PLC CONTROLLER

Pre-Run Sequence:
1. Jog the material forward using the manual FWD JOG or MICRO buttons
on the Home screen or the JOG switch at the entry end of the machine.
The material must exit the shear and be detected by the panel detection
sensor.
2. Shear the material using the Shear Cycle button. At that point, the
machine will be fully loaded with material, the length counter will be reset
and the controller will be ready to run in automatic mode.
If the machine goes forward or reverse and the encoder does not detect movement, the
pre-run sequence will be reset and the controller will not run in automatic mode. This
would happen if the material was cut at the entry end of the machine at the end of a job or
at the end of a coil. This could also happen if the encoder did not have proper tension on
the material.
Job Entry
Jobs can be programmed to run automatically. From the Home screen, press the Job
Entry button to enter the Job Entry Screen.

Enter in the quantity of parts to run and the length of the part.
Specify if the machine will pause at the end of job. If Yes is selected, the machine will
stop after the job is done running. The user can then press Start to run the next job or
return to the Job Entry. If No is selected, the machine will run the current job and
automatically start running the next job. If yes is selected and there is no job
