Description

EN

Make clock pulse generator ON and OFF via Input EN (Enable).

R

Make Output Q be 0 via Input R (Reset).

T

T is the time length of output to be ON and OFF.

Q

Every time EN changes from 0 to 1, the internal timer begins to time, and when Time T is up, the output is 1. If EN is held on 1, timing can be started again, and when Time T is up again, the output is 0. The cycle operation is continued in this way until EN is 0 and Output Q is 0. When R is 1, then the output Q is 0. And when R changes from 1 to 0 and EN is 1, all the initial status of Q changing from 0 to 1 will start its cycling changed.

Time sequence frame is as follows:

Notes:

-Use Parameter T to set ON/OFF time; The assignment range of T is 0.01 ~ 99. 99, and the time units can be set respectively to hour (H), minute (M) and second (S). The time accuracy can reach 0.5 /00 Second.

-Input EN( Enable) enables clock pulse generator to work. Output Q of clock pulse generator will flip-flop the status every time the time T elapses, and cycle operation is continued in this way until Input EN (Enable) is 0 and the clock pulse generator stops operation and Output Q is 0.

-This function is applicable to generate pulse automatically and to switch ON/OFF automatically.
