OPTICAL VEND
This sub-menu provides the operator with options for designating product items or rows that are
monitored for product delivery by an optical sensor. Default is ALL selections ON unless changed.
Selections that are designated as Optical have an associated vend operation that differs from the normal
vend operation. For 5 milliseconds at the start of a vend, the Vigilant vend sensor is checked for blockage.
If blocked – the normal vend cycle is used and the optical sensors are ignored. Both the vend motor and a
10-second timeout timer are started.
• The motor rotates to the home-switch position.
• If there is a home-switch signal, the vend is considered successful.
• If there is no home-switch signal after 10 seconds, the vend motor is shut down and MAKE
ANOTHER SELECTION is shown on the display.
• The customer can then make another selection or press coin return. NOTE: Forced Vend is
overridden if Optical Vend is set.
If not blocked, the Vigilant vend sensor system is used. Both the vend motor and a 10-second timeout timer
are started.
• The selection motor rotates to the home-switch position.
• If a product is detected, the vend is considered successful.
• If, after reaching the home-switch position, a product has not been detected, the vend
motor will pause for 1 second while the VMC continues to monitor the optical sensor for product
delivery.
• If a product is detected during this pause, the vend is considered successful.
• If a product is not detected, the controller initiates a second vend cycle and a 9-second timer
while continuing to monitor the optical sensor.
• If a product is detected during this second cycle, the motor is stopped
immediately. The vend is considered successful. The 2nd Vend Count is increased by one.
• If a product is not detected before the motor reaches the home-
switch position, or if a 9-second timer runs out, the vend has failed or the selection is sold
out. Such a state will show MAKE ANOTHER SELECTION on the display and the amount of
credit. The customer can make a selection or press coin return.
