Caution: This vending machine utilizes DC motors. Do not attempt to turn augers by hand. Motor damage could occur.

 

The vending sequences is "first-in, first-out" for each selection, eliminating the need for stock rotation to maintain fresh products in the vend area.

 

This manual should be read thoroughly to become familiar with the functions of all components, along with the features that are available. The initial set-up of a vending machine is very important in insuring trouble-free operation of the equipment. Following the instructions at the initial installation of the machine will avoid service problems and minimize set-up time.

 

UNPACKING 

 

This vending machine was thoroughly inspected before leaving the factory and the delivering carrier has accepted this vending machine as their responsibility. Any damage or irregularities should be noted at the time & delivery and reported to the carrier. Request a written inspection report from the claims inspector to file any claim for damage. File the claim with the carrier (not the manufacturer) within 15 days after receipt of the vending machine. Carefully remove the outside packing material in a manner not to damage the finish or exterior of the vending machine. Inspect the vending machine for concealed shipping damage. Report any damage hidden by the shipping material directly to the delivering carrier on a Hidden Damage Report. Remove the "Knock-Away" support by sliding a pallet jack under the vending machine, inserting a screwdriver or prying tool into the groove of the Knock-Away and splitting it in two as shown in Figure 1. Turn the leveling screws in as far as possible.

INSTALLATION 

 

Consult local, state and country codes and regulations before installing the vending machine. Please refer also to the Safety Manual & Installation Guidelines (P/N 4206816) supplied with your vending machine.

 

Caution: To insure reliability and maintain manufacturer's equipment warranty, vending machine must NOT be placed in and environment where the temperature is greater than 100F/37.8C and the relative humidity is 65% greater.

 

Warning: DO NOT USE EXTENSION CORDS. Extension cords can cause problems.

 

1. Position the vending machine in its place of operation no further than 6 feet (2 m) from the power outlet or receptacle.
2. Leave at least 6 inches (15 cm) of space between the back of the vending machine and any wall or obstruction for proper air circulation.
3. Retrieve the keys to the vending machine from the coin return cup.
4. Open the vending machine door and remove all internal packing material.
5. Check that the vending machine door will open fully without interference.
6. Level the vending machine. Make sure all levelers are touching the floor. The vending machine must be level for proper operation and acceptance of coins through the coin changer. When the vending machine is level, the door can be opened to any position and not move by itself. Try the door half closed, straight out and in the wide open position before deciding that the vending machine is level.

 

GROUNDING (EARTHING) & ELECTRICAL
Please refer to the Safety Manual & Installation Guidelines (PIN 4206816) supplied with your vending machine. Before connecting the vending machine, the integrity of the main electrical supply must be checked for correct polarity, voltage, (earth) ground, and (amperage) circuit protection. It is recommended that these checks be repeated at 6 month intervals alon9 with the routine safety electrical testing of the equipment itself. Consult a qualified electrician to correct negative voltage, amperage, polarity, or ground (earth) checks. For proper operation of any equipment utilizing electronically controlled components, the
equipment should be placed on an isolated or dedicated noise-free circuit. A noise suppressor has been installed in this machine to compensate for any signal noise that could interfere with the normal operation of the controller.

 

Power Switch 

Each vending machine is equipped with a power switch located on the transformer panel along with a 3 amp breaker. The witch will shut-off the light and controller. See Figure 2. The 3 amp breaker is protection for the transformer.

LOADING SNACKS 

 

1. Lift the front of the tray slightly and pull forward slowly until the tray stops. 2. Lift the front up and pull forward one inch and allow tray to tilt down all the way to loading position.
3. Load products from front to back, making sure all items fit freely between the augers. Do not attempt to force oversize items or packages into the spaces. Do not skip a space.
5. Place the product on the bottom of the compartment on the product augers, with the label facing the front of the machine for easy identification by the customer. See Figure 3.
6. When finished loading the tray, use both hands to lift the front end of the tray so that it is slightly above horizontal and push it back slightly to let the rollers clear the rear ramp detent. Let down to horizontal position.
7. Push it back into the cabinet until it ramps into the front ramp detent and stops. All trays must be pressed to the rear of the cabinet and properly seated in the detent position.
8. Tray is ready for vending. Repeat steps as necessary to other trays.

 

The size of the item being vended must be larger in diameter of the auger being used. Undersize items could cause vend problems. If the product does not fit the auger properly, use a different pitched auger or appropriate product spacer. See the following table for augers available from your distributor or service entity.

 

Vending Machine - Loading Snack Products 

 

Product Ejectors 

Product ejectors can be added to the end of the augers to help move the product out of the tray area (see Figure 4).

 

AUGER TIMING
Difficult to vend items can be dispensed more dependably by retiming the augers. Each auger can be rotated in 200 degree increments, changing the auger position for a different drop off point at the front of the tray. Most items can be vended successfully when the auger end is positioned at 6 o'clock. For dual drive augers, the ideal timing is for the auger ends to meet at the center of the tray: left auger at 3 o'clock, right auger at 9 o'clock. If you have trouble vending odd sized or odd shaped items, auger retiming can be accomplished on a trial and error basis as follows:

1. Disconnect power before servicing.

2. Pull the tray containing the auger to be retimed forward to its stop.

3. Remove products from the tray.

4. Remove the motor cover.

5. Raise the motor slightly and pull forward on the auger until it separates from the motor. See Figure 5.

6. Rotate the auger to the desired position and reinsert the auger coupling into the motor.

7. Position the auger coupling so that it is seated over the vertical rail or retaining rib on the tray.

8. Replace the motor cover and securely tighten.

COIN CHANGER & DOLLAR BILL CHANGER 

 

Caution: Do not plug in or unplug the coin changer with the power on!

