A COMMITMENT TO SAFETY

SandenVendo America, Inc. is committed to safety in every aspect of our product design.

SandenVendo America, Inc. is committed to alerting every user to the possible dangers involved in improper handling or maintenance of our equipment. The servicing of any electrical or mechanical device involves potential hazards, both to those servicing the equipment and to users of the equipment. These hazards can arise because of improper maintenance techniques. The purpose of this manual is to alert everyone servicing SandenVendo America, Inc. equipment of potentially hazardous areas, and to provide basic safety guidelines for proper maintenance.

This manual contains various warnings that should be carefully read to minimize the risk of personal injury to service personnel. This manual also contains service information to insure that proper methods are followed to avoid damaging the vendor or making it unsafe. It is also important to understand these warnings are not exhaustive. SandenVendo America, Inc. could not possibly know, evaluate, or advise of all of the conceivable ways in which service might be done. Nor can SandenVendo America, Inc. predict all of the possible hazardous results. The safety precautions outlined in this manual provide the basis for an effective safety program. Use these precautions, along with the service manual, when installing or servicing the vendor.

We strongly recommend a similar commitment to safety by every servicing organization. Only properly-trained personnel should have access to the interior of the machine. This will minimize the potential hazards that are inherent in electrical and mechanical devices. SandenVendo America, Inc. has no control over the machine once it leaves the premises. It is the owner or lessor’s responsibility to maintain the vendor in a safe condition. See Section I of this manual for proper installation procedures and refer to the appropriate service manual for recommended maintenance procedures. If you have any questions, please contact the Technical

Services Department of the SandenVendo America, Inc. office nearest you.

SAFETY RULES

•Read the Safety Manual before installation or service.

•Test for proper grounding before installing to reduce the risk of electrical shock and fire.

•Disconnect power cord from wall outlet before servicing or clearing product jams. The vending mechanism can trap and pinch hands.

•Use only fully-trained service technicians for PowerOn servicing.

•Remove any product prior to moving a vendor.

SECTION I: VENDOR INSTALLATION

A.Vendors are large, bulky machines of significant size and weight. Improper handling can result in injury. When moving a vendor, carefully plan the route to be taken and the people and equipment required to accomplish the task safely.

B.Remove all tape, shipping sealant, and Styrofoam from the vendor. Loosen any shipping devices used to secure interior parts during shipping. Remove the wooden shipping base attached to the vendor base by the vendor leveling screws. Make certain the leveling screws are in place and functional.

C.Position the vendor 5.9 inches (15 cm) from a well-constructed wall (of a building or otherwise) on a flat, smooth surface.

IMPORTANT: The vendor requires 5.9 inches (15 cm) of air space from the wall to ensure proper air circulation to cool the refrigeration unit.

D.Adjust the leveling screws to compensate for any irregularities on the floor surface. Ideally, no adjustment will be necessary and the leveling legs will be flush with the bottom of the vendor. A spirit level is a useful aid to level the vendor. When the outer door is open, it will remain stationary if the vendor is properly leveled. Vendors must be level to ensure proper operation and to maintain stability characteristics. Do not add legs to the vendor.

The leveling legs shall not raise the vendor more than 1 1/8 inch (2.5 cm) above the ground.

E.Check the manufacturer’s nameplate on the left or right side of the vendor’s outer door to verify the main power supply requirements of the vendor. Be sure the main power supply matches the requirements of the vendor. To ensure safe operation, plug the vendor only into a properly grounded outlet.

DO NOT USE EXTENSION CORDS.

F.Recommended voltage specs = volts required + amps of circuit.

G.Dedicated 15A service required for 1 machine.

NOTE: Any power supply variance more than + 10% may cause the vendor to malfunction.

*Power outlets must be properly grounded.

*Power outlets must be properly polarized, where applicable.

Test the outlets using the following information.

(Refer to Figure 1 on Page S-4.)

SECTION I: VENDOR INSTALLATION (CONTINUED)

For Type 1 and Type 2 outlets, test for Grounding and Polarization as follows:

1.With a test device (volt meter or test light), connect one probe to the receptacle’s neutral contact and the other to the live contact. The test device should show a reaction.

2.Connect one probe to the receptacle’s earth contact and the other to the live contact. The test device should show a reaction.

For Type 3 through Type 5 outlets, test for Grounding as follows:

1.With a test device (volt meter or test light), determine which of the receptacle’s power contacts is the live contact.

A.Connect one probe to the receptacle’s earth contact.

B.Connect the second probe to the left (or upper) power contact. If a reaction occurs, this is the live power contact. If a reaction does not occur, move the second probe to the right (or lower) contact. A reaction should occur, indicating that this is the live power contact.

