Setup and Adjustments

Direction of Action

The M9220-GGx-3 Proportional Electric Spring Return
Actuators are factory set for Direct Acting (DA)
operation. In DA mode, applying an increasing input
signal to the control input drives the actuator away from
the spring return position. Reverse Acting (RA)
operation is also available. In RA mode, applying an
increasing input signal to the control input drives the
actuator toward the spring return position. Figure 12
and Figure 13 indicate how the drive direction for the
actuator depends on the spring return direction and the
position of the mode selection switch.
