L/R, F/B, U/D and freezer door motors.

keypad functions “

” can be used to scroll through each error.
Out Of Product occurs when the robot reaches the “virtual bottom” of the bin (2
predetermined encoder distances on the Z-axis; one for tall and one for short
bins)
•
Bin Load Error -
Occurs after the robot makes 3 unsuccessful attempts to vend
product from a single bin (vacuum seal is lost/product dropped) and puts that bin
out-of-order. 9 consecutive, vacuum related Bin Errors become a fatal error:
“
Vacuum Out of Order
” (see Fatal Errors). Typically due to robot programming,
misalignment, improper loading or using the wrong bin for a product. Use menu
