General Description of the Device
Power Unit
The SV3-1-8Z is a control device for oscillation conveyor drives with electromagnets
and works according to the TRIAC-phase angle control principle for the amplitude
limitation. Three conveying devices can be connected.
Essentially there are two operation modes:
•The full-wave control with 100 oscillations per second at 50 Hz mains
frequency or 120 oscillations per second at 60 Hz mains frequency
•and the half-wave control with 50 oscillations per second at 50 Hz mains
frequency or 60 oscillations per second at 60 Hz mains frequency.
In spite of its very compact construction design the control device SV3-1-8Z covers
the performance range that is usual with vibration feeding devices. As standard finish
the device is equipped with soft start and soft run-out, which can both be adapted at
any time to the connected oscillation conveyor drive.
By means of the external, potential-free control input 10 - 30V AC or DC, the
SV3-1-8Z can be enabled or disabled. This is very favorable in the case of
applications with frequent switching operations (e.g. level control), because the
control device doesn’t have to be switched via the mains voltage.
The set-point adjustment of the conveying performance is done by means of a
potentiometer, which is accessible from the outside.
An electronic current control prevents a possible overload of the control device and
the conveyor system.
Three status LEDs inform at any time about the current state of the SV3-1-8Z.
Within the indicated limit values there is no setting required for the mains voltage and
mains frequency.
Power supply
The SV3-1-8Z disposes of a switch-controlled 24V DC power pack. It is used for the
supply the internal time function elements, the connected proximity switches and the
outputs (blast air, control output). The power pack is short circuit-proof and can
supply current of max. 1,5A.
Time function elements
The integrated time function elements have an extensive logic (see page 12). A total
of 11 times is available enabling the realization of different functions. These times
can be set from 0,0 to 25,0 seconds.
