1.0 General
The controllers of the production series SOR are microprocessor-controlled
devices for the adjustment of the transport quantity for oscillating conveyors.
The devices generate a power supply independent of the output frequency
for the conveyor so that a precise tuning of the springs is not necessary.
Due to the sinusoidal form of the output signal, a smooth running condition
of the conveyor is achieved. The adjusted output frequency corresponds to
the mechanical oscillation frequency of the conveyor. The optimal oscillation
frequency is determined, and it is set up by means of the control panel. For
normal operation of the oscillating conveyor, the frequency then remains
constant, and the adjustment of the conveyor capacity corresponds to the
level of the output voltage.
Special Characteristics:
Supply voltage independent, adjustable output frequency
Constant conveyor capacity even with supply voltage variations
External release input
2.0 Function
The operation of the device is achieved by means of a control panel on the front plate (Keys and LED
display). All adjustments can be made by means of this control panel. The setup of the parameters is
achieved by means of a control menu that is accessable after the input of an operator code. In the chap-
ter “Adjustment“, the function of the control menu is explained in detail.
In the normal operating mode, the rated value of the conveyor capacity is displayed in percent on the LED
display. In the programming mode, the corresponding dimensions corresponding to the setup instructions
are to be used. Modified setup values are permanently stored either when the programming mode is ex-
ited or when no key is actuated within 30 seconds.

•Output connection socket for connecting the conveyor.
•Plug connection for connecting a release signal.

8.1 Adjustment Procedure
When depressing the arrow keys, a quick depression of the key will increase or decrease the display by
one place (one or ten), respectively. If the key remains depressed, after the next full decade the display
changes by decades.
In order to prevent accidental or unauthorized adjustment, the adjustment parameters in operating menus
are secured via operator codes. To access the operating menus, an operator code must be entered. Dif-
ferent operator codes (functional depth) are available.
Modified adjustment values are only permanently stored either when the programming mode is
exited or after 60 seconds have elapsed with no key depression.

9.0 Placing in Operation
9.1 Preliminary Measures
•Check whether the local supply power is compatible with that of the device (refer to name plate) and
that the connection value of the conveyor is within the allowable power range.
•Connect controller according to the delivered connection schematic
•Set rated value to zero
•Turn off release (as far as relevant)
The controller is now basically functional and can be switched on (power, release).
Notice
With the control device described herein, it is possible to adjust the resonant frequency
of the connected conveyor. Because in this case even a slight rated-value preset can
result in the full amplitude oscillations of the conveyor, one must be especially careful to
prevent damage to the conveyor due to the limiting operation of the magnet.
The range of the resonant frequency is practically without feedback of the acceleration, but would not be
useful anyway, since the conveyor can be neither used under load nor would it be controllable. Therefore,
a certain frequency interval from the resonant frequency must be adjusted. The frequency interval can be
under as well as over the resonant frequency.
Resonant frequencies: Due to the construction of the spring-mass system of the conveyor, the system
can resonate at a number of oscillation frequencies. The additional resonance points are at a multiple of
the desired frequency. In critical cases, the automatic frequency search cannot recognize them; the fre-
quency must then possibly be set by hand.
9.2 Working Frequency of the Built-in Magnets
Because at small frequency adjustments the current flowing through the magnet may possibly increase,
by the first usage of the current in the magnet circuit the current should be checked with an effective
value meter, and the warmth developing in the magnet should be monitored.
In order to prevent an unduly high current passing through the magnet and the possible overloading of
the magnet, it must be observed that the magnets also operate within the allowable working frequency
range.
9.3 Measurement of the Output Voltage and the Output Current
Because there is an electronic converter with pulse amplitude modulated switching signals at the device
output, the voltage and current values cannot be measured with a conventional meter. To measure these
values, effective value measurement devices must be used; for example, an iron vane instrument (analog
meter). It is recommended that analog instruments be used, because electronic multi-meters will not indi-
cate reliable value readings in this case.
9.4 Restore Rated Value
If, after the adjustment process, the device is found to be out of its allowed state, for example limit opera-
tion or an excessively high current flow which necessitates a quick main power switch-off, then by the
next power on operation, the adjusted rated value can be reset as follows:
With device still switched off, depress key and then switch on the main power switch.
By this procedure, the previously set rated-value for the oscillation amplitude will be set to zero. Now, the
rated-value can be again increased or the frequency adjustment can be changed, among other possible
modifications.

10.0 Adjustment
Depressing the programmer key “P” initializes each type of setup.
1. Depress “P key”.
2. With arrow keys, scroll to desired code number.
3. Depress “P Key”. The first menu point will appear. If necessary, search further for the desired menu
point with the “P key” (scrolling).
4. With arrow keys, make the selection on the selected menu point.
5. Scroll with the “P key” to the next menu point, or scroll to the end of the menu, until the rated-value
again appears on the display.
6. The menu can also be directly exited, and return to the normal operation is achieved, by depressing
the “P key” longer (5 sec.).
