STEP 8:
Checking Material
Discharge from Feeder
IMPOR TANT
Make sure rollers on vacuum base are raised in
the highest vertical position so that it does not
interfere with the material.

Using the two-wire interface cable supplied for vacuum base applica-
tions:
1. At the feeder, connect external run input cable to feeder using
the two-pin threaded connector on the control panel.
2. At the vacuum base, open access door at end of the lower
enclosure to locate start/stop control circuit (Figure 2-6).
3. Route external run input cable from the feeder to this area.
4. Determine the exact run input voltage required by checking
the label on the run input cable.
5. Interface the two bare wire leads at the opposite end of the
interface cable to the vacuum base start/stop circuit. This
involves splicing the black wire and red (AC, DC or dry con-
tact) wire to the start/stop circuit.

Gaining Access to Vacuum Base Start/Stop Circuit
As material leaves the feeder gate cylinder, the trailing edge must be
under the hold-down as the leading edge is entering the vacuum base
transfer section. In otherwords, there must be a good transfer of mate-
rial from the feeder hold-down to the vacuum base transfer section.
To verify:
1. Slide feeder back far enough to clear the vacuum base side
guides. If necessary, loosen the knobs on both side guides and
pull to the outside slightly to allow movement of the feeder.
2. Insert a piece of material under the hold-down in such a way
that approximately 2/3 of the leading edge is extending out
beyond the feeder (Figure 2-7).
3. Slide feeder back into position, making sure it is again cen-
tered between the side guides. As you do so, also make sure
that the leading edge of the material moves into the transfer
section of the vacuum base unobstructed.
