Example 11: The open/close delay circuit is composed of two timers; output Y4 has a delay no matter 
input X0 is ON or OFF.

Example 12: Extended timing circuit   
In the circuit in the ladder diagram on the left, the total delay time from the moment input 
X0 closes to the time output Y1 is electrified is (n1+n2) × T, where T is the clock cycle. 
The timers are T11 and T12, and the clock cycle is T.
