Hi Playdium
I think the Coin-Lockout-Coil should be called "STOP-CoinLockout-Coil" as it is "Coil nonpulling is routing thrown-in Coins to the Return-Compartment --- Coil pulling is thrown-in Coins can pass through to the Cash-Box (Coin accepted to start a game or step-up up the Replay-Counter).
Example-A: Pin is toggled-off - thrown-in Coin cannot start a game therefore as the Coil is nonpulling: Thrown-in Coin is routed to the Return-Compartment.
Example-B: Pin is toggled-on, a Game has been started - Score-Motor is running for to help a Playfield***-Feature - the Pin is not capable at this time to accept a Coin - then start a game: Thrown-in Coin is routed to the Return-Compartment.
Motor is in Home-Position - Coins can be accepted - Coil is pulling.
Motor is running (busy helping elsewhere) Coins cannot be accepted - Coil is made nonpulling.
Playfield***-Feature - well every feature that hinders the Pin to manage "Coin thrown-in starts a game / steps up the Replay-Counter". Greetings Rolf
