For modulating control actuators, note the control characteristic for the selected switch-on point of the setpoint.

Actuators
GMA161.1, 166.1
(DC 0...10 V)

The diagram shows the setting characteristics by including the neutral zone. The values for the neutral zone listed in the diagram apply to DC 0...10 V (without characteristic function).

The diagram shows the relationship between the differential voltage E = Y – U (difference between setpoint Y and actual value U) and the rotary direction, including hysteresis and neutral zone.

Actuators
GMA163.1, 164.1
(DC 0...35 V)

For DC 0...35 V (with characteristic function) the following values apply:

Neutral zone NZ = 2 % of span ΔU.

Hysteresis H = 0.7 % of span ΔU.
