O que significam xsh, xgl e xgsl? E como essas duas válvulas funcionam?
Reply #22018-04-02
São duas válvulas de corte, que funcionam apenas como interruptores, e possuem intertravamento. XGL é o detector de interruptor de posição (exibido no DCS); XHS são os sinais manuais de ligar/desligar fornecidos pelo DCS; o sinal de posição XGSL, por sua vez, participa do sistema de intertravamento.
