Outline Dimensions

Wiring Diagram (Bottom View)

Repeat Cycle: Application of line voltage starts the pre-set OFF-time period

Upon expiration of the period, the output relay is energized, its contacts

transfer, and the pre-set ON-time period begins. At the end of this period

the output relay is deenergized, and a new cycle begins. The OFF and ON

cycles continue until power is removed. To reset the timer, input voltage

must be removed for at least 25 ms.
