# AN-TMR-021 - Signal Asymmetric Single Cycle OFF

## Timing operation of the Signal Asymmetric Single Cycle OFF Timer function

AN-TMR-021

21\. Signal Asymmetric Single Cycle OFF Timer Function:

Power is applied to the timer during operation. This timer uses two separate time presets. On the rising edge of the signal input, the cycle starts with an off state of the output controlled by the T1 preset. Upon the completion of T1, the output turns on for the duration of the T2 preset. A signal input condition during this on off cycle is ignored. Once complete the timer waits on another signal input and the cycle repeats.
