boat rudder angle indicator
The boat rudder angle indicator system is a set of device used to display the rudder angle information of the ship accurately and in real time in the bridge, cockpit and other places where the rudder angle information needs to be displayed. The whole device shall complete the functions of rudder angle acquisition, digital processing, digital transmission, display (digital and analog light band display), control (such as the brightness of the display), etc.
1. The cab and its four rudder angle meters are equipped with dimming function, of which the two wing rudder angle meters are equipped with dimmers, and the dimming potentiometers of the two rudder angle meters in the cab are connected according to the partial voltage connection method.
2. Before power on commissioning, remove the wiring terminals of all rudder angle meters, then power on and measure to confirm the DC24V power line and rudder angle signal line, connect the dv24v power line, and keep the rudder angle signal line suspended temporarily.
3. Check 6 rudder angle meters with signal transmitter.
4. The rudder angle transmitter and signal amplifier have high precision and few faults, so the system joint commissioning can be carried out directly. Power on the whole system, put the rudder angle of the steering gear at the zero position, open the top cover of the rudder angle transmitter, loosen the three screws fixing the rotating shaft (do not need to be removed), and adjust the rotating shaft to the indication of the rudder angle meter at 0 °.
5. Turn the rudder to port 35 °, and observe that the six rudder angle meters should indicate 35 ° on port. If there are rudder angle meters indicating 35 ° on starboard, reverse the signal lines of these rudder angle meters to make them indicate 35 ° on port.
6. Turn the rudder to 35 ° port and 35 ° starboard, and observe the indications of the six rudder angle meters. If the average degree is larger than A, turn the rudder angle to zero position, adjust the rudder angle range fine tuning knob, adjust the rudder angle table at the port 9A/7, then adjust and adjust the rudder angle transmitter zero adjustment knob, so that the rudder angle indicator is zero. If the average degree is smaller than A, then the rudder angle is zero, adjust the rudder angle range fine adjustment knob, adjust the rudder angle table at the starboard 9A/7, then adjust and adjust the rudder angle transmitter zero adjustment knob, so that the rudder angle indicator is zero. Then turn the rudder again to 35 ° on port and 35 ° on starboard, and observe the indication of the six rudder angle meters. If there is a large deviation, repeat the above steps for adjustment.
