The purpose of the delays are to make sure the motor comes to a complete
stop before trying to reverse, because the motor isn't instant reversing.
Normal settings are about 5 seconds. The old Tri-Ex used a 5 second delay
that looked like a vacuum tube. They operated at 26 Volts. US Tower uses
solid state relays and operate at 110 volts
