About the TSG Repeat Cycle-ON Time First Solid-State Output: Application of voltage to the input of the timer energizes the load and initiates the ON time. Upon completion of the ON time, the load de-energizes and the OFF time begins. Upon completion of the OFF time, the load energizes and one cycle is completed. This ON/OFF cycling continues until voltage is removed from the input. The ON/OFF time periods are independently adjustable.
