Product description
4.2  Function
The sensor amplifier works as a base unit for a special 
series of capacitive sensors (half variants without their own 
switching power amplifiers, especially mini and high-
temperature sensors). The sensors detect objects or fill 
levels, for example, and forward the information to the 
amplifier. Operation in a control loop uses the entire 
working range of the sensors. Further signal processing 
takes place in a microprocessor.
The software periodically records the control voltage and 
uses it to generate a switching or analog signal, which is 
emitted at the output.
The following parameters can be adjusted:
–  Switching stage: PNP, NPN, push-pull, N.O., N.C.
–  Adjustment or automatic teach-in of the sensor sensiti-
vity to the switching distance application
–  Remotely triggered, situational teach-in of sensor 
sensitivity to application (via a fourth program line)
–  Different switching modes with one or two switchpoints
–  Switch on and off times
–  Dynamic operation
–  Detection of only moved objects
–  Permanent, slow background suppression
–  Analog function with analog output (4…20mA, 
0…10V)
The amplifier is operated via menu settings (buttons and 
display).
The output is protected against overcurrent and short 
circuits. The limit values for overcurrent (approx. 200mA) 
and for overheating are fixed settings. An overcurrent/short 
circuit error is indicated on the display with

NC LED (red) Does not light up if no operating 
voltage is applied or N.O. is 
configured.
Lights up when operating voltage 
is applied and N.C. is configured.
