Abstract

1395092 Automatic sequence control TECHNICAL ARCO ESTABLISHMENT 25 Jan 1973 [28 Jan 1972] 3721/73 Heading G3 A plurality of electromagnetic relays having change-over contacts are actuated according to a predetermined sequence by a programme-switch through three conductors two of which are signal conductors alternatively transmitting pulses. As shown, a pulse through a conductor fd energizes a relay I through contacts Cl, which change-over to allow a pulse through a conductor fp to operate a relay II. The sequence continues by alternate connection of lines fd,fp until relays III-VI are actuated. The resistance R1 is provided to light an indicator in a programme-switch, not shown. The programme-switch comprises a transistor oscillator and a rotary relay mounted on a printed circuit board in association with a control panel carrying manual/automatic sequence control switches and indicating lights.
