Fig 5.7: Functions of the control unit front side
1 Display
Information of Voltage or Current output. The display is only for monitoring
purposes, but doesn’t provide the accuracy of an measuring device.
2 Power on
The LED signalizes the ON / OFF status of the device
3 RF Level
The LED shows a sufficient signal level for data transmission from rotor to
stator.
4 Gain switch (see also (8)
Switch for activating the adjustment functions of (8). Therefore the switch must
be set to “variable”.
IMPORTANT: Characteristic values of calibrated transducers their validity loose
in mode “variable”. In mode “fixed” the potentiometer (8) is deactivated.
5 Filter switch
Switch for selecting the signal bandwidth.
6 Cal – function
Switch for activating the defined bridge detuning “Shunt Cal”. The LED lights for
approx. 5sec after activation of the switch. After 5sec the measuring system
returns self-dependent to operational mode.
7 Offset
Potentiometer to adjust the Offset between ±1V. This function only effects the
voltage output, not the frequency output.
8 Gain
Potentiometer 6b to adjust the measurement signal output (nominal ±10V with
factor 0,2…2,0). Switch (4) for activating the adjustment function of (8).
Therefore the switch must be in mode “variable”.
9 Analog output
Analog output signal (±10V)
10 Frequency output
Frequency output (10kHz ±5kHz, 5V)
