This assembly instruction refers to AViTEQ impact vibrators of the series SR… that
are operated with an AViTEQ magnetic vibrator.
Impact vibrators shall improve the emptying of hoppers that are filled with bulk
materials and avoid plugging, caking, or bridging. This is achieved by directional shock
pulses that stimulate the hopper wall, generated by the impact vibrator.
Please also observe the effective operating manual for the AViTEQ magnetic vibrators !

When the unit is connected to the mains, a lethal voltage is present inside the
controller and the terminal box of the magnetic vibrator. Touching electrically live
components can be lethal! Before switching on mains power, ensure that no live
parts can be touched, the cover of the terminal box is closed and that all cable
glands and insulations are undamaged!

------------------------------------------------------------------------------------------------------------------------------------
Inadequate installation may cause the impact vibrator or the magnetic vibrator to fall
down possibly causing perilous injuries! Ensure that the impact vibrator and the
magnetic vibrator are bolted on tight to the supporting construction and take
appropriate steps to ensure that the units cannot fall down! Remaining under the
impact vibrator is not allowed!

Impact vibrators should only be operated periodically to avoid compacting the bulk
material inside the hopper. Further, only operate the impact vibrator while the outlet
of the hopper is opened and material can be discharged. The maximum shaking
effect arises directly after switching on the drive. Due to this, even a short operation
time of some seconds will help the material to flow out of the hopper. The necessary
operation time (e.g. 8 seconds ON and 12 seconds OFF) ought to be found out by
carrying out tests.
Basically the impact vibrator should only be operated with the impact force (working
stroke) that is just effective enough to achieve the desired effect.
------------------------------------------------------------------------------------------------------------------------------------
N

------------------------------------------------------------------------------------------------------------------------------------
Depending on the construction of the hopper and the acoustic properties of the
material inside the hopper as well as the degree of strength of the impact, the sound
pressure level of the operational impact vibrator may lie in the range of 95 up to 100
dB(A) . It is in the operator’s responsibility to assure that appropriate measures are met
at the operating location. For example the use of “personal protective equipment” (ear
protection)!

Device Specification
The construction concept of the impact vibrator with electromagnetic drive is shown
in the figure below. The magnetic vibrator is normally operated together with a
controller.
Together with the vibrator plate (3) the magnetic vibrator (1) forms a two-mass
oscillation system. The vibrator plate is linked to the base support (6) by rubber pads (2).
The operating magnetic vibrator generates a linear movement of the impact bolt (4).
During operation the impact bolt hits against the impact plate (5) and generates a shock
pulse that is transmitted into the hopper wall the impact vibrator is tightened to.

Installation
Installation location and clamping area
To assure an effective operation of
the impact vibrator, please select the
ideal installation location. Hoppers
that tend to plugging or bridging
normally show a good emptying, if
the impact vibrator is mounted at
about 1/3 of the height of the conical
hopper (...see Figure 1).
We recommend using a rigid plate or
steel profile with corresponding holes
for the fixing screws in the case of
hoppers made out of sheet steel.
In the case of thick-walled and stiff
hoppers made out of steel or
concrete, a steel plate is required
that rests on steel or rubber strips at
its edges ( ...see Figure 2).
The installation of the impact
vibrator is described on the following
page. The electrical connexion to the
a.c. mains is described in the
appropriate operating manual for the
magnetic vibrator.

Assembly preparations
Choose the correct screws for fixing the impact vibrator. The particular screw size is
indicated in the following table. The recommended length of engagement is valid for
threaded holes and a support structure made of steel. Only choose screws with a
bolt quality of at least 8.8 and clean the screw thread from oil deposits.
Table 1 Fixing screws
In the case of threaded holes we recommend to use Loctite 245 for securing the
screws.

Danger of crushing! Use appropriate hoisting devices for transporting the impact
vibrator and avoid unintended swinging of the unit on the hoist during the transport.
Further prevent the impact vibrator from falling down by securing it appropriately.
------------------------------------------------------------------------------------------------------------------------------------
Screw the impact vibrator onto the hopper. Tighten the fixing screws with the
torque indicated in the following table.

In the case of through holes, each nut must be secured by a locknut. If it is not
possible to use such a locknut, the nut must be secured using Loctite, just as in the
case of threaded holes.

!
------------------------------------------------------------------------------------------------------------------------------------
It is totally prohibited that the current consumption of the magnetic vibrator exceeds
the value of the nominal current specified on the type label, because this may lead to
destroying the magnetic vibrator.
------------------------------------------------------------------------------------------------------------------------------------
We recommend to fill the hopper prior to commissioning and to keep the outlet
opened.
Loosen the locknut at the impact bolt and screw the impact bolt into the vibrator plate
until an air gap of some 5 mm exists between the impact bolt and the impact plate.

------------------------------------------------------------------------------------------------------------------------------------
Danger of crushing! Danger of crushing the fingers in the area of the air gap
between the impact bolt and the impact plate during operation.
------------------------------------------------------------------------------------------------------------------------------------
The commissioning procedure must be carried out using the lowest working stroke:
Turn the vibration-width adjuster (potentiometer) on the controller counter clockwise
till you reach the end stop (scale value of 0) or, if you use an external command
value, set the lowest command value. Now switch on the controller.
Listen for any hammering noises that indicate the collision mode.

------------------------------------------------------------------------------------------------------------------------------------
It is not allowed to operate the magnetic vibrator if hammering noises exist! Collision
mode will lead to destroying the magnetic vibrator. Please ask us in the case of doubt.
------------------------------------------------------------------------------------------------------------------------------------
Slowly increase the working stroke by gradually turning the vibration-width adjuster
(potentiometer) or by increasing the external command value, until the maximum
value has been reached.
If hammering noises occur, switch off the unit and check the cause. By measuring
the current on the terminals of the appropriate controller, you can check the related
value.

Short circuit or danger of electrocution during the following measurements! Observe
the safety regulations when measuring voltage-carrying components! Take
appropriate measures to prevent contact with voltage-carrying components.
------------------------------------------------------------------------------------------------------------------------------------
The current that is shown on the type label must not be exceeded! Additionally you
can measure the vibrator voltage and compare it with the value that is shown on the
appropriate characteristics curve data sheet.

Only use meters which display the root mean square value for measuring the voltage
and the current (moving iron instrument or „true RMS“). Other measuring devices
would not produce relevant measurements when measuring the non-sinusoidal voltage
or current curve. For digital measuring devices, select a measuring range of  750 V !
------------------------------------------------------------------------------------------------------------------------------------
If no problems appeared while commissioning, please adjust the impact bolt as
follows. Make sure that the impact vibrator is switched off before carrying out any
adjustment work. Unscrew the impact bolt until it just starts touching the impact
plate. Then secure the impact bolt with the appropriate locknut.
Finally, please check the function of the impact vibrator while discharging the
hopper: Is the material discharged uniformly?
N
NO OT TE E
------------------------------------------------------------------------------------------------------------------------------------
The impact force can be modified by varying the working stroke with the appropriate
controller. Basically the impact vibrator should only be operated with the impact
force (working stroke) that is just effective enough to achieve the desired effect.
------------------------------------------------------------------------------------------------------------------------------------
Did problems appear while commissioning or do you have any questions, give us a
call. We’ll be glad to help you.
