Introduction

The vibrators power supply has been designed to keep in vibration the feeded system

giving it the necessary energy in the exact moment it is 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 much as possible the resonance condition, the manufacturer of this

feeding system is obliged to do many adjustments on the springset supporting the holder 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 dipwitch SW2 placed on the card.

Having the possibility to adjust the feeding frequency to the springset the

improvements reached are immediately verifiable.

This device proved utility also after the first installation.

We could test that as the time went by the springset changed its elasticity owing to

phenomenons linked to the enervation of the material.

It is possible to keep unchanged the system performances by the years.

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.

Chapter 1: Device description.

The vibrators power supply is made up from a card with electronic components, a

aluminium cover and a plastic bearing.

On the electronic card there are (in addition to integrated circuits):

-  3 diagnostic leds,

-  a dip-switch SW2 (8 switch) to select the output frequency,

-  a dip-switch SW1 (4 switch) to select the maximum output current,

-  a jumper H1 to select the start/stop logic,

-  a terminal box to connect mains, vibrator and start/stop command.

With reference to the drawing at the bottom of this manual, you will locate these

components.

Chapter 2: Device opening .

To accede to the card on which are placed the setting gears and diagnostic leds, you

have to switch off the power supply, wait at least 5 minutes before removing the cover

(presence of residuary energy on capacitors,  danger of strike), unscrew the 2screws which fix the aluminium box to the card.

Chapter 3: Device installation.

•  Remove aluminium cover (unscrew the 2 screws on front of cover),

•  Locate the dip-switch SW2 (8 switches),

•  Set the desired output frequency (see table associating dip-switches to outputfrequency),

•  Locate the dip-switch SW1 (4 switches),

•  Set the desired maximum output current supply (see table associating dip-switches tocurrent),

•  Connect the load, power, and signal wires to terminal box as suggested in chapter 6,

•  Reassemble the cover and connect it to ground via the brass screw,

•  Close external power supply switch,

•  Set the external voltage reference at about 2 volts,

•  The vibrator should vibrate slowly;

The load will be feeded at the frequency defined by the dip switch SW2 and at the

voltage defined by the external reference.

Increasing the external voltage reference the amplitude of vibration will increase.

If, increasing the voltage reference the vibrator stops, it means that the device is

in overload; decrease the reference value and the power supply will automaticallyreset the overload condition.

Chapter 4: settings.

In case of device replacement report on the new device the settings of the

previous one.

The device is delivered with default settings and in case of replacement of the device

installed with a new one we recommend to report the settings previously set.Jumper H1:  the jumper position in connection with the entry of the terminal box

states the start/stop condition of the device.

•  With (H1) in position 1 the device is normally in motion. The stop  condition isobtained with the active presence of the start/stop signal.

•  With (H1) in position 2 the device is normally in stop. The start condition isobtained with the active presence of the start/stop signal.

The default setting of H1 is in position 1.

Dip switch SW1: the configuration of the dip switch states the highest delivering

current and has the purpose to protect the load feeded.

In the following table there are the current limit values relating to the dip-switch settings.

SW1 CURRENT

1 2 3 4 (amperes)

on on on on 0,13

off on on on 0,27

on off on on 0,47

off off on on 0,67

off off on off 4,66

on on off off 5,59

off on off off 5,73

on off off off 5,86

off off off off 6,00

With all the switches in off (default setting) the device delivers the maximum current.

After having reached the set limit, the device stops to feed the load.

After few seconds, the device automatically restarts feeding the load again.

If the condition causing the anomalous current input is not removed, the device will

continuously switch from start to stop.

After having checked the input current data required from the vibrator manufacturer,

set the current with reference to the corresponding value.

In case of replacement of a device report on the new one the previous settings.

Dip switch SW2: the configuration of these dip switches states the output frequency

and should be selected near the frequency required by the vibrator manufacturer.

The output frequency is not affected from input frequency.

Chapter 5: Troubleshooting

In this chapter we want to help the user to solve the most common problems by

explaining the condition of the signal gears placed on the frontal panel.

If the problem continue also after having checked what we are going to suggest, we

recommend to send a e-mail to our technical assistance info@digisystemsrl.itThere are 3 leds that you can see removing the aluminium cover; see in chapter 2

instructions to open device.

Condition of insufficient feeding (L1 = off, L2 = off, L3 = off).

Check in succession the following points:

1. Voltage of the power supply (230 Vca)

2. A correct connection of the terminal box

3. Fuses condition.

Condition of wrong signalling (L1 = off, L2 = on, L3 = off).

1. Check the integrity of the lamp (L1).

Condition of standby (L1 = on, L2 = off, L3 = off).

The device is ready and is waiting for the start command.

Check in succession the following points:

1. Check jumper (H1), refer to Chapter 4 to determine the start/stop condition of the

device.

2. Repeatedly, start and stop the motion control and check the led (L2) condition.

The correct operation foresees that the led switches on when the start command is

detected.

Condition of normal running (L1 = on, L2 = on, L3 = off).

If the load is not correctly feeded, check the following points in succession:

1. A correct connecting of the plug M1

2. A correct setting of the dip switches SW2

3. A correct setting of the voltage reference (from external potentiometer or PLC)

Block condition owing to current overload (L1 = on, L2 = off, L3 = on).The device is required to deliver a current which is higher than the limit value set by

the dip switch SW1 placed inside the device.

Turn counterclockwise the external potentiometer or decrease reference voltage to

obtain that the led L3 is always off.

If you want to change the set current limit make reference to Chapter 4.

Anomalous condition (L1 = on, L2 = on, L3 = on).

Probably the device is damaged.

Contact our technical assistance (e-mail info@digisystemsrl.it).
