The most requested and used sequences are shown below. Almost any desired sequence can be constructed. "Cycle" refers to the time required for the flashing action
to go through its complete performance and start to repeat. "Time of Cycle" is expressed in seconds. "Circuit" refers to the current controlled by one cam and one set
of contact points. The time on for a circuit is indicated by an "X" in the box, time off is indicated by a blank box.
