2.8 Customer hand-over
Demonstrate the operation of the dispenser to the customer as follows -
➢
Start with the door closed and locked. Show that each product button produces the
correct vend on the LCD, press a button and then insert some coins to vend at least one
pack.
➢
Show that the key turns the lock clockwise 180° to unlock and is then trapped until the
lock returns to the ‘locked’ position.
➢
Demonstrate how refill packs should be placed on the shelves to the right of the
spring-return red levers and show how to retrieve coins from the money box. Replace
the money box, shut and lock the door.
3 TROUBLE SHOOTING AND REPAIRS

3.2 Fault identification
Problems with the dispenser will generally fall into one of these two areas:
➢
Electronic system - failure to wake up, recognise or totalise coin values properly, or to
route power to the shelves to deliver packets.
The cause will often be resolved without spare parts – i.e. a loose electrical connector
requires re-connection, otherwise a system component may have failed and require
replacement. In all such cases it is extremely important to check through the system in
an orderly and logical way to determine the primary cause of the failure to operate,
because a fault in one component can easily prevent another fully operational part
from functioning correctly and thus appear faulty itself.
➢
Mechanical hardware - coins are accepted and totalised and the shelf motors function
but the dispenser fails to deliver packs, or obvious physical damage must be repaired.
In these cases it is much more likely that the fault will be localised and easily identified,
and the use of spare parts to replace faulty hardware will be straightforward and
obvious.
