Schaltungsanordnung zur Sicherung elektronischer Bauteile
The circuit protects modules using electrical protection lines (M1,M2). The lines are statically monitored for detecting line breakage and short-circuits and dynamically monitored for detecting partial short-circuits via a separate monitoring circuit. The static and dynamic monitoring circuits (CB,V...

Summary: | The circuit protects modules using electrical protection lines (M1,M2). The lines are statically monitored for detecting line breakage and short-circuits and dynamically monitored for detecting partial short-circuits via a separate monitoring circuit. The static and dynamic monitoring circuits (CB,V6,V7,V8 ; S1,S2,V4,V5,SHC) are operated in alternation. Switching between the two protection circuits is controlled by a pulse control (OSZ). The dynamic monitoring circuit is switched to only for the duration of the measurement, while the static circuit operates during the remaining time period. A detected line breakage or short-circuit is used to activate an alarm (AL1) and/or initiate a protection function. |
