ELEKTRONIK
1.0 General
The REOVIB MFS 268 range comprises special, adaptable controllers for use with vibratory feeders. The
units generate an output frequency, to drive feeders, that is independent of mains frequency and so exact
tuning with springs is not necessary. The feeders also run quieter because of the sinusoidal output signal.
The adjusted output frequency corresponds to the mechanical vibrating frequency of the feed system.
The optimum frequency setting for a feeder can determined manually or automatically in regulation mode.
Depending on the version, the controller can be used in regulation mode, working in conjunction with an
accelerometer fitted to the feeder, to operate at resonant frequency. In this way a constant component
feed rate that is unaffected by load changes can be achieved. In regulation mode the vibrating frequency
is also dynamically adjusted to compensate for resonant frequency changes caused by load changes. In
normal operating mode (without accelerometer) the feeder remains constant at the set frequency. In both
operating modes the feeder throughput is determined by the output voltage level.
Totally enclosed or panel mounting units can be supplied.
Notable Features:
•Adjustable output frequency, independent of mains fre-
quency
•Adjustable minimum and maximum limits for the frequen-
cy range
•Adjustable current limit for the maximum coil current
•Constant feeder throughput irrespective of mains fluctua-
tions
•Regulation control, with independent frequency search
(resonance)
•On/Off status relay
•Track control
•24 VDC output for operating a solenoid e.g air valve
•Four user setting memory locations
•Optional RS232 or Profibus-DP interface for remote pa-
rameter setting.
2.0 Function
The unit is set up by using the touch panel on the front plate (buttons and LED display). All settings can
be made by using the touch panel and a series of menus. The various parameters can be selected by
entering operator codes. A fuller description of the parameters can be found In the section on settings.
Alternatively, the feeder throughput can adjusted by using an external potentiometer, an external voltage
signal 0...10 V, DC or a current signal 0(4)...20 mA (the chosen option must be selected in menu 003). A
relay with potential free contacts is provided for feeder status indication and this operates in conjunction
with the feeder enable signal. Terminals for these contacts can be found inside the controller.
During normal operation the set point is displayed as a percentage in the LED window. In the program-
ming mode the selected dimension, as described in the setting up instructions, is shown. Changed set-
tings can be stored by leaving the programming mode or automatically saved by not pressing a key for a
period of 100 seconds.
The control units can provide a frequency range from 5…300 Hz, which can be limited by adjustable,
upper and lower frequency limits. The usable adjustment range cannot exceed a ratio of 1:4, i.e. the up-
per frequency limit cannot be more than four times the lower frequency limit. It is possible to have a nar-
rower setting of the limits and this provides a margin of safety against too wide a difference in the vibrat-
ing frequency.
The maximum output current drawn by the coil can be determined by integrated current limiting.
Critical parameters such as the current limit and vibrating frequency range are held under a special ser-
vice menu. This menu cannot be accessed through the normal menu structure and an additional code
number has to be used to gain access. This prevents unauthorised adjustment of these sensitive parame-
ters.
An interface option can be used to provide an RS232 or Fieldbus (Profibus-DP) connection.

2.1 Track control
The output can be
switched ON and OFF
from a track component
sensor, using internal,
adjustable time delays (ton
and toff).
The queue of components
rises above and drops
below the track sensor
position. The controller
output switches on when the sensor cannot detect product and a switch-on time delay has elapsed. The
output is switched off when product is detected and a switch-off time delay has elapsed (FULL displayed
in the LED window). Gaps in the product feed cause resetting of the time delay. The time will always be
precise from the last or first component, respectively. The ON and OFF time delays are set in the pro-
gramming menu. The first decimal point in the display blinks to indicate that an internal timer is running.
An additional “Sensor-Time-out“ timer is started when the feeder switches on. This can be set (30...240
sec.) to switch off the feeder if no product is sensed in the time out period. The status relay indicates that
the feeder is not running and the LED window displays ERROR and SE alternately. This function is op-
tional and must be selected in the Track Settings Menu with function EEn = 1.
2.2 Operating with two speeds (2 set points for coarse/fine switching)
Coarse/Fine control can be used instead of track control (Menu C 003). The second set point is activated
through the same sensor input that is used for track control. Either contacts or a 24 VDC signal can be
used to change the set point from coarse to fine. The second set point is activated, immediately, by apply-
ing a 24 V signal
(The track control function is invalid)
2.3 Control inputs and output
2.3.1 Enable input
External switch or 24 VDC signal voltage.
External control function to switch the power output ON or OFF e.g. Networking of several controllers
from a central PLC.
2.3.2 Sensor input for track control
Sensor for monitoring the queue of components on the track or an input for switching to the second set
point 24 VDC (PNP).
2.3.3 External set point
The feeder amplitude set point can be provided from and external, analog 0...10 V, DC, 0(4)...20 mA, or a
10 kR Potentiometer. Parameter ESP in Menu C003 must be set to I, for an external set point source to
be used.
If a potentiometer is used, must additionally parameter "POT" set to I. (not on 16A IP 20 units).
Setting the minimum output value when external set point = 0:
Before changing the ESP parameter to accept an external set point source, the minimum value can be
adjusted by using the cursor keys, on the front panel, and this will remain when the ESP is changed over
from 0 to I.

