A timer that automatically resets by cutting off the connection with the driver is often called a "self-cutoff" timer. They are a very useful tool in the programmer's "toolbox". The following example is not a complete practical application but is selected to highlight the role of the "self-cutoff" timer.
Emerson CE4001S2T2B4 Controller, Timer T001 runs continuously, and the timer coil is driven by its own normally closed contact. When the timer completes the timing process, the coil is de-energized, making the timer's normally closed contact invalid, thus breaking the circuit and preventing the coil from being energized. This new state also means that the normally closed contact can no longer be energized. Therefore, the final situation is that the timer resets and automatically starts its timing process again. This is a very fast response. The reset/set of the timer occurs within approximately one scan (or at most two scans) of the program. In such a short time, the continuous setting and resetting of the timer cause the timer contacts to act as if they are pulse-excited. Using the normally open contact of timer T001 to drive the ALT instruction illustrates this. Every 20 seconds, the output states of Y001 and Y002 are swapped.
