1. Application and design
The NLS 3000 navigation light control panel serves for switching and monitoring up to 48 lights
onboard ships. These can be switched on or off individually. Two power supplies can provide the
power for the lights (main and backup). Selection between these two supplies can take place either
manually or automatically in the event of failure of the power supply currently in use.
The NLS 3000 navigation light control panel is in a modular design. The light modules (light switching
and monitoring) are installed in a control cabinet together with the main module (power and master
module monitoring). The control panels (conventional with buttons and LEDs or graphic with
touchscreen) can be arranged projecting.
The individual modules are interconnected via a bus cable that supplies the modules with operating
voltage.
The system is organised according to the master-slave principle. This means that a master module
collects the information from the slave modules, evaluates and manages the information and initiates
actions at the slave modules.
For this purpose, the master (main module) must know which lights must be evaluated with which
values and what actions need to be initiated in the event of failure. The system topology must also be
known. This is achieved by the configuration of the main module and is permanently stored in the
internal EEPROM. This configuration is simply written into the main module by text file transfer
(terminal or SD card via data module). The text file containing configuration data and menu texts is
arranged so that it can effectively be generated from Microsoft Excel tables.