 

The controller will monitor the condition of the coin changer at all times. Any activity (coins inserted) will be recorded and stored in the controller.

 

REMOVING ACCEPTED BILLS
Accepting bills may be removed by opening the "bill box" lid or by removing the bill box from the validator. (See manual from validator manufacturer). If the bill box is removed, make sure that it is fully latched in place when it is returned to the validator.

CLEARING JAMS & CLEANING
Trapped bills, debris or dirt can result in poor bill acceptance or bill rejection. Remove the bill box and lower housing to clear trapped bills or debris. Clean the bill path plastic parts or belts with a cloth moistened with a mild soap and water solution. Clean the magnetic head and optic sensor using a swab and isopropyl alcohol. See manual from validator manufacturer.

 

Caution: Do not use any petroleum based cleaning solvents, scouting pads or stiff brushes for cleaning.

 

CONTROLLER 

 

There are two modes of operation: Sales Mode and Service Mode.

 

SALES MODE
This is the default mode when the machine is turned on. The vending machine accepts deposits, pays out change, and dispenses products to customers. The 10 character scrolling display is used to communicate with the customer.

DISPLAY CREDIT
When credit is deposited, the amount (up to five digits) is displayed.
If the payout tubes in the coin mechanism are below the low-level sensors, the message "PLEASE INSERT EXACT MONEY" will scroll on the display.

MAKE SELECTION
When a selection is made and the accumulated credit is less than the selection price, then the price is displayed for one (1) second followed by the message "PLEASE INSERT MORE MONEY".
When a selection is made and the accumulated credit is greater than or equal to the price of the selection, then a vend attempt will take place.

VEND CYCLE
Selections A thru C have been assigned at the factory to be monitored for iVend optical sensing.
They will have an associated vend operation that differs from the normal vend operation.
For 5 milliseconds (5 msec.) at the start of a vend, the iVend optical sensor will be checked for blockage. If blocked - the normal home-switch-vend cycle will be used and the optical sensors will be ignored. Both the vend motor and a 9 second vend timeout timer are started.
The selection motor rotates to the home-switch position.
If there is a home-switch signal, then the vend is considered successful.
If after 9 seconds and there is no home-switch signal, then the vend failed. The vend motor is shut down and the message MAKE ALTERNATE SELECTION" is displayed. The customer can press the selection buttons to activate this or another motor or press the coin return button.

NOTE: Force vend is overridden under this vend cycle.

If not blocked - the iVend Sensor System is used. The vend motor and a nine second (9 sec)
vend timeout timer are started.
The selection motor rotates to the home-switch position.
If a product is detected during this time period, then the vend is considered successful.
If after reaching the home-switch position and a product is not detected, then the vend motor will pause for I second while the controller continues to monitor the optical sensor for product delivery.
If a product is detected during this pause, then the vend is considered successful.
If a product is not detected, then the controller initiates a second vend cycle and a 9 second timer while continuing to monitor the optical sensor.
If a product is detected during this second cycle, then the motor will be stopped immediately. The vend is considered successful. The 2ND VEND counter is increased by one.
If a product is not detected and the motor reaches the home-switch position or if a 9 second timer runs out, then the vend has failed or the selection is sold out. Such a state will trigger the display of the "MAKE ALTERNATE SELECTION" message. The amount of credit is displayed. The customer can press selection buttons to activate this or another motor, or press the coin return button.

 

All motors are reinstated to operative mode. The exception is when the OPTICS mode is enabled and AUTOREINST is inactive for the particular selection and no product is detected by the optical sensors. The controller will prevent further attempts to vend the particular selection until the selection's sold out error status is cleared by running a test vend of that selection. See the TEST VEND section of this manual.

CREDIT & COUNTERS
After a successful vend:
The amount of remaining credit will be displayed until all coinage is paid back.
The HIST COUNT (total vends count) will be incremented by one (1) and the HIST CASH (total cash count) will be incremented by the price of the vended selection. The counter rollovers occur at 79,999,920 and $99, 9999.95 respectively.
If a product is detected during the second vend cycle, then the 2ND VEND record counter is increased by one.
The RES COUNT (re-settable vend count) will be incremented by one (1). The RES SALE (re-settable total cash value) counter will be incremented by the price of the selected vended. The counter rollovers occur at 79,999,920 and $99,999.95 respectively if never reset. The counters are viewable in the accounting menu as well as through a DEXIUCS download. Refer to the 120 Select Programming Manual (P/N 4212619) for additional information on DEXIUCS fields.

 

NOTE: Test vends are not included in the counter totals.

 

SERVICE MODE 

The service mode is used by the operator to change program settings and service the machine. The display is used to communicate with operator. To enter the service mode, push the service mode button once. The service mode button is located on the control cover. See Figure 7. If credit exists when entering the Service Mode, it will be restored when the machine is returned to the Sales Mode.

 

NOTE: If credit exists when entering the Service Mode, then it will be restored when the machine is returned to Sales mode. While in Service Mode, the controller will automatically exit back to Sales Mode if no key is pressed approximately 25 minutes.
