machine display will now show "Please Remove Your Product" and an audible beep will occur every 10 seconds until the product is
removed or one minute has elapsed. After one minute, the Delivery Door will close and the "Please Remove Your Product" message will
continue to be displayed. Once the product is removed and the Delivery Lift Sensors are no longer blocked, the Delivery Lift will return to
the bottom of the Delivery Box and machine display will return to the sales mode message and is ready for the next vend.
NOTE: If a customer grabs the product while the Delivery Lift is in operation, the Delivery Lift Sensors may detect a sensor blockage and will
stop the Delivery Lift at its current location. Pressing the flashing Blue Delivery Lift Button will also stop the Delivery Lift.

VEND CYCLE - IVEND® EQUIPPED
All vendor selections have been assigned at the factory to be monitored for iVend® optical sensing.
For 5 milliseconds at the start of a vend, the iVend® optical sensor will be checked to make sure it is not blocked, damaged or disconnected.
If blocked, damaged or disconnected - the normal home-switch-vend cycle will be used and the optical sensors will be ignored.
Both the vend motor and a vend timeout timer are started.
 The selection motor rotates to the home-switch position.
 If there is a home-switch signal, then the vend is considered successful.
 If after 10 seconds there is no home-switch signal, the vend failed. The vend motor is shut down and
is displayed. The customer can press selection buttons to activate another motor or press the coin return button.
If not blocked, damaged or disconnected - the iVend™ Sensor System is used. The vend motor and a vend timeout timer are
started.
 The selection motor rotates to the home-switch position.
 If a product is detected during this time period, then the vend is considered successful.
 If after reaching the home-switch position and a product is not detected, then the vend motor will pause for 1 second while the
controller continues to monitor the optical sensor for product delivery.
o If a product is detected during this pause, then the vend is considered successful.
o If a product is not detected, then the controller initiates a second vend cycle and another vend timeout timer while continuing
to monitor the optical sensor.
 If a product is detected during this second cycle, the motor will be stopped immediately. The vend is considered successful.
The 2ND VEND accounting counter is increased by one.
 If after reaching the home-switch position and a product is not detected, then the vend motor is stopped and for 2 seconds
the controller continues to monitor the optical sensor for product delivery. If a product is detected, the vend is considered
successful. The 2ND VEND accounting counter is increased by one.
