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.

FIGURE 1

FIGURE 2

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.

NOTE: All units pictured are of the Model

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.
