Changes made for Pathfinder 5226 controllers.

Thalmann folding machines use a single laser protection system on most of their machines. A certain logic was created by them for how they want the machine to work based on the laser. The basic concept is if the laser is broken while the clamp is moving down or already blocked a timer will start once the foot pedal has been released. During this timer delay the clamp down pedal is locked out and can't move the clamp down. Once this timer is finished another timer will start and in this window the user can press the pedal to move the clamp down in a overridden state. If that timer elapses then the override timers will all start over.

To control these timers parameters 732 Clamp Laser Lockout Delay and 733 Clamp Laser Valid Move Delay are used to control the respective timers.

Changes made for Pathfinder V4 and V5.

Added V4.04.14 for rev B,E and F boards. V5.00.13 on rev G boards.

Changes made for Pathfinder V4/V5 and 5226 controllers.

A shear is an additional option on some folding machines that can be used to cut material at certain lengths. This type of axis is usually automatically controlled. Some shears on machines are now setup to be used manually by an operator. This is done by having the shear locked into a position on top of the machine instead of on the left or right parallel to the clamp surface. When the operator wants to use the shear they can bring it down from the top and latch it onto the clamp surface. It can then be moved back and forth by the operator manually to cut the material.

For more information refer to SCN 4555 5226; Added Manual Shear Logic.

The original implementation still used the old logic that if the shear is on it's home limit the bending beam can move. Based on how the machine is mechanically this is no longer the case and the shear must be on its parked position to move the bending beam. To handle this Error 397 Manual Shear Must Be Returned to Park Position was added to the controller and Pathfinder UI. The controller will not let the bending beam move unless the shear is on its parked limit and if not this error will be thrown.

One logical problem that was originally overlooked is that the bending beam can not move when the shear is not in its upright/parked position. The clamping beam on the other hand is allowed to move if the shear is on its down home limit. With the clamp able to move with the shear home limit on it allows the operator to use the slitter mode in Pathfinder that does multiple shear steps in a row. So if the next operation is not another shear operation to account for slitter mode then the shear must be returned to its park position to allow the next step to use the bending beam. If the shear does not get to the park position and a confirmation pedal does not occur then the system will never continue on to the next step.

Thalmann folding machines have a specific clamp laser logic that was implemented into the 5226.

SCN 4886 - 5226; Added Thalmann Clamp Laser Logic

One piece of logic that was not implemented originally though was if the lockout timer has not expired and the clamp down/next step pedal is pressed then the system will not allow movement. Once the pedal is released the lockout starts again and the same rule applies. If the timer does elapse then the override timer phase will start and if the user presses the pedal during this time the clamp will be allowed to move down in slow.
