AMS SENSIT 3 GLASS FRONT VRM
L0086, Rev. H
3-3
S3 software can be used to best advantage if all motors
are for S3.
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 (Refer to
Sections 4.2.4, 4.2.5 and 5.10).
3.7.1.1 S3 Vend Motors
The S3 vend motors have a plastic case of which the
rear half is blue. S3 coupled motors can replace dual helix
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 stop at the home position after
one revolution of the helices (regardless of S3 option
setting): if the product has entered the hopper the credit is
taken, and if the product has not entered the hopper the
display will read “Please Make Another Selection”. The
same selection or another may be made.
3.7.1.2 SII Vend Motors
A Sensit II vend motor has a plastic case which is all
ivory in color. A dual motor allows two helices, one for CW
and another for CCW rotation, to be installed. The dual
motor housing only allows helices to be adjacent to each
other.
3.7.2 Helices
There are typically three sizes of helices in a
merchandiser, approximately 2 5/8”, 3”, and 4” in diameter.
There are several pitches available in each size. The pitch
is determined by counting the number of product openings
in the helix (Refer to Section 1.3.8 and also in Sections 5.6
through 5.10.
3.7.3 Dividers
The dividers separate product columns on the tray.
Two horizontal slots in the divider allow for the installation
of a candy pusher. 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.
3.7.4 Candy Pusher Bar
The candy pusher bar keeps candies pushed to one
side of the column. This is typically used with tall candy
bars. 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 (Refer to Section
5.15).
3.8 ELECTRICAL PANEL
The electrical panel is located in the recess formed by
the right rail mount on the right side of the cabinet, behind
an access panel.
3.8.1 Power Switch
The power switch is located on the side of the right rail
mount near the fuse. The power switch is used to
disconnect 24VAC power to the control board.
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.
3.8.2 Fuse Holder
The fuse holder is located on the side of the right rail
mount near the refrigeration unit power outlet. 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 in and down on the
indicated side of the cover and pulling out.
3.8.3 Transformer
The transformer reduces the input voltage to 24 volts
AC for the control board.
3.8.4 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.
3.8.5 Relay
The relay uses a 24 VDC signal from the control
board to close the relay and supply power to the
refrigeration unit.
3.8.6 Ballast
The ballast provides the necessary power to the
optional fluorescent lamp or lamps in the door.
3.8.7 Power Distribution Harness
The power distribution harness splits the incoming
power into individual leads for the high voltage
components.
3.8.8 Ground Attachment
The merchandiser 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.
3.9 1.5” HELIX TRAY (OPTIONAL)
The 1.5” Helix Tray is mounted below the bottom
snack tray. To load the tray with small products such as
gum and mints, grasp the tray and pull forward to unsnap
the catches. After loading, push the tray to the rear until
the catches snap in place.
The motors in the 1.5” Helix Tray operate in the same
way as snack or bottle tray motors (Refer to Section 5.16).
