The WFU-500 Follow-up Rudder Control System is employed to transmit rudder commands from the bridge to the power unit of the steering gear. It comprises components such as a follow-up rudder wheel, rudder angle feedback device, rudder angle indicator, and follow-up control unit. During operation, rudder commands are issued via the follow-up rudder wheel. The follow-up control unit compares the actual rudder angle with the command, outputs instructions to control left and right solenoid valves, continuously adjusts the steering gear angle, thereby enabling the steering gear to follow the rudder...

As illustrated, the traditional simple steering method employs a handle or handwheel switch to control the on/off state of an electromagnetic valve. When steering, continuous pressure must be maintained; if released, the electromagnetic valve immediately de-energizes. This not only leads to easy damage of the handle but also causes fatigue for the steering operator. The modified follow-up steering system is as shown in the following figure: Schematic Diagram of Follow-up Steering Principle for Old Ship Reconstruction Left and right electromagnets Switch control signal' Rudder Electrovalve Pattern...

Place the handwheel vertically into the opening in the installation plate as shown in the lower-right corner of Figure 4.1, align the screws with hole B, and if encountering protruding parts, rotate or tilt the handwheel to insert it. Installation Step Diagram As shown in Figure 4.3, install the A clip of the follow-up rudder unit into the B slot, ensuring it is secure and reliable.

As shown in Figure 4.4, install instrument A onto the mounting surface of B to ensure secure attachment. he rudder angle feedback device must be installed flexibly according to the type of rudder motor, secured with M8 triple combination screws and nuts. A threaded rod connects the lever arm and the rudder handle, forming a parallelogram linkage structure to ensure that the rotation angle of the rudder handle is equal to the rotation angle of the feedback device's lever arm. 1. Installation of the swing cylinder type rudder motor rudder angle feedback device: The swing cylinder type rudder motor...

1. The system is powered by 24VDC ± 2V, and the solenoid valve control is active output; 2. In the dual rudder follow-up control system, the follow-up steering unit corresponds one-to-one with the rudder wheel potentiometer and cannot be interchanged; 3. Upon first use, check the left and right rudder drive signal outputs. If the signals are reversed, it may cause the rudder to turn fully in the opposite direction; 4. To prevent excessive load on the rudder motor solenoid valve, follow-up steering units typically come equipped with relays at the factory. The drive signal is output through the...

value normally; 2. If the digital tube on the drive circuit board displays ER1, it indicates that there is no rudder angle signal; 3. If the digital tube on the drive circuit board displays ER2, it indicates that the rudder angle value is out of the normal range; 4. If the digital tube on the drive circuit board displays ER3, it indicates that there is no signal from the rudder wheel potentiometer.
