The guide channels were closed on the bar pusher. The correct process would be to close the channels while the pusher is forward, then retract the pusher through the ring, instead the channels were closed and the front ring guide is on top of the pusher instead of the pusher being inside the ring.

To correctly close the guide channels on the Edge Technologies Series bar pusher:

1. Ensure the material is moved outside of the gripper area so the grippers can close without obstruction.
2. Check that no bar is present in the grippers; if there is, move it forward.
3. Confirm the channel lock system is functioning. The pneumatic cylinder must control the lock mechanism to hold the channel closed.
4. For the 8ft Patriot model, the channel open/close cylinder is used to hold the channel closed, as it does not use the lock linkage.

These steps ensure proper and safe closure of the guide channels.

The first way to correct this issue would be to change the status of the jumper or wire that is controlling the cycle start signal.
  • Page 24 PATRIOT 338/551 Bar feeder on- This signal is typically used as a bar feeder alarm to the lathe. IF the lathe is always receiving the signal that the bar feeder is in alarm it will show a message saying that the bar feeder is in alarm.

IF wired incorrectly this signal can also cause the bar feeder to not allow feeding because the automatic signal is not received. *Needs to be check if wired into the machine interface* To check if this signal is working correctly on the Edge product, put the bar feeder into automatic and check the HMI screen.
  • Page 26 PATRIOT 338/551 Chucker Mode: This setting allows the lathe to run without the bar feeder. When chosen the bar feeder sends an auto mode signal to the lathe while remaining in the manual mode.
