• FLASHING FAULT (Amber LED)
The Detector is receiving a low signal (<100%) 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.
• ALTERNATING ALARM/FAULT (Flickering Red/Amber LED)
This state can sometimes occur. It means that the infrared power is stepping between optimum settings
(treat this state as OFF
).
