3. Follow-up (Rudder Feedback) Unit 4. Solenoid Interface Valve The Model 7173-K System is used to set the position (or the angle) to which the Rudder goes. The Amplifier Unit compares the respective command and feedback signals from the Controller and Follow-Up Unit.
MOUNTING THE MODEL 7174 RUDDER FEEDBACK UNIT The Model 7174 or 7168 Follow-Up (Rudder Feedback Unit) must be mounted near the steering gear as shown in the diagram below. The output signals will then be calibrated with the tiller in place.
The input power to the Model 7173-K Amplifier Unit is 11 VDC to 28 VDC. The power cable (2-conductor, #14-gauge) should be run from the switchboard through a customer-supplied on/off switch via a circuit breaker or fuse (8 amp).
Also, rudder limit adjustment can be achieved by adjusting rudder limit trim pots on 7173-K board or by adjusting the stroke on the feedback unit. NOTE: You must not allow the cylinder to continually push against the mechanical stops (hardover position).
