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.

RESONANCE 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.

DEVICE DESCRIPTION
Using a variable frequency power supply the optimisation of the vibrating system may result
very easy because the natural frequency of the controlled device can be easily tuned.
Because this tuning may be executed with system running, in few minutes the optimal
frequency may be found.
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 through fairleads plus terminals box (for power supply and
commands) and 4 poles connector (for vibrator).
The mains supply is disjointed by a breaker and is protected with fuses inside the box.
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).
The vibration frequency is selected through 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).
Overloads are limited electronically (with autoreset) and are signaled from a red led.
The power supply is shipped with autostart on power-on (switch SW2 on front panel = up)
and voltage reference from potentiometer on front panel (switch SW3 on front panel = up).

Note: The guts of the vibrator must be grounded with a appropriate wire.
Before feeding 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 I1 is in OFF position
•Put the potentiometer P3 at about 20%
•Verify switch SW2 (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 SW3 (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 P1 (MIN)is rotated fully counterclockwise and if the trimmer
P2 (MAX) is rotated fully clockwise
•Verify that all connections are fastened
•Put rotating switches SW1 at 050.0 if a output frequency of 50.0 Hz is required
•Connect the mains (230 Vac) via PC1 cable (or schuko plug)
•Close mains switch I1; if start command is active the vibrator will be supplied at the
frequency selected with rotating switches SW1 (50 Hz) and at the voltage defined
from potentiometer P3.
In practice, the search of the resonance frequency is made by checking the effects on the
product feeding obtained by regulating the selectors SW1 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 SW1
which determines the resonance condition.
Then, after having reached it increase (or decrease) the potentiometer value P3 to obtain the
required vibration level.
During the research stage it is suitable that the potentiometer P3 remains at 20% of the
end of scale.
If, increasing the potentiometer P3 value, the green led DL1 switches off whereas the red one
DL2 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.

digisystem srl (e-mail [email protected] ) we will help you.
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 I1 off and disconnect mains cable
Remove the knob (take the lid off and unlose the screw or nut), unlose the nut of the
potentiometer and the four screws X3 on the panel.

If voltage reference is coming from potentiometer 10K located on front panel, the
switch SW3 (yellow) must be ON (lever up);
The power supply is delivered with this switch on.
If voltage reference is coming from external voltage generator, the switch SW3 (yellow)
must be OFF (lever down) connect 0V at pin 6 and reference at pin 8.
If voltage reference is coming from external potentiometer 10K, the switch SW3
(yellow) must be OFF (lever down), the potentiometer sliding contact must be connected to
pin 8, the CW to pin 5 and the CCW to pin 6.
A switch (SW2 red) on front panel selects automatic or remote start/stop; the switch
ON selects start at power-on, the switch OFF enables start from external command. The
power supply is delivered with this switch ON.
The start-stop control with one external sensor (photocell or other type of sensor) is
available a supply (18 V 50 mA not stabilized).
PNP Sensor: connect supply of sensor between pins 1 ( +18V ) and 4 ( 0V ), connect signal of
sensor at pin 3.
