The suction length adjustment keys allow the user to
change the amount of suction applied to the current sheet
length. The display shows the percentage in 5% steps. All
of the bars must be totaled to get the value. The range of
adjustment is 5% to 50% of the current sheet length. If the
suction length is manually adjusted while the Learn Mode
LED is on, the suction length will no longer be the Single
Sheet suction length of 6.0". The new suction length will
be based on the current sheet length and suction setting.

These keys toggle between automatic control and cycle
mode. In the cycle mode, the suction valve will be on for
the suction length and off for the remainder of the sheet
length plus the gap length. No adjustments are made for
slipped sheets or process changes. The automatic mode
corrects for process changes and controls the timing of the
suction valve to maintain the user-selected gap. If the gap
is less than 1.5" (4.0 cm), the right hand decimal point of
the small display (2) will flash and the Leading edge
control will be active. If the gap is greater than or equal to
1.5" (4.0 cm), full Leading and Trailing edge control is
maintained. Refer to table 10 for suction mode symbol
definitions.

is desired, the value may be overridden with the suction
length adjustment keys. The sheet length range is 10 cm /4
inches to 250 cm / 98.5 inches.
