180° on base) and
tighten the other center spring clamp bolts.
f. Replace the E-Frame and follow the instructions
given for E-Frame and anvil gap adjustment.
COIL AND E-FRAME (E-FRAME
ASSEMBLY)
Since the coils are permanently embedded on the
center legs of the E-Frame, a coil and E-Frame
must be replaced as a unit. In removing an old coil
and E-Frame, disconnect the old coil by cutting
the leads on the coil side of the crimp connectors,
leaving stubs long enough to properly connect
the new coil.
Then remove the four bolts securing the E-Frame
and slide the E-Frame out sideways (see Figure
5). Before fastening the new E-Frame in place,
the gaps should be adjusted in accordance with
instructions previously given.
When ordering a new E-Frame assembly be sure
to include the vibrator nameplate voltage.

ASSEMBLY
FIGURE 5
ARMATURE
Remove the E-Frame and armature, install the new
armature and tighten, install E-Frame, and follow
E-Frame gap adjustment procedure.
IMPACT PAD AND ANVIL
If it becomes necessary to replace the impact pad,
part 9, or the anvil, part 10, due to possible wear
or breakage it is best to replace both parts. In
replacing these parts, the spring change procedure
given above should be followed, except that it
will not be necessary to unfasten the spring and
hammer at the center.

PERFORMANCE TESTS AND
STANDARDS
All vibrators must meet rigid performance standards
before shipment. Testing is done with standard
loading in a standard test fixture designed by Eriez.
To test the performance of the vibrator, use a
manual voltage controller with sine wave output
(such as a variable auto-transformer) and slowly
apply voltage, starting at zero and increasing to
maximum. Impacting should start at from 5% to
25% of full voltage, with maximum vibratory output
obtained at full voltage.
