Technical error
A technical defect (casually "technical breakdown") is a malfunction of machines or systems . It always has a cause and leads to an undesired change or stop of an originally planned process.
causes
The malfunctions can be very different depending on the complexity and processing of the process. Errors are conceivable that can be attributed to the following factors, for example:
- Material fatigue ,
- Program error ( fed in data , program run error),
- Operating errors through human error (reckless or negligent) or maliciously through sabotage ,
- incorrect assembly or installation,
- Construction errors ,
- lack of compatibility with a dependency on other components or parameters,
- lack of electrical contact ,
- insufficient or missing energy supply ,
- Exceeding / falling below the ambient or component temperature,
- Errors in data processing ; For example, data transmission , information loss , calculation errors .
The errors can occur individually or simultaneously as well as in rapid succession.
consequences
The consequences are very diverse and of varying degrees. A frequent consequence is damage that may be associated with accidents . One consequence can also trigger a chain reaction, for example an uncontrollable core meltdown in nuclear reactors.
Precautions
Program routines can control possible risks with predetermined borderline parameters. Either the source of the error is eliminated or dependent processes are stopped (the latter also includes the emergency stop function , which, depending on the system, can also be initiated manually).
Machine operator : In addition to visual warnings such as warning signs or warning signals and acoustic warning signals, modern systems also have automatic shutdown, for example the dead man's device .
