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 machine knows that an item was delivered to the customer. If this beam
is not broken, the 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, Advanced
menu, Rows and Columns sub-menu, for instructions.
The Vigilant sensors are located inside the delivery bin as shown in Figure 17. 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 Motor Tests without product loaded, it is a good idea to shut off the Vigilant system.
