The 24 volt AC power connection for the machine is on
the circuit board of the coin mechanism. The terminal
block for incoming power is located on the lower left
corner of the circuit board. You will have to lift up the
cover/instruction sheet to locate this black terminal
block, which requires a small slotted screwdriver for the
2 lugs. Leave at least 24” of wire inside the vender to
simplify future coin mechanism programming.

EQUIREMENTS
The minimum power required for each vender is 1/2
amp (500mA). To run multiple venders on a transformer
first determine the total amperage required, taking into
account future additions. To determine the amperage
output of a 24 volt transformer that is given in VA, divide
the VA output by 24. For example, a 100 VA transformer
would provide 4.2 amps (100 ÷ 24) of 24 volts AC
power. This would be ample power for 8 venders.

NSTALLATION
Packed inside the carton pad at the top of the vender:
• 1 – Cabinet hangar bracket
• 1 – Bag of fasteners for the security frame
• 1 – Side bar - mounts on right side of cabinet
Mount the hanger bracket securely on the wall and note
that the top edge of this bracket will go inside the open
area at the back of the cabinet. Two people should lift
the vender to hang it on the bracket. Open the door and
note the two 3/8” diameter mounting holes in the lower
left and lower right sides of the cabinet. Remove the
coin mechanism to expose the right side mounting
holes. To remove the coin mechanism, first unplug the
white ribbon cable from the red switch pad and then
loosen the two mounting screws (you do not need to
remove these screws) and lift the coin mechanism
upward to detach. There are two wire harnesses to
unplug from the back of the coin mechanism. Now
select desired mounting holes and mark the holes,
remove vender, drill and install appropriate anchors.
Re-hang the vender and secure the lower fasteners.

OADING
The shelves can be easily and quickly reset into the vend
position (horizontal) by running a finger or thumb up the
shelves from the bottom to the top. This ‘fanning’ will
take only seconds to reset all shelves. When loading any
column, if there is not enough product to fill all 24
shelves, then load from top down. This insures that the
sold-out switch will activate when the last shelf (the top
shelf) drops. If a customer chooses a selection that is
empty, the display will flash & and return
the inserted coins.

HOOTING
LED display out: power loss, check for 24 volts (+ - 15%)
at the terminal block of the Circuit Board. Power down for
5-10 seconds and power back up. If the display is still out
then simultaneously press the UP & DOWN buttons on
the Circuit Board to clear any error codes. If this fails the
Circuit Board is in need of repair.
LED display is not alternating: this indicates a short in the
Switch Pad or the Ribbon Cable. First, disconnect the
Ribbon Cable from the Switch Pad and if the LED display
returns to alternating, the problem is a short in the Switch
Pad. If the display still is not alternating then unplug the
Ribbon Cable from the Circuit Board to check if the short
is in the Ribbon Cable. Call the factory for information on
how to disable a shorted switch, which will get the
machine back working, less the bad switch.
Inserted coins rejected: power loss, MA800 acceptor
needs reprogramming, wrong type of coin inserted, accep-
tor not plugged into back of circuit board, change sample
coin in Slugbuster. If a column is sold out or the exact
amount was not inserted, then coins will be returned to the
customer after a selection button is pressed.
displayed: a vend motor for a column is not
working properly. To reset and test, simultaneously press
the UP & DOWN buttons on the Circuit Board. If this fails
then remove the column from the machine and visually
inspect the motor and wiring. The motor may be out of
alignment or lubrication may be needed between the
motor cam and the shelf flanges.
displayed: the coin cup motor is not working
properly. Remove the Coin Mechanism to visually inspect
the motor for coin jams, etc. The coin cup can be manu-
ally rotated to test its operation. To reset and test, simulta-
neously press the UP & DOWN buttons on the Circuit
Board until CLR appears on the display. Powering down
& up will reset the coin cup in the upright position.

ESSAGES
• There is a problem with the vend motor
assembly of a column and this column will not function. If
this selection button is pressed after coins have been insert-
ed, the coins will be returned to the delivery tray. The other
columns will not be affected.
• There is a problem with the coin-cup motor
(the escrow cup) and the machine will return any inserted
coins until the problem is resolved.
To clear any error messages, either press the UP & DOWN
buttons simultaneously and wait for to appear on
the display or power down the machine for 10 seconds
and power back up. Refer to the trouble shooting section
to correct the problem.
