Hi
in post-40 is the question "in what applications does a AC-Relay not use the full coil voltage supplied by the transformer ?". Some text to this are in post-65 through -69, -71. I stumbled over an "application ... DC-Relay ..." - the Williams Grand Prix "Delay-Relay". When one of the spinners spins: The Outhole-Relay and the Top Eject-Relay and the left and right Bonus-Relays are hindered to pull-in --- as the pulling Spinner-Relay makes the Delay-Relay to actuate - and the Delay-Relay opens a switch. See the JPG - as an example I show the Top Eject-Relay hindered to pull-in.
The reasoning, justification, argumentation to "Delay-Relay (DC) does not use the full coil voltage" is a bit whacky: We know that on a car battery when discharging the voltage drops , fully loaded, 100% is 12.75 Volts, 50% is 12.25 Volts, discharged is less than 11.9 Volts. The capacitor on the Delay-Relay is a battery finally discharging - so the voltage to the coil on the Delay-Relay drops means "part-time the Delay-Relay does not consume full voltage". Greetings Rolf

Hi
a constructed story --- I like to play my XYZ-Pin - I can make 10 points, 50 points and 1000 points and there are five targets on the playfield I can make 100 points. I do get my 100 points when the ball hits the target "bulls eye shot" - but now and then on a "grace shot" I do not get my 100 points. Why ? Greetings Rolf
