Fail-safe operation: Distributed system will keep on working even with some of its components are out of order.
The system is strictly mechanical--no hydraulics, pneumatics or electricity--for fail-safe operation, even on wet or contaminated guides.
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.
With the proper pilot assembly, the reservoir is constantly pressurized and able to perform the fail-safe operation during a power failure or catastrophic air failure.
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.
The bendable probe offers interference-free, fail-safe operation and "Quick-Set" calibration.
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."
This film technology combines high rms current capability with high reliability and fail-safe operation, especially in harsh environments that experience a wide range of temperature, humidity and transients (from lightning strike to grid).
