VLB-44E LED MARINE BEACON – EXTENDED FEATURE MODEL
The extended feature model of the
VLB-44 LED marine beacon is intended
for application where an increased level
of control and monitoring is required
compared to the standard VLB-44
beacon. In particular these additional
features allow the beacon to be used
in harbour traffic light applications as
detailed in the IALA recommendation
E-111 1998.
To allow flexibility to resolve the day
visibility for traffic light applications the
VLB-44E can be configured from 1-8
tiers with any combination of vertical
divergence lenses. The VLB-44E lenses
comprise vertical divergences of 2.5, 5,
and 10 degrees. There is also a wideangle asymmetrical lens that points
downwards below the horizontal to
provide close in visibility of the light. The
asymmetric lens has its peak intensity
on an angle of 8 degrees below the
horizontal and has a divergence of ±5
degrees either side of the peak.
The ability to select the lens divergence
for each tier of the beacon allows the
performance of the light to be adjusted
depending on the designed mounting
height to ensure it remains visible as a
vessel approaches. A 2.5 degree lens
or lenses is used for the long range
intensity requirement and the wider
lenses including the asymmetrical lens
are used to provide intensity at the larger
angles when the vessel is closer and
possibly below the mounting height of
the light. Vega can assist with the lens
selection if required. The information
needed is the mounting height, required
day range, colour, flash character, and
the minimum and maximum viewing
height for vessels.

The total intensity capability of a light can
be determined by adding up the intensity
of the individual lens used in the beacon.
EXTENDED FEATURES
There are two operating modes depending
how the VLB-44E beacon is programmed
• Normal Mode
– Day/Night transition controlled by
light sensor in beacon.
– On/Off input can turn light on if it is off.
• Traffic Light Mode allows manual
control of the beacon
– Internal light sensor in beacon is inactive
– Beacon operation On/Off input controls
– Day/Night input controls high/low intensity
– Character 1 / Character 2 controls
flash character normally Flash/Fixed
for traffic light applications.
Additional features provided include:
• Alarm/monitor output (Beacon Healthy)
• Beacon on output
• RS232/485 data port
All VLB-44E Beacons are tested in the
Vega zero range light tunnel prior to
shipment to ensure the light output meets
the required specification.
EASY PROGRAMMING
Programming is done using the Vega TVIR
programmer.
The VLB-44E LED marine beacon 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 for
normal mode
• Programmable flash characters
• Programmable custom 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 RS-232 data port
• Optional securiy code.

MONITORING
Monitoring of the VLB-44E LED beacon
can be provided in a number of ways:
1. Using the Vega Mini VegaWeb
internet monitoring unit.
2. Utilising the data port. This can be
RS-232 or RS-485.
3. Using the alarm/monitor output.
