5226; Added Multi-Transitional Safety Stop Input and Logic
Pathfinder

Changes made for Pathfinder 5226 controllers.

It was assumed that the safety stop switch on folding machines would stay on from the safety stop height down to a clamped position. It has been discovered from new safety stop handling that Schechtl models will turn off the switch before reaching a clamped state. Instead of having companies adjust the machines to keep the switch on for the entire move down, a new input function has been added to Schechtl machines to allow the safety switch to turn off before clamping. The new multi-transition safety stop input function allows the machines switch to turn off when it is below half the safety height. For more information refer to:

Up until recently no 5226 board was used on a Schecthl install because the 5223 is a drop in replacement for the Stigmatek controller. The problem is that the machine in question was has a different setup of using 2 separate drives which require more I/O that the 5223 does not have. In previous cases a 5225 was used instead, but apparently we could not get that controller quick enough. So a 5226 was used instead which at the time only seemed that a Pathfinder V5 model configuration was needed. Turns out the Multi-Transitional Safety input needed to be implemented into the 5226. This was accomplished and can now be used on future installs.
