The incremental setpoint generator is used to preset an analog value (0 / 4–20 mA, 0–10 V) with the aid of external control signals. The output range from 0–100% is divided into 256 steps. The output change by one step is carried out by an input pulse of at least 64 ms in length. With a continuous signal, there is an automatic change approx. every 282 ms by one step (ramp function). An infinite ramp function when the signal direction is reversed at the range limits can be configured. Potential-free contacts as well as active voltages of 5–30 V DC can be used as input pulse sources. The signal setting can also be made with the two device buttons. Pressing both buttons at the same time for approx. 2 seconds saves the instantaneous value as the start value after a supply voltage failure. The storage process is acknowledged by blanking the operating voltage LED. There is a red LED for each signal direction input, which indicates the active input status. During the ramp function, the respective LED flashes according to the direction of change. The output signal is galvanically separated from the active inputs and also from the supply voltage.
The following can be configured using AD Studio software:
- Number of steps (2 ... 1000)
- Time interval per step (10 ... 2000 ms)
- Area limits
- Ramp function
- Signal start values



Presetting of analog values by means of external control signals (contact or DC voltage).
