Internal GPS Synchronization
It is necessary to take into account the power consumption of the GPS unit in any power
calculations. The GPS sync unit only operates when the beacon is programmed to run (night or
day/night). The clock is updated from the GPS satellites every 20 minutes and the typical
acquisition time is around 2 minutes. The GPS current is detailed in Appendix B
If GPS synchronisation is required for a number of beacons that are in close proximity it is possible
to fit only one GPS unit and to connect the other beacons using hardwire synchronising.
8.3
Alarm Monitor wire
The alarm monitor wire is used to provide an indication when the VLB-67 is not working. This
alarm monitors the current of the Beacon and the supply voltage.
Output is connected to ground when
x
No voltage or low voltage is present.
x
No LED current or low current is detected when the VLB-67 beacon should be on.
x
Alarm is being tested using Operation mode 1-5-007 (Section 4 Clause 5.6)
The monitor output operates as an electronic relay with one side connected to ground (battery
negative). A 0 to 20VDC can be applied to the alarm/monitor output. The maximum current the
monitor output can handle is 400mA DC. Do not connect to battery positive. For additional details
refer to the specification section.
8.4
Data Port
The RS232/RS485 data
port can operate continuously or “on demand. The “on demand” mode
uses less power than the continuous mode. When the data port is used the additional power must
be taken into account when calculating the overall power requirement if the VLB-67.
The data port shares common circuitry with the IRDA port that is used for programming the VLB-67
from a computer. Only one data port can be used by the VLB-67 at any time. Operation of the
data ports is selectable using the Vega Remote TVIR programmer.
Details of the data port protocol and the beacon parameters available are contained in Appendix G
SECTION 3 MAINTENANCE
1.0
Maintenance Cleaning
Vega LED beacons require little to no maintenance.
Solar panels on the VLB-67 SS and LS models should be inspected and cleaned occasionally to
ensure maximum solar energy capture. Use warm soapy water to wash the outside of the beacon
and rinse off with clean water. Do not use any solvent-based cleaner.
2.0
Inspection Check
Periodically check that the beacon remains firmly secured and level, and the mounting fasteners
are still in good condition. Investigate any corrosion and take appropriate preventive action.
The Beacon can be tested by programming for the “test “mode or if daytime covering the lens
briefly to simulate night time operation. When the light is flashing check it is displaying the correct
flash character.
Remember to remove any lens cover before leaving the site.
