3. Maintenance
3.1. Scheduled Maintenance
The FlightTransport systems are relatively maintenance free. There
are no annual adjustments or maintenance routines required.
All system performance can be monitored with the FMG network
management systems. The most important parameter is always
Received Power. If the Received Power level has dropped, the system
should be manually checked to determine the cause.
3.2. Annual Maintenance
The front window of the link heads should be cleaned with a soft moist
cloth once a year using water or a commercial glass cleaning solution.
In a dusty, smoky or polluted environment the window may need to be
cleaned more often. A continuous drop in Received Power levels
(averaged over a period of 48 hours) will indicate the need to clean
the glass or re-align the system.
During this annual maintenance, check the link heads for good
alignment. The mount may have settled. Assuming that the weather
is clear, the Receive Level Bars should display the same level which
you noted during the installation. Check for obstructions in the
transmission path such as growing trees, mechanical equipment or
new construction. Check all electrical connectors for corrosion,
moisture or other damage. Check all optical cables for damage or
changed routing.
REMEMBER - On single beam systems you may be interrupting the
beam for a fraction of a second as you wipe the glass clean. If you are
cleaning a multiple beam system, this is not a problem -- all four
beams are transmitting the same information and the momentary
interruption of up to three beams will have no affect on your users.
WARNING - Do not stare (look) directly into the front of the link head
from close range. Do not attempt to open the housing, there are no
user-serviceable parts inside.
The power level should be logged at initial installation. If the power
level begins to drop, there is a chance that the front window has
become dirty. It is also possible that something in the Line Of Sight
has changed (leaves, new construction, heating or cooling equipment,
smokestack) that has lowered the power levels in some way and
should be corrected.
