Meaning and possible remedial action.
If a fault persists then seek advice. Any remedial action requiring wiring
or replacement of parts, this work must be done by a trained engineer.
Check the line of sight between the beam transmitter
and the reflector for a blockage in the beam path.
Action: Find and remove the obstacle causing the
blockage.
Beam incorrectly positioned was detected.
Action: Check and take corrective action to ensure
beam sensors are correctly positioned.
The beam detector is currently in initialization
mode (booting up). This mode should clear after the
initialization period has ended.
Action: If this message persists then the beam detector
is faulty and must be replaced.
Beam local obscuration test has failed.
Action: Clean the transmitter and reflector and repeat
the test. It is possible there is incorrectly aligned beam
(run through beam alignment procedure again and
repeat test). The beam detector remains in fault until
reset or timeout.
