1.1.4.1.1 Adjusting Potentiometers Adjusting the Potentiometers The potentiometers are aligned in the factory. The middle position of the potentiometers corresponds with the mark on top of the axle and the red dot on top of the Rudder Feedback Unit MD. When further adjustment is to be made, this has to be done in the equipment connected to the Rudder Feedback Unit MD. - Page 17 Figure 13: Rudder Feedback Unit HD Electric Connections When the connections have been made, close the front hatch of the Rudder Feedback Unit HD. When replacing the screws, first apply the middle top and the middle bottom screw of the hatch and torque to 6,5 Nm. After this, all other screws can be replaced and torqued to 6,5 Nm.
