9. NOW place or uncover the reflector on the blank
wall directly opposite the beam head with a clear path though
obstructions such as girders etc.
It is important that there is a clear line of vision between the reflector and any
obstruction -the beam head must see at least 200mm of clear wall around the reflec-
tor to enable successful auto alignment.
Once the reflector is in place the AQ value should jump up
meaning that the head is now seeing the
reflector.
If you have received a AQ reading of over 40% go to Auto
Alignment point 10.
you need a reading of at least 40% to proceed to Auto align-
ment. If you do not receive an AQ signal of 40% it means the
beam head is not seeing the reflector. You will need to move
the beam head until you receive an AQ reading of above 40%
ideally over 100%
If you are presented with the screen below (AQ-air quality could be any number up to 40%)
Now look at the position of the reflector in relation to the beam head. You will need to
angle the beam toward the reflector by moving the head about its X or Y axis
using the internal motors
In the example on the next page you will notice that the reflector is below the line of
fire of the beam. So in this case you would need to lower the angle of the beam (-Y)
until you receive a AQ
(Air Quality) reading above 40% sensitivity. (40 steps of the motor =
1degree of movement)
The minimum response you need to see is 40%
(below this figure the beam will not self align in the
next procedure) the higher the number the better - this
can be over 100%
clear vision around
the reflector