8.0 Control elements
8.1 Settings
The six buttons and a LED display found in the
front panel, are used for operating and setting up
the unit. All operating methods and adjustable
parameters can be set up through this panel.
The “I“ and “O“ buttons are used for switching the
unit ON and OFF, however, these do not provide
mains isolation, they simply inhibit the power
semiconductors
The “P“, “F“ and “Cursor Buttons“ are used for
parameter adjustment. Parameters are set by
using menu controls which are called up by enter-
ing operator codes. The functions are described
in greater detail in the section on setting instruc-
tions.
The display value can be increased or decreased
by units, or tenths of units, by a short press of the
cursor buttons. Holding the buttons down will
cause the display to change in units of ten.
To prevent accidental or unauthorized adjustment the adjustment parameters, in the user menus, are
protected. A code must be entered to open the user menus. There are different pass codes for each func-
tion group.
Setting adjustments are automatically saved upon leaving the programming mode or if no button
is pressed for a period of 100 seconds.
All setting routines are commenced by pressing the programming button “P“. The following diagram
should clarify the sequence in which keys are pressed:
1. Press the “P“ key.
2. Select the code number with the cursor keys.
3. Press the “P“ key. This displays the first menu point. The required menu point can be found by re-
peatedly pressing the “P“ key (scrolling).
4. The value in the menu point can be changed with the cursor keys.
5. Scroll to the next menu point or to the end of the menu, which returns the display to the set point val-
ue, by pressing the “P“ key. To exit the menu and return back to the normal display, quickly, depress
the “P“ key for 5 seconds.
6. To return back to the previous position in the menu, press the “F“ key.

9.0 Commissioning
9.1 Assembling position
Please fasten the devices on a vibration-free underground and take care for sufficient air
circulation.
9.2 Preliminary steps
•Check that the unit is correct for the local mains supply (rating plate information) and that it is correct-
ly rated for the feed system.
•Connect the controller according to the connection diagram
•When applications with frequently on and off cycles are required, use the intended enable input. It is
prohibited to open the current circuit with a switch or a contactor while the feeder is running.
9.2.1 Important points
Using the control units described in this document, it is possible to adjust the feed system
that it runs in resonance. In this condition it is possible to obtain excessive output for a very
low set point setting. Therefore extreme care should be taken to avoid causing damage to
the drive coil, through hammering.
In practice it is not possible to run at resonant frequency without accelerometer feedback because the
system would be unstable and uncontrollable. The system must be set safely off resonance i.e. either
above or below the natural frequency.
Resonant frequency: Depending on the spring and mass design of the feeder system it is possible to
have resonance at more than one frequency. These additional resonance points are multiples of the main
frequency. For this reason in critical situations it is possible that the automatic frequency search will not
find true resonance and in such cases the natural frequency must be determined manually.
9.2.1.1 Operating frequency of the feeder coil
It is possible that the current flowing through the coil will increase for a small frequency adjustment. And
so this should be checked with a true RMS instrument for each new application as well as monitoring the
coil for heat build-up.
The coil should be designed for the correct operating frequency to prevent excessive current draw and
the consequential overloading of the coil.
9.2.1.2 Measurement of the output voltage and current
The voltage and current cannot be measured with a regular instrument because the controller output uses
an electronic inverter with a pulse width modulation signal. An effective measuring instrument such as a
moving iron meter (analog) must be used. It is recommended that an analog instrument is used rather
than an electronic multi-meter which will give a misleading reading.
