Lessons Learned - OPF Payload Bay Bucket Limit Switches.
Year: 1992
Abstract: Description of Driving Event:
Failure of one or more of these component switches 1S8, 2S8, 3S8, or 4S8 in the closed position would cause a short circuit of relay K11, thus not allowing any of the 16 bucket proximity limit switches on both buckets to stop travel. This can result in damage to flight hardware (payload and/or vehicle) due to buckets hitting hardware.
