Operation (Percentage): Upon application of input voltage, the output energizes and the T1 ON time begins. At the end of the ON time, the output de‑energizes and the T2 OFF time begins. At the end of the OFF time, the output energizes and the cycle repeats as long as input voltage is applied. Increasing the ON time decreases the OFF time. The total cycle period is equal to the ON time plus the OFF time. The total cycle period is factory fixed. ON time range is 1 to 99 percent of cycle period. Reset: Removing input voltage resets the output and time delays, and returns the sequence to the T1 ON time.
