In manual mode the desired position can be set by using the switches on the EKU-N. The motor position feedback is defined by means of a potentiometer that has to be fitted into the gearbox of the motor.

It is possible to set an emergency position in the EKU-N, the air inlets will be controlled to this position when the control signals fails.
