Ship Navigation Light Indicator Panels

Ship Navigation Light Indicator Panel

 

Ship Navigation Light Indicator Panels Not compliant with IMO: MSC253

 

Specialized circuitry prevents bulb burnout and extends the service life.

 

 

 

Ship Navigation Light/Signal Control Panels Compliant with IMO: MSC253

 

 

 

 

Ship Navigation Light Indication


The DC power source is a three-line system such that if one line is lost, the DC power indicator remains lit up and the red lamp of the power loss indicator lights up.
 
Anchor/Ship Navigation Light Switch

A switch is equipped to change between navigation and anchorage lights.

 

 

Navigation Mode


- When a ship navigation light burns out, the panel automatically switches to the spare light and flashes to indicate that the light has burnt out.
- The switch for changing between anchor and navigation is a rotary type.
- The use conditions are recorded, and operating the anchor/navigation switch enable for illumination/illumination control of all signal lights.
 
Anchor Mode

- If the anchor light bulb burns out, the switch LED flashes and the buzzer sounds.
- If a two-light system is used, the switch is an on/off power switch, and up/down and light bulb burnout alarms are displayed on the signal light operating panel.

 

 

Light Bulb Burnout Check


- You can check for light bulb burnout before operation using the Function Test switch.
- The buzzer makes a beeping sound twice if the light bulbs are normal. If a light bulb is burnt out, the corresponding LED flashes and the buzzer sounds to indicate that you must replace the bulb.
 
Transmission Error

Transmission lines are equipped between the signal light operating panel and the ship navigation light indicator panel. If an error occurs, (FAIL1) flashes and the buzzer sounds to alert the user of the error.

 

 

Signal Light


- Manoeuvring lights are linked with the steam whistle, and linked externally through operations from the steam whistle operating board such that the switch indicator LED is repeatedly lit up/turned off.
- The operating switch cannot perform on/off operation. When a signal is input from the steam whistle, the switch LED flashes if the light bulb is burnt out, and the buzzer sounds. Control is started by pressing the switch one time, and operation by pressing two times.
 
All-Round Lights

The all-round light switches are equipped with various functions such that if the bulb of a single light of equipment on the starboard, port or both sides is burnt out, check external light bulbs after the buzzer is stopped.

 

 

Flashing Lights


- An alarm is output for a burned-out bulb of a flashing light.
The LED of the corresponding switch on the operating panel lights up and the external signal light starts to flash.
- If the light bulb is burnt out, this LED flashes and the buzzer sounds.
Turn off the power to stop the buzzer and replace the light bulb.
 
Current Detection Devices

- The circuit board for detecting electrical current is equipped with a DIP switch for setting the output (can be set from 20 W to 300 W in 20-W increments) and signal light names, and a DIP switch for setting either one or two-light format.

 

 

NMEA Signal


- As standard equipment, this system has serial communication for saving a record of operation to a VDR or similar device. Transmission is performed using RS422 with software complying with IEC61162-1 (5,2,1,3).
- If there is operation or a burned-out light bulb of the ship navigation light indicator panel/signal light operating panel, a signal is automatically sent from this communication line to an external recording device.
 
External Buzzer Stopping Circuit

- MSC253(83) requires that external checking be possible. A stopping circuit for external buzzers other than RS485 transmission report is included as standard equipment.
- If a buzzer is stopped by the circuit, always perform a final check using the ship navigation light indicator panel/signal light operating panel.
- If the buzzer is stopped and then left alone, it will sound again in another 30 seconds.

 

 

Dimmer Switch


- MSC253(83) requires that external checking be possible. A stopping circuit for external buzzers other than RS485 transmission report is included as standard equipment.
- If a buzzer is stopped by the circuit, always perform a final check using the ship navigation light indicator panel/signal light operating panel.
- If the buzzer is stopped and then left alone, it will sound again in another 30 seconds.
