The Open Loop press DIP switch on the Tube Mill controller was originally not allowed. It is incompatible with the unique scrap handling features that Tube Mill customers are used to. Manual Shear in the Run Mode and the Scrap Chop capability of the scrap sensor input are incompatible with a punch queue, without incuring extra scrap.

We have a customer who needs an output to trigger a non-integrated printer. They currently have an operator standing next to a push button who has been manually triggering it for the last several weeks. They don't care if some of the parts have the message shifted or missing as long as most of them have the message on the part somewhere. This is how the Taleyrand tube mill controller that many customers are used to functions.

The Open Loop Press DIP switch on an XL200CLT (Tube Mill) controller is now allowed. However, there are some differences to preserve the more important Tube Mill features.

All of the scrap handling features were implemented originaly using the Manual Shear In the Run Mode capability. These are the main features that make the tube mill unique and they must be preserved. A Manual Shear in Run Mode ignores the queue during the shear and then adjusts the encoder count to align back to the shear queue.

During a scrap handling event the shear queue and shear work as originally implemented. The press was modified to work like the shear in that it stops processing queue targets while a scrap handling event is active. Once the scrap handling event is over and the shear has adjusted the encoder count to line up with the queue, the press begins processing targets again. The press will never report a missed target. It will delete the target from the queue and move on to the next one.

To keep the operation of the machine as close to shear only operation as possible, the queue is not maintained when exiting the run mode. During Queue initialization no scrap is added to eliminate negative targets. The negative targets are removed.

Normally enabling a press also enables extra Setup paramaters that will not apply. Scrap Part Length and Scrap Part Mode parameters are disabled. The Front Shear Tool parameter is disabled.
