Attention
This warning triangle marks the safety instructions. Non-observance of these warnings can result in seri-
ous or fatal injuries!
Dangers occuring at the machine
The most dangerous parts of the machine are the electrical installations of the vibratory bowl feeder. In
case the vibratory bowl feeder becomes very wet, there is the danger of an electric shock!
Make sure that the protector ground of the electric power supply is in perfect condition!
Operation of the vibratory bowl feeder without trim panel is strictly prohibited!
Proper use
The intended use of the vibratory bowl feeder is the actuation of sorting machines. These sorting machines
are used for sorting and feeding correctly positioned mass-produced parts, as well as for the proportioned
feeding of bulk material.
Using the machine for other purposes than the above mentioned, eg. as vibrating screen or in material test-
ing, is considered not to be the intended use.
The intended use also includes the observance of the operating and servicing instructions.
Please take the technical data of your vibratory bowl feeder from the table "technical data" (see page 1-2).
Make sure that the connected load of the vibratory bowl feeder, control unit and power supply corresponds to
each other.
Notice
The vibratory bowl feeder may only be operated in perfect condition!
The vibratory bowl feeder may only be operated in the configuration drive unit, control unit and bowl, as speci-
fied by the manufacturer.
The vibtratory bowl feeder may not be operated in the explosive or wet area.
No additional loads may act upon the vibratory bowl feeder, apart from the bulk material, for which the special
type is designed.
Attention
It is strictly prohibited to put any safety devices out of operation!
Demands on the user
For all activities (operation, maintenance, repair, etc.) the details of the operating instructions must be
observed.
The operator has to refrain from any working method which would impair the safety of the vibratory bowl
feeder.
The operator has to take care that only authorized personnel works at the vibratory bowl feeder.
The operator is obliged to inform the operator immediately about any changed conditions at the vibratory

Attention:
Since the electromaget-field may have an impact on persons arrying pacemakers it is recommended to
keep a minimum distance of 25 cm.
Noise emission
The noise level at the place of operation depends on the total equipment and the material to be sorted. The
determination of the noise level according to the EC-Regulations "Machinery" can therefore only be carried
out at the place of operation.
If the noise level at the place of operation exceeds the limit permitted, noise protection hoods may be used,
which we offer as accessory parts (see catalogue).
Standards and regulations
The device was built according to the following standards and regulations:
Low voltage directive 2014/35/EU
EMC directive 2014/30/EU
We assume that our product is to be
integrated in a fixed machine. The provisions of the EMC directive 2014/30/EU has to be considered by the
user.
Applied harmonized Standards

3 Construction and function of the
vibratory bowl feeder
Vibratory bowl feeders are used for the actuation of sorting machines. The actuation takes place by electro-
magnets. The following schematic diagram shows the function of a vibratory bowl feeder:
The drive magnet D is firmly connected with the counter-mass F. When current passes the drive magnet, it
exerts power on armature E. The power is transmitted to bowl A, which is supported by the spring assembly
C. The moving direction of the bowl is determined by the angle of the spring assemblies.
Owing to the vibrations the material to be conveyed is shortly lifted off the conveyor belt (helix of the bowl)
and it carries out little jumps (microjumps). The jump direction is in a right angle to the level of the spring
assemblies.
The drive magnet achieves its maximum magnetic force twice during a period of the alternating current. Con-
sequently the vibration frequency corresponds to the double mains frequency.
For heavy sorting installations a lower frequency of 50 Hz can be more advantageous.
The vibration frequency of your vibratory bowl feeder results from the last figure of the type designation:
-2: 100 Hz - 6000 vibrations/min.
A = Bowl
B = Material to be conveyed
C = Spring assembly
D = Drive magnet
E = Armature
F = Counter-mass
G = Vibration buffers

A vibratory bowl feeder is a resonant system (spring-mass-system). The result is that the adjustment made at
the plant will rarely meet your requirements. Chapter 5 shows how your vibratory bowl feeder is adapted to
your requirements.
As accessory parts we are offering a spectrum of sorting bowls, which cover a wide range of application. For
special applications individual problem solutions can be manufactured.
Controlling of the vibratory bowl feeder takes place by a low loss electronic control unit. The selection of the
control unit depends on the power consumption of the vibratory bowl feeder. The following table shows the
kind of control units that can be used at the individual vibratory bowl feeders:

Notice
Detailed information on the complete range of control units may please be taken from the operating in-
structions for control units.
All control units have got two main operating elements:
By the mains switch the vibratory bowl feeder is switched on or off.
By the turning knob the conveying capacity of the sorting unit is set.
4 Mounting
The device is completely mounted.
The vibrator has to be screwed on a strong subassembly in a dry room.
Ambient temperature –10° to + 50°C
Ensure that no contact exists between the bowl feeder in operation and other equipments. The bowl feeder is
to be firmly mounted from beneath the fastening threads on a mass of at least
15 –20 Kp.

5 Starting
Preparations
Notice
Ensure that the machine frame (stand, under frame, etc) is connected with the protective conductor
(PE). If necessary, protection earthin must be praided on spot.
Check, whether
the vibratory bowl feeder stands in an isolated position and does not come in contact with a solid body
the sorting bowl is tightly screwed down
the connecting cable of the vibratory bowl feeder is plugged in at the control unit.
Attention
The electric connection of the vibratory bowl feeder may only be made by trained personnel (electri-
cians)! In case modifications are made at the electric connection, it is absolutely necessary to observe
the operating instructions "control units".

Bowl feeder VT-BA-SRC63-100-GB
the available supply voltage (frequency, voltage, power delivery) corresponds to the connecting data of
the control unit (see type plate at the control unit).
Plug in the mains cable of the control unit.
Switch on the control unit with the mains switch.
Notice
At vibratory bowl feeders which are delivered as a completely adjusted system, the optimal conveying
capacity is already set in the factory. It is marked on the scale of the turning knob with a red arrow. In this
case set the turning knob to the marking.
The optimal operative range of the vibratory bowl feeder is at a controller position of 80% at the control unit.
In case of higher deviations
(

15%) a new adjustment must be made. This adjustment is described on the following page.
In the factory the vibratory bowl feeders are approximately adjusted to standard sorting bowls (without sorting
element).
Adjustment
To set the air-gap, lift and lower the magnet coil, which is fastened with a threated pin.
Adjusting the magnet coil:
1. Fit the unit on a solid subsurface
2. Loosen the fixing screw of the magnet coil (Screw is fitted laterally at the counter mass
across the cable outlet)
3. Adjust the air-gap with the height adjusting screw of the magnet coil. This new is found lat-
erally at the counter mass between the cable outlet and fixing new of the coil magnet
4. Tighten the fixing screw
In order to guarantee an optimal sorting behaviour, the vibratory bowl feeder must be adjusted to the con-
crete operating conditions.
The adjustment is made by adding or removing leaf springs and washers.
While the spring fastening screw is loosened, you can see a change in the conveying speed.
The following graphic chart shows the resonance curve of a vibratory bowl feeder:
Notice
The resonant frequency of the vibratory bowl feeder may not correspond to the mains frequency.
Notice
The adjustment is, however, more easy with an electronic frequency converter, which you can buy from
our range of accessory parts.
The vibratory bowl feeder should be adjusted that the required conveying capacity is achieved at a controller
position of approx. 80% at the control unit.
A = Conveying speed
B = Natural frequency of the system
C = Resonance curve (not true to scale)
D = Spring power (number of springs)
