OSS Pre-Start Inspection
(See Figure 3-10.)
From ground controls, raise platform approximately 5'-6'. The RED
LED on the electronic module will be illuminated when power is
applied. If an obstruction, such as a pad of paper is placed under
any of the transducer sensor arrays, the RED LED will flash and
remain flashing while the obstruction is present and stop flashing
3 seconds after the obstruction is removed. Check the operation
of each transducer sensor array by placing an object individually
under each sensor array (within approximately 6"-12") and check-
ing if the RED LED starts to "flash", and stops flashing 3 seconds
after the obstruction is removed. Also, inspect the transducer
arrays and electronic module for physical damage, loose wires,
loose mounting hardware, etc.