2.Connect one probe to the receptacle’s live power contact (as determined in step

1). Connect the second probe to the other power contact (neutral). The test device should show a reaction.

IF THE ABOVE CONDITIONS ARE NOT MET FOR THE GIVEN OUTLET TYPE, CONTACT A LICENSED ELECTRICIAN AND HAVE THE NECESSARY CORRECTIONS MADE.

SECTION II: ELECTRICAL HAZARDS

GENERAL

SandenVendo America, Inc. vending machines are provided with the appropriate power supply setting for your area. Some models are equipped with step-down transformers, as required. This enables the vending machine to operate on different main voltages. Refer to Section I. E. for information to determine the main power requirements. Refer to the appropriate service manual for details of step-down transformer operations.

The power sources just mentioned are standard for both household and commercial lighting and appliances. However, careless or improper handling of electrical circuits can result in injury or death. Anyone installing, repairing, loading, opening, or otherwise servicing a vending machine should be alerted to this point. Apply all of the normal precautions observed in handling electrical circuits, such as:

•Refrigeration servicing to be performed by qualified personnel only.

•Unplug the vendor or move power switch to off position before servicing or clearing product jams.

•Replace electrical cords if there is any evidence of fraying or other damage.

•Keep all protective covers and ground wires in place.

•Plug equipment into outlets that are properly grounded and polarized (where applicable), and protected with fuses or circuit breakers.

•All electrical connections must be dry and free of moisture before applying power.

A. Grounding Systems

SandenVendo America, Inc. vending machines are provided with the appropriate service cord for the power supply in your area. The service cord will connect to the matching electrical outlet. Always ensure that the outlet to be used is properly grounded before plugging in the vendor. (See pages S-3 through S-5.)

WARNING

ALWAYS TEST TO VERIFY PROPER GROUNDING PRIOR TO

INSTALLATION TO REDUCE THE RISK OF ELECTRICAL

SHOCK AND FIRE

The electrical grounding system also includes the bonding of all metal components within the vendor. This involves a system of bonding wires identified by green or green and yellow marking. The system uses serrated head screws, lock washers, and star washers to ensure the electrical connection between parts. Maintenance of vending equipment may involve disassembly. Include the above items when reassembling, even if the vending machine may appear to function normally without them. Omitting any

of these items can compromise a link in the grounding system. See the appropriate service manual or kit instructions for components and assembly instructions.

S-6

02/2008

SECTION II: ELECTRICAL HAZARDS (CONTINUED)

B.Servicing with “Power Off”

For maximum safety, unplug the service cord from the wall outlet before opening the vendor door. This will remove power from the equipment and avoid electrical and mechanical hazards. Service personnel should remain aware of possible hazards from hot components even though electrical power is off. See the appropriate sections of this manual for further information.

C.Servicing with “Power On”

Some service situations may require access with the power on. Power on servicing should be performed only by fully-qualified service technicians. Particular caution is required in servicing assemblies that combine electrical power and mechanical movement. Sudden movement (to escape mechanical action) can result in contact with live circuits and vice versa. It is therefore doubly important to maintain maximum clearances from both moving parts and live circuits when servicing.

WARNING

“POWER ON” SERVICING SHOULD BE ACCOMPLISHED ONLY BY FULLY-TRAINED PERSONNEL. SUCH SERVICE BY UNQUALIFIED INDIVIDUALS CAN BE DANGEROUS.

Power to lighting and refrigeration system is shut off automatically by the electronic controller when the outer door is opened.

NOTE: For power-on servicing of the vendor’s lighting system, turn lighting power on by accessing the Lights test function of the electronic controller (see programming on inner door).

For power-on servicing of the vendor’s refrigeration system, turn refrigeration power on by accessing the Compressor test function of the electronic controller (see programming on inner door).

1.0 Overview

The Vending Machine Controller (VMC) fitted to the 411VS & 411VSR is known as the MCB560. This is similar in design and operation to the unit fitted to the MARS SERIES 2000 BRANDED VENDOR (MDB board interface).

A maximum of 60 selections are made via a matrixed keypad ("A" – "F", "1" – "9", "*", "0", "#"), where a product selection is made by pressing one letter and one numeric key.

The VMC may be programmed using one of the following methods

1)Manual programming is performed with the door open using the mode switch (located on the VMC) and the selection switches.

2)Automated programming is performed by uploading configuration and/or price information from the DEX/UCS hard wired interface.

1.1Programming Guide

All programming is performed using the selection keypad. The board provides two interface modes - sales and service. Sales mode is accesed by pressing and holding the door switch for 5 seconds when the door is open. The service mode is accessed by pressing the mode switch on the VMC (the door must remain open while in service mode). Once in service mode the "#" key is used to scroll through the service modes. The available service modes are listed below.
