1 Be sure that the Cut On/Off button is OFF.

when the LED next to it is lit. Each time you press Select the control activates
the next available mode. Continue pressing the Select button until you get the
mode you want. Then go on to the next step.

Press the Set button. Use the adjustment arrows to change the number listed on

• For Timer Mode: Use the Set button and Adjustment arrows to change
the time (in seconds, to three decimal places). NOTE: the decimal point
cannot be moved.
• For Encoder Mode: Use the Set button and Adjustment arrows to change
the cut length. If the cut length does not equal the set length, adjust the
prescale value.
See Operation Section entitled, Encoder Area.
• For Product Mode: Use the Set button and Adjustment arrows to change
the hold-off time. In Product mode, the desired length is set by the electric
eye that sense the end and initiate a new cut. To prevent unwanted double
cuts, a hold-off (or one-shot) timer is built into the cutter control. After a
cut is made, the hold-off time displays in the Display window (in seconds,
to three decimal places) and begins counting down to zero. No cutting
occurs until the countdown is completed. Make sure the new value is less
than the time between cuts. NOTE: 70-80% of the expected time between
cuts is recommended.
• For Flywheel Mode: Use the Set button and Adjustment arrows to
change the cutter blade speed. If you are not sure what blade speed to use,
start fast and work your way down to slower speeds.
See Appendix B: All
About Cutter Blades
.
• For Follower Mode: Press the Blade Speed button; use the Adjustment
arrows to enter the number of blades (1, 2, 4, or 8). Press the Set button to
accept the value. Use the Set button and Adjustment arrows to set the cut
length.
