I figured out which configurations produce the other three bell patterns:
Bell isn't wired through X relay or gate motor:
Bell sounds continuously.
Wired through X relay only:
Bell sounds from startup to just before gates rise.
Wired through gate motor only:
Bell(s) sounds when gate(s) are in motion.
You never wire anything to a "gate motor".
Ringing continuously is wiring the bell straight to the GP circuit. -Takes no brains to do that. Whenever the lights flash, the bell rings. Not a good practice. Leaves a bell ringing all the time, which is unnecessary, and promotes complacency.
Ringing "in motion" is through the GP, but broken through the mech. contacts. -Takes a slight bit of effort to do, but you get a bell start to ring when the gates rise, which is unsafe.
Ringing only upon activation, and while the gates lower, and cutting off and not ringing again until another activation, is through the X relay, broken through the mech contacts. ...This takes a little brains to do, but is the intelligent way to do it, as when you hear a bell ringing, you know a gate is about to come down, clear the crossing.
