Introduction
Italvibras USA stainless steel industrial electric vibrators have been designed and manufactured
in accordance with the most exacting international industrial standards and requirements.
Italvibras USA industrial electric vibrators are constructed of AISI 316 stainless steel. They
are designed for long life at continuous duty and maximum force output. The electric vibrators
are suitable for operation in ambient from -30°C to 40°C (operation outside of this range needs
engineering consideration).
Italvibras USA industrial electric vibrators have been evaluated for installation throughout the
world. Standard ratings include CSA (Canadian Standards Association) Approval, the CE
(European Directive) Mark, EX Approval for Zone 21 (ATEX II2D tD A21 IP66) and Russian
GOST Mark. Check the electric vibrator nameplate for the exact ratings and Approvals for the
specific Model.
The electric vibrator can be referred to by its Model or Type designation or by its Item number.
The vibrator Model or Type designations referred to in this manual are as follows:
MVSS – Continuous duty stainless steel industrial electric vibrator, single or three phase.
General Safety requirements
Read this entire manual before proceeding. Compliance with all company, local and OSHA
regulations is essential. Any electrical work must be done in accordance with all applicable
local and national codes and must be performed only by qualified, licensed and authorized
personnel. Always follow lockout and tag out procedures and requirements and always wear
ear protection when in close proximity to operating vibratory equipment.
Comprehensive adherence to these documents at a minimum is required – The National
Electrical Code NFPA 70, ANSI z244.1 the American National Standard for Personnel Protection
– ockout/Tag out of Energy Sources – Minimum Safety Requirements, CFR 29 Part 1910 –
Control of Hazardous Energy Sources ( ockout/Tag out) Final Rule and CFR 29 Part 1910.15
Occupational Noise Exposure.
Storage
Storage of the electric vibrator should be in an ambient not less than 5°C with a relative
humidity not more than 60%. If the vibrator has been stored for longer than two years, the
vibrator should be evaluated by authorized and trained personnel to ensure that the grease is
intact, that there is no bearing damage such as brinelling and that the ground insulation is
sound and not damaged from condensation.

Installation
Before installing the vibrator, make sure that you have everything that you will need and that
there is no shipping damage. Any product damage should be reported to the delivery service
immediately. Standard metric hand tools will be needed. Carefully handle the electric vibrator.
Dropping or impacting the electric vibrator may damage the bearings.
Welding – Never weld on a bin, hopper or machine with the electric vibrator mounted to it
since the welding may damage the vibrator bearings or electrical circuits. When you do weld,
especially in an enclosed area, make sure that the area is known to be nonhazardous and that
there are no flammable or explosive levels of gases, vapors or dusts.
Mounting Surface – The object of vibration on bins and hoppers is to transmit vibration energy
through the structure to the material within. The mounting surface must be rigid and strong for
this transfer of energy to take place. The mounting surface must also be clean, flat (0.010 in.
across mounting feet maximum), free of paint and have a minimum thickness equal to the
major diameter of the mounting bolt. Also make sure that the electric vibrator feet are clean
and free of debris.
Mounting Plate
The mounting plate should be at least the overall size of the electric vibrator feet. It should be
located on the bin and hopper wall at a height of ¼ to 1/3 of the sloped wall height. The
mounting plate or bracket should extend at least ¾ the length of the sloped wall. Reference
Figure 1. If a second electric vibrator is to be installed to the bin or hopper, install it at a height
of ½ of the sloped wall height and 180° from the first vibrator. Weld the mounting plate or
bracket to the structure wall with skip welds that are 3 in. long then skip 2 in. then 3 in. long
weld, etc. Do not weld at corners of mounting plate within 1 in. of the corner.
Figure 1. Mounting Examples

Safety Cable
Always install a safety cable metal rope from the electric vibrator to a reliable support should
the vibrator become free from its mount and fall more than 6 in. The metal rope should be taut
and positioned above the electric vibrator. Reference Figure 2.
Figure 2. Safety Cable Installation

Mounting Kits
Mounting kits are available from Italvibras USA for frame sizes 00, 01, 10, 20, 30, 40 and 50.
The mounting kits include a channel mount with integral mounting plate, mounting screws
and washers and safety cable kit. Contact Italvibras USA by phone at 815-872-1350.

