Advice:

Time window infinite between channel 1 and channel 2 via jumper between X3/X4 and T33/T34. For external reset connect reset button to X3/X4.

T 33 X3

Start with trailing edge function. Module is activated after release of the reset button. This prevents tampering of the reset button which could lead to an automatic reset.
