2 MACHINE CHECKING PROCEDURE
2.1 General
Check thoroughly through the dispenser to ensure that all the packs are correctly settled
on their respective shelves, and all loom wiring and system parts appear to be correctly
fitted. Do NOT touch any electronic board surfaces or wire ends with your bare hands or
tools as electrostatic discharge between you and any part of the electronic system can
easily destroy sensitive components.
2.2 Powering-up
Attach the Power Pack lead to the connector below it on the back of the Multivend
Controller board. The dispenser will power-up immediately.
2.3 Checking for basic operation
Press each product button in turn to check that all prices displayed by the LCD correspond
to the price card adjacent to the button.
Refer to Section 3 to resolve any unexpected responses until the dispenser performs as
expected.
2.4 Testing all the shelves
You should now check the correct action of every shelf by pressing each product button
and then inserting the right amount in turn and observing the corresponding shelf dispense
one pack. If any problems occur refer to Section 3 and then repeat these tests.
2.5 Coin system testing
Put at least three coins of every currently available national denomination into the coin
slot and check that the coin validation system and totalised value shown on the LCD
responds appropriately
– Please note the product needs to be selected before the coins are
inserted or otherwise the coins will be refunded. You should expect on average eight or
nine out of ten coins to be accepted by the system. It is likely however that dense round
coins (e.g. £1) will be more reliably validated than light ones or heptagonal ones (e.g. 20p).
You may carry out these tests with the door open. Note that any rejected coins or
validated coins cashed or refunded by the escrow will drop onto the floor unless you place
your hand or a suitable receptacle underneath.
If the system performance is not acceptable refer to Section 3.
2.6 Final vend checks
Close the door and using appropriate coins, vend one pack of each product. When this has
been completed open the door, replace all the vended packs on their correct shelves and
retrieve your coins. You have now completed the thorough checks necessary to establish
that the dispenser is functioning correctly, and in the case of a new installation the unit is
now ready for hand-over to the owner.
