SECTION 5: Troubleshooting
E.
BIN
Below the product bin, there is an infrared emitter. Above the product bin, below the coin box, there is a detector.
The emitter projects 2 or 4 infrared beams, which are received by the detector. If an infrared beam is broken, the
display will show “
Remove Product
” in sales mode (door closed). To test these sensors, open the product bin.
In
Sensor Test
, the display should change from “
BIN
0” to “
BIN 1
.”
1. If the display does not change, check to make sure the port bin is flush with the door. Also, make sure the port
bin is relatively clean inside and clear of any debris that could be blocking the emitter and detector boards’
infrared beam.
(Refer to Figure 5.18.)
If the port bin is hanging open, reset the security latch on the port bin.
(Refer to Figure 5.19.)
If it doesn’t reset, check the white port bushings on each side of the port assembly.
(Refer to Figure 5.20.)
If the bushings are broken, replace them.
FIGURE 5.20.
White port bushings
Make sure these bushings are not broken. (
Note: Port
box housing shown with product bin removed for clarity.)
FIGURE 5.19.
Port security latch
Make sure this latch is not
stuck. It should move up and
down freely.
FIGURE 5.18.
Port bin
The front of the port bin should be flush (even) with the
front of the door and should be clean inside.
