Vend Motors
Two types of motors may be used with this vendor. The
configuration of the machine will be different if all of one or
another is used, or if there is a mix. Sensit 3 (or simply
S3
)
software can be used to best advantage using motors designed
for homing, but it can be set to control motors without the home
switch feature. Motors may be mixed throughout the machine, but
each tray
must
have all motors of the same type.
The vend motors are snapped into mounting holes on the back of
each tray. The motor is driven by 24 VDC through a harness from
the control board. (See
VENDOR PREPARATION and
INSTALLATION
on page 13,
MOTOR POSITIONS
on page 18
and
HELIX HOME POSITION
on page 19.)
Sensit 3 Vend Motors
The Sensit 3 (or simply S3) vend motors have a plastic case of
which the rear half is blue. S3 coupled motors can replace dual
helix ‘butterfly’ motors. Where a dual helix motor is used, replace
it with a 23007 motor (having a blue and ivory case for CCW
rotation) and a 23007-01 motor (having a blue and gray case for
CW rotation) and reinstall the helices. Use Tray Setup in Service
Mode to couple the motors in each column together, causing them
to turn at the same rate.
Coupled motors will always be stopped when either one reaches
the home position. If one motor runs slightly faster, the slower will
then be individually driven to its home position. Depending on
motor configuration, the motors may jog twice during vend cycles
to try to dislodge hanging product.
Note:
When
not
in Service Mode, and with door
open
, press
#
to reset all switched motors to Home position - not
applicable for non-switched motors. (See
TRAY SETUP
on page 23.) Motors already at home will not move.
Sensit II Vend Motors
A Sensit II (or simply
S2
) vend motor has a plastic case which is
all ivory in color. A dual helix S2 motor has a larger “butterfly”
gearbox allowing two helices, one for CW and another for CCW
rotation, to be installed. The dual helix housing only allows helices
to be adjacent to each other.
These motors have no home switches and have been
discontinued and replaced with S3 vend motors. However, the S3
Control Board can be set to accommodate these motors. (See
TRAY SETUP
on page 23 for details on changing motor types.)
Helices
There are four sizes of helices available, approximately 1 1/2”,
2 5/8”, 3”, and 4” in diameter. There are several pitches available
in each size, and is determined by counting the number of product
openings in the helix.
(See
CHANGING HELICES
on page 18,
MOTOR POSITIONS
on page 18 and
HELIX HOME POSITION
on page 19.)
Dividers
The dividers separate product columns on the tray. To remove the
divider, push rearward and lift. To install, insert the rear tab in the
desired slot, push rearward and then down. Make sure the locking
tabs on the bottom have engaged their respective slots and pull
forward. Bottle tray dividers are held in place with rivets.
Candy Pusher Bar
On snack trays, 2 horizontal slots in the divider allow for the
installation of a candy pusher bar. The candy pusher bar keeps
items pushed to one side of the column. This is typically used with
tall and narrow products. The candy pusher bar is removed by
pulling the bar free from the plastic clips. To reinstall, it is easiest
to squeeze the bar into the clip using pliers (See
CANDY
PUSHER BAR INSTALLATION
on page 19).
ELECTRICAL PANEL
Power Switch
The power switch is located on a panel inside the cabinet below
the sliding dashboard panel and beside the coin box. The power
switch is used to disconnect 24VAC power to the control board.
Note: The power should be shut off when MDB
devices are being connected or disconnected, when
the board is being serviced, or before any wiring
harness is connected to or disconnected from the
control board or sensors.
Fuse Holder
The fuse holder is located on the panel just below the power
switch inside the lower right rail mount. It contains a 3 amp fast-
blow fuse to protect the 24 VAC power supply to the control
board. A spare fuse is stored in the cover. The fuse holder is
opened by pressing back on the indicated side of the cover and
pulling out.
Transformer
The transformer reduces the input voltage to 24 volts AC for the
control board. It is located beneath the cover which protects the
power switch and fuse holder.
RFI Filter
The filter removes electrical noise from the power supplied to the
24VAC transformer to prevent interference with operation of the
control board and software. It is located next to the transformer, or
at the rear of the cabinet (220V)
Ground Attachment
The vendor electrical ground is made through the use of
grounding studs or screws at the lower back wall of the right rail
mount. Earth ground and individual ground wires from the high
voltage components are attached here,
and should always be
replaced after service or repair.
