VSL-73 ALL AROUND LED SECTOR LIGHT The VSL-73 Sector Light forms part of the Vega LED marine beacon family and is designed for omni-directional applications where precision sectoring is required. The VSL-73 provides a LED alternative for shadow casting sector lights using incandescent lamps. The VSL-73 can be used for sector light applications ranging from 4NM to 10NM with a normal visibility of 12NM (0.74T). Each VSL-73 is customized for the particular application taking into account the required range, colours, and sector angles. Mechanically the VSL-73 is available in any combination of subunit (half unit) and full unit up to a maximum of a 3 unit high version. A full unit consists of 6-lens layers that can be the same or made up from different colours. A full unit in one colour will typically have a range of 10NM at 0.74T. The sector angles are created using a mask fi tted inside the outer acrylic wall. This provides a beacon that is suitable for outside use (IP67) and is easy to install and align. The customer is provided a base mounting drawing detailing the mounting relative to true north. A rotational adjustment of ±5° is provided on the VSL-73 for on site sector alignment. To maximize energy effi ciency only the LEDs required for the sectoring are used. This reduces the cost for any solar powered applications. Standard colours are white, red, and green. For other colours please refer to Vega. All colours meet IALA chromaticity requirements. PERFORMANCE AT A GLANCE • Range of between 4 and 12NM at a transmissivity of 0.74T • Vertical divergence of 5° to the 50% intensity level • Sector angles from 2 to 360 degrees • Angle of uncertainty better than 0.5° colour to colour and better than 1° at sector edge REPLACING A SHADOW CASTING SECTOR LIGHT A typical shadow casting sector light has a larger range for white than for the green or red sectors. For example 5NM white and 3NM red, this is due to the lower transmissivity of the colour fi lters. When changing to a VSL-73 LED Sector Light each colour is provided by separate LEDs, this provides the option to 1. Leave the range of the colours the same 2. Decrease the white range to the same as the colours 3. Increase the colour range to the same as the white sector Most shadows casting sector lights are sized for the range of the colour sector. Reducing the white range to be the same as the coloured sectors will provide the most cost effective solution when using the VSL-73 LED sector light. INSTALLING THE VSL-73 LED SECTOR LIGHT Each VSL-73 is supplied with a base mounting drawing indicating the position of true north. The mounting for the sector light needs to be prepared to match the correct orientation. Once mounted the VSL-73 has an adjustment of ±5° to allow for fi nal alignment. OPERATION OF THE VSL-73 LED SECTOR LIGHT A VSL-73 is programmed as a single unit regardless of how many sub and full units are used in the sector light. The operation of each sector is monitored and various options are provided on how the light should behave should any problem be detected with a sector. One option, for example, is to shut down all sectors should any sector of the light fail. The VSL-73 is supplied with a RS232 or 422, and IRDA data port, an alarm/monitor wire, and hardwired synchronising. Additional Options • GPS Synchronization using the VSU- 29 GPS Sync Unit EASY PROGRAMMING There are two methods of programming the VSL-73 LED Sector Light: 1. Using the Vega TVIR programmer (Remote-02). This allows the beacon to be programmed one feature at a time. The VSL-73 LED Sector Light confirms the settings by flashing the programming code back to the user. 2. Using a computer and the IRDA interface (Prog-02). This allows all the VSL-73 LED Sector Light settings to be displayed on a screen and downloaded or retrieved in a single action. 3. The VSL-73 LED Sector Light supports the standard features found on Vega marine LED beacons. • Automatic Schmidt-Clausen intensity correction for short flashes • Multiple effective intensity settings • Day/night transition level settings • Programmable flash characters • One programmable custom character • Synchronisation control including master/slave options and sync delay • Programmable sleep and test modes • Programmable low battery voltage cut out • Program control of the IRDA and RS-232 data port. • Individual control of each sector colour • Program control on how VSL-73 responds to sector failure • Optional security code • Read supply voltage • Serial number, LED type etc, are stored in sector light MONITORING Monitoring of the VSL-73 LED Sector Light can be provided in a number of ways: 1. Using the Vega Mini VegaWeb internet monitoring unit. 2. Utilising the factory data port option. This can be RS-232 or RS-485. 3. Using the alarm/monitor connection option.
