Micrologix 1500

Here is what I'm doing:
There are these cycles that a machine goes through.
It's variable by the operator, so that is why I have the math, subtract functions on there.
When I am in any of the last three cycles AND B3:20/14 (#14 Draw Vacuum Latch Cycle #14) is activated, I want to turn on the Timing Relay On.
What this will do is Turn on an adjustable True OFF Delay Relay.
The problem is, the OFF Delay doesn't start until power is removed from it's coil.
I need a way the output will only come on once when the conditions are met, and then shut off and be ready for the next cycle.
I don't know what to put in the (Here) area.
I don't know if I am trying to over-simplify the program, or an answer is just over my head on this one.
Thanks
