Help with TOF

[wilfin]

I am trying to program a fan to cut off 10 seconds after a motor is shut off.  I am using Trilogi and do not understand how to get a timer to become an off-delay timer.  An example would be greatly appreciated.

Thanks,

Easy!  The following circuits turn on the fan when the "Start" button is pressed.  The fan turns on the countdown timer T1. When T1 times out, its contact will disconnect the Fan.
