Changes made for Pathfinder 5226 controllers.

There are many variations of pedals that can be used on a folding machine. In a perfect world you would have a pedal that is specific to what you would like to happen. As in a clamp down pedal that is used for moving the clamp down at the appropriate time, a bending beam cycle pedal to start a bend operation or even a shear start pedal to start a shear operation. In reality though the machine may have a limited amount of pedals that will do multiple operations. Some of these pedals might have two contacts that allow the user to push through to a different wiring set which can be considered a different pedal. The most common type of a push through is having a clamp up be the push through of the clamp down pedal. This is mainly for safety to make sure the user can quickly push through to a clamp up move when the clamp is moving down. A problem has arouse from this type of pedal with the clamp up pedal now able to return a bending beam or shear if they are in a paused state. The main problem of this is if there is no dedicated bb cycle or shear pedal then the clamp down pedal will switch to those other pedals logic based on which operation you are in. If the clamp down does have a clamp up push through then the return process will be thrown off because the clamp down will restart the operation before the up pedal signal is seen.

The solution to this problem was to have a small delay with the clamp down signal logic being started if the bending beam or shear are not home and in a paused state. The delay gives time for the user to push through and hit the clamp up to return either axes home. If the delay times out before seeing a clamp up then the clamp down logic will take over and the move will resume.
