•
After 5 seconds, the output (must continuously provide input signal) will delay turning on after a set time period for the output to operate.
•
OUT 5 seconds, off 5 seconds, flashing on and off alternately when input signal is applied (input signal must be continuously applied).
•
Out 5 seconds then off (must continuously supply input signal) output operates on set time interval.
•
There is an input signal, Out for 5 seconds then off, the input signal is off, Out for 5 seconds then off (must continuously supply input signal), the output operates for the set time then off until the input is no longer there, then the output returns to operating for the set time then off.
•
After 5 seconds, it is out. If the input signal is cut off, the out will still work for another 5 seconds before turning off. (delay on and delay off).
•
Out will operate when there is a start input signal, and will always operate as long as the input signal is still there. When the start input signal is turned off, that is, when the button is released, Out will still operate until the set time of 5 seconds is over, then it will turn off.
•
After 5 seconds it goes out. Pressing the start button again still doesn't reset the time.
•
OUT 5 seconds, off 5 seconds flashing on and off output alternately.
•
Out 5 seconds then turn off, press start button again to reset time. The output operates on the set time, that is, the set number of seconds, the output operates for that number of seconds.
•
After 5 seconds, it's out. (still delay mode but this time you can press the start button again to reset the time.2.7. Applications of LT4S Timer