Mounting Hardware & Torque
Always use new bolts, nuts and compression washers. The bolts should be Grade 5 or 8
(equivalent international designation is 8.8 and 12.9, respectively). Grade 5 bolts are suitable
for a majority of applications. Do not use split lock washers. Use only compression washers.
Table I offers suggested mounting bolt torque values. Always check with the bolt manufacturer
for recommended torque values. Torque the mounting bolts in the proper sequence as shown
in figure 3 so as not to damage casting. After operating vibrator for 15 minutes, disconnect,
lockout/tag out, and torque the mounting bolts a second time. Periodically check the mounting
bolt torque thereafter.

Wiring Electric Vibrator Cont.
Trim the conductors within the wiring box leaving plenty of slack. Next, strip the conductor
insulation for 1/4 in. to 3/8 in. Crimp on closed loop wire connectors. Use only the intended
crimping tool as designated by the wire connector manufacturer. The conductors should be
neatly arranged on the floor of the wiring box. The wires should not cross over each other. See
figure 6.
When wiring the electric vibrator, leave enough slack in the cord so that the cord does not become
taut during operation causing stress on the connections. It is always best to position the cord down
so that should there be any moisture present the moisture would tend to run down instead of into
the vibrator wiring box.
Trim the cord by removing the jacket exposing the conductors and ground wire for approx. 6 in.
Be careful not to cut the conductor or ground wire insulation. oosen the compression nut from
the cord fitting assembled to the side wall of the wiring box on the electric vibrator. Position the
compression nut on the cord and insert the cord through the opening in the side wall of the wiring
compartment. Position the jacket of the cord approx. ½ in beyond the inside wall of the wiring box
wall and secure the compression nut by threading it to a position equal to the “Distance Between
Flats” noted in Table III. Reference figure 5. which pictorially defines “Distance Between Flats”

For wiring diagrams 1A, 1E, 2Aand 2C (Fig.4), reinstall the rubber block over the power supply
conductors and install the wiring box cover being careful not to pinch the O-ring. Screw torque
is specified in the Appendix. See figure 8.
For wiring diagrams 5A and 5B, you will note that there is a small 2-pole terminal block in the
wiring box. This is the thermistor circuit. Proceed to Thermistor Wiring.
Figure 8. Wiring Block Assembly
Figure 7. Terminal Block Hardware Installation
Secure the wire connectors and the shorting bars to the terminal block in the positions shown
on the wiring diagram using the hardware provided. It is essential that the hardware be
positioned as shown in Figure 7.
Note that the closed loop wire connectors provided on the power supply cord are positioned
between the two flat washers. A drop or two of thread sealant such as ocktite is recommended.
Do not use permanent thread sealant because the terminal block will be damaged should you
wish to remove and replace the power supply cord. The terminal block nuts should not be over
tightened since the possibility of damaging the plastic insulating body is high. Reference table
VI in the Appendix for torque values. Make the connections hand-tight followed by a ¼ turn
but never put a ratchet on these nuts.

