6.4.4 Adjustment and configuration
For impedance input, the switching polarity can be configured with the three pin
terminal strip below input. The switching point can be adjusted with the potentiometer
"SETP ANA". The hysteresis can be adjusted at the potentiometer "HYS ANA" i.e. the
difference between switching ON and switching OFF point.
The input amplifier is to be programmed for different modes of operation with the
jumper connection "ANA MODE":
The analog input can be configured over a wide range through the jumper
connections:
