repeater is made clear by means of thecircuit diagram. The operator on line L has opened his key prepar-atory to sending a message, consequently at this instant there is nocurrent on the line and the contact RC of relay R is open. Whensignals arrive, relay R responds and operates magnet TM,… … Fig. 17. Wiring Diagram for Weiny-Phillips Repeater Circuit tact C must therefore remain closed, otherwise relay R would beinoperative, but it is closed only when magnet TM is energized byrelay R\ The diagram shows this condition, but it also showsthat the circuit of relay magnet RM is momentarily…
