Changes made for Pathfinder 5226 controllers.
Some Jorns double folding machines have a hydraulic gripper manifold to control 3 separate types of grippers. The limit switches for the grippers are monitored by their pressure reading through sensors. One problem that has surfaced from this is that when moving one type of gripper it will dip the pressure reading on another gripper type. This will make the sensor dip below a threshold and say the nonmoving gripper limit is now off. This quick dip will make the controller throw an unexpected gripper state since the gripper wasn't moving.
To combat this the input function monitoring each gripper limit will ignore an off state if the failing gripper is not moving and if one of the other grippers on the manifold is moving. This is the first try and will need more on site testing.