Thermistor Wiring
Electric vibrators with Diagram 5A and 5B have thermistor circuits installed in the winding.
These devices are intended to protect the winding from over-temperature. Connect the
thermistors to the motor starter using a thermistor control module such as Siemens 3RN1012-
1CK00. Never apply line voltage to the thermistor circuit. It is a low voltage +/- 5V dc circuit.
The thermistor control module is connected to the motor starter control circuit which commonly
operates at 120 Vac. Follow the wiring diagram provided with the thermistor control module.
The thermistors are our Item No. 0539503 and are rated 130°C. There are three PTC thermistors
wired in series that are installed in the vibrator winding and connected to blue or grey leads.
These leads are secured to the small 2-pole terminal block mounted in the wiring box.
To assemble the thermistor cord, remove the threaded metal plug assembled in the side wall of
the wiring box and install a M20 cord grip (our Item No. 0511596). Select a cord type that has
a voltage rating not less than the power supply voltage, that has a minimum temperature rating
of 105°C, and that has an overall jacket diameter within the range specified in Table III. This
table also details the cord provided by the factory for reference. We recommend Coleman black
portable cord SEOOW Seoprene rated 600 V and 105°C. Coleman Cable Inc. can be reached by
phone at 847-672-2300 or at www.colemancable.com. Italvibras USA also stocks the Coleman
cable.
Trim the cord by removing the jacket exposing the conductors for approx. 6 in. Be careful not
to cut the conductor wire insulation. oosen the compression nut from the cord fitting
assembled to the side wall of the wiring box on the electric vibrator. Position the compression
nut on the cord and insert the cord through the opening in the side wall of the wiring
compartment. Position the jacket of the cord approx. ½ in beyond the inside wall of the wiring
box wall and secure the compression nut by threading it to a position equal to the “Distance
Between Flats” noted in Table III. Reference figure 5 which pictorially defines “Distance
Between Flats”.
Trim the conductors within the wiring box leaving plenty of slack. Next, strip the conductor
insulation for ¼ in. to 3/8 in. The conductors should be neatly arranged on the floor of the
wiring box. The wires should not cross over each other. Secure the wires to the 2-pole terminal
block by tightening the compression screws. Reinstall the rubber block over the power supply
and thermistor circuit conductors and install the wiring box cover being careful not to pinch the
O-ring. Screw torque is specified in the Appendix. Reference figure 8.
Grounding & Bonding
The electric vibrator must be grounded using the ground wire
provided in the cord. The ground wire shall be connected to a
closed loop wire connector which is then connected to the ground
terminal located within the wiring box (See figure 6). The ground
terminal is identified by the international symbol.
It may be necessary to bond the electric vibrator to ground using the external ground screw
as shown in figure 9. The external ground terminal is identified by the international symbol.
Use a wire size no smaller than the internal ground wire.
GROUND

Overload, Short-Circuit & Ground-Fault Protection
In the USA, The National Electrical Code, NFPA 70, and all applicable local codes, govern how
to properly size, select and install overload protection (sometimes called heaters) and short-
circuit and ground-fault protection (fuses or circuit breakers). Proper selection and installation
of these devices is required and essential for not only protection of the electric vibrator and the
power supply circuit but also for protection of personnel.
If the overload or short-circuit and ground fault protection operate, have qualified personnel
locate and fix the problem before resetting.
When operating two electric vibrators, the vibrators should be controlled with a single motor
starter that has overload protection dedicated to each electric vibrator. The overloads shall be
electrically interlocked such that should there be a fault with one electric vibrator, both electric
vibrators will be de-energized.
Variable Frequency Inverter
The electric vibrators may be supplied with a variable frequency inverter. Never operate the
vibrators above the maximum frequency noted on the nameplate. If operating two vibrators,
use one variable frequency inverter along with overload protection dedicated to each electric
vibrator. The overloads shall be electrically interlocked such that should there be a fault with
one electric vibrator, both electric vibrators will be de-energized.
The nameplate current should never be exceeded throughout the entire frequency range.

Eccentric Weight Adjustment
The eccentric weights may be adjusted to produce the desired centrifugal force output. It is
always best to operate the electric vibrator at the lowest weight setting that produces the desired
result. This will result in lower energy expense and extend the bearing life. The factory setting
is 50% which would result in 50% of the centrifugal force noted on the nameplate. To adjust the
force output, lockout/tag out the electric vibrator. Remove each weight cover and set it and the
screws, washers and O-rings aside. The outer adjustable weight clamping screw or the shaft nut
may be loosened and then the adjustable weights may be rotated to the desired position.
Reference Figure 10.
The eccentric weights must be adjusted to mirror images of each other at the same setting
number as shown in Figure 11.
Properly torque the clamping screw or shaft nut to secure the weights in position. Torque values
are outlined in the Appendix. Reinstall the weight covers making sure not to pinch the O-rings.

