4) Reverse action
Increases the manipulated variable (output frequency) if deviation X = (set point - process value) is
positive, and decreases the manipulated variable if deviation is negative.
Set point
5) Forward action
Increases the manipulated variable (output frequency) if deviation X = (set point - process value) is
negative, and decreases the manipulated variable if deviation is positive.

Sink logic
Pr. 128 = 20
Pr. 183 = 14
Pr. 192 = 16
Pr. 193 = 14
Pr. 194 = 15
Note: 1. The power supply must be selected in accordance with the power specifications of the detector
used.
2. The output signal terminals used depends on the Pr. 191 to Pr. 194 settings.
3. The input signal terminals used depends on the Pr. 180 to Pr. 186 settings.
