Structure, Function and Working Principle of Main Parts or Functional Units

The navigation and signal light controller is to control work state of navigation and signal lights. There is simulated ship form, and the navigation and signal lights are laid in this form according to the positions of real ships. It has the functions of controlling open, close, monitor, failure alarm, erasure, test and power-loss alarm of navigation and signal lights

This controller has the functions of two power source indications and two power-loss alarms

The navigation signal light controller adopts the thin film buttons and division structured design, and controls the work and monitor of the above-mentioned light by intelligent chip

This light has the main and back-up functions. When the main light fails, it can automatically transfer to the other line

It has standard serial 485 interface for marine celestial navigation and communication system, and this interface conforms to relevant requirements of GB IEC61162

The portside and starboard lights provide two contact signals to light control respectively, which supply the “NAVIGATION” signal for light control

AC220V and DC24V distribution boxes are set in the control console, which supply reliable power to each electric equipment

In the control console, there are also control switch of external lighting, power indicator as well as light control switch, power indicator and firefighting pump remote control unit

Connect all the support equipment of the control console in accordance with the cable connection diagram, and check if the power supply is normal. After confirmation, turn on the power switch and enter the use state

Control the open and close of external load navigation signal light by the buttons on the panel

Press the “LIGHT DEBUGGING” button on the control panel, and check if the panel simulating indicator light and buzzer alarm sound are normal

When the panel light is debugged, the alarm function works normally

After pressing the “ALARM CONFIRMATION” button, all alarm loops will automatically turn off

Press the “ERASURE” button, only the buzzer alarm sound and relay output will be erased, and the alarm state of the simulating light is not influenced

After alarm confirmation and erasure, repress the failure navigation signal light and then external load light turns on

After pressing the “DIMMING” button on the panel, this controller will start its four-class function, and the system keeps the dimming class automatically, which will not be lost at power failure

This controller can observe current states of main and back-up power supplies on the simulating panel, and has the alarm function of main and back-up power failure

The distribution box is laid in the front door the control console. Each circuit is controlled by air breaker and there are labels to mark names of electric equipment. When it is necessary to supply power, turn the air breaker to be “ON”

When there is any short circuit in the equipment, air breaker turns off automatically and plays a role in protection
