Description

PATENTKRAV 1. Et sikkerhedskredsløb til en røgrørsventilator, som er drevet af en lysnetforsynet asynkronmotor med hjælpevikling (L2) og kondensator (C), kendetegnet ved, at hastigheden kortvarigt øges umiddelbart inden der foretages en kortvarig aibrydelse (SC2) af forbindelsen mellem lysnettet (L) og kondensatoren (C), hvorunder et målesignal (E) udtages over hjælpevild ingen (L2), hvilket målesignal ved underskridelse af en forudbestemt værdi medfører udløsning af en alarm (A). 2. Et sikkerhedskredsløb ifølge krav 1 i forbindelse med en elektronisk hastighedsstyring af motoren, kendetegnet ved, at hastighedsstyringen (R, P, SCI) kortvarigt sættes til maximum umiddelbart inden den kortvarige afbrydelse (SC2) for opnåelse af målesignalet (E). 3. Et sikkerhedskredsløb ifølge krav 1, kendetegnet ved, at ved alarm sammenholdes oplysning om netspændingens tilstedeværelse med oplysning om strømgennemgang i motorkxedsløbet til at fastslå, om blokeret motoraksel foreligger.
