CONTROLLER FUNCTIONS
IVEND® CYCLE
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.
• I after 10 seconds there is no home-switch signal, the vend failed. The vend
motor is shut down and and MAKE ALTERNATE SELECTION 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.
Otherwise, if no product is detected, the selection is sold out. Such a state
will trigger the display of the
MAKE ALTERNATE SELECTION
message.
The amount of credit is displayed. The customer can press selection
buttons to activate this or another motor or press the coin return button.
o If after 10 seconds there is no home-switch signal and no product is
detected, then the vend failed. The vend motor is shut
down and
MAKE ALTERNATE SELECTION
is displayed. The customer can press
selection buttons to activate another motor or press the coin return button.
