Series Description:The TSD3 has a unique function of ON/OFF recycling with ON time always equal to the OFF time. When time delay is changed by the potentiometer, both the ON and the OFF periods change exactly.
Operation:(Recycling Flasher - ON Time First) 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. Reset: Removing input voltage resets the output and time delays, and returns the sequence to the T1 ON time.
