1.0 INTRODUCTION
The Invicta L Series Vibrators are Heavy Duty Industrial Rotary Electric Vibrators. Their
similarity in appearance to conventional industrial electric motors should not mislead the user into
servicing them as standard electric motors.
The stator frame castings, cylindrical roller bearings, bearing housings, rotors, stators and
fasteners are of special construction and tolerance fits. This is because the Invicta is a "Vibrating
Machine" and only original factory parts should be used. Furthermore, to achieve satisfactory
results, troubleshooting and repairs should be performed by trained personnel experienced with
Invicta Vibrators.
The Hindon facility in Charleston, SC, has personnel fully qualified and is stocked to
perform all required service, retrofit and rebuilding.
• Please read this manual carefully.
• Use only Original Equipment Manufacturer (O.E.M.) parts (including specified bearings).
• Use only personnel trained in the repair of Invicta Vibrators.
As a point of interest, the L Series model designation includes an indication of maximum centrifugal force
output. Actual force is 100 times the centrifugal force figure stated.

2.0 RECEIPT AND STORAGE
Each machine is thoroughly inspected and tested before leaving the factory, and every care
is taken to ensure safe transit to destination. Damage may, however, occur during shipment.
Therefore, the vibrator should be inspected upon receipt and the shaft rotated by hand. Any damage
should be reported immediately to the carrier. Vibrators not intended for immediate use should be
stored in a dry temperate atmosphere, free from vibration. Under these conditions, the machine may
be stored for approximately 18 months.
Extended Storage
For vibrators requiring storage beyond 18 months, please contact Hindon Corporation for
specific instructions.

3.0 INSTALLATION
3.1 Mechanical
Ensure shaft rotates freely by hand prior to mounting. This will require removing one end
cover to access the out-of-balance (O.B.) weights. Unless otherwise requested, vibrators are supplied
with the O.B. weights set to give a maximum centrifugal force output. To adjust O.B. weights to
the required force output, follow these steps and refer to Figure 1.
1) Remove end covers.
2) Adjust inner weights on each side of shaft extension to reduce centrifugal force output while
outer weights remain fixed on the shaft. Please note: For models BL 03-20 out-of-balance
weights can be adjusted by inner or outer weight, provided both ends are adjusted the same.
3) Weights must be adjusted equally on each side of the vibrator. The scale on the inner O.B.
weights is stated as a percentage of the maximum rated centrifugal force (CF) output.
Example: BL 30-25/4 is factory set at a maximum 5500 lbs. CF (i.e., 100 percent O.B.
weight scale). Assume you need to achieve a 3575 lbs. CF output. Adjust the O.B. weights
on each side to 65 percent (0.65 * 5500 = 3575). The percentage scale attached to the inner
O.B. weights allows for an infinite adjustment between the range indicated. Care should be
taken to properly re-torque O.B. weight clamp screws (in accordance with internal fastener
torque values in Table 1).
4) Ensure end cover O-rings are properly positioned on bearing housing flange prior to refit of
end covers. (If O-rings are dry, an application of petroleum jelly or silicone spray will ease
refit of the end covers and reduce the potential of O- ring "pinching").

It is recommended that the fasteners (bolts, nuts and hardened flat washers) be a minimum
of grade 5 and a maximum of grade 8. It is extremely important to follow the guidelines below for
safe and proper vibrator mounting:
1) Vibrator must be mounted upon a flat or machined, rigid base. NOTE: If the base is not flat
or is able to flex under load, the vibrator can come loose.
2) Ensure that no paint or other foreign matter exists on any of the mating surfaces being bolted;
either at the washer seatings or on the vibrator foot or vibrator mounting beams.
3) For all vibrator models, the mounting bolts must be provided with hardened flat washers
under the bolt heads and under the nuts. Ensure that entire outside diameter of washer seats
within the spot facing of the mounting hole.
4) The nuts must be pre-tightened until all the mating surfaces are brought into contact. The
nuts must then be tightened using a torque wrench in accordance with torque values as
detailed in Table 2. (Use a criss-cross pattern for torquing sequence).
5) After approximately 30 minutes of initial vibrator operation, the unit should be switched off
and all mounting bolts checked and re-tightened with a torque wrench to the values stated
in Table 2. After one to two hours of operation, this tightening procedure should again be
repeated. If any loosening of the mounting bolts has occurred during this initial period,
check flatness of mounting plate and vibrator base to ensure a proper "seating" of the two
surfaces.

3.2 Electrical
It is a good policy, prior to vibrator mounting, to measure winding insulation resistance by
meggering; this reading should be greater than 1 megohm. If the winding has become damp, resulting in
an unacceptable megger reading, the stator winding must be thoroughly dried and re-meggered and a
satisfactory reading obtained prior to vibrator installation. In the event of an unacceptable megger reading,
please contact Hindon Corporation directly and advise reading along with vibrator model and serial
number. Most vibrators are dual voltage 230/460 (verify electrical data by reviewing the vibrator
nameplate) and are normally factory configured for 460 Volt operation. For 575 Volt winding “Star”
connection as shown in figure 2 (pg. 5) would apply. Configuring for 230 Volt operation is easily
accomplished by adjustment of the link plates (buss bars) on the terminal block. For specific terminal box
connections, please refer to Figures 2 and 3 on the following page. For details on wiring of thermistors
that are supplied in Invicta models BL 24 – BL 75, please refer to section 3.2.3
3.2.1 Cable Connection
Attach flexible 4-conductor type "SO" cord (allowing for "drip or vibration loop") and
suitable watertight connector to terminal box entry. NOTE: For added safety, electrical power cord must
be installed with sufficient slack to allow vibration, and so that condensation will "drip" from bottom of
loop.
