Technical failure

A technical defect ( casually " technical glitch ") is a malfunction of machines or systems. She always has a cause and leads to an undesired change or stop of an originally planned sequence.

Causes

The malfunction can be very different depending on the complexity and processing process. Are conceivable error, for example, are due to the following factors:

• Fatigue
• Error ( fed data, program execution error )
• Incorrect operation by human error ( recklessly or negligently ) or maliciously sabotage
• Incorrect assembly respectively Installation
• Lack of compatibility with a dependence on other components or parameters.
• Lack of electrical contact
• Insufficient or lack of energy
• Over or under the ambient temperature or component
• Error in data processing; such as data transmission, loss of information, calculation errors

The error can occur individually or simultaneously and in rapid succession in time.

Follow

The consequences are very diverse and of varying degrees. A common result is damage that are possibly affected by accidents. A sequence can also trigger a chain reaction, for example, an uncontrollable meltdown at nuclear reactors.

Arrangements

Routines, disqualify any risks at given marginal parameters. Either the fault is found or there are dependent processes stopped ( for the latter part of the emergency stop function, which can also be initiated manually depending on the system ).

Operator: In addition to optical warnings like warning signs or warning signals and acoustic warning signals are available in modern systems, the auto-off, such as the Deadman.
