Default Williams EM "lock relay"

Williams triple action. what's the lock relay do? it's always energized when the game is on. is this normal? just concerned about burning it out.

The lock relay does stay pulled in while the machine is on. Itís function is to complete the circuits to playfield lights, head lights, power to solenoids, and has a N.C. switch that when the lock relay pulls in it sends a pulse to the game over relay, so in the middle of playing a game if you turn the machine off then on it will go to game over instead of resuming game play. Since the relay is on all the time itís coil will burn out over time. When shopping out a machine, a new lock relay coil should be on your parts order.
