1General
In this manual, you will find all important information regarding the mounting, connection, setting and
operation of your FS-26E device.
In addition, you will find information as well as important warnings for your safety.
Please observe:
Devices of the FS-26E series are specially adapted frequency converters for the actuation of vibratory
conveyors. The devices generate a mains-independent output frequency for the vibratory conveyor. An
exact tuning of the vibratory conveyor is therefore not required. The vibratory conveyor has smooth
running behaviour due to the sinusoidal output current. The set vibration frequency on the control device
generates twice the vibration frequency on the vibratory conveyor. The optimal vibration frequency for the
transported material is set manually.

2 Application
The electronic frequency converter FS 26 is used for the infinitely variable control of inductive loads,
such as spiral conveyors, linear conveyors and hoppers.
The device works according to the principle of pulse width modulation within the half-waves with
adjustable periods of 5 - 200 Hz; the conveying capacity is adjusted by adjusting the magnet voltage via
the membrane keypad embedded in the housing cover or alternatively selectable via 0-10 V DC, 4-
20 mA or an external 10 kOhm potentiometer in the range of 1V~ up to the maximum output voltage. By
limiting the upper and lower setpoint limits, the optimal specified range can be moved along via the
setpoint.
The amplitude of the sinusoidal output current (upper half-wave) depends on the set period and is
therefore constant. The vibration frequency is set via the keypad as standard.
After switching on the mains voltage, the integrated, adjustable soft start is started and ensures the
output voltage starts up jerk-free up to the set voltage value. A limiter stage limits the load current of the
capacitors to 6 A in the moment of switch-on. Possible switch-on peaks are minimized this way.
Furthermore, both the soft start as well as the soft stop when the output voltage is switched on/off are
activated via the control input and are for increasing and decreasing the conveying capacity with time
control so that ordered bulk material does not change its position again. Both times can be adjusted
separately.
The control inputs allow the device to be switched on and off by another system (PLC, initiator, sensors,
etc.). The control device therefore provides its own supply voltage of +24 V DC. Switching on or off via an
external voltage of + 24 V DC is also possible.
Via the additionally integrated outputs, external devices can be operated or controlled, depending on the
logic specification.
The device provides an input for connecting an acceleration sensor for readjusting the output voltage.
Note
By determining the mains voltage and output current, changes are registered immediately and
compensated for by a controller stage, i.e. the output voltage remains stable. This way, the bulk
material is guaranteed to run smoothly.
Tip
On the control device, small magnets can also be safely operated.

Warning:
Procedure for high voltage test:
L and N must be connected with each other.
Test voltage may not be higher than 1000 V AC.
Every device must be tested separately.
If the above criteria are not complied with, the device could be damaged and the warranty will be
void.
Caution:
The cover of the device is made of plastic. Screwing on the cover with the six countersunk
screws must not be done with force, since otherwise there is a risk of the plastic cracking.

Keypad explanation
The parameters are set by means of a menu structure and by entering an operator code.
In the "Setting instructions", the menu structure and the setting ranges of the parameters, as well as the
function programming, will be explained.
By briefly pressing the arrow key 0 (increase/change) or 1 (decrease/change), the value in the selected
parameter is increased/reduced or changed by one position (ones, tenths or mode). If the one or other
key is kept pressed, it switches to fast mode, and after approx. 1 s to 2x fast mode.
If arrow keys 2 (clockwise rotation) and 3 (counterclockwise rotation) are briefly pressed, it switches
from one parameter to the next. If the one or other key is kept pressed, the parameters are rolled
through.
By briefly pressing the arrow keys 6 (increase) and 7 (decrease), the level structure is changed from one
level to the other. If the one or other key is kept pressed, the levels are rolled through.
When the 4 key is pressed in the "Amplitude" root display, programming mode is switched to without
entering an operator code. The amplitude can now be changed with the 0 and 1 keys.
If the 4 key is pressed in all other parameters, the entry of an operator code is expected.
-> .
After entering the code, this must be confirmed with the 5 key. If the code is correct, programming mode
is switched to. Depending on the access authorization (different codes are available for this; see the
"Operator codes" chapter), parameter items can be changed accordingly.
After completing the changes, these must be stored with the 5 key.
