Select the number for 'Manual Calibrate'

Navigating Calibration Parameters

Press ENT to move to the next parameter

Press SETUP to move back to the previous parameter

Review the values calculated by the MP300 SERIES

Override values if necessary and document changes

Ensure the following are in place

Stopping Reaction Time Configuration

Enter the STOPPING REACTION time (seconds)

Is the STOPPING REACTION time within the acceptable range (0 to 5.000 seconds)?

Run a test cycle to verify the STOPPING REACTION time

Run ten parts of equal lengths, 120" for example.

Enter the measured lengths of the ten parts.

Calculate the average length by adding up all ten parts and dividing by ten.

Use the formula for the new CORRECTION FACTOR using the average of the ten parts for 'actual measured length'.

Enter the calculated CORRECTION FACTOR.

Is the new CORRECTION FACTOR within acceptable limits?

Record any observations or issues encountered during testing.

Set the SHEAR REACTION time to zero

Disable die boost by disconnecting the wire on the output of the controller

Slow the line speed to avoid metal jamming in the shear die

Press SETUP until the screen in figure 3-5 appears

Select the number for 'Trim Cal'

Length Measurement and Correction Factor Calculation

Enter the programmed length of the last part cut

Enter the actual measured length of the last part

Would you like to update the current correction factor with the new value?

Use CALIBRATE TRIM when part lengths are incorrect but consistent (e.g., all parts 3/16” long)
