<p>The switching system (10) is designed to prevent response to fault conditions, and serves to monitor the quasi-simultaneous operation of two switches (TA,TB). The switches are connected to relays (18,19) supplied from separate units (UE1,UE2) and also connected to a charge path (12) with a capacitor (11). The path has a number of contacts (A1,B1,C1,D1). The output actions (22,24) are only triggered when both inputs are correct.</p> |
