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)
