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).