12
Eccentric Weight Adjustment Cont.
Check shaft rotation before replacing weight covers. Start vibrator for 1 second, stop and
lockout/tag out. Observe direction of rotation. If desired to reverse the direction of rotation,
switch two of the three power supply leads in the wiring box or at the motor starter for 3-phase
electric vibrators. For 1-phase electric vibrators, refer to the wiring diagram for changing the
direction of shaft rotation.
Replace weight covers using screws and washers being careful not to pinch the O-rings. The
screw torque is outlined in the Appendix. Never operate the electric vibrator without weight
covers in place. They provide a degree of protection for the bearings and a shield for the rotating
eccentric weights. Always replace broken weight covers immediately. Do not operate electric
vibrator with weight covers removed or with damaged weight covers.
Starting Up
After making sure that the power supply voltage matches the voltage marked on the nameplate,
that the mounting bolts are properly secured, that all covers are in place and secured, and that
the motor starter is properly installed and adjusted, turn the electric vibrator on. Excessive
noise would indicate a problem but slight bearing noise is normal due to the type of bearing
used. After a few hours of operation, check each line current and verify that it does not exceed
nameplate current. If the line current exceeds the nameplate current, then the mount needs to
stiffened, the vibrator weights need to be reduced or the vibrator needs to be moved to a more
rigid location. Never operate the vibrator above nameplate current.
After the first 8 hours of operation, check the line current to make sure that it does not exceed
nameplate and check mounting bolt torque. See MOUNTING HARDWARE AND TORQUE.

Electric Vibrator ubrication
All electric vibrators are lubricated at the factory. If there are no external grease fittings, then
the vibrator construction is lubricated for life. No grease ever need be added to these electric
vibrators. If external grease fittings are provided, then it is intended that the bearings be
periodically lubricated. The lubrication schedule is outlined in Table IV.
ubricate every 2000 hours unless specified otherwise.

Electric Vibrator ubrication Cont.
The lubrication frequency is every 2000 hours of operation unless specified otherwise in the
table. There is an exception - 3600 rpm electric vibrators operating continuously or for long
periods of time should be lubricated in ½ the time specified using ½ the grease volume
specified. For all other vibrators, follow the table except when the operating temperature
exceeds 90°C. If the operating temperature exceeds 90°C, reduce the lubrication frequency and
lubrication volume by 50% for every 10°C increment above 90°C. If the electric vibrator
operating temperature exceeds 100°C, contact Italvibras USA by phone at 815-872-1350. The
electric vibrator should never operate above 120°C.
When adding grease through the grease fitting, make sure to clean the fitting so as not to
introduce dirt into the bearing. Add the specified amount of grease. Experiment with your
grease gun to determine how many grams are introduced with each pump. Never over-grease
a bearing since this will damage the bearing and cause high operating temperature.
Always use the correct grease. Never mix greases. Use Kluber NBU 15 grease in all MVSI 36
electric vibrators. All other electric vibrators are lubricated with Kluber NBU 8EP grease. Kluber
grease may be purchased direct from Kluber ubrication by calling 800-447-2238. Italvibras
USA also stocks the Kluber grease.

Electric Vibrator Repair
If the electric vibrator needs repair, contact Italvibras USA at 815-872-1350 for instructions. Most
electric motor repair shops are not trained to repair our industrial electric vibrators. We
recommend that they be returned to the service center located in Princeton, I . Attempting to
repair the electric vibrator or replace the bearings will void the warranty.
Electric Vibrator Maintenance
Every quarter, we recommend a thorough inspection of the electric vibrator. After lockout/tag
out, do the following:
1.) Inspect the cord for any visible damage or wear. Replace the cord if there are any
signs of damage or wear. This holds true for both the power supply cord and the
thermistor circuit cord.
2.) Remove the wiring box cover and inspect for any foreign matter or liquid.
Vacuum any foreign matter. If wet, remove electric vibrator from service and
have the ground insulation tested by a trained, qualified and licensed technician.
3.) Before replacing the wiring box cover, make sure the electrical connections are
tight (do not over-tighten) and inspect the cover O-ring and rubber compression
block. If the O-ring or rubber compression block is damaged or if they have lost
their compression set, replace them.
4.) Remove each weight cover and inspect for foreign matter. Vacuum if necessary.
Replace O-rings if they are damaged or if they have lost their compression set.
5.) Check the mounting bolt torque.
6.) Replace any broken parts.
