SAFETY INSTRUCTIONS
Before the start-up of the power supply read carefully this instruction manual.
Attention: in order to reduce fire risks, electric shock or accident when carrying out
installation work and making connections please observe the following safety
instructions:
• Install the equipment in a place clean, dry and not subject to vibrations
• Do not use in presence of gas or flammable liquids
• Installation must be made from qualified staff
• Isolate from mains before installation or dismantling work, as well as for fuse changes or
post installation modifications
• The earth connection must be checked, for correct function, after installation
• Before putting into operation check if the local supply voltage conforms the rated voltage
• Verify absence of ground dispersions into the connections between power supply and
vibrator and use shielded cable for this connection
Attention: Hazardous Voltage
If these instructions are not followed serious injury to persons
or damages to things can be caused.

INTRODUCTION
The vibrators power supply has been designed to keep in vibration the feeded system giving it the
necessary energy exactly when required.
The most common application of this device is the feeding of the electro-magnets excitation coils
which are installed in the vibrating system, linear and circular, usually employed as feeding devices
in automation systems.
All the feeders traditionally used supply the load with a fixed frequency depending on power mains.
As we have to fit the springset to the feeding frequency we don’t have satisfactory results.
To approach as soon as possible the resonance condition, the manufacturer of this feeding system is
obliged to do many adjustments on the springset supporting the container of the pieces to feed.
This complicated operation seldom reaches the resonance condition1.
Using the vibrators power supply, to change the feeding frequency in order to reach the resonance
condition, it is sufficient to regulate the 4 rotating switches placed on the front panel.
Having the possibility to adjust the feeding frequency to the springset the improvements
reached are immediately verifiable.
As the regulation above mentioned can be made while the system is in motion, in a few minutes you
can find the best feeding frequency and obtain from the system the best performances.
This device proved utility also after the first installation because as the springset change its elasticity
on the time in consequence of the enervation of the material.
It is possible to keep unchanged the system performances by the years.
DEVICE DESCRIPTION
The vibrators power supply is very compact and easy to install.
With reference to the drawing at the bottom of this manual, it will be very simple to identify the
most important components.
Two holes (diam. 6 mm) will allow to fix the box to the structure which will support the device.
Electrical connections are made with a 9 poles AMP circular connector and with a 9 poles subd type
connector (see options wiring table at page 9).
The mains supply is disjointed by a breaker and is protected with fuses inside the box.
The vibration frequency is selected with 4 rotating selectors located on front panel (the most left
digit are hundreds of Hz, the second are tens, the third are units and the most right are tenths of Hz).
The vibration intensity may be regulated with the potentiometer (the minimum and maximum limits
of potentiometer may be regulated with trimmers MIN e MAX accessible on front panel).
Overloads are limited electronically (by a circuit with autoreset) and are signaled from a red led.
The power supply is shipped with autostart on power-on (switch A3 on front panel = up) and voltage
reference from potentiometer on front panel (switch A6 on front panel = up).
1RESONANCE CONDITION: It is the frequency by which the feeding system delivers the minimum energy to
obtain the maximum vibration: The system is composed by the springset and the container of the products to be
feeded.

The connection wiring is composed by 3 cables (length is 2 meters).
A cable 3 x 0,75 mmq. not shielded for mains input, a cable 3 x 0,5 mmq. shielded for
start/stop command and a cable 3 x 1 mmq. shielded for vibrator.
Note: The guts of the vibrator must be grounded with a appropriate wire.
Before supplyng the device verify that there are not ground dispersions on
wires connecting the power supply to the vibrator; The power supply will be
damaged if one of the two output wires is grounded.

STARTUP
• Verify that mains breaker D2 is in OFF position
• Put the potentiometer A4 at about 20%
• Verify switch A3 (red) lever status (if is up the power supply will start as soon as
supplied, if is down the external start command is required)
• Verify switch A6 (yellow) lever status (if is up the voltage reference is coming from
potentiometer, if is down the external voltage reference is required)
• Verify if the trimmer MIN is rotated fully counterclockwise and if the trimmer MAX is
rotated fully clockwise
• Verify that all connections are fastened
• Put rotating switches A5 at 050.0 if a output frequency of 50.0 Hz is required
• Connect the mains (230 Vac) via D1 connector
• Close mains switch D2; if start command is active the vibrator will be supplied at the
frequency selected with rotating switches A5 (50 Hz) and at the voltage defined from
potentiometer A4
In practice, the search of the resonance frequency is made by checking the effects on the product
feeding obtained by regulating the selectors A5 values.
Usually the resonance frequency is not too far from the rated (for a 50 Hz vibrator should be
between 45 and 55 Hz), but also a little frequency change will determine a significant speed change.
Than, proceed by further guesses until you find the position of the rotating switches A5 which
determines the resonance condition.
Then, after having reached it increase (or decrease) the potentiometer value A4 to obtain the
required vibration level.
During the research stage it is suitable that the potentiometer A4 remains at 20% of the end of
scale.
If, increasing the potentiometer A4 value, the green led L3 switches off whereas the red one L1
switches on and the vibrator stops, it means that the device is in overload; decrease the
potentiometer value and the power supply will automatically reset the overload condition.

OPENING INSTRUCTIONS
As on the electronic card there are some capacitors with high voltage applied (presence of
residuary energy, danger of strike) you must wait at least 4 - 5 minutes after the device is
disconnected from the power supply, before opening the box.
Switch D2 off and disconnect D1
Remove the knob (take the lid off and unlose the screw or nut), unlose the nut of the
potentiometer and the four screws M3 on the panel.
