VIGILANT VEND SENSOR SYSTEM
The Vigilant system is a series of infrared sensors that send a beam of light across the delivery bin. If this beam is broken
by a product, the Premium machine knows that an item was delivered to the customer. If this beam is not broken, the
Premium machine assumes that nothing was vended and turns the selection spirals by ¼ turns until a product delivery is
sensed. If, after the coils have turned a full revolution back to home without delivering a product, the customer will be
asked to make another selection or to press the Coin Return button to receive their money back.
Certain products can be problematic for any vend sensing system. Products that are very thin or very small in size may,
on occasion, miss the beams. With proper loading of the machine, sensing systems are irrelevant. A comfort level is
provided to customers who walk up to the machine and know, through technology, they will not experience a “rip-off”. For
this reason, a vend sensor system is desirable – however, if you vend very small or very thin items, you may want to
consider turning off your sensing system in case of malfunction via product size. See the Service Mode section of this
manual, Diagnostics sub-menu, for instructions.
The Vigilant sensors are located inside the delivery bin as shown in Figure 14 below. There is a red indicator light located
on the left side when viewing the bin from the inside with the door open. This light should be lit when the system is on,
indicating that there is power to the system. Blocking any of the beams turns off the red indicator light, which means the
system is working correctly.
Note: When performing Test Motors without product loaded, it is a good idea to shut off the Vigilant system.
