FLASHING RED
The Detector is receiving too much signal and is attempting to reduce the infrared power output to compensate
.
Wait
at this point until the indicator lamp is
OFF
, this may take up to 20 seconds depending on the distance
between Detector and Prism(s), the shorter the distance the longer the time.
•
FLASHING AMBER
The Detector is receiving a weak signal and is attempting to increase the infrared power output.
•
OFF
The Detector has optimised the infrared power and receiver gain for the current orientation of the Detector
and Prism(s).
This does not mean that the Detector to Prism(s) alignment is at its optimum
, i.e. if the
power is too high, a misaligned Detector may be receiving a fringe reflection from another object.
•
FLICKERING RED/AMBER
This state can occur sometimes. It means that the infrared power is stepping through the optimum setting
for the current orientation of the Detector and Prism(s).

flashing?
For optimum alignment,
deflection of the beam in all four
planes should cause the Amber
LED to flash first
Stop turning the
thumbwheel and
wait for the Red
LED to stop
flashing.
Stop turning the
thumbwheel.
