The modes can be changed on the fly for fail-safe operation
, preventing the system from closing or resetting if errors are present.
Both capacitors offer a fused, segmented metalization pattern, to provide significant circuit protection and the UL 810 approval assures fail-safe operation
under fault conditions.
In terms of security, Lawo's STAR technology provides redundancy and fail-safe operation
The base structure module consists of a base frame, ball bearing brackets, a constant-force spring to apply a restoration force on the mechanical driving part during fail-safe operation
, and limit switches to monitor and judge the status of each mission mode.
The third pillar to tackle was fail-safe operation
. This has seen ThyssenKrupp develop a very high redundancy and diverse system to check positions, speed, direction and distances between cabs, as well as safe communication between the cabs.
"It was a fail-safe operation
," said Jeff Ziller, the department's district biologist.
In the field incident in which the pedal examined by NASA was involved and in the only other three incidents that appear to be of that nature found in the VOQs, the resistive short triggered a DTC and fail-safe operation
