START-UP SEQUENCE - Gottlieb 1976 Royal Flush - 4 Player
Inserting a coin or pushing the replay button actuates 'S' relay (Start relay).
This relay will lock-in through its own switch and a motor '2B' switch.
'S' relay starts the motor running.
'AX' relay actuates and the “coin” unit resets through switches on 'U' and 'S' relays and a switch on motor '1D'. 'Q' and 'U' relays de-energize when 'AX' relay operates.
When 'AX' relay actuates, the reset relays 'Z1' and 'Z2' are energized in sequence by rivets on the “Player” unit, through switches on 'AX' relay.
(a) Motor '1A' steps the “player” unit, through switches on 'AX' relay and'P5B' to the 20th position energizing 'Z1'.
(b) When 'Z1' is energized the 1st and 2nd player score units reset to zero through switches on motor '1A', motor '4A' and 'Z1'. When all score units of the 1st and 2nd player are at zero the player unit steps to the 21st position through a normally closed switch on 'Z2' and normally closed switches on all score units of the 1st two players, actuating 'Z2' relay. The 3rd and 4th player score units now reset through switches on motor '1A', motor '4A' and 'Z2'. The player unit continues to its zero position through the closed switches on 'Z1', 'Z2', 'P5B' and motor '1A' until 'P5B' opens.
Inserting additional coins or pushing the replay button will step the “coin” unit to a maximum of 3 (4 players) through switches on 'U' and 'S' relays and a switch on motor '1D'. The replay button circuit opens when “coin” unit is on 3rd position.
Place the ball in the out hole. The ball return switch closes and completes the circuit to 'O' relay through the normally closed switches on 'A', 'AX' and 'Q' relays. 'O' relay locks-in through its own switch and a switch on motor '2B'. When 'O' relay is energized, motor '4C' actuates the ball return coil (which kicks the ball onto the runway) through a switch on 'O' and normally closed switch on 'BX' relay. The ball is now on the runway and is ready to be put in play.
The remaining balls that enter the outhole are kicked across the trough switch which pulls in 'P' relay. 'P' relay runs the motor.
Switches on 'U', motor 2C, 'P', 'BX', and motor 1A advances the 'Player' unit the required number of steps determined by the 'Player' unit switches and ‘Coin’ unit.
