Synchronous Motor Driven

When energized a Program Timer repeats continuously and synchronously, a pre-established sequencing of ON/OFF switching events. Also known as Cam or Multi-cam Timer, Cycle or Re-cycle Timer, or Repeat Cycle Timer. One "cycle" is one revolution of the output cam shaft.

These may be wired for single revolution and stop operation . An external momentary pushbutton wired as shown on Homing will cause the camshaft to rotate 1 revolution only and come to an abrupt halt. During this cycle the cams perform the prescribed sequence of operations. This popular wiring is typified in cup dispensing coffee vending machinery.
